Cillin's nose is very smart, and he can separate and parse the mixed breath he smells, and because of this, Cillin is surprised.

People who use these kinds of reagents, is it idle egg pain, interest in research or other reasons?

The smell did not come in from the rain outside, but from the wind direction and the air currents, it could be judged that the smell was wafting from the inside of the building. But who would use those ancient reagents in such an abandoned building? Or rather, in this day and age, who else but the R&D department of some quirks would use that primitive approach?

Searching for the scent, Cillin found a thumb-thick pipe in a push of waste, and after walking along the pipe, he found that the part behind the pipe was hidden in the wall.

It's really well hidden.

When you open the finger-sized close-up projection tube, a pale blue light shines on the wall, and the pipes buried in the wall are clearly visible. After checking it out, Xilin became more and more curious.

Interesting.

In addition to this pipeline, Xilin found several more places, all of which were hidden.

Cillin became more and more cautious, and although it was the best option to leave the place now, Cillin had a strange feeling that prompted him to desperately want to find the reason.

Going down the pipe, going through twists and turns, a few of them still required Xilin to climb in through the ancient vents. Arriving on the first floor of the building, Cillin lifted a hidden lid and walked down the narrow staircase below.

It was quiet, but not completely. After feeling it carefully, he felt that there was no one within a short distance, so Xilin took the light tube and continued to walk inside.

There are more and more pipes, Xilin knows that he is getting closer and closer to the target, takes a deep breath, and turns off the light tube, although he didn't feel that there is someone in front of him, but his intuition tells him that the front will not be so smooth, although the energy fluctuation generated by the light tube is only within ten meters, but for the sake of insurance, Xi Lin decisively turned it off.

It was pitch black all around, and Cillin relied on the subtle movement of air to determine direction and avoid obstacles. After about half an hour, the surrounding space gradually became larger, and some electronic lights the size of fingernails also appeared, and through the bright light, it was clear that this place has been around for a while. And there is dust on the electronic light board, although it is not thick, but at least no one will walk from here for a month.

Looking at the spots of light on the wall, Xilin became more and more uneasy.

Something is wrong, something is very wrong! It's like ...... Pitfall! A trap!

A strong sense of crisis hit, Xilin didn't think much about it, turned around and ran back. As a hunter's intuition, he had no way to deal with the dangers that might arise next.

But what is faster than Xilin is the thick special steel plate that blocks the retreat.

A metal knife appeared in Xilin's hand, although the steel plate could be cut with a laser knife, but it took a lot of wasted time, and second, the strong energy fluctuations of the laser knife also exposed Xilin's position at all times.

With his back against the steel plate, Xilin quietly looked ahead, he knew that there must be someone in front.

Da, da, da......

The footsteps came this way unhurriedly, without the intention of concealing at all, but with a fearless attitude.

Click.

A beam of light shone on, and the passage suddenly lit up.

Cillin squinted, quickly recovering from the discomfort of low to strong light. But the person standing opposite didn't seem to be in a hurry, waiting for Xilin to recover.

It was an old man, who looked about the same as a person of the F-class genotype who was nearly 100 years old, and felt like he was going to be buried at any moment. The old man's skin was brownish, his body was shriveled, and his exposed arms showed muscle atrophy, because the old man was wearing a goggles, and Cillin couldn't see his eyes clearly. But it was the shriveled old man in front of him that made Xilin feel cold and trembling all over his body.

The old man walked slowly towards Xilin, leisurely as if he were walking.

Strike first!

Xilin swooped up, and there was not even an afterimage left, which showed that his speed was so fast, and he was not weaker than a person with D-class genes.

Boom!

A screeching metal sound rang out.

Next to the old man's carotid artery, a withered hand firmly grasped the tip of the knife, as simple as pinching a branch.

Whether it is an ion knife or a laser knife, the energy fluctuations generated are too large, and with Xilin's current physical fitness, the chance of exposing himself is greater, so Xilin is more willing to use cold weapons to kill people in silence. But even such a special alloy blade was easily blocked by the old man in front of him who seemed to be about to enter the ground, no, it should be said that it was easily pinched!

The hunter experience between life and death for three years made Xilin have no time to think about it, the person in front of him is not something he can deal with, escape!

But before Xilin could make a move, his body was suddenly firmly bound by something like liquid metal. Looking at the source of those things, Xilin was stunned to find that this piece of liquid metal-like thing actually came out of the five fingers of the old man's other hand, to be exact, it was an extension of the old man's five fingers!

Mankind? Machine? Mutation? Or is it some unknown species?

Cold to the touch, Xilin smelled the breath of death, and every pore breathed cold breath.

Click!

The alloy dagger, which had taken the lives of many wanted criminals, was crushed. The old man's thin fingers grabbed Xilin's neck, twisted Xilin like a chicken, and lifted Xilin off the ground.

All limbs were tied, and the blood vessels in the neck were almost blocked.

"Hehe, you're here at the right time." Listening to the voice, the old man seemed to be very happy, even a little impatient.

If ordinary people were pinched like this, they would have started to roll their eyes a long time ago, but Xilin still had the strength to think about countermeasures.

The old man looked at Xilin and was even more satisfied.

One door after another, one door after another, Xilin became more and more frightened, in this slum town, there was such a place hidden!

This underground secret room is by no means more than thirty or fifty years, and it is far more complicated than Xilin imagined, both in terms of protection and concealment, it is extremely well done, otherwise it would not have been discovered for so many years, or the people who found it would have died.

Cillin glanced at an open room, full of people who had been kept in liquid tanks like specimens, and the distorted expressions on their faces made Sillin shudder, and it was obvious that these people had endured unbearable torture before they died.

Perhaps, the next moment, Xilinbian will become one of them.

The old man did not mean to put Xilin to death immediately, and the strength in his hand was well controlled, which would neither give Xilin a chance to escape, nor would Xilin's physical function be damaged.

The reason why the old man said that Xilin came at the right time was because as soon as the previous experimental subject died and was put into the liquid tank, Xilin was sent to the door.

Cillin was taken to a room full of instruments and tools, and on a table in one corner of the room were many bottles and jars, several of which Cillin had identified from the gas expelled from the pipes, and these were reagents for purifying DNA.

In this era, except for the old pedants, almost no one uses or understands the primitive method of purifying DNA. Cillin had done a similar experiment, but it was just out of curiosity and did not conduct in-depth research.

Purifying DNA, with today's technology, requires only a palm-sized instrument, fast, precise, and functional analysis of the genome. However, no matter what kind of purification analytical instrument is required, real-name authentication and registration are required, and each instrument has a registration code, chip binding and data connection.

Since the old man chose to purify by hand, and looking at the posture or purifying in large quantities, it means that this person is engaged in illegal research and is going to be wanted, but Xilin searched for the wanted information in his mind and did not find any information about the person in front of him, the wanted list of the planet, regardless of the degree of danger, is public, and there are only two pieces of information on the wanted warrant, one is a picture, and the other is the amount of reward.

Because this laboratory is underground, and it is also paved with a rare isotope partition layer, it has not been discovered by the "eye of the sky", and the instrument data of the laboratory should not be connected to the outside world, which avoids other explorations.

What is this old man going to do?

Put Xilin on a suspended white table, the old man pressed the button on an instrument next to him, Xilin's wrists and limbs were buckled by the cuffs that came out of the table, and thin silk threads emerged from the table, and penetrated into Xilin's body through his clothes and pants, instantly turning Xilin into an experimental subject full of wires, with red filaments on one side and blue filaments on the other, and the data on the monitor next to him kept beating.

Since Xilin had been bound by the things on the stage, and he didn't even let go of his fingers, the old man withdrew his hand, and his fingers returned to their original dry branches, and after injecting Xilin with a tube of slimy cold liquid-like things, he quickly pressed the button on the instrument to combine and analyze the data on more than ten other instruments.

The pain, the pain that penetrated into the bone marrow, the fingers trembled, the blood in the whole body was flowing irregularly, every moment was challenging the limits of the nerves, and the thinking was almost instantaneously scattered, but after a short blank period, Xilin finally re-thought and concentrated a little bit, otherwise, it would not be long before Xinlin himself would become one of those specimens.

Those slimy liquid-like things are actually tiny special biochips, some of which are very similar to gene vectors, and can be integrated into the chromosomes in the human body to replicate and divide simultaneously.

The red filamentary tube is mainly induced, providing nutrients and inducing the metabolism of the main body, so that the cell division is accelerated, while the blue filamentary tube is mainly apoptosis, allowing those backward cells that cannot keep up with the progress to die.

The old man stared at a rising wave crest on the frequency curtain, laughed a few times, and rotated the knob at hand ten degrees clockwise, and the degree of induction rose by one stage every ten degrees, and the degree of excitation of the chip also increased accordingly.

The changes in the hippocampus, methylated regions on chromosomes, and the frequency of communication between cells in the brain are displayed in the form of data on a constantly flickering screen, which excites the elderly.

Cillin's nerves were hit again by a greater pain, and then he struggled to gather his spirit.

"It's not simple, it's not simple, just F-level genotype, it can be done to such an extent!" Looking at the knob, which had been rotated one hundred and eighty degrees, the old man began to talk to himself, but there was obvious excitement in his words.

One hundred and eighty degrees, proving that those chips have been activated by fifty percent, and now this person is still alive, and the data flashing on the screen makes the old man's voice tremble a little. In the previous experiments, less than half of the people were able to survive 180 degrees, indicating that the body of a person with this F-class genotype is comparable to that of a D-class.

But how long will it last? If you hold on for ten degrees more, there will be an extra set of data that makes the old man excited, but the old man doesn't care about Xilin's life and death.

Cillin searched for an escape amid the constant blast of pain.
