Regarding the actions of the president of the Kunming Chamber of Commerce, who prides himself on being his opponent, Zhang Sixing does not know and disdains to know.

After he mobilized the soldiers who could not train for military training because of lack of food, all the construction began to speed up immediately.

Over the Scholar's Castle, groups of three balloons soared into the air. It was nothing more than silk and linen, and the price was really not high compared to the wealth of destruction that was dropped by a bomb.

In addition, each anti-aircraft generator can provide 15 kilowatts of electricity, which will also play a considerable role in promoting the factory area under construction at the moment.

The most basic thing is that under these anti-aircraft generator balloons that can be collected at any time, self-inflating gas lamps for lighting can be installed, turning the construction site into daylight, 24-hour non-stop construction.

The construction workers included not only ordinary people from Jurong, but also soldiers who could not carry out high-intensity military training without military rations, and soldiers who were disabled and could only join the construction.

The first thing that amazed everyone was that the road that emerged from the paratrooper school was developing towards Kunming City at a very fast speed. In order to test the engine he designed, Tang Zhongming has been staying on the road construction site.

Seriously, he'd never seen a road built like this.

Bulldozers with charcoal stoves roared and pushed the ground on both sides of the road. Piled in the middle of the road, and then the rollers come to the field. The five-metre-long rollers are held together in groups of four by a sturdy frame.

Above is a huge carriage with dozens of tons of charcoal pellets and charcoal substitute stoves. They are piped together with FRP gas tanks, into which the cooled, filtered carbon monoxide gas is continuously replenished.

A tractor with four gas engines was installed, the speed was comparable to that on foot. It made an earth-shattering "rumble" and dragged the heavy barrel behind it.

As the roller moved slowly, the road that had been above the ground was crushed in a blink of an eye. But Tang Zhongming knew that such a road could not withstand the wind and rain. Because there is no "aggregate" such as stone, sand or even cinder, its load-bearing capacity should be limited.

However, at this time, the vehicles behind directly transported the "road surface". It was the kind of plywood used to build the castle, and when I heard that there was electricity, the first to start work were the glass silk factory and the textile factory.

There's nothing special about it, it's just sand to be exact. But who plays with sand so clearly in Huaxia, Tang Zhongming estimates that it is only Zhang Sixing.

It is said that when the glass silk cloth could be mass-produced at the plate factory, all the linen cloth and silk were eliminated. Although their physical properties are good, they are still too expensive compared to cheap materials such as glass filament.

At present, these so-called plates are the combination of plywood and glass filament, which is light and strong.

Despite being only five centimeters thick, its strength is comparable to that of steel. Between the two layers of plywood, with a lattice with a side length of 500 millimeters, and finally four thick and long wooden nails are driven through the four corners, forming a pavement five meters wide and five meters long.

Tang Zhongming can see the benefits of such construction. It is not necessarily stronger and cheaper than ordinary roads, and the only advantage is that it can be produced quickly and laid quickly. And as long as there is wood in the mountains and sand can be dug up, then there will be no shortage of raw materials.

As long as there is no shortage of raw materials, then a large number of such plates can be produced quickly, and I don't know how to do other things, but the paving is really enough.

The forklifts and rollers in front are constantly pressing out the solid ground, and the horse-drawn carts coming from the road are constantly followed behind, and the composite panels are unloaded from them, and people are constantly laying on the ground.

It's almost the same as building a scholar's castle, and the speed of construction is too fast.

With the anti-aircraft generators that rise from time to time in the sky, there is an inexhaustible source of energy and light. The road builders have been pushing the road into the distance.

If it was just the speed of road paving that surprised Tang Zhongming, it would be okay, the gas engine, as the most demanded product of Zhang Sixing at this stage, directly adopted the means of verification, modification, and mass production.

This side has only been used on the steamroller, and over there has already sent an airship into the sky.

It is said to be an airship, but in fact it is just a fiberglass skin, and inside are a number of hydrogen balloons that are joked as "air lifebuoys". The latter is being produced as the most demanded air-proof balloon generator.

It is different from the world-famous airship in that it is a two-hull airship, connected by a large movable cabin in the middle, and the principle is no different from the world's famous airship.

Its dual-hull design allows it to do without a vertical tail, and relies on the different forces of the propellers on both sides to achieve this when turning. In the middle, the connecting cabin has a ducted propeller with a diameter of five meters.

They are driven by a gas engine, which directly provides additional lift to the airship. As a result, the load of this twin-hull airship has been increased to five tons, in addition to the lift provided by hydrogen.

It is only one-third the length of the Hindenburg airship, that is, more than seventy meters. The flat body produces more lift when flying forward, which increases its lift even further.

If it is taxied and taken off on a runway like an airport, then its maximum load will rise to seven tons.

Most importantly, this airship is simple to build. Its fiberglass shell maintains its shape, and the "swimming ring" shaped air-proof balloon inside directly becomes the best support.

Of course, such airships can't fly too high, and Zhang Sixing doesn't need them to fly too high. As long as they can transport supplies from all over the country in batches from the air, the work will be completed.

It has a ceiling of 1,000 meters, a speed of 85 kilometers per hour, and a maximum load of 7 tons.

For the time being, for the government that does not have air transport power, this type of airship that can be produced by itself will become the most important air power of the government.

Of course, they can't see this if they are only good at scheming, and Zhang Sixing doesn't know.

Just as the airship he urged lifted off, a gas engine for General Dynamics had also begun mass production. It can be used not only on ships, but also on cars and airships.

As the first gas engine, Zhang Sixing does not expect how much power it can generate, but only that it is simple and solid enough, which is the best equipment for the current Anti-Japanese War.

Combined with a gas tank made of fiberglass, it can make a car carry a load of three tons for 200 kilometers in a row. If it is not too dirty, then the stroke will be further increased if it is replaced by a charcoal oil substitute stove.

What will appear next is the most needed transportation force in the entire Anti-Japanese War - automobiles.
