Chapter 858

Coal.

It is the best combustion supporting material that can maintain a constant temperature in addition to electricity, except natural gas and gas.

Give this thing to him now, and Zhang Feng doesn't dare to do it.

That thing will die.

Zhang Feng is not saying anything.

While waiting for Li Qian, he was also thinking of more ways to smelt steel.

There is another way, that is, hammering and smelting, but the time is not enough.

Lao Li promised his sword. It hasn't been delivered yet. No one can see it. Needless to say, the old boy is probably busy flying now.

In a month, if Zhang Feng can't get this thing, he won't even think about the Suiyang emperor's portable sword. Even if Lao Li gives it to him at that time, he's embarrassed.

This steel is a must at this time.

Especially the fire gun.

After getting the fairy ointment, Zhang Feng urgently wanted to make this thing to defend himself.

Not for anything else, just to make it safer to go out in the future. Who knows how many eyes are staring at him under the mountain?

In a moment, Li Chengqian came to the forging workshop out of breath. As soon as he entered the forging workshop, he couldn't stop wiping his sweat with a handkerchief.

While wiping sweat, he also pulled Zhang Feng out.,

"Feng Zi, let's go. Let's find a cool place. Isn't this place too hot?"

A group of five people went out of the forging workshop and felt comfortable and inexplicable.

At this time, Li Chengqian asked, "why did you come to me? Did you get the steel out?"

Zhang Feng shook his head and asked, "let me ask you, have you heard of coal?"

Li Chengqian looked at Zhang Feng in surprise and nodded.

"That's easy. Now you find some people to get me ten carts of coal. I'm in urgent need."

Li Chengqian was confused: "Feng Zi, do you know what that thing is for?"

"Who can burn a fire?"

Zhang Feng grabbed Li Chengqian's handkerchief and wiped the black sweat on his forehead.

Li Chengqian had some heartache, but he couldn't care.

Li Chengqian naturally knows about the coal, but only some people in the palace and some dignitaries can afford it. And where can I get it at this time?

Who will dig coal for him in such hot weather?

The most important thing is that this thing is not called coal, but charcoal. Li Chengqian guessed something in his conversation with Ma Zhou on the road.

"Feng Zi, do you know that not everyone can afford this thing?"

When Zhang Feng heard the speech, his face was full of question marks

"Isn't the sleeping trough just rotten coal? It can't afford it?"

Li Chengqian had a big head and pointed to Ma Zhou: "tell him, I'm a little flustered."

Ma Zhou was also a little confused, but Li Chengqian spoke, and he could only whisper: "mentor, apart from the use of the palace, princes, ministers and kings, few people are qualified to use this thing, as well as the price of coal..."

"How many cars?"

Zhang Feng remembered that this was in the Tang Dynasty, not later generations. In later generations, a bag of anthracite was only 70 yuan, but many people still couldn't afford it.

Ma Zhou stretched out two fingers and compared them with a scissors hand.

"Two thousand through a car!"

"So expensive?"

Zhang Feng was also a little surprised.

"Li Qian, how much money is there in the account now? Can you buy ten cars?"

Hearing the speech, Li Chengqian sighed, looked at Zhang Feng like an idiot and said, "he said two thousand through one stone!"

"And in this weather, unless it's winter, at this time, no businessmen sell this thing. The most important thing is that this thing is now basically in the hands of Wang in Taiyuan... Even if the emperor wants to, he has to send a document in advance..."

Five surnames and seven looks?

Zhang Feng's eyelids jumped when he heard the speech.

It's really hard to do.

The eight families in Guanlong controlled the business road, and the five surnames and seven hopes controlled all the mineral veins and grain industries in the Tang Dynasty. This matter has been clearly recorded in history.

With a little hint, Zhang Feng understood in an instant.

However, the iron and steel business has been carried out to this point. Wouldn't it be a joke to drop the challenge at this time?

And this charcoal is really not good. It's OK to play with molten iron to melt glass and other things. If you want to refine steel?

Then you have to get coal.

Zhang Feng had a headache

He really didn't know that Datang's coal mine was under such strict control.

Zhang Feng asked: "in addition to the Tang Dynasty, can there be coal mines in Tubo and Tuyuhun?"

"Yes, but now the situation of Tubo..."

"Then immediately ask your family to find a way to get some for me. Anyway, I put my words here. There is no coal, let alone a fire gun. Even if it is a spear that has nothing to break, I can't get it out!"

Chengqian was surprised.

Ma Zhou, as well as alchinnon and Moco Addo, were also shocked at this time.

A spear without breaking anything?

What's this?

And this fire gun, what is it?

Are these two things that haven't stopped listening to what the dean said that day?

They couldn't help burning a little flame in their eyes.
