Time passed little by little, and the whole brain domain evolved zombies did not have the slightest intention of coming out, and the attack of ordinary zombies on dormitory buildings and office buildings was not strong, mainly besieged, and it was enough to prevent Wei Yun and Zhou Zhen from escaping.

After Xiao Ran rested for three hours, both mentally and physically recovered.

And Wu Chao finally came back with someone.

Wu Chao knew that Wei Yun and Zhou Zhen were trapped inside, and after going back, he hurriedly went to find Luo Ji, mobilized heavy weapons, reorganized the manpower, and came back to rescue as quickly as possible.

It's just that heavy weapons are not easy to prepare, and the road from the thermal power plant to the town hall is not very good, so it took more than three hours.

If Xiao Ran hadn't killed those four evolved zombies, Wei Yun and Zhou Zhen might not have been able to hold out for so long.

Xiao Ran came down from the upper floor and found that Wu Chao not only brought two artillery pieces, but also two additional machine guns, and also brought a large number of shells with a truck.

Before, Chen An only attacked with a machine cannon for ten seconds, and easily blasted hundreds of zombies at the gate into pieces, how could this not make Wu Chao's eyes red?

In order to save Wei Yun and Zhou Zhen back, Luo Ji also made a lot of money.

When he saw Xiao Ran, Wu Chao hurriedly asked, "Brother Xiao Ran, how are Wei Yun and Zhou Zhen doing?" ”

Not only Wu Chao, but the people behind him were also anxious, and even Chen An had a deep worry on his face.

Xiao Ran smiled: "They are fine, there were originally four evolutionary zombies in it, but they didn't have long eyes, so they had to come to me for trouble, and they were killed by me." ”

Four evolved zombies, all killed by Xiao Ran?

Wu Chao showed a look of surprise, he knew that Xiao Ran was very powerful, but he never thought that Xiao Ran would be so strong, fighting against four evolved zombies alone, and he won!

If he knew that Xiao Ran not only had to fight against four evolved zombies, but also thousands of ordinary zombies participating in the siege, he would probably be so frightened that he couldn't speak.

"Okay, hurry up and arrange it, it's important to save people."

Xiao Ran is the commander-in-chief of this battle, and since the heavy weapons have arrived, of course the rescue operation must start as soon as possible.

The two cannons were placed separately, so that Wu Chao and Chen An each led people to guard the artillery to prevent the zombies from rushing over and destroying the artillery.

Then Xiao Ran arranged for the other two capable people to divide into two teams, each leading ten people and getting into three pickup trucks.

One pickup truck has a machine gun on it, and the other two vehicles have light machine guns, and the two convoys have six fire points, which cross each other to cover each other, which can cause maximum damage to the zombies while moving.

With Xiao Ran's order, the two artillery pieces fired at the same time, and the zombies gathered at the gate of the thermal power plant were instantly blown away.

The artillery is so powerful that it can easily destroy a building, and now it is useless to kill ordinary zombies!

Moreover, in order to prevent Xiao Ran from leading people to break through, the whole brain domain evolution zombies deliberately let ordinary zombies take a dense position, almost one by one, and a cannonball can kill at least dozens of zombies.

With just two shells, the zombies at the gate were disorganized.

But Xiao Ran didn't mean to stop there, since he knew that there were tens of thousands of zombies in the thermal power plant, and there was a powerful full-brain domain evolution zombie, why did Xiao Ran want to fight them hand-to-hand?

Is it bad to wash the floor with direct artillery?

The artillery continued to roar, and the sound spread for more than ten miles, and the survivors nearby heard the movement and came out to check.

Some of them were bold, and when they got closer, they found that it was artillery, and they were immediately frightened.

The use of artillery to attack the thermal power plant also demonstrated the strength of the official Los Angeles survivor base, and after the battle, more and more people spontaneously went to the official Los Angeles survivor base, which greatly increased the strength of the official Los Angeles survivor base.

Of course, these are all later words, and they are not what Xiao Ran cares about.

More than a dozen shells went down in a row, and although the zombies at the gate were not completely wiped out, they had also lost their formation, and the zombies who were not harmed were also stunned by the roar of the shells, and they were stunned in place and at a loss.

"Stop!"

Xiao Ran signaled Wu Chao and Chen An and started moving forward with the two convoys.

The light machine gun began to fire from afar, cleaning up the zombies who were stunned by the artillery and had no time to escape.

The two light machine guns did not fire together, but staggered the time to ensure that the two light machine guns would not be without bullets at the same time, and at least one fire point existed.

The two convoys crossed cover, and these zombies at the gate were not vulnerable at all, and they were easily broken through by the convoy.

After the breakthrough, Xiao Ran did not rush to rescue Wei Yun or Zhou Zhen, but guarded the gate and asked Wu Chao and Chen An to come over with artillery.

The gate is everyone's retreat, and there must be no mistakes.

Taking advantage of the time when Wu Chao and Chen An transported the artillery, Xiao Ran led the two convoys to continue to clean up the zombies near the gate.

At this time, the whole brain domain evolution zombie came out again.

It originally thought that if it didn't provoke Xiao Ran, the matter would be over, but it didn't expect Wu Chao to come back with artillery.

The power of the artillery was so strong that even the whole brain domain evolved zombies were frightened and hurriedly came out to check.

The evolutionary zombies in the air told Xiao Ran about the situation, and Xiao Ran hurriedly used the walkie-talkie to contact Wu Chao, asking him to adjust the angle of the artillery as quickly as possible and launch an artillery attack on the whole brain domain evolutionary zombies.

Originally, Xiao Ran didn't know where the whole brain domain evolution zombie was hiding, so he could only advance little by little, but he didn't expect it to take the initiative to appear.

Taking advantage of the fact that the whole brain domain evolved zombies did not know enough about artillery, they had to kill it fiercely!

It would be best if you could take away the whole brain domain evolution zombie with one shot.

Wu Chao received Xiao Ran's order, and hurriedly asked people to adjust the angle of the artillery, and launched it as fast as possible.

The shell streaked a parabola through the air and landed precisely in the zone of movement.

It's a pity that Wu Chao is not a professional gunner after all, and the evolved zombies can't accurately express the location of the whole brain domain evolution zombies, although this cannon fell into the sports area, but it is still fifty meters away from the whole brain domain evolution zombies.

Rumble!

The shells exploded, the terrifying heat wave dispersed, and a large number of shrapnel flew out, almost completely tearing the zombies within a radius of more than ten meters to pieces!

Those zombies who were lucky not to be torn apart also flew up under the huge impact.

With just one attack, dozens of zombies are killed!

When the whole brain domain evolved zombie saw this scene, he subconsciously let out a scream, and no longer bothered to observe the situation, and hurriedly retreated.

If it doesn't leave, it might be blown up!

Rumble!

The second cannonball also fell, and it was less than thirty meters away from the whole brain domain evolved zombie!

Then one after another cannonballs fell, and the whole brain domain evolution zombies ran away, but those ordinary zombies were killed by at least hundreds.
