Datang: The prince of salted fish was overheard by Li Er

In order to get rid of the threat of Li You's gaze, Li Shimin hurriedly let Li Junxian go on the road again.

Now that he has obtained the method of taming the cow that he wanted, Li You has become a bit "dangerous" in Li Shimin's eyes.

Whenever Li You looked at him, he felt uncomfortable for a while.

However, Li Shimin was really curious about whether such a method would work.

So what if it's cruel and inhumane, if it works.

As long as these tens of thousands of prairie steers can become the labor force of Datang, Li Shimin is willing to do no matter how cruel things are.

And anyway, a cow is a cow after all.

At this moment, Li Shimin couldn't wait to try it out.

Li You didn't realize that he had been tricked at all, but kept thinking about things that should be done across the board in his heart.

Li Shimin's heart trembled in fear after hearing the voices along the way.

Fortunately, after passing the "accident" scene, the carriage was unimpeded, and soon arrived at the military fortress that Liu Ji and others were repairing.

After arriving at the destination, Li Shimin didn't want to stay alone with Li You anymore.

He was really a little sensitive to Li You's eyes.

After getting out of the car, Li Shimin saw Duan Lun and his group resting outside the fortress.

When they saw Li Shimin's guard of honor, they also rushed over to pay their respects.

"Get up, why are you all outside at this time?"

"How is the restoration going?"

"Is Jiang Guogong here?"

These people were all outside the fortress, which made Li Shimin a little strange, so he asked three questions in a row.

Hearing Li Shimin's question, Duan Lun quickly replied: "Report to Your Majesty, Jiang Guogong will be here soon. This cement is really amazing."

It turned out that in less than half a day, Liu Ji had brought people to restore the fortress.

Now they are all waiting for the cement to dry to see if there is anything missing.

Li Shimin was also amazed when he heard it.

When he said three days ago, everyone felt that it was already an impossible task.

But after using the cement, the restoration work was basically completed in less than half a day.

"Is cement the sticky thing?"

Li Shimin pointed to the cement that had been mixed next to him and said.

Duan Lun nodded quickly and said: "Return to Your Majesty, this is cement. But when we repaired it, we used other methods besides directly using cement to glue it together."

"Oh, if that's the case, then when Jiang Guogong comes, take us in and have a look!"

Li Shimin was also extremely happy after knowing that it was the cement that made the contribution.

However, when Li Shimin looked at Li You, Li You was sitting beside him with an old god.

And after Li Shimin listened carefully to his heart, black lines appeared on his face again.

At this moment, Li You was still thinking about one size fits all.

Fortunately, Jiang Guogong Qu Tutong arrived at the scene soon.

Qu Tutong was excited at this moment.

He didn't stay idle early this morning, but went to the West Market for a stroll.

The Chang'an City of the Tang Dynasty was divided into two halves by Suzaku. On both sides of this central axis, there are East Market and West Market.

The East Market and the West Market were the economic activity centers of Chang'an City in the Tang Dynasty, and they were also the national industrial and commercial trade centers at that time, and they were also important places for economic exchanges between China and foreign countries.

Merchants gather here, shops stand everywhere, there are a variety of items, and the trade is extremely prosperous.

There are many residences of royal families and dignitaries in the squares around Dongshi. Therefore, in the city, "treasures from all directions are accumulated", and the commodities sold in the market are mostly high-end luxury goods to meet the needs of royal nobles and dignitaries.

West Market is relatively close to Kaiyuanmen, the starting point of Tang Chang'an Silk Road, and there are many foreign businessmen living in the surrounding squares, thus becoming an international trade market.

But now, after doing business with the Turks, most of these caravans returning from the grasslands also set up their businesses in Xishi.

After learning about the grassland slaves, Qu Tutong couldn't hold back his excitement early in the morning and came to West Market.

Sure enough, after Qu Tutong walked around, the number of slaves greatly exceeded his imagination.

Qu Tutong immediately made a decision and signed purchase agreements with major merchants.

After hearing that many more slaves would arrive soon, Qu Tutong became even more excited.

In his opinion, with this group of slaves, even if it is impossible to complete all the cleanup of the Guanzhong River, it is enough to clean up a few important places.

With an excited look on his face, Qu Tutong excitedly talked about what he had seen and heard in the West Market after meeting Li Shimin.

After listening to Qu Tutong's narration, Li Shimin was also amused for a while.

This is just a short sleep, Qu Tutong seems to have forgotten the bet between the two of them, completely immersed in his own excitement.

"Jiang Guogong, don't get excited, let's go and see how the fortress is being repaired."

Li Shimin said with a smile.

"Repair? You people are all outside. If you want to repair it, you haven't moved at all."

"I think His Majesty is ready to go in and admit defeat."

"If His Majesty admits his mistakes well, I won't argue with him about the position of the Prime Minister, and I can't embarrass Your Majesty too much."

Qu Tutong was still immersed in excitement, and at this moment he was not ready to argue with Li Shimin anymore.

Li Shimin also saw what Qu Tutong was thinking, so he didn't say anything at the moment, and was going to see Qu Tutong's surprise later.

Soon, the two came to the place where it was first repaired.

After arriving at the place, Duan Lun temporarily acted as an interpreter.

"Your Majesty, Jiang Guogong, this is the first place we repaired today."

In fact, the damage to this place is not serious, but the glutinous rice used to stick the stones was washed away by the rain and became loose.

The repair method here is also very simple, that is, to pry off the loose stones, repair and level them, and then build them up with cement.

After laying, apply a layer of cement evenly on the outside to seal the entire wall.

Since this is the first place to be repaired, the cement on the outside has now dried out, showing a smooth wall surface.

"What, you guys fixed this earlier!"

Qu Tutong couldn't believe his eyes.

He stepped forward, stroking and knocking on the wall to determine its firmness.

If it weren't for the obvious difference between this concrete wall and other surrounding walls, Qu Tutong would definitely think that Duan Lun was joking with him.

But this cement wall is really special, definitely not any kind of craft that Qu Tutong has seen before.

Not only Qu Tutong, but also Li Shimin saw the concrete wall for the first time.

Touching the smooth concrete wall, Li Shimin's eyes were also full of disbelief.

[Hey, a duke of a state, an emperor, look at this person who has never seen the world before. 】

[The cement wall is not only good-looking, it is more like putting a layer of armor on the original wall to make it stronger. 】

[And smooth concrete walls are also more difficult to climb. 】

[However, this is just the ordinary usage of cement. According to Duan Lun, Liu Ji probably showed them other usages later on. 】

Hearing Li You's voice, Li Shimin was full of expectations for the future trip to the fortress.
