The sentries in the Steel Walker Camp discovered several figures not far away, and immediately took out the whistle at his waist and blew it hard.

The whistle sound is very light, but it has strong penetration. After many tests, the sound of this whistle will not be noticed by the undead.

Because the survivors of the Steel Walker Camp expanded the safe zone to several streets in the noble area and occupied a passage to the trade zone, defense gaps appeared in many places.

However, this did not endure Guo Yunfeng. He directly classified the Steel Walker Infantry Battalion into an absolute safe zone. Six hundred fully armed soldiers were divided into three shifts and patrolled the camp for 24 hours a day. There was a sentry observation post every fifteen meters.

The expanded territory is a secondary security zone, or buffer zone, and is temporarily blocked with corpses and other simple materials. Every day, the sun sets, and everyone must return to the absolute security zone to move.

Every day after the sun rises, a special cleaning team will be launched, killing the undead who enters the second-level safety zone at night before opening it to others.

The scouts and plundering teams set out from here to go to perform missions outside. Guo Yunfeng also organized many people to demolish the houses here and expand the arable land area as much as possible.

During the day, armed patrols were patrolling everywhere in the second-level security zone, and sentries were arranged to hold guards at each intersection and commanding heights. This kind of whistle was specially distributed to sentries for call support.

Guo Yunfeng, who used to be the warden, was absolutely professional in arranging patrols and posts, and ruled out the intentional laziness of the personnel. No matter where someone blew the whistle, a patrol team of ten people would arrive within two minutes.

"I'm Scott!" Scott, who was full of pockets, observed left and right, and after confirming that there were no undead people on the street, he shouted boldly: "Nur and I found a survivor!"

"Stay honestly below!" The sentry was unmoved and stood on the roof of a house. Seven or eight bodies formed a trench in front of him: "I can only let you in when the patrol arrives!"

From Xu Yichen's perspective, you can only see the tip of a longbow appearing behind the trench from time to time.

"He was a little nervous, and the patrol would come soon. We just need to be careful." Scott turned around and walked back to the Demon Hunter: "Normal scouts shouldn't come back so early. We were illegal, but an accident just happened, and I think they would understand."

Xu Yichen nodded. When facing the Resident Evil, he was able to organize an effective system, which represents ability and execution.

After a while, footsteps and armor collisions came from behind the barricade.

The sentry and the patrol team communicated briefly, stood up from behind the trench, and waved at Xu Yichen and the other two.

"We can go over!" Scott tightened his clothes, trying to make his bulging pockets and packages look flatter: "People who go back from outside should stay in the quarantine area for a few hours before entering the camp after they are sure they are not infected."

Xu Yichen nodded and followed Scott and Noor to the barricade.

The demon hunter noticed that the entire barricade was built with the wreckage of a carriage as the main body. Dozens of corpses were filled on both sides of the carriage, fixed together with spears and wires. The entire disassembled door was laid flat on the side of the barricade facing the outside.

It is still impossible to see when you are far away, but when you are close, you will find that the corpses are basically undead whose limbs have been cut off and incomplete. Many people are still keeping their eyes open and staring at the survivors coming and going, and can only make extremely weak roars.

But their teeth were knocked off, and many of them were pulled and hung up their jaws, leaving only a black tongue to sway.

A rope was thrown off the barricade, and a bearded man in the armor of Steel Walker Infantry stood on the barricade: "Come up one by one, and I will only be able to climb up when the next one!"

Xu Yichen pushed Nuer and asked the youngest and most timid survivor to take the lead. With his perception, the howling of the undead could be vaguely heard.

When Noor had just climbed to the top of the barricade, seven or eight undead people turned over from one side of the street, following the scent of the demon hunters and they left.

"Note! Eight undead!" The sentry stood up from behind the trench and ran forward, jumping flexibly on the roofs of houses, and soon arrived at the end of the street. He needed to determine how many undead people were following him.

"More than thirty!" The sentry shouted in the distance without caring about the danger of being discovered.

The bearded man's face suddenly looked a little ugly, and he shouted at Scott below: "You two, hurry up and climb, we must be prepared to defend before the undead arrives!"

Scott hesitated for a moment, took a look at the demon hunter and saw that the other party had no intention of moving, and then began to crawl with a disappointed smile.

Unfortunately, this little businessman who refused to let go of his chance had too many metal items in his pockets and backpack. Along the way, he refused to let go of silver-plated candlesticks.

So at this time, he was a little weak. The barricade of nearly three meters made Scott blush. If the bearded man couldn't stand it and reached out and pulled him, I'm afraid this middle-aged guy would still be hanging in the air.

"Hey, Seris, hurry up!" The bearded man looked at the undead who had already turned around in the distance, lay on the barricade, straightening his arms as straight as possible: "You won't be an embroidered pillow like that idiot!"

The sentries on the roof ran back and shot arrows, but most of these soldiers had only waved their heads and were really powerless towards things like bows and arrows.

The arrow shot through an undead's calf. If it weren't for the other leg, it would sometimes touch the arrow, making its pace less coherent. I'm afraid that the undead would not have found himself hit.

Xu Yichen did not refuse Fang's kindness, so he kicked the barricade, grabbed the bearded man's hand, and then turned over and jumped onto the barricade.

On this side of the barricade is a slope made of corpses, but the corpses have been cut off their heads. The defenders standing on them do not have to worry about being accidentally bitten by the undead.

"Buzz!"

Xu Yichen turned around and shot an arrow. The undead who ran in the front was shot through his head without even shaking it. He fell straight to the ground and disappeared at the feet of other undead people.

"You really need a complete corpse?" The demon hunter had already shot a second arrow while speaking.
