In the originally deserted suburbs, at this time it was in full swing, and more than 10,000 construction workers, with the cooperation of each other, built the fence at a rather terrifying speed.

Since these recruits were all evolutionaries, they moved quickly and quickly, and the wall made of bricks continued to rise at a speed that could be seen by the R eye.

Trucks shuttled back and forth from the construction site to drop construction materials into the construction site, and then quickly returned to the base to haul more materials over.

It can be said that the construction of this section of the wall alone requires a lot of materials, as well as the various resources required for future reinforcement and base construction are astronomical.

Fortunately, Sun Xue had the foresight to release the mission at the beginning, so that the mercenary team would mainly collect these materials, so the materials for building this outpost were still sufficient.

While Sun Xue and the people in the logistics department were constantly deploying manpower and materials to build the wall, Peng De was also busy deploying manpower.

Although they have eliminated all the zombies in this vicinity during the day, as night falls, the range of zombie activities has increased, and some zombies have gradually noticed this side.

These zombies are roaring loudly with excitement, calling their companions around them.

The soldiers of the Division of Hope, under the transfer of the command staff, divided into squads and entered the surrounding houses.

Although it was a battle with the zombies at night, they were not worried at all.

First of all, the scale of this corpse tide is not a threat to them, and more importantly, without the command of the zombie king, these zombies are just a plate of scattered sand.

The surrounding houses are well used, they are fortresses one by one, as long as the doors and windows are guarded, no matter how many ordinary zombies come, they are just looking for death.

The only thing that worries them a little is probably the mutant zombies, but there is a sniper at every distance of this defense line in order to deal with these mutant zombies.

Roar, roar, roar!

The roar of the zombies got closer and closer, and finally at some point, the gunshots suddenly rang out, which meant that tonight's battle had officially begun.

Sudden Sudden Rush!

The fierce gunfire made the temporary workers who were building the wall a little nervous, especially those mercenaries, who subconsciously clenched the weapons on their waists.

To be honest, in such a situation, it is impossible for them not to be nervous, as long as the army can't defend it, then with the madness of these zombies at night, they will definitely die for life.

However, what they feared did not happen, the army set up a defensive line between the two streets close to here, and now these zombies can't even break through the first line of defense, let alone threaten their lives.

And at this time, the main battle tanks also appeared in their field of vision, and these tanks did not stop until they were ten meters away, and then lined up to form a third temporary line of defense.

Looking at the last line of steel defense formed by the main battle tanks, these people in the field finally felt completely relieved, and at the same time accelerated the construction speed in their hands.

In this way, amid the sound of artillery fire, a five-meter-high wall stretching for a kilometer was built in half an hour

The men then quickly got into trucks and headed to the next area, and the army's line shifted with it.

As for the newly built wall, no one paid any attention to it, because the zombies couldn't have been interested in a wall.

Of course, even if it is really attacked, the collapsed part can be quickly repaired afterwards.

It didn't take long for the construction workers to move on to the next location and continue to build.

As for the army, although it is a little troublesome to transfer, it is not a big problem to have the main battle tank as cover. Soon, they all moved accordingly, forming a line of defense again.

Of course, the problem is not without problems, the mutated zombies at night are indeed terrifying, especially the night demons are even more difficult to prevent.

So in this short half an hour, more than 20 soldiers died, you must know that they killed more than 30 people after a whole day of cleaning up zombies.

It can be said that fighting against the corpse tide at night is definitely not worth the loss, but seeing that these zombies are about to enter the third order on a large scale, Ye Feng can't afford that time, so he can only rush to work overnight and build the outpost as soon as possible.

And all he can do now is to send Li Feng, Huang Haotian and other supernatural beings out to kill as many mutant zombies as possible.

As for Ye Feng himself, in fact, in such a situation, he has nothing to do, even if he has strong combat effectiveness, but in the face of a one-kilometer defense line, even if he kills zombies, it will be useless. And in terms of command, there are Peng De and others, so he is even more unnecessary.

So Ye Feng's choice is...... Practice.

That's right, under such a big battle, Ye Feng can also continue to cultivate, this mentality is definitely not comparable to normal people. If it were a different person, let alone cultivating in such an environment, it would be difficult to be calm.

Even Peng De, after hearing this, was speechless for a while, and he felt a little drunk for Ye Feng's big-hearted behavior.

It's just that in such a situation, Ye Feng really can't help much, plus the identity of the marshal, so in this kind of big war, no one said anything about making such a ridiculous act of cultivation.

The battle lasted all night.

This night, Ye Feng had been cultivating in the command car from beginning to end, and it seemed that he had been affected by the atmosphere of war, and the effect of his cultivation was particularly obvious.

And they successfully achieved the expected goal, and at six o'clock in the morning, a wall of nearly 20 kilometers was finally built.

Although this wall is still very weak, and even tens of thousands of corpses can't resist it, the establishment of this line of defense is like building a wall in everyone's hearts, giving them a sense of security.

As the sun rose, the frenzied tide of corpses receded, and all that remained was to reinforce the walls.

These will be arranged by Sun Xue's side, and the army side is also very tired after nearly a day and a night of fighting, and under Ye Feng's order, they retreated to the base of Xin'an City to rest.

As for the newly built outpost, with this wall, it would be easy to deal with the scattered zombies.

Because as long as there are not many people, there will not be too many zombies around, and those mercenary groups who go out to collect supplies can solve them.

When Ye Feng and the others returned triumphantly, the survivors in the base finally let out an earth-shattering cheer.
