Datang: Rebirth of Li Chengqian, the beginning of the treason interrogation

Chapter 56 Cement Formula Ratio Leads the Era
"Since Your Highness has said so much, I, an old man, will definitely teach you everything I know."

Li Jing nodded. It would be a good thing to have one or two more people to inherit his mantle.

"Thank you, Duke!" Pei Xingjian bowed quickly. To be able to receive guidance from the God of War is something that many people wish for!

"Xingjian, why don't you change your words?"

Li Chengqian looked at the scene in front of him and a smile appeared on his face.

Hearing this, Pei Xingjian was stunned for a moment, but he quickly reacted and bowed again, saying, "Thank you, teacher!"

What he didn't know was that Li Chengqian had raised his generation level and made him a junior fellow student of Su Lie and Su Dingfang, rather than a disciple.

After settling Pei Xingjian, Li Chengqian said goodbye and left. After all, he had other things to deal with and couldn't stay here for long.

Li Jing also began to teach Pei Xingjian, preparing to pass on his knowledge of military strategy to him.

But this also depends on talent. Li Jing's two sons did not inherit much military knowledge.

After returning to the Eastern Palace, Li Chengqian, in addition to necessary training, devoted himself to scientific research.

"Why not?"

Li Chengqian looked puzzled. He half-knelt on the ground, carefully observing the pool of plaster in front of him, as if trying to find the answer from it.

Wang Xiao, who was standing by, reminded anxiously, "Your Highness, there is a court meeting today!"

Li Chengqian didn't even raise his head, still concentrating on the plaster in his hand, and replied casually: "It doesn't matter, as long as His Majesty is in the palace, it doesn't matter whether I go or not."

After saying that, he continued to immerse himself in his research.

"It's made from limestone, laterite and iron ore fired together, so it shouldn't go wrong."

Li Chengqian muttered to himself while gently rubbing the lump of plaster with his hands, seeming to be lost in thought.

After a while, he suddenly raised his head, with a gleam of determination in his eyes: "There must be something wrong with the ratio, it needs to be readjusted!"

Then he began to direct the craftsmen around him to get busy again.

"Your Highness, may I ask you a question? What are we forging? I have been a blacksmith all my life, but I have never encountered such a way of burning iron."

An old blacksmith asked with a smile. His name was Shen Lin. He had been making iron forges for more than 40 years and his skills were very sophisticated. He could make any weapon in his hands in a very short time.

However, after more than ten days, Li Chengqian failed to succeed in refining the thing they had been trying to teach him.

"This thing is called cement. If it can be successfully refined, it will be more powerful than any other equipment."

Li Chengqian showed a hint of excitement on his face, but more of it was anxiety. He was still racking his brains to recall the process of refining cement.

"Grind this stone, add seven parts, two and a half parts of red clay, and half part of iron ore."

Under Li Chengqian's personal command, the powders were quickly put into the furnace using iron tools. Not long after, they were all burned red, like molten iron.

"cool down!"

Following Li Chengqian's order, the blacksmiths acted quickly, pouring the melted liquid into a large iron bucket and quickly cooling it down with cold water.

The iron bucket was lifted up, and thumb-sized round particles appeared one after another, all jet black.

Li Chengqian was delighted when he saw this. "It's done, it's done, it must be done, grind these little black particles into small pieces."

A group of blacksmiths had no choice but to do as they were told and grind all the black stones into powder, then add water.

It didn't take long for the powders to condense together again and form a hard lump.

"It's done, remember the recipe!" Li Chengqian was ecstatic.

"Your Highness, I've made note of it!" Shen Lin nodded. "Reward, big reward!" Li Chengqian continued.

"Commander Wang Xiao, find a vacant lot outside Chang'an City and we'll start refining cement."

Cement would have played a vital role in ancient times and would have been a great miracle.

"Shen Lin, you are experienced. From now on, you don't need to forge iron. You all go and make cement for me. I don't care how you make it or how many people you need. I just want you to make something like this."

Li Chengqian pointed to the small particles (clinker) on the ground that had not been ground yet. He was able to research the formula, which was already stealing the achievements of others. As for the technical design, it would definitely not be difficult for these ancients.

Shen Lin was in a dilemma as he stopped working as an ironsmith. He was not good at making cement, but he still took the job despite gritted teeth.

"Don't worry, I won't treat you unfairly. All of you will receive a monthly salary of 30 taels of silver."

If you want the horse to run, you must feed it grass.

The production of the wine and beverage industry has already brought the Eastern Palace considerable income.

"Please rest assured, Your Highness. We will do our best."

A group of blacksmiths suddenly became very motivated.

at the same time.

Several uninvited guests came to Chongwenguan.

"What's going on? How did a good Chongwen Hall become like this?"

Li Shimin walked into the Chongwen Hall, wanting to witness the talents of the students in the Eastern Palace, but he only saw mud all over the ground.

There is no elegance at all. Is this still Chongwenguan? Is this still the Eastern Palace?
"Who are you? This is the important area of ​​the East Palace!" When Luo Binwang saw a few people, he immediately went up to them and scolded them. They were covered in mud and looked more like farmers who had just finished plowing the fields.

Li Shimin's face was gloomy. It had been a while since he saw Li Chengqian come to the morning court. He felt something was wrong, so he came to the East Palace today to see what was going on.

"Longwu Guards, take these people away! No one is allowed to enter here without your Highness's order."

Seeing no movement, Luo Binwang shouted again.

"Humph!"

Li Shimin snorted coldly and walked straight past the other person.

"You dare!" Luo Binwang was about to step forward to stop him.

Then he was grabbed by a pair of big hands and pushed away violently.

"Be honest, or don't blame me, Old Black, for being rude!"

Yuchi Jingde's eyes were wide open with anger, and the students were so frightened that they dared not step forward.

"Your Majesty, from my perspective, there must be some other reason. Why don't we go somewhere else? This place is so dirty and messy."

Cheng Zhijie took a few steps forward and stood in front of Li Shimin.

"I want to see what this rebellious son has been doing here since he hasn't come to court for so long."

Li Shimin was a little angry. He was obviously a perfect prince, but now he has fallen? This made him disappointed again.

"The East Palace is a restricted area, no one is allowed to enter. Don't force us to take action!"

In front of the Chongwenguan Hall, a row of students stood, looking at Li Chengqian, Cheng Zhijie and Yuchi Jingde with unfriendly eyes.

Behind this is the biggest secret of their Chongwenguan, which will allow them to go down in history. Before it is made public, they will not allow anyone to enter and steal their achievements.
