"Damn it, this demon's blood has a corrosive effect on the black box!" Harden said with an ugly expression.

"Master Harden, how long can the black box last? Are there any spares?" said a legendary arcanist. "We will analyze the dark race elements in the blood as soon as possible to make a neutralizing potion, but this It will take some time."

"Not good! This demon is at the level of the heavens, and the blood cannot be carried in the existing container." He just took out a test tube to take some blood, but found that the test tube was also corroded.

This is an epic quality test tube!

"This was made in my spare time. There are several materials involved that are not available in the Western Continent. It is beyond my expectation to be effective on the portal. I hope it can last for a while." Harden The master shook his head.

Although Nibel used the broken star sword to successfully repel the giant demon claws protruding from the portal, he did not expect that the opponent's blood would have a strong corrosive effect on the black box. Once the black box is destroyed, there is no limit. The portal expands, and Crescent Forest will soon become a paradise for demons.

At this moment, Natasha suddenly thought of something, her eyes lit up and said, "Wait for me!"

Immediately, she slowly contracted the domain, and then she moved and disappeared in front of everyone.

In the card laboratory.

A knock on the door suddenly sounded, and Yan Chong just wanted to ask who it was when he heard the words, the next moment the door of the laboratory suddenly opened, and he was startled.

You should know that the laboratory needs to spend credits to enter, once you use it, you will not be disturbed, unless a tutor with higher authority can force the door to open.

Fortunately, his attention is on the side of the demon clone, and there is no potion or card drawing, otherwise it will definitely fail due to interference, and may even cause an explosion.

The production process of rare-level potions and cards is strongly disturbed, which may cause a violent explosion.

Although the third academy has deliberately trained the students to anti-interference dispensing and card making, they also scored the degree of interference.

Seeing the fresh and pleasant fragrance wafting by, Natasha appeared in front of Yan Chong like a teleport, and said anxiously: "It's too late to explain, hurry up and give me some blood!"

"What?" Yan Chong was stunned, but found that Natasha's domain opened up and enveloped herself. Yan Chong raised his arm without any resistance. At the same time, an incision was made in his arm, and blood flowed out of the wound. A flow of about hundreds of milliliters.

Rao is that he now has the strength of the golden rank, and the flow of so much blood at one time also made him feel weak.

The whole process did not take a few seconds. Natasha used her mental strength to put Yan Chong's blood in a crystal bottle, and then waved her hand, and an emerald green light enveloped Yan Chong's body and the wounds on her arms. He recovered instantly, the whole body was warm, and the feeling of weakness disappeared.

In the next moment, Natasha's figure disappeared again. If it hadn't been for the door to the laboratory opened wide, Yan Chong would have thought he had hallucinated just now.

"What's the situation?" Yan Chong was confused by Natasha's move. If it weren't for any killing intent on the opponent, he would have launched a hyperspace teleportation to escape back to the earth for the first time.

He quickly put away the potion materials on the table and some equipment he had brought, then ran out of the laboratory and flew into the air.

I saw many students rushing to the entrance of the sub-planes. Yan Chong randomly found a student to stop and ask, "What happened?"

"Don't you know?" The student said in surprise. "I heard that a portal appeared on the south bank of Jingyue Lake. Most of the legends rushed past. It is said that this portal leads to the world of demons. A giant claw came out and was cut off by Mr. Nibel."

After that, he left in a hurry.

Yan Chong quickly followed him to leave the secondary plane of the ancient tree and flew towards Jingyue Lake.

Next to the portal, Natasha's figure reappeared, pouring the bottle containing Yan Chong's blood towards the green demon blood above the black door frame.

Under the gazes of many legends, the green blood that corroded the black door frame like sulfuric acid touched Yan Chong's red blood and was fused into it, like a big fish eating a small fish, a blood mass formed by red blood. He opened a hole, sucked in the green blood, and then assimilated it.

Seeing that the blood had taken effect, Natasha continued to use Yan Chong's blood to neutralize the green blood. Soon, the green blood on the black door frame disappeared completely.

"What blood is this?" Master Harden asked, his eyes widened.

Natasha smiled slightly and didn't say much. The devil was at the other end of the portal. If she learns that the blood of the silver elf exists here, she will definitely use all means to kill Yan.

And Yan Chong also rushed to the north shore of Jingyue Lake, and no student dared to approach any further, they all watched from a distance.

With his extraordinary eyesight and hearing ~lightnovelpub.net~, he quickly learned the truth of what happened just now, and saw Natasha neutralizing the green blood of the devil with his blood, and I was shocked in my heart. Endless.

"I wipe it, is it possible that there really is some silver elf blood in my body?"

"No! It should be the demon eye bloodline that also has a restraining effect on the devil."

But next, Yan Chong thought of something, and his face looked a little ugly, because Natasha's behavior just now should be in the mindset of a try, but since it turns out that her blood can be used against the blood of the demon of the sky. , Then Natasha must be more certain that she has the blood of the silver elf.

"Dean Natasha, can you let me study the blood in your hands. You know, this blood is very strategic. Once it can analyze the ingredients used to restrain the devil, it will be for the entire continent. A great contribution!" Master Harden said eagerly.

At the same time, some arcanists, pharmacists and alchemists from the Third House also looked at the crystal bottle with Yan Chong's blood in Natasha's hand with fiery eyes.

"Sorry, I think our energy should be focused on the portal." Natasha shook her head and said.

"But this is not a contradiction! Some legends can be researched first, time is precious!" Eric said.

"I need to protect the privacy of the blood owner!" Natasha still refused.

You know, blood can analyze the owner's genes on the earth, and on the endless continent, as an important medium, the use of prophecy can obtain a lot of information about its owner!

For example, the position, image, strength and rank of the blood master, etc., especially in the hands of some special professionals, and even curses can be imposed on them!
