The next day, early in the morning.

In the park that Luo Chen and Zhao Youyou passed through before, a triangular head suddenly appeared from the remaining hole in the ground, and a 'rat-shaped corpse brother' came out of the hole, it smelled the pungent smell of blood in the air, and let out an excited cry.

Immediately afterward, the pits on the ground continued to drill out of its kind, and soon more than a dozen 'rat-shaped corpse brothers' appeared on the ground.

They spotted the corpses of their kind not far away, and immediately rushed to run over, gnawed at the corpses of their kind, and quickly devoured them.

One of the 'rat-shaped corpse brothers' was particularly strange that he hadn't gone with the rest of his companions to gnaw on the corpse. Compared to other counterparts, its head is not covered with helmet-like bones, except that its nose is very large.

Its large nose fluttered in the air, then scurried around the exit of the park, before finally stopping and barking at its companions.

"Squeak~squeak~!"

All of its companions looked at it and made the same "squeak" sound, as if exchanging information. Soon, they were lined up in a column under the head of that big nose.

Led by the big-nosed 'Rat Corpse Brother', all the 'Rat Corpse Brothers' are traveling in one direction. That direction was the direction in which Luo Chen and the others left last night.

……

Sunshine Hospital.

Luo Chen looked at the mechanical watch again.

56∶45

There are almost 15 hours left to get out.

↓ is displayed in the system status bar

Fine: 45

Gas: 0

God: 16

Lifespan: 21/68

Combat power: 24

Experience points: 161

The effect of the third booster had already been absorbed by the body, and Luo Chen felt that if he used it again, it might not have any effect.

Compared to his current state after the first enhancement, his 'Jing' has increased by 13 points, 'God' has increased by 1 point, his lifespan has increased by 3 years, and his combat power index has increased by 9 points.

It seems that the sum of the last two enhancements is not as large as the first one, but you must know that there are so many genes in Luo Chen's body, and the three enhancements have almost strengthened the genes in his body.

If you want to continue to strengthen, you can't be strong.

His current level should be equal to the limit that ordinary people can reach.

If you want to continue to become stronger, you may really have to rely on things like 'God's Genes' to evolve your life level and expand your potential.

Luo Chen suddenly thought that the 'God Gene' was extracted from the zombie virus, and the source of the zombie virus was the water source contaminated by the 'Corpse King', did that mean that the life level of the 'Corpse King' had been raised to the height that ordinary humans needed to look up to.

In addition, he also remembered that there seemed to be such a thing as martial arts in the original book, and the level of cultivators seemed to have reached an extremely high level, did it mean that human beings could also raise their own life level or expand their potential by relying on cultivation.

Back to the 5th floor, Lab 507.

Luo Chen saw Su Shan and Professor Mu, although the four of them had not slept all night, but compared to Luo Chen and Zhao Youyou, the two strengthened people, Su Shan and Professor Mu could obviously feel that they were not in a good state.

"This is what you want." Professor Mu tossed a notebook to Luo Chen.

Luo Chen opened it and looked at it a few times, nodded, and didn't say anything more. The current environment can't allow him to confirm the authenticity of this thing, so he can only wait until he returns to the real world and find someone to verify it again.

However, just in case, Luo Chen still decided to memorize all the things on it. Fortunately, even his brain has been strengthened, and his memory has been greatly enhanced.

"I've done everything you asked me to do, can I leave?" Professor Mu looked at Luo Chen, still a little worried that the other party would backtrack.

Luo Chen put away the notebook and said with a smile: "Don't worry, I won't regret it, where do you want to go now, please take care of yourself." ”

Luo Chen didn't need to self-destruct his promise, killing Professor Mu would not do him any good, and even if the other party wanted to retaliate against him in the future, he was afraid that he would not be able to find his people.

In fact, Luo Chen has not killed anyone so far.

It's not that you don't dare, but it's a question of whether it's necessary.

Luo Chen's statement made Professor Mu feel relieved.

He didn't want to stay any longer in the hospital, the power supply was cut off by Luo Chen, and he couldn't continue to do research here, and the transformed 'corpse brother' he controlled was also killed, and now he doesn't even have the ability to defend himself.

It's just that for a while, he doesn't know where to find a suitable research environment, and besides, there are many of his research materials and achievements in Sunshine Hospital, and if he wants to move them all, he can hardly do it alone.

Thinking of this, he felt even more resentful of Luo Chen in his heart.

Suddenly, his eyes fell on Luo Chen, and a thought popped into his mind.

Professor Mu spoke, "What are your plans next?" ”

Luo Chen looked at him and said with a smile, "What's the problem?" ”

Professor Mu affirmed his thoughts in his heart, and his smile was a little obscene: "You shouldn't have the next action goal, right?" Instead of being blind, cooperate with me, you keep me safe, and I make you stronger!

The end times are only going to get more and more dangerous, I can study the 'God Gene' in a few days, and if I am given more time, I can research even greater results! Believe me, you will follow me to become the gods of this world! ”

Professor Mu was indeed not joking, and sincerely hoped that Luo Chen would cooperate with him, but the result must be that he turned Luo Chen into his own transformed puppet.

Su Shan's eyes on the side rolled, quite moved.

However, when he saw Luo Chen, he knew that Professor Mu's goal was not his own at all, and it was pointless for him to agree.

Zhao Youyou's small face was expressionless, and his eyes were cold, making it impossible to guess her thoughts. However, Su Shan estimated that this girl must obey Luo Chen's orders.

Luo Chen had a smile on his face, Professor Mu's proposal looked tempting, but if it was really so simple, Professor Mu was not Professor Mu.

Underestimate these mad scientists who can turn the world upside down with their brains, and most of them will end up eating to the bone. Because you never know what he's going to work out of your control.

"I refuse." Luo Chen said.

Professor Mu's face gradually stiffened, and finally he snorted coldly in extreme discomfort.

……

After that, Luo Chen didn't care about Professor Mu, found a place alone, and spent more than three hours memorizing the materials of the improved KW74 booster completed by Professor Mu.

It was noon, and there were still 12 hours left before the disengagement time.

Luo Chen had eaten a lunch of beef jerky and bread, stood on the fifth floor of the hospital and looked out, and could not find the shadow of a 'corpse brother' as far as he could see.

It's so quiet and peaceful that it's almost eerie.

Luo Chen found Zhao Youyou and handed her three sets of strengtheners: "This is what I said before, you should be cautious by yourself in the future, I wish you good luck." ”

Zhao Youyou took the three alloy boxes and said, "You're leaving?" ”

In fact, since last night, she has been vaguely guessing.

Luo Chen didn't have the need to hide it, and nodded.

Zhao Youyou was silent, didn't ask for a reason, and didn't seem to know what to say.

Luo Chen vaguely sensed something, but he didn't think it made sense.

"Ahh

Bang! Bang bang bang!!

Sudden screams and gunshots broke the silence.

Luo Chen and Zhao Youyou's faces changed in unison.

This voice is Su Shan! He seemed to have been fooled by Professor Mu to help pack up the materials, in the 507 laboratory.

Luo Chen stepped onto his backpack, picked up the Mo knife, took out a pistol with his other hand, opened the safe, and took the lead towards the end of the corridor where the voice came.

Zhao Youyou stuffed three alloy boxes containing reinforcing agents into his backpack, then hung the backpack with two machetes behind his back, holding an automatic rifle in his hand, and then followed.

Before they reached the laboratory, Su Shan and Professor Mu had already run out in a hurry. Professor Mu had nothing but a frightened look. On the other hand, Su Shan, with blood flowing on his left thigh, limped, and turned around and shot while walking.

Luo Chen quickly understood the reason why the two of them were so flustered and embarrassed.

Immediately behind Su Shan and the others, several 'rat-shaped corpse brothers' were chasing and killing them, and that appearance was very familiar to him, it was the kind he had encountered in the small park before. Doubts rose in his heart, he didn't expect that even hospitals had such a thing.

The diesel generator rang all night last night, but except for the first few unlucky things, the back half of the ghost shadow did not attract it.

But at this time, he didn't think much about it, the pistol was raised, and the trigger was pulled.

Bang bang bang!!

His marksmanship was not very good, and more than a dozen bullets were missed, and he only hit two 'rat-shaped corpse brothers', but he successfully covered Su Shan and Professor Mu running over.

Bang! Bang bang bang –

There was a gunshot behind Luo Chen, which was obviously different from the sound of a pistol, it was Zhao Youyou's automatic rifle. Her marksmanship is obviously much better than Luo Chen's, and after 30 rounds of ammunition in one magazine, six or seven 'rat-shaped corpse brothers' have lost the ability to move.

"What's the situation?" Luo Chen looked at Su Shan and Professor Mu with a solemn face.

Su Shan was bitten off a piece of meat on his thigh, his face turned pale, and he replied in a suppressed voice: "I don't know what the situation is, we are cleaning up things, but this thing suddenly climbed in through the window, I didn't pay attention, and I was bitten." ”

Seeing that the danger had been eliminated, Professor Mu walked back and observed the 'rat-shaped corpse brothers' who were not dead from a distance of one or two meters.

It didn't take long for him to seem to notice something abnormal, and his face became ugly: "Something is wrong! We're in trouble! ”

Before he finished speaking, Zhao Youyou's voice suddenly sounded: "Luo Chen, stairs!" ”

Bang bang bang –

Seeing this, Luo Chen ran over in a few big strides, only to see more than a dozen 'rat-shaped corpse brothers' on the stairs fiercely climbing up with bullets.

Luo Chen didn't have much room to think about it, he directly changed the magazine, pulled the safety and pulled the trigger directly, and at close range, he condescendingly let him shoot several of them.

Professor Mu said loudly: "It's useless! There's more below! Damn, why are there so many rats mutating en masse and still staring at us! There's got to be something here that draws them in! ”

Luo Chen saw him lying by the window, knowing that Professor Mu must have seen something.

He asked aloud, "What's the situation?" ”

"Come to the window and look down!"

Luo Chen shouted: "Su Shan, your rifle has a fast rate of fire, come to the top!" ”

Su Shan was sweating on his forehead because of the severe pain in his thigh, but he couldn't care about the injury.

Seeing Su Shan coming over and using two rifles with Zhao Youyou to suppress a large number of 'rat-shaped corpse brothers' who wanted to rush up under the corridor, Luo Chen hurriedly ran to the window of the nearest room, looked down, and immediately gasped, and his scalp was numb.
