Three watches in the middle of the night.

The sky was a little bleak.

However, there is a bright light in the Prince's Mansion.

There is a small lawn planted in the Prince's Mansion, and when spring comes, the grass that had disappeared has sprouted green shoots again, and the whole clearing seems to be a grassland.

Li Chengqian, Changsun Chong and others wore the thick fur coats of the Turks and erected a copper tripod on the lawn.

There is a fire burning under the copper tripod, and at this moment, streams of hot gas are boiling and coming out of the tripod.

With a stream of aroma.

It was the cattle brought by Sugan Chengji that had been slaughtered and put into the dingzhong to cook.

Not far from Dading, there are two Turkic tents, bonfires are lit, and the people are dressed in the costumes of Turkic women, and they are stepping on a carpet, and the two are in pairs, singing Turkic songs and dancing Hu Xuan dance.

Hu Xuan Dance is a popular dance in the Western Regions.

Especially the Hui people, I like it very much.

However, during this period, the Uighurs were under Turkic rule, and the customs of the Turkic people were similar to those of the Uighurs, so the Hu Xuan dance was also popular.

The drums of "Dong Rumble" and the graceful bodies of the shadows danced one after another, and the three of them were fascinated, as if they were enjoying the most beautiful scenery in the world.

The three of them sat on a futon, and in front of them were boiled beef shanks and fine wine.

Watching exotic dances, drinking wine, and eating beef is one of life's great pleasures.

Li Chengqian is a prince of the Han people, but he is a lover of Turkic culture, and he is dressed like a great sweat on the grassland, so he can be said to be the ancestor of the spy of later generations.

Su Gan Chengji was very happy.

Unexpectedly, in this Datang, he could still hear the songs of his hometown and see the dance of his hometown, which simply moved him too much.

Drinking the wine in the glass, he really couldn't help but want to roar twice.

Unconsciously, he felt a little dizzy in his head, as if he had drunk too much wine.

Li Chengqian, who was next to him, saw the appearance of Su Gan Chengji, and a faint smile appeared on the corner of his mouth.

Then, he slowly walked to the side of Su Gan Chengji and helped him up.

"Chengji, I think you drank too much, let Gu Lai help you to rest." The smile on Li Chengqian's face became even brighter.

"Then thank you, Your Highness." Su Gan Chengji said.

"No need to thank you, I hit it off with you, and it would be nice if we could see each other soon." The smile on Li Chengqian's face looked a little mysterious.

Changsun Chong looked at the two with a smile and walked forward slowly.

Then, standing up, he walked over to one of the servants and picked him up.

"Tonight, you're mine." Eldest Sun Chong said with a smile.

Men's style has been popular since the Wei and Jin dynasties, and in the Tang and Song dynasties, although it was not as serious as the Wei and Jin dynasties, there were still a lot of nobles in the upper class.

Li Chengqian helped him and walked into a tent next to him

Two days later.

Li Shimin has just left the court.

A figure ran towards him with a happy face.

"Your Majesty, Your Majesty, it is done, it is done." Li Cheng said excitedly.

The day before yesterday, he sent to the Ministry of Industry and ordered someone to make it.

Now it's finally back.

"Oh, so soon, it's done" Li Shimin was also very happy, and hurriedly said: "Quick, take me to take a look"

Li Shimin was also a little impatient, after all, that thing was something about the world

"Whoa"

Li Cheng answered, and hurriedly took Li Shimin to the Ministry of Industry.

At this moment, Wu Shitong was already waiting for Li Shimin, and when he saw Li Shimin coming, he hurriedly greeted him.

"The courtiers and warriors pay a greeting to your majesty." Samurai Tong said loudly.

Although Wu Shi Tong was named the Duke of the Kingdom, he was actually Li Yuan's party, and his position in the court was a little embarrassing.

Regardless of whether he is or not, in the eyes of Li Shimin, he is the person of the Emperor Li Yuan.

If it weren't for the fact that this guy has meritorious service to Datang and has the ability himself, it is estimated that Li Shimin would have found an excuse to go home to retire.

In the past, when Li Yuan and Li Shimin were opposed, he still had some backers, but now Li Yuan no longer pays attention to the arguments in the court, and goes to give speeches every day instead of playing cards, which makes Wu Shitong feel a greater crisis.

"It turned out to be Ying Guogong, Ying Guogong is not more polite." Li Shimin smiled slightly and said, "Ying Guogong still takes me to see, have you made what I want you to make?" ”

"It's already done, Your Majesty, please go this way." Samurai Tong bent slightly and led the way in front.

Soon, a high wall appeared in Li Shimin's sight.

"Your Majesty, the gluing of this wall is made of lime and mud and sand, which is much stronger than the yellow mud." Samurai walked up to the high wall and said, "Besides, it's a lot faster. ”

"Oh really" Li Shimin was overjoyed, and then he used all his strength to stomp on the wall.

"Bang"

A loud muffled sound was heard, and there was nothing wrong with the wall, but he had to take several steps back.

"Good, good, good, it works, it works, hahaha" he laughed, "Take me to see the cement." ”

"Your Majesty, the place where the cement is made is dusty, and Your Majesty does not have to enter the city, lest it stain your robes." The warrior smiled slightly and said, "Just order someone to bring it out." ”

"It's fine." Li Shimin nodded.

The samurai walked forward, and after a while, he walked towards Li Shimin with two people, two craftsmen, carrying a burden on their shoulders, and the burden was gray powder inside.

"This is cement," Li Shimin was very excited.

This gray thing, I don't know, I thought it was grass ash, but it can really be as magical as Li Tai said

Li Shimin has some expectations, but he is worried that his expectations are too high and he will be disappointed.

"Your Majesty, if the recipe and production method are not wrong, this is indeed cement." Samurai said, he wasn't sure it would work.

Therefore, I dare not say this full, lest I not come back in the future.

"Then what are you waiting for to use quickly, I want to see if it is really the same as what Qingque said." Li Shimin was very happy.

Samurai quickly found the river sand again, and then began to release the water, and mixed it with the cement.

Then, in a rectangle enclosed with bricks, the cement was flattened and the surface was smoothed.

Li Shimin found another branch and wrote the word Zhenguan on it.

"This thing, if it is successful, it should be called Zhenguan mud, prosperous mud." Li Shimin sighed and said.

Then it was time to wait.

Wait for the sun to shine and let the cement dry slowly.

When the time comes, it will be known whether it is really as Li Tai said.
