Three Kingdoms start to kill Guan Yu

Chapter 800 Hua Xiong's Great Invention

Hearing Hua Xiong say that he has a way to deal with the poisonous gas produced by burning coal, Li Ru's eyes light up immediately.

If this thing can really be solved, then the fuel problem here in Guanzhong will definitely not be a problem.

It must be able to get a good solution.

After all, the charcoal is exactly the same as the stones under the ground.

It is said that a very small part can burn for a long time, even more than those solid wood.

"It's just...is this thing really so easy to solve?"

Hua Xiong nodded and said:
"It's really a good deal.

In fact, when you say that coal is poisonous, it is better to say that when it burns, it consumes some of the oxygen in the air.

We humans also need oxygen to breathe.

Burning coal consumes a lot of oxygen.

Under such circumstances, people's oxygen is not enough, and then they die.

In fact, it is not just coal burning that has this kind of problem.

It is normal firewood, as well as charcoal, which will cause this problem.

But relatively speaking, there are fewer problems with charcoal.

When using these things, as long as the room is not too closed and ventilated frequently, there is generally no major problem. "

Hearing Hua Xiong's words, Li Ru felt dizzy for a moment.

Again!
The lord is here again!
I started talking about these again, knowledge I didn't know, and terms I had never heard of.

As a smart man, he felt a little bit blind when the lord said something he didn't understand.

"My lord, what is this... this oxygen?

We don't all breathe the same thing.

Also, the wood doesn't burn all the time, so why does it have to burn the air? "

Li Ru, who always thought he was very smart, now only felt that his mind was full of question marks.

Hua Xiong said:
"It's different, although the breath we breathe is invisible and intangible, it is divided into many components.

A large part of it is oxygen.

What we inhale is oxygen, what we exhale is the air that we exhale.

Of course, the exhaled air is not purely exhaust gas, and there is also a part of oxygen that we cannot absorb.

Oxygen is a combustible gas.

Wood and the like burn, not just themselves.

Oxygen is also needed for combustion, otherwise it won't burn..."

Hua Xiong is here to popularize some common sense for Li Ru in future generations.

As a result, these later generations have become accustomed to knowledge, but Li Ru, a first-class smart person in this era, is in a fog.

Although he couldn't quite understand it, what did his master mean by what he said?However, Li Ru was still deeply shocked.

Hua Xiong saw that Li Ru was shocked by what he said, and couldn't help feeling secretly refreshed.

In other words, this feeling of bullying the ancients, especially the feeling of bullying a smart person like Li Ru, is still very good.

Next, Hua Xiong started experimenting.

Prove to Li Ruyong that what he said is correct.

He first found ordinary wood, put it into a closed room, burned it, and threw a few mice into it.

After a period of time like this, the closed room was opened, and the smell inside was choking.

Then I found that those coals were extinguished before they were completely burned, and the few alive and kicking mice were all dead. There were no wounds on their bodies, and they just died like that.

"See there is no Wen Xiansheng?
This is the oxygen in the room, almost consumed by the fire.

There is no oxygen in it, so the remaining firewood will not burn again.

It was precisely because there was no oxygen in the air that the mice were all suffocated to death. "

Hua Xiong pointed to the things in the room and explained to Li Ru.

Li Ru was shocked by what he heard, but at the same time couldn't help being a little worried.

"My lord...how about we go hide outside this room first?"

Hearing what Hua Xiong said, he looked at the few rats that died silently.

At this moment, Li Ru couldn't help holding his breath.

He looked like he didn't want to stay in this room any longer.

I am afraid that I will also step into the footsteps of this mouse.

Hua Xiong heard the words and said:
"Student Wen first needn't worry.

The door and window have been opened, and now there is oxygen in the room again.

Nothing will happen to us here.

However, the smoke from burning and the gas from burning coal are indeed harmful.

But as long as these things don't exist in a closed room, it's not a problem.

We can get a stove dedicated to burning coal.

Then get a pipe to connect to the stove to exhaust the burning smoke to the outside.

And prevent the wind from blowing the smoke and pouring it into the room.

When the coal stove is lit in the house, it should not be completely closed, so there will be no dead people.

The smoke is exhausted outside and will be diluted by a lot of air soon.

Basically, it will not have any impact on people and can be completely ignored.

Moreover, this coal is a good thing!
If it does burn, it will be hotter than some fuels like charcoal.

In the future, whether it is used as fuel or for smelting, it will be more useful. "

Hua Xiong gave Li Ru some popular science here.

At this time, Li Ru looked at Hua Xiong, completely changed the feeling that the students of later generations were taking physics and chemistry classes, and their eyes were opened.

This feeling made Hua Xiong feel secretly refreshed.

Through Hua Xiong's demonstration, Li Ru has understood a lot of things up to now.

Originally, he still had a lot of worries about the use of coal.

But now, with Hua Xiong's continuous explanations, and his own experiments to confirm.

The fear and worry about coal in his heart are also rapidly dispelling.

And in my heart, I began to look forward to my master being able to get out these practical things so as to make use of coal.

In this way, the fuel problem in Guanzhong can be completely solved.

More importantly, if coal is controlled and sold by the government, it can not only generate a considerable amount of income for the lord of his own family.

It can also create a lot of jobs, so that many people have something to do.

so that they can support their families.

Even live a better life than before.

This kind of thing can be said to be accomplished in one fell swoop.

Next, Hua Xiong started to make a coal stove.

While getting the coal stove, he also had some coal brought to him.

After a long period of exercise, and deliberate learning.

Hua Xiong's skills in drawing things have been greatly improved.

It's not as abstract as it was at the beginning.

Even he himself looked a bit big headed.

Now basically, I can draw fairly well.

People can see what he wants to express.

After drawing the coal stove, Hua Xiong quickly brought Ma Jun over.

Professional things should be handed over to professional people.

With Ma Jun, a top skilled craftsman, Hua Xiong was very relieved to hand over the coal stove to him.

The structure of the coal stove is very simple, not complicated.

After Ma Jun saw it, he said that he could make it very quickly.

For Ma Jun's craftsmanship, Hua Xiong can always maintain the greatest trust.

This is really a fairy-like character, always full of whimsical ideas.

Hands-on ability is also very strong, able to turn Hua Xiong's various ideas into reality.

And what he made was far better than Hua Xiong's blueprints on paper.

It's just that in just two days, a coal stove appeared in front of Hua Xiong.

The stove was so exquisitely built that Ma Jun even made an iron pipe to lead it outside.

After the coal was lit, the smoke was discharged out of the room along the iron pipe.

There is only heat left in the room, and there is no peculiar smell.

You can also adjust the speed of coal burning and the size of the flame by zooming in and out through the small hole on the lid under the coal stove

It can be said to be very practical.

But after Hua Xiong thought about it, he still didn't promote this thing immediately.

First of all, this kind of stove burns coal, which is too wasteful.

And it is inconvenient to use, and it is not easy to catch a flame.

So he thought about it and drew another tool.

This tool is something used to make briquettes.

When Hua Xiong was young, gas and natural gas were not promoted.

In many places, it is still coal.

Honeycomb coal is very common.

At home, I also made briquettes myself, so I am no stranger to this.

Hua Xiong drew the things and explained them to Ma Jun.

Ma Jun soon made the honeycomb tool and made it.

The next step is to make briquettes.

Crush the coal first, then add yellow mud, inject water and stir to increase the viscosity of the coal, which is convenient for the next shaping.

Hua Xiong couldn't remember the exact ratio of yellow mud to coal.

However, it only takes a few more experiments to master it.

After a few more days, the briquettes that have been punched out have been baked and can be placed in the stove for burning.

Hua Xiong put the briquettes into the adjusted stove again and ignited it.

After the flame burns up, put a pot on it and eat hot pot directly on it.

On a cold day, a few people gathered around the coal stove, eating hot pot in a warm room, not to mention how comfortable it was.

Ma Jun was full of praise for Hua Xiong's creation.

I think this coal stove is really easy to use and worth promoting.

But what Li Ru said next poured cold water on Hua Xiong, Ma Jun and others.

"My lord, this coal stove is good, but... the cost is too expensive.

How many ordinary families can afford it?

The current cost of the coal stove, plus the later purchase of briquettes.

They would rather burn less firewood than spend the money. "
