Mu Jin was too busy to play the role of host, so Cao Jingzhi waved his hand indifferently.
"Girl, you should get busy. The old man won't be here for just one or two days."
"Yes, Sister Mu, go ahead and do your work. Grandfather is here with me. I've been here once before."
Li Motang replied with a smile
"Hey, look how busy I am. Don't worry, I'll let Mu Bai take you around when he has time. If you need anything, just go to Mu Bai directly."
Mu Bai had no objection to his sister's arrangement.
Cao Jingzhi didn't care, but Li Motang was very happy.
After making the arrangements, Mu Jin went to check the latest accounts of the industry.
Under Mu Bai's leadership, Cao Jingzhi and Li Motang had a great time eating and drinking.
Cao Jingzhi sighed that his trip was not in vain.
A few days passed like this.
Na Muzi came back from Beijing and went to the peach forest to find Mu Bai.
When Mu Jin saw Mu Zi, she thought of Mu Yuan.
"So, Muzi, how's your wooden kite doing?"
"Sister Mu, I came here this time to tell you about this."
When Mu Jin heard this, she became interested.
"Oh, it seems you have a new idea. Tell me about it."
"Before, I wanted to make a manned flying kite like a paper kite, but after some research, I realized that you couldn't carry anything that way, so I improved it. Look at this."
Then he took out a blueprint and showed it to Mu Jin.
Mu Jin took it and looked at it. Isn’t it a hot air balloon?
"How did you come up with that?"
Hibiscus asked in surprise.
"Ah, I also got this idea from the books you gave me. The basket below can hold things and it moves according to the wind direction. When it reaches its destination, you put the sandbags prepared inside outside the basket and it will descend."
"Naka Muzi, you are really great. You solved a big problem for me."
Namuzi scratched his head embarrassedly.
"Hehe, this is just a preliminary idea. It may not be so easy to implement in practice."
"It's okay. I'm here with you. Let's find a solution together."
The construction of hot air balloons is imminent, as it is an essential tool for transporting materials to various places.
Jiangnan consumed a huge amount of materials, and Li Fugui also wanted to shorten the time.
Choosing the water route is fast, but the cost is too high.
A month later.
The ancient version of the hot air balloon is ready.
Mu Jin and his companions conducted a test flight according to the wind direction and felt it was pretty good.
During the time when the hot air balloon was being built, the people on the mountain were not idle either, they were busy training them to use parachutes.
That's right, although they tried their best to avoid risks when building hot air balloons, they were still afraid that accidents would still happen.
So a group of people were trained to transport goods by hot air balloon.
If an accident occurs, you can escape by parachute. Nothing is more important than life.
Seven days later.
The first delivery team is ready to go.
After flying for a day and a night, we arrived in Jiangnan.
Those who went there would stay there and wait for the wind to turn right before flying back.
With this move, transactions between the two sides became frequent and close.
Li Fugui even expressed his desire to place a private order for a few.
The Li family has businesses all over the place, so having a hot air balloon is much more convenient.
After receiving the news, Mu Jin hurried to find Na Mu Zi.
"Muzi, we have a big order. Your hot air balloon is amazing. Here is the deposit."
Na Muzi felt numb when he saw the stack of banknotes.
"Sister Mu, that's not possible. I just provided an idea, and your help is indispensable. I don't want the money."
Mu Jin stuffed the money directly into Mu Zi's arms.
"What nonsense! You made so many hot air balloons for me without charging me a penny. Those are worth much more than this."
"Besides, without your ideas, we wouldn't be able to do these, right? Muzi, you are our hero."
Mu Bai held down Mu Zi's hand as he was about to push it back.
"Hurry up and put it away. Why are you being so polite to us? You still have to get married. Don't keep the girl waiting too long."
