When many craftsmen entered the palace, Chongzhen was still considering the relationship between cement and lime.

After all, as a programmer ape who often reads novels on the Internet, it is still very curious to see someone who went back to ancient times and made cement to make a fortune. Although I searched the Internet for how to make cement, I only remembered that lime, clay, and gypsum powder were burned together. As for the steps? Precautions? The program ape said that it was something that engineering dogs should know, what about me? If you can get me a hundred degrees, I dare to study mushroom bombs for you.

As for what if you want to burn cement now? In Chongzhen's opinion, since he remembered these three main materials and knew that they were to be forged, it would be good to leave the rest to the craftsmen as supervisors for headaches. Keep trying, there will always be a day when you try it, and then slowly improve, isn't it?

Wei Zhongxian saw that Chongzhen had been in a daze, ignoring the craftsmen who came in, so he stepped forward boldly and said, "Emperor, the craftsmen have come." ”

Chongzhen, who came back to his senses, looked at the craftsmen. As soon as the craftsman saw the emperor looking over, he knelt down and shouted "Long live your majesty, long live my emperor, long live long live." ”

Chongzhen didn't say that he was exempt from courtesy, and the craftsmen could only continue to kneel on the ground. After a while, I heard Chongzhen say: "I summoned you to enter the palace." but there is a secret commandment. No matter what happens here, it is not allowed to be spread outside, and no one, including your superiors or even the head of the court, even your family members are not allowed to say it. Otherwise, one person knows to kill one, and ten people know to kill ten. The leaker is punished. Do you get it? ”

When all the craftsmen heard this, their hearts trembled. I thought that entering the palace was just the emperor's order, but I never thought that I would do such a fatal thing. However, all the craftsmen still said in unison: "The ministers obey the order." ”

Only then did Chongzhen say, "Get up." This matter has been done well, and I will not hesitate to wait for the knighthood. In addition, I have decreed earlier today that the distinction between peasant households and artisan households will be abolished, and in the future, your children can also study and become officials, and they no longer need to be artisans. It was only tried before Tianjin Wei to see the after-effect. ”

The craftsmen immediately knelt down on the ground and said, "Your Majesty is merciful! ”

After ordering the craftsmen to get up again, Chongzhen said: "Among you and others, there are those who burn lime, those who burn bricks and tiles, and those who burn charcoal. And on this basis, each person is divided into groups and the leader is promoted. ”

After some deliberation, everyone deliberated and proposed, and three craftsmen were selected respectively. One is Zhao Da, who has burned lime all his life, the other is Liu Cheng, who has burned bricks and tiles all his life, and the other is Zhou Zheng, who has burned coal all his life.

Seeing that the craftsmen had finished electing, Chongzhen said: "In all dynasties, the city was built mainly on Sanhe soil. It's just that this thing is not easy to make, and the part-time weather will be cold, and I want to build a martyr's shrine before the snowfall, so this three-way soil is not used.

I once looked through the classics, and I happened to see in a fragment of a book that clay, lime, and gypsum were mixed together and calcined, and one thing could be obtained.

This substance is black and powdery. If it encounters water, it will soon condense and be as hard as iron stone.

It's just that the words in the fragment are ominous, and the method of production is also missing, and it must have been ruined a long time ago.

I thought, the ancients could make it, and I can make it in the Ming Dynasty, it's just a matter of trying a few more times.

This time, he summoned Qing and others into the palace for this matter. If it can be successful, then I will have no worries about Daming City. The secretary will also be knighted and leave a name in history. ”

Just after hearing Chongzhen's words, Wei Zhongxian and Wang Chengen lowered their heads. Others don't know, and the two of them don't know what books Chongzhen used to read. It's nothing more than the rule of three generations that Confucianism wants Chongzhen to see, how can there ever be a remnant of what Chongzhen said?

It's just that Chongzhen is the emperor, since he said that he has seen it, he must have seen it. The first rule of survival in the palace is that the emperor is always right. The second is not to listen to what you shouldn't hear, let alone speak. Otherwise, I don't know how to die.

Just thinking of this, Wei Zhongxian's eyes were fierce, and his eyes were full of unkindness when he looked at these craftsmen, but he planned to evaporate these more than ten people after they were finished. Save yourself from talking nonsense.

Wang Chengen sighed, knowing that Wei Zhongxian had already started to kill. But he wanted to remind the emperor, lest Wei Zhongxian really kill all the craftsmen involved in it in order to keep it secret for the Son of Heaven.

In the next few days, Chongzhen has been paying attention to the progress of cement.

At first, it is useless, no matter how it can't be solidified, it slowly develops to begin to solidify, but the coagulation time required is extremely long, and it is not resistant to heavy blows, and it can often be broken with a small hammer.

Chongzhen, who knew the cement standards of later generations, was of course not satisfied, so the craftsmen continued to try to meet the needs of the emperor.

It's just that no matter how Chongzhen kept it secret, the news that he was playing with mud in the palace still came out, and in the more outrageous gossip, he had become the same as the Emperor of the Apocalypse, but his hobby was a mason!

The mood of the Ming Dynasty and the opposition is like 10,000 grass and mud horses galloping by.

Your brother is a carpenter, and you play with mud? Want to build a house with your brother and play?

Even the people are talking about it. However, compared to the court, the people don't care what your emperor likes to do. As long as the people have food and clothing, it is fine.

The courtiers' impeachment of Chongzhen's unscrupulous work flew into the palace like snowflakes, especially the young imperial history, all of them were like chicken blood, as if Chongzhen did not repent again, and the disaster of the country was in front of him.

Chongzhen, who was so annoyed, simply left all the pieces of impeachment for his unscrupulous work. He also ordered Wei Zhongxian to investigate who leaked the news, and killed a few mouthy little eunuchs directly.

The courtiers who learned that Chongzhen had killed the little eunuch with a cane suddenly quieted down. Only then did they realize that this emperor was no longer the one who had trusted them when they were in the Hidden Mansion.

Now that the factory guards are in the hands of the emperor, the people of Beijing and Xuanda regard the emperor as the son of heaven of Mingjun, and the power is directly chasing Emperor Chengzu, where do the ministers dare to make noise?

After walking for more than ten days, the time was almost the end of October, and the craftsmen in the palace finally came to report to Chongzhen, and the gray powder that Chongzhen wanted, which was called cement, had been largely completed.

Chongzhen, who was overjoyed, hurried to the Luban Palace, but saw that those craftsmen were gathered in front of a cement mound and were amazed.

At this time, the craftsman with a sledgehammer in his hand saw Chongzhen coming and hurriedly threw away the sledgehammer in his hand, otherwise he would lose his head. After kneeling down in a hurry to say goodbye, he also woke up a group of craftsmen.

Seeing this, Chongzhen ordered everyone to calm down, and asked directly, "How is this thing?" ”

Zhao Daxian, one of the three leaders, said: "Back to Your Majesty, this thing was completed yesterday." The piece in front of me was trial-made last night, and now it has been changed to a small hammer to strike, but it can't even leave a mark. The ministers are about to change the sledgehammer to try. ”
