After seeing off Gao Heng, Li Muyun thought about it for a long time, and finally decided to tell Li Shimin about this matter.

After all, it was a business of two million yuan. Perhaps hundreds of years later, the Ming and Qing dynasties might not be a big deal, but it was definitely not a small amount during the Tang Dynasty.

The next morning, Li Shimin had just gotten up and was moving his muscles in the yard, and heard someone coming to report to King Xiaoyao for a visit.

Although he didn't know what Li Muyun's purpose was, he still ordered: "Let him come in."

"No!" The eunuch Lao Long responded and went out. Li Muyun followed him into Li Er's yard.

"Tai Chi? How can the emperor still hit this thing?"

After entering the yard, Li Muyun looked at Li Er who was slowly punching a set of fists and asked in surprise.

Li Shimin was stunned for a moment: "Tai Chi? What is that?"

"Isn't the emperor's fight?"

"I am not learning and ignorant. This is the Five Animal Show that I am fighting, which was created by Hua Tuo in the Eastern Han Dynasty." Li Shimin really had no choice but to take this brother, and he didn't know anything and always liked to express his opinions randomly.

"..." Li Muyun touched his nose speechlessly, and afterwards he thought about it, he really made a mistake.

Tai Chi was said to be created by Zhang Sanfeng, which is several hundred years away from the beginning of the Tang Dynasty.

But then again, Li Er’s actions just now were indeed quite similar to Tai Chi, such as card swiping, card scoring, card touching, and playing cards. He was obviously a veteran.

"Tell me, what's the matter with me so early?" After a while, Li Er finished a set of Wuqin dramas, took the towel handed over by the old eunuch, and said while wiping sweat.

"That's it..." Li Muyun said Gao Heng's request in simple language and focused on two million yuan.

Li Shimin didn't say anything at first, and only then asked thoughtfully after hearing Li Muyun's words: "So that the memorial you handed over to upgrade your arms was prepared for this matter?"

"Hehe, that's right, not." Li Muyun smiled embarrassedly: "Isn't this going with the flow? If it weren't for the proton Gao Heng's proposal, I wouldn't have remembered it."

Li Er's face was eccentric: "Is that so? Have you ever thought about it? What if Goguryeo uses the equipment he bought to deal with us? Two million coins can arm the army of 200,000 people."

"Brother, don't we have more advanced things, just like that gunpowder, don't tell me that you're just using that thing to make fireworks."

When Li Muyun talked about gunpowder, Li Shimin was so angry that he didn't fight.

"Although the gunpowder you made looks good, it has no use except for bombing the city gate. Do you have the nerve to say?"

What? It can only be used to bomb the city gate? What does this mean? Li Muyun scratched his head and asked, "Brother, you wouldn't have packed the gunpowder with a cloth and then used it directly?"

"Otherwise!" Li Er asked back angrily.

Li Muyun slapped himself on the forehead: "Brother, it's a waste. Is that gunpowder so useful?"

"No, then how do you think you should use it." Li Shimin sat down on the stone bench in the yard and pointed to another one.

As one of the few emperors in history, Li Erguang accepted good advice and was ashamed to ask questions, adding a lot of points to him.

Li Muyun, who originally thought he would be scolded, was moved by Li Er's attitude. After sitting down, he said seriously: "Brother, let's not talk about other uses. Even if you wrap it directly with cloth, I think if you put some iron sand and other things inside, it can cause considerable destructive power."

"In addition, if you create a thin iron box, put the gunpowder in it, and throw it into the crowd, it can also cause a considerable lethality."

"Even if it's a little worse, digging a hole in the ground and burying gunpowder into it, the large troops used to ambush the enemy can also play a significant role."

"Oh? Can it still be used like this?" Li Shimin's eyes widened in an instant, revealing a look of interest.

"Of course it can be used like this, you know that when I was in Shuozhou, I used gunpowder to ambush Xue Yantuo tens of thousands of people." Li Muyun said with a wry smile.

He really didn't understand why so many people in the Tang Dynasty actually took gunpowder and didn't know how to use it. No wonder our country invented it early, but it turned out that it was used by foreigners to open China's doors.

Li Er recalled what happened before, frowned and asked, "Then why didn't you say it earlier?"

Li Muyun showed a constipation-like expression, thinking that who knew you, the country bumpkin, wouldn't even use gunpowder. If I had known this, I would have written a manual for you.

But after thinking about it, the words turned into: "Brother, you should be careful about the application of gunpowder. This thing is too powerful, far exceeding cold weapons. If there are too many people who know it, it will probably have a bad impact."

Li Shimin also knew that this was an excuse. After all, someone had already given out the things, and you didn't know how to use them randomly, no one could blame others for using them.

It’s like a blacksmith hitting a knife. If you buy it home and chop it up, you will hurt yourself. No wonder the blacksmith is the same.

He simply nodded and said, "Well, you said that, but there is some reason. But now there are no outsiders, so you can explain it in detail. I want to know what the use of gunpowder is."

Li Muyun smiled bitterly and said, "The use of gunpowder is actually to make cannons and muskets at the moment. However, the quality of the steel in our Tang Dynasty is not up to standard. Even if it is made, it will not be very useful. If it is not done properly, it will hurt the enemy by 1,000 and damage it by 800."

"Arson and musket? It sounds quite powerful." Li Er showed an interesting expression.

This does not mean that Li Er doesn't care about the damage to the war. In fact, fighting cold weapons is a way to hurt the enemy by hurting 800 by himself. He fights with small numbers and burns the camps. This is basically a story about the inside. In most wars, both sides are actually competing for the number of people and will.

Li Muyun has experienced several wars and is also aware of the situation of the cold weapon war. He did not think how Li Er was cold-blooded and said frankly: "In fact, artillery and muskets can be understood as the same thing, the difference is that they contain different amounts of medicine. Their principle is to use steel to create a sturdy barrel, put gunpowder and metal balls in, and then rely on the impact of the explosion to throw the metal balls out to attack the enemy."

Li Shimin thought about it and said with some uncertainty: "Then according to your opinion, wouldn't this thing be different from the Eight Niu Crossbow and the Castile Cart?"

"In some ways, the difference is not big, but in terms of attack power, gunpowder is much stronger than the two things you mentioned by the emperor."
