In Renault's fleet, there are almost no copper coins. The thing is too heavy and takes up space. Renault is too lazy to bring it, and even has few silver coins. In addition to more than a dozen gold coins, Renault is more willing to reserve resources such as life-saving pills and red ginseng, which can not only be spent as money, but more importantly, it is used for practice.

Since seeing the power of warriors, in Renault's heart, the hot weapons and all-warrior warrior warriors have been in a state of swaying. It was not until the Austrians appeared that gunpowder weapons were taken seriously. Before that, Renault's imagined strong soldiers were a full-warrior warrior.

Earth Immortals are the commander, and the military academy graduates form a general staff department. The master leads all warriors to charge into battle. When he thinks about it, he feels excited.

With the same number of people, the thermal weapons troops holding muskets and using antique-level artillery are definitely not the opponent of the entire warrior warrior troops, and the difference is not a little bit.

Before this, Renault always felt that the troops of thermal weapons, aircraft, hot air balloons, and airships should be used as auxiliary troops and the flight troops as the main force in transportation.

No matter what Renault thought, he had to bring such resources as cloth, and the quantity was not small. Renault had never thought about what to exchange for cloth. Just because of the clothes of his subordinates in the future, it was worth him to bring a lot of cloth for travel.

You should know that Dachu's textile industry is very backward, mainly hemp, with poor quality, and all the tears they say are all about. They are wearing fine linen cloth, and it is considered good to wear it for a year.

The elephant convoy marched day and night. Even if Renault tried his best to take a shower in a few days, he had already tried his best. As people walked more roads, they would naturally sweat a lot. In addition, cutting down trees to open roads, digging soil to cushion the road, and the sun and wind blew, the damage speed of linen clothing would only be faster.

After this year, the subordinates of the Shengong Palace had to consume an average of three to five sets of clothes. This is not counting shoes. It is normal to break a dozen pairs of shoes.

There is not enough cloth, and the Shengong Hall convoy belongs to it. At this moment, I am afraid that I can only use leaves to cover my shame like the Nanzhangtu toast.

Renault gritted his teeth and chose silk as the fabric for hot air balloons. It was not luxury for Renault, and there was no way to do it. The fabrics in Dachu were too bad. It was okay to say that in summer, whether it was hemp or silk, they were very breathable. In winter, even the little nobles would not live a good life.

This is also why in ancient times, the north was ruled by nomadic peoples. It was not that they didn’t want to, but that the conditions were just like this. When the farming people arrived in the north, the problem of keeping warm in winter alone could not be solved, and most people would freeze to death.

Nomads do not have hemp, so no matter when they are, they are all wearing leather jackets. They have enough livestock, so they naturally have no shortage of fur.

Of course, there is also a question of the definition of the north here. Whether it is the ancient earth or the Great Chu world, the north refers to a latitude like Luocheng, where snow in winter, it is the north. As for Liaodong, the place where it can reach minus 2 or 30 degrees in winter can no longer be considered the north, it is called a barren land.

The yarn of hemp and silk is not dense enough. Renault tried it. If it is just one layer, whether it is hemp or silk, it will leak air. It leaks very quickly. At least three layers are needed to be used on hot air balloons. If it is good, it will require five layers.

The silk is better, but the weight of hemp is not light. Not to mention the fifth floor, it only takes three floors. After the calculations of the God of Wealth, the hot air balloon can only barely float. It is good if it can fly for dozens of meters. If it is installed with people and goods, it will not fly at all.

After searching, Renault found that only silk is easy to use. With only two layers of silk, it will not leak much. If it is three layers, the effect will be better.

The most important thing is that silk is lightweight. Even if three layers of silk are similar to one layer of hemp, the only disadvantage is that it is expensive.

Is Renault a shortage of money? What he is considering now is not the question of whether silk is expensive or not, but the limited number of silk in the fleet and the surface area of ​​the hot air balloon is too large and not enough.

This time, only the experimental hot air balloon is only ten meters in diameter. Among the hot air balloons planned by Renault, it can only be regarded as small hot air balloons. Even so, its surface area is more than 300 square meters. If Renault wants to have a better effect, he prepared three layers of silk fabric, which is 900 square meters of silk.

Several carts looked a lot of silk, but they really wanted to be used as hot air balloons. The results of Renault's calculations made him a little disappointed.

After several days of hard work, the black hair and the plane finally delivered everything Renault wanted to the Tianyun Valley. In addition to a large amount of silk, there were needles, threads, dozens of blacksmiths, and a complete set of blacksmith tools.

The hot air balloon stand woven by green bamboo was ready, layer by layer of silk began to cover the surface, and all the skillful hands and wives of Liuyun went on battle together.

The blacksmith made the spray guns, propellers, manpower transmission systems that Renault needed, and the fine rattan made into hanging blue.

The first time I made a hot air balloon, under the command of Renault, a not-so-reliable chief engineer, was naturally stumbling. It took nearly ten days to finally make the manufacturing.

Renault looked up at the twelve-meter-high hot air balloon and was in a good mood. In order to facilitate takeoff and landing, he chose a frame-type hot air balloon, so that he did not need to use a blower to blow hot air. The disadvantages are also that frame-type inconvenient transportation.

On the surface of the hot air balloon, Renault burns people to draw the logo of the Temple of Shengong, with the word "Shengong". Each character is more than five meters high and can be seen clearly from a thousand meters away.

"Ignite." With Renault's order, Song Zhe ignited the flowing balm in the combustion chamber. Two ninth-grade warriors began to suppress the spray gun pressure chamber. Song Zhe waited for a while, reached out to press the spray gun's hand.

A terrifying sound was 'sucking'. Under the influence of air pressure, the flames spewed out more than three feet high, which made Renault feel palpitations. Although the silk was made of an original fireproof layer, it was more than three meters away from the fire spitting mouth. It was silk after all, and this thing was flammable.

Fortunately, what Renault was worried about did not happen. Before the test flight, the fire-breathing heating port had been tested for nearly a hundred times. Even in the strong wind, the flames could not burn silk.

Two ninth-grade warriors kept pressuring, and the flames spewed out heat to heat the air inside the ball. After waiting for a quarter of an hour, the hot air balloon swayed and floated up.

When thousands of people cheered in unison when they saw the hot air balloon floating up, they couldn't figure out how the thing made by Mr. could fly?

In the hot air balloon at this time, in addition to Song Zhe, the test pilot, there were six ninth-grade warriors who cooperated with him, as well as sandbag counterweights weighing nearly tons.
