In the capital, Su Jinli didn't know that Su Xin was rushing back to see her.

She was busy inspecting the finished products fired in the kiln.

Considering that the water vapor in the bathroom is relatively heavy, she asked people to fire tiles and prepare them to be used against the walls and floors.

The tiles are simple and easy to fire, and a batch of finished products has been fired at the kiln factory for further inspection.

However, the bathtub is too large, and the current firing is not very successful, so I have to try again.

The toilet and pipe are finished products, but the flushing effect is not satisfactory enough, and it is also necessary to continue to experiment.

There is also cement, which needs to be ground when calcinating, which is a bit troublesome with the current level of craftsmanship, so it is time-consuming and laborious to make.

The first batch of finished products was not very successful, and now the second batch of finished products has just been made, waiting for trials.

After Su Jinli heard about it, she directly disguised herself as a man and went to the kiln factory, planning to see it for herself.

didn't know that as soon as she arrived at the kiln factory on her front foot, someone on her back foot sent a message to Chu Yan.

In accordance with Su Jinli's requirements, the people of the kiln factory made several cement slabs and concrete slabs of different thicknesses with cement in advance.

Some boards have nothing in them, while others have straw stalks, wire, barbed wire, and steel bars.

There are also walls made of cement and bricks.

and a wall that was plastered with a layer of concrete.

In addition to this, there is also a control group made with conventional materials.

By the time Su Jinli arrived, the cement and concrete had already dried out, just waiting for the next destructive experiment.

Su Jinli checked all the finished products first and felt that it was quite successful.

Just ready for people to start smashing

At this time, Chu Yan came.

When he saw Su Jinli, he was stunned for a moment, as if he didn't know her: "I don't know what this little boy is called?" ”

Su Jinli raised her eyebrows and looked at him, a little unsure, whether Chu Yan was pretending to be stupid, or really couldn't recognize her?

She changed her appearance when she came out, making herself look more like a man.

Chu Yan couldn't recognize her, and it was reasonable to say it.

It's just, why did he come over all of a sudden?

Because the Chinese New Year is approaching, the eldest brother and the second brother have been so busy recently that they can't even see the figure, Chu Yan is the king of Qin, is he too idle?

Su Jinli didn't know that Chu Yan had been really busy recently, but when he heard that she had come to the kiln factory, he left his official duties and came to see her.

After all, the two have not yet gotten married, and if Chu Yan always runs to Wuyang Hou, it will inevitably make people gossip.

So he hadn't seen Su Jinli for some days.

Su Jinli bowed his hand: "Su San, the grass people, I have seen His Royal Highness the King of Qin." ”

Chu Yan saw that she was completely unfeminine, and there was always something strange in her heart, so she couldn't help but ask: "This king sees that you are a little familiar, have we met somewhere?" ”

Su Jinli said without changing his face: "Your Highness thinks that the grass people are familiar, it should be because the grass people look like the second brother Su Yu." The grass people had not met His Highness before. ”

"Really? But how does this king remember that he once saw you in the Taiping Teahouse? At that time, there were a few scholars who were insulting, and you even went to teach them a lesson. As a result, as soon as you left, the desks of those scholars collapsed. ”

Su Jinli secretly gritted his teeth: "Your Highness may have misremembered, the grass people have not been to the Taiping Teahouse. ”

Chu Yan smiled unconsciously: "Really? Then it's when you haven't been. ”

He paused, then changed the subject and asked, "By the way, what is this doing?" These things are all made of cement? ”

In fact, he got the news from the last test, so he knows what cement is for.

Since then, he has been looking forward to the kiln factory being able to make successful cement as soon as possible.

So at this time, he looked at the finished product, and his heart was inevitably a little excited.

If this cement is really successful, it can be used to build walls and dams, and the effect will definitely be very good!

So after Chu Yan teased Su Jinli, he put his mind on the cement test.

The reason why I asked this deliberately was just to take the opportunity to say a few more words to Su Jinli.

Su Jinli has been staying at home recently, and the kiln factory is all Chu Yan's people, so she really doesn't know how much Chu Yan knows about cement.

She thought that Chu Yan should be very busy in normal times, and it was impossible for him to keep an eye on this kiln, so he didn't know that it was possible for these cements.

She explained, "It's really made of cement, now check the effect." ”

After she finished speaking, she nodded at Cinnabar, and Cinnabar immediately ordered to start the experiment.

So two strong men came out, each carrying a hammer, and began to smash the brick wall.

After a "bang-bang-bang" smash, the control group was smashed first.

Then there are the brick walls plastered with concrete.

But this time, without waiting for them to make a move, Chu Yan shouted to stop and replaced them with his two personal guards.

The guards continued to smash the wall.

Because of the plastering of concrete, the smashing time this time is significantly longer.

This means that cement works quite well for building walls, and the brick walls are very strong.

Chu Yan was so excited that he hurriedly asked people to continue smashing.

So next, the guards smashed the made cement slabs and concrete slabs, as well as the traditional control group.

The contrast is stark.

Looking at the last reinforced concrete, in particular, the solidity is simply overwhelming.

The guards changed several times, but their arms were sore, and they couldn't smash it.

The thickness of this board is average, if it is as thick as the city wall, I am afraid that even trebuchets will not be able to take it.

After Chu Yan saw it, his face turned red with excitement.

Su Jinli couldn't help but feel interesting when she saw it.

Who knew that Chu Yan suddenly turned his head and looked at her directly, a pair of eyes were frighteningly bright, as if he might dismantle her at any time.

Su Jinli couldn't help but take a step back.

Chu Yan's eyes were too hot, and she was really worried that he would suddenly pounce on her.

But the problem is, she is obviously a man now!

Did Chu Yan recognize her?

Could he really like men and covet her second brother, right?

Su Jinli hesitated for a moment and coughed deliberately: "It seems that the cement burned more successfully this time, what do you think, Your Highness?" ”

Chu Yan came back to his senses at this time, but the corners of his mouth kept turning up, obviously he was in a very good mood at this time.

He said excitedly: "This king also thinks it's very good! By the way, is there any cement left? If there is, the king will take it to the palace to show his father, and I believe that his father will also like it. ”

When Su Jinli heard this, she couldn't help laughing.

Chu Yan had the heart to help her publicize, of course she was desperate.

It's just that I don't know if Emperor Yong'an will give her some rewards after seeing this cement?

Thinking so, Su Jinli deliberately reminded Chu Yan: "If my sister knows that His Royal Highness is so satisfied with this cement, she will definitely be happy in her heart, and it will not be in vain for her hard work these days." ”

So she's worked so hard, shouldn't you show it?
