Looking at the old Li Yuan with red eyes, Li Muyun twitched his lips, turned around and took a box from Mu Xin's arms and put it on the chessboard in front of the little old man, regardless of whether the chess pieces made of jade would be crushed.

"What is this? I tell you, don't expect a little favor and let me forgive you." Li Yuan rolled his eyes and said.

Li Muyun shrugged: "You can tell if you open it and look at it. If you don't like it, use it as a bet. If you like it, put it away if you always like it."

"What good things can you have?" Li Yuan said, and casually reached out to open the box: "Huh? Centennial old ginseng, where did you get this thing?"

After all, the old man was an emperor, and he was different from a rustic guy like Li Muyun. He just took a look and saw what was placed in the box and asked in surprise.

Li Muyun didn't explain the origin and asked with a smile: "How is it? Is this thing still good?"

Old Li Yuan didn't care where this thing came from, and waved to the eunuch who was serving behind him: "Please take away the things." Only an hour ago, even if Li Muyun wanted to go out to rob, there was not enough time, so Old Li Yuan felt at ease to collect things.

"Tell me, what's going on with you this time? Don't say that you gave me such a thing, you just want to respect me." After receiving the things, Old Li Yuan looked at Li Muyun again and asked.

Li Muyun touched his nose awkwardly: "Dad, why are you slapped me in the face? No matter what, I am also your son. It's not right to be filial to you."

"Oh, it seems that I have really misunderstood you. Since that's the case, you should do whatever you should do."

"Ah?!" Li Muyun didn't expect that the old man was so direct. After a while, he had no other reason, so he could only leave in shame.

I paid for my wife and soldiers, but the benefits were not received, and I also paid for a piece of old ginseng. I felt distressed when I thought about it.

He left the villa area and came to Li Er's palace. After reporting, he was called in.

"Why are you the only one, Ruoxi?"

When Li Muyun found out that he was only here, Li Er instantly changed his face.

"I let the old man stay, saying that I want to gather well, but I'm driven out." Li Muyun spread his hands and said.

As the saying goes, taking money and eliminating disasters. Since the old man has taken ginseng, it must be fine to help him with thunder or something.

Sure enough, when he heard the old man, Li Er changed the topic depressedly: "I heard that someone was sent over Goguryeo?"

Li Muyun nodded: "Yes, a boy from the Wang family in Pingyang has come. He has a sweet-mouthed mouth and is low-key in doing things."

"What are their purposes?"

"I want to buy cement and go back to build a city. As for the rest, I didn't ask. I probably want to verify the identity of that boy Pei Xingjian."

"Cement?" A gloomy flashed in Li Shimin's eyes: "How did you answer him? Could it be that you sold the cement?"

The Tang Dynasty has been using cement to build roads during this period, but this still cannot change the fact that cement can be used to build cities. Li Shimin obviously did not want the Tang army to face the solid city walls in the future.

But Li Muyun's answer disappointed Li Erda: "Yes, why don't they sell it if they give it money?"

"You, don't you know they want to build a city, right?"

"I know, but what does that matter? You don't know how much material you need to use to build a city with cement. If you want to save it through normal channels, you need at least three times the amount, which is all money."

"You know the money, do you know the money? If Goguryeo built a city wall with cement, it would have to be filled with flesh and blood from my Tang Dynasty soldiers."

Seeing Li Muyun's indifferent look, Li Er couldn't bear it and cursed.

This guy knows money all day long, but doesn't know that although money is good, some things are not measured by money.

Li Muyun was scolded and shrank his neck. He had experienced many such things and was used to it. He pretended to be cowardly for a while. After Li Er had scolded him enough, he said: "Brother, don't you really want to wait ten or eight years before flattening Goguryeo?"

"What does it mean?" Li Er was stunned for a moment.

"I mean, we have the final say on how much cement to sell. As long as we limit their quota, it is impossible for them to build a cement city within ten or eight years, let alone what the use of a cement city can be. At worst, it's better to put it there and ignore it."

"Is that your idea? If this is the case, how much money can you make when you sell the little cement."

Li Shimin really doesn't understand Li Muyun's idea. This guy always doesn't play according to common sense. If he doesn't let everything explain clearly, you will never know what he is thinking.

This time, Li Muyun did not hide his intentions anymore, and said with a smile: "Brother, selling things is just for cover. Our real purpose is to inquire about information."

"Think about it, cement always needs to be transported when entering Goguryeo, right? And Goguryeo always needs to build some roads in order to cover up the facts, right? In this way, can we send a large number of detailed works to understand the geographical situation of Goguryeo?"

"When we understand the geographical situation of Goguryeo and understand the climate change of Goguryeo, it is estimated that Pei Xingjian and others have already gained a foothold there and will win over a group of Goguryeo people who are loyal to the Tang Dynasty."

"At that time, we have the right time and place. If there is peace of mind, Goguryeo can be destroyed. Even if it has a few cities built by cement, what if it is gone? Who will care about the few broken cities?

"This..." Li Shimin frowned and thought: "What you mean is that it doesn't matter if you can make money by doing business to inquire about Goguryeo's intelligence?"

"How is that possible! If I don't make money, wouldn't I lose." Li Muyun said in confusion: "In fact, inquiring about information is secondary, and doing business is the main thing."

Li Er suddenly felt that his hands were itchy and tight, and he always had the urge to beat someone up.

Li Muyun seemed to have seen some tricks, and quickly waved his hand and said, "Brother, have we made plans before? We should mess up the Goguryeo economy first and cause turmoil in their country? If we don't make their money, how can we make them turmoil?"

"What do you mean? Do you really plan to continue your business with Goguryeo?"

"Yes, why not continue to make it? Goguryeo thinks cement is good, so we sell it to them. They think glass is good, so we sell it to them. Anyway, those things cannot be eaten as food. Just get their money over, and..."

“And what….”

"And this is not enough. In a short period of time, we must let the Goguryeo people see hope, let them make some money, or make some benefits, and let them get deeper."
