Feng Chong was very busy during this time, studying these explosive beads while controlling water and opening canals.
There are some gains.
This can be seen from the things Gu Qingshu brought.
However, Feng Chong still preferred to place the fried beads in a bamboo tube.
Then use it like a flare.
This idea is quite avant-garde.
"Your Highness thinks that if a bamboo tube can hold a dozen signal firecrackers, it can also hold a dozen explosive beads." Gu Qingshu rushed over and ignored Su Yiheng. He was more interested in making explosive beads.
Su Qianyue nodded: "He mentioned this in his letter."
She also wrote back and explained to him.
I didn’t explain much to Gu Qingshu.
"Miss Su, what suggestions do you have?" Gu Qingshu was serious, completely different from before.
Not as crazy as before.
Su Qianyue didn't pay much attention to this point. She took a piece of enlightened paper and the graphite pen she had processed and started to draw a mechanical diagram.
While drawing, he explained: "In the final analysis, a flare is just a kind of firework. It is pushed out of a bamboo tube and the requirements for ignition are not high."
Gu Qingshu on the side had already taken out a pen and paper and started recording.
Still a good student.
Even Su Yiheng, who came over with an annoyed look on his face, was a little surprised.
It seems that Gu Qingshu's Jiangnan weaving is not in vain.
Of course, if he didn't have the real ability, Feng Chong wouldn't have sent it all the way.
When Gu Qingshu started working, he was serious, steady and more like a good student with both good character and academic performance.
This attitude makes people very happy.
"Indeed, I have also considered this. Changing the bamboo tube to one made of iron should have better effects." Gu Qingshu nodded, with a very serious look, "The iron tube can make the ignition point unrestricted.
I just couldn't push the bead out."
He has tried many experiments but has always failed.
However, the idea put forward by Feng Chong made him not want to give up.
"Master Gu is indeed smart, and here's the key." Su Qianyue kept her head lowered and her hands never stopped.
She drew a structural diagram of the most primitive iron fire gun.
Annotations are added everywhere.
Not only was Gu Qingshu confused, but Su Yiheng also looked incredulous. He didn't understand the principles of explosive beads or flares, but he understood the picture made by Su Qianyue.
"Little sister..." Su Yiheng really wanted to know how Su Qianyue understood these things.
"The principle is the same as that of firecrackers, but it must have a certain degree of lethality." Su Qianyue began to explain the principle of firecrackers, "And for the convenience of use, I think the iron barrel lasts longer and will not cause self-injury.
"
In fact, Feng Chong and Gu Qingshu had already used bamboo tubes to install the simplest muskets.
It can only be used once, and there is a certain chance of self-harm.
Therefore, it is not suitable for use on the battlefield.
Such a breakthrough also impressed Su Qianyue.
She had been exposed to these things in her previous life, so she could speak clearly and eloquently.
However, Feng Chong and Gu Qingshu were able to invent through ideas and practice. They were indeed smart enough.
"Well, His Highness and I have also thought about this, but the iron tube needs to be longer." Gu Qingshu's eyes were also shining, "It is good for burning."
"This, we need to change our thinking." Su Qianyue smiled, "Instead of firing explosive beads as weapons, we can use explosive beads as ignition point to launch stones and steel balls, which can also hurt people."
What she said was also very simple.
Even Su Yiheng on the side understood it, his eyes brightened: "Yes, this is a good idea, little sister."
Su Qianyue was a little embarrassed, this was not her idea.
She's just picking on people's wits.
However, she couldn't explain it.
"Well, that's a good idea." Gu Qingshu nodded, and the smile at the corner of his mouth became a little deeper. He felt like he was enlightened and enlightened, and he moved closer to the drawings to look at them carefully.
At this moment, he only had blueprints in his eyes and nothing else.
It actually made Su Yiheng feel a little more relieved.
He gave some instructions to Qingzhe and Zinnia on the side.
He came here just to keep an eye on Gu Qingshu. If Gu Qingshu dared to have any wrongdoings with Su Qianyue, even if he was a member of the Second Prince Feng Chong, he would be destroyed.
