After more than half a month of hard work, the sonic weapon specially designed to deal with those animals that may carry the virus has finally been successfully developed.

However, it was a bit surprising that during the test, it was found that this ultrasonic weapon can not only disperse those animals that may carry the virus, but even directly destroy the central nervous system of zombies.

It seems that the central nervous system eroded by the virus is countless times more brittle than the central nervous system of normal humans, and it is easy to be directly destroyed by the same frequency vibration caused by ultrasound.

It is enough to easily destroy zombies from a distance of 100 meters, even the zombies behind the thick walls can be destroyed by Chisong.

With the blessing of this new equipment, the zombie removal speed has been increased dozens of times, and the zombie removal plan of more than one million in Daegu City has also been put on the agenda.

Although there are only a few hundred people, the area on this side of the station is large enough, but considering the long-term development plan, it was decided to clean up the zombies in Daegu City.

——

After nightfall, a small team of fifteen people put on their weapons and got into their respective cars, ready to go to the city to clear the monsters.

Of course, this is the first time to act, and Zhou Bufan is also rare to go out with everyone, in case there is any mistake in this monster removal operation.

Seeing Zhou Bufan sitting in the co-pilot, Xiao Cui was very excited, this is the young man who was almost starved to death at the beginning, and then was found by Zhou Bufan and brought back to the base, and he is also one of Zhou Bufan's most fanatical fans.

"It's such an honor to be on a mission with you......"

"Urge classmates, don't be so excited and drive well."

"Yes."

Respectfully responded, but seemed a little speechless.

"But what don't you understand?"

“…… My lord, is it really okay for us to drive this car? ”

"Well, after the nerve center of the zombie is infected by the virus, although it still retains the ability of the five senses, it is indeed much lower than that of normal people, so it will appear that you can't see anything at night, and as long as you don't deliberately honk the horn, you can't hear the sound of the car engine with excellent silent effect."

"I see, thank you for your doubts."

"You're welcome, by the way, I heard that you have a good time playing model airplanes?"

"How can I say good in front of you, just a little, a little."

"Don't be modest, I need to study that virus recently, and I'll be busy, so you will be in charge of the reconnaissance drone in the camp in the future."

"Yes, thank you for your trust."

"Come on, young people, and try to one day bring the world back to normal."

"Understand, we will pass on God's blessings to every survivor."

The other party's words made Zhou Bufan a little speechless, and it felt a little strange to be regarded as a messenger sent by God.

The car moved forward unhurriedly and soon arrived in the city.

Because zombies always like to be in groups, they basically don't encounter zombies on the streets now, but once they encounter zombies, they will definitely encounter a large group, so after the convoy enters the city, it is also extra careful.

Even Zhou Bufan didn't dare to be careless, of course he wasn't afraid, but he was a little worried that something would happen to these people in a hurry.

However, this first monster removal task can be said to be quite smooth, with the assistance of night vision devices, the people in the car found the zombie group quite easily, and then the equipment started......

The zombies who were attacked by ultrasonic waves fell down in pieces and completely lost their breath of life, but in just a few minutes, they quietly cleared the group of zombies with more than 2,000 people.

The convoy slowly continued to move forward, and several devices mounted on the roof of the car also emitted ultrasonic waves everywhere, and where the convoy passed, the zombies on both sides of the street were completely emptied, and even many zombies trapped in the building were directly removed.

The task of clearing monsters was indeed smooth, but it took more than an hour to complete the removal of all the zombies in one block, and when I was about to move on to the next block to continue clearing, the intercom in my waist pack suddenly sounded......

"Rest assured that everything is in order, we are safe." Picked up the walkie-talkie and said.

"Zhou, you're coming back soon, there's something wrong with the camp." Min Zhi's voice seemed a little hurried, and he even heard gunshots, which was obviously not an attack by the zombie group.

"Okay, I'll go back right away, take care of yourself."

"You also have to be careful, this time the enemy is not zombies, all of them have guns." After saying that, he ended the call, obviously too busy fighting to continue.

It's really unclear why there would be an enemy attacking the camp inexplicably, and it stands to reason that the survivors of this zombie-infested world should work together to make a better choice.

However, the battle has already taken place, and the group of enemies who don't know where they came out can only be said by rushing back to clean up first.

"Today's mission is over, I'll go back first, and you wait for the gunfire to stop before you go back to the camp." After explaining to the team, he got out of the car directly and started the light body technique, and disappeared into the night in an instant at a speed of nearly 150 kilometers per hour.

——

There were not many people attacking the camp, about fifty people, but all of them had automatic rifles, and even a few people were carrying RPG bazookas, and Zhou Bufan, who saw this scene, was really taken aback.

Fortunately, it was in time, otherwise Min Zhi would most likely be killed by this bazooka, and a chain of lightning instantly bloomed from the palm of his hand, and several people fell straight to the ground......

Although the others reacted, as if there was an enemy attacking, they didn't have a chance to turn the muzzle of the gun at all, and they didn't even see the figure clearly, and the back of the head was already attacked and instantly unconscious.

A few people in the distance saw that the momentum was not right and immediately got in the car and fled, of course, these people were deliberately let go by Zhou Bufan, in fact, if they didn't want to let go, these people didn't even have a chance to get in the car.

A tracker was thrown out of his hand, and it was directly attached to the car that was fleeing quickly.

The Divine Sense glanced around, and after having subdued all the intruders, he picked up the walkie-talkie.

"Zhou, but you're back, I saw lightning just now?"

"Yes, the enemy has been stunned by me, and I won't wake up for a while, but for the sake of safety, you should bring some people over and tie them all up first."

"You're leaving again?"

"Well, I'll have to go to this group's lair to see what's going on."

"You can still be hurt by firearms, it's too dangerous to just go like that...... Can you not go alone? ”

"It's easy to startle snakes when there are too many people, I have to investigate the quality of this group of people, if this attack is just a misunderstanding, then it can be discussed, if it is a group of ruthless characters who kill people without blinking, then I will slaughter these people, so as not to keep them to harm others."

“…… You must come back safely. ”

"Don't worry, I'll be careful."

After saying that, he got into a car directly, and the car driven by this group of people of unknown origin caught up with the fleeing car from a distance......
