Yanagiso.

Quiet room.

Zhao Ting wore homemade silk "sterilization" gloves, and used homemade tweezers to pick up a black and shiny diamond-shaped crystal about half the length of a little finger, and put it in front of his eyes to observe it carefully.

Lying quietly beneath him lay several disemboweled, blackened weasels, little things that had apparently been dead for a long time.

According to Xiao Tai, this crystal should be the "killing crystal" in the body of the "ominous". Zhao Ting muttered, "Judging from the results of the current experiment, the effect of this "Killing Crystal" is quite ...... Converter?"

After a long period of testing and research, Zhao Ting gradually discovered that the function of this black "killing crystal" taken from the body of the second-order unknown "old yellow skin", an inch from the neck and half an inch to the right of the heart, seemed to be...... Actively devour the vitality of other life forms and transform them into "killing power"!

When this "Killing Crystal" was first taken out, the black light on its surface was dim and inconspicuous.

But just when Zhao Ting tried to transplant this black "killing crystal" into the body of an ordinary weasel and wanted to make an artificial "unknown", he found that there was a rejection reaction between this black "killing crystal" and the transplanted host.

What's even more unexpected is that the two not only produced a rejection reaction, but not long after the rejection reaction, this "killing crystal" completely engulfed the vitality in the host's body.

After the transplantation, Zhao Ting watched the coat color of the weasels on the ground gradually dim, and his eyes spread, but this "killing crystal" became crystal clear after swallowing the vitality in the bodies of several weasels one after another.

Zhao Ting felt that this "Killing Crystal" seemed to have its own consciousness!

No, it can't be said that from the current research results, "Killing Crystal" is more like ...... Cancer cells, which are not only highly aggressive, can invade the living system of the host indefinitely, taking away life. It can also convert the vitality that has been won into "killing power" and store it in crystals.

For this result, Zhao Ting had a bold conjecture.

What if there is no rejection during the transplantation process? If the transplantation is successful, will this amulet become an engine?

The killing power in the body of the "unknown" is first transformed from the outside world by the converter of "killing crystal", and then it acts as an engine to distribute the killing power to various parts of the body one by one.

It can be seen that the importance of "killing crystals" to "ominous".

However, how to overcome this natural rejection?

Zhao Ting thought silently.

"Well, we need to do clinical trials to see if there are any successful examples. ”

Thinking of this, Zhao Ting raised his head: "Zhao Si, Zhao Si, go and help me buy some weasels to ......"

......

......

More than a month passed in the blink of an eye.

Outside Yanagi Village.

I don't know when it snowed, and the snow fell to disperse the rootless fog and cover up the chaos in the world.

Zhao Tai rode a red high-headed horse from the official road, and the sound of horses' hooves was like a drum.

Tethering the horse to the willow tree in front of the door, Zhao Tai walked straight into Zhuangzi.

"Brother, I just saw Zhao Si driving to the east from a distance, why did he go?"

Zhao Ting didn't raise his head, he was still busy with his own affairs.

"It's nothing, I asked him to buy something for me. ”

He said casually, and Zhao Tai didn't ask any more questions, and sat on the chair next to him to rest.

After a while, Zhao Tai really couldn't help but ask, "Brother, what are you tossing these weasels for?"

“......”

"What do you mean by tossing?" Zhao Ting's expression darkened, "I'm doing a clinical trial, eh, I haven't asked you yet, where have you been these days?"

Zhao Tai spread his hands and said, "Where else can I go? With the situation of the two of us, we can't go back to home, hey." ”

After a while, he said again: "I went to Qingzhou Mansion and sent the news of "Lin Zifeng's suspected death" to the Lin family of the Spirit Clan, guess what?"

"What's the matter?" Zhao Ting asked.

Zhao Tai smiled bitterly: "The people of the Lin family have long had the means to confirm that Lin Zifeng is dead, that is to say, the corpse in the yellow skin's lair is indeed the genius of the Lin family-Lin Zifeng!"

"Fortunately, my trip is not without gain, I learned that the Lin family has sent a spiritual cultivator from the Divine Refining Realm to come to the mountain city to investigate the cause of Lin Zifeng's death, hmm...... That senior may have been delayed by something, otherwise he would have arrived earlier than me. ”

"When he arrives in Linshan City and investigates and understands everything clearly, our brothers don't have to live with their hearts and minds all day long, this is what it feels like...... It's uncomfortable. ”

Zhao Ting nodded in agreement.

Having a feud with an "ominous" hidden in the shadows and at least a third-order one, well, this taste is really uncomfortable, and I don't dare to close my eyes when I sleep, for fear that I will suddenly disappear before I wake up one day.

Thinking of this, Zhao Ting gradually clenched his fists, and a sense of powerlessness welled up in his mind.

To be honest, in the face of these monsters with strange abilities, bloodthirsty and cruel and weird, Zhao Ting really couldn't imagine that mortals could have the slightest way to live!

Silence, or silence.

After a while, Zhao Ting suddenly asked out loud: "Has anyone in the Spirit Clan tried to transplant the "Killing Crystal" in the "unknown" body into his own body?"

Zhao Tai was taken aback by his sudden question and said, "This is ...... Who would dare to try? Do you think you've lived too long?"

"In other words, no one has tried it?" Zhao Ting asked rhetorically.

"This ......" Zhao Tai hesitated at the sight of his burning eyes, "I can't guarantee that no one has tried, after all, there are so many crazy people in the world, but I really haven't heard of anyone daring to do this." ”

"After all, the Spirit Clan with a little common sense knows that after leaving the main body of the original residence, the killing crystal is a useless poison, who will transplant the poison into their own body?"

Zhao Ting didn't speak, but there was a thoughtful look on his face.

After about half an hour, Zhao Si pushed the door and walked in, hung his head and said: "Master, the weasels in the hands of the hunters have all been bought by us, no! The villain had no choice but to buy some voles." ”

Zhao Ting's face darkened, and after a moment, he said, "Vole, vole, take it in." ”

"Yes. ”

Looking at this litter of cute fat voles, Zhao Ting was in his heart: "......"

Speechless is speechless, clinical trials still have to be done. It's just that this cross-species "killing crystal" transplant, well, seems to be a bit hanging.

Putting on his "disinfection gloves", Zhao Ting instructed: "Zhao Si, you will record the survival time and clinical reaction of each vole after transplanting the killing crystals. ”

"Master, what is a clinical reaction?" Zhao Si asked weakly.

Zhao Ting said: "It is a series of physical changes that occur on the vole, no matter what the changes are, you have to record them." ”

"Oh, the villain knows. ”

"Bring me the hemp boiling powder I made. ”

"Yes. ”

Zhao Tai listened on the side, his face gradually becoming confused.

"Zero 07, survival time of half a quarter of an hour, clinical reaction is convulsions, eye rolling, mania, dilated pupils, ......"

"Zero 08, survival time is less than half an hour, clinical reaction is feigned death, mania, dilated pupils, ......"

"Zero 20, a quarter of an hour to live, clinical reaction is dancing, screaming, foaming at the mouth, ......"

......

Before I knew it, it was getting dark.

"Zero Seventy-Eight, Survival Time...... Well, he is still alive, and the clinical reaction is that the coat color is dark, the body is enlarged, the eye circles are red, and the obvious tendency to attack humans ......"
