"Well, you don't need anything particularly hard to find." Xia Hongsheng sighed and said to Yuan Tiangang: "It's just that the materials needed are a little difficult to find, so it is definitely not easy to buy." ”

"Poor Dao, this immediately called on the people of Chang'an Daomen to donate copper coins! It's not a problem to want to collect 500,000 yuan. Yuan Tiangang was convinced of Xia Hongsheng: "500,000 is enough?" If it is not enough, the poor Dao will gather people from all over the world to donate money! ”

Poof-Xia Hongsheng squirted out a mouthful of water, and waved his hand again and again: "No!" Or not!

It turns out that being a god stick makes so much money!

Xia Hongsheng came to Yuan Tiangang to do it, not because he wanted his money, but because he was a disciple of the Taoist sect to find some hard-to-find materials. But I never thought that such a huge tyrant would be blown up!

Seeing Xia Hongsheng waving his hand, Yuan Tiangang said again: "How much money does it cost?" Or do you need manpower and material resources? I, Taoism, am willing to bear it with all my might, and please make it clear to Xiahou! ”

Xia Hongsheng nodded: "Since Daoist Yuan is willing, then I will ask Daoist Yuan to go to the academy tomorrow." The drawings for the artifacts were made in Jingyang. In the next preparation, it will be made in Jingyang Academy. ”

"Why don't I go to Jingyang now!" Yuan Tiangang couldn't wait for a moment, and was about to get up immediately.

"The road is long and slow!" Xia Hongsheng stopped Yuan Tiangang, who was about to call someone to prepare the carriage, and said to him: "There are still things to do in Chang'an City today, and I can't get out of it for the time being." The Taoist chief is also ready to prepare, that thing can not be made in a while and a half, the Taoist chief has to be prepared to live in Jingyang for a long time. If there is anything that needs to be arranged, it is better to arrange it first. ”

"It's okay......" Yuan Tiangang finally calmed down, nodded, and said.

Xia Hongsheng is not in a hurry, anyway, Li Lao Er said that it will take at least a year to prepare a dowry for Li Lizhen. One year is enough time for him to make it.

As for why he didn't do it himself, but wanted to pull Yuan Tiangang, in fact, Xia Hongsheng had his own considerations.

The biggest reason, of course, is that many of the materials used to make hot air balloons are not available at present, and it is necessary to find alternative materials and technical solutions. With Xia Hongsheng himself, although he has traveled to the Tang Dynasty for several years, he does not know the world as well as the native Tang people. What's more, there are many Taoist believers, and if you can mobilize the power of Taoism to find something, it will be too convenient.

And go, if this hot air balloon is really made and successful, Xia Hongsheng estimates that this object will not escape the clutches of Li Laoer. I'm afraid that when the time comes, I will rush into the military aircraft workshop and enter the secret category, and then I won't be able to do anything. So borrow Yuan Tiangang's hand to do it, and when the time comes, it will really be occupied by Li Laoer, and he will have nothing to lose. Anyway, the person who designed the hot air balloon is himself after all, if he is really taken by Li Laoer, this credit will not be able to run. Sharing Yuan Tiangang's piece of the pie, he is not missing anything, but he has lost his credit, and there is no loss, and he can also earn a great favor from Yuan Tiangang and Taoism, and he can count it in one fell swoop, why not.

However, in addition to Yuan Tiangang, another group of people had to join in.

So Xia Hongsheng didn't let Yuan Tiangang go to Jingyang immediately, he had to go back and make sense first.

After saying goodbye to Yuan Tiangang from Xuanduguan, Xia Hongsheng turned to Yanyu Building and asked Qi Yongyi to inquire, saying that the group of gentlemen had been taken back in the morning, so he left with peace of mind, and did not go back to the house, so he went directly to Jingyang.

Run all the way, don't say much.

When he arrived in Jingyang, Xia Hongsheng went to greet his sister-in-law first, and then went straight to Youji's courtyard.

Unexpectedly, Youji was taking a nap, and Xia Hongsheng didn't wait for her to wake up, and directly pushed the door and went in.

"Yuhime, what about the drawings you took from my study? Get it out of here, I'm going to make something! After pushing the door in, Xia Hongsheng asked directly.

Youji was awakened, and when she saw that it was Xia Hongsheng, she couldn't help but look at him with some annoyance, and said angrily: "When the concubine was a child, did she take the drawings in the child's study?" It's the son, how suddenly he broke in, disturbing people's dreams in vain! ”

Xia Hongsheng smiled and said, "What do you sleep in the daytime, the autumn wind outside today is not cold." Hurry up and give me the drawings, the ones you took from the wooden box in my study. ”

Yuhime got up from the bed, walked to the front of the cabinet and opened it, took out a wooden box from it, and opened it to be the pile of drawings. She took out the drawings and handed them to Xia Hongsheng, and said, "What is the thing that Childe draws?" The concubine guessed for a long time and didn't figure it out. Look at this thing with a cover on top and a fire below, isn't it an object like a Kong Ming lantern? ”

Xia Hongsheng nodded, and while taking the drawing, he said: "Yes, the principle is basically the same as that of Kong Ming lanterns, but they are bigger than Kong Ming lanterns." ”

"Then this object can fly to the sky at a glance with Kong Ming's lantern?" Yu Ji asked again: "The concubine has been looking at it for a long time, and she can't think of what this thing can do. ”

"If this thing is done, it will allow people to sit in it and fly into the air." Xia Hongsheng said to Youji: "I'm going to the academy now, you took a lot of drawings from me, remember to keep it, but don't lose it." ”

After that, Xia Hongsheng didn't stay long, so he hurriedly left Youji's place, and went to the academy in a row.

The other person Xia Hongsheng was looking for was the Mo family's Juzi Letai, who was now teaching in the academy.

The Mohist machine technique is amazing, even if it is not as powerful as rumored, but it must also have a deep attainment and experience in machinery.

To make a hot air balloon, Xia Hongsheng knows the principle, and Xia Hongsheng also knows the structure. But Xia Hongsheng knows that it does not mean that it can be made with today's technology and materials.

This requires the help of musicians and others who are proficient in mechanical techniques.

In this way, Xia Hongsheng contributed technology and design, Yuan Tiangang contributed material resources and required money, and Letai and others contributed manpower to transform Xia Hongsheng's design into reality. The three work together to make a hot air balloon as much as possible.

Moreover, setting the location of making hot air balloons in Jingyang Academy can also attract the interest of the students of Jingyang Academy, let them see the power of Gewu, and also attract them to study this way.

Flying people into the air, Xia Hongsheng could imagine how shocking it would be if the young students in the academy saw this situation.

And this shock will also make these students realize that they are in contact with a new and divine world. (To be continued.) )
