In the fourth year of Zhenguan, the Wa State sent 500 Tang envoys to Datang to study the science and technology, court and 100 craftsmen of the Tang Dynasty.

These people are humble enough, with a smile on their faces, enough to make some people let their guard down on them.

And as the pursuit of the emperor, it is naturally indispensable for all countries to come to the court. Therefore, Li Er was also polite to these Tang envoys, but fortunately, there were still people in Datang who understood.

One of the two who was beaten was called Inugami Mita Yu, who was the chief envoy of the Tang Dynasty envoy this time, and the other one who was beaten was the deputy envoy Huiri Pharmacist.

Or how can we say that these people are not pure-hearted?

deliberately pretended to be stupid, revealed his formation to Ding Changshi, and then took this opportunity to blend into this training ground. It can be said that at a very small cost, it was successfully mixed in.

There is no need to think that Qin Ze also knows what the purpose of these people is, once the gunpowder thing appears, it will definitely attract people with ulterior motives to covet it. And this is naturally indispensable to these people.

Fortunately, both Cheng Laoyou and Tang Jian are shrewd people, so this military stick, Inugami and Mita can only be forced to stand apart.

The rest of the things are not something that Qin Ze can mix, Tang Jian's means are enough for these self-righteous guys to eat a pot of raw food. As for the same short-sighted Ding Changshi, I'm afraid there is no good fruit to eat.

Qin Ze took Li Yuanchang to find a horse, and then directly turned over and straddled the horse. A palm was slapped on the horse's neck, and the war horse immediately galloped out......

Li Yuanchang watched it extremely carefully, especially when the war horse stopped at the end, his eyes widened.

Justice or anything is no longer important, and Qin Ze is not in the mood to dwell on this now.

In this trouble in Hongwen Pavilion, Qin Ze could only obediently go back to copy books. But fortunately, there are two wives at home, so Qin Ze's hand didn't hurt for long, as for how to treat it, then it can't be said casually.

It's just that Qin Ze, who is the prince's attendant, is finally overwhelmed after struggling for half a month.

Although Qin Ze has learned to be well-behaved enough, he can't stand the atmosphere of the private school anyway. But in other words, Qin Ze is still very popular in the private school, and it is them who don't fight or know each other.

Because of that trouble, Li Yuanchang also communicated with Qin Ze from time to time about Danqing, and Qin Ze knew something, but he still relied on his well-informed knowledge and taught him the three views of engineering.

Therefore, now Li Yuanchang has begun to draw all kinds of three-dimensional pictures, especially for houses and the like.

As for Li Chengqian, I don't know if it's because of Qin Ze, but the whole person is also much more cheerful. Even sometimes when there is no one in private, he will directly call Qin Ze a sentence of Brother Qin, and Qin Ze will also reply to him with a sentence of Brother Gaoming.

After getting along for a long time, Qin Ze gradually changed his previous understanding of these young dragons. At least as far as it seems now, these people have not yet reached that terrifying step, and Qin Ze can still feel the temperature of human affection in them.

Of course, Qin Ze has not forgotten his purpose, so he gets along well with the gentlemen.

There are three gentlemen in the private school, one of them is Li Gang, and then Yan Shigu, a bachelor of Hongwenguan, that is, Lu Qu's teacher. There is another one whose identity is more embarrassing, that is Qin Ze's unknown father-in-law.

Among these three gentlemen, Li Baiyao naturally needless to say, his heart must be on Qin Ze's side. As for Yan Shigu, because of Lu Qu, he also took good care of Qin Ze.

Only Li Gang has always treated everyone equally, as long as Qin Ze has a point of overstepping in the private school, it will be a board, so Qin Ze has not been beaten less in the past half a month.

Qin Ze couldn't bear it like this, so after thinking about it, he found an excuse to slip out.

The excuse Qin Ze made was naturally the Military Medical Department. It's been such a long time. Li Er finally handed over the Military Medical Department to Qin Ze, and even sent three hundred craftsmen to allow Qin Ze to build a school in his fiefdom.

Li Er undoubtedly wanted to divert everyone's attention by doing this, and naturally it was impossible to help Qin Ze much. So after just sending three hundred craftsmen, he just let it go.

Building a school requires a lot of money, and Qin Ze now has all his income from the Taiyuan Chamber of Commerce, except for a few shops in Chang'an City. As for the tax revenue of the fiefdom, it was used by Qin Ze to support the dredging of the river.

In this way, it is impossible for Qin Ze to vigorously build a school, and the reason why Li Er does not give Qin Ze money is not that he is afraid that Qin Ze will be too ostentatious.

Fortunately, Li Er didn't really ignore it, and took advantage of Qin Ze's dedication to the ancient artifact, and still allocated 3,000 yuan to Qin Ze. Coupled with the more than 1,000 yuan that Qin Ze won by his own bet, he could barely cope with it.

Qin Ze deliberately built the military medical department in the lower reaches of Jingyang, because it is all saline-alkali land, so it has always been abandoned, so it will not occupy much arable land.

Originally, Qin Ze had sketched out a grand design plan for the Tang Academy in his mind, but now in the face of such a shortage of funds, Qin Ze could only reduce his design again and again.

The area here is huge, and there is a long stretch of saline-alkali land along the Jing River, which is almost 1,000 acres. And the better thing is that the terrain here is very flat. Although because of the terrain, Qin Ze could only build the school into a square, it was already very good.

Although it couldn't be done all at once, Qin Ze still decided to cover the general area first. But then Qin Ze discovered a serious problem, that is, he couldn't find enough stone at all.

The mountains near Chang'an have been almost developed, otherwise when Li Yuan was built a dormitory, Li Er would not have directly brought the stones from his house to repair.

So in this way, Qin Ze was also in a predicament, and in the end, he was forced to be helpless, so he could only start to study the solution.

Since there are no natural stones, Qin Ze plans to make them himself. Red brick and cement are not only easy to make, but also require extremely short production cycles. So Qin Ze also started thinking about this.

If you want to do it, it just so happens that now Qin Ze and Cheng Fu have built several kilns. This was originally used to test the firing of colored glass, but now it can also be used to make Qin Ze tinker with red bricks and cement.

The production of red bricks is much simpler, and loess is everywhere in Chang'an. It just so happened that Wang Daoren was digging and building a reservoir, and Qin Ze also happened to use the loess there to burn red bricks.

So on the first day that these three hundred craftsmen came, they followed Qin Ze to the construction site to make clay embryos. This thing doesn't require much technical content, so it's relatively quick to make.

The true essence of the red brick was firing, and Qin Ze originally thought that it would take a lot of time. It turned out that it took only five days, and after burning down six kilns, the craftsmen succeeded in firing the red bricks.

Come to think of it, for these craftsmen who usually fire official kiln ceramics, it is too much to underestimate them to let them burn a broken brick.

Red bricks are easy to solve, but the cement on the other side is too difficult. Although the raw material of this thing is simple, it is only limestone and clay, but it is much more difficult to fire.

For this reason, Qin Ze also spent five points to figure out this thing thoroughly, and the next thing was to keep firing.

The appearance of red bricks undoubtedly attracted the attention of Cheng Laoyou, and after splitting dozens of red bricks with his bare hands, this guy finally nodded. Then he pulled Qin Ze and began to discuss opening a few more kilns to fire this thing.

Cheng Lao Demon can see the business opportunities of this thing, there is no reason why the eldest grandson can't see it. Compared with Li Er's naked plundering of Qin Ze, the way of the eldest grandson is much gentler, at least on the surface.

So soon the brick factory jointly built by the Jingyang Hou Mansion, the Cheng Mansion and the Changsun Mansion began to be built rapidly.

And during this time, Qin Ze finally got the cement. The craftsmen didn't burn the cement before, but those things either set too slowly or weren't strong enough.

And the reason why it was successful this time was that this craftsman remembered the wrong time of firing. As a result, he burned it for an extra hour in a daze, but it was such a coincidence that he was burned out.

As soon as cement appeared, everything was much simpler. This way, not only do you not have to work hard to mine the stone, but you also don't have to worry about any binders.

In the words of Craftsman Liu, Qin Ze is a downright rough man. Because he completely turned a craft into a hard work.

Now that there is cement, Qin Ze is simply too lazy to use wood. Although the general supervisor failed to make the steel needed for artillery, it was more than enough to make steel bars.

So in this way, Qin Ze's design has to be restarted. Because of the cement slabs, he can now build two-storey or even three-story buildings.

The reinforced concrete cage that Qin Ze had always wanted to escape from now appeared clearly in front of Qin Ze's eyes again, but it made him feel so cordial.

Pavement leveling, sewer construction, and aqueduct design......

Qin Ze is so attentive in every work, and every step is so careful, for fear that something will go wrong in the future.

Now that there are red bricks and cement, Qin Ze also built a cement road directly on the ground. When he saw this thing, Tang Jian, who came to inspect it, was also stunned.

He had never seen a pavement like this before, and he couldn't help but be extremely simple to build. And in terms of sturdiness, it is much better than the bluestone brick road.

So soon the Military Medical Department was also blocked, and without Li Er's permission, no one could get close to here, especially those who sent Tang envoys, it was even more impossible to get close to here.

Because of the reason that it is going to be approaching, Qin Ze is not prepared to build much this time, and it can accommodate about a hundred people. After being built in this way, it does not occupy much area.

Qin Ze was completely focused on this during this time, and the whole person was also busy in the dark, but fortunately, after a month, everything was finally on the right track. And Qin Ze finally began to think about another big thing, that is, his marriage contract with Wang Yuxi.

After so long, it was finally the day of the wedding.
