Back at the house, Qin Ming washed up, changed his clothes, and went to greet Li Yuan as usual.
As a result, as soon as he entered Li Yuan's courtyard, he saw the old man walking out of his house with a pair of big dark circles under his eyes.
When Qin Ming saw it, he stepped forward worriedly and stretched out his hand to help Li Yuan.
When Li Yuan saw this, he waved his hand towards Qin Ming angrily and said:
"What's that look in your kid's eyes? Do you think I'm too old?"
When Qin Ming heard this, he quickly took back his hand, saying to himself that you, an old man, don't know how to control yourself even at your age.
Forget it if you do this for one day occasionally. You have had dark circles under your eyes eight out of ten days. Can I not worry about it?
With this thought in his mind, he replied firmly:
"Grandson, I definitely didn't mean that. I just saw that the dark circles under your eyes are heavier today, and I'm worried that you didn't sleep well."
Li Yuan nodded after hearing this, coughed, and said calmly:
"Grandpa returned to the yard yesterday, so he was alone in the house, wondering how you made the fireworks last night. He kept thinking about it until he went to bed very late, so don't think wrongly."
Just as Qin Ming was about to answer, he heard the door behind Li Yuan being pushed open with a creak. Qin Ming looked up and saw Zhang Meiniang walking out of Li Yuan's room with a radiant face. When she saw Qin Ming coming, she smiled and said to Qin Ming:
"Brother Ming, it's good morning."
Without waiting, Qin Ming replied and floated past the two of them.
Li Yuan "...."
Qin Ming "...."
Afraid that the air would suddenly become quiet, Qin Ming was silent for a long time before coughing and then said:
"Since grandpa wants to know how fireworks are made, why don't you finish your breakfast later and let your grandson take you to see them?"
Li Yuan's eyes lit up when he heard this. Although he did not think about how fireworks were made last night, it did not mean that he was not interested in making fireworks.
He pulled Qin Ming and walked out of the yard, saying as he walked:
"Then what are you waiting for? Let's go and have dinner quickly."
Qin Ming took two quick steps to catch up with Li Yuan. These days, he has regarded Li Yuan as his only relative in the world.
Thinking of Li Yuan's dark circles, he was still a little worried. After thinking about it, he pulled Li Yuan's sleeve and said:
"Grandpa, there are some medicinal herbs in my grandson's house that are hundreds of years old. The chicken soup made from them is very beneficial to the body. Would you like my grandson to arrange for a servant to make you a bowl every day?"
Li Yuan was overjoyed when he heard this. These days, he has gotten to know Qin Ming very well. He knows that Qin Ming is not a person who is aimless. He also knows that Qin Ming often discussed medical skills with Master Miaoying in the past few days.
Since he said there are medicinal materials that are more than a hundred years old, there must be some. But when he saw from the corner of his eye, Qin Ming was looking at him with strange eyes.
He quickly stopped smiling and said seriously:
"I don't really care whether I can replenish my body or not. My grandfather's body and bones are in good shape. The main thing is your filial piety, grandson, which I can't live up to."
When Qin Ming heard this, the corners of his mouth twitched, and then he smiled and said to Li Yuan:
"Okay, then my grandson will arrange for a servant to make you a bowl of ginseng soup every night and send it over."
.....
After breakfast, Qin Ming took Li Yuan to the research institute. Also accompanying them were Xiao Qingwan and Yang Zijun.
They both heard at breakfast that Qin Ming was going to take Li Yuan to see how fireworks were made, so the two of them pestered Qin Ming and followed him to the research institute.
The craftsmen in the mansion were all bought by Qin Ming from Chang'an, so they basically live and eat in the institute now.
When the craftsmen in the institute saw Qin Ming coming to the yard, they all greeted Qin Ming with smiles on their faces.
Qin Ming also introduced Li Yuan to these craftsmen.
Seeing that Qin Ming could actually name all the craftsmen here, Li Yuan couldn't help but asked curiously:
"Boy, do you come here often? Why are you so familiar with these craftsmen?"
Qin Ming naturally understood Li Yuan's doubts and was worried that Li Yuan would look down on craftsmen like others, so he explained to Li Yuan:
"Grandpa, don't underestimate these craftsmen. Thanks to them, our house has been able to create so many industries in a short period of time."
As he spoke, Qin Ming pointed to a small courtyard built with red bricks in the institute and said:
"Grandpa, look at the red bricks used in that courtyard, which were developed by these craftsmen. They are beautiful and strong, and the cost is more than twice as low as the blue bricks."
After hearing this, Li Yuan looked in the direction Qin Ming pointed, and sure enough he saw a courtyard built with red bricks. There are also some unused red bricks piled next to the yard.
He walked forward quickly, reached out and picked up a red brick, weighed it in his hand, and then knocked on another brick. It was indeed very solid.
Upon seeing this, Qin Ming took the brick from Li Yuan's hand and put it back.
Li Yuan looked at the red brick courtyard, then at Qin Ming and said:
"Well, this red brick is really strong."
Xiao Qingwan jumped up to Li Yuan and said with a smile:
"Old man (this title was decided after Qin Ming and Li Yuan discussed it.) You don't know yet, but the new mansion will also be built with this kind of red brick in the future. When it is built, it will be very beautiful."
"And now many farmers in Zhuangzi who want to build houses next year have already bought such red bricks from the government."
Li Yuan smiled and nodded when he heard this.
Yang Zijun walked to Qin Ming, pulled his sleeve and asked:
"Sir, which yard is where the fireworks are made?"
Upon hearing this, Qin Ming pointed to a remote green brick courtyard in the distance and said:
"That's the courtyard, I'll take you there."
With that said, Qin Ming led a few people to the yard where the fireworks were made.
At this time, the craftsmen in the yard were all busy.
Seeing Qin Ming come in, they all stood up and saluted:
"Good morning, sir."
The leading craftsman Zhang Liulang stood up and asked:
"Young Master is here, but do you have something to arrange?"
Qin Mingchao waved his hands and said:
"It's okay. You guys are busy with your work. I just brought my grandfather here to take a look. We have worked hard recently. After today's work, everyone can rest."
Everyone cheered happily when they heard this.
Li Yuan had been looking back and forth in the yard since he came in. After a while, he discovered something unusual.
He patted Qin Ming on the shoulder, pointed at the busy craftsmen around, and asked:
"Boy, why do each of these craftsmen seem to do something different? Are they doing other things besides making fireworks?"
Qin Ming looked in the direction Li Yuan pointed and quickly understood what he meant.
He patiently explained to Li Yuan:
"There are several processes for making fireworks. In order to improve their work efficiency, a dedicated person will be assigned to do each process. In this way, it is much faster than one person completing all the processes. I divide this process into processes. The method of allocating craftsmen is called assembly line work.”
Li Yuan was shocked when he heard this. As the founding emperor, he still had some eyesight. After Qin Ming's introduction, he understood the subtleties of this assembly line operation.
If this method can be used in weapon manufacturing, it can also increase the speed of weapon manufacturing.
He really didn't know how Qin Ming's brain grew. He not only developed new things such as alcohol, soap, red bricks, mahjong, and fireworks, but also came up with such an effective production model.
Coupled with Qin and Ming's previous strategies to resettle the refugees, as well as the "New Arithmetic" he wrote, etc., Li Yuan even felt as if there was nothing in the world that he could not do.
At this moment, Li Yuan's idea of wanting Qin Ming to become the royal son-in-law became more determined. If the relationship between ancestors and grandchildren was put aside, Li Yuan would even want to marry his daughter to Qin Ming.
"That's not right. Qin Ming and I are not really grandparents to begin with. It's not impossible to marry a daughter."
Qin Ming probably couldn't have imagined that his grandfather, whom he regarded as his only relative in the world, was now thinking about whether to marry his daughter to him.
