As the corpses retreated, the pressure around Chu Fei relaxed, and without pressure, a feeling of exhaustion instantly came from his body, almost making Chu Fei faint.

Chu Fei's body shook a few times, slammed the spear in his hand to the ground, and forcibly stabilized his body, he knew in his heart that a greater crisis was coming.

The advanced zombie ran in front of Chu Fei with an excited face, its huge body was like a tank, and the entire restaurant shook slightly.

Chu Fei stabilized his mind and stared at the mutant zombies with all his attention, and the collision of the mutated zombies brought a momentum, which made Chu Fei a little afraid to touch it.

But the scope of the restaurant was only so large, Chu Fei couldn't dodge it at all, so he had to pick up the recliner and condense all the energy in his body on it.

"Bang!"

With a loud bang, the huge body of the advanced zombie instantly collided, and the energy on the recliner flickered, but it was unable to resist the attack of the advanced zombie at all, and the entire chair was smashed to pieces.

And after smashing the chair, the momentum of the advanced zombie continued unabated, and it still slammed into Chu Fei's body.

"Wow!"

Chu Fei spat out a mouthful of blood, and the whole person flew backwards in the air as if he had been hit by a heavy truck.

What kind of strength is this, Chu Fei felt that his body was about to fall apart, and all the internal organs in his body were rolling, and he couldn't stand up after being hit for a while.

With a successful blow, the mutant zombie laughed fiercely, stretched out his big hand and grabbed Chu Fei, and next, it was about to enjoy the prey in its hands!

Without any obstruction, Chu Fei was grabbed by the big hands of the advanced zombies, and the powerful force seemed to crush him, making him feel that the bones inside his body were about to shatter.

The mutant zombie grabbed Chu Fei's body, opened its hideous mouth, revealing a mouthful of jagged fangs, and opened its mouth to bite Chu Fei's body.

"Sting~ Bang!"

The lights of the restaurant suddenly turned on, and the zombies within the storefront were instantly hit by an unknown force, and even the terrifying advanced zombies suffered heavy damage.

The advanced zombie was hit hard, and the powerful force forced it to let go of the right hand that grabbed Chu Fei, and the huge body was knocked out along with the scattered ordinary zombies.

After cleaning up the zombies in the storefront, a transparent defensive light curtain immediately appeared on the outside of the restaurant, covering an area more than twice as large as before!

The duck flew away, and the mutant zombie was naturally extremely unwilling, roaring and hitting the defensive light curtain outside, but its attack strength couldn't even make even a ripple appear in the light curtain.

System! It's time for the system upgrade!

The desperate situation made Chu Fei ecstatic in his heart, only those who have really faced death can feel the beauty of life! Chu Fei was naturally excited, but he couldn't help himself.

But because the injuries on his body were too serious, Chu Fei couldn't move his body at all, and could only lie on the ground like a broken doll, his eyes staring straight at the ceiling.

"System, I was bitten by a zombie, will I have to rely on your fruit to sustain my life in the future?" Chu Fei's eyes were a little stunned, and he muttered to the system in his heart.

"No, there is systematic protection, and no virus can invade the host of the system's choice."

Hearing such an answer, Chu Fei was naturally even more surprised, he didn't expect that the system would have this kind of effect!

As if thinking of something, Chu Fei's face was a little strange, and he silently asked the system in his heart: "You actually have an anti-virus function, don't say that you are researched by Jinshan Poison Tyrant." ”

"What is Geumsan Poison Bully? You don't have permission to know my origin right now, please ......"

"Do you want me to figure it out on my own?" Chu Fei rolled his eyes and interrupted the system's words, he was a little tired of hearing this sentence.

However, if the system hadn't been upgraded in time, he would have been the food in the zombie's mouth by now, and the system would still be his savior.

For some reason, since Chu Fei knew that the system had emotions, he had become more and more concerned about the system as a real life.

For a long time, without hearing the system's reply, the corners of Chu Fei's mouth rose slightly, raised his chin triumphantly, and turned his head to look outside.

It seems that the previous smell has not dissipated, or maybe the advanced zombies have low intelligence, and the corpses outside the door are still persevering in the attacker's defensive cover, and the huge number makes people's scalps a little numb.

"Hiss~"

It seemed that the movement of turning his head had touched the wound, Chu Fei gasped, his brows furrowed slightly, he really didn't expect his injury to be so serious.

But after all, he survived, which is really not an easy thing, if he were to be replaced by another ability, I am afraid that at this time, he would have already been converted into the energy in the corpse.

Chu Fei blinked slightly, and muttered in his mouth: "Alive...... That's nice! ”

The crimson morning glow soaked the eastern sky, and the vast land was still immersed in the deep night, and the red clouds in the sky were criss-crossed, spanning the sky, and in the black-covered voids, they bloomed with wanton agitation.

After such a long delay, it is almost early in the morning, and it will not be long before there will be customers coming, and it is not good to let them see the embarrassed appearance of the restaurant when the time comes.

Chu Fei thought in his heart, struggled to get up from the ground, limped to the dining chair next to him and sat down.

In the first battle, a lot of zombies were killed, and the corpses of these zombies were still lying on the ground at this time, and it was estimated that they could dig out a lot of crystal nuclei.

Thinking of this, Chu Fei was slightly excited in his heart, and bent down with great effort, looking for the crystal nucleus in the pile of corpses.

Enduring the pain coming from his body, Chu Fei rummaged through the skulls of zombies, for some reason, the yield rate of this batch of zombie crystal nuclei was much higher than before.

The last time I killed nearly thirty zombies in the open space outside the restaurant, I only found eight crystal nuclei, and this time every three zombies can produce one crystal nucleus on average.

The explosion rate is much better than before, and the strength of this batch of zombies has also improved a lot compared to before.

It seems that zombies are also evolving, which Chu Fei had expected when he saw the crystal nucleus level listed by the system, but he didn't expect that the speed of zombie evolution would be so fast.

This situation also gave him a sense of crisis in his heart, and if he didn't hurry up to improve his strength, he didn't dare to guarantee that the restaurant would continue to open.

After more than half an hour of searching, Chu Fei found nearly thirty crystal nuclei, if calculated according to the explosion rate of crystal nuclei, the number of zombies killed this time was close to a hundred!

This is a very large number, you must know that only Chu Fei made the shot, and the time is only about twenty minutes, it is already unbelievable to have such a harvest!
