Chapter 37 Li Er: Little shopkeeper, how about we become sworn brothers?

Last night's rain left traces in the big canal outside the door. The water level rose overnight, and some places even flooded the road.

The area where Liquanfang and Xishi meet is the worst-hit area. When Li Shimin came, he stepped on it several times.

Water splashed and mud sprayed everywhere, even on his face.

But Li Shimin is laughing happier than anyone else now.

He was holding a huge bag in his hand, which looked very heavy.

"Old Li, I've been waiting for you for a long time."

Liu Xuan was reading a book behind the counter today. The ancient characters were a bit complicated, but after all, you can still understand them after getting used to it.

Hearing Li Shimin's voice, Liu Xuan got up.

But what Liu Xuan never expected was that Li Shimin actually came here with a sack on his back today.

The sack was placed on the ground, and Li Shimin opened the drawstring to reveal the black raw coal.

Liu Xuan immediately covered his mouth and nose.

This is raw coal. Don't you know about dust pollution?

"Little shopkeeper, I brought you the things, but is it the black gold you want?"

Liu Xuan nodded: "Yes, it is indeed this."

In the house in the backyard, in front of the stove, Liu Xuan took out the unwashed coal and threw it directly into the stove.

The firewood that was originally burning seemed to have suddenly lost its vitality at this moment, and was directly pressed down by the black coal blocks and could not raise its head.

Li Shimin poked his head and looked into the stove.

"When this thing burns, the smell is very strong and poisonous."

"So the stove must have a chimney and ventilation. At night and during the day, the door cannot be closed tightly and there must be a ventilation hole."

Li Shimin silently remembered it in his heart.

"Da Zhuang, have you finished washing?"

In the yard, Da Zhuang's voice came: "Master, it's so dirty."

"It's right to be dirty, wash it more."

Raw coal cleaning is a technical job. If most of the impurities are not washed away, it will not only affect the combustion efficiency, causing the coal blocks to not burn fully, and produce a large amount of carbon monoxide, but also cause people to be poisoned because of the release of toxic gases from the impurities.

No one wants to have a headache, chest tightness, shortness of breath and weakness for no reason, right?

The Tang people liked to put charcoal basins in the house, even so, they had to leave ventilation holes in the house.

During the Wude period, many people died of suffocation every year because of burning charcoal.

Not long after, the coal that Da Zhuang brought back was different. After washing, the coal blocks that looked large were a whole circle smaller.

"When black gold burns fully, the flame is invisible."

"Of course, Lao Li, you can call this thing coal."

"The reason why I call it black gold is that this thing is black gold."

The process of washing coal with water is relatively complicated. It is also full of difficulties to complete it completely in the Tang Dynasty.

The manpower and material resources consumed in this process are not what ordinary people can imagine.

The oldest fuel naturally chooses the most primitive cleaning method.

At this time, Li Shimin looked at the coal in Liu Xuan's hand, and then looked at what he brought back. It was indeed different.

The coal in Liu Xuan's hand was black and shiny. It was obviously black, but it seemed to be extremely dazzling. Could it be that this was the colorful... black?

"Look, what I threw in just now is almost burning. There are bursts of black smoke. The furnace must be turned off."

"Look at this again."

Liu Xuan directly threw the washed coal in his hand in, and a sizzling sound sounded in an instant. It was the water vapor evaporating rapidly.

After a moment, Li Shimin's eyes lit up.

This thing, when it burns, seems to be brighter and more transparent than the previous one that has not been washed.

Although the firewood in the stove is clean, the whole room is even hotter.

"Good stuff, good stuff!"

Li Shimin touched his beard excitedly, and kept moving his head towards the stove, not afraid of burning his beard.

"Little shopkeeper, I have handed this thing to the people above, and it will arrive in Tianting soon!"

"If it is really as the little shopkeeper said, it is not a problem to be promoted to an official position!"

Li Shimin began to act.

I should cooperate with your performance, I can't turn a blind eye.

"Congratulations, Lao Li, when the time comes, you will definitely be rewarded a lot by the superiors, don't be stingy, please have a meal!"

Li Shimin smiled awkwardly, does this mean that I have to pay more money?

After the autumn rain was dried by the sun that just came out, the ground was as bright as new, as if it had been washed once.

Li Shimin squatted in front of the stove and listened patiently to Liu Xuan's explanation of the drawings, which were coal washing things.

When he heard something he didn't understand, Li Shimin would ask patiently. As the king of the Tang Dynasty, he didn't think his face was that important.

A real man can bend and stretch, and he doesn't feel ashamed to ask questions. Confucius said it was good.

When he thought of Confucius, Li Shimin straightened his back. If coal could be popularized in the Tang Dynasty, then from now on, his name would definitely be as famous as the sages, right?

Thousands of years later, when people talk about me, Li Shimin, they will definitely respect me.

Hehe...

Li Shimin laughed unconsciously.

"Old Li, what are you laughing at?"

Li Shimin waved his hand: "Liu Xuan, do you have an incense burner at home?"

"Uh, no."

"Do you have incense and candles?"

"No?"

"What about the Guan Gong statue? You open a business, you should have a Guan Gong statue, right?"

In folk culture, Guan Gong is not only a martial god, but also a god of wealth, commonly known as the martial god of wealth.

People who open a business must worship Guan Gong, which means to get rid of evil and make money.

"Old Li, what are you doing?"

When Liu Xuan heard that Li Shimin wanted to find Guan Gong, and saw Li Shimin's arrogant look, he shuddered subconsciously.

This guy, is he trying to learn from the crow?

"Little shopkeeper, you and I are doing such a big thing together, which benefits the country and the people. Although we have only met a few times, you don't seem to care about fame and fortune at all. Li admires you very much."

"Today, you and I will become brothers with different surnames. We don't ask to be born on the same day of the same month of the same year, but we ask to die on the same day of the same month of the same year..."

Liu Xuan hurriedly pressed Li Shimin's mouth.

"No, no, no, how old are you? How old am I? I still have a long life ahead of me."

Li Shimin smiled embarrassedly: "No matter what, after today, you are my brother, good brother, don't worry, I will give you good news in two days!"

Li Shimin is as excited as a child now.

But Liu Xuan can understand.

If this matter is placed on Changsun Wuji, I am afraid that the old shady guy will not be calm, and he will not pretend to be a powerful person or to engage in power politics and favors.

That is a gift from nature.

There is no incense burner, no incense candles, no Guan Gong, only a big tree.

"I am Li Er."

"I am Liu Xuan."

"Today we are brothers, and we will never change in this life, and we will never change in life and death!"
