Chapter 237 Brother-in-law, it’s not that I don’t trust you
Listen to what Sumood said.
Qin Yu waved his hand and said calmly: "It doesn't matter, this budget is enough for me. Don't worry, Mr. Su, what I am best at is spending small money to do big things."
"this......"
Sumood was a little embarrassed, and said with a wry smile: "Okay, since the prince-in-law has said so, if I say anything else, it will be my pretentiousness."
To do such a big thing.
Qin Yu said that he only needed five thousand taels of silver.
Sumao De was really amazed at Qin Yu's ability.
Although the work has not been done yet, he has full confidence in Qin Yu.
Qin Yu said calmly: "Okay, let's leave the matter of entertaining the old man to Mr. Su."
Afterwards, Qin Yu and Xiao Nan stayed in the Ministry of Rites for a while and then left.
Out of the Ministry of Etiquette.
Xiao Nan looked at Qin Yu with a confused look on his face, "Brother-in-law, are you... are you a little overconfident? Five thousand taels of silver, a Thousand Old Man's Banquet for thousands of people, this...
.This is just a New Year’s Eve banquet, and the money is not enough!”
Qin Yu smiled indifferently and said thoughtfully: "What stands out this time is frugality, otherwise it will violate our original intention. There is no point in whitewashing the peace."
"Besides, don't you feel at ease when I'm here? Besides, the watermelons in your greenhouses are enough. Who can eat watermelons in winter? That's a fairy-like treatment."
"???"
Xiao Nan's eyes widened and he looked confused, "Brother-in-law, that... I grew it with great difficulty, you can't just give it to me to eat!"
Qin Yu waved his hand, "It's all your contribution to the country."
Xiao Nan: "..."
...
The next day.
early morning.
There are still four days until New Year's Eve, time is tight and tasks are heavy.
Qin Yu had no time to delay and started preparations.
He took Shen Binglan and Xiao Nan straight to the firearms workshop.
When Qin Zhang learned that Qin Yu had taken on such a big job, she was naturally very happy, so she asked Shen Binglan to follow him and protect him.
Qin Yu planned to do something with a sense of ritual first.
On the road.
Xiao Nan looked at Qin Yu with a tangled expression.
Qin Yu looked at his appearance and asked doubtfully: "If you have anything to say, why do you have such an expression?"
Xiao Nan frowned and said weakly: "Brother-in-law, it's not that I don't trust you, you... you said you wanted to make something ceremonial for the Qiansou Banquet, why should we go to the firearms workshop?"
for this question.
Shen Binglan was equally confused, but she didn't ask.
The firearms workshop is where gunpowder weapons are made.
They really couldn't figure out what kind of ritual things Qin Yu could make from the firearms workshop.
They didn't know whether it was a ritual or not, but they believed it could blow up the palace.
Qin Yu listened and smiled calmly: "That's it? There's nothing difficult to understand, because I need to use gunpowder to make fireworks. I'm not bragging to you. As long as I make this thing, the ritual sense of the Thousand Old Banquet will be filled instantly.
.”
fireworks?
Xiao Nan and Shen Binglan frowned at the same time.
This is something they have never heard of or seen.
"Brother-in-law, what are fireworks?"
Xiao Nan looked at Qin Yu and asked.
Qin Yu explained: "The structures of fireworks and firecrackers are similar. They both use gunpowder as raw materials, but making fireworks requires more complicated pyrotechnic powder. As for the effect of fireworks, do you all know the stars in the sky?"
Xiao Nan and Shen Binglan nodded.
Qin Yu continued: "Fireworks fly up into the sky, giving the effect of a sky full of stars. The visual impact is extremely strong. The key is that we can make this thing ourselves, and the cost is low."
A sky full of stars?
Xiao Nan and Shen Binglan seem to have a vague sense of the picture.
Even though Qin Yu explained it, they didn't understand it very well.
But they didn't continue to ask, after all, they still didn't understand.
Immediately, the three of them rode horses all the way to the firearms workshop.
...
Firearms Workshop.
Warm Pavilion.
Qin Yu, Xiao Nan, Gu Tao and Shen Binglan were sitting in the room.
Gu Tao held the sketch drawn by Qin Yu in his hand and exclaimed, "Hey, little prince, your understanding of gunpowder is beyond the reach of a villain, and your imagination is unprecedented and unprecedented.
”
"You mean, if you use copper powder as a luminescent agent and add copper powder to gunpowder, the gunpowder will emit green light when it burns? If you add...add this sodium, it will emit yellow light?"
He has some knowledge of gunpowder.
But the more this happened, the more Gu Tao admired Qin Yu for what he knew and thought.
Qin Yu nodded slightly, "Yes, that's what I mean. You have a very strong understanding."
Gu Tao smiled helplessly, "This villain's understanding is worthless compared to the imagination and creativity of the young prince."
He really convinced Qin Yu.
It took him several years just to prepare the gunpowder ratio, and the effect was not even a little worse than the formula Qin Yu gave him.
Nowadays, Qin Yu is no longer limited to the production of gunpowder weapons.
At this time, Xiao Nan and Shen Binglan had some understanding.
Because they also know that green fire will appear when copper is roasted with fire.
But it's incredible that Qin Yu was able to connect this phenomenon with gunpowder and make fireworks.
How can the gap between people be so huge?
If Qin Yu said that he was an immortal descending to earth.
Neither Xiao Nan nor Shen Binglan would be surprised.
Qin Yu looked at Gu Tao and asked, "How's it going? Is there any problem with making the fireworks?"
Gu Tao's eyes flashed with perseverance, "No problem! Of course there is no problem! I will do my best to do what the young prince has asked me to do."
Qin Yu smiled and said, "No problem, I will make it for you together."
Afterwards, Qin Yu and Gu Tao went to the simple research room.
This place was originally an abandoned imperial mausoleum.
The reason why Qin Yu suggested choosing this place.
One is because it is quiet enough here.
The second reason is that there is a lot of potential for development and utilization here.
Once the firearms workshop develops, it will become the Wei arsenal in the future, and its scale will definitely be very large, so Qin Yu planned the future land use in advance.
Gunpowder and raw materials are very abundant.
But Qin Yu needs to purify the luminescent agent, such as sodium.
Qin Yu found some sea salt and prepared to purify sodium chloride.
Sodium chloride is the white crystalline, main component of sea salt.
The purification process is not complicated, just evaporation and crystallization, filtration, washing, and drying.
As for copper powder, it's easier to get.
Calcium Qinyu also needs to do some.
There are not even fireworks in this era.
Qin Yu feels that with three or four colors, he can already stun the audience.
After the luminous agent is ready, it’s time to make the fireworks.
The principle is not complicated either. The gunpowder is divided into two sections, one for advancement and one for ignition and explosion.
Been busy for most of the day.
Qin Yu and Gu Tao just made three fireworks bombs.
