"The snake liquid is poisonous and can also be used as medicine. Although it is a tragedy for those who die by burning coal, it is just a tragedy."

As a time traveler, He Jin certainly knew that burning coal would cause carbon dioxide poisoning. But to say that it is not right, he really... is a little grateful for this.

Because if this was not the case, he would not have found such a huge business opportunity.

There is no doubt that our hardworking and intelligent Chinese nation is the earliest nation in the world to use coal. As early as the "Shan Hai Jing" and "Shan Shan Jing" of the pre-Qin period, there were records of coal.

From the Western Han Dynasty to the Wei, Jin, Southern and Northern Dynasties, coal wells and coal mining operations of a certain scale appeared. Not only did they start to use raw coal to make iron, but they also molded and processed pulverized coal into coal cakes.

During the Sui and Tang Dynasties, coal development was further developed, and its uses were expanded to metallurgy, ceramics, and of course, there was also an alchemy business with great Chinese characteristics.

Even in the Song Dynasty, coal coking earth kilns appeared.

But in He Jin's era, during the Little Ice Age and the climate was extremely cold, he found that coal was not used for heating around him.

Rich people like Shen Xiuer use expensive charcoal, while poor people... can only harvest firewood, well, just like He Jin.

Has history gone backward?

Of course not.

The reason for this is that the ancients always had a slight understanding of coal.

He Jin guessed the reason. Perhaps the coal used by the ancients to smelter should have been used to choose smoke-free raw coal of good quality.

Although anthracite has a high ignition point, it can contain extremely low sulfur content, and it is colorless and smokeless when burned, and it lasts for a long time. As long as the air is kept unobstructed, people will not be poisoned and killed.

Ordinary raw coal has not been cleaned and will evaporate a lot of fatal gases such as sulfur dioxide and carbon dioxide when burned, which will lead to poisoning and death.

Ordinary people do not have the professional knowledge of coal preparation, so they will naturally have the impression of being afraid of coal, and will not apply it on a large scale to keep warm.

"Does He Guanren know the correct way to use coal?" Shen Xiuer looked at He Jin half-believingly, feeling that this young man was too mysterious and incredible.

"Of course I know." He Jin looked at Shen Xiu'er, smiled slightly, and a beautiful curve appeared on the corner of his mouth: "Otherwise, how dare I use this as a business?"

Of course, he did not want to carry out coal washing and desulfurization processes in the era when industries such as the Ming Dynasty had not yet begun. Instead, he knew that there was a good-quality anthracite mine in Cizhou - Fengfeng Mine Area.

Looking around the whole country, Fengfeng Mine Area may not be considered a famous coal mine. But for He Jin at this time, it was simply a gold mine waiting for him to catch!

Shallow coal mines are easy to mine; the amount of 3.5 billion tons of mineral deposits is almost inexhaustible and inexhaustible; the smokeless raw coal produced is better than expensive charcoal in terms of cost-effectiveness, and more than ten times the burning firewood for a short time.

Finally, the kangs are equipped with chimney flues, and the buildings of this era still do not meet the sealing standards.

Therefore, even if the burning anthracite will evaporate some toxic gases, most of them can run out along the chimney, and the rest will be exchanged and dissipated with the air, which will almost cause no harm to the human body.

Based on the above, as long as you take down the Gushan vein in Fengfeng Mine Area, it is basically equivalent to doing a business without a foundation, and it is difficult not to get rich!

Thinking of this, He Jin could no longer suppress his excited expression, and then grabbed Shen Xiu'er's little hand by chance, and said with tears in his eyes: "The most important thing is that from now on, I can finally get rid of the fate of being a child laborer to chop firewood when I come back from get off work every day!"

Yes... If I hadn't abused He Jin like this, he wouldn't have thought of the perfect match between kang and anthracite.

After hearing all the explanations of He Jin, Shen Xiu'er even held her breath and her body was so soft that she couldn't stand: As the daughter of a merchant, she could see more of what huge amount of wealth the cooperation proposed by He Jin would bring! - This sudden sense of happiness really made her a little dizzy!

At this time, let alone He Jin shaking her little hand, even if she kissed her, she would only feel like she was falling into a dream.

The two of them held hands, standing in front of a pile of firewood, their eyes blurred and they didn't know where to belong.

When I saw this scene, I couldn't help but be surprised: Good boy, I didn't expect that the method of picking up girls was so superb! In just a short time... I've already held hands?

At this moment, I deeply hated that the noise was a little loud when I came back. The two of them looked back at the same time and immediately reacted, and their hands shrank back like they were electrocuted.

The next moment, He Jin couldn't help feeling a little lost: I didn't feel anything when I held it, but after I separated, I felt... Shen Xiu'er's little hand was really smooth.

Of course, Shen Xiuer was ashamed and annoyed, but the huge surprise was filled with emotions, which made her unable to think calmly, so she had to blush and explain: "He Guanren, it's important. The little woman must first conduct a field investigation. When she comes again next day, she will definitely give an explanation to the official!"

After saying this, she suddenly saw Cui's gaze and became even more surprised and excited: What explanation should I give... This is not a private lifelong decision!

But if she wanted to say something, she was afraid that the more she explained, the more she misunderstood. She was so ashamed that she turned around and pulled Yue'er, and ran out in a flash.

When he was about to go out, he couldn't help but say something in a strange way: "He Guanren, the little woman will be back soon!"

At this moment, He Jin couldn't help but giggle.

But before the laughter was blooming, a broom bump hit the back of the head: "What are you doing while standing there? Why don't you go back to your conversation!"

What words should I reply?...

He Jin was confused, but my mother was angry that she did not fight and raised her hand and threatened her with a broom.

Due to my mother's masturbation, he could only walk to the gate of the yard, and after a long time he said, "Oh, then you can go, welcome to come again next time."

I was so angry that I started to twist the soft flesh on He Jin's waist: "You are such a lump, I really don't know how you held someone's little hand just now. I'm so angry!"

Of course He Jin knew that I had misunderstood, but what could he explain?

Moreover, when he was thinking about the plan to make money, he really didn't care much. But now looking at Shen Xiu'er's graceful back, he suddenly felt aroused in his heart and had an inexplicable impulse: If he married Shen Xiu'er home, it would seem good...

First of all, this girl has a beautiful and smooth body and looks first-class.

Moreover, through several exchanges, it was also obvious that Shen Xiuer was smart. In addition, men were superior to women in the Ming Dynasty. Even if they were white, rich and beautiful, they would not be arrogant and domineering after marrying a wife, but would only obey and have three virtues.

The most important thing is that the two have the same views: they are all determined to make money!

These three views are the same, and it is difficult to achieve in the past life of free love. In the Ming Dynasty, when parents' orders and matchmakers' words, being able to marry such a wife who suits her heart is similar to winning the big prize by buying a lottery ticket.

So after turning around, He Jin suddenly showed a dementia again, scratched his head and said to me: "Mom, I seem to want to fall in love..."

I was stunned for a moment, then let go of He Jin's hand, patted his shoulder, and said with relief: "Well, the pigs that have been raised for fourteen years have finally known to eat cabbage... Although some toads want to eat swan meat, toads must also have ideals."

But just as the mother and son returned to the house and were having dinner and talking about how to get Shen Xiuer, suddenly, the gate of the courtyard was pushed open directly.

The mother and son looked back and couldn't help but be overjoyed: Hey, just said they wanted to pursue it, so they took the initiative to deliver it to the door?

Of course, Shen Xiuer and Xiao Yueer were still there, but soon, He Jin's face became solemn.

Because Shen Xiuer looked angry at this time, but said in a stern tone: "He Guanren, our coal business cooperation may be delayed for a while."

“Why?”

"Just just returned to the Shen family, the butler Fu told the yamen that Captain Hu from the yamen came drunk. He didn't say anything about the Shen family's goods, but also threatened the Shen family to give him 30% of the profits of the kang business! Otherwise, he would not be able to continue the kang business in Cizhou!"

"Hu Bugui, the headmaster of the fast-paced team?" He Jin couldn't help but frowned and said, "Didn't Uncle Fu tell him that I am protecting this kang business?"

"Of course I'll tell you." Shen Xiu'er's face was even more solemn and she said angrily: "But he said... You are just a lucky official who has left. This time he came to look for the Shen family, and he wanted to beat the dog to show the owner!"

"Oh?..." He Jin couldn't help but raise his eyebrows when he heard this. Not only was he not angry, but he sneered: "This is clear, I won't give me face... I'm just worried that I don't know who should use to establish my authority. He is so good that he has come to the door on his own initiative!"
