The gunfire on the underground square continued, and the war insects besieged by the second wave had climbed down from the dome, climbed over the corpses of their companions, and bravely moved forward.

Hao Zhi found that the body of the second wave of war insects was slightly blue. Unlike those guys who had been destroyed before, they moved more slowly and seemed to carry more weight.

Sure enough, those guys climbed over the trench composed of insect corpses in a fan face, and then they didn't move forward any more. Instead, they put their heads down, and the hard armor on their backs stood up like a shield!

"What kind of posture is this? Is there anything fishy?" Hao Zhi quickly looked at it and saw that song Xiaojia's Ying made bullets hit the enemy's hard armor, emitting sparks and a burst of green smoke. Only when the light blue smoke dispersed did he see that their hard armor had not been damaged at all!

"Their body structure is different from the one in front. It seems harder! Even our Yingjia bullets don't work!" Wang Yanke saw a similar scene and quickly reminded song Xiaojia, "be careful, they're not afraid of your bullets!"

"It seems that these guys also know how to improve their density and hardness to resist!" before Hao Zhi could figure it out, he saw more than a dozen bright yellow lasers suddenly shoot out from their heads and insert them into the soldiers' ranks like more than a dozen sharp lightsabers. In an instant, the crowd burst into flames and a burning smell soared, The smoke made Hao Zhi cover his mouth and nose with his hands.

The explosion caused by the laser caused chaos in the dense ranks. Some soldiers at the center of the laser attack were melted on the spot, even those who scratched the edge were injured, and some of the periphery were severely burned and screamed.

"Spread out! Spread out! Don't get together!" Song Xiaojia shouted, pushing the soldiers around her with her hand, so that everyone didn't get together.

But it was too late. The laser beams were fired like raindrops. In this unobstructed square, the bullet speed of the earth soldiers could not catch up with the agility and accuracy of the speed of light. A large number of soldiers were burned to death. The rest had no ability to fight back except to crawl and avoid.

While talking, the mechanical beetle had spread from under his feet and immediately covered most of the base square. Song Xiaojia shouted at the top: "Hao Zhi, almost, hurry!"

Hao Zhi gets the news and knows it's time to do it himself!

He winked at Yan Ke, the king of dianle, and four people fell from the sky. Due to the early injection of strength medicine, Lele suddenly spread PINK METAL wings in mid air, falling gently on the back of a war bug like an angel falling into mortal dust. Then Cang clattered out his war knife and swept down, and the beetle's head flew out, The body tilted heavily to one side.

This is a tactic that several people have repeatedly studied before. After fighting with these mechanical warfare insects for several times, they know that they can't take advantage of long-distance combat and weapons. Fortunately, although they are hard, they are not sensitive enough.

As long as they fight close and drill into the swarm of insects, Hao Zhi can make the other party overwhelmed. Their laser emission can't aim. Even the emission will hurt their own people. Stepping on and biting alone can't help their fast figures.

Therefore, song Xiaojia first attracted the enemy's attention. Hao Zhi hid on the patrol overpass in mid air and waited until the right time to participate in the battle.

Hao Zhi leaped down and fell into the swarm with a bang. He squatted down, supported the ground with one hand, pulled out the sabre on his back, swung a big windmill, swept thousands of troops, and instantly cut down several war insects around him. Those guys didn't prevent someone from attacking from above, and the swarm immediately made a mess.

Hao Zhi took the opportunity to kill and chop all the way with a single hand knife. Wherever he went, it was like chopping melons and vegetables. The insects flew sideways and the parts burst out. Several people cut the flood of war insects in half from the middle and leaned towards song Xiaojia. The war insects behind were surprised and didn't dare to rush forward for the time being.

Zhang Dian Dian doesn't have much experience in fighting and won't fight. She will also find a way. When she falls into the swarm of insects, she will move forward with the sword with the tip facing up and the blade facing forward, like carrying a big flag. She closes her eyes and runs without turning a corner. She will open all the war insects passing by all the way. When her head hits the wall, she will look back, The felled war worm even poured out a way to the left and right.

Several people fought this time, and some people in the escape passage behind them went in. There were five or six hundred people who couldn't squeeze in. The remaining soldiers forgot to run for their lives. How have they seen such a battle?

Now everyone is silly. I'll play a song. Why don't you swing a knife and fight with a gun? The opponent is still those huge metal war insects!

They didn't understand the powerful medicine injected by Hao Zhi. They saw human figures flying, jumping up and down, acting like spirit apes and tigers. It was like watching a movie. They killed a large number of mechanical beetles in the blink of an eye!

"Are these human beings?" the people couldn't help asking a question.

Soon, the rest of the war insects also retreated. When Hao Zhi wanted to oppress his opponent again, he found that those thick armor war insects with light blue halo had come up in the second row. He could see clearly when he was up. Those guys' thick armor couldn't even break through Ying bullets. He didn't know what material it was.

Is it the alloy of Ying and something else?

Did aliens get the technical secrets of Ying and tungsten steel alloy?

"But even if they are Yinggang alloy like war knives, I'll fight to see if your alloy is hard or my war knives are sharp!"

Thinking of this, Hao Zhi jumped up in the air, clenched the handle of the knife with both hands, and chopped his head against the first thick armor and insect. As soon as the guy lowered his head, the hard armor on his back stood up, and did not dodge against Hao Zhi's knife!

As soon as the blade touched each other, Hao Zhi only felt as if his strength had been sucked in. Then he rebounded violently. With a "buzzing" sound, the war knife took off his hand and was ejected more than ten feet away. A soldier was watching the war, but saw a big knife chopping at him and scurrying around. Hao Zhi's war knife "clattered" and fell to the ground and slid out a long way.

"It's an energy shield!" Wang Yanke shouted to Hao Zhi, "are you still stunned? Run!"

Hao Zhiben thought that even if he didn't cut and hang the Yinggang sword, he could seriously hurt the other party. Unexpectedly, it was this result. He was in a daze. After listening to Wang Yanke's cry, he realized that he had no weapons.

The laser transmitter on the mechanical beetle's head flashed bright yellow. Hao Zhi suddenly sidestepped and wiped his arm. Fortunately, he was protected by armor, but he also felt the hot temperature, and the outside of the armor was blackened.

Hao Zhi turned and ran away, but he felt a dark shadow flying in front of him. It was song Xiaojia, a girl who didn't believe in evil. She flew across like a shell and stabbed her with her hands. However, she was bounced back by the other party's energy shield and hit the wall of the base heavily, and even the steel plate protecting the wall was concave.

However, song Xiaojia's strange power was invincible. Although she was bounced back, the impact also pushed back the war worm on the opposite side, which gave Hao Zhi some time to escape. Otherwise, no matter how fast he ran, he couldn't prevent a laser from hitting behind the other party, and he would be seriously injured if he didn't die.

After this toss, the rest of the soldiers basically fled into the tunnel. In nearly an hour, most of the more than 20000 people got into the escape passage. Hao Zhi knew that the task of covering the dead was completed, so he didn't intend to fight.

The war insects pouring in from the breach of the base are like a tide. They can't be killed. Moreover, this new type of war insect with protective shield can't find weakness for the moment and can't fight at all.

So he took a few steps back, picked up his sword and shouted to Wang Yanke: withdraw!

"Got it!" Wang Yanke crossed his sword, blocked a laser attack, and then ran back to the tunnel entrance quickly. At the same time, Diandian and LeLe had arrived. After entering the tunnel, Wang Yanke pressed the door closing key, and the two four or five meter high metal gates began to close slowly.

Fortunately, before the mechanical beetles in the distance behind had time to rush over, the thick armor war beetles in front of them blocked the attack. In order to increase their resistance, the war armor was very thick, so they moved more slowly. Before they had time to respond, the huge metal gate had been slammed shut.

"Hoo... This gate was specially made by the military factory by Xu zhe recently. It's all made of Ying steel alloy. Once it's closed, they can't attack again! Commander Xu still has foresight..." Wang Yanke breathed out and said that in fact, she doesn't need to breathe in and out at all, but her system simulates a human action.

"Chen, I always thought it would be safe to stay here. It seems that Xu Zhe is far sighted and thinks more than us!" Hao Zhi admires. "It's just a pity that the base is gone and I don't know where to live in the future!"

Wang Yanke pushed him behind him: "you think a lot. This is just the first step on the road of escape. We haven't got out of the enclosure. There are countless strange insects waiting for us out of the tunnel. I don't know what will happen in the future..."

"Let's go," Song Xiaojia held the rocket launcher behind her, tightened the strap, nodded, stepped on the falling daily necessities, toothbrushes, clothes, pots and pans, and ran to the depths of the tunnel
