"Master, this vole seems to be crazy......" Zhao Si was a little surprised, and he said as he wrote hard in the booklet.

In the iron cage, the vole that was transplanted with "Killing Crystal" under its neck and was gradually waking up gave people a feeling that something was indeed abnormal, and its fur was covered with black gas, and its strength seemed to have increased a lot.

"Bang...... Bang bang ......"

The door of the iron cage was shaken by its head, well, it seems that the toughness of the body has also increased slightly, or rather, the body's resistance to blows has become stronger.

Zhao Ting also set his eyes on the crazy vole in the cage and looked at it carefully.

It can be clearly seen that the vole's eye sockets are deeply sunken and its pupils are red.

It stared at Zhao Si viciously, and there was a strong longing in its eyes.

Even Zhao Tai on the side was attracted by this strange appearance on the caged vole, he touched his chin and said in surprise: "This little guy is not going to evolve into a first-level "unknown", right?"

After looking at it for a long time, Zhao Tai shook his head again and said, "It shouldn't be, huh...... The body surface has not yet formed a "killing crystal film", and there is no "killing power" breath in the body, which should only be a simple mutation under the stimulation of "killing crystals". ”

"This little guy won't live long. ”

Zhao Tai's eyes were like torches, and he gave his own judgment.

Sure enough, as he expected, just a moment, the huge vole shrank rapidly as if a balloon had been deflated, and finally, the fur dried up and lost its luster, and the two little short legs kicked and ran out of air.

"It can last so long, and each body part has different degrees of alienation...... "Zhao Ting touched his chin and pondered, "Well, this vole is not simple. ”

"Zhao Si, bring my surgical box. ”

After a while, Zhao Ting carefully used tweezers to pinch out a small piece of snow-white, whisker-shaped grass from the stomach of the mutant vole, and put it in front of him to watch.

Before he could see what the result was, Zhao Tai stood up in surprise: "This is...... Snow Grass?"

"The whole body is crystal white and snow-white, like a beard, it is really snow grass!" After confirming that this grass plant is "snow grass grass", Zhao Tai suddenly felt like blood dripping and beat his chest, "Tyrannical things, if this "snow grass grass" is given to me, it is enough to make my blood concentration take a big step." It's a pity, it's sad, this kind of spirit grass was ruined by a beast......"

Zhao Ting saw him with a grief-stricken expression, and couldn't help asking, "Is this thing so precious?"

Zhao Tai explained with a dark face: "If it is only about spiritual power and medicinal efficacy, the "Snow Beard Grass" is naturally not the top spiritual grass. However, the "Snow Grass" is born in the winter season when the wind and snow are combined, and the more severe the weather, the more conducive to the survival of the "Snow Grass". At the same time, this spirit grass will only appear on the top of the mountain. The vast snow-capped mountains cannot be set foot on by humans!"

"It is precisely because this spirit grass is too demanding on the living environment that it is so difficult to find. It is precisely because it is difficult for humans to find it that it is so precious. ”

"Oh, that's right. Zhao Ting was stunned.

It seems that the reason why this mutant vole has been able to persist for so long under the poison of "Killing Crystal" is that it is only afraid that it has an inseparable relationship with this "snow grass".

Thinking of this, Zhao Ting turned his head and asked, "Si'er, where did you buy these voles?"

Zhao Si said weakly: "Two masters, what kind of "snow beard grass" are you talking about, is it really precious?"

"When the villain bought these voles from the hunter, he saw that he was feeding the rabbits with this grass...... According to him, this grass was found in the nest of an old rabbit in the depths of the Dageng Mountains, and there are many of them. He originally saw that the grass was crystal clear, like a medicinal herb, so he picked it up, but no one in the pharmacy in the city was willing to accept it, and the pharmacy shopkeepers said that this grass was not medicinal and was a waste grass. So the Orion can only feed the rabbits......"

"Feed the rabbits?" Zhao Tai almost fainted, "Hurry up and take me to find that Orion, if you can save some spirit grass, it will be some." ”

“......”

Seeing that the two were in a hurry to leave, Zhao Ting hurriedly added: "Remember to help me buy some rabbits again." ”

"Got it. ”

When Zhao Si and Zhao Tai arrived at the Orion's house, there were only about 20 "Snow Grass" left, and because of improper storage, most of the medicinal effects had been lost, and the angry Zhao Tai couldn't wait to lift the Orion's table.

Fortunately, under Zhao Si's persuasion, Zhao Taikan restrained his anger and spent money to buy the few remaining "snow grasses".

......

......

Another week has passed in the blink of an eye.

These days, Zhao Ting tried to transplant the "killing crystal" in the body of the old yellow skin into the body of many different mammals, sika deer, yellow rabbits, voles, weasels, etc., through continuous attempts, he came up with a new result.

The medicinal effect of "Snow Grass" can indeed greatly resist the inevitable rejection reaction caused by "crystal killing" transplantation, just like the pharmacological effect of "Poria Acid" on "heart transplantation".

Two days earlier, the first successful case of man-made "ominous" had appeared.

It is a very small vole, after transplanting the "killing crystal", this vole not only successfully survived, but also slowly generated a layer of "killing crystal film" on its body surface over time, and a faint black mist also appeared outside the body.

The rest of the body reacts in the same way as the natural "ominous".

After the vole had fully evolved and an anthropomorphic cold expression gradually appeared on its face, Zhao Ting's eyes were quick and he directly poked it to death with his dragon teeth.

With the experiments on the bodies of different species, Zhao Ting also found that the success rate of artificial "unknown" fluctuates according to the size of the species transplanted by "killing crystals".

The larger the species, the lower the success rate, and vice versa.

This result is supported by data, so far, there have been six ordinary voles that have successfully evolved into a first-level "unknown" after the "killing crystal transplant", and at the same time, there is a yellow rabbit and a sika deer.

Due to its large size, this sika deer devoured five "snow grasses" to withstand the rejection of the killing crystals and successfully evolve.

Both yellow rabbits and voles only need one or two.

Looking at the few dozen or so "Snow Grasses" left in the jade box, Zhao Ting decided to start trying to carry out "Killing Crystal Transplantation" on the human body.

"Zhao Si, Zhao Si," Zhao Ting shouted outside the courtyard.

Zhao Siti slipped the kettle in his hand and trotted in, and said with a smile: "Master, what variety are you going to buy this time?"

Zhao Ting waved his hand: "No need to buy animals anymore, Si'er, the master asks you, do you want to have special functions?"

"What is the special function?" Zhao Si looked confused.

Zhao Ting smiled slightly, smiling like a devil: "It's a special ability that others don't have, such as flying, retreating, breathing fire, freezing and other ......"

Seeing the warm smile on Zhao Ting's face, Zhao Si suddenly shuddered, shook his head again and again, and said, "No, no, the villain doesn't want to, how can the villain have such a blessing?"

Zhao Ting glanced at him, hated iron and said with hatred: "Look at your cowardice, you used to be an atheist, and you didn't even have the spirit of dedication to science." ”

"That's it, since you don't want to be a superman, then let the master come by himself. ”

Zhao Si's face fell, and he said tentatively: "Master, you don't want to transplant that piece of "Killing Crystal" into your body, do you?"

"That's right," Zhao Ting looked serious, and he didn't see any trace of joking, "Otherwise, why did I toss for so long? You must know that all the medical experiments that have been conducted on animals are ultimately to serve humans." ”

"Animals can only suffer most of the sins for human beings, and the remaining small part of the suffering is still for human beings to eat. ”

“......”

After all, this operation is not yet mature, and we are not 100% sure. ”

Zhao Ting's expression was solemn, and he said: "There is no surgery that will be 100% sure! Besides, the anti-rejection herb "Snow Mustache" is about to be consumed, if it is not used for human experiments, I am afraid that there will be no chance in the future." ”

"It's good luck to be able to buy snow grass this time, but we can't be lucky every time. How can this rare spirit grass, which was born on the top of a snow-capped mountain, be so easy to obtain?"

Looking at Zhao Ting's serious face, Zhao Si knew that he had made up his mind, so he gritted his teeth and said in a trembling voice: "Master, since this is the case, then let the villain first do the test subjects of the "Killing Crystal Transplantation" operation, the villain will die if he dies, and he will die ......."

"Shhhhh......h ”

"But ......"

"No, you're here to help me. Zhao Tingzheng said, "Oh yes, did you remember the bleeding stop method I taught you?"

Zhao Si looked stunned, hesitated for a moment, and said ashamedly: "Villain...... The villain didn't remember. ”

“......”

"That's it," Zhao Ting was a little speechless, "Then I won't take Ma Boiling Powder, I should have experienced Guan Erye's bone scraping and healing." ”
