After leaving the Xingguang Pharmaceutical Building, Chen Zai quickly rushed back to his home in the shantytown.

At this time, it was already the second half of the night, and there were not many people in the whole shantytown, and at this time, there was no light at all, and it seemed extremely quiet.

Chen Zai closed the door, the whole person was not sleepy at all, turned on the room light, and prepared to study the changes in his body.

From Ye Xintong's mouth, Chen Zai knew that the abnormalities in his body should be due to macrophages, and the strength of macrophages in his body was more than a million times that of ordinary people.

Macrophages are part of the human body's immune system, a link, can effectively engulf pathogens entering the body, but after macrophages are enhanced to a million times that of ordinary people, what kind of effect will be produced, and how strong the phagocytic effect is, no one knows, to be tested by Chen Zheng now.

In Ye Xintong's laboratory before, those instruments inserted into Chen Zao's body were inexplicably corroded and dissolved, Ye Xintong suspected that they were devoured by the macrophages in Chen Zao's body, but there was no absolute evidence, and Chen Zao wanted to confirm this at this time.

He began to try......

An hour later, Chen's attempt stopped.

There was shock, excitement, and regret in his eyes......

What shocked him was that his body could indeed devour foreign substances now, and the devouring effect was so strong that it simply made Chen Zai stunned and amazed.

Chen Zai had tried to cut his own flesh with an alloy dagger, which he had obtained from the corpse of a top-notch mercenary, so sharp and indestructible that even cutting steel was like cutting tofu, even if it was soaked in the strongest aqua regia, there was no response.

But the moment the alloy dagger cut through the flesh and blood, Chen Zai found that the alloy dagger was corroded!

In just a few seconds, the part of the alloy dagger that touched Chen Zao's flesh and blood completely disappeared, disappearing out of thin air, and the qi in Chen Zao's body also increased by a point.

After that, Chen Zai tried many other materials, and without accident, they were all devoured.

It was as if there were countless insects with terrifying devouring abilities hidden in the flesh and blood of Chen Zheng's body, and anything that came into contact with it would be devoured.

And what he was excited about was naturally because this devouring would increase the qi in his body.

Chen Zai didn't know how this conversion worked, and why no matter what matter was swallowed, it turned into qi, but it didn't matter.

As long as the qi can grow, it would be good!

Because of the previous qi, it is too difficult to grow.

Although up to now, Chen Zai didn't know how to use these qi except to use Qi to treat Old Man Lin and help Chiba get through the medicine quenching.

It seems that Qi has not helped him much to improve his strength, and he is still fighting with his body to this day.

However, Chen Zheng secretly felt that qi was very important, and he couldn't use qi to fight now, just because the amount of qi was still too small.

He felt that when the qi in his body had accumulated enough, it would be the time for his strength to skyrocket again.

His secret feeling, maybe at that time, he can be regarded as truly invincible!

Qi may be the key to his next evolution!

Chen Zheng has now obtained the first three parts of the innate power, and he has also used his mind to simulate the cultivation, but the first three parts of the innate power have been successfully cultivated, and he cannot cultivate the qi.

Therefore, whether it is Han Su, Master Wang and others, although they practice qigong and consider themselves qi practitioners, in fact, they are just masters whose bodies are stronger than ordinary people, and in their bodies, there is not the slightest bit of qi.

Chen Zai guessed that perhaps the fourth or fifth part of the innate gong could be cultivated successfully, and it would be possible to generate qi in the body, but it could also be extremely rare.

In short, the rarity and importance of the 'qi' in the body is probably much more important than Chen Zai imagined.

And now, in addition to using the cultivation of nameless qigong to increase qi, Chen Zheng has another way to increase qi, how can this not make him excited?

But unfortunately, this kind of growth and improvement is too rare and slow.

"Even if I desperately stick a knife into myself every day, let the flesh devour them and transform them into qi, I'm afraid that if I persist for a year, I may not be able to increase my qi by one-tenth ......"

Chen Zai calculated the speed of the ascension, and couldn't help but be a little speechless.

Naturally, it is impossible for him to cut his own flesh and blood every day and devour all kinds of substances, just to raise a little bit of qi, which is not to be scared to death if he is discovered.

Of course, Chen Zheng can also use the way of 'eating'.

Whatever is swallowed in the stomach is considered by macrophages to be harmful to the body, it will also be swallowed and quickly converted into qi.

In other words, as long as Chen Zheng eats all kinds of poisons, not only will he be fine, but he will also improve his strength.

But this improvement is still too slow to be worth it.

"It's a pity, I thought I had found a way to quickly improve my strength, but it turned out to be like this, and sure enough, there is no such good thing in the world......"

Chen Zai muttered.

In general, this time the physical mutation, in addition to making him invulnerable, did not bring him a substantial increase in strength, at most it was a little more weird.

Of course, Chen Zheng has only studied it briefly now, and what will happen in the future needs to be studied slowly.

Chen Zai turned off the light in his room and prepared to take a break.

Before helping Chiba get through the medicine quenching, he had almost exhausted the qi and spirit in his body, and then he fought several battles with Chiba, and then went to verify Ye Xintong's experiment, and came back to study the mutation of the body, Chen Zheng was already sleepy, but his strong willpower was just supporting it.

After lying down, Chen Zai quickly fell asleep.

I don't know how long I slept, Chen Zai suddenly felt a palpitation and opened his eyes suddenly.

He didn't think about it, he turned over and got up and flashed to the position behind the door, the whole movement was light and fast, like a tanuki in the night, without making a sound.

At the same time, Chen Zao felt two slight breathing sounds, which were slowly approaching him.

It's close!

A faint killing intent shrouded the top of Chen Zheng's head.

Chen Zai's face was cold, and the whole person seemed to melt into the darkness, standing motionless behind the door, feeling the two people in the living room, and slowly touched it.

The next second, the door was slammed open.

Two emaciated figures rushed up, raised their hands and shot directly.

Puff puff!

After being silenced, the bullet quickly covered Chen Zai's entire bed, covering every corner, and suddenly cotton wool flew and was a mess.

If Chen Zheng hadn't woken up in advance, I'm afraid he would have been shot into a sieve at this time.

It's a pity that Chen Zai was not on the bed at this time, but behind the door, and he didn't move when the two killers started shooting, and when the bullets in the two guns ran out, Chen Zai suddenly moved.

He slammed out from behind the door, kicking a killer in the chest.

The killer originally thought that Chen Zai had died in bed, but he didn't expect that Chen Zai would suddenly flash out from behind the door, and he immediately didn't react, and was directly kicked by Chen Zao.

The force of Chen Zai's kick was so great that he immediately kicked his whole person out of the air, and directly spurted out a mouthful of thick blood.

This is still Chen Zai who wants to spare his life, and he didn't use all his strength, otherwise if he goes down, Chen Zai will have the confidence to directly kick all his sternum off, and all his internal organs will be shattered and he will die.

But even so, the killer fell to the ground, lost his ability to move, and the whole person was pumping.

At this time, another killer reacted, he had a frightened look on his face, and a second gun quickly appeared in his hand, shooting at Chen Zao at close range.

Chen Zai sneered, and as soon as the killer's hand was raised, a knife fell and immediately slashed at the killer's wrist.

Only a crisp click was heard, and the front half of the killer's arm drooped down and folded into a ninety-degree right angle.

Sharp broken bones pierced the flesh, and blood flowed.

And the killer's finger no longer has the strength to pull the trigger, not to mention that even if the trigger is pulled, he can only shoot on the ground at this time.

The intense pain of the broken arm made the killer want to scream violently, but he was also a ruthless man, and he actually endured it alive, and with his other hand, he quickly took out a dagger and slashed at Chen Zheng's neck.

But in the next second, he only had one hand, and he was also slashed by Chen Zai's hand knife, and it was immediately broken from the middle.

At this moment, the killer couldn't bear the intense pain anymore, and he was about to scream loudly when he opened his mouth, but before he could shout, the whole person had already been kicked out by Chen Zheng and hit the wall and fainted directly.

In the blink of an eye, the two killers lost their ability to fight.

The killer, the strongest is the moment of the sneak attack, when their sneak attack was discovered by Chen Zheng in advance, the result after that has already been determined by itself.

In terms of frontal fighting ability, if there are ten times more killers, Chen Zheng is not stunned at all.

Chen Zai looked at the two killers who fell to the ground, and he didn't have to think about it at all, he knew that they were all killers on the black list, and their level would not be very low.

At least it's a gold-level or above, or even a platinum-level blacklist killer.

Who wants him dead?

Chen Zai instantly thought of King Li!

When King Li was dying, he once said that he had a revenge fund, and once Chen Zheng killed him, the revenge fund would immediately run and hire the best killers to avenge him.

He originally wanted to let Chen Zai let him live, but Chen Zai didn't pay attention to it at all and killed him directly.

And now that these two killers appeared, Chen Zai felt that it was likely to be related to King Li, and it might be that King Li's revenge fund was running.

Thinking of this possibility, Chen Zheng suddenly frowned.

He didn't know how big the Force's revenge fund was, and if it was big enough, he was afraid that countless top killers would rush to kill him.

But these are just speculations, if you want to confirm it, just ask these two killers.

Chen Zheng spared their lives just to torture them.

One of the killers had already fainted with his hands broken, and when Chen Zai turned on the light, he found that the other killer was looking at him with a frightened face, his body trembling, and his face was pale.

Although he did not faint, he also broke several ribs, and his internal organs were all shattered, and he endured great pain.

If he didn't go to the hospital for treatment earlier, it would be a question of whether he would be able to survive.

Chen Zai looked at him coldly and said calmly: "Say, why did you come to kill me?" I will only give you one chance to speak, if you are not willing to speak, then you will never speak." ”
