Chapter 579

The sentinel in the steelwalker camp found several figures not far away. He immediately took out his whistle and blew it hard.

The sound of the whistle is very light, but it is very penetrating. After many experiments, the sound of the whistle will not be noticed by the undead.

As the survivors of the steelwalker camp extended the safe area to a few streets of the aristocratic quarter and occupied an access to the trade zone, there were defensive gaps in many places.

However, it was difficult for Guo Yunfeng. He directly classified the steel Walker infantry battalion as an absolute safety zone. Six hundred fully armed soldiers were divided into three shifts and patrolled the camp 24 hours a day. There was a sentinel observation post every 15 meters.

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

Every day after the sun rises, a special cleaning team goes out to kill the undead who enter the secondary safety zone at night before opening it to others.

These scouts and search teams set out from here to carry out their missions outside. Guo Yunfeng also organized many people to dismantle the houses here to expand the cultivated land area as much as possible.

Throughout the day, armed patrols patrol the secondary security zone. Sentinels are set up at each intersection and commanding point. These whistles are specially assigned to sentinels to call for support.

Guo Yunfeng, a former warden, is absolutely professional in arranging patrols and sentry posts. No matter where someone blows his whistle, a 10 member patrol team will arrive in two minutes.

"I'm Scott!" Scott, with his pockets full, looked around to make sure there were no undead in the street, and he ventured to shout, "Nur and I have found a survivor!"

"Be honest and stay down here!" The sentry stood still on the roof of a house. Seven or eight corpses formed a trench in front of him: "I will let you in until the patrol arrives."

From Xu Yichen's point of view, only the tip of a long bow can be seen from time to time behind the trench.

"He's a little nervous. The patrol will come soon. We just need to be careful." Scott turned and walked back to the Hunter: "normal scouts shouldn't come back so early. We're illegal, but there was an accident just now, and I think they'll understand."

Xu Yichen nodded. In the face of biochemical crisis, he can organize an effective system, which represents ability and execution.

After a while, the sound of footsteps and the crash of armor came from behind the barricade.

The sentry and the patrol team simply communicated, stood up from the back of the trench and waved to Xu Yichen.

"We can get there!" Scott tightened his clothes and tried to make his bulging pockets and parcels look even: "people who come back from the outside will have to stay in the quarantine area for a few hours before they can enter the camp until they are sure they are not infected."

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

The demon hunter noticed that the whole barricade was built with the remains of a carriage as the main body. Dozens of corpses were filled on both sides of the carriage, and were fixed together with spears and wire. The demolished gate was spread on the outer side of the barricade.

It can't be seen from far away, but when we get closer, we will find that the corpses are basically undead with limbs cut off. Many people are still staring at the coming and going survivors with their eyes open, and they can only make a very weak roar.

But their teeth have been knocked out, and many of them have been directly pulled from their lower jaw, leaving only a black tongue to swing around.

A rope was thrown from the barricade, and a bearded man in steel Walker's infantry armor stood on the barricade: "come up one by one. I can climb up only when I say next!"

Xu Yichen pushes Nur to let the youngest and most timid survivor go first. With his perception, he has faintly heard the howl of the undead.

When Nur had just reached the top of the barricade, seven or eight undead followed the scent of the demon hunters and turned from one side of the street.

"Attention! The immortal, eight! " The sentry got up from behind the trench, ran forward, hopped on the roofs of houses, and soon reached the end of the street. He needed to determine how many undead were following.

"More than 30!" Ignoring the danger of being found, the sentry yelled in the distance.

Mustache's face was a little ugly, and he called out to Scott below, "you two, climb quickly. We have to prepare for the defense before the undead arrive!"

Scott hesitated for a moment, first looked at the hunter, saw that the other side did not want to move, then began to climb with a angry smile.

Unfortunately, the small businessman who refused to let go of the opportunity had too many metal items in his pocket and backpack. Along the way, he refused to let go of the silver plated candlestick.So he was weak to climb. The nearly three meter barricade made Scott blush. If it wasn't for the mustache who couldn't look down, he reached out and pulled him. I'm afraid the middle-aged guy was still hanging in the air.

"Say, Cyrus, hurry up!" Mustache looked at the undead who had already turned in the distance. He lay down on the barricade and stretched his arm as straight as possible: "you can't be a embroidered pillow like that idiot!"

The Sentinels on the roof ran back and arched at the same time. However, most of these soldiers only waved their heads and were powerless to bow and arrow.

The arrow shot through the leg of an immortal. If it was not for the other leg, sometimes it would touch the arrow, which made its pace not so coherent. I'm afraid the immortal didn't find himself hit.

Xu Yichen didn't refuse the other party's kindness. He stepped on the barricade, pulled the beard's hand, and then turned over and jumped on the barricade.

On this side of the barricade was a slope of corpses, but the heads of the corpses had been cut off, and the defenders standing on them did not have to worry about being accidentally bitten by the undead.

"Hum!"

Xu Yichen turned and opened his bow and shot an arrow. The immortal running in the front didn't even shake for a moment, so he was shot through his head and fell to the ground straight and disappeared under the feet of other immortals.

"You need a whole body?" In the process of speaking, the demon hunter has shot a second arrow.
