Chapter 2321

Mu Yun with the sand will burn out the coal, did not wait for her to start, hundred miles of heavy China has already picked out the coal.

At this time, the coal is no longer black, but gray white.

"It doesn't look different." At least there is not much difference in what he sees now.

It's all gray, too.

Mu Yun Di squatted down beside him. "It looks black, and the shape after burning is not different. However, the combustion temperature of coal is much higher than that of charcoal, and..."

Mu Yun looked at the vast desert. "Charcoal needs to be cut and burned before you can get charcoal. Coal itself is buried in the ground. You can get it by digging. It can be used directly without secondary refinement."

They are running a race against time now. They don't have so much time to cut down trees and burn charcoal.

What's more, the supply of charcoal in the capital can only barely meet the needs of the rich every winter.

Not every household can use it.

At this point, it's just a dream to use it to smelt iron in large quantities.

What's more, the most important thing is that they are here in the wilderness. All they can see is sand, stone, not to mention trees. Even a grass is hard to see!

Even if there is a heart burning charcoal, there is no such thing.

A good wife can't cook without rice.

But coal is different!

Although it's not a good thing to dig coal, there are less non renewable resources and coal miners

Mu Yun doesn't want to think about it.

She is not the Virgin Mary, nor is she a great scientist. She is far away from her for generations, whether she wants sustainable development or not.

She can only look at the present!

Live her first!

Live without being killed!

Only live, only have time to think about other, people can not live, but also develop a fart!

Mu Yun did not give Bai Li Chong Hua time to digest. He smoothed an empty piece of sand on the ground with his hands, and his fingers began to draw pictures and explain them.

"I didn't think there would be coal mines here, but if there were coal mines, there might be another possibility, there would be iron mines here! Gold mine and so on... "

"We need people to explore. If iron ore is really found, then we don't need to operate Pankou at all. After all, Pankou is not a long-term thing. After all, if we smooth the wool a few more times, it's time to squeeze out the inventory in their hands."

The rest of the weapons are of little use to them. Mu Yun can even think of the weapons they can have in their hands. It's very rare to have such things as the peerless sword. It's good to have a kitchen knife and a sickle. I'm afraid the rest of them can't be called weapons.

These things they take back are also a burden, do not say, but also punch holes!

Now that they have the ability to do better things, who can look at it.

"We need to find out as soon as possible. Whether there is one or not, we need to build things first. We need to have more pots and pans. The iron burning is similar to that..."

Mu Yun said quickly that the finger's fast painting clearly reappeared the steps of the pouring steel method on the ground.

Rao's mother didn't understand it, but she didn't understand it!

"Little lunar calendar, your mother is so powerful." Little leaf does not understand, but does not hinder her worship.
