Li Natural and Shen Wanbao lost tens of thousands of taels of silver in the Flying Rockets project, and a bunch of Flying Rockets could not be sold. They were in a state of grief and cried and called for their parents.

Suddenly, when they heard Xiang Tiange say that Xiaohunhou had a way to save them, the two of them turned sad to joy and immediately went to Chu Tianxiu to ask for advice.

Chu Tianxiu gave them a trick.

He is now fully committed to developing gunpowder guns and heavy artillery, which are two super-large military weapon projects. He has no time to do those small research, so he just lets them do it.

"This gunpowder has a wide range of uses, both military and civilians can be used.

For civilian use, you can make matches, fireworks, and firecrackers. Matches are used to ignite fire on the stove, which is much more convenient than flint.

Fireworks are miniature rockets that can fly into the sky and explode. The sky is full of fire, which is very beautiful.

The people have a huge demand for these two things. Don’t be too expensive. Sell a few copper coins, which will make small profits and sell them to the entire Dachu. You can make a lot of money in a year.

Old Shenxian Li had no way to the court, so he took civilian gunpowder to invent it.

In military use, rockets can be developed. They are not large flying rockets that can sit on people, but small rockets like arrows. The technology is low and the more useful it is. The farther you shoot, the better! It is best to be able to explode and kill enemies.

Shen Wanbao has a close relationship with the royal family and can develop such arms.

Moreover, fireworks, firecrackers and rocket gunpowder technologies are the same, but the materials used to make rockets are different. You can work together to develop technology and share technology."

Chu Tianxiu had a few little ideas.

Selling matches is a necessity for civil use. This one alone can earn a lot of copper coins. Mass production, one or two copper plates, is definitely willing to spend money.

Fireworks, firecrackers, small rockets.

It's similar to the principle of the Flying Rockets.

The Feixian Rocket, which is so high-end, is ridiculously expensive... If you take too big steps, you will definitely get rid of the eggs.

It's still easy to sell the Rockets.

Fireworks are used to appreciate, and they are even more popular during festivals and the sales are definitely good.

"The fireworks are for viewing?!"

"Xiao Hunhou, I just want to buy it to watch the fireworks explode in the sky?... Why does it sound like it seems very unreliable!"

Li Natural and Shen Wanbao were a little confused when they heard this.

Just to see and hear a sound, which fool is willing to spend money?

Fireworks sounds even more unreliable than their Flying Rocket project.

It would be more interesting to sit on a flying rocket and fly into the sky yourself.

At least, I went up and sat down and passed the flying hidden place.

This fireworks!

It was launched into the sky and exploded.

Isn’t this just a fun thing? What’s the difference between this and burning money?

Both Li Natural and Shen Wanbao were confused.

"Matches, fireworks, firecrackers, and rockets, the price cannot be high. You must be controlled between one or ten copper plates. Just do these. If you can't make money, just come to me."

Chu Tianxiu smiled.

These technologies have low requirements and can be made with current conditions. More companies can also promote the progress of gunpowder technology.

"How to do matches?"

"Use a small wooden stick, stick gunpowder, sulfur, etc. on one end. Then a box containing matches is coated with red phosphorus. Once you rub it, the matches will be lit. Anyway, it is as convenient as possible, and you don't need to hit the flint for a long time to make a fire. You can go back and experiment more."

"Where are the fireworks?"

"Fireworks are more complicated. They need to wrap gunpowder with poor paper and add fire leads. In addition, various metal powders must be added to the gunpowder. When it is burned by fire, different colors will explode. At night, colorful lights will appear in the sky. This requires you to constantly try different recipes."

Li Natural and Shen Wanbao were startled for a while, full of doubts, and immediately went back to study these things.

The cost should be as low as possible, and the quality should be as good as possible.

To create matches and fireworks, it also requires certain technology.

They are not sure whether these things can be sold for money.

...

After the two of them left.

Chu Tianxiu continued to use carpenter tools to tinker with the model of the bronze cannon - first use wood to create the tubes and racks of the cannon.

Small caliber light cannon suitable for field marching.

The carriage can carry a moving car cannon.

A thousand pounds of heavy artillery guarding the city!

He was all focused on casting cannons.

On the surface, the three major civil infrastructures in Jinling City seem to be just civil engineering projects.

But in fact, all steel is used, and a lot of steel is used.

Such a market that is close to you will greatly promote the explosion of steelmaking industry in Danyang County and upgrade.

Gunpowder guns have been developed in Danyang County, and have been repeatedly tested and improved production processes.

Of course, cannons that are more powerful than gunpowder guns can also be invented.

With current technology, it is still extremely difficult to create iron and steel cannon barrels weighing thousands of pounds.

Because the ancient artillery making technology of one-time "watering" was not up to standard, heavy artillery could not be repeatedly beaten like a sword, and there were many sand holes inside, and the iron cannon was prone to bursting and cracking.

The steel technology in Danyang County can only be used to make steel musket barrels, and it is still extremely difficult to make steel cannons.

Bronze is relatively easier.

The melting point of bronze is low, but the watering technology is much more mature.

In later generations, even in the late Qing Dynasty, various bronze cannons were still used.

Of course, bronze cannons also have weaknesses, that is, after repeated firing, the barrel will become softer or even deform at high temperatures.

The temperature of the gunpowder exploded was too high, and the bronze cannon could not withstand the repeated firing.

Moreover, a thousand jin bronze cannon is estimated to cost nearly a thousand taels of silver for copper, which is extremely expensive.

In the end, you have to build a cannon, which is cheap, strong and the most durable.

Prince Xiang Tiange was obviously very interested in these giants that could only be pulled by carriages.

...

"Disciple, Zhuang underestimates the enemy and asks for a meeting!"

The Young Fuzhuang of the East Palace underestimated the enemy, stood outside the gate of Yuyuan, and bowed to ask for a meeting.

At the Military and Military University Campus, he worshipped Xiaohunhou as his teacher in public, and of course he would respectfully call Xiaohunhou as his teacher.

However, he was still dissatisfied and wanted to find faults from "Romance of the Three Kingdoms" to prove that his underestimation of the enemy is not mediocre.

"Come in!"

Chu Tianxiu was bent down to plan the wood, stood up, and said lightly, "What, what else is there?"

The Young Fuzhuang of the East Palace underestimated the enemy and entered Yuyuan. Only then did he see the prince Xiang Tiange on the side, and he was stunned and his face turned red.

"I've met the young master!"

Xiang Tiange was shocked and quickly saluted.

"Well, how is the prince's academic performance?... Forget it, let's talk about it later when you go back to the East Palace. There are other important things to do today!"

Zhuang Qingdi nodded lightly, carrying his hands on his back and trying to give a lecture to Xiang Tiange, but suddenly he remembered that this was Yuyuan, which was not suitable.

He bowed to Xiaohunhou and said embarrassedly, "I have been studying hard recently and carefully studied the Romance of the Three Kingdoms. At the Battle of Red Cliff, I saw Zhuge Liang climbing the altar and borrowing the magical ceremony of the East Wind.

This method seems to be quite similar to the yin and yang disasters and the theory of the magistrate of Moling County, Dong Xianliang, who was entrusted to the altar and asked for rain.

However, you have clearly criticized this theory and said that it is a fallacy theory.

Why did the military Zhuge Liang of a generation used this Yin-Yang method in the book?

You didn't let Dong Xianliang use this method, but you used it in the book yourself. Isn't this a contradiction?

The disciple is puzzled.”

Zhuang Qingdi's face was full of arrogance. He only studied it for a few days before finding a fatal key in "Romance of the Three Kingdoms". It can be seen that his level is also excellent!

Chu Tianxiu was shocked when she heard this.

This farm underestimated the enemy and could actually notice such small details. It seems that he is really studying "Romance of the Three Kingdoms" hard, trying to find faults from it.

"The theory of military philosophies is divided into four major schools: military power, military situation, military skills, military yin and yang.

Among them, the soldiers and Yin and Yang masters are the best at the theory of Yin and Yang.

Zhuge Liang is a military advisor who has become a great military strategist in the Yin and Yang family. It is naturally normal for him to understand the techniques of Yin and Yang and the methods of changing weather.
