Shi Fu heard Zhao Fengnian ask so, think carefully.

Then he said, "little Lord! This cement material aspect is not rare, the firing method is also simple. There is a point, crushing these raw materials requires a lot of manpower and material resources, if you want to achieve mass production, you must first solve this problem! "

Zhao Fengnian a listen, this is really a problem, cement raw materials have several very hard materials.

Before and after the production need to be crushed into powder, otherwise this effect will be greatly reduced.

It seems that Li Tiezhu will first make some high hardness fine iron grinding skin, and then fix it on the stone roller and grind it with animal power temporarily.

Wait until the spring, and then in the Fengshui River to build a large-scale water roller, water drainage facilities.

Thinking of this, Zhao Fengnian took out his paper and pen and wrote a letter to Li Tiezhu.

After all this, Zhao Fengnian said to Shi Fu, "don't worry, I'll ask Heitie village to make some refined iron utensils here. You should prepare the materials first. In addition, if mass production is carried out, will there be enough manpower here? "

Shi Fu listens to Zhao Fengnian to say the solution. He is pleased and shakes his head when he asks about the manpower.

"Little Lord, there should be enough manpower now. If we are short of manpower, we can go to the castle to recruit. This is not a big problem."

And Shi Fu explained some things, until more than one o'clock in the afternoon, Zhao Fengnian left the workshop and returned to Yongfeng castle.

This trip can be described as a huge harvest, the development of fine iron, crossbow, plow, spring, and steel pipe under development.

In the morning, gypsum was found, cement was made, and tofu was about to be made.

Each of these things can be said to be an important force to promote the development of the territory. With these, the territory will be strong in the near future.

Back to the hillock outside the castle, even at this time, there was an endless stream of carriages. Yongfengbao seems to have the prosperity of a small town.

There is a wide road between the temporary residences to drive four carriages. Although there is a lot of people and vehicles, the carriage still runs smoothly.

Soon the carriage entered the gate.

The scene inside the city gate is more lively, most of which are adventurers and merchants wandering around among the stalls on the street.

Until the Lord's house, the flow of people gradually decreased, but on the road leading to West Street, there was still a continuous flow of people.

Zhao Fengnian, who returned to the Lord's mansion, did not rest. Instead, he asked Li Xuanwu to call Zheng sanpang over.

After Zhou Bing came back, he went to Li Min to discuss the establishment of a new medical department. For this matter, Zhou Bing showed more seriousness and passion than other things.

Zheng sanpang is not too busy now. His disciples can take all the dishes after so long training.

He doesn't have to worry about the restaurant, so Zheng sanpang's daily task is to develop new food and try new food.

This led to Zheng San Pang, who had lost a lot of weight before, successfully restored his original body shape.

Zhao Fengnian looked at Zheng sanpang, who seemed to be fatter than before, and said with a smile: "it seems that life is good recently! I've put on weight again. I've brought you a good thing today

Zheng sanpang has not seen Zhao Fengnian for a long time. Seeing Zhao Fengnian joking with himself, he can't help feeling warm and scratching his head in embarrassment.

However, hearing Zhao Fengnian's last words of "good things", Zheng sanchou's fat body couldn't help shaking, and his small eyes could not help releasing dazzling brilliance.

Looking at Zheng sanpang's excited appearance, Zhao Fengnian does not continue to hang his appetite.

"Come on, let's go to the kitchen!" Then three people and a dog went to the kitchen.
