Daqin: Zulong's Traveling Frog

Chapter 43
[Ding, the little boy brought special products, please check them! 】

Qin Wangzheng clicked on the system panel, and saw a black mass, the size of two fists.

Qin Wangzheng leaned forward to watch curiously, and gently touched it with his hand.

Unexpectedly, the fingers were dyed black.

"What is this?"

Qin Wangzheng observed it carefully, and said, "Could it be a stone?"

thump.
thump.
While he was talking, Xiao Zhinu rode into the heavy snow and stepped into Xianyang Palace.

The little childish slave stepped forward and picked up a dark, stone-like black object, which was coal.

To be precise, it is a pinch of stone!

The popularity of coal needs to be after the Song Dynasty.

Now China uses charcoal, but charcoal is expensive and only nobles can use it.

The charcoal burned in the main hall of Zhangtai Palace was used to keep Qin Wangzheng warm.

Qin Wangzheng thought it was charcoal, but who knew it was coal, which was a bit disappointing.

Coal does not burn as well as charcoal.

And the burning of coal will produce billowing thick smoke, which can be fatal.

but
It is more considerate for the little childish slave to bring it.

In fact, Xiao Zhinu brought coal to solve this problem.

Because coal is so seldom used, coal ore piles up in the mines.

When the little childish slave passed by the mine, he felt that it was a pity to waste it.

I brought it with me.

The reason why coal has not been used is because this era has not yet mastered the appropriate combustion method.

The biggest difference between coal and charcoal is that coal has a higher density and more magazines!

Therefore, compared with charcoal, pure natural coal does not burn particularly well.

More importantly, coal combustion may also be extinguished due to uneven heating.

But if honeycomb
That's different!
Briquettes were used for nearly 2000 years, and were not abolished until the popularity of natural gas.

The appearance of briquette is of course needless to go into details. The densely packed holes on it are to increase the contact area with the air, so that the coal can be fully burned.

What's more, briquette is easy to make, very simple, nothing more than increasing the contact area with the air to achieve the effect of flame retardancy.

Although honeycomb is useless except for heating, it cannot be used for smelting.

But in this winter where the university is flying
Using honeycomb briquettes for heating is much better than charcoal.

then
Xiao Zhinu took out the dagger in the system.

Insert a few holes in the stone-like coal to make a rough briquette.

Little children can be gods, but they can't be too gods.

I can only think of rough things. As for practice and improvement, it is natural to rely on Qin Wangzheng.

Qin Wangzheng became more and more curious when he saw Xiao Zhinu stabbing deep into the coal with a knife.

then
Qin Wangzheng also ordered people to take out short knives, and Mingxi followed Xiao Zhinu to poke coal.

Xi was stunned and didn't know the reason. He thought it was the childish slaves who were destroying the coal and wasting natural resources.

But Xi didn't dare to say a bad word about Xiaozhinu, but said indifferently: "It seems to be another whimsical idea of ​​Xiaozhinu!"

Qin Wangzheng watched as the two men poked a deep hole in the coal.

I even want to experience it myself.

But because of face, Qin Wangzheng did not leave for a long time, just fantasizing about poking coal with the little childish slave in his head.

As time passed, Xiao Zhinu's work was almost completed, and then he hurriedly asked Xi to stop.

then
Xiao Zhinu picked up the briquettes in his hands and quietly walked to Qin Wangzheng's feet.

Qin Wangzheng bent down and looked at the dark-complexioned young slave, with a faint smile on his lips.

"Come here! Clean the little childish slave!"

Qin Wangzheng glanced at Xi, who was also dark-skinned, but there was a hint of evil spirit in his eyes, and he scolded: "Hurry up!"

In desperation, Xi could only bow his knees and leave with his head down, to go to the bronze Yunlong altar where the little child slave was prepared to take a bath.

hi clearly remember
When Xixi just took office, he received an order from Qin Wangzheng to find the bronze Yunlong altar, just to bathe the little childish slave.

History is always strikingly similar.

Xi once again brought the bronze Yunlong altar to Xiaozhinu.

But today is different, Xi already knows that Xiaozhinu is a divine beast, and serving it a jar also has a sense of mission.

Qin Wangzheng picked up the dark-skinned young slave.
Not even a little bit disgusted.

On the contrary, I think the little childish slave is a bit lively and cute.

Even if it was black-handed, Qin Wangzheng didn't care.

After a lot of anticipation and anticipation, the little childish slave finally came.

It's too late for Qin Wangzheng to be happy!

The little childish slave seemed to be in high spirits, and held up the briquettes high.

Although picking up a knife to poke, the resulting shape is somewhat distorted, and some have even cracked.

But it doesn't matter what shape it is, as long as it can be used!
Qin Wangzheng was a little surprised, could this briquette be burned?
But seeing the satisfied smile on the little child slave's face, Qin Wangzheng also smiled happily.

but
The appearance of briquette is epoch-making.

It means that the expensive charcoal that has been used for hundreds of years will slowly be replaced by cheap coal.

This is the special product that Xiao Zhinu wants to bring to Qin Wangzheng.

this specialty
Although it cannot expand food and grass like winter wheat, it can help ordinary people survive the winter smoothly.

After all this thing.
Compared with the cost of charcoal, it is still easy for the common people to accept.

Qin Wangzheng was a little curious when he saw the little childish slave holding coal.

at last
Xi smiled and brought the little child a water jar for bathing!

Seeing the little childish slave jumping around with the briquettes, a smile appeared on the corner of Xi's mouth.

Seeing Xixi serving the water altar, Qin Wangzheng put his hand on the edge of the water altar.

The little childish slave also tactfully jumped into the water basin and rinsed himself.

As for charcoal, it fell into the hands of Qin Wangzheng.

Qin Wangzheng looked at the coal with many pores in doubt, and asked himself: "Can this coal really burn?"

Xi Tian really thought she was asking herself, so she replied: "Maybe!"

Qin Wangzheng glanced at Xi, his eyes were sharp, like a sharp knife, piercing deeply between Xi's eyebrows.

Xi couldn't bear the strong sense of oppression, and lowered her head obediently, but her hair was already wet with cold sweat.

Qin Wangzheng said coldly: "Then replace the coal, the lonely king will see how it works!"

Xi swallowed, and tremblingly took the coal.

It stands to reason that coal does not burn as well as charcoal, and it burns vigorously.

What's more, coal emits dense smoke.

Smoke can even kill you.

but
After being poked with a knife by the little childish slave, it's not easy to say.

Xiaozhinu is a divine beast, and all civil and military officials in the court can see it for all to see.

Even the nonsense of a childish slave will not harm Qin Wangzheng.

In case, the combustion effect of this kind of coal is good?

Under the watchful eyes of everyone, the coal was ignited by Xi.

There are no lighters in this era, only flints can be used.

And coal naturally needs to be ignited with charcoal, otherwise the combustion will not be complete
Naturally, the ignited coal could not just be placed in the temple like this, but placed on a huge rock.

Qin Wangzheng was also watching this scene quietly.

I don't know if Xiao Zhinu's actions can bring blessings to Daqin again?
The fire on the coals is small, but even, which means the coals won't go out.

Qin Wangzheng stared in amazement at the ignited coal, which burned more and more prosperously.
