Tang Jian was really drinking too much at this time, and in a good mood, Li Muyun didn't refuse to call him uncle.

Li Muyun took the opportunity to pull the chair toward him and asked mysteriously: "Uncle Tang, how many more days can you stay this time? I have something for you to see!"

"Oh? What's it?" Tang Jian asked with interest, but did not say whether he could stay for a few more days.

He has done a lot of things like this when he is on a mission. Now the Tang Dynasty is strong and Xue Yantuo is weak, and he is still taking accountable, so he doesn't have to consider the time issue at all. He just goes when he wants to go.

"Cement!" Li Muyun didn't keep it a secret this time and said bluntly.

"Cement? What is that?" Tang Jian frowned and thought for a while, without any impression in his mind, so he asked in confusion.

"It is something that can quickly build a city, and not only that, cement can also be used to build houses and roads. In short, it has many uses." Li Muyun counted with his fingers, but did not find that Tang Jian's face had changed. As soon as Li Muyun finished speaking, he immediately asked: "What 'cement' did you just say can quickly build a city? How fast is it?"

"Well..." Li Muyun thought for a while: "I don't know how fast it is, but I think it should be at least about five to ten times!"

"What? Five to ten times?! You, you..." Tang Jian was startled by the speed Li Muyun said, shook his head hard, calmed down and asked again: "Are you sure you were not wrong? Is it five to ten times?"

"If you have ten times, I am not sure, but five times should be fine. If Uncle Tang is not in a hurry to go to Xue Yantuo, he can stay with me for a while and you can take a look at it myself."

Li Muyun is still a little confident about cement.

You should know that most of the city walls of the Tang Dynasty are made of cooked clay as the core, with one layer of inferior and one layer of solid. After the construction reaches a certain height, several layers of wall tiles will be added outside.

Some small border cities use boiled glutinous rice and some special ingredients to mix it with soil to build a city wall. Such a city wall is extremely elastic, but it also has its own disadvantages, that is, it is easy to be inserted by thick crossbow guns, and after being inserted, it will become the best climbing tool.

But if there is cement, it is different. Just find some wooden boards, nail them into a box, and then mix the cement, sand and gravel together in a certain proportion and pour them in. After working for a few days, the wooden boards will be removed immediately. It will immediately be a wall that has been built.

Of course, concrete is not necessarily so simple. It also needs steel bars and other things inside. However, Li Muyun believes that as long as the iron ore is sufficient, although steel bars may not be able to be produced, iron bars can be produced. At that time, there should be no problem if there is no special strength requirement.

Seeing Li Muyun's serious look, Tang Jian was also a little confused about whether what he said was true. After struggling for a while, he slowly said, "Muyun, what do you mean?"

"My meaning is very simple. I want to do some business with Uncle Tang. You also know that my nephew is humble. If you don't have a good business in this cement business, you will be 'swallowed' by others, so I want to find you, a big tree to rely on." Li Muyun did not hide his purpose at all, and directly expressed his purpose.

Tang Jian didn't expect that Li Muyun's purpose was this after talking for a long time. He was stunned for a moment, and then pondered for a while and asked, "Do you want me to stay for a few more days, but do you want me to see the effects of that cement?"

"That's true, I wonder if Uncle Tang is willing?"

"Okay! Then I'll stay for a few more days to see what kind of magical object you are, which is ten times faster than normal building. "After inquiring about Li Muyun's purpose, Tang Jian agreed to his request without any hesitation and decided to stay in the village for a few more days.

...

Then Tang Jian and Li Muyun talked about some things from all over the world. One of them was a diplomat of the Tang Dynasty and the other was a killer who traveled around the world in later generations. No one had less knowledge than the other. This talk lasted for most of the night, and he felt a sense of mutual appreciation.

When the two were almost chatting, the sky outside had turned pale. It was not until this time that Tang Jian slowly calmed down from the excitement just now and yawned a big yawn.

Seeing that Old Tang was already sleepy, Li Muyun smiled apologetically: "Uncle Tang came from afar, but his nephew was just talking. It really shouldn't be so he ordered someone to arrange a residence for his uncle."

"I'm old and have no energy. I remember that Tang didn't sleep for three or five days, and never yawned." Tang Jian was joking with a bull, but his body had already stood up and walked outside the Juyi Hall, although he didn't plan to continue chatting with Li Muyun.

At this time, Li Muyun naturally would not continue to drag him to chat. He just looked at his back, then raised his hand to call a minion and told him to go to the back to prepare the guest room.

However, after such a delay, Li Muyun missed the best time to know Li Yuan’s identity.

...

Outside the Juyi Hall, Tang Jian, who had originally wanted to come out to breathe, opened his mouth in surprise and looked at the little old man in front of him. His smell of alcohol was instantly scared away: "Too, too, too..."

"My identity is kept secret here, do you understand?" Li Yuan said in a deep voice as he looked at Tang Jian who was at a loss.

"Uh..., Ming, understand!" Tang Jian didn't know what Li Yuan was going to make a fuss, nor did he know why he saw this great god here, but he just nodded mechanically and answered.

Li Yuan nodded, showing satisfaction with Tang Jian's answer, and asked, "Did you send you to me?"

"Yes, yes, Your Majesty knew that Xue Yantuo was invading, so he specially sent his ministers to hold him accountable." Tang Jian did not dare to hide his purpose and said honestly.

"What else?" Li Yuan continued to ask.

"And, I'll buy some war horses from Xiaoyaohou!" Tang Jian was really shocked at this time, and he told everything about him without thinking.

"How much?"

"One, ten thousand three thousand guan."

"Ten Thousand Three?" Li Yuan glanced at Tang Jian: "Somewhat is missing."

Some are missing? Tang Jian blinked his eyes and didn't know what to say for a moment. After all, Li Muyun has agreed to the amount of money now, so what can he do if he is less?

Just when Tang Jian didn't know what to say, Li Muyun walked out of the Juyi Hall and saw Li Yuan standing outside, and immediately greeted him with a smile: "Dad, why are you getting up so early and not sleeping for a while?"

Dad? Looking at Li Muyun's back, Tang Jian felt that his scalp was a little explosive.

What's the situation? When will the Supreme Emperor have such a son? Why don't I know? Could it be an illegitimate son? If so, it seems...

Just as he was thinking, he heard Old Li Yuan say, "Tang Jian, let me introduce you to me, this is my adopted son."

Adopted son? What a genius believe! Tang Jian blinked his eyes, licked his lips, and grinned awkwardly: "Xiaoyaohou... I hide this matter so tightly, but I don't know at all."

Li Muyun didn't know Li Yuan's true identity, but in his opinion, Li Yuan could know Yu Zhining, so it seemed reasonable to know Tang Jian. But I don't know why Tang Jian's face turned so pale. Could it be that the old man he picked up was really a prince? And he was a real prince?

While thinking, Li Muyun said, "Hey, what's the matter? My adoptive father is my adoptive father, I am me, we all have their own friends!"

The genius wants to make friends with you, I am about to be cheated to death by you!

No wonder this kid detained more than 6,000 war horses. His Majesty, who was used to being smart, would think that it was unknown. It turned out that the war horses were given to him by the emperor, and Li Muyun should be the spokesperson of the Supreme Emperor.

Damn it, if I had known this before, I wouldn't have bargained just now even if I beat you to death. At worst, he would give you as much as you say. Why do I have to be so embarrassed?

Thinking of Old Li Yuan saying 'a little less' Tang Jian suddenly felt a wailing in his heart, and he smiled bitterly and said to Li Muyun: "Well, Xiaoyao Hou, I just thought I had made some mistakes in it. That war horse will be at the price you said, 20,000 yuan!"

"What? Why?" Li Muyun could hardly believe his ears. He had seen the buyer bargaining prices, but had never seen the buyer take the initiative to raise prices.

"It's nothing, it's just settled, 20,000 yuan is worth no less!" Tang Jian almost cried. On the one hand, he told his identity that the Supreme Emperor was confidential, and on the other hand, he wanted to break the bastard and ask the whole story. This made it difficult for him to explain why.

Fortunately, the minion who was arranged by the guest room at the back came back, and Tang Jian took the opportunity to step down, pulled the minion and ran to the back mountain, and in the blink of an eye there was no trace.

Li Muyun stared at Tang Jian's back disappearing, and then murmured for a while: "Dad, what did you say to him just now? Why is this guy..."

"Say? Hum..." The little old man Li Yuan snorted with some disdain, pointed at his old face with his finger, and said proudly: "I need to say it? Just this face is worth 7,000 guan!"

"Really? Don't lie to me!"

"What are the benefits of lying to you?"

"The benefits..." Li Muyun looked at Old Li Yuan, then looked at the direction where Tang Jian had just 'escape', and a flash of inspiration flashed in his mind: "Hey, my dear father, why don't you think this will happen? I'll find someone to draw you and post a portrait of you in a mansion. Will we get rich by then?"

"Make a fortune!" Li Yuan was almost angry with Li Muyun's imagination. He glared at him fiercely and said, "Remember, you have 7,000 stakes of money in your money. Don't forget to send it to me at that time."
