Yu Wen Shi and others were a little confused, but they did not stop Fang Jun from training. After all, Fang Jun had said before that this might be a heavenly soldier.

After finishing the matter of the vanguards, Fang Jun had to work on one big thing, which was to use the resources of the Gewu Department to make the three-spinned spinning wheel and hydraulic spinning wheel.

This thing is a bit difficult. Fang Jun is an amateur, but now he has a hand-rotten spinning wheel. You only need to hire a few craftsmen to copy and make a few pedal spinning wheels and hydraulic spinning wheels.

In addition, cotton is also needed.

Fang Jun already has cotton seeds, and now it can be planted. Fang Jun bought a large bag, enough to plant dozens of acres.

As long as cotton can be made, you will have cotton coats to wear in the future.

As for spinning wheels, it is naturally to create cloth with tighter stitches.

Because it is a bit difficult, Fang Jun needs to spend a lot of time thinking about it.

Fortunately, he doesn't have much work now, so he just needs to go to the vanguards occasionally to check it out, and he can stay at home to study at other times.

Craftsmen naturally found it easy to find them, and they immediately attracted a few people. As for the weaver girl weaving, there are also them.

There were many maids in the palace. Jinyang had a little contact and soon found a few.

"You need to use running water to drive it, or step on it with your feet! This will be faster and the woven fabric will be the best!"

"I don't know what to do. But I probably know the principle, so you can try it as I said! If it doesn't work, let's push it back!"

"Weaving is nothing more than these steps!"

Nowadays, the quality of the cloth in the Tang Dynasty is a bit low and it is easy to crack, which also makes it very unsuitable for use as a hot air balloon.

If you want to improve the quality of the cloth, you can only use tighter stitches and better quality cloth. You must add wool, cotton, linen and silk. This will make the effect better and will be airtight.

There are not many people in the Gewu Department at present. Fang Jun and Li Zhi only summoned three craftsmen in, including Lu craftsmen who made wine.

Nowadays, you need to start from scratch.

"Did you think of spinning wheels from the beginning? This... seems difficult!" Jinyang asked curiously as he looked at Fang Jun busy.

Fang Jun shook his head: "It's not difficult to make. It's not difficult at the beginning, but it's naturally much harder! I'm not afraid to tell you that if this thing is made and promoted, then everyone in the world will probably have clothes to wear in the future! In the future, you may not need to use your hands to weave cloth!"

"Ah?" the little girl immediately exclaimed.

Fang Jun looked at her and couldn't help but be happy, and smiled and said, "What? This is hydraulic power? In addition, foot pedals can also be used, which can definitely be faster than hand pushing. What craftsmen are doing now is to make better cloth! Not only better, but also more quantity than before. If one person could weave half a piece a day, then one person would weave one piece a day now!"

"Then, will the price of cloth drop a lot in the future?" Jinyang said to him with a wide eyelid.

Fang Jun smiled and said, "Of course! It's just that you have to take it out for people to use after making it! At that time, a weaving workshop can be set up in Mingdatang, which specializes in selling cloths! I think Mingdatang sells everything now, a bit like a grocery store. What do you think?"

When Jinyang heard him say this, he felt sweet in his heart and couldn't help laughing and crying: "It's really like a grocery store!"

The reason why she felt sweet was because the name Mingdatang was chosen by her husband.

At the beginning, it was just to sell Luohan Fruit better.

And now, Chang'an is well known.

Although the pedal spinning wheel is difficult to make, just push the spinning wheel and then ask several craftsmen to think about it. Fang Jun reminded him a little of the steps and he still made it quickly.

And he also made a running water spinning wheel.

It's in the river behind the blessed house.

He chose to bring in the river water. When the river water drove the spinning wheel and the gears began to rotate slowly, Jinyang, Xiaohe, Li Zhi and others couldn't help but be amazed.

Needle and thread and linen were quickly taken over and placed on the spinning wheel, and the weaving began soon.

A spinning wheel has an important role, which is to adjust the tightness of the stitches. If you want to do it loose, then do it loose. If you want to do it tight, then do it tight.

Therefore, when the first piece of cloth is made, you must naturally have to knit a cloth with very tight stitches.

When Fang Jun took the cloth and frowned: "This is not enough! It needs to be tighter and tougher! It may be better to add some silk! It's a pity that there is no cotton silk yet!"

"What is cotton silk?" Xiaohe asked in surprise.

Fang Jun glanced at her and smiled and said, "You don't know yet. You will know after a while! This is a kind of cotton produced in the Western Regions. It needs to be planted on the ground and bloom every year. It can keep warm and keep warm, and the effect is better than sable fur!"

"Ah? Then isn't this thing very good?" Xiao He exclaimed.

Fang Jun nodded and smiled, "Of course it's great! I've already planted people. I'm right there on the fiefdom, and I'll probably see it in July and August!"

After hearing what he said, Jinyang, Xiaohe and others couldn't help but feel a little happy.

Fang Jun continued to make someone adjust the weaving cart, intending to make cloth with denser stitches. With the bicycle, it will naturally be easier.

It's easy to produce a piece of cloth again.

Fang Jun took a look and nodded and said, "This looks like it's almost done! But there are still some problems now! That is, how should we get off after going up? We need to set up a mechanism, and the firepower needs to be large and small. If it's large, we can take off. If it's small, we can land."

"How should this be controlled?" Li Zhi asked excitedly.

"It's a bit difficult! But you can give it a try!" Fang Jun smiled and said, "Let's make a smaller one first, and then try it! First, let a sheep fly up!"

"good!"

Everyone was a little excited when they heard Fang Jun say this.

After all, this matter has been said for a long time and has been mentioned a long time ago. Some princes have tried it, but none of them have succeeded. If Fang Jun can do it, it would be of great significance.

The new cloth has been made and it has reached the point where it is airtight. If you want to continue further, you can continue to adjust the density of the pins.

The cloth was stacked five layers, two of which were coated with glutinous rice glue, and the cloth was glued on. After it was done, the head was larger and the tail was smaller.

Tied it with a rope and landed on the ground.

I also made a larger bamboo basket hanging below, where sheep or stones can be placed in the bamboo basket.

Oil, which is made of pine oil, is loaded in a large bottle and hung above a bamboo basket. There is an iron pipe and movable mouth. When igniting pine oil, it can continuously convey hot air.

The difficulty of doing it seems a bit high. Several people stayed in the blessing house for two days before they initially made the first large Kongming lantern.

After it was done, everyone couldn't help but be amazed.

As the tincture oil began to ignite, the steaming hot air began to continuously expand the hot air balloon, and the hot air balloon became larger and rounder.

It gradually appeared above the Blessed House.

When everyone around was surprised when they saw this scene.
Chapter completed!
