Chapter 1155 Open the City Gate Secretly?

"City Lord, where are we going now?" asked the optimistic Xiaohan standing at the door of the greenhouse.

She was much stronger than Li Yu had imagined. She had seen Li Yu kill people with her own eyes, but she was still able to remain relatively calm.

A trace of surprise flashed in Li Yu's eyes, but he thought it was reasonable.

After all, Xiaohan had followed Song Min before, and they had experienced some things together, and even witnessed Song Min's lingchi of Zhou Sheng.

"Let's take you to the residential building opposite first, find a place for you to stay, and when the situation gets better, you can return to the inner city." Li Yu thought for a while and said to Xiaohan.

Then he glanced at his uncle and nodded.

Pushed the door open.

When the two came out, he looked at the people in the greenhouse with cold eyes.

His eyes made the people inside feel scared, as if they were falling into an ice cellar.

"Let's go!" Li Yu turned and left.

The distance from the greenhouse to the residential building in the outer city was very close. Li Yu shone the searchlight over, but he could still only see one or two meters away.

After walking two steps, he saw lights on the opposite side, and several figures walked over.

Before Li Yu opened his mouth, a voice came from the opposite side: "Who are you?"

"It's me." Li Yu said loudly.

"It's the city lord."

"The city lord is coming out."

There was a discussion on the opposite side, and with the sound of footsteps, the faces of these people appeared in front of Li Yu.

"City lord, we are going to the outer city wall now." He Chao, the leader, said happily after seeing Li Yu.

Li Yu nodded, then pointed to Xiaohan on the side, and said to He Chao: "Send someone to take her to the outer city residential building."

"Okay, A Guang, you take her in."

A Guang walked to Xiaohan with a flashlight, and then took her to the outer city residential building.

Watching the two people's backs disappearing in the thick fog, Li Yu nodded, and then continued to say to He Chao:

"When I passed by the greenhouse just now, I heard that there was something wrong with the greenhouse of the cooperative personnel. You will send a message to Lao Luo later and ask him to take people to watch the greenhouse."

"Ah? They dare? Rebellion?" He Chao was angry and surprised.

He originally thought that killing so many people before would scare these people, but he didn't expect that someone would dare to make trouble at this critical moment.

It seems that the killing is not cruel enough.

Li Yu continued: "The two arrogant people have been killed on the spot by me, but this matter must be thoroughly investigated."

As he said, he walked towards the outer city wall.

There are large searchlights on the outer city wall, which can illuminate the situation a hundred meters away.

But in foggy weather, even the wall cannot illuminate the ground from a distance of thirty meters.

Li Yu and his friends on the ground can only see the dim lights.

He Chao frowned and followed Li Yu and his uncle.

Tap tap tap!

Climbed up the outer city wall.

Li Yu saw Master Yang standing next to the liquid nitrogen sprayer, wearing an oxygen mask and gloves, spraying outside the city.

As the liquid nitrogen was sprayed, the fog outside the wall dissipated at a speed visible to the naked eye, and a drizzle began to fall.

Liquid nitrogen has a very low temperature and is very volatile. When it is sprayed in the air, it will expand rapidly and absorb a large amount of heat, causing the surrounding temperature to drop sharply, and the water vapor in the air will quickly condense into rain.

Li Yu stood by the wall, watching the drizzle outside the outer city wall. Liquid nitrogen is colorless and odorless. In the fog, such a wonderful scene was formed:

There was a small open area in the thick clouds, and there was thick fog above, on both sides, but only in this area was there a drizzle.

Like a dream.

With the illumination of the searchlight, they could see the situation on the ground outside the wall when standing on the wall, and the farthest they could see was dozens or hundreds of meters.

After the liquid nitrogen was sprayed, it drifted farther with the wind, but the fog kept coming from all directions.

This was not a regional fog, and the coverage area was extremely wide, so once the liquid nitrogen spraying stopped, the fog next to it would fill in.

"Huh——"

Li Yu saw the situation outside the wall. Now the fog had just started, and no zombies had come outside the base for the time being.

After all, usually when they entered and exited the camphor tree base, they would deal with the zombies they saw.

So within a five-kilometer radius of the camphor tree base, as long as there was no heavy rain, there were few zombies.

"City Lord." Master Yang, wearing an oxygen mask, said quickly after seeing Li Yu.

The outer city wall, because the sprayed liquid nitrogen would blow onto the wall to some extent, so the wall formed a piece of blank area without thick fog.

It was just that these blank areas were a bit fantastic, only two or three meters high.

There was thick fog above.

It seemed as if the sky was right above their heads, making people stop and admire.

Li Yu nodded to Master Yang, and then walked straight to the duty room.

In the duty room.

Second uncle, Li Hang, Li Tie and others were all here.

"Second uncle."

Li Yu pushed the door open and said to his second uncle.

"Xiao Yu."

"City Lord."

"Big Brother."

He Chao, who came in last, quickly closed the door to prevent the fog outside from blowing in.

The heater was turned on in the duty room to dry the moisture in the duty room.

Li Yu turned off the flashlight in his hand, and then said to his second uncle:

"What's the situation now?"

His second uncle frowned and replied:

"This time the heavy fog is coming fiercely. Although liquid nitrogen has been sprayed now, the effect is limited. The range that can be covered is only around the spray area. The zombies have not come yet. I am afraid that when the zombies come, they will form piles like during heavy rain. ”

"Is liquid nitrogen still being produced?" Li Yu asked.

"It's still in labor, Kong Shuang is watching over there." The second uncle replied.

Li Yu thought for a while and continued:

"In this way, you ask half of the combatants on the inner and outer city walls to turn the liquid nitrogen sprayers and spray them all in the direction of the base. You can't see anything in the base now, and there will be problems with personnel deployment and transportation. This won't work. ”

The second uncle nodded, then picked up the walkie-talkie:

"Attention all combatants on the fence, the single-numbered liquid nitrogen sprinklers continue to spray outside the base, and the even-numbered liquid nitrogen sprinklers spray in the direction of the base."

Sizzling——

"receive."

"receive."

The voices of those people kept ringing on Uncle Er's walkie-talkie.

Li Yu looked at the military radio and asked his second uncle:

"Is there heavy fog over there in Oil City?"

The second uncle hurriedly said: "I just finished talking to Ju Tianrui before you came. There is no heavy fog there yet. In addition, there is no fog over the federal garrison in the north, nor over Lao Xie's side."

Li Yu frowned and thought to himself: Maybe it hasn't blown there yet.

Outside the duty room.

The uncle stood on the wall, frowning.

He had just notified Lao Bi in the outer city and asked him to bring people up quickly for support. Now Lao Bi is probably still on the way.

It takes people to spray liquid nitrogen, but it also takes people to guard the fence.

The zombies haven't come yet, so the manpower is not tight, but if the zombies come, there will be some trouble.

Although a mobile gate knife is installed on the fence, which can effectively clean up zombies, if the mobile gate knife fails and no one notices it on the fence, the zombies will inevitably pile up as time goes by.

Therefore, there must be someone on guard on the fence.

"Xiao Shunzi, you can't do this, try to spray as far away as possible, and tighten it here." The uncle saw Xiao Shunzi spraying all the liquid nitrogen under the wall, so he quickly reminded him.

"Oh, okay." Xiao Shunzi quickly tightened the liquid nitrogen injection port.

Clouds and mountains are surrounded by fog.

The entire Da Zhangshu base was shrouded in fog.

Li Yu walked out of the duty room and walked around the wall.

As liquid nitrogen is sprayed, the buildings near the wall gradually become clearer.

But it's not enough. The places further away from the wall in the city are still invisible.

Li Yu frowned and suddenly thought of a way.

Since you can't spray in the city, try using sprinklers to spray into the sky.

If you can't see anything in the thick fog, just moving the knife will definitely not work.

In addition to the threat of external zombies, there is also pressure from within the city.

It's easy to get into chaos in the base when you can't see anything.

At this time, it is easy for people's hearts to breed evil. Even if they do some bad things, no one can see it.

Li Yu never tests human nature, because human nature is the least able to withstand the test.

He returned to the duty room before even circling the outer city wall.

Contact Lao Lu urgently and ask him to take someone to drive to the factory, fill the tank with liquid nitrogen, and spray liquid nitrogen in the base.

After receiving Li Yu's order, Lao Lu called a few people and hurried down from the wall, taking a tank of liquid nitrogen with him when he left.

As he walked, he sprayed towards the sky.

Only in this way can you see the ground clearly.

The air was humid, and small droplets of water fell wherever the liquid nitrogen was sprayed, forming a light drizzle.

Lao Lu got off the fence and soon became soaked to the skin.

The clothes stick to the skin, making it sticky and uncomfortable.

But he no longer cares about that much.

呲呲呲——

Liquid nitrogen was sprayed in the air, and light rain continued to fall.

Lao Lu and others could not run, so they could only walk quickly to the garage in small steps.

ten minutes later.

He arrived at the garage and shouted at someone to get the car out, all the while spraying liquid nitrogen from his hand.

If too much liquid nitrogen is sprayed, the air will be easily deprived of oxygen.

But this is not a closed environment, the air is circulated, so there is no danger of suffocation, but it will make people feel a little uncomfortable.

Boom boom——

The vehicle starts.

Lao Lu did not sit in the passenger seat, but sat directly on the roof of the car.

This is very dangerous, but if they want to drive, they must clear a visible area in front of them.

No matter how slow the speed is, if someone in front of you does not see you, you will still be easily hit in this invisible environment.

Lao Lu sat on the roof of the car and kept spraying liquid nitrogen.

Then he said to the team members in the car: "Turn on the horn to warn the people in front."

"But, Captain, what if we attract zombies?"

Lao Lu couldn't help but scolded: "If you don't turn on the speaker, won't the zombies be attracted? There are so many people in our base and the popularity is so strong, the zombies must be on their way here. Stop talking nonsense and turn on!"

drop--

Vehicles honked and vibrated.

Drive slowly towards the factory at the slowest speed.

And in the outer city.

Qingyang heard the horn sound outside and leaned against the window to look outside.

However, I still can't see anything.

One hand pulled Qingyang's sleeve.

The room was heated and lit, so it was clear.

Li Yuan pulled Qingyang's sleeve and said, "Why don't you go to the wall to help? There's probably a shortage of people there. My eldest brother must have gone to the outer city wall. Go over there and I'll talk to him on the intercom."

Qingyang hesitated and said, "What about you?"

"I'll stay here. It's safe. Don't worry." Li Yuan said.

"Okay." Qingyang nodded.

He walked towards the door, then stopped and said to the two senior brothers in the room, "Big Brother, Second Brother, please help me take care of Xiaoyuan."

"Okay." The tall and thin Taoist nodded.

But the short and fat Taoist Qingxiao stood up and said to Qingyang, "I'll go with you."

Qingyang thought about it and didn't refuse.

After all, Big Brother Qingxiao's skills are better than his. Although he is fat, his fighting power is amazing.

Qingyang glanced at Li Yuan, and Li Yuan nodded at Qingyang and gave him a look that said you should rest assured.

Then

Qingyang and Qingxiao walked out.

They didn't have flashlights, but it was still easy to walk in the corridor, at least there were lights.

But after leaving the residential building, they could only rely on the scattered street lights to guide the direction.

"Come with me." Qingxiao pulled Qingyang.

He had amazing hearing and a good memory. Even though he couldn't see around, he and Qingyang walked to the foot of the wall with his familiarity with the outer city.

Under the wall, it was drizzling due to the spraying of liquid nitrogen.

In addition, there was a street lamp by the door,

Although it was hazy, at least it could be seen clearly.

Suddenly.

He saw a person standing by the gate of the first outer city.

This person seemed to be studying how to open the gate of the first outer city, and was still smashing it with stones.

Tat tat tat!

"Keep your voice down." Qingxiao said to Qingyang.

Then he slowly walked over there.

The two slowly approached, approaching the person under the gate.

Qingyang and the others watched this person in the rain.

He tried to smash the door open with a stone. After smashing for a long time, he looked around with a grin, as if looking for the switch to open the door.

Qingxiao's eyes flashed with a trace of thought.

There is only one way to open the gates of the inner and outer cities.

That is to open it through the mechanism from the wall. It cannot be opened from below.

Moreover, the gate of the big camphor tree base is not good-looking, but it is very strong. It is made of steel plates of dozens of centimeters and poured with concrete in the middle.

If it is not through the mechanism, ordinary people can't open it at all.

But this person wants to open the door at this time. Going out is the first Weng City. If the door of the first Weng City is opened, it is equivalent to opening it.

This person has bad intentions.

Qingxiao's brain is working quickly.

He said to Qingyang next to him: "You watch here and see if there are other accomplices."

"Big brother, be careful." Qingyang said with concern.

"It's okay."

Qingxiao rushed over and asked sternly:

"What are you doing!?"

Boom!

Like a flash of lightning, it exploded from the head of the man at the door.

He shuddered all over and ran back.

Although it was raining in this area, there was thick fog dozens of meters away.

Once this man ran into the thick fog, Qingxiao could not catch up with him.

Swish!

Although Qingxiao was fat, he was amazingly fast.

Before the man ran into the thick fog, he caught him.

He knocked him out with one punch and dragged him back to Qingyang like a dead dog.

Qingyang saw that the senior brother knocked the man out directly, so he said awkwardly: "Are you mistaken?"

"Simple! You are stupid!"

Qingxiao snorted coldly and said: "He smashed the door and ran away when he heard me calling him. He must have something wrong. Do you know this person?"

As he said that, he turned the man's face over.

Qingyang looked at him for a long time, shook his head and said: "I don't know him."

"Let's take him to the city lord."
