Until the moon reaches the zenith, the tung oil lamp has burned out.
The room is dimly lit.
Zhang Jian stood up slowly and picked up the money bag on the ground.
The beautifully crafted money bag itself was valuable, and only a dandy like Du He could afford it.
Zhang Jian curled his lips, opened it, and counted more than five hundred coins inside.
Suddenly, he opened his mouth in surprise.
After a while, Zhang Jian suddenly felt overjoyed and rushed out of the house like crazy: "My mother's illness has been cured, hahaha..."
Under the moonlight, his running figure staggered a little.
Not long after, Zhang Jian came to a medicine shop in the square and banged open the door.
"Shopkeeper, please get me some medicine quickly. I have 500 coins now."
…
On this day, when Du He was preparing to take a nap, someone suddenly arrived in the palace.
The person who came was none other than Ximen Qing.
When Ximen Qing saw Du He, he was particularly enthusiastic: "I've seen Lantian County, but I haven't seen him for a few days. The county seems to have grown a lot taller."
Du He said with a smile: "We haven't seen you for a few days, and Mr. Ximen's complexion is getting better and better. Maybe he found some money."
Ximen Qing laughed: "The county is joking. I came here today on the order of His Majesty to get the method of making explosives. Your Majesty said that you are young, and I'm afraid you will forget it as time goes by, so you asked me to do it myself."
I'm here to remind you that if it's not ready yet, we'll go back and report it to Your Majesty, telling the county magistrate that you've been working hard for days and don't have time to prepare, so just come back and pick it up another day."
This Ximen Qing is a good person. With a few words, he unknowingly came to Du He's side. Regardless of whether it was true or not, it made people feel comfortable.
Du He waved his hand: "I can't let Mr. Ximen make your trip in vain. Please wait a moment, and I will write down the method of making this explosive for you to take back."
With that said, he asked Old Fu to greet Ximen Qing, while Du He returned to the room.
Sitting at the table, Du He spread out the paper, picked up the signature pen, and started writing like a snake.
The only sound in the quiet room was the scratching of the pen tip across the paper.
After a short time, Du He put down his pen, picked up the two pages full of writing, and said with satisfaction: "It's done!"
The title is "On How Explosives Are Made". The first part introduces in detail the production method and combustion principle of gunpowder. The second part introduces the explosion principle of explosive packets and the method of making explosives.
If this was done in future generations, a high school student could do it.
However, in this era, such an article can be said to be of infinite value.
Simply put, this article deserves the title of Lantian County Prince.
When Du He returned to the living room and handed the article to Ximen Qing, he only heard Ximen Qing say: "Oh, the county is really talented. If you don't say anything else, just this handwriting, your majesty is always full of praise, like
There are not many outstanding young talents like this in the world."
Du He sounds gross, but it is very useful.
After Ximen Qing carefully put away the things, he quietly thrust a piece of silver into Ximen Qing's hand.
Ximen Qing came to Du He's ear with a smile and whispered: "The county does not know something. After you left after having dinner at Wende Palace that day, both your Majesty and the Queen praised you. The Queen even felt that with your talent,
It’s a pity to be a prince-in-law!”
Du He was moved in his heart and asked: "What is Your Majesty's attitude towards my playfulness with Princess Changle?"
Ximen Qing whispered: "Your Majesty didn't say anything, so he probably wasn't angry. If there is any news in the future, our family will definitely send you a message to the county magistrate, hehe..."
Du He nodded: "Thank you, Manager Ximen."
Only then did Ximen Qing leave with satisfaction.
Du He looked at Ximen Qing's leaving figure, and a bold idea suddenly appeared in his mind, but he immediately shook his head and rejected it.
This idea is too bold. Once Li Er discovers it, marrying two princesses will probably be ruined.
Besides, Ximen Qing brought the article "On How Explosives Are Made" back to the palace. Li Er casually looked at it and called Yuan Libin, the young eunuch of the Shaofu.
At the beginning of the founding of the Tang Dynasty, the Weapons Supervisor was established to take charge of the manufacture of weapons. However, as the wars decreased, the Weapons Supervisor was abolished in the sixth year of Zhenguan and merged into the Shaofu Supervisor.
Yuan Libin is a young eunuch of the Shaofu Jian, a sixth-grade official.
Li Er handed the article to Yuan Libin and said: "I will give you three days to make an explosive package. I will be there to review it in person."
Yuan Libin said hurriedly: "Your Majesty, please put it down. We will do our best to make the explosive package."
Yuan Libin was too young to see what happened that day by the lake in Dongneiyuan, but when people around him talked about it, they were all horrified.
Now that he had the method of making explosives in his hands, he became excited.
Then I heard Li Er say: "This method was donated by Du He, the son of Lantian County. Everyone involved in this matter must keep it secret. If anyone leaks the information, the Nine Clan will be punished."
One sentence made Yuan Libin's face pale with fright.
Yuan Libin took this article "On How Explosives Are Made" back to the Shaofu Prison. He closed the door and studied it alone for several hours, but he was completely confused.
It turns out that although Du He's article was written in vernacular, it was full of professional terms. Later generations would not think much of it when reading it, but people of this era were a little sleepy.
For example, the word "lead" made Yuan Libin scratch his head and couldn't understand it for a long time.
Finally, Yuan Libin had no choice but to call the two deputies from the Shaofu Supervisory Department of Ordnance to discuss the details, and finally understood a little bit.
A deputy said: "Sir, this son of Lantian County is really a god. He can actually come up with such a method. According to my opinion, the principle of making this explosive is beyond our comprehension.
It's better to experiment according to the method honestly. As for the principle, I'm afraid only Lantian County Master in the world can understand it."
Yuan Libin nodded in agreement: "Yes, we only need to make the explosives. As for why it can explode, that is not our concern."
Immediately, Yuan Libin arranged for several close men to start developing explosives.
…
Three days later.
Li Er sent Zhao Yang to the Duke of Lai's Mansion to invite Du He to the palace to watch the experiments on the explosive packs developed by the Shaofu Supervisory Ordnance Department, but Du He refused outright.
Du He only said one sentence: "There is a guy named Nobel who blew up his whole family just because he was playing with gunpowder. I will not do such things as experimenting with explosive packs!"
When Zhao Yang brought the words to Li Er, Li Er disagreed: "Huh, this boy is alarmist. He thinks the title I gave him is too small and is dissatisfied. However, my explosives have been successfully made. Let's see if he can still do it."
What can be done? Even if he is dissatisfied, it is too late! "
Li Er felt happy when he thought about Du He's unhappiness.
