"Dean Zhang" Ke Yirou looked at the old man and called out respectfully.

The old man put down his research, turned his head to look at Ke Yirou, and then said with a smile: "Little girl, why do you have time to come here with my old man today."

"Dean Zhang, I came to you today mainly because there is one thing to trouble you," Ke Yirou said.

Dean Zhang wiped his hands, took off his gloves, and asked, "What are you looking for me, tell me."

"He has the same powerful power as a genetic warrior, but he said that he is not a genetic warrior, but a so-called martial arts master, Dean Zhang, you can help draw blood for a test to see if he has any star beast cells in his body," Ke Yirou said.

Hearing Ke Yirou say this, Dean Zhang suddenly became interested, focused on Xu Ran's body, and said with a smile: "Young man, you are not a genetic warrior."

Xu Ran nodded.

"Come with me and check your body data," Dean Zhang said, and then beckoned to Xu Ran, who didn't know why, but still walked over.

Dean Zhang let Xu Ran walk into a transparent cabin that could only accommodate one person, looked at Xu Ran and said, "If you can't bear it for a while, just shoot the glass."

Xu Ran didn't understand what this meant, but nodded anyway.

After Xu Ran walked in, Dean Zhang closed a thick metal door in the glass cabin, then walked to the side of the operation station and pressed a green round button.

Snort!

Xu Ran, who was in the glass cabin, saw several cold breaths coming out of his head, and then felt the temperature in the glass cabin suddenly become colder.

A chilly breath appears, and the temperature begins to drop, then gets colder and colder.

Xu Ran frowned, felt the coldness, and with a thought, a layer of spiritual power covered his body, isolating the cold air around him, and he felt a lot better.

"It's minus 30 degrees, he doesn't seem to have anything abnormal" Outside, Dean Zhang said, the temperature on the glass cabin showed that the temperature inside was minus 30 degrees.

Ke Yirou stood next to him and watched quietly.

Subsequently, Dean Zhang continued to lower the temperature, from minus 30 degrees Celsius to minus 70 degrees.

Seeing that the other party didn't have any strange expression, Dean Zhang said lightly: "His body is cold-resistant, and he has surpassed the limits of the human body and reached the level of a genetic warrior."

Not to mention minus 70 degrees, even if it is minus 40 degrees, ordinary people can't bear it, maybe they can bear it, and it is estimated that they will tremble.

In severe cases, they will freeze into a vegetative state.

Now the other party is in a temperature of minus seventy degrees, and there is nothing to do, and it is obvious that the body is cold-resistant to the level of a genetic warrior.

The other party did not shoot the glass, and Dean Zhang continued to lower the temperature, from minus 70 degrees to minus 80 degrees, 90 degrees, and 100 degrees.

Dean Zhang frowned and said, "Girl, are you sure that this young man is not a genetic warrior, but a martial arts master, even if it is a folk health preservation method to strengthen the body, it is impossible to be so cold-resistant."

"I don't know, he said yes, and on the way here, a strange thing happened," Ke Yirou said exactly what happened when he came.

"It's really a bit weird," Dean Zhang frowned, and said, "I thought of a conjecture, that is, the power in his body has reached a saturated state, and he can release the power in his body to form something similar to an imaginary power shield to protect you."

After finishing speaking, Dean Zhang shook his head and said, "However, this is just our imagination, this kind of thing is only available on TV, and with our current scientific research, there has been no breakthrough."

Dean Zhang said as he lowered the temperature to minus 150 degrees, and then observed Xu Ran's situation in the glass cabin, and the other party still looked relaxed.

"Girl, you will soon be a fifth-level genetic warrior, it seems that you can only withstand the cold of minus 150 degrees," Dean Zhang said with a smile on the side.

"Yes, Dean Zhang" Ke Yi's soft face was slightly serious, "I fought with this person three days ago, and the strength of the other party is not much different from mine, and it is indeed able to withstand the cold of minus one hundred and fifty."

"Let's continue to lower it, I want to see where his limit is," Dean Zhang said with a smile.

Then from minus 150 degrees to minus 200 degrees, after waiting for ten minutes, the other party's expression was still flat, and he didn't feel any coldness.

At this time, the two people outside were not calm.

"Two hundred degrees below zero, it takes a level 5 genetic warrior to withstand it," Dean Zhang said.

A trace of doubt flashed on Ke Yi's pretty face, and he said, "A few days ago, I fought with him, and his strength was almost the same as mine without weapons, and in just a few days, he had reached the level of a fifth-level genetic warrior."

Ke Yirou's tone was a little shocked.

"It's okay, then I'm lowering it by 50 degrees," Dean Zhang said, and then lowered it from minus 200 degrees to minus 250 degrees.

"It's okay" Dean Zhang's eyes were about to pop out, and he exclaimed: "Girl, minus 250 degrees Celsius is cold-resistant, at least a six-star warrior can withstand it, and I don't believe he is not a genetic warrior if he is killed."

"He, why is his body so cold-resistant" Ke Yirou on the side also had a dumbfounded expression.

"Dean Zhang, do you want to continue to lower it?" After a pause, Ke Yirou asked sluggishly.

"There's no need," Dean Zhang said, "His physique is not estimated to be cold-resistant, and it's not interesting to test it, so let's try his body's high temperature resistance."

Dean Zhang said, and then tested Xu Ran's body's high temperature resistance, and pressed the red round button next to him, at the same time, Xu Ran in the glass cabin felt that the temperature inside began to heat up from cold, and then became hotter and hotter.

In desperation, he could only urge a thick layer of spiritual power to wrap his body layer by layer as before.

"The temperature inside is three hundred, and the other party is still fine" Outside, Dean Zhang, Ke Yirou looked at the temperature display dumbfounded, the high temperature inside was three hundred degrees, and the other party was still fine.

"Forget it, there's no need to test it, whether it's cold or heat resistance, his physical fitness has at least reached the physical fitness of a sixth-level genetic warrior," Dean Zhang said, turned off the instrument, and then released Xu Ran.

"Young man, I'm pretty sure you're a genetic warrior now, and at least a sixth-level genetic warrior" As soon as he opened the hatch, Dean Zhang looked at Xu Ran and said with a swear.

Xu Ran touched his nose and said quite innocently: "I said it all, I'm not a genetic warrior."

"Hmph, then I'll take blood for testing" Dean Zhang sneered twice, then took a tube of Xu Ran's blood, and said confidently: "Give me half an hour in the world, and I will be able to test the genes of which star beast is in your body."
