Master Xi took off his shirt and looked eager to try. He was an iron smelting master in the Metallurgical Construction Bureau. He has been developing it for many years and wants to find something harder than iron.

If you find it, it is an innovation, and there are many places available, such as weapons.

When the same soldiers fight, if you can easily cut off your opponent's weapons, the significance of this is simply immeasurable to the country!

Wang Kang now said boldly that he could make something harder than iron, steel!

What is steel? They have never heard of it.

They also saw the same novelty in the whole process, unprecedented!

Although their suspicion of Wang Kang was reduced, they didn't believe that Wang Kang could be refined!

How many craftsmen in their entire Metallurgical Bureau can do something that a prodigal son can do?

This is simply a fantasy!

Therefore, Master Xi decided to test it himself, and he did not believe that Wang Kang could refine it.

Li Zheng and others also had the same idea. This was not malicious, but normal logical thinking, and no one would believe it.

Moreover, there is a bet between them, which is worth 100,000 gold coins. With these 100,000 gold coins, it can bring better development to the Metallurgical Bureau.

The cooling of molten iron takes time, which is a process of heat dissipation called solidification!

The molds that have been filled are placed on a cart and then transported to another excavated cellar.

Because it is underground, the temperature is very low. There are also several large buckets of water placed here and sprayed on the ground to absorb heat.

This also takes time, including Wang Kang, all the craftsmen are waiting here because this is their first refining furnace.

And they all want to witness whether it is successful.

Wang Kang sat aside and felt relieved, while Li Zheng and others couldn't wait and stared at them.

"Haha, I'm talking to you, is it so urgent?" Seeing this scene, Wang Kang smiled.

After getting along for a few times, the two of them have seen much less, and there is no tit-for-tat confrontation before.

Wang Kang also understood that these people had no malicious intentions, but had an obsession with being an old craftsman.

This kind of trait is very common, and it is found in old scholars.

Hearing Wang Kang's voice, Wang Fuchen walked over and asked, "Young Master Kang, why do you want to make this shape?"

He looked at the long mold, puzzled.

Wang Kang smiled and said, "It is for the support of the tunnel."

"Tunnel support?" Li Zheng listened to the conversation between the two, thought for a while and said, "It really needs support. I have estimated that the width of Dongshan is about two miles and nearly three miles."

"It is necessary to provide support for such a long distance and to be digging in the future, and it must be quite reliable." (Note, one mile was about 500 meters, the same here.)

"Isn't it just that I just use this support?" Wang Fuchen said: "If the mold is poured out, it will be slightly thicker than the thumb."

"Of course not, that's just the main thing, it also requires concrete filling!" Wang Kang said with a smile.

"What is concrete?" Li Zheng asked in confusion. He was a little embarrassed after asking. It was indeed because he asked too many such questions today.

Wang Kang had no reaction and explained patiently: "Concrete is mixed with cement, sand, gravel and other substances..."

Wang Kang said as he used his finger to draw a schematic diagram on the ground, "First put the steel bars upright, then pour the mixing material and finally solidify it. This is called reinforced concrete!"

“Reinforced concrete?”

"Cement is the gray, soil-like things you burn in the south!" Li Zhengdao.

"right!"

Hearing this, the few people were silent and novel, and they had never heard of it.

Li Zhengzhen really wants to ask, after all, you belong to the Ministry of Works, or they belong to the Ministry of Works.

Why are there so many new inventions that are very useful?

After a while, Wang Fuchen sighed and said, "We are here to come to your Xinfeng County this time. At first, we are not willing to do so. It was the order of Lord Shangshu and Lord Director of the Bureau to come."

"Eye-opening, it's really eye-opening."

"Although we are in the Ministry of Works, what we see and know is not as good as you."

Li Zheng also had the same expression, "We have learned what you are going to do these days, open mountains and build roads, and dig straight to the tunnel."

"To be honest, the Ministry of Works of the Court never thought about building such an idea, but you did it!"

"amazing!"

At this time, Master Xi said, "No matter whether the steel you are trying to make will succeed, you will win the bet between us. Increase the furnace temperature and the refractory bricks will also be proven."

"What you use to make molds is what you call high alumina bauxite! We didn't believe you before."

"And that bellow has something else!"

"All things now really make me feel ashamed!"

Seeing a few people talking like this, Wang Kang also stood up and said hurriedly: "Everyone is so serious. I have had some inappropriate words before, so please forgive me."

This is how Wang Kang acts. If others treat him maliciously, he will return it in every way.

But if you are more courteous, you should be respectful.

"No, no, I'll be proud and despise you!" Li Zheng said busy.

After several exchanges, I felt like I had a smile to eliminate my grudges. In comparison, Wang Kang was still willing to deal with craftsmen like Ru Li Zheng and others.

Go straight, as long as you can get recognition, the other side will be consistent.

Several people sat down and chatted while Wang Fuchen looked at Wang Kang and said, "Young Master Kang, since you are going to smelter a large scale, have you discovered an iron ore?"

"I also saw the iron ore during the refining process, and it was obviously newly dug out."

"Yes!" Wang Kang nodded without hiding it, nor could he hide it.

"Sure enough!" Wang Fuchen said: "Outsiders say that Xinfeng County is a barren land, but there are many iron ore deposits!"

"In March, Xinfeng County was not the fief of your Earl's Mansion at that time. A batch of iron ore was dug out and transported to our Metallurgical and Construction Bureau."

"I didn't expect that now I got you and I dug out another one."

At this time, Li Zheng sighed: "Our Zhao State iron ore resources are already small, and the Ministry of Works of the Court only controls two, but they have been mined for many years and are about to become poor mines."

"And most of the rest are in the hands of old nobles."

Wang Fuchen sighed, "Young Master Kang knows why we want the lion to speak loudly and make a bet of 100,000 gold coins with you?"

"Because our Metallurgical Bureau wants to buy iron ore, it's so ironic. It's normal to buy and sell, but do you know? Those old nobles are just waiting for a price by taking control!"

“It’s really hateful!”

Seeing that several people were heartbroken, Wang Kang was also in deep thought. No wonder Emperor Zhao wanted to vigorously cut the price. It turned out that the old nobles all involved so many levels...

The few people chatted for a while, and after a few more hours, the foreman came over, "Young Master Kang's molten iron has completely solidified!"

"Oh? Is it?" Master Xi was so busy standing up, and Wang Kang was also surprised.

The first batch of steel he presided over and finally came out...
