About less than ten cubic meters of cement, Jiang Bai added a little iron, made a little steel bar, pressed it, and made a cement pier with red bricks.

"Is this comparable to a stone?" Zhao Gao was very disdainful, "Just this bit of stone foam, I can break it with a slap." ”

Jiang Bai asked him to give it a try.

What should I do if it is broken?

"Breaking it can definitely be broken, according to your skills, it is unreasonable to break this cement pier, the question is, how many masters like you are in the world?" Jiang Bai said, "Moreover, if you use tens of thousands of catties and hundreds of thousands of catties to cast a city wall, can you still fight against it?" ”

Zhao Gao looked at the tall palace wall, he really couldn't help it.

Even land immortals can't destroy a city wall a few feet thick.

But don't you use a lot of materials to make these things?

"After large-scale production, it is difficult to produce hundreds of thousands of catties a day, and tens of thousands of catties are not too big a problem." Jiang Bai said, "Go and try it with a successful force." ”

Zhao Gao slapped it casually, and then fractured.

When Ying Zheng arrived with a large group of people, he saw Zhao Gao holding his wrist and standing in the distance very aggrieved, looking at the small big stone with annoyance.

What's wrong?

"Not only did Zhao Gao break his bones, Meng Yi also suffered a little loss just now, he tried to shoot it without moving, so he used some skill, but he didn't think that he was returned and injured his wrist." A few chamberlains said beside him.

Ying Zheng doesn't believe that just a little bit of dust can have such a big effect?

"One of the most important features of this thing is that it can be mass-produced, think about it, if there is such a large-scale factory in Xianyang, how many tens of thousands of catties can be produced a day? That's a matter of forging a city that doesn't have to look for stones everywhere. Jiang Bai stood next to him and said with a smile.

Yingzheng is still not very optimistic.

"So you'll understand that if we're going to build a city on the grassland, it's better than a stone, right? And if you can find a suitable stone in the area, you can start producing it locally. Jiang Bai introduced to a group of people.

That's kind of interesting.

"Also, some stones that look better are actually more harmful to the human body, and some radioactive materials cannot be found at all, but there is no problem with refined cement." Jiang Bai said, "Okay, let's go back after taking a look, I want to think about how to achieve large-scale production." ”

This is what Yingzheng is most optimistic about.

The materials he used to build the Afang Palace were piled up with human lives.

When a stone is transported from other places to Xianyang, hundreds of thousands of people must die on the way, which is also an important reason why the nobles of the Six Kingdoms scolded Great Qin for being cruel.

But in fact, which of those nobles of the Six Kingdoms didn't enjoy the fruits of human life?

They failed, so they could point to Daqin and say that Daqin was a brutal country.

If you really want to calculate it, this kind of thing is not a problem in the Six Nations at all.

But if cement can be mass-produced in a controlled manner, it will not need to be piled up with human lives, which is a good thing for Daqin's reputation.

But isn't this what Jiang Bai refined with True Yuan?

"If these things can be mass-produced, then can others, such as penicillin, which we don't know about, be able to do it?" Ying Zheng thinks a lot.

It took Jiang Bai two or three days, with his basic chemical and physical foundations, to finally understand the principle of making cement and the principle of configuring the formula of concrete, and then he began to study the precautions and basic requirements for building cement plants in this era.

Hu Hai was next to him to help him tidy up, and it was written that Jiang Bai was a little impatient.

Writing on the cloth did not suit his requirements at all.

"In this era of scarcity, anything that modern people are familiar with is an invention." Jiang Bai had no choice but to start thinking about making writing instruments first.

The brush looks simple, but Jiang Bai really can't take it out quickly.

But in Daqin, there is a brush improved by Meng Tian, and this can be used first.

How to make white paper, but he knows that he has seen many ancient techniques for making paper on TV.

"Let's go, get some straw." Jiang Bai once again planned to leave the palace.

Wheat straw?

Isn't it bark?

Of course, tree bark can be used to make paper, for example, mulberry paper is a very precious paper, which is used mulberry bark.

But what Jiangbai wants to make is white paper that can be mass-produced, a tool that can popularize basic education on a large scale.

He also likes to make crafts, but he doesn't need them.

I'm just a poor ghost, I don't know any art, and the most commonly used by ordinary people is what I want to do the most.

This made Ying Zheng strange again.

It's so easy to find a bunch of wheat straw, but that thing can still make a blank sheet of paper?

Jiang Bai didn't go out when someone sent a large pile of wheat grass, and along with Princess Zhao and Wang Qian's granddaughter, Li Si's daughter all came to see the excitement.

"How do you make wheat straw into white paper? And what's the blank paper? "The little girl of the Wang family is very curious.

Jiang Bai thought about it for a long time and couldn't describe it to her, so he had to follow the procedure in his memory, using handmade instead of machine manufacturing, and it took him half a day to test out enough pulp to use.

With pulp, the next step is simple.

Spread the pulp evenly in a wooden cage to dry.

With the help of internal strength, these are very easy to do.

The sun was in the west, Jiang Bai took a piece of white paper that was not of high quality, tried to write on it, and sure enough, there was a scene of writing a word and rendering it into a pile of ink.

Zhao Gao, who had been squatting next to him for a long time, sneered: "That's it? ”

After getting along with the famous traitor in history for a long time, Jiang Bai often couldn't help but want to beat him.

That mouth is sometimes really vicious and ruthless.

"This is the first blank paper, what more effect do you want?" Jiang Bai said, "Make a bet, if I ...... this thing"

"Not that interested." Zhao Gao jumped to the side like a frog.

You can question what Taifu did, but if you make a bet with him, you will definitely lose.

"It's probably the result of a lack of material." Jiang Bai quickly realized the reason why the white paper he made was unqualified.

Once you have an idea, you can use chemical equations to test it.

In addition, after having martial arts, Jiang Bai's feelings about all existence were not something that ordinary people could understand, and he quickly found a solution to this kind of problem.

Add a little other material to the wheat straw, and this problem can be completely solved.

Thus, the first qualified blank paper appeared.

Jiang Bai lifted the brush and wrote the words "Qin Shi Huang" on it.

Zhao Gao snatched it and disappeared with a swish.

Your Majesty, white paper, good thing!

Jiang Bai: "......"

He thought about it for a moment and then began to make another kind of paper.

Toilet paper.

This is what Jiang Bai urgently needs!
