The bear has a bitter smile on his face. He poked a hornet's nest today. I never dreamed that there were thousands of mutated zombies hidden in the municipal exhibition hall. Now the zombies are chasing like zombies. This is called heaven has no way to enter the earth.

"Well, don't think about it. You think a bald head is a lighthouse! The mutant zombie hidden in the municipal exhibition hall is a shit pit. If you don't touch it, it will explode, which can only be your bad luck!"

When Xiao Xia said this, the bear's mentality was better and no longer tangled: "how can there be so many mutant zombies in the municipal exhibition hall? It seems that we fell into the trap of zombies. Now I'm a little worried about them?"

"Take care of yourself first!"

A platoon brought by Xiao Xia and a platoon of bears, but now there are less than 30 people hiding behind a statue to block the attack of mutant zombies.

The bear had lost its combat effectiveness. He looked up at the statue and said to himself, "what do I think of this statue as the goddess of liberty? It seems to be smiling at me!"

Xiao Xia threw out the last grenade and spat out a mouthful of blood foam. "I think you are a flower maniac!... eh! You really look like my woman. Your chest, waist and face are really a bit like me!"

They looked at each other and smiled, quietly waiting for the final judgment of fate, "are you afraid of death?"

"Fear! Who is not afraid of death? It's not easy to survive. Why die..."

The bear closed his eyes, and Xiao Xia's voice in his ear became weaker and weaker. It seemed that he heard something. He suddenly opened his distracted eyes, "listen,... It's gunfire".

"Of course, it's the gunshot." Xiao Xia threw the gun underground after the last bullet. He no longer reported any illusions. He bared his teeth and said happily: "now there's really no ammunition, and the gunshot...".

"It's really gunfire. I heard the roar of the engine. Lu team came to save us!"

The huge roar came from a distance, and the dense gunfire pounded everyone's heart like a rainstorm, "dada......" Xiao Xia seemed to hear the horn of the charge, leaned hard on the statue, supporting her weak body and looked away.

As the dense gunfire got closer and closer, the surrounding mutant creatures were in a short panic. Some mutant zombies ready to rush up suddenly turned around and rushed in the direction of the gunfire.

Xiao Xia saw the mutant zombies flying around and thrown up high, and the broken limbs and meat splashed in the air, like waves smashed one after another. It seemed that a beast rushed into the zombie pile with unstoppable momentum, the dense zombie encirclement circle was torn and crushed, and a painted black machine monster appeared in their vision.

"What is this?"

Xiao Xia has never seen such a strange machine monster, a huge V-shaped shovel head. There are four Gauss machine guns on the top of the carriage, and two high machine guns on both sides. Dense bullet rain is shot from eight Gauss machine guns, forming a tight fan. From time to time, fire dragons are sprayed from around the car body, Like a sharp knife inserted into butter, it tore apart the surrounding ring of the zombie.

The windy machine monster rushed into the zombie enclosure. Suddenly, it made a sharp turn, and a sharp triangular spike came out from under the carriage. It hit the zombie measured in the enclosure, setting off a bloody storm.

"Get out!"

At this time, a head poked out of the car and shouted at the bear and Xiao Xia: "hurry up! I'll cover you...".

"It's Lu team. Lu team has come to save us!"

The bear stood up supporting his body. Xiao Xia helped the shaking bear, "brothers, Lu team comes to save us, get out!"

Seeing the food in his mouth slip away from his mouth, the zombie roared angrily. Regardless of death, he bumped into Lu Ziming's hunting car. Some were torn by bullets, some were twisted into two sections by triangular spikes, and some were pierced by bone spikes stretched out from the inside as soon as they climbed into the carriage.

The bear and Xiaoxia rushed out of the gap torn by Lu Ziming with the disabled soldiers. Just as the zombie wanted to close the surrounding circle again, it was torn open by a fierce hunting car.

Lu Ziming drove the hunting cart around the disabled soldier, drove the zombies back again and again, attracted the attention of the mutant zombie to himself, and drove in a ring direction with the mutant zombie.

Xiao Cao jumped down from a building that looked cool like a villa and scolded: "Xiao pan took revenge for his own business and was almost killed by his gunfire. When I go back, I must let him play mahjong with me for three days and nights.".

Lao he came out of the building with his pants and said, "sleeping trough, such a beautiful toilet, is probably the legendary five-star pit!"

"Why envy? When we go back, build your house like this. In the future, we will go to your house to use the toilet every day!"

The two had fun in their hard work. They had already been scarred. If it hadn't been for the shelling just now, they might not have been able to rush out of the zombie encirclement. But this is to let them take a few more breaths. A flood of zombies poured in from all directions and surrounded their troops. If Lao Qian hadn't replenished some ammunition with [blink], I'm afraid he couldn't even hold on now.

"I didn't expect to kill more zombies today than last time. It seems that this zombie really doesn't want to let us both go..." before Lao he's finished, the zombie launched a new attack.

Xiao Cao looked around. Except for the high-grade pit that can be used as a villa, there was no cover. The open environment made the attack of zombies more convenient. There was really no way to escape. "Take another sip. I'm afraid there won't be such a good cigarette below.".

Lao he seldom smokes, but at this time he took half a cigarette handed over by Xiao Cao and smoked, "zombies seem to have evolved again. This zombie evolution is different from ordinary evolution. Have you found that the defense of low-level zombies has at least doubled, and they really play the role of cannon fodder..., the future war is becoming more and more difficult to fight".

"This is the second evolution of zombies that team Lu said last time! Unexpectedly, we met?"

"The last time I heard Lu team talk about natural selection, I thought Lu team was worried. Now it seems that zombies are more and more social and organized. They know their weak links and start to evolve. This is probably secondary evolution!"

Lu Ziming did not propose secondary evolution. A biology professor in Chiyou space put forward a bold hypothesis to speculate on the law of zombie development. He predicted that zombies would be completely destroyed by humans and dark creatures in about ten years if they did not evolve. If zombies were intelligent and failed evolutors, they would find a new evolutionary path, This is the theory of secondary evolution.
