Du He saw Du Ruhui in the study, and saw that Du Ruhui was even more haggard than before.
He must be worried about his own affairs!
Du Ruhui raised his head and saw Du He. He didn't make any movement, but his eyes suddenly brightened a lot.
"He'er, are you back?"
"came back!"
In a simple conversation, Du He could feel Du Ruhui's unique fatherly concern for him.
Du Ruhui nodded: "It's good to come back. You need to be more careful when doing things in the future. Before, I would have educated you well. But now that you have grown up, Dad knows that you have your own ideas, so no matter what you do,
, Dad won’t blame you. He can even support you when necessary.”
Du He felt a little shocked.
To a certain extent, Du Ruhui's thoughts are more advanced than those of ninety-nine percent of people in this era.
The father and son chatted for a while and then went back to their rooms to rest.
Early the next morning.
Du He went to the furniture factory again and then entered the palace with the gold medal.
What he promised to the old man has not yet been fulfilled.
When we arrived at the lake in the east inner garden of the palace, to our surprise, the old man did not fish, but hid in a pavilion nearby to fight the landlord.
In addition to the old man, there was also a man in black and a thin young man.
The man in black is the old man's guard.
The thin young man was also familiar to Du He. He was Li Er's son, Li Ke, the king of Shu.
Among Li Er's sons, Du He admired Li Ke the most.
This guy is low-key but very smart.
Even the civil and military ministers recognized that Li Ke's talents and learning were superior to those of Prince Li Chengqian and King Li Tai of Yue.
It's a pity that Li Ke is destined to be unable to compete for the queen.
Because he is the child of Li Er and Yang Fei.
Concubine Yang was the daughter of Emperor Yang Guang of the Sui Dynasty.
No matter who becomes emperor, it will not be Li Ke's turn.
At this moment, the faces of Li Yuan and the guard in black were covered with notes, but Li Ke didn't have many notes on his face.
Du He stepped forward, patted the old man on the shoulder, and said carelessly: "Old man, your card skills are too bad. You have a good deck of cards, but being beaten like this by you really hurts my Du He's face.
Lost everything."
Li Ke was suddenly shocked when he heard this. He pointed at Du He and scolded: "Du He, you..."
Before he finished speaking, he was interrupted by Li Yuan: "Ke'er, shut up!"
Li Yuan handed the card to Du He: "If you have the ability, come and do it!"
Du He chuckled, took the playing cards, and won within a few strokes.
As a landlord, Li Ke was given a note.
Li Yuan wanted to continue fighting the landlord, but was stopped by Du He: "Old man, I'm very busy and I don't have time to play with you. I'm here today to fulfill my promise. I'm going to catch all the fish in the lake."
I’ll tell you how.”
When Li Yuan heard this, he was still more interested in fishing.
So he grabbed Du He and sat down next to him: "Come on, tell me, is there any good way to get all the fish in this lake?"
Li Ke next to him heard this and came over curiously.
Du He touched his chin, "Of course I have a way. I'll write down some ingredients first, and you can get them for me. The more the better!"
Du He took out the paper and pen and wrote a full article.
In addition to raw materials, there are also many tools.
Li Yuan took it and took a look, looking confused.
"What are these things used for?"
Du He smiled and said: "The gunpowder maker!"
"Gunpowder...what is gunpowder?"
Du He had no intention of hiding it: "You will know by then, so hurry up and prepare!"
Du He had no intention of hiding the gunpowder matter. Anyway, Yuan Tiangang already knew the method of refining gunpowder. Even if Du He didn't figure it out, gunpowder would start to spread in this era.
Li Yuan handed the list to the man in black.
About half an hour later, the man in black came back carrying two huge sacks. When he opened them, he found that they were full of materials Du He needed.
Du He said: "I need a quiet and dry room now!"
Li Yuan nodded: "No problem!"
There happened to be a courtyard by the lake. There was a courtyard where Li Yuan lived. The man in black immediately packed up a clean room and gave it to Du He.
Du He got into the room with the raw materials and closed the door with a bang.
In the yard, Li Yuan and others were all guarding the door, wanting to see what Du He was up to.
Li Ke raised his head, looked at Li Yuan, and asked curiously: "Grandpa Huang, why do you hide your identity from Du He?"
Li Ke is only twelve years old, but he already has a mature temperament that his peers do not possess.
Li Yuan laughed and asked: "Ke'er, how do you think ordinary people will react when they see me?"
Li Ke thought for a while and said seriously: "Of course I'm afraid!"
Li Yuan nodded and said with a smile: "I like Du He very much. In my heart, I even regard him as a friend. If I reveal my identity to him, I'm afraid I will scare him. By then, I won't even be a friend to talk to."
No."
Li Ke's confused face showed a look of confusion.
…
in the room.
Duhe has prepared all the materials.
"Fortunately, I have read a lot of information on making earthen explosives before, otherwise, I may not be able to solve this problem!" Du He said to himself.
What he told Li Yuan and others was to make gunpowder.
In fact, what Du He wanted to make was explosives.
Moreover, he plans to use this thing to fry fish.
Du He first compared the raw materials for black powder, which were nothing more than saltpeter, sulfur and charcoal. He only needed to configure them strictly according to the weight, and he could basically meet his requirements.
However, these raw materials are very rough, and Du He still needs to select and process them.
By the time he finished the black powder, it was almost dark.
On the way, Li Yuan arranged for the men in black to bring food in for him.
The freshly prepared black powder is a little damp and needs to be dried overnight before use.
After Du He made arrangements, he opened the door and saw Li Yuan and Li Ke waiting in the yard.
Li Yuan asked excitedly: "Boss Du, have you made the black gunpowder?"
Du He waved his hand: "Old man, why are you anxious? You can't eat hot tofu in a hurry. Don't be impatient. I can take you to fry fish early tomorrow morning. Then I will show you what black technology is, hehe
...It’s been a tiring day, and my young master’s bones are almost falling apart. Let’s talk tomorrow. Remember, you can’t move anything in the room. Don’t blame me for not reminding you!”
With that said, Du He was about to leave.
But Li Ke suddenly asked: "Du He, I heard people say that you always have some weird things, such as playing cards. Where did you get these things?"
This question is something that many people, including Li Er, are puzzled by.
Some people believe in gifts from gods, but some people don't.
Du He looked at Li Ke's serious look, smiled, and said, "Of course I did it myself!"
Li Ke said curiously: "But why can you do it and I can't?"
Du He scratched his head: "Because we studied different things. You studied the Four Books and the Five Classics when you were young, and I studied physics and chemistry. Can it be the same?"
After saying that, Du He waved his hand and ran away.
