"It seems that these zombies are really invulnerable." Cheng Xu muttered.

Seeing this, Zhang Jiaxuan didn't say a word, and commanded a thunderbolt to come down, and the zombie fell.

Next, he released a lot of purple thunder one after another, and these scattered zombies were wiped out.

Chu Xiu released Xiao Lu, wanting to collect the crystal nucleus of this zombie, and then as soon as Xiao Lu came out, there was a burst of pain, obviously this red sunlight made it feel uncomfortable.

"Midori, what's wrong with you?" Chu Xiu hurriedly asked in his mind.

This little green is its treasure, and it has always been very powerful and has helped it a lot.

"This light makes me uncomfortable, and my whole body hurts." Such a voice came from Midori's consciousness.

"If you persist in persevering, you can see if absorbing the nutrients of these zombies can make you more comfortable." Chu Xiu hurriedly said.

"Hmm." Xiao Green responded, endured the pain, and went to smash and absorb the shells of these zombies, but even so, it kept crying out in pain, and even the branches and leaves looked a little wilted.

When Chu Xiu saw it like this, he was afraid of hurting it, so where did he dare to put it outside? I just hurriedly took it back.

After it received Xiao Lu, Zhang Jiaxuan and the two asked with concern: "What's wrong, what's wrong with Xiao Lu?" ”

"It couldn't stand the heat, so I got it into the system." Chu Xiu replied.

"That's really bad, if there is no little green, the speed at which we collect the zombie crystal nucleus will be much slower, and the safety will be greatly reduced." Zhang Jiaxuan said.

For a long time, the reason why they fought zombies so fast was mainly because Xiao Lu helped them collect crystal nuclei, otherwise, how much time would it take for them to take crystal nuclei one by one.

"When the time comes, I can only hand over this job to Big Orange and Big Spot." Chu Xiu said.

"I don't want it, I'm afraid of getting dirty." Big Tachibana hurriedly said.

Although Da Ban also had a hint of retreat in his eyes, he glanced at Zhang Jiaxuan and the two, and still nodded in agreement, "Then it's up to me then, but I need you to help me, I don't want to lick that dirty thing with my tongue." ”

"Okay." Zhang Jiaxuan nodded in agreement, and they continued to move forward.

It's already within the city limits, and next, they are more careful.

Just stepping into this urban area, the zombies that Chu Xiu saw before were somewhat gone, and the city was exceptionally quiet, with only the sound of various mutated insects crawling, as well as all kinds of strange insect chirping birds.

What used to be a noisy city has suddenly become a paradise for flora and fauna.

Zhang Jiaxuan didn't see the zombies, and deliberately threw down a string of firecrackers, trying to attract these zombies, but he didn't see the zombies coming up, but a pointed steel bar fell from a high place.

Zhang Jiaxuan's body flashed, but he dodged it, however, the big spot under him couldn't dodge, his body was inserted by this steel bar, and another piece of skin was brought down by this steel bar.

"Whew~" Da Ban exclaimed in pain, but this was not over, and next, one after another, the steel bars were swept down from those ruined high-rise buildings.

As a last resort, they had to turn on the Qingyan Shield.

It's also thanks to the fact that they have the Qingyan shield, otherwise, Big Spot and Big Orange will have to shed their skin if they don't die.

With their sheer size, there was no way to dodge the steel.

"Is this a human or a zombie?" As soon as he entered the city, he was attacked like this, and Zhang Jiaxuan was a little angry.

"Who the hell is it, just fly up and see if it's okay." Chu Xiu said.

After so long of cooperation, they also had a tacit understanding in their hearts, and almost at the same time, the two of them activated their flying wings and flew to the collapsed tall building.

They wanted to see who and who was doing such a cruel blow to them.

However, when they flew upstairs, there was nothing upstairs, and those sneak attackers behind them moved extremely fast, and disappeared in an instant.

"Not so fast, right?" You know, they flew up in an instant, how could these sneak attackers from behind be so fast?

Thinking like this, Zhang Jiaxuan had another steel bar behind him, and this steel bar used a huge force, even the Qingyan shield couldn't stop it, but in an instant, it broke Zhang Jiaxuan's shield, and at this moment, a huge snake flew out of Zhang Jiaxuan's neck and blocked the fatal blow.

"Blue Snake Ring, you saved my life again." At the moment when Zhang Jiaxuan was attacked, Cheng Xu had already used his ability in an instant, although he didn't see the sneak attacker behind the scenes, but he used the method of group control to directly control within a radius of 100 meters.

"Come before me, come before us." Although he didn't see anything he controlled, that didn't mean he couldn't control them.

This is the power of Cheng Xu, who has a third-level ability.

After a while, a lot of zombies came out from all corners, and they never knew that there were so many zombies in this seemingly empty and silent place.

"Whoever throws the steel bars at us, stand in front." At this time, Cheng Xu commanded again.

A lot of zombies stood up, and after these zombies stood up, Zhang Jiaxuan slashed them all to death with a few thunderbolts, and then, Da Ban slapped their heads with a claw, and after that, Zhang Jiaxuan went to take out the crystal nuclei in their brains.

"It's all golden crystal nuclei." Zhang Jiaxuan showed them the crystal nucleus, "Meow, I remember you said that the golden crystal nucleus is level three, right?" ”

"That's right," Chu Xiu nodded.

"It seems that the zombies here are all level three." Zhang Jiaxuan said, and chopped all the other zombies to death, as soon as they died, Cheng Xu, who controlled them, suddenly felt a lot less pressure.

He was also very tired to control so many zombies at once, and if he hadn't been promoted to the third level, he wouldn't have been able to hold back at all.

"Have all the zombies been killed?" At this time, Cheng Xu asked.

"Hmm." Zhang Jiaxuan nodded.

However, Cheng Xu felt that something was wrong, "No, I'm obviously still in control of something, and he's been consuming my abilities all the time." ”

"Huh?" When Zhang Jiaxuan heard this, he felt a little creepy.

"I can't hold on anymore." Cheng Xu's face became more and more pale, it seems that this person in the dark has good strength.

"Try to get him to show up." Chu Xiu reminded, "Maybe he has an invisibility ability. ”

"Please remove the invisibility." Cheng Xu only had time to say this, and his face turned pale.

And his words also succeeded in lifting the invisibility of the person in front of him.
