Everyone was already extremely tired, both physically and mentally, cold and hungry, even if they were not surrounded by zombies at this time, they would probably collapse to the ground if they ran like this for another ten minutes.

The rain was falling relentlessly, sprinkling cold droplets of water on the few people who were surrounded, as if they were doing some kind of experiment, wondering how long they could last, adrenaline had a miraculous effect, but it was timely, it had been so long, they could no longer rely on adrenaline to eliminate the cold and pain.

There is no hope, everyone is already a little discouraged, and the solutions they can come up with are all related to sacrifice.

"Wait!" Bai Cheng grabbed Shen Shizhong, who was about to rush out.

Shen Shizhong planned to knock down some zombies and create a gap, the zombies' balance ability was not very good, and they were easily knocked down, and the rest of the people rushed out of the gap and should be able to run back to the villa.

"Brother Cheng, it's all this time......" He turned to look at Bai Cheng anxiously, after a while, the encirclement was smaller, there was no room for him to sprint, he was worried that he would not be able to push down a sufficient number of zombies.

Before he finished speaking, Shen Shizhong saw Bai Cheng raising his head, staring at a certain place, his expression was grim, and he even forgot to let go of his clothes and followed his gaze.

The two of them suddenly fell silent, causing others to look at them as well, seeing the sluggish Bai Cheng and Shen Shizhong, who were also stunned, and they also followed their gaze to look over there, and they were also stunned.

I saw a dark figure standing on the roof of a villa, carrying two sledgehammer-like things, looking down at this side, and the raindrops made some mist around him, making him look a little tall.

"Sun An?" The rain kept hitting his eyes, Bai Cheng couldn't see it really, and tried to scream.

The man on the roof immediately stepped back and disappeared from their sight as if it had not existed in the first place, but everyone had seen the man, and it was not a hallucination.

A few seconds later, the figure reappeared, leaping out of the rooftop, raising its twin hammers and falling into the still approaching zombie horde.

A horizontal bolt of lightning appeared in the clouds, causing the thick clouds to light up like fluorescent lamps, illuminating the man flying in the air with a sledgehammer.

It's Sun An, Bai Cheng is a little excited, Sun An has a smile on his face, he looks a little evil, but he is still laughing, which means that Bai Yue should be fine, so no matter how weird the smile is, Bai Cheng will not care.

"Boom!"

The mailbox hit the heads of the two zombies solidly, smashing them to the ground, Sun An, who jumped into the zombie pile, waved the mailbox, and quickly knocked the surrounding zombies to the ground, beckoning to Bai Cheng and them.

Bai Cheng and the others immediately rushed out of the encirclement from that gap, and followed Sun An to and fro on the road, all the zombies were gathered together, and there was no need to block the road in front of them in advance, even if there were, they were not Sun An's opponents.

Running out, Sun An slowed down and joined Bai Cheng and the others.

"Why do you want to run? Why don't you take down all the zombies, you can knock them down with ease. Without waiting for Bai Cheng to speak, Shen Congyi frowned and asked Sun An.

"What are you doing?" Shen Shizhong snorted, "Mr. Sun saved you, what kind of attitude do you have?"

Although he said so, he also glanced at Sun An suspiciously, Sun An easily defeated those zombies, and the defeated zombies will never move again, even if he doesn't kill all the zombies, it's always good to knock down more.

Shen Congyi was stunned for a moment, this is the second time he has been reprimanded by his father in a short period of time, the previous time the situation was urgent, and he admitted it when he was yelled, but now there is nothing, and his father is obviously helping outsiders, he didn't dare to disobey Shen Shizhong, just gritted his teeth and glanced at Sun An's back angrily.

"She's okay, right?" Bai Cheng glanced back at the Shen family's father and son, and asked Sun An as he ran, although he was already very tired, Sun An's appearance made them see hope, and there seemed to be some strength in his body.

"It's all right, they stayed in the car, in the alley next to the office building to the west. Sun An also turned back while running, but he was looking at those zombies, and kept adjusting his running speed, he suddenly became the backbone of this team, and the others also followed him and ran fast and slow.

"That's good, that's good. Bai Cheng was completely relieved at this time, and glanced back at Shen Congyi again, seeing this young junior following behind with a straight face, he felt that Shen Shizhong had said a little too much, and he couldn't accuse others of how to educate children, so he had to ask Sun An: "Why didn't you knock down a few more zombies just now?" ”

This question gave Shen Congyi a step down.

"It's not time yet, I need to observe them, in fact, I just arrived, but I didn't show up, I kept watching. Sun An said as he ran.

Shen Congyi frowned, and looked up at him again, just now he didn't come out to save people, and he didn't show up until he got the most dangerous moment, this is playing handsome, right? If it was a little later, Shen Shizhong would rush out and sacrifice himself.

"What are you observing?" Bai Cheng asked curiously.

"Observing their actions, the real threat is not these zombies, it is the person who made zombies with blood, that guy is hiding in the shadows, if you don't find it, there will be more zombies in the future, I want to find that person through the agility and running speed of zombies. Sun An was still looking back and watching.

"Has the speed changed?How do you find people by speed?" Bai Cheng asked again.

"These zombies chasing you are much slower than those chasing me before, both in terms of speed and flexibility, I guess because they are too far away from their 'masters', their abilities are limited in range, long-range control capabilities, the farther away they are, the worse the effect, it is easy to understand them as eavesdroppers, the farther away from the eavesdroppers, the lower the frequency of the tick, and the closer they are, the higher the frequency of the sound. Sun An said in a deep voice.

"But it's hard to observe. Bai Cheng glanced back, and the zombie ran up and stumbled, unable to see how fast it was.

"Indeed, running on the ground can only estimate the approximate distance, judging the change by your own speed, it is not reliable, so you run, don't run too fast, don't get out of their field of vision, they will not be scattered, take them everywhere to practice, it is best to always keep a certain distance from them, I observe from a high place, it is much more convenient to have a reference, I will come down to save people when you are in danger. Sun An glanced at Bai Cheng and saw that this middle-aged man was so tired that he was about to droop his tongue, but there was nothing he could do.

"Okay, you go, let's keep running. Bai Cheng agreed.
