Doomsday: Humanity shrinks 100 times

Chapter 198 Scaffolding

Lu Yuning said: "But the key here is the communication problem."

This is easy to understand. During actual combat, the hot air balloon should be at least three meters above the ground, otherwise its own safety will be difficult to guarantee.

Therefore, it is difficult to achieve rapid communication in land-air coordination.

The key person here is definitely Zhang Xinyue.

Zhang Xinyue will be responsible for reconnaissance work in the hot air balloon.

"So communication is one-way. To achieve coordinated action, air capabilities must be coordinated with ground operations, so the ground team must have a reliable commander."

Lu Yuning organized his thoughts and spoke.

When he said this, the candidate had actually been basically determined. As a veteran, Chen Hong was the most suitable person for this command position.

If it is a small team battle, Lu Yuning can do it, but when it comes to marching and fighting, Chen Hong is the professional.

"Brother Chen's ability also guarantees the safety of the ground forces. He can be said to be the most suitable candidate."

Chen Hong was also in the conference room at this time. Seeing Lu Yuning's gaze, he scratched his head and said, "Okay, although I would rather use my superpowers to kill everyone..."

Lu Yuning smiled and said, "You can use this mobile fortress as your mobile shelter."

Chen Hong's eyes lit up. "That makes sense. This thing needs someone to push it anyway. My abilities are just right for this. I can push the armored fortress while observing and directing!"

Lu Yuning nodded and finally said, "Let's just leave it as it is for now. There's no point in going into a lot of details. We need to get the product done first."

Finally, after summarizing the current matters, Lu Yuning ended the meeting.

The production of the hot air balloon officially began.

The principle of a hot air balloon actually relies on the buoyancy of the air. The reason for the buoyancy is that the air inside the balloon expands when heated, resulting in a density difference between the inside and the outside.

When the buoyancy exceeds the weight of the hot air balloon, it will naturally rise.

Therefore, the material of the hot air balloon is very important. The requirement is that the density must be low, and another point is that it must be flame retardant.

Hot air balloons are usually made by adding flame retardant to the top of the balloon.

This is actually the difficulty in their production.

Obviously they don't have flame retardants, so they must have suitable materials.

The only thing that comes to mind is metal products, but if metal is added, the hot air balloon itself will be overweight.

So this is the key to Li Wengang's supernatural power.

Without him, this would be difficult to achieve with their current materials and capabilities.

As for the materials for the hot air balloon, Lu Yuning discussed it with Zhang Muyan and Zhang Xinyue.

The main balloon part is normally made of paper, which is also the material used to make Kongming lanterns.

But they don't have much paper to use now, so they have to use plastic instead.

The main body of the balloon should be made of lightweight wooden material as the lamp frame, and then plastic film should be used as the lampshade.

You can first try to use aluminum as the heat source. If it can, the steps will be much simpler and it will have some windproof ability.

Finally, add a layer of aluminum foil where the balloon will be heated the most.

The basket below is relatively simple, just choose some light material. Finally, the weight of the hot air balloon as a whole is reduced to reach the weight that can take off.

This hot air balloon is quite large, and Lu Yuning cannot make it directly with his ability. Moreover, some parts of the balloon are made of different materials, and even if he has enough ability, he cannot directly fuse and reassemble the two materials.

The materials need to be processed and then a way to assemble them together is needed, so an engineering scaffolding needs to be built first.

According to the design, the volume of the entire hot air balloon is at least 40cm x 20cm.

What does this mean? It is almost 20 times the current human height.

It is almost as high as a 10-story building from a normal perspective, so you can imagine how difficult the project was.

The scaffolding used for construction is even larger, so Lu Yuning cannot make it all in one go.

For this part of the work, he had to process the materials and then build it through manpower, and the main force of the construction was the abilities of Chen Hong and Li Wengang.

Fortunately, they now have a lot of people. Although the productivity that non-superpowers can produce is limited, it can still be of great help if someone can handle the materials for them.

The importance of Li Wengang's abilities gradually became apparent. Whether it was the operation of some equipment or the weight reduction of materials, he was required to handle it.

The only regret is that his ability is not a continuous state change.

I can't maintain a certain state for a long time like Zhang Muyan or Zhang Qian.

Therefore, in many cases, Li Wengang still needs to do it himself, which is quite a pity, so Li Wengang also became a big shot in base construction.

The branch basically stopped its current work and fully participated in the construction of the hot air balloon.

The construction site was located near the branch, mainly because the branch already had stable night lighting.

The last time Lu Yuning handed the small motor to the branch for processing, they actually lit up the small light bulb.

This surprised Lu Yuning greatly. It was just a casual decision at the time, but he didn't expect that it could actually generate electricity.

Although the electricity currently generated can only support the lighting of a small low-power LED lamp, it is already quite important for them.

Although they could also use pine oil lamps to provide lighting, pine oil was not easy to make and consumed in large quantities.

Many of their weapons rely on pine oil, so it would be a waste to use it for lighting.

With this true night lighting, they finally bid farewell to the pain point of being unable to work at night.

However, this simple small-scale power generation system must rely on the water energy of the tributary, which is driven by the water wheel and the gear ratio to amplify the speed, thereby generating reverse electricity through the motor.

Although Lu Yuning really wanted to move this system back, it was really unacceptable.

Moreover, it is not easy to manufacture this waterwheel. The main reason why the branch can be successfully built is that the location of the tributary is more suitable for construction.

If you want to build a waterwheel like this on the main river next to the headquarters, the difficulty will be incomparable.

So after comprehensive consideration, Lu Yuning decided to temporarily place this facility here. After all, the people in the branch also put a lot of thought into it.

It may be possible to disassemble this motor and use the materials inside to make some small generators in the future. The principle of power generation is the same anyway, and Lu Yuning can now control metal, so it can be placed on future vehicles.

In short, the scaffolding of the hot air balloon is placed at the branch, and the people in the branch are also the main force of the construction. This group of people now cooperates quite well, and everyone's work enthusiasm is still relatively high. After all, it is a very fulfilling thing to be able to personally participate in the construction of such a cross-century facility.

It will take some time to build the scaffolding, so it can be temporarily handed over to the branch for construction. Lu Yuning will take the time to prepare to make cold-resistant clothes for the branch.

After all, we can't let everyone work at night in the cold wind. The temperature is already very low at night, and catching a cold is a very troublesome thing.
