Honeycomb coal is such a thing, and the price will not be too high!

Because this thing can only cook, Ningbei will give it a heating effect after holding it to death.

But firewood can do the same.

Although firewood is not as effective as honeycomb coal, the people do not pay much attention to it.

All they want is to make do with it, so the price is set here.

But don't forget, honeycomb coal is a one-time consumable!

You have to burn two or three honeycomb coals to cook once, right?

You have to use a honeycomb coal to boil water once, right?

You have to use ten honeycomb coals a day, and if you don't have them, you have to buy them again, so this thing takes the route of more and more profit.

Compared with meat, poultry, vegetables and fruits with the same low volume and long growth cycle, the biggest advantage of honeycomb coal is that as long as you find a coal mine, you can make it in large quantities.

High consumption and easy to make.

This kind of business with low profits is what Ningbei wants.

Moreover, he still made honeycomb coal more than a thousand years in advance, and he no longer has to worry about firewood in the future.

It can be said that it is a solution.

As for whether the coal mine can be mined, why not just spend some money to buy this mountain?

A mountain with a mine must be expensive, but it's cheap to just buy a mountain, especially in a remote mountainous area where no one cares about you!

In ancient times, there were no monitoring and satellites, and the management model for remote areas was also very loose.

Moreover, the mountains with mines are often in remote areas, which can be said to be unique.

So the only difficulty in making honeycomb coal is to find a coal mine.

This method of finding is available in the "Friends of Military and Civilian Talents".

Don't think about what this wave is called!

Looking at the barrage, Ningbei wrote down the means of removing impurities from coal and the treatment of honeycomb coal.

After a moment's thought, he wrote down how to make matches.

Fire means a lot to humans!

If it is said that words have brought mankind into civilized society.

Then the appearance of fire is for the ape-man to learn to use tools and gradually become a man.

Humanity has recognized and mastered fire, which has strengthened its ability to fight cold climates.

Fire can grill food; Can be used to hunt and defend against wild beasts; Can be illuminated; It can dry wet objects and turn ice cubes into drinking water.

The great man said: "For the first time, friction and fire caused man to dominate a force of nature, and thus finally separated him from the animal kingdom." ”

In addition to the fires caused by thunder splitting trees, the first method of human beings to raise fires was to drill wood for fire.

Then the ancients discovered flint, also known as flint.

When two flints collide, a spark can be created.

But the probability of such a fire is not large, and the conditions are harsh.

As for the fire fold, that thing was still made in the Song Dynasty.

And the probability of fire folding is not large, these fire tools are all face-looking.

Those with black faces may not be able to take out Mars every time.

Therefore, Ningbei still wants to make matches, or in one step!

Take out a match, swipe it lightly on the matchbox, and the fire will come.

Although matches are not guaranteed to catch fire, they are far more convenient than other fire raising tools!

That's enough!

Ningbei believes that as long as he makes matches, it will be a big hit in the Tang Dynasty!

And matches are also consumables, and they are also close to the people with large quantities and thin profits!

Hiss...... In fact, in the early stage, it is not very close to the people, and it is okay to pit the rich man first...... Ahem, I'll talk about it when I travel back to the Tang Dynasty......

As for lighters, although it is more convenient, knowing that this thing also requires butane and plastic.

This manufacturing process is a little complicated, so I won't do it for the time being.

Start by making matches.

After talking about firewood, it's time to talk about rice.

Rice is rice, and this has been said by a steady stream of viewers since the first day of his live broadcast.

Ningbei also considered carrying more conventional rice, after all, this thing is not something that can be cultivated in a short period of time.

Let's take some experimental fields with you first!

There are some things that can't be cultivated in a short period of time.

Then he can only carry it with him.

But who would have thought that when chatting about rice, the audience in the live broadcast room argued again.

As we all know, the environment in the south and the north are not the same, which leads to the different habits of the north and the south.

Especially the difference in diet between the north and the south, the battle between sweet and salty tofu brains has been going on for a long time, but these are not the point.

This time, it was rice and noodles that made them quarrel.

Generally speaking, audiences in the south prefer to eat rice, while audiences in the north tend to eat noodles.

And rice and noodles are, to put it bluntly, rice and wheat.

It's hard to reconcile, and it's normal for both sides to like it.

Moreover, the yield of these two staple foods is not low, and the yield of any seed can be increased several times in ancient times.

Therefore, both staple foods can feed the people of ancient times, and they are both foods that can save people.

But it is precisely because of this that the two staple foods are almost the same, which also leads to a sudden change in the style of barrage painting in the live broadcast room.

"Why firewood, rice, oil, salt, sauce, vinegar tea? Isn't chai, wheat, oil, salt, sauce, vinegar tea? The pasta is delicious, too! ”

"What the ancestors handed down is firewood, rice, oil, salt, sauce, vinegar and tea, you have the ability to ask the ancestors!"

"I think rice is easier to make than pasta, just boil or steam, and wheat has to be processed."

"Is pasta a good fill? It won't take long for you to get hungry when you eat rice, and you won't eat pasta! Brother Bei traveled to ancient times, if you want the people to be full, you have to plant wheat! ”

"Wheat has to be crushed into flour to make flour, but the ancient people couldn't even eat rice, so how could they have the strength to grind flour? Brother Bei still grows rice. ”

“……”

Seeing the audience chattering about which rice or noodles was better, Ning Bei couldn't cry or laugh.

He was about to say that the two staple foods could be planted together, but the barrage had already given what he wanted to say.

"What the hell, what do you want to do so much? I want both staple foods! Seed them all! ”

"The main thing is that there is not enough arable land! The current fertile land may still be wasteland in ancient times, and it can't be used, how can you grow food? ”

"The arable land is fixed, and the grain production is the only one. But the Tang Dynasty didn't fight much, and the number of people would only increase, so what to do when the population exceeded the grain production? ”

"Not to mention anything else, the people in the remote areas of ancient times couldn't eat and became disaster victims, and these people were all mouths waiting to be fed! How can you feed them? ”

"We still have to reclaim the wasteland, and find out about the curved plough and the cylinder car."

"Damn, the anchor just doesn't want to listen to me, let's unify the blue star directly, and I'm afraid that there will be no food to eat?"

"Potatoes, corn, sweet potatoes...... Which of these things is not a high-yield batch? And it can be eaten as a staple food, and the Qing Dynasty relied on these vegetables to feed hundreds of millions of people, and it was finished! ”

"It's still the same sentence, as long as Brother Bei can unify the Blue Star, you will have everything to eat and drink."

Ningbei: "......"

Isn't it endless?

How did you go around and around to the unified blue star?
