After heavy snowfall, the road is even more difficult to walk….
It’s wet, muddy, but slippery in some places!
All the way….
It wasn’t a very long way to walk for half a day to return to the palace!
Zhao Che, whose face was black and red, was overwhelmed by the First Emperor before he could go to bathe and change clothes!
“How did Aye’s little slave become like this?”
I miss it all day and miss it so much!
Zhao Che did not return overnight, and today he saw his good grandson returning, and the first emperor was very close.
Regardless of Zhao Che’s dirty body, he hugged Zhao Che into his arms.
Qian on the side also smiled when he looked at the warm scene in front of him, how long had he not seen such a heartfelt smile from his own king?
Zhao Che was lying in the arms of the First Emperor, wiping the First Emperor’s dragon robe with his little black hands everywhere, while Qian was telling what happened when Zhao Che went to Xiaye!
Talking about Zhao Che playing briquettes with the group of children, he also talked about Zhao Che sleeping on a hard wooden bed in his arms….
“My little slave has done another terrible thing!” After listening to Qian’s narration, the First Emperor smiled!
This group of veterans in Xia Ye has always been the heart disease of the First Emperor!
It’s just that they have always been unwilling to accept the reward of the First Emperor!
But Zhao Che used a child’s almost playful way to find them a livelihood to subsidize the family!
This makes and sells briquettes, which will not be rich, but it can also improve their lives so that their lives are not so embarrassing!
Moreover, the low cost of briquettes can also be used by ordinary people throughout the winter!
This year’s cold winter, it seems that with the arrival of Zhao Che, it is no longer cold!
Although life in Guanzhong is much better now, there is still no shortage of people who freeze to death every year, and there are always a few who can’t collect enough firewood and can’t burn charcoal….
But Shi Ne, everywhere!
This kind of stuff is all too common… In the Qin Dynasty, where coal mines were not widely used, coal open-pit bonanza could be described as everywhere!
“The little slave is amazing! Tell Aye how the little slave came up with it? The First Emperor smiled and pinched Zhao Che’s nose!
“It’s a win! Katsu told me that if the wind can’t go in, Shi Nei can’t burn up! I thought, if you make Shi Nei empty, won’t the wind be able to enter? Zhao Che replied with wide eyes!
Listening to Zhao Che’s childlike but natural tone, the First Emperor was speechless for a while!
“Your Majesty! The minister thought that this stone neath was the same as making a fire, and it was not good to have more firewood, so he picked up the firewood, took a fan and fanned it a few times, and this wind went in, and the firewood could burn up! Qian added with a smile on the side!
“Isn’t Xiaogongzi’s move similar to making a fire?”
The First Emperor nodded and looked at Zhao Che with a little strangeness!
Oh, yes!
It’s so simple….
Everyone will make a fire to cook….
But why can’t everyone think about it?
Zhao Che was stunned for a moment, Qian was actually right, the principle of the essence of honeycomb coal is no different from making a fire!
Anyone who has ever made a fire knows that if you add too much wood at once, the fire will be extinguished!
This is because the wood accumulates, so that the contact area between wood and oxygen is not enough!
Therefore, when making a fire, the firewood should be loose and scattered, so that oxygen can fully contact with the firewood!
This is also the principle of briquettes!
The density of formed coal raw ore is too large, unlike the loose structure of charcoal!
Therefore, it is necessary to artificially break the coal, mix it with the soil, and make it into a dense honeycomb shape, which is equivalent to artificially increasing the contact area between coal and air!
So that the coal can be fully burned!
Both of these principles are essentially the application principles of oxygen and fuel!
After listening to Qian’s words, the First Emperor suddenly became cheerful!
This is really the truth, isn’t this the same as making a fire!
But his mother’s beauty is wonderful!
The First Emperor himself also made fires!
How many tens of millions of people have ever had a fire in this world?
“Have you ever made a fire?” The First Emperor smiled and looked at Qian.
Qian nodded silently….
“Xu also made a fire, when he was a child, he was exhausted, and he even made a fire to make rice…” The First Emperor shook his head!
“The last time I was thinking… There are so many people who have been torn by fish hooks under this day, how can a little slave find the key? ”
“How can there be tens of millions of people who have made fires under the sun… But it was also a little slave who discovered the key! The First Emperor’s tone was not without emotion!
But it’s not surprising, it’s not scary!
This is the benefit of Zhao Che’s deliberate control of his performance!
The Quyuan plough and honeycomb coal he made are all out of life, and they can be traced back to the roots!
And its essence is ridiculously simple!
Of course, the First Emperor would not think much about it!
“The world often says that those who are born to know, in the eyes of Xuan, are not as good as childish slaves!” The First Emperor looked at the little childish slave with a dark face and smiled!
“You little fellow…” The First Emperor and Qian looked at each other speechlessly, revealing a helpless smile!
This person is indeed different from each other, simple to thorough truth, can only be used by Zhao Che, this kid!
