Chen Qi and Sun Xiaowan looked at the purgatory-like scene in front of them, and their faces were not very good-looking. Under such an overwhelming attack, it was difficult for the Axes to hold their ground.

If they did not have special means, it would be a tragedy and it would soon be over.

Walls of fire were constantly extinguished by monsters that followed one after another, and many defenders were overwhelmed by the overwhelming monsters before they could retreat.

They watched as their heavy machine guns and flamethrowers spewed furious flames at batmons flying in the sky, many of which were strafed down, dropped in the hordes of monsters, and turned into piles of bones.

The iron fence and the fire wall defense ring on the ground are constantly shrinking, and it is estimated that they will soon be able to approach their command center.

It was a tall fortress-like structure, with heavy machine guns and large flamethrowers, arranged on that fortress, guarding their last territory.

On the periphery of the fortress, there are also some people, either armed with bows and arrows, or armed with careful flamethrowers, or armed with swords, who are also fighting against the monsters.

The display is so cruel, there are a large number of monsters in all directions, they just want to escape, and there is nowhere to escape, and many people still haven't figured out why these massive monsters of different kinds will suddenly unite and attack their base.

"Eleven, is that monster still summoning them?" Chen Qi asked.

"Well, it seems to be in a hurry, as if it is afraid of something."

"Scared?" Chen Qi was a little surprised, because he was not at the scene, he couldn't understand this

"Well, it's just scared, its body is trembling." Chen Shiyi said affirmatively.

"What is there to scare it?" Chen Qi couldn't understand.

"Seventh brother, why didn't you say that this group of people from the Axe Gang gave up the base and fled?" Sun Xiaowan asked suddenly.

"You're saying they might have something else to do?"

"If our guess is true, they really bred such a powerful monster, and other people don't know how powerful it is, but that Dr. Leng must know. I wonder if there's no reason for that Dr. Leng to think that this monster is more important than his own life. If necessary, she will definitely kill this monster, isn't she proficient in making drugs? ”

"But she didn't, that means she must still have hole cards in her hand." Sun Xiaowan voiced her guess.

"And this kind of hole card will make this powerful monster feel scared, what could it be?" Chen Qi was also guessing, but after guessing for a long time, there was no result.

In this situation, they just want to save people, but they can't do it, the first is that there are few people, and the second is that there are no heavy weapons in their hands, if they just rush over, it is no different from looking for death.

If you want to save people, you have to find a way, and you can't do nonsense, otherwise not only people can't be saved, but they will also take their own lives.

Just when they were still guessing, the last third firewall of the Aokido base of the Axe Gang was finally broken through by the monsters, and countless monsters rushed forward with smoke and fire.

At this moment, several things like satellite towers suddenly appeared in the base of the Axe Gang, like a large horn, with a small circular ball connected by a tripod in the middle, and the ground of the big horn, as well as thick wires.

"What is this?" Chen Qi and Sun Xiaowan are a little strange, are these newly invented weapons?

At this moment, those people turned on the power supply, only to hear a sudden soft buzzing sound in the air, and then there were many buzzing sounds, like sound waves, radiating outward in a circle, making people feel bored and want to vomit.

"Seventh brother, I'm so uncomfortable!" Xiao Eleven, who was on Chen Qi's back, suddenly hugged his head and said, looking very painful.

"It's an ultrasonic weapon, let's get out of here." Sun Xiaowan said.

In fact, she didn't need to speak, Chen Qi was already running wildly with the iron plate car.

"It's okay, Brother Seven, I'm not uncomfortable." After retreating a few hundred meters, Chen Shiyi spoke.

Sound waves have a distance, and beyond this distance, they will not have an effect on people.

Chen Qi looked at the surrounding environment, and saw that about fifty meters in front of him, there was a tall building, and above that, he could just see the situation of the Axe Gang.

"Let's go up there." Chen Qi pointed to the top and said to Sun Xiaowan.

"Good!"

So they climbed up and stood on the roof, and sure enough, they could see what was going on on the side of the Axe Gang.

Those things like WeChat signal towers are really very powerful, and I saw that the monsters in front of them were rolling their bodies, in pain, and they couldn't even escape, and even those bat monsters in the sky fell down one after another.

Chen Qi and Sun Xiaowan were both dumbfounded.

"They have such a powerful thing, why didn't they take it out earlier?" Sun Xiaowan said indignantly, "Killed so many people. ”

"I guess these ultrasonic weapons, which may have a useful life, will not be taken out until the last critical moment. And this is a trick to hurt a thousand enemies and eight hundred to oneself, and you see that their people are also rolling on the ground. ”

Sun Xiaowan looked at it fixedly, isn't it, those people in the Axe Gang are also covering their ears, or kneeling on the ground, or rolling on the ground, they are all vomiting wildly, bleeding from their seven orifices.

"It's a game of who can handle it. Whoever can't bear it first loses. Chen Qi said lightly.

At that moment, there was a new change in the field, and I saw that in the northwest direction, suddenly a helicopter flew over the fortress and landed.

A few strong men with headphones came out below, led by a young woman, pushing a large suitcase, and moved to work in a helicopter.

"They're going to get that monster away!" Sun Xiaowan said.

"No wonder that monster is so scared." Chen Qi also suddenly realized.

"That woman should be the so-called Dr. Leng." Sun Xiaowan said.

Chen Qi looked at her carefully, as if he wanted to imprint the image of that woman deeply in his mind.

The group boarded the helicopter and flew away with a puff.

Just as they took off, the supernatural wave weapons on the ground suddenly snapped a few soft sounds, and a cremation came out, and the buzzing sound stopped abruptly.

The monsters that were still rolling just now were killed and injured, and the thick corpses were almost piled up into a small mountain, which made people's scalps tingle to see.

However, there were still a large number of okay guys, and they actually fought each other with red eyes, turning the venue into a new Shura field.

"These ultrasonic weapons will have strong sequelae, which will not only destroy their sanity, but also stimulate their ferocity and bloodthirstiness." Chen Qi looked at it for a while, then said with a shudder.

"What a vicious woman!" Sun Xiaowan gritted her teeth and said, "She abandoned everyone. ”

"In fact, from the beginning, she didn't care about other people's lives, she only cared about her own results, and abandoning them was inevitable." Chen Qi said lightly.

The monsters were already terrifying, but now that they are crazy, they become even more terrifying, especially those walking corpses and bat monsters, who are stimulated the most, almost seeing anything, killing anything, and the scene becomes a Shura field.

Those people in the base of the Axe Gang, who had lost the strength of ultrasonic weapons, had been injured by their own weapons just now, and had already become weak and weak, and they could still resist the attacks of these monsters, and soon, the screams rang out one after another.

After a while, there was a loud bang from inside the fortress, and then, the entire quarantine area was turned into a sea of fire, and they actually resorted to the same fate.

Countless monsters were swallowed up by the huge explosion without snorting, and some bat monsters screamed and tried to escape, but were soon engulfed in the skyrocketing flames.

Chen Qi's face was a little ugly, under such a huge explosion, even if there was any peerless medicine, it was blown up, how could he still find any antibiotics?

Sun Xiaowan's face was also ugly, under such a huge explosion, it was estimated that it would be difficult for her companion to save his life, and he might have died when the disaster broke out.
