The cement factory incident ended up being dropped and no one mentioned it again, but the brick factory incident was brought up.

Luo Zhang was not stingy and directly explained the procedure of how to make bricks. It was up to them how much they could remember.

Everyone was overjoyed when they heard what Luo Zhang said. While listening to Luo Zhang's words, they were memorizing it. No one spoke for fear of interrupting their memory.

But there is still a question in everyone's mind, that is, why did Luo Zhang reveal this formula?

Wouldn't it be to make money for them? Is Luo Zhang so generous?

But no matter what, Luo Zhang has already told the recipe, no matter what he does.

After Luo Zhang finished speaking, everyone fell silent. No one spoke. It was not because they didn't want to say it, but because they were strengthening their memory, for fear that they would remember it wrong and forget it as soon as they spoke.

Luo Zhang ignored them and saluted Li Shimin: "Your Majesty, what do you think of these two things?"

Li Shimin touched his chin and said with a smile: "Yes, yes, it is not an exaggeration to say that it is a divine object. I don't know how you came up with it. How many things are packed in this head?"

Luo Zhang smiled, Li Shimin said this, which means he recognized what he said.

"Then your Majesty agrees to my building a city in Western Turks?" Luo Zhang asked.

"I can only help you recruit craftsmen here. There is no money in the treasury to build the city. If you want to build the city, it's up to you!" Li Shimin said lightly.

But the meaning is very obvious, that is, it is possible to build a city, but if you want me to provide money, there is no way, and labor and capital have no money!

Luo Zhang rolled his eyes. No one else could be so stingy as the emperor, but Luo Zhang was not prepared to ask the Ministry of Revenue to pay from the beginning.

His eyes swept over the officials who were talking and smiling.

When Li Shimin saw this, he knew that Luo Zhang had no good intentions when he told them the recipe of this brick.

"Since you adults want to start this business, I won't stop you, but I have to tell you one thing clearly. The temperature required for firing bricks is very high, and ordinary firewood cannot reach such a high temperature!"

These words immediately made all the officials who were smiling just now look at each other in confusion. They looked at Luo Zhang in confusion. What do you mean, you told us the formula, and now you have a backup plan?

A wise person asked quickly: "Luo Zhang, since you mentioned the temperature, tell us how to bake your brick."

"After all, didn't you burn the bricks you used to build this wall?"

Luo Zhang glanced at the person who spoke. He was also an old acquaintance, Li Daozong, the Minister of the Ministry of Justice. He didn't expect that this old guy had a good eye.

"Master Li, you are indeed powerful. You have discovered this. I do know the solution."

"Master Luo, please tell us!"

"Yes, Mr. Luo, if you send Buddha to the West, it's useless just to give us the formula!"

"Tomorrow we will go to Nanshan. There is good clean coal there. As long as you use that kind of coal, you will be fine. But let me tell you in advance, the clean coal is not much more expensive than the ordinary coal we usually burn.

." Luo Zhang explained.

"Clean coal? Is there such coal?" Everyone's eyes lit up.

They knew the price of coal. After all, many people here were involved in the coal business, but this was the first time they heard about clean coal mentioned by Luo Zhang.

I have thought about it one by one. I will go to Nanshan tomorrow to see the so-called clean coal. After all, if I want to burn bricks and open a brick factory, it does require high temperature to form as Luo Zhang said.

Today, Xiu Mu and Luo Zhang came just for this experiment. Now that the experiment is over and what Luo Zhang said has been confirmed, all the officials have left one after another, preparing to build their own brick kilns.

However, Luo Zhang was kept by Li Shimin and led to the study.

Li Shimin found a rare chair for Luo Zhang to sit on, and then said: "What did you do to cause trouble again? Let them all build brick factories, you will definitely have trouble!"

Luo Zhang immediately cried and said: "Your Majesty, you have wronged me. How could I do harm? I am benefiting the people of Chang'an."

"With those bricks, when building a house or building a pigsty in the future, you don't have to waste time and effort digging out gravel, just use bricks!"

"And with so many people building brick factories, the price will be very cheap, so ordinary people can afford it."

Li Shimin didn't believe Luo Zhang's words. He didn't do any harm or did any good. Would Luo Zhang do it? Stop joking!
