In the fifth year of Zhenguan, on the fifteenth day of the twelfth lunar month, at the end of Sishi, we were in Qin Mansion, Lantian County.
Qin Ming had a very fulfilling life in the past ten days. After breakfast every day, he went to teach the children in the academy. After class, he went to the medical school to discuss some modern medical knowledge with Daozhang Sun.
Both of them benefited a lot from the process. Some of Qin Ming's modern theoretical knowledge, such as disinfection, bandaging, hygiene, and some Western surgical therapies and operations also gave Sun Simiao a deeper understanding of medicine.
Qin Ming has also become Sun Simiao's best friend, and now their titles have gradually become
"Dean Sun"
"Principal Qin"
After lunch, Qin Ming will dive into the research institute and study paper and cement with the craftsmen.
Of course, in addition to this, Qin Ming thought that the Chinese New Year was approaching, so he found a few craftsmen and took out some gunpowder with a slightly different proportion and less power, and asked them to study and make fireworks.
This was Qin Ming's first year in the Tang Dynasty, and he still wanted to live a special life, at least with a touch of future generations.
After more than ten days of repeated experiments, the papermaking process has now been almost perfected. Not only soft white paper has been created, but also toilet paper.
Just wait until the New Year is over to build a workshop and start large-scale production.
The cement on the other side has also been developed, and after experiments, the effect is similar to that of later generations of cement.
On the day the experiment was successful, Li Chun was so excited that he cried, but soon Li Chun threw another problem to Qin Ming.
After calculation, although cement is good, the cost is too high if it is fired by firewood, and it is too luxurious to use for paving roads.
So Qin Ming thought of coal as a fuel. In the Tang Dynasty, some people actually began to use coal for heating, but the scope of use and the number of people were relatively small.
The reasons are very simple. First, burning coal will produce a large amount of harmful gases. Long-term use of coal for heating can easily lead to illness or even death. Second, coal is generally difficult to mine on a large scale in mountains.
But these two problems are easy to solve for Qin Ming. The toxic gas can be discharged through the chimney. As for mining coal, he can use explosives to secretly blow up the mountain.
The only troublesome thing was looking for coal mines, so in the past two days he arranged for his guards to go around to find out where there were coal mines.
It wasn't until yesterday when Cheng Chumo came to the house to pick up soap that things turned around.
According to Cheng Chumo, he knew where to find the coal mine, so Qin Ming and Cheng Chumo made an appointment to go to the coal mine together today to have a look. If it was really a coal mine, Qin Ming was prepared to buy it regardless of the cost.
This is also the reason why Qin Ming did not follow Yang Zijun to Chang'an City today.
Qin Ming finished lecturing the children early in the morning and waited for Cheng Chumo to come over.
Waiting until the end of Si Shi, Cheng Chumo finally came to the Qin Mansion with a group of guards.
The two of them exchanged a few pleasantries, then took their guards and headed towards the outside of the village.
Because they did not bring any female relatives with them on this trip, Qin Ming and his party all rode horses. After walking for more than half an hour, they finally arrived at their destination.
Cheng Chumo pointed to the mountain in front of the two of them and said:
"Brother Qin, look at that mountain. That's where I saw the poisonous carbon last time."
Qin Ming looked in the direction Cheng Chumo pointed. Among the large mountains, only the mountains in the direction Cheng Chumo pointed were bare with a few trees growing on them, which was particularly obvious.
I think there should be coal mines in these mountains.
"Let's go and take a closer look."
After saying that, Qin Ming rode towards the foot of the mountain. Cheng Chumo, Qin Da and others saw this and followed Qin Ming to the foot of the mountain.
Qin Ming led a group of people around several mountains and finally stopped somewhere with a landslide.
He dismounted and walked closer, looking at the dark cliff, he couldn't help but laugh.
Cheng Chumo saw this and asked:
"Brother Qin, are you okay? It's just poisonous carbon. Are you so happy? I heard that this thing is only used by the poor, and it can poison people to death if you are not careful."
Qin Ming suppressed his smile, looked at the coal mountain in front of him, then pulled Cheng Chu and said silently:
"If I said I had a way to stop the poisonous gas produced by these toxic carbons from harming people, would you believe it?"
Cheng Chumo's eyes widened when he heard this, and he reached out excitedly to grab Qin Ming's hand and said:
"Brother Qin, do you really mean what you say?"
"My brother, why am I lying to you? Let's first find out if there is an owner of this mountain. If not, our two families will buy him out as a partnership. How about recruiting workers to open the mine and build a workshop later?"
Cheng Chumo heard this and patted Qin Ming's shoulder and said:
"Good brothers, you are indeed my beloved relatives, friends, brothers, let's go to the Lantian County Government Office and ask."
As he said this, he pulled Qin Ming onto his horse, and the group headed towards the Lantian County Government Office.
About an hour later, Cheng Chumo came out from the door of the government office.
Qin Ming, who was at the gate of the government office, hurriedly stepped forward and asked:
"How's it going? Is there any result?"
Cheng Chumo pulled Qin Ming to the side of the road, sighed and said:
"Hey, there's some trouble. That mountain belongs to the Changsun family."
Qin Ming didn't react for a moment after hearing this, so he asked:
"Which eldest grandson's family?"
"Who else is the eldest grandson of the family? The uncle of the current dynasty, the eldest grandson of Zhao Guogong, is Sun Wuji. Have you forgotten that we know each other because of the eldest grandson Huan?"
Qin Ming realized it at this time. It turned out to be him. It was too long ago. Qin Ming only remembered that in the film and television drama, Changsun Wuji seemed to be exiled by Wu Zetian in the end, and then committed suicide.
Changsun Wuji's ending has nothing to do with him. However, Qin Ming still remembers Zhang Sun Huan, and it makes his teeth itch when he thinks about it now.
Since it belonged to Changsun Huan's family, he had to buy it no matter what.
He looked at Cheng Chumo and said:
"Then what do you think? Don't you want to buy it?"
Cheng Chumo's eyes widened when he heard this, he patted Qin Ming and said:
"Brother Qin, what are you thinking? I will definitely buy it. When I get back home, I will tell my father that he will definitely have a way to buy it."
Qin Ming nodded when he heard this. It was indeed difficult for him to discuss this matter with the eldest son's family due to his status. He thought for a while and said:
"Okay, I'll write a letter later and give it to Uncle Cheng when you get back."
