After blasting away Robust III, who was trying to make money at both ends, Yun Na sat in the same place for a while, thinking that he had just slept and was full of stats anyway, so let's just brush the new skill of Breath of Insect.

Just do it. The new skill comprehension requirement of Breath of Worm is to be poisoned up to 99 times. Recalling the story of the past, Yun Na realized that apart from being drugged by Ghost Dance Tsuji in Infinite City, the rest of her poisoning was basically caused by the butterfly pit in the butterfly house. A few times she encountered the poisonous snake in the suburbs. The monsters of this kind are sometimes hit. Although the number of poisonings did not reach 99, it is not far from 99.

Take out a detoxification medicine from his backpack (after practicing as a pharmacist, Yun Dan also made 999 bottles of ordinary poison and medicine), and took out a row of antidote. Yun Dan took a deep breath and began to pinch his nose. Pouring a bottle of poison into his stomach.

I have to say that, thanks to the regular testing of the drugs requested by Butterfly Ninja, Yun Nai is already familiar with this process. Just after pouring a bottle of poison, she immediately felt blurry in front of her eyes and cramps in her belly, and at the same time instinctively knew that she would lose 1% of HP every time she moved one square.

Because I have tried many poisons and drugs, I know exactly what discomfort this thing will cause, and the impact on attributes may include one or more of the decline in HP over time, the number of moving steps, and the number of rounds, so Yun Na only put the antidote in advance within reach. At this time, she did not hesitate to clutch her belly, with a pale face, picked up a bottle of antidote and drank it, her movements were extremely skillful.

Number of poisonings 1.

At this time, Yun Nai didn't stop, but eagerly picked up the second bottle of poison and continued to drink.

Number of poisoning 111...

Yun Na drank poison like a drunkard. But the tips for acquiring the new sword skill of Insect Breath have never come out. After drinking about twenty or thirty bottles of medicine, she finally felt that she had lost too much HP, so she lay back on the bed and decided to sleep again. (With a bed next to her, Yun Nai like an iron rooster will never waste healing medicine. ).

Just as drowsiness was brewing, a soft "quack" sounded from the window suddenly. As soon as Yun Na opened his eyes, he found that the crocodile she had sent during the day had flown back, and was bounced by the window looking at her.

Probably the letter from Immortal Kawasiya came. Thinking of this, Yun Na sat up from the bed again and squeezed its stomach while holding the crow.

The croak gave a "croak" and spit out a few wet letters from his mouth.

Is there more than one letter? Yun Na was a little curious. He picked up the letter and looked at it. He found that the four letters came from the immortal Kawasami, the brothers and sisters of Zaomen, the Yanzhu Beimingyu Xingming, and Yushiro.

Fushikawa Shiya’s reply was somewhat disgusting, indicating that he would try the method of comprehension; the Zaomen brothers and sisters and Yuanyizhi's letter asked her about her recent past week; the letter from Xinming Yu Xingming said that he received She was very grateful to the mermaid meat and the leaves of the world tree that she sent by the stone murderer. These contents are not unexpected by Yun Nai.

However, the content of the letter sent by Yushiro was very strange. He didn't say anything, but just asked Yun Nai to meet him and said that there was something important to discuss with her.

When seeing her, Green Mao, who was so foul-faced, had something to discuss with her? Probably there is something to ask for. For a while, Yun Na became nervous. What is the urgent matter that caused this green problem to be rushed to the doctor and even found her?

Yun Na didn't care about sleeping anymore at this time. Thinking that it was night, it was the time when Zhu Shi and Yushiro could move, she immediately saved a file, and then directly took out the portal and put it on the ground. The destination was Tokyo.

...

Yun Na soon came to the small alley where the Zhu Family was located. After confirming that they did not move this time, Yun Na walked through the Muyin Wall and walked in.

The cold moonlight illuminates the Zhu Family Medicine Garden, and the flowers, trees and herbs sway in the breeze. Yun Na walked into the yard and glanced around, but found no one.

"His, here!"

Yushiro's voice suddenly sounded in his ears. Yun Na immediately turned around and followed the voice, but only found an empty wall root.

Obviously there is not even a ghost shadow there, why does Yushiro's voice sound? Yun Na was taken aback, and suddenly realized something.

That guy used blood ghosts!

Thinking of this, Yun Na immediately fetched a piece of "Muying Talisman·Xian" from Yushiro's in the past and pasted it on his forehead. Then she looked in the direction where the sound was coming from, and suddenly found that the green-haired figure appeared in front of her eyes-this guy was squatting on the wall, with a baby face extremely serious, and his brows twisted into twine. But even so, he still didn't move, but stayed where he was and waved at her very anxiously.

Although this process is like the puzzle-solving link in RPG, Yun Nai, who successfully solved the puzzle, is not at all excited-Yushiro is talking to her in his own home and has to secretly hide himself with blood ghosts. What exactly is going on?

"Faster!"

Hearing the sound, the green hair even became a little impatient. At this time, Yun Na didn't have time to care about anything with him, so he immediately walked over.

"Why do you still use blood ghosts?" Yun Nai asked uneasy immediately as soon as he walked to Yushiro.

"...Of course it's because you have to avoid Master Zhushi! Stupid woman!"

Yushiro looked at the stone murderer with a foolish look. Yun Nai is very clear about his appearance, obviously it is the rhythm of blowing people up and down at the touch of his mouth. But this time, Yushiro didn't know what he thought of, so he swallowed the words spraying her abruptly.

——Yun Yan made a "thump" in his heart, and he became even more disturbed.

Yushiro didn't know what he was thinking, his face turned pale. He took a deep breath and solemnly said to Yun Nai: "I found something wrong with Lord Zhu Shi."

Yun Na said in his heart that it really had something to do with Zhu Shi: "What's wrong with her?"

"...Do you remember that when we changed the Stove Gate You Douzi from a ghost to a human, Lord Pearl asked you for five leaves of the World Tree, right?"

Yun Na nodded, indicating that of course he remembered. Yushiro sighed and said, "In fact, you only need a leaf of the World Tree to make the potion for your beans."

"Huh?" Yun Na was taken aback, and asked quickly, "The remaining four leaves?"

"It's Master Zhushi who asked you so much without telling you." Yushiro replied.

Yun Na was taken aback: "Why don't you tell me?"

"I'm sorry." Yushiro looked away and said shamelessly, "At that time, I was very happy to find that the silly Lord Zhu Shi also learned to cheat others. At the same time, I further felt my heart when facing you. The guilty and uneasy Master Zhushi is as cute as a kitten walking on an eggshell, so there is no plan to tell you at all."

"..."

Yun Na was speechless. This guy is too shameless, right? And when I mentioned Zhushi, I started to use long sentences, which made people want to beat...

Resisting the uncomfortable feeling in his heart, Yun Na continued to ask: "What did that world do with the leaves of the World Tree?"

With Yushiro's explanation, Yun Nai understood the cause and effect. It turned out that after Zhu Shi asked Yun Na for four more leaves of the World Tree, she locked herself in the laboratory on the day Yun Na left with the stove door Nidouzi, and started research day and night. She didn't even let Yushiro intervene in this research. During this period of time, Yushiro saw an unknown crocodile flying into Jushiro's room from the window, but when he asked Jushi afterwards, Jushi denied it, which seemed rather strange.

"The thing that makes me feel the most wrong happened today." Yushiro said this, with an ugly sigh, "Master Zhushi asked me about my future plans this morning. I replied that I wanted to follow her in medical practice. Save people. But she didn't say anything at the time, but turned Chachawan into a ghost in the afternoon."

"Chachawan?" Yun Na was taken aback, "Isn't that the three-flower cat?"

"Yes." Yushiro nodded, "The reason why I used blood ghost magic to hide here is because I am worried that Chachawan will find me and make Master Zhushi suspicious. After it becomes a ghost, the nose becomes more alert. But fortunately, Now it should be playing with the orange cat raised by Hayakawa outside the alley."

"The series of Lord Zhushi's behaviors are really abnormal. Because she has been guarding me, and my strength is weaker than her, it is not convenient to investigate, so I wanted to find someone for help. After thinking about it for a long time, I finally thought of you."

Yushiro asked seriously: "Unna, can you help me investigate what happened to Lord Zhushi?"

As soon as this green hair voice fell, the system immediately popped out a prompt.

[Commission from Yushiro: The Secret of Zhushi. Master Zhu Shi has been behaving abnormally recently. I am very worried. Can you help me find out her secret plan? Y/N】

[Reward Yushiro's favorability rating of 99 after completion]

Looking at the reward, Yun Nai immediately decided to take up the task. To be honest, the favorability of this stinky green hair is too difficult to brush. However, Zhu Shi is an important person to help her improve the progress of the main line, even if she does not reward her, she intends to understand the situation.

What's more, this "Secret of the Pearl World" mission reminded her of the mission of "Butterfly Ninja's Secret" that was very troublesome. The patterns of the two tasks are almost exactly the same, the names are "secrets", and the delegates are not the person himself, but the relatives and friends, which makes Yun Nai feel a little bad foreboding in his heart...

With a wave of his hand, Yushiro let out a sigh of relief and looked at her with piercing eyes: "Then please. I am here waiting for your news."

After speaking, Yushiro shrank in the corner again and did not move. Going to talk to him again, he will only say one sentence over and over again: "What are you stupidly doing here? Hurry up and investigate!"

It seems that the mission has just begun.

Yun Na thought for a while, first saved a file, then put on a jersey that reduced his sense of existence, and posted a few hidden seals, and threw out a wave of Shiki God paper men to carry out "Automatic Shiki God Investigation". Then he raised his leg and walked in the direction of the small bungalow.

To be cautious, she also did not intend to let Zhu Shi discover her existence.

After entering the small bungalow, Yun Na first walked towards the secret door leading to the underground laboratory. However, when she reached the door, she found that the door was locked and could not be entered.

The stone murderer was thinking about whether to offer curry sticks directly, knocking on the door, and the system suddenly gave a prompt.

[At present, Zhushi is conducting research in the laboratory and cannot talk. Please come after the research is over. 】

[01:37:33 until the end of the study]

As soon as the system prompt came out, Yun Nai immediately understood, and quickly put away the curry stick in his hand-now I can't smash the door, Zhu Shi did not go out to practice medicine tonight, but was in the laboratory, and he would kill her as soon as the door smashed. disturb.

The system that seemed to prevent her behavior actually provided her with information that Zhu Shi will leave the laboratory for an hour and a half. During this time, except for the inaccessible underground, she can let her go in other places. Free investigation. Thinking about this, Yun Nao ran directly to the second floor and got into Zhushi's room.

Zhushi’s room is quite spacious, but the furnishings are very simple. The furniture only retains the necessary beds, tables, dressing tables and cabinets, and they are all in a simple and Japanese style, where everything is clear at a glance. This also reduces the difficulty of searching a lot. And there are still rustic bottles in her boudoir.

Yun Na walked into Zhu Shi's room, in case she suddenly came back in the middle of the experiment and locked the door specially. After that, she walked to the bottles and cans in the corner, smashed them with ease, picked out a guardian seed from the inside and ate it. Then Yun Nai began to look around for a while.

There are several medical books in the bookcase to study the metabolism of the human body. On the dressing table are combs, ribbons, hair accessories and cosmetics. After opening the drawer of the dressing table, Yun Na saw a piece of black underwear in it...

System prompt: [Get the underwear of the Pearl World×1, defense 50 after equipped, a small amount to increase charm]

Who can equip other people's underwear!

Although he complained in his heart, Yun Nai put away Zhu Shi's underwear without saying a word, and prepared to bring it to Yushiro later. However, after picking up her underwear, how did Yun Na find that there was a small book under the drawer.

what is this? Yun Na picked up the little book in a little bewilderment to check it, and saw the system pop up a prompt.

[Get Zhushi’s Diary]

The diary is a good thing. Many clues in RPG games are found in the diary. Thinking of this, Yun Na immediately picked up the diary, sat down at the table, and looked through it without guilt.

Some of the previous content recorded the daily life of Zhu Shi, including the kind of patients that I met today when I went to practice medicine, what is the progress of today's research, and what interesting things Yushilang and Cha Chawan did. But all the way to the day when Yun Nai brought the Stovemen Nidouzi to Zhushi to help the Summen Nidouzi from a ghost to a human, the record in the diary changed.

x month x day

Yun Na told me that she could find the leaf of the World Tree. is that true? Does that kind of thing really exist? ...No, I can't make a final conclusion yet, I will have a look at it in a few days.

x month x day

It was unbelievable that a traveling merchant actually sent the leaf of the World Tree. Even if the animals he brought ruined the medicine garden, I didn't care anymore. Yun Na gave me five leaves of the World Tree and asked if I wanted so many. I gave an affirmative answer, but in fact, only a leaf of the World Tree is enough to make a potion that transforms ghosts into adults. I deceived her, but I can also start my research.

x month x day

The things Mr. Ji Guoyuanyi faced at the beginning must not be allowed to happen again. This time I must help the ghost killing team. I sent a letter to the leader of this generation, and he agreed to cooperate with me. Must seize this opportunity to completely eradicate Ghost Mai Tsuji Wu Mi, and never let him find another chance to escape.

x month x day

The research fell into a bottleneck, and in desperation, I had to ask the ghost killer team for help. I didn't expect him to let Ms. Zongzhu Butterfly Ninja communicate with me. In this way, it will be possible to successfully develop a drug that suppresses misfortune.

x month x day

The research was successful.

x month x day

I don't think I can survive the battle. Oni Mai Tsuji Muzai will definitely kill me as soon as he sees me. I, a sinful person, has stolen his life from the sky so far, but if I die, Yushiro will definitely be lonely. It would be great if Cha Cha Wan was willing to accompany him instead of me. Ask Cha Cha Wan for your opinion later.

...

The diary is terminated as soon as it is written, and the date of the last diary happens to be today. Of course Yun Na knew what happened today. Yushiro tells her that Zhu Shi has transformed Chachawan into a ghost.

In other words, Zhushi secretly lied to a few leaves of the World Tree in order to make some kind of medicine that can suppress the misery of ghost dance Tsuji... Although the successful production of the drug made Yun Nai happy to hear about it, he learned that Zhushi decided to sacrifice. For herself, it was not in her heart.

The investigation is not over yet, so let's look for other clues first.

After leaving Zhushi’s bedroom, he searched several rooms and found nothing. Eventually, Yun Na came to the study, flipped through the bookshelf, and suddenly found a stack of letters.

Yun Na glanced at the title and found that it was a communication between Zhu Shi and Butterfly Ninja, and immediately opened it and read it.

It turned out that after obtaining the leaf of the world tree and successfully making the racial transformation potion, Zhushi planned to inject the potion into the body of Oniwu Tsujimu. However, considering the fact that Kokuenyi's strength suppressed Oniwu Tsujimu's, but he was still split and escaped, Zhushi felt that the racial transformation potion that had only one effect was likely to be decomposed by Oniwu Tsuji's, so he planned to further develop it. A multi-effect potion.

After discussing with Butterfly Ninja, the two finalized the estimated effect of the medicine: first try to make Guimai Tsuji into a human being, if it fails, then use the opportunity of him to break down the drug to accelerate his cell metabolism and make him age quickly. In addition, considering that he may split and escape, the split must also be suppressed. It would be better if he could destroy his cells...

——Predicted all the impossibly possible actions of Oni Mai Tsuji, these two people are really cautious! Yun Na looked a little shocked. Has this medicine really been developed?

The system prompts that the collection progress has reached 100%. Yun Na held the letter between Zhu Shi and Butterfly Ninja for a while, and then instinctively put the letter into his backpack and walked out of the room.

After going downstairs, Yun Na ran to the stairs leading to the basement and took a look, and found that the door was still locked.

[At present, Zhushi is conducting research in the laboratory and cannot talk. Please come after the research is over. 】

[00:49:03 until the end of the study]

Yun Na pushed the door, but found that he couldn't open it, so he had to go downstairs to find Yushi Lang for a mission.

When he walked out of the small bungalow, he found Yushiro still squatting in the corner, and Yun Na suddenly hesitated. However, Yushiro saw her sharply, and immediately waved at her, and a red exclamation mark appeared on his head.

In desperation, Yun Na had no choice but to run over.

"How about it, did you find anything?" The green hair asked eagerly as soon as he ran to Yushiro.

Seeing Yushiro's eagerness, there was nothing he could do, Yun Na had no choice but to say what he saw in the diary and the conversation between Zhu Shi and Butterfly Ninja in the letter.

While explaining what he had read in Zhushi's diary and correspondence, Yun Nao watched Yushiro's expression. Seeing Yushiro, who was still anxious just now, was completely stunned. The expression on his face was completely stiff. The domineering gaze in his eyes that was originally burning flame gradually went out. Yun Na couldn't help but pat his shoulder and asked. Said: "Are you okay?"

"...Huh? Ah..."

Yushiro seemed to come back suddenly at this time, nodded, and then pulled her hand away stiffly.

Yun Na stared at him without blinking, worried that Yushiro would do something irrational because of his inner collapse. But to her surprise, Yushiro appeared very calm, and even thanked him politely: "Anyway, thanks to you this time, let me know what Lord Zhushi thinks. Thank you."

"……you are welcome."

The system prompts Yushiro’s commission [The Secret of the World of Pearls] has been completed, and Yushiro’s favorability is 99. But the more Shirou became calmer, Yun Nai became more and more disturbed.

He is too abnormal.

While she was standing beside Yushiro in silence, the green hair asked her calmly, "What's wrong? What are you doing here? Haven't your ghost killing team been very busy these days?"

"Ah...hmm."

Yun Na hesitated and nodded.

"Huh? Then don't you hurry up and practice?" Yushiro suddenly lifted the corner of his eyes when he heard the words, and sprayed at Yun Nai unexpectedly, "Are you trying to be lazy? Give me training! Since Lord Zhushi said to defeat Guiwu Tsuji Wumisao, then you must fulfill her wish! Listen to me, no matter what time and place, Lord Zhushi's wish is the first priority!"

"..."

The corner of Yun Na's eyes twitched, and his heart said why the old lady has to stand here and listen to you spray? The hesitation just now disappeared, she rolled her eyes unceremoniously, just about to say something, suddenly her body uncontrollably stepped automatically and left the wall of Mu Yin.

What's the matter, she didn't plan to leave just now?

After standing on the other side of the wall of Mu Yin wondering for a while, Yun Nai quickly determined that this must be a compulsory plot.

The alley was quiet, and the shallow moonlight spread through the gaps in the walls. Yun Na just wanted to take out the portal and send it back. Suddenly he remembered that it was a rare visit to the Zhu Family. Why didn't you take a few herbs?

I don't know if the system can force her to turn around and then go back... it should be possible, right? Thinking of this, Yun Nao didn't say a word, rolled up his sleeves and prepared to go back. Unexpectedly, she had just stepped across the wall of Mu Yin when she suddenly heard a depressed cry.

"..."

Yun Na stopped and looked in the direction of the cry. The "Muyin Talisman·Xian" attached to her body has not been removed yet, so I saw Yushiro who was still driving people away just now. At the moment, she is sitting alone in the corner, curled up, holding her hand up and holding it. Secretly crying in both eyes.
