Chapter 247

The carriage drove slowly to the craftsmanship workshop, which was surrounded by tall courtyard walls, leaving only one gate, which was guarded by two soldiers.

When the soldiers saw the carriage coming, they came out to inquire. However, when they saw Zhao Fengnian in the car, they both showed an incredible look.

Then he knelt down on his knees excitedly. Zhao Fengnian laughed and motioned for them to get up and asked, "where is Shi Fu now? Show me around. "

When the soldiers heard Zhao Fengnian's orders, they did not dare to follow. A soldier led a carriage and went to the workshop.

Because of the cold weather, some embryo making work can only be carried out in warm rooms, so few people can be seen walking in the workshop.

Soon, Zhao Fengnian came to the place where Shifu was located, which was a small kiln. At this time, Shifu was grinding small gray and black particles with iron.

Hearing the movement behind him, Shi Fu raised his head and saw Zhao Fengnian walking out of the carriage.

When Shi Fu saw that Zhao Fengnian was coming, he quickly put down his work and ran to Zhao Fengnian. He said respectfully, "little Lord! Why are you here? I knew I would have gone out to meet you, this... "

Zhao Fengnian waved his hand indifferently: "don't be so troublesome. I just walk around and take a look at the progress of R & D by the way."

Shi Fu actually knows what Zhao Fengnian's purpose is, because he came here for this matter.

At first, when the little Lord told him that there was an object that could solidify sand and stone when it met with water, he was a little unconvinced.

However, all kinds of magic brought by Zhao Fengnian made him insist on believing Zhao Fengnian's proposal.

Through a variety of experiments, indeed produced a new material, water can indeed bond sand and stone, forming a whole, become hard!

But the problem came, after the successful cement added water, it began to set in a few minutes.

This is not enough time for other operations, and it is easy to crack after solidification.

It is far from meeting the nature and requirements described by Zhao Fengnian.

So Shi Fu has been studying the formula, and the result is still the same. Despite this, he has no doubt that Zhao Fengnian's formula is wrong.

Because in his heart, Zhao Fengnian is not wrong, the wrong can only be that he did not find the best match.

Thinking of this, Shi Fu said with some embarrassment: "little master! They are incompetent and have not successfully developed the cement you mentioned. "

Zhao Fengnian saw Shi Fu like this. Although he was disappointed in his heart, he could not blame Shi Fu for this.

After all, Zhao Fengnian had only heard of it, and he didn't know the details.

It is inevitable that research and development is difficult, but now Zhao Fengnian wants to know where the development process is stuck, so as to find a solution to this problem.

Zhao Fengnian patted Shi Fu on the shoulder and comforted him: "Mr. Shi, I don't blame you for this. It's inevitable to develop a new thing. Let's talk about how far the research has come?"

When Shi Fu heard Zhao Fengnian ask this question, his expression was also anxious. Because Zhao Fengnian was there, general problems would be solved quickly.

"Little Lord, you see, this is just fired cement. I have ground it to powder according to your requirements, but the powder is mixed with sand and water..."

Shi Fu reached for a guide, indicating Zhao Fengnian to see the powder he had just ground.

Then Shifu went to the side and mixed some sand and powder with a wooden box.
