The sealed building is a building that completely wraps the main building with glass and tape, just to prevent the occurrence of a poisonous storm, and the Eastern Theater has also suffered from the poisonous storm.

In addition to wrapping around the building, a purification device is also installed in the main vents, which uses a chemical reagent to absorb the radiant gas from the air, thereby reducing the amount of radiant gas that inflows when the building is ventilated.

Zhou Yan also followed the survivors and hid in the sealed building together, while also being in charge of the security management of one of the buildings, which is the responsibility of the police department.

Of course, when there was no Zhou Yan, the comrades in the police station did a good job, so he directly assigned the work of maintaining law and order to several police officers, and he was the shopkeeper.

The wind blows, rolling the rain cover of the cargo, and it rattles.

In front of the glass window on the third floor, Zhou Yan looked at the gloomy sky outside.

Some had nothing to do, expecting the rain to fall as soon as possible, and the radiant gas to be quickly washed away. It's just that the night has passed, the rain has not fallen, the sky is still cloudy, the concentration of radiation gas has further increased, once people are exposed to the outside, the skin immediately ulcerates, poisonous gas attacks the heart, and the serious is even more fatal.

They can only continue to be trapped in the sealed building and are not allowed to go out.

Fortunately, there are underground passages between the buildings, which are interconnected, including various material storage warehouses, and with the city wall, which are all interconnected, but do not affect normal life.

"I didn't expect the cold wave in Siberia to move south, which would have such a big impact on us, and now the concentration of radiation gas in the outside world has reached an alarming level. The zombies hiding in the low-lying areas of the city have crawled out in groups, and we have cleaned up Yizheng City twice, but there are still a lot of zombies coming out, and there are a lot of them outside the city wall. ”

Inside the shelter, the message was swift.

Cold spells often occur in Siberia, and every year from September to May, cold waves can occur, and now it is mid-October, and the outbreak of cold waves is not surprising, but it is accompanied by radiation gas, and the impact is too great.

"Meteorological experts believe that the cold wave has changed the pressure balance in the local area, causing the radiation gas riot that accumulates in the low-lying area."

"Radiant gas is very sensitive to temperature and pressure, and it seems that this cold air will not go away, and it will not be dispersed for a while and a half."

"What's more serious is that winter is coming, the temperature is getting lower and lower, I don't know what the impact will be, in case the concentration of radiation gas never goes down, it will be troublesome."

Zhou Yan listened to the discussion of others and frowned.

He is not afraid of radiation gas, the Organism Repair Fleet Lv1 and the Gastrointestinal Material Collection Fleet Lv1 have already reached one billion quantities, which is enough to form a balance with the high concentration of radiation gas, so that Zhou Yan is immune to the harm of radiation gas.

The crowd couldn't help but expect: "I hope it will rain soon and disperse the radiant gas." ”

As if sensing the expectations of these people, at noon, a light rain began to fall. The concentration of radiation in the air dropped significantly and soon fell within the tolerance range of the human body.

The door to the sealed building opened, and someone was ready to walk out.

But the survivor who had just walked out came into contact with the raindrops and suddenly screamed: "Oh! Oh! Hurt! It hurts! ”

"What's going on?"

"These raindrops pierce people!"

"How can raindrops sting!"

"My grass, the skin of my hands is red, what kind of rain is this, acid rain! Hurry up and get me some anti-inflammatory drugs, it hurts me to death! ”

Soon experts studied rainwater and came to the conclusion: "Rainwater is slightly acidic and not corrosive, but it contains an unknown compound that can form a chemical reaction with a certain amino acid in the skin to release heat." It can cause skin damage at least and disfigurement at worst, so everyone should do a good job of preventing rainwater. ”

The poisonous storm has just passed, and the poisonous rain has followed.

This is three days, the entire shelter is trapped in a sealed building for three days, and the occasional team that goes out has to be fully armed and wear clothes similar to chemical protective suits to prevent it from being splashed by the rain.

Zhou Yan took over the task of investigating the outside of the Vault the next day and drove out of the Ninth Vault.

Whether it is a poisonous storm or a poisonous rain, it can't affect him.

……

On the ruins of Yizheng City, zombies were wandering in twos and threes, and when they heard the sound of cars, they immediately rushed towards Zhou Yan, but Zhou Yan had no idea of avoiding them at all.

There were very few people out there, and the off-road vehicles could be picked at will, and he picked a Land Rover. The Land Rover performs well, and the comfort is also high.

The Land Rover has been modified, and the front bumper has been added with a push knife.

The zombies pounced, and they were all cut off by the shovel.

Occasionally, there are evolved zombies, that is, the kind of flying corpses that can run and jump, and before they showed up, Zhou Yan threw out a shot lightly, killing the zombie fifty meters away.

The ear wheel radar group is equipped with a full information tactical ring, and its melee capture and analysis capabilities are invincible.

There is also a Bee reconnaissance aircraft 1.0 flying in the sky, and the situation of the entire city is under his control. It's a wonderful feeling, as if he is the master of the city, and every move cannot escape his eyes.

The stereo played an English song with a familiar melody, but I didn't know what it was singing.

The mobile phone on the frame takes a few photos of the street from time to time, and these photos have to be handed in when they go back.

At this moment, Little Bee found a convoy coming from the east, about five military off-road vehicles, surrounded by thousands of zombies, including hundreds of flying corpses. The convoy's firepower net killed many zombies, but in the face of more and more zombies, they were finally surrounded and could not be freed.

Seeing this situation, Zhou Yan couldn't help but come to the rescue.

However, rushing in front of thousands of zombies is not a good way.

As he rushed to the scene of the incident, he thought of a way to produce a new piece of equipment.

- "The data is being copied, and it has been transmitted to the micron robot in the right-hand processing plant, and at present, Zhou Yan has 2 tons of Baibian ore in storage, which can produce a wristband hook gun system, which is expected to take 3 minutes and 47 seconds, please leave enough space for the right hand to produce...... In production, the remaining time is 3 minutes and 41 seconds......"

Wristband hook gun system, in Zhou Yan's guess, this is similar to the tool used by ancient flower thieves to climb walls.

Dealing with zombies and flying on the wall at a high place is obviously the right way. Four minutes later, the wristband hook gun system was produced, and the shape was a pair of finger-wide silver-black bracers, which were very unpretentious and unpretentious, and there was no high-tech texture to see, and the front was slightly thicker, equivalent to the thickness of an ultra-thin mobile phone.

Gaze gaze.

The data is displayed in the right eyeball.

- "Activation method: Gene fit unlocks. ”

- "System mass: 225 grams. ”

- "Width: 58.1 mm. ”

- "Thickness: 1.34 mm for wrist straps, 2.76 mm for hook guns." ”

- "Energy supply method: heat transfer. ”

- "Operation method: Connect [Left Eyeball Retina Group Lv1]. ”

- "Fixed Position: Connect to [Ear Wheel Radar Fleet Lv1]. ”

- "Method selection: automatic adsorption, hooking, puncture, binding. ”

Attach the wristband hook gun system to your wrist and close the slit as if it were a whole.

- "Detected that there is no energy supply to the wristband hook gun system ring, is there continuous heat to open the operation?" ”

Stop a short distance from the location of the incident, walk down, and turn on the system.

With two fleets, how to use it is very clear, raise your wrist and stretch it out towards a tall building. Suddenly, the front of the system, the hook gun, suddenly bulged two thin tubes, and then two flying arrows shot into the wall of the building, dragging two barely visible silk threads behind them.

Zhou Yan's mind manipulated the reeling line, and the whole person suddenly seemed to fly, dragged by the silk thread and rushed towards the building.

"Spider-Man?"

He inexplicably remembered a movie he had watched.

Then before the whole person had time to react, he hit the wall and hit it, and he was smashed, and his face hurt and his nose hurt.

Although the wristband hook gun system is good, it doesn't have a certain operating technique, and it really can't be played.
