According to the requirements of the phagocytic system, upgrading the main bloodline requires two thousand bloodlines and the corresponding bloodlines.

Today, Lu Ping's blood value has accumulated to more than 1,900, which is almost the same, and it can easily be filled.

The so-called "corresponding blood" will be more troublesome.

Because Lu Ping's bloodline attributes are all five elements, that means that at least five high-quality bloodlines need to be consumed.

Moreover, there must be no conflicts between each other, and they must be mutually compatible in order to be integrated into Lu Ping's body bloodline.

The only thing to be thankful for is that the bloodlines you want are all top grades of the Profound Rank. In case you need five bloodlines of the Earth Rank, Lu Ping'an simply can't afford it, and there is no place for him to hunt nearby.

Soon, Lu Ping'an came to the Wanrong Commercial Bank, a shop that sold animal cores.

The one who came to receive him this time was a pure and lovely little girl, who kindly asked Lu Ping'an's needs in an extremely sweet and beautiful voice.

Lu Pingan didn't say much, he showed the jade card directly, and said, "I need a high-grade Xuan-level beast core, but the requirements are more special. I can pick it myself, and I don't need to trouble you."

The little girl was slightly startled, and immediately said with a smile: "Please, please."

With that said, the little girl led Lu Pinggan to several large shelves inside the store, and said, "The best Xuan-level high-grade beast cores in our store are basically here. You can choose slowly. Where you need help, just speak up."

Lu Pingan asked, "Basically? Isn't it all?"

The little girl said: "If you have special needs, we can still find it for you. Of course, you have to wait a few days, and there is no guarantee that you will find it."

Lu Pingan said: "Linzi is worthy of being a big city backed by Jixia College. Even the Wanrong Commercial Company here has a more thorough hospitality."

The little girl smiled and said, "Because people at Jixia Academy occasionally have similar requirements. Since the guests have needs, we will naturally provide corresponding help."

"Well, let me see for myself."

After that, Lu Ping'an turned on the devouring system to detect the various beast cores on the shelf one by one.

The little girl's thoughts are the same as the guy in the Luotian City branch before, thinking you just look at it like this, can you really see anything?

Even the pharmacists or instrumentalists at Jixia Academy still need to touch them with their hands before they can perceive them clearly.

Lu Pingan didn't know the little girl's thoughts. He was looking at the various beast cores in front of him, and he felt once again that the big city of Dongyu Kingdom was indeed different.

The types of beast cores stocked in this shop are extremely rich, with all kinds of weird ones, much better than the branch in Luo Tiancheng.

Lu Pingan originally thought it would be quite troublesome to find beast cores that meet the system requirements, but he did not expect to find four beast cores after testing all the beast cores in the store, all of which have different attributes, showing "extremely High-quality animal nucleus, and there will be no side effects between each other.

"There is still a beast core with extremely high fire attributes. It seems that they can only help them find it."

Lu Pingan thought so in his heart, and was planning to buy some more for absorption and refining.

At this moment, I saw a tall and thin middle-aged man walked into the shop and asked, "Did you get the high-fire beast core that I wanted before?"

Another guy stepped forward and said respectfully: "I have found it, please wait a moment for Elder Yan Kang, and I will bring it for you."

"Trouble."

The man said, sitting on a chair and waiting.

Lu Ping'an was curious, and whispered to the little girl next to him, "Who is the elder of Jixia Academy?"

The little girl said: "Yes, and it's the elder of the Medicine Pavilion, with a distinguished status. This time it is estimated to be on the way, so I personally came to get the animal core.

When Lu Ping'an heard the words, his eyes condensed, and the intention of meeting was immediately born.

The reason is very simple. Even if he finds the pill for the Nine Turns Back Soul Pill, he has gathered the materials, but he always needs people to refining it.

The way of refining medicine is not something that can be learned overnight. Lu Ping'an is now holding onto the Buddha's feet temporarily, I am afraid it is too late.

But if you know a Yaoge elder, maybe you can ask him for help in the future.

Therefore, Lu Ping'an said, "How many high-fire beast cores did he ask for?"

The little girl said: "I'm really sorry, this belongs to the privacy of the guest. Even if you are our distinguished guest, I can't disclose it to you privately."

As soon as the voice fell, the guy on the other side, carrying a wooden box, walked to the elder named Yan Kang.

"Elder Yan, these are the twenty high-fire beast cores you want, please have a look."

The little girl smiled helplessly and said, "It's none of my business."

Lu Ping'an's gaze paused for a moment between the beast cores, and with a smile, he walked over there.

Feeling a stranger approaching, Yan Kang looked up and asked, "Is there anything wrong with this little brother?"

Lu Pingan said: "I happen to be short of a highly flammable beast core like yours. Can you give one to me? Or it's okay for me to pay more."

Yan Kang said: "What are you using for? The so-called high fire is divided into many kinds. How do you know that I am what you need?"

Lu Ping’an said: “If I’m not mistaken, this is the beast core of the Burning Fire Rat. It is a top grade of the Profound Rank, with extremely high and pure fire. The most peculiar thing is that it does not absolutely reject water attributes. This should be the same as Burning Fire. Is the rat's growth environment more special?"

Yan Kang was surprised, and subconsciously glanced at the shop assistant beside him, thinking it was the news revealed by the people in their shop.

The guy waved his hand quickly and said, "Don't get me wrong, Elder Yan, we will never reveal your purchase privacy."

Yan Kang returned his gaze to Lu Ping'an, and said in amazement: "That is to say, is this really what you see?"

Lu Pingan smiled and said: "Yes, if you don't believe it, you can also take out the beast core to verify my discrimination ability."

As soon as Yan Kang stretched out his hand, he called out a black beast core and said, "If you can tell the attributes of this beast core, I will give you one of this highly flammable beast core."

Lu Pingan started the Devouring System while unceremoniously said, "That's good."

Yan Kang raised his palm and said, "Do you need to hold it in your hand and feel it?"

Lu Pingan shook his head. After reading the test results in his mind, he said directly: "This is the beast core of the'cloud black raccoon'. It is a lower grade of the earth. It is characterized by a cloud-like black gas, which is confusing. It also has certain wood properties."

Yan Kang's eyes shone slightly, which made him truly surprised.

Just because this beast core is extremely rare, when he first obtained it, he had to perceive it carefully, and then recall the classics he had read before he could judge it.

But Lu Ping'an didn't even touch it. He could tell the accurate result only by the perception of the air. With such a talent, Yan Kang had never seen it among the many students in the Academy's Medicine Pavilion, which made him look different. .

"Little brother, may I have your surname and name? Where do you learn from?"

"My name is Lu Pingan. As for the teacher and student, I'm really sorry for the inconvenience, but I can tell you that I am not a student of Jixia Academy."

Yan Kang felt a little regretful, and said, "That's a pity, otherwise I would like to ask you to try our medicine pavilion."

Lu Pingan said: "I'm not interested in learning refining medicine, but recently I was looking for an elixir called'Nine Turns Back Soul Pill'. Have you ever heard of it?"

Yan Kang said: "I have heard it before, but it seems to exist only in rumors, and there is no actual existence."

Lu Pingan frowned slightly and said, "Then can you find relevant clues in the Wanjuan Building of your college?"

Yan Kang said: "I really don't know this. Wanjuanlou has a vast collection of books. Although I have read a lot of medicine, but it is not all."

Lu Pingan said: "Understood, thanks for the answer."

Yan Kang took out a beast core from the box and handed it over.

"Although I don't know why you are looking for such a vague and illusory medicine, I still wish you good luck."

In addition to refining medicine, Yan Kang didn't seem to care about Lu Ping's way of entering Wanjuanlou as an outsider.

Lu Ping'an took the beast core and said, "Then I would be more respectful than fate."

After that, Yan Kang stood up, put away a box of beast cores, and paid the buddy. Before leaving, he said to Lu Ping An, "If you want to learn medicine in the future, you can come to the medicine pavilion of Jixia Academy to find me. , Just report my name."

Lu Ping'an said, "I don't want to learn to refining medicine, what else?"

Yan Kang hesitated for a while, and said, "If I have time, that's fine."

Lu Ping'an laughed and said, "Okay, then it's a deal."
