Early the next morning, the entire Tianyun Valley became extremely busy, and the leisure of the past was gone. Mr. issued a series of orders that no one could understand, and Lan Yunxi could only assign the task to the understaff, so he let Hei Mao rise into the air and pick up some of the people from Jiaojiazhai to respond first.

Hundreds of bamboos were cut down, which made Lan Yunxi feel a little heartbroken, she and Liuyun's people were all playing in the bamboo forest, and the bamboo in Nanzhang was actually not uncommon, but near Tianyun Mountain, there was only this small bamboo forest by the valley lake.

After the bamboo is cut, the knots are polished and the bamboo is split into finger-width strips. Many more were sent to the rainforest to collect balsam.

Flow balsam is a kind of tree oil secreted from the tree called flow incense tree, this kind of tree is many, first cut a small hole in the bark of the tree, prepare a clay pot, hang it on the incision, one day and one night, you can collect a small pot, Mr. wants a large number, Liuyun will almost all the clay pots that can be found, are used to collect flow balsam.

The split bamboo strips, under the command of Renault, began to be tied into a hollow oval bamboo frame, this ten-meter-high bamboo frame is not strong at all, it takes nearly 100 people to work together, and it took a day to tie it.

"Sir, no one was caught. Song Zhe said with a tired face, one day and one night, more than a thousand miles back and forth, and still looking for people, even if it is an earth immortal, it is very hard.

"Ran away?" asked Renault.

It's really gone, that Dong Xuanzi is extremely cunning, and he was originally going to use his own strength to collect all the toasts within a radius of thousands of miles, with his sect master's cultivation, as long as he is attentive, he may be able to really do it if he spends some time.

Within a few days of coming here, he subdued Tong Mancang and sent people to persuade the surrounding Tusi to surrender. A few days ago, Dong Xuanzi received news that the Tianyun Valley, where the biggest enemy Liuyun was located, had a lot of black hair.

Dong Xuanzi originally wanted to go to Tianyun Mountain in person to subdue Liuyun, but when he heard that there were hundreds of black hairs, he was tempted at that time. deceived Tong Mancang, and only said that he would go out to suppress a certain toast, but in fact, he quietly sneaked to the periphery of Tianyun Mountain.

Halfway through, I heard that another batch of black hairs came to Tianyun Mountain, and this batch was more than 300. Before he was halfway down the road, Dong Xuanzi ran away. can control hundreds of black hairs, he really can't think of what kind of power the other party is, anyway, all the big chus together, I'm afraid he can't find so many black hairs.

Feeling that things were not good, Dong Xuanzi was very vigilant, and he didn't check what the other party was about, so he ran away without a trace, and no one knew which direction he was running.

By the time Renault received the message from Song Zhe and mobilized the God of Wealth to find someone, Dong Xuanzi had already flown thousands of miles on a bald eagle.

A grandmaster is obviously not worth Renault's attention, if it weren't for Dong Xuanzi from the Hanging Temple, Renault would not have mobilized the God of Wealth to scan him at all, and now Renault's vision is also high, an ordinary grandmaster, where would he put it in his eyes.

Run, run, find the asbestos and green bamboo in Tianyun Valley, where does Renault have the heart to care about the Hanging Temple?

In the next few days, not only were thousands of black hairs so tired that they were about to vomit blood, but even the convoy slowed down their march, starting early every day, camping in the afternoon, driving out of an open field, and all the planes did the work of transport planes.

In the Great Chu world, in addition to copper, silver, and gold can be used as money, there is another material that can also be directly used as money, and that is cloth. The so-called cloth here refers to a general term, including silk, silk, and linen, and everything that can be worn can be directly spent as money, and even part of the salary of officials is paid with cloth.

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

Since seeing the strength of the warriors, in Renault's heart, the hot weapons and the all-martial warriors have been in a state of swaying, until the appearance of the Otto, gunpowder weapons have been taken seriously, before that, the strong soldiers in Renault's imagination are a warriors of the all-warriors.

The earth immortal is the commander, the graduates of the military academy form a staff department, and the grandmaster leads the whole warrior soldiers to charge into battle, and I feel my blood boiling when I think about it.

With the same number of people, the thermal weapons unit with muskets and antique-grade artillery is definitely not the opponent of the all-martial arts combat unit, and it is not a little bit worse.

Prior to this, Renault had always felt that whether it was thermal weapons, aircraft, hot air balloons, airships, or other troops, they should be used as auxiliary arms, and flying units should be used as the main force for transportation.

No matter what Renault thinks in his heart, cloth is a resource that must be brought, and the quantity cannot be less, Renault has not thought about exchanging cloth for anything, just the clothing problem of his subordinates in the future, it is worth him to bring a lot of cloth to travel.

You must know that the textile industry in Dachu is very backward, mainly hemp, the quality is too poor, it is full of tears, and it is good to wear it for a year in a fine linen clothes.

Like a convoy marching, day and night, even if Renault tried his best, he could take a shower once in a few days. People walk a lot of roads, naturally sweat a lot, plus cut down trees to open the way, digging soil mats, sun and wind, the damage of linen clothes will only be faster.

This year, the subordinates of the Shengong Hall have to consume an average of three to five sets of clothes, not counting the shoes, it is too normal to break more than a dozen pairs of shoes.

There is not enough cloth, and the convoy of the Shengong Hall belongs, so I am afraid that at this time, I can only cover my shame with leaves like Nanzhang Toast.

Renault gritted his teeth and chose silk as the fabric for the hot air balloon, which was not a luxury for Renault, but there was really no way. Da Chu's fabric is too poor, it's good to say in summer, whether it's hemp or silk, it's very breathable, and in winter, even the little nobles don't have a good time.

This is also why in ancient times, the north has been ruled by nomads, not because they don't want to, but because the conditions are like this, when the farming people go to the north, the problem of keeping warm in winter alone cannot be solved, and the vast majority of people will freeze to death.

The nomads don't have hemp, so no matter what time it is, they are all dressed in leather, and they have enough livestock, so they naturally don't lack fur.

Of course, there is also the problem of the definition of the north, whether it is the ancient world on the earth, or the world of Great Chu, the north refers to a latitude like Los Angeles, and the winter sun and snow fall, that is the northland. As for Liaodong, the kind of place that can reach minus 20 or 30 degrees in winter can no longer be regarded as the north, it is called barren land.

The yarn weaving of hemp and silk is not dense enough, Renault has tried, if it is just one layer, whether it is hemp or silk, it will leak air, leak quickly, at least three layers or more, in order to be used on the hot air balloon, if you want to have a good effect, then you need five layers.

The silk is better, the weight of hemp is not light, not to mention five layers, as long as three layers, after the calculation of the God of Wealth, the hot air balloon can only barely float up, it is good to be able to fly dozens of meters, and then load people and goods, it can't fly at all.

Looking around, Renault found that only silk is easy to use, as long as there are two layers of silk, there is not much air leakage, if it is three layers, the effect will be better.

The most important thing is that the weight of silk is light, even if it is three layers of silk, the weight is similar to that of one layer of hemp, and the only disadvantage is that it is expensive.

Is Renault a man who is short of money? What he is thinking about now is not whether silk is expensive, but the limited amount of silk in the fleet, and the surface area of the hot air balloon is too large to be used.

This time it was only an experimental hot air balloon, with a diameter of only ten meters, which can only be regarded as a small hot air balloon in the Renault program, and even so, its surface area is more than 300 square meters. Renault wanted to have a better effect, and prepared three layers of silk fabric, which was 900 square meters of silk.

Several pack carts of silk looked like a lot, but they really had to be used as hot air balloons, and the results of Renault's calculations made him a little broken.

After several days of hard work, Hei Mao and the plane finally sent all the things that Renault wanted to 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 rack woven by green bamboo has long been prepared, layers of silk have begun to cover the surface, and all the skillful daughters-in-law of Liuyun have gone into battle together.

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

The first time a hot air balloon was made, and under the command of Renault, an unreliable chief engineer, it was naturally stumbling, and it took nearly ten days to finally complete the manufacture.

Renault looked up at the twelve-meter-high hot air balloon, in a good mood, in order to facilitate take-off and landing, he chose a frame-type hot air balloon, so that there is no need to use a blower to blow hot air, there are also shortcomings, the frame type is inconvenient to transport.

On the surface of the hot air balloon, the Renault baked bag made people draw the logo of the Shengong Temple, the word 'Shengong', each word is more than five meters high, and it can be seen clearly from a distance of thousands of meters.

"Ignition. Renault gave an order, Song Zhe lit the flowing balsam in the combustion chamber, and the two Jiupin martial artists began to suppress the spray gun pressurization chamber, Song Zhe waited for a moment, reached out and pressed it on the wrench of the spray gun.

'Zi' a terrifying sound, under the action of air pressure, the flame erupted more than three feet high, making Renault's heart palpitate, although the silk was made of a primitive fireproof layer, close to the location of the flamevent, using more than three meters of asbestos cloth, but after all, it is silk, this thing is flammable.

Fortunately, what Renault feared did not happen, and before the test flight, the flame-breathing heating port had been tested nearly 100 times, and even in strong winds, the flame could not burn the silk.

The two Nine Rank Martial Artists kept pressurizing, and the flames spewed heat, heating the air in the sphere, and after waiting for a quarter of an hour, the hot air balloon staggered and floated.

Seeing the hot air balloon floating, thousands of people cheered in unison, and they couldn't understand until this moment, how could this thing made by Mr. fly?

In the hot air balloon at this time, in addition to Song Zhe, the test pilot, there were six nine-rank martial artists who cooperated with him, as well as nearly a ton of sandbag counterweights.

Under the hanging blue, fixed with thick vines as thick as eight children's arms, the hot air balloon will not float away although it is rising.
