"Is it Sag?" A voice came from behind the cover.

Wu Chen's black warrior shape and his robot dog have become the most prominent identity signs. The various remnants who often use radio waves to exchange information know these prominent features of Wu Chen.

"It's me." Wu Chen took off his face and revealed his human appearance.

"Wait!" The messy car bunker was like magical building blocks. After a dazzled look, it showed a passage that enough robot dogs entered. It seemed to be electric.

Several guards wearing homemade armor and holding light and heavy weapons rushed out and moved Wu Chen into the air-raid shelter.

Compared to the museum's air-raid shelter, it is more technological here.

The air raid shelter seems to have been expanded many times, and the scale is much larger than before. Those cylindrical iron houses built with oil pipes such as oil tankers, mixing tanks of cement mixers, and various metal culverts are full of doomsday beauty. In these iron houses, Wu Chen also saw CNC machine tools and forging units. Several skilled workers are controlling the machine tools to drive beautiful rifles for a shiny heavy barrel.

"There are deep water wells, power stations, biogas cellars, plantations, breeding farms, charcoal brick factories and tunnel shield machines behind them." Seeing Wu Chen looking around, the leader of the surviving people who came to greet him said proudly.

"So that's it." No wonder it can use electricity on a large scale.

When crossing an explosion-proof gate, the leader of the survivor looked back and pointed at a building at the entrance and said, "This is the factory area of ​​the old air-raid shelter renovated. Going further inside, we are our new home."

Sure enough, as the explosion-proof gate slowly opened, a wide tunnel immediately appeared in front of Wu Chen. This tunnel, which was as wide as two-way four-lane, was excavated by the residents themselves. Every few meters away, there is a small horizontal tunnel perpendicular to the tunnel. The small tunnel is the settlement of the residents. If the small tunnel is compared to a corridor, the "caves" on both sides are the homes of the residents. Wu Chen has seen it in turn, and the water, electricity and ventilation ducts are complete. It is a comfortable underground shelter.

"As the population continues to increase, we have opened up more and more settlements, and more than 20 years have passed without realizing it." The leader of the remnant sighed.

"The increase in population is a great thing." Wu Chen said right. To increase the population, in addition to being safe enough, you also need to have enough food to feed them. It is very difficult to do this in the end when resources are extremely scarce.

"This is all the credit of the old neighbors. Only in the end of the world did we realize that the Eighteen Elevator was originally hidden and lie down. Whatever we wanted was. Senior technicians, senior electricians, senior bricklayers, fitters, welders, carpenters, plumbers, painters, dust collectors, machine tool workers... All the positions we need can find suitable talents. Everyone works together, and Eighteen Elevator has reached the scale today." The leader of the remnants said right. In the world of survival in the doomsday, these groups of people who may be classified as the bottom of society during peacetime are real scarce talents.

This is the same as the fact that small countries that are overly industrialized cannot continue in the doomsday.

Because cars, mobile phones, and circuit boards cannot be eaten as food.

Then, Wu Chen visited the deep water well, power station, biogas cellar, plantation, breeding farm, charcoal brick factory, and the giant tunnel shield machine set up behind the tunnel.

Wu Chen was very curious about what the thermal power station used. The result was a bit unexpected, it was shale gas. They actually found a gas mine.

So there must be prospectors.

True newb.

As a precious clean energy, natural gas produces water and carbon dioxide after combustion. Shale gas is a natural gas resource that can be mined in shale layers. China's recoverable shale gas reserves rank first in the world, and Chongqing Fuling ranks second in the world.

It doesn’t matter whether it’s first or second, just enough.

Once energy is solved, half of the survival problems are solved.

The power plant provides energy and heat sources, even water. Therefore, lighting and heating are available. High-pressure mercury lamps provide sufficient light to the plantation, heating provides sufficient temperature for the hatching of poultry, collects human excrement to produce biogas and organic fertilizers. There are also cave settlements built by collecting charcoal ash and bricks everywhere and accumulating the surface... Various supporting facilities operate in sequence, and a complete underground survival network was successfully established.

No wonder the Eighteen Ladders have such aura in the end of the world.

However, various talent reserves are the prerequisites for everything.

In that case, what else do they want Sag to do?

After visiting for a while, Wu Chen simply asked directly: "What's wrong with you?"

"Gas station." There is nothing to hide before the great Sag.

"Above the gas station is Jiaochangkou, and the smoke exhaust outlet of the power station is also hidden in the tunnel of Line 2. About half a year ago, a giant lizard came to the swamp of the turntable of Jiaochangkou. It was originally peaceful and had it guarded. Lizardmen and other mutant beasts dared not approach it, so we acquiesced to its existence. However, the smoke outlet often made huge noises and earthquakes recently. The smoke outlet is often flooded with water, and the waste gas cannot be discharged in time..."

"I understand." If the carbon dioxide produced after natural gas burning cannot be discharged in time. As the concentration slowly increases and oxygen is squeezed out, people in the entire underground base will unknowingly die of "chronic hypoxia".

This is a huge threat. The reason why it has not happened yet is that the smoke outlet has not been completely filled with water.

"I'll go and see." Human life is at stake. As Sag, he must do this.

"Thank you, sir!" The leader was so excited that he said: "As long as sir helps us solve this big problem, 18 Tiers will be your most loyal partner!"

"Okay." Wu Chen thought for a while and said, "I need some equipment."

"no problem!"

When Wu Chen walked out of the lounge and returned to the factory area, a large group of senior technicians of all ages had already been busy around the robot dog.

The long-axis version of the pod created by the old blacksmith has been removed. Referring to the figure and size of the dog meat, the new cockpit components are being manufactured on CNC machine tools.

The materials used are actually super high-strength steel for submarines!

The machine guns on both sides were also removed, and all important components were replaced by high-strength alloys, greatly extending the service life.

The biggest difference between the old blacksmiths using local materials and hand-made construction is that the craftsmen of the Eighteen-stairs have achieved CNC. With the help of CNC machine tools and various advanced equipment, they can start with the design drawings and build the creation they want step by step.

As the steel plates were successfully spliced ​​by the welding robot, a streamlined fully enclosed pod immediately appeared in front of Wu Chen. The pod door was pulled down from the side, and the top was completely enclosed, without a viewing window composed of bulletproof glass. Obviously, they replaced the observation of the human eye with a more powerful electronic imaging system. Then there was the integration of various weapon systems. Wu Chen even saw the Red Arrow 8F shoulder-mounted anti-tank missile system and the PF97 93mm single-soldier cloud explosion rocket launcher!

Integrating a large number of weapons in a high-tech pod is the rhythm of 007?

Once the redesigned anti-aircraft machine gun is installed, a powerful combat platform will be born immediately. It is like sitting in a mini submarine. In addition to controlling the electric handle of the anti-aircraft machine gun, there is also a very advanced fighter diffraction screen!

Below the diffraction screen is a display panel composed of LCD screens of tablets and mobile phones of various sizes.

Of course they are touch screens!

The largest 14-inch LCD screen displays a 180° wide-angle real-time video screen in the front. The two 7-inch screens on the left show a 90° real-time video screen at the rear. The touch screen composed of a vertical row of 4-inch screens on the right is the fire control ports for various weapons. There is also a ventilation port at the lower part of the screen close to the legs, and the filter can inside is equipped with a nuclear biochemical-grade air filter element. This is not the coolest. The coolest part is that there is a IWG mechanical watch embedded directly below the diffraction screen!

It feels like it was obviously dug from the center console of a luxury car!

There is a bitch in the center console!

I feel like I'm getting tall immediately...

After soliciting Wu Chen's opinion, the pod on the right was also replaced with the heavy machine gun with the same anti-aircraft machine gun as the left. The large-capacity ammunition box has 1,000 rounds of ammunition.

Having a system means having a chip, and having a chip means being programmable. TT40 quickly reintegrated various video fire control systems that were pieced together randomly, and integrated data with dog meat's radar and Wu Chen's armor, greatly enhancing the function of the pod. Also, because various weapon units realize electric transmission, she quickly controlled the pod on the right.

After replacing ceramic composite reaction armor that is much lighter than the previous metal armor, the weight will exceed 5 tons. One-tenth of the weight is not a problem for dog meat.

Although the heavy alloy itself looks very beautiful, Wu Chen still asked the painter to spray a black anticorrosion coating to cover up the sharpness of the two combat bunkers.

Bring the canned lunch meat and pure water made by the remnants, and the new dog saddle was on his back. The dog meat ran out of the air raid shelter and turned to the gate of the field.

Jiaochangkou is located in the south of the Yuzhong Peninsula in Chongqing and is the most prosperous commercial center in Chongqing. Of course, these air raid shelters are also on the Yuzhong Peninsula.

There was originally a large turntable here, which is the so-called roundabout. Vehicles that intersected around the circle around the circle and turned to the direction they were going in sequence. Like all turntables, there was greenery on it. However, at this time, the roundtables and the ring road were completely invisible, and they had already accumulated a vast swamp by overflowing groundwater. The ruins of buildings soaked in the swamplands were like civilized islands, submerged in the vast ocean of the end of the world.

Compared to the endless charred black around, Wu Chen saw the rare green. The rich aquatic plants and unknown wild flowers decorated the entire swamp with vitality and was filled with rare wild fun.

Of course, if it weren't for the burned buildings that were too unsightly, this was definitely the pearl of the doomsday and the holy place of the soul.

Choosing to build a nest here is obviously a water lizard. (To be continued.)
