Seeing that my father was finally inspired, through the principle of grinding the disc, he finally knew how to convert the irregular work power of steam, which keeps rising and falling against the lid of the pot, into a stable source of power, and I was very happy and excited.

I really look forward to the day when he can invent a steam train, on the track of Daming, whining forward.

Then he can be said to be the father of the first steam of the Ming Dynasty, and it will bring incomparably huge changes to this era, and it is a real earth-shaking change, even more amazing than Zhu Houxuan's succession.

I can't say that I can really eat hot pot and sing songs when I go out in the future, and I am very excited to think about it, and I have a feeling of steampunk inexplicably!

However, after the excitement, he also calmed down, because he also knew that even if his father understood all the principles, it would not be easy to successfully research the steam engine, and even the steam train, it would still be difficult.

In the final analysis, the industrial level of this era is too backward, no, it can even be said that there is no industrial level, or the era of small-scale peasant economy, it is simply unrealistic to want to jump to the era of the industrial revolution, step by step, and you can't be in a hurry.

Otherwise, the step is too big, click, and it is easy to pull the egg.

Anyway, it will take at least twenty or thirty years before he can first see the scale, and he will have to wait slowly.

After all, laying a railway is not a simple matter, I don't know how much manpower, material and financial resources will be spent, especially in this era of industrial backwardness, it is really similar to Qin Shi Huang building the Great Wall.

Think about how much time Qin Shi Huang spent on building the Great Wall, and how much effort he put in, you can imagine.

So after calming down, fortunately did not delay much, after seeing that it was not early at this time, he also returned to his house, simply ate some things, that is, took out a pen and paper, first drew a few simple sketches, revised and modified, and after all were about the same, he went to bed and waited for the next day.

There was no book all night, and soon, the time of the night passed.

The next morning, I got up early and fortunately, I also received something from Zhu Houxi.

The person who came was a small steward of the Xingwang Mansion, responsible for the purchase and other things in the palace, and led a large group of people to send the things he needed, and said happily.

"Childe, these are almost what you need, a hundred special nitrate cowhides, waterproof and moisture-proof, and non-flammable, which are very much in line with your requirements."

"In addition, there are fifty embroiderers and fifty craftsmen, all of them, you see if you need anything, even if you ask, the prince said, if you have any requests, just give orders, and we will do our best to do it."

Hearing this person say this, he looked at the hundred cowhides he had people move in, and the large group of people who followed him, fortunately he couldn't help but nod with satisfaction, and in addition to surprise, he couldn't help but be a little surprised, and he was quite surprised.

"Really, so fast? I thought I'd have to wait a while, but I didn't expect you to do it so quickly. ”

Hearing this, I saw that the chubby steward Liu Quan also squinted his small eyes and said a little proudly.

"Hehe, Childe has won the award, it's okay, although it is a little troublesome to collect these things, but since it is your order, we will definitely go all out, of course, this is also for our Xingwangfu, if you are someone else, it will definitely not be possible."

"Let's just say that these hundred cowhides, most of them are made of nitrate after you left yesterday after the prince ordered him to be slaughtered immediately, other people definitely don't have the courage to touch this mold, I think the prince also understands, so the prince is really open, and he pointed to the prince to give him a big surprise in three days."

"Really? It's really embarrassing for the prince. ”

Nodding, he could hear Liu Quan say this, and fortunately he also knew it, because he did know that in this era, slaughtering cattle was a crime, and ordinary people really didn't have the courage.

Even if it is Zhu Houxi, as a prince, it is enough to choke, if it is in normal times, it is enough for the royal historians who learned the news to participate in him fiercely.

It's just that as I said before, now is an extraordinary time, so naturally I can't care so much, so why don't you love it.

After all, if this thing is done, it will really be done, the whole world is his, and slaughtering a few ploughing cattle is basically a trivial matter for a son of heaven.

If it doesn't work, it will be gone, and he will continue to be his prince in peace, even if it is known by those imperial historians.

After all, in the Ming Dynasty, as long as you don't rebel, even if you do something illegal and undisciplined, it's not a big deal, at most you will be fined, and the little money in the court is really insignificant to Zhu Houxi, I don't care at all, and I haven't found a reason to collect rent casually.

So fortunately, he also said with a smile.

"Don't worry, Steward Liu, please go back and tell the prince, I promise I won't let him down."

As he spoke, he saw that Wan Xing personally stepped forward and touched the stacks of thick cowhide, which was indeed very tough, and it was made of special techniques, and it was elastic, and there was a feeling of invulnerability, which was very in line with his requirements, and it was indeed the best material for making hot air balloons.

And each one is in good condition, without damage or wrinkles, and I can't help but nod with satisfaction and smile.

"Well, it's very good, Steward Liu has a heart."

As he spoke, he turned around and pointed to the fifty women behind Liu's body.

"By the way, Steward Liu, are these fifty sisters all embroiderers you found?"

Nodding, Liu Quan said with a smile.

"That's right, Childe, these fifty sisters are the embroiderers I found, but they were hired at a great price, and they are the most skilled embroiderers in our country, so you can rest assured that they can meet any requirements."

"yes, that's great."

Overjoyed, Wan Xing nodded excitedly, and then hurriedly took out the hot air balloon drawings drawn overnight last night from his arms, and came forward to say to the fifty embroiderers.

"Thank you sisters, look at these drawings, can you use these hundred cowhides to help me sew five of these cowhide balloons in three days?"

"Cowhide balloons?"

Immediately, hearing this, the fifty embroidery women couldn't help but be stunned for a moment, a little unclear, they hurriedly took over the drawings in his hands, circulated them to each other, and said with a smile.

"It turned out to be something like this, no problem, childe, three days, although we were in a hurry, but if we stayed up late to catch up with the work, we could still sew the strange balloon you drew on the picture."

"That's right, although this cowhide is a little difficult to sew, but you can use a large needle and thread, I think it shouldn't be a problem, but I don't know if Childe has any other requirements?"

Hearing them say this with confidence, it is worthy of the exquisite embroiderers found by Xingwangfu at a great price, and they are not only happy, but also hurriedly said.

"Then thank you sisters, there are no other requirements, just one point, that is, except for the air intake below, that is, the circular opening under the balloon you see on the map, the rest of the entire balloon must be sealed, that is, closed, not breathable, sisters, can you do this?"

"This ......"

Hearing this request, the group of embroiderers was a little difficult, thought about it, looked at each other again, and discussed in a low voice around for a while, then nodded.

"Childe, it's not impossible, you just need to fold and sew the place where the two pieces of cowhide are connected when sewing, and the stitches are denser."

"It's just that in this way, the sewing is very difficult, time-consuming and labor-intensive, and we are afraid that we will not be able to complete it in three days."

Hearing them say this, Wan Xing also hurriedly said.

"It's okay, sisters, please work overtime, because it's really important to us, so as long as you can finish it in three days, how about I double your pay?"

Including Liu Quan, the steward of Xingwang Mansion on the side, also promised.

"That's right, little ladies, I'll leave it to you, rest assured, as long as this matter can be completed on time, I will definitely be rewarded for Xingwangfu."

Hearing them both say this, the group of embroiderers looked at each other again, gritted their teeth, and nodded.

"Okay Wan Gongzi, Steward Liu, let's try and strive to complete it within three days."

"Okay, sisters, then don't delay, you start quickly, a group of ten, each group sews twenty cowhides, and strives to complete it within three days, rest assured, the food and clothing for the next three days are all solved by us, you can sew with peace of mind."

Saying that, fortunately, he beckoned his little maid Su Xue to come and said to her.

"Cher, have you remembered the key and details of sewing cowhide balloons that I told you last night? But don't forget, I've handed over this group of embroiderers to you, and you guide them to complete it, and if something goes wrong, I'll ask you. ”

Immediately, she was entrusted with a heavy responsibility, and in addition to being excited, the little maid Su Xue also immediately held her head high and said.

"Childe, don't worry, remember it clearly, don't underestimate me, isn't this cowhide balloon similar to the enlarged version of Kong Ming lantern, you can take me to let it go every year during the New Year, it's very simple, we can't paint cats and tigers, just leave it to me, I promise not to make mistakes, you just wait and see."

"That's good, go ahead, that's what you said, then I'll wait to see your good news."

Seeing that the little maid said this with confidence, she nodded with a smile, and did not delay, fortunately, she waved her hand directly, and let her take this group of embroiderers to the backyard of Wanjia, set up tables and benches, and began to work overtime to sew cowhide balloons.

Let them strive to make five of these cowhide balloons within three days, so as to help them go to the capital faster, so as to catch the group of court princes off guard.
