"On the other side, Sag?" Voices came from behind cover.

Wu Chen's black warrior shape and his robot dog have become the most prominent identity symbols. The various remnant sites that often exchange information with each other on the radio waves know these remarkable characteristics of Wu Chen.

"It's me." Wu Chen peeled off his face armor, revealing his human face.

"Wait a minute!" The messy car bunkers were like magical building blocks, and after a dazzling movement with each other, they revealed a passage large enough for the robot dog to enter. It still seems to be electric.

Several guards wearing homemade armor and holding light and heavy weapons hurriedly rushed out and welcomed Wu Chen into the bomb shelter.

Compared to the museum bomb shelter, this place is a little more technological.

The bomb shelter appears to have been expanded several times and is much larger than before. The cylindrical tin houses built with tubing such as oil tankers, mixing tanks for cement mixer trucks, and various metal culverts are full of apocalyptic beauty. In these iron houses, Wu Chen also saw CNC machine tools and forging units. A handful of skilled workers are controlling the machine to create a graceful rifling of a shiny heavy barrel.

"Behind it are deepwater wells, power stations, biogas cellars, plantations, livestock farms, charcoal ash brick factories and tunnel boring machines." Seeing Wu Chen looking around, the leader of the remnants who rushed to greet him said with pride on his face.

"I see." It's no wonder that electricity can be used on a large scale.

As he crossed a blast gate, the leader of the remnants looked back and pointed to a building at the entrance and said, "This is the factory area of the old bomb shelter, and further inside, there is our new home." ”

Sure enough, as the explosion-proof gate slowly opened, a wide tunnel immediately appeared in front of Wu Chen. This is a two-way, four-lane wide tunnel. It was completely excavated by the remnants themselves. every few meters apart. There is a small transverse tunnel perpendicular to the tunnel. Inside the small tunnel is the settlement of the remnants. If you compare a small tunnel to a corridor. The 'caves' on both sides are the homes of the remnants. Wu Chen looked at it in turn, and the water, electricity, and ventilation pipes were complete. It's a comfortable underground shelter.

"As the population continues to increase, we have opened up more and more settlements, and before we know it, more than 20 years have passed." The leader of the remnants sighed.

"Population growth is a great thing." Wu Chen was right. If you want the population to increase, in addition to being safe enough, you need to have enough food to feed them. In the last days when resources are extremely scarce, it is not easy to do this.

"It's all thanks to the old neighbors. to the end times. Only then did we know that the eighteen ladders were originally hidden dragons and crouching tigers, and what they wanted. Senior Mechanic, Senior Electrician, Senior Bricklayer, Fitter, Wolder, Carpenter, Plumber, Painter, Duster, Machine Tool Worker...... We can find the right people for all the positions we need. The big guys worked together, and the eighteen ladders have today's scale. "The leader of the remnants is right. In the apocalyptic survival world, these peacetime people may be classified as a group of people at the bottom of society, but they are really scarce talents.

This is the same reason that those small, over-industrialized countries cannot survive the end of the world.

Because cars, mobile phones, and circuit boards can't be eaten.

Later, Wu Chen visited the deep-water wells, power stations, biogas cellars, plantations, breeding farms, charcoal ash brick factories and the giant tunnel boring machine set up at the back of the tunnel.

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

So there must be prospectors too.

REALLY NEWB.

Natural gas is a precious clean energy source that is burned to produce water and carbon dioxide. Shale gas is a natural gas resource that is deposited in shale formations and can be exploited. China's recoverable shale gas reserves rank first in the world. Chongqing's Fuling shale gas reserves rank second in the world.

It doesn't matter if you're the first or the second, it's enough.

Energy solved. Half of the survival problems are solved.

Power plants provide energy and heat sources, and even water. So there was lighting and heating. High-pressure mercury lamps provide sufficient light for plantations, heating provides sufficient temperature for poultry hatching, human waste is collected to produce biogas and organic fertilizer, and cave settlements are built by collecting ubiquitous charcoal ash and bricks that fill the ground...... All kinds of supporting facilities are operated in turn, and a complete underground survival network is successfully established.

No wonder the Eighteen Ladders can have such a weather in the last days.

However, all kinds of talent reserves are the premise of everything.

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

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

"Gas station." In front of the great Sag, there is nothing to hide.

"The gas station is above the main entrance, and the smoke exhaust of the power station is also hidden in the tunnel of Line 2. About half a year ago, a monitor lizard came to the swamp of the turntable at the entrance of the field. Originally, it was safe with us, and with it guarded, the lizardmen and other mutant beasts did not dare to approach, so we acquiesced to its existence. Recently, however, there has been a lot of noise at the entrance of the field, which is accompanied by earthquakes, and the smoke exhaust is often flooded with stagnant water, and the exhaust gas cannot be discharged in time......"

"Understood." If the carbon dioxide produced by the combustion of natural gas cannot be discharged in time, as the concentration slowly increases, the oxygen is squeezed out, and the entire underground base will unknowingly die of 'chronic lack of oxygen'.

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

"I'll take a look." Human lives matter. As Sag, he had to do it.

"Thank you, sir!" The leader's excitement was overflowing: "As long as the adults help us solve this big trouble, the Eighteen Ladders will be your most loyal partner!" ”

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

"No problem!"

Wait for Wu Chen to walk out of the lounge and return to the factory area. A large group of senior technicians of all ages have long been busy around the robot dog.

The long-axis pod made by the old blacksmith has been removed. Referencing the body shape and size of the dogmeat, the new cockpit components are being manufactured on CNC machines.

The material used turned out to be ultra-high-strength steel for submarines!

The machine guns on both sides were also removed, and all important parts were replaced with high-strength alloys, which greatly extended the service life.

The biggest difference with the old blacksmith who took local materials and built them by hand is that the craftsmen of the eighteen ladders have achieved numerical control. With the help of CNC machines and a variety of advanced equipment, they are able to start from the design drawings and build the creations 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 is pulled down from the side, and the top is fully closed, and there is no observation window composed of bulletproof glass. Apparently, they replaced the observation of the human eye with a much more powerful electronic imaging system. Then there is the integration of various weapon systems. Wu Chen even saw the Red Arrow 8F shoulder-mounted anti-tank missile system and the PF97 93mm individual cloud burst bazooka!

Integrating a large number of weapons into a high-tech pod, this is simply the rhythm of 007, okay!

When the redesigned anti-aircraft machine gun was loaded, a powerful combat platform was born. It's like getting into a mini-submarine. In addition to the control of the electric handle of the anti-aircraft machine gun, there is also a very advanced fighter diffraction screen on the control panel!

Underneath the diffraction screen is a display panel made up of LCD screens of tablets and mobile phones of various sizes.

They're touchscreens, of course!

The largest 14-inch LCD screen displays a 180° wide-angle real-time video screen in front, two 7-inch screens on the left display a 90° real-time screen in the rear, and a 4-inch small screen on the right is a fire control port for various weapons. There are also vents in the lower part of the screen near the legs, and the filters inside are fitted with nuclear, biological, and chemical grade air filters. This is not the most stylish, the most popular thing is that there is an IWC mechanical watch embedded directly below the diffraction screen!

It feels like it's obvious that it was dug from the center console of a luxury car!

There's a in the center console!

I feel like I'm tall right away......

Wu Chen's opinion was consulted, and the right pod was the same as the left, replacing the heavy machine gun with the same anti-aircraft machine gun. Large-capacity ammunition box with 1,000 rounds of ammunition.

TT40 quickly reintegrated the various video fire control systems that were patched together, and integrated data with the radar of dog meat and Wu Chen's armor, which greatly strengthened the function of the pod. Also because the various weapon units were electrically transmitted, she quickly took control of the right pod.

When replaced with a ceramic composite reactive 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 at all.

Although the color of the heavy alloy itself is very beautiful, Wu Chen still asked the painter to spray it with a black anti-corrosion coating. Cover up the edges of the two battle bunkers.

Bringing the remnants' homemade canned luncheon meat and purified water, and carrying a brand-new dog saddle, the dog meat ran out of the bomb shelter and turned to the entrance of the field.

Located in the southern part of the Yuzhong Peninsula in Chongqing, Jiaochangkou is the most prosperous commercial center in Chongqing. Of course, these air-raid shelters are also on the Yuzhong Peninsula.

Originally, there was a large turntable, the so-called roundabout. Vehicles traveling to and from the intersection make a detour around the roundabout and turn in turn in their respective directions. As with all turntables, there is greenery built into it. However, at this time, the roundabout and the ring road were completely invisible, and the overflowing groundwater had already accumulated into a vast area of marshland. The ruins of buildings soaked in the swamp are like islands of civilization, submerged in the ocean of the end times.

Compared to the endless scorched black around him, Wu Chen saw a rare green. Abundant aquatic plants and unknown wildflowers decorate the entire swamp with life, full of rare wild fun.

Of course, if it weren't for the burning buildings, this would definitely be the pearl of the apocalypse and the holy place of the soul.

Choosing to nest here, apparently a water lizard. (To be continued......)
