"Xiao Shunzi, you can't do this. Try to spray it further away. Tighten it here." My uncle saw that Xiao Shunzi sprayed 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 mist.

The entire camphor tree base is shrouded in fog.

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

With the spray of liquid nitrogen, the buildings near the fence gradually became clear.

But it is not enough. The place in the city that is far away from the wall is still invisible.

Li Yu frowned and suddenly thought of a solution.

Since you can't spray it in the city, try using a sprinkler truck to spray it into the sky.

In the thick fog, if you can't see anything, it will definitely not work by just moving the switch knife.

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

When nothing can be seen, it is easy to get messy in the base.

At this time, evil is easily aroused by human hearts, and no one can see it even if they do something bad.

Li Yu never tests human nature, because human nature is the most untestable.

Before he could walk around the outer city walls, he returned to the duty room.

I urgently contacted Lao Lu and asked him to take someone to drive to the factory, fill it with liquid nitrogen, and spray it with liquid nitrogen in the base.

After receiving Li Yu's order, Lao Lu called a few people and quickly got off the wall. When he left, he also brought a can of liquid nitrogen.

While walking, spraying into the sky.

Only in this way can you see the ground clearly.

The air was wet, and small drops of water fell from the places where liquid nitrogen was sprayed, forming a drizzle.

Lao Lu got down from the wall and soon his whole body was soaked.

The clothes stick to the skin, making them feel so sticky.

But he no longer cared about that much.

sir-

Liquid nitrogen sprayed in the air, causing light rain to continue to fall.

Lao Lu and his men couldn't run, so they could only go to the garage at a speed of small steps.

Ten minutes later.

He arrived at the garage and asked someone to drive the car out, while the liquid nitrogen in his hand kept spraying.

If too much liquid nitrogen is sprayed, the air will easily become hypoxia.

But this is not in a closed environment and air circulation, so there is no risk of suffocation, it just makes people feel a little uncomfortable.

Boom--

Vehicle starts.

Lao Lu did not sit in the co-pilot, but sat directly on the roof of the car.

This is very dangerous, but if they want to drive, they must clear out a visible place ahead.

Even if the car speed is slow, if someone does not see it in front of you, you will still be easily hit in such an invisible environment.

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

Then he said to the team members in the car: "Open the horn and warn the people in front of him."

"But, captain, what if it attracts zombies?"

Lao Lu couldn't help but curse, "Will the zombies be attracted if you don't turn on the horn? There are so many people at our base and so popular. The zombies must be on the way to come. Don't talk nonsense, open it!"

drop--

The vehicle whistles and vibrates.

Drive slowly towards the factory at the slowest speed.

And in the outer city.

Qingyang heard the sound of horns outside and leaned against the window and looked out.

However, there is still nothing to see.

He pulled Qingyang's sleeve with one hand.

The room has turned on the heating and the lights, so you can see clearly.

Li Yuan pulled Qingyang's sleeve and said, "Or, you go to the wall to help. There is probably a shortage of people there, so my elder brother must have gone to the outer city wall. If you go over, I will tell him on the walkie-talkie."

Qingyang hesitated and said, "What about you?"

"I'm just staying here, it's very safe, don't worry." Li Yuan said.

"Okay." Qingyang nodded.

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

"Okay." The tall and thin Taoist priest nodded.

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

Qingyang thought about it but did not refuse.

After all, the eldest senior brother Qingxiao is better than him. Although he is fat, his combat power is amazing.

Qingyang glanced at Li Yuan, and Li Yuan nodded to Qingyang and gave you a look of peace of mind.

Then.

Qingyang and Qingxiao walked out

They don’t have flashlights, and it’s easy to walk in the corridor, at least there are lights.

But when you walk out of a residential building, you can only guide the direction with sporadic street lights.

"Come with me." Qingxiao pulled Qingyang.

He has amazing ears and a good memory. Even though he can't see it around, he and Qingyang still walked to the foot of the wall with his familiarity with the outside city.

Under the fence, it was raining lightly due to the spray of liquid nitrogen.

This chapter is not over, please click on the next page to continue reading! Plus there is a street light next to the door,

Although it is hazy, it can be seen clearly at least.

Sudden.

He saw a man standing next to the gate of the First Outer City.

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

Step by step!

"Speak quietly." Qingxiao said to Qingyang.

Then slowly walked towards the other side.

The two of them slowly approached and approached the man under the gate.

Qingyang and the others were watching the man in the rain.

He tried to smash the door with a stone. After a long time, he looked around and seemed to be looking for the switch to open the door.

A trace of thought flashed in Qingxiao's eyes.

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

That is, it is opened from the wall through the mechanism, and it cannot be opened just below.

Moreover, the gate of the Dazhang Tree Base is not good-looking, but very sturdy. It is made of steel plates worth tens of centimeters and is watered with concrete in the middle.

If it is not passed through the agency, most people cannot open it.

But this person wanted to open the door at this time, and when he went out, he was the First Wengcheng. If he opened the door of the First Wengcheng again, it would be like opening it.

This person has bad intentions.

Qingxiao's brain is running fast.

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

"Senior Brother, be careful." Qingyang said caringly.

"fine."

Qingxiao rushed over and asked sternly:

"What are you doing!?"
