Tang Jian also really drank a lot at this time, and he was in a good mood, so Li Muyun didn't refuse to call him uncle.

And Li Muyun took the opportunity to pull the chair to his side, and asked mysteriously, "Uncle Tang, can you stay a few more days this time?" My nephew has something for you to see! ”

"Oh? What is it? Tang Jian asked with interest, but did not say if he could stay a few more days.

He has done a lot of this kind of thing, and at the moment, Datang is strong and Xue Yantuo is weak, and he is still accountable, so he doesn't have to think about time at all, he just goes whenever he wants.

"Cement!" Li Muyun didn't sell it this time, and said bluntly.

"Cement? What is that? Tang Jian frowned and thought about it, but there was no impression in his mind, so he asked puzzled.

"It's something that can build a city quickly, and not only that, but cement can be used to build houses, to build roads, in short, it's very useful." Li Muyun counted with his fingers, but he didn't notice that Tang Jian's face had changed, and as soon as Li Muyun finished speaking, he immediately asked, "What kind of 'cement' did you just say can build a city quickly?" How fast? ”

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

"What? Five to ten times?! You, you ......" Tang Jian was taken aback by the speed that Li Muyun said, shook his head hard, and asked again, "Are you sure you are not wrong?" Five to ten times more? ”

"Ten times the little nephew is not sure, but five times should be no problem, if Uncle Tang is not in a hurry to go to Xue Yantuo, he can stay here for a while longer, and then he can see it for himself."

For things like cement, Li Muyun still has some confidence.

You must know that most of the city walls of the Tang Dynasty are made of cooked clay as the core, paved with a layer of inferior and solid layers, and then add several layers of wall bricks outside after repairing to a certain height.

Some border towns are made of boiled glutinous rice mixed with some special materials, and then mixed with soil to build a city wall, which has a high degree of elasticity, but also has its own disadvantages, that is, it is easy to be inserted by those thick crossbow guns, and after the crossbow guns are inserted, they will become the best climbing tools.

But if you have cement, it's different, just find some planks, nail them into a box, and then mix the cement, sand, and gravel into it in a certain proportion, and then remove the planks after a few days, and immediately you will have a wall that has been built.

Of course, concrete is not necessarily so simple, it also needs to have steel bars and other things, but Li Muyun believes that as long as the supply of iron ore here is sufficient, although it may not be possible to make steel bars, but iron bars can definitely be made, and when the time comes, there should be no problem with replacing steel bars with iron bars in the case of no special requirements for strength.

Tang Jian was a little unsure of what he said when he saw Li Muyun's troubled appearance, and he was a little unsure whether what he said was true, and he was entangled for a long time before he said slowly: "Muyun, what do you mean?" ”

"What I mean is very simple, I want to partner with Uncle Tang to do some business, you also know that the little nephew is low, if he does not do a good job in this cement business, he can be 'swallowed' by others, so I want to find you to rely on this big tree." Li Muyun made no secret of his purpose, and said his purpose very directly.

Tang Jian didn't expect that Li Muyun's purpose for talking for a long time turned out to be this, and he was stunned for a moment, and after pondering for a moment, he asked, "Do you want me to stay for a few more days, but you want me to see the effect of that cement?" ”

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

"Good! Then I'll stay a few more days and see what kind of artifact you are, this cement that is ten times faster than normal city building. After inquiring about Li Muyun's purpose, Tang Jian agreed to his request without any hesitation and decided to stay in the cottage for a few more days.

……

Then Tang Jian and Li Muyun chatted about some things all over the world, one of these two people was a diplomat of the Tang Dynasty, and the other was a killer who traveled south and north in later generations, no one was less knowledgeable than the other, and this chat lasted for most of the night, and there was a sense of sympathy.

And when the two were almost talking, the sky outside was already white, and it was only at this time that Tang Jian slowly calmed down from the excitement just now and yawned a big way.

Li Muyun saw that Old Tang was already sleepy, so he smiled apologetically: "Uncle Tang came from afar, but the little nephew only cared about talking, which really shouldn't be, so he ordered someone to arrange a place for his uncle." ”

"I'm old, I don't have much energy, I think Tang didn't sleep for three or five days, and he never yawned." Tang Jian was bragging about cows, cows, but his body had already stood up and walked towards the outside of the justice hall, although he didn't plan to continue to chat with Li Muyun.

And Li Muyun naturally didn't continue to pull him to chat at this time, just looked at his back, and then raised his hand to beckon a minion and told him to go to the back to prepare the guest room.

However, it was such a delay that Li Muyun missed the best time to know Li Yuan's identity.

……

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

"My identity is kept secret here, understand?" Looking at Tang Jian, who was a little at a loss, Li Yuan said in a deep voice.

"Uh......, Ming, understood!" Tang Jian didn't know what Li Yuan was going to do, and he didn't know why he saw this great god here, so he just nodded and replied mechanically.

Li Yuan snorted, satisfied with Tang Jian's answer, and paused and asked, "Did the second boy send you?" ”

"Yes, yes, Your Majesty knew about Xue Yantuo's invasion, and specially sent his ministers to hold him accountable." Tang Jian didn't dare to hide his purpose, and said honestly.

"What else?" Li Yuan continued to ask.

"Also, there is also the option to buy from Xiaoyao, buy some war horses!" Tang Jian was really stunned at this time, and he told everything about himself without even thinking about it.

"How much?"

"One, thirteen thousand."

"Thirteen thousand?" Li Yuan glanced at Tang Jian: "It's a little less." ”

Some are missing? Tang Jian blinked, and he didn't know what to say for a while, after all, Li Muyun had already agreed to this amount of money, even if it was less, what could he do.

And just when Tang Jian didn't know what to say, Li Muyun walked out of the righteous hall, saw Li Yuan standing outside, and immediately greeted him with a smile: "Dad, why did you get up so early and stop sleeping longer?" ”

Father? Looking at Li Muyun's back, Tang Jian only felt that his scalp was a little fried.

What's going on? When will the Emperor have such a son? How did you not know? Is it an illegitimate child? If yes, it seems .......

was thinking about it, but heard Lao Li Yuan say: "Tang Jian, let me introduce you, this is the old man's righteous son." ”

Righteous son? The devil believes it! Tang Jian blinked, licked his lips, and grinned awkwardly: "Wait for ...... I didn't even know anything about it. ”

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 he didn't know why Tang Jian's face was so pale, could it be that the old man he picked up was really the prince? And is he still a prince of real power?

While thinking about it, Li Muyun said: "Hey, what's this, my father-in-law is my father-in-law, I am me, we have our own friends!" ”

The ghost wants to have his own relationship with you, and Lao Tzu is about to be killed by you!

No wonder this kid detained more than 6,000 war horses, His Majesty the Emperor, who has always been shrewd, would think that he didn't know, it turned out that this war horse was given to his father by the emperor, and this Li Muyun should be the spokesperson of the emperor.

Damn, if I had known this, I wouldn't have made a counteroffer even if I was killed, and I would have given him as much as he wanted, so why make it so embarrassing.

Thinking that the old Li Yuan said just now, 'It's a little less' Tang Jian suddenly felt a wail in his heart, and said to Li Muyun with a wry smile: "That, I'm waiting, it seems that the official in it just now has miscalculated, and the war horse will be at the price you said, 20,000 yuan!" ”

"What? Why? Li Muyun almost couldn't believe his ears, he had seen the buyer bargaining, but he had never seen the buyer take the initiative to raise the price.

"It's nothing, it's so decided, 20,000 yuan is not the same price!" Tang Jian was almost crying, on the one hand, the Emperor Taishang, who told him that his identity was secret, and on the other hand, Li Muyun, who wanted to break the casserole and ask to the end, which made it difficult for him to explain why.

But fortunately, the little minion who went to the back to arrange the guest room came back, and Tang Jian just took the opportunity to step down, pulled the minion and ran to the back mountain, and there was no shadow in the blink of an eye.

Li Muyun watched Tang Jian's back disappear in a daze, and only after a while did he mutter, "Father, what did you just tell him?" How ...... this guy. ”

"Say? Hmph......" Li Yuan, the little old man, snorted with some disdain, pointed to his old face with his finger, and said proudly: "Old man still needs to say? This face alone is worth 7,000 yuan! ”

"Really? Don't lie to me! ”

"What's the good of lying to you?"

"Benefits...... Li Muyun looked at Old Li Yuan, and then looked at the direction where Tang Jian 'escaped' just now, and a flash of inspiration flashed in his mind: "Hey, my father, if you don't think this will be done, I'll find someone to draw you down, and paste a portrait of you in a city, will we be rich then?" ”

"Make a fortune!" Li Yuan was almost not angry with Li Muyun's brain, glared at him fiercely and said, "Remember, you have the old man's seven thousand yuan in your money, don't forget to send it to the old man when the time comes." ”

After that, the little old man ignored the stunned Li Muyun, and left with his hands behind his back, leaving someone there to pat his head with regret!
