Luo Chen directly skipped the introduction of the nonsense source on the enhancer, and focused on confirming the effect of the reinforcer named KW74.

Directly strengthen the human body's functions, greatly improve the reaction speed and strength, because the agent will produce great pain when acting on the body, the specific effect depends on the strength of the individual's will, the longer the persistence, the stronger the effect.

Once the limit of one's willpower is exceeded, it is very likely to directly cause brain function trauma and become dementia. In terms of description, there is a standard that the average soldier can only withstand for half an hour at most.

Luo Chen felt that the side effects of this booster were far less simple than those explained above, I am afraid that there was not only a risk of becoming dementia, but it was more likely to be direct brain death, although there was not much difference between the two in his eyes.

As far as he saw the original book, the existence of the intensifier was mentioned more than once, and in a temporary underground military base in the southern district of H City, there seemed to be a more stable and less dangerous reinforcer.

The problem is that Luo Chen doesn't know where the underground base is now, and even if he finds that place, why should people use it for him. And he always felt that while this potion became safe, it also limited its upper limit.

Luo Chen glanced at the list price of 70,000RMB, and there was a Z8 machete worth 8,888RMB. Not to mention whether the included knife is worth so much money, as long as you think about the source of this reinforcer, this price is almost the same as the price of cabbage.

Luo Chen clicked to put it in the shopping cart, and then added equipment such as night vision devices, strong flashlights, and alloy military spurs. Finally, he looked at Su Shan and said, "Give me Lao Chen's bank account number and password." ”

Su Shan glanced at Lao Chen, and saw that his face seemed to be a little unnatural, and immediately happily told Luo Chen about the account and password.

Luo Chen entered the account and password, checked the balance, and suddenly showed surprise on his face, and said with a smile: "730,000 RMB, Lao Chen, your net worth is rich enough." ”

Lao Chen said angrily: "It's all my coffin book!" ”

Zhao Youyou spoke at this time: "By the way, settle my salary." ”

Luo Chen turned his gaze to her: "Report your account number and password as well." ”

Zhao Youyou: "......?" ”

The expression of her small face did not change in the slightest, but her straight chest continued to rise and fall, and it was obviously not as calm as it appeared to be.

She only remembered now that this guy was still a robber.

Under Luo Chen's muzzle gaze, it took her half a minute before she reported her account number and password.

"Only 50,000?" Luo Chen shook his head, and finally turned his gaze to Su Shan.

Su Shan hurriedly shook his head: "I don't have any money, if I have money, I don't have to do this!" ”

"Whose Raptor belongs to that outside?" Luo Chen asked.

The big V8 self-priming that landed 600,000 or 700,000 is not a few people willing to buy it.

Su Shan scratched his head and said with a smile: "That's the car I stole yesterday." ”

Luo Chen shook his head speechlessly, but 780,000 yuan, which is not a lot.

He directly increased the number of boosters to 11 in the shopping cart, and then found that there was a buy 10 get 1 free discount, so that 770,000 yuan could buy 12 sticks.

Together with the other things in the shopping cart, Luochen directly clicked to buy them all.

Finally, the customer service prompted that it would be received on the roof of the supermarket after 12 hours.

Luo Chen remembered that the original book seemed to be delivered by helicopter, and this merchant was good enough.

The reason why he bought so many boosters was because Luo Chen remembered that this thing could be used in stacks, but the effect of using it later was not as significant as the first time.

If there is only one sip, it is obviously impossible to strengthen all the genes in the whole body by forcibly interrupting the strengthening process with an inhibitor on the premise of taking into account the individual's ability to bear it. Therefore, it is possible to continue to strengthen the remaining genes later.

Of course, there are so many upper limits on the human body and the reinforcer, it is impossible to strengthen it indefinitely, and it is estimated that after using it three or four times, there will be no more strengthening effect.

Luo Chen looked at Su Shan and the three of them and said, "Due to visual limitations, it is impossible for zombies to move frequently at night, and in general, it will be safer at night."

The real danger is during the day.

But we can't relax because of this, the four of us take turns to keep vigil, in groups of two, Su Shan and Lao Chen in the first half of the night, and I and Youyou in the second half of the night. ”

The problem is that in one night, the devil knows how far these 'corpse brothers' will devour and mutate. At that time, even if Luo Chen's strengthening is successful, I don't know if he has confidence.

Let Su Shan and Lao Chen team up because these two have old grudges, and the possibility of them joining forces to make trouble can be ruled out to the greatest extent.

"In addition, always pay attention to the outside monitoring, ordinary zombies don't care, if there are any mutated monsters, immediately shout a warning.

There are ordinary people who come to ask for help, and they don't see it.

Put away your kindness, and you must understand that we are not qualified to save anyone. Every time you save someone, it is equivalent to pushing everyone further towards the ghost gate. ”

Fortunately, none of the people present were fools or virgins.

Otherwise, Luo Chen wouldn't have the courage to stay with them. At the moment of life and death, even if they have compassion, they should be able to ignore it in front of their own lives.

Even if Su Shan, whose brain turns slowly, is not an absolute bad person, nor is he a good person, it is impossible to sacrifice himself to be so noble.

Before resting, Luo Chen took a look at the mechanical watch in his hand, the time display - 03:25, and the task time had passed three and a half hours.

……

The next day, early in the morning.

The sun swayed the earth, and a helicopter appeared on time over the roof of the supermarket, and after seeing Luo Chen, he directly dropped a parachute.

Regardless of whether the parachute would fall outside the rooftop, the helicopter simply flew away. Fortunately, the parachute finally landed on the edge of the rooftop without any danger.

Luo Chen unfastened his parachute and picked up the box. He didn't immediately go downstairs, but stood on the edge of the rooftop and observed the city.

The situation seems to be even worse than he imagined.

It was as if the whole city had become a 'corpse brother' overnight.

Looking down from the sky, there are at least hundreds of 'corpse brothers' on a street.

He had even seen quite a few strange-looking mutated 'corpse brothers' appear.

Suddenly—

His face suddenly turned ugly.

As far as the eye can see, at least 1 kilometer away, a huge, indescribable 'corpse brother' is rampant in the city, like all kinds of messy insect limbs spliced together, but there are also human faces and tentacles.

Luo Chen saw with his own eyes that it crushed a small three-story building into ruins.

For a moment, Luo Chen's mood was heavy and at the same time more urgent.

Hurriedly descended from the rooftop, locked the iron gate of the roof, and then blocked it with a steel pipe.

"Don't bother me for an hour!"

Zhao Youyou and the three of them saw Luo Chen's serious interview, and immediately looked at each other.

On the second floor, lock the room, Luo Chen unlocked the box, first put aside the night vision device and other equipment and the 12 Z8 machetes he gave away, and then took out twelve alloy boxes, opened one of them, and put all the others away.

Inside the box are two tubes of medicine, one gold and one blue, with their own syringes.

An instruction manual is also included.

Luo Chen picked up the instructions and looked at them, and as he expected, the actual side effects of this potion were far worse than advertised.

The gold syringe is the booster and the blue cannula is the inhibitor.

The reinforcing agent in the golden syringe needs to be injected directly into the heart before the strengthening action is activated. The process is extremely painful, but the longer it endures, the greater the effect. Then, when you feel that you can't support it anymore, you will insert the blue needle into the heart to neutralize the power of the booster.

However, only after 5 minutes of injection of the booster, the effect of the drug will take effect to strengthen the gene, and it will last less than 5 minutes, which is not as effective as it is at all. However, it should not exceed 50 minutes, and the inhibitor must be injected within 50 minutes, otherwise it will explode and die.

Luo Chen couldn't guess what kind of state the so-called 'exploded body died'.

Anyway, it's definitely going to die.

The most indispensable thing in Luo Chen's character is decisiveness.

Moreover, even if he dies, it does not mean that he dies in reality.

Although, he also suspected that the system was lying to him.

Keep the pistol you carry with you properly to prevent it from misfiring.

He took out the timer he had brought from downstairs and pressed the timer switch.

Then he picked up the golden syringe and pricked it in the heart without hesitation.

Injection!

In an instant—

"Ahh

Pain! Pain! Pain! Pain, pain, pain!!

Luo Chen, for the first time since he was born, has experienced the heart-rending pain in the true sense of his body.

It was as if my heart was about to be torn apart!

The nerves of the whole body are beating wildly!

The tendons and tendons seem to be about to be torn off!

Every cell in my body seems to explode!

How he longed for himself to faint.

He even suddenly regretted why he had injected it.

He spent the first 20 years living in a modern civilized world like a greenhouse.

Reality can't be as easy as a few pages in a comic.

He thought it would be as thrilling as Bai Xiaofei.

He overestimated his endurance.

The face was distorted and ugly, and snot and tears were mixed together.

The body twitches, writhes, struggles meaninglessly on the ground.

"Ahh "Ahh

"Ahh

He began to pound his head against the ground, and the outside stimulus seemed to make him feel better, and his brain began to regain a bit of clarity.

The heart beats so fast that it is definitely beyond the normal limit of ordinary people.

Blood, mixed with snot, tears, sweat on his face.

The huge movement had already alarmed the three of Zhao Youyou downstairs last time, but they remembered Luo Chen's warning and stopped the urge to open the door.

However, Luo Chen's ghost-like howl made them chill inexplicably.

Pain hit Luo Chen's brain like waves, and his consciousness began to blur, which made him feel bad.

He picked up an awl that had been prepared in advance along with the timer.

Pierced on the thigh!

"Ahh

Outside stimulation diluted his numbness. Consciousness quickly returned to concentration, and he looked at the timer and realized that only 11 minutes had passed.

After 5 minutes, the potion has begun to work.

However, Luo Chen was not satisfied.

At some point, his eyes turned golden.

There was a flicker of ruthlessness and madness.

Perhaps he himself did not know that there was a kind of paranoia that bordered on madness hidden in his personality. The more impossible things are, the easier it is to make him extreme.

The pain inside his body did not diminish in the slightest, and instead of becoming numb, Luo Chen's nerves became more acute, constantly magnifying his pain.

His tongue was about to be bitten off, and blood was running down his chin. I don't know how many knives I have stabbed in my thigh, and the ground is bloody.

He tried his best to keep himself awake, and if he passed out, he would surely die.

Maybe even he didn't expect that his willpower could be so strong.

Minutes and seconds passed......
