Liu Laoshi's father-in-law was seriously ill. In the afternoon, he received the news and took his three sons to the Yue family in Lantian County. He didn't care about Zhuangzi. Fang Jun had to give up and coaxed Princess Jinyang to sleep, promising to start studying how to do it tomorrow. It’s about flying into the sky, but it’s natural to tell a story to the little princess...
A night of silence.
Early the next morning, Liu Laoshi, who was rushing back, heard that Erlang was looking for him, so he came over early to wait for him. When he arrived at the door of the study, he happened to meet Wang Erxiao. When the two entered the study, they saw Fang Jun handing over a stack of books from the desk. Liu Laoshi was immediately excited about the drawings, and he respectfully took them with trembling hands.
Nowadays, Fang Jun's study has almost become the most important place in Zhuangzi. Wu Meiniang has warned the guards and domestic servants in Zhuangzi that they must not go near the study at ordinary times. If anyone is suspicious, they can immediately capture it.
Only Wu Meiniang, Lu Cheng, Liu Laoshi, Wang Erxiao and others in the entire Zhuangzi could enter and leave the study, and even Fang Jun's personal maids Qiao'er and Zheng Xiuer could not.
These people all understand the value of every "fantastic idea" of Fang Jun, so the study room that collects some of Fang Jun's drawings is naturally a top priority.
Liu Laoshi and Wang Erxiao got together, heads next to each other, looking at the drawings in their hands, becoming more and more confused as they looked...
Oval wooden frame, pieces of thick cloth of the same shape, wicker basket, round stove, bellows...
What the hell is this?
Fang Jun's two technicians were confused. It wasn't until they turned to the assembly diagram at the back that they figured out something.
Is it a big lantern?
Don't blame these two for being rare and strange. In fact, there was no such thing as balloons in the Tang Dynasty at that time, so the two of them used hot air balloons as big lanterns. If it wasn't a lantern, why would they light a fire?
"Is it difficult to make this thing?" Fang Jun asked as he saw the two of them looking at the drawings.
"I wonder if Erlang has any request?" Liu Laoshi is more cautious and thinks about things more thoroughly.
"Requirement?" Fang Jun thought for a while, and it seemed that nothing was missing, so he said: "The only thing is, no matter which part, the exquisiteness and beauty are secondary, the most important point is that it must be as strong as possible! Ben Lang You don’t want to fly into the sky, or the rope breaks or the ball cracks, and you fall down and become a pulp!”
It's okay for him to say that if he throws Princess Jinyang into trouble, His Majesty Li Er won't need to deal with her, and he will blame himself to death!
But thinking about it, there is no big problem. Although the quality of materials in this era is not very good, his requirements are not high. He does not need to fly very high, as long as he can fly a few meters above the ground.
He is not crazy enough to want to fly over the Great Wall in a hot air balloon made from primitive materials of this era...
"Fly... fly into the sky?" Wang Er's little eyes were as wide as copper bells, thinking that he had tinnitus and auditory hallucinations.
Of these two, when it comes to simple association, Liu Laoshi is better.
Liu Laoshi carefully looked at the drawing over and over again and asked: "How come Erlang's big ball... looks like a huge Kongming Lantern?"
Fang Jun patted his thigh and extended his thumb to Liu Laoshi: "Correct answer! This is a huge Kongming Lantern, but I call it a hot air balloon."
Liu Laoshi scratched his head: "Could it be that Erlang wants to sit on this thing and fly into the sky? That's not possible. I have never heard of a Kongming Lantern that can carry people to the sky. Even if it is hundreds of times bigger... Huh? That's not right. !The buoyancy of a small Kongming Lantern can carry small things up to the sky, so it stands to reason that this Kongming Lantern, which is countless times larger... The hot air balloon can indeed be countless times more buoyant than the Kongming Lantern, so it can naturally carry larger things up to the sky. !”
Subconsciously, he looked at Wang Xiaoer and both of them were a little shocked.
Erlang’s head is so awesome!
Logically speaking, it is indeed possible!
But why has no one thought about expanding the Kongming Lantern countless times to carry people to the sky throughout the ages?
Wang Xiaoer was convinced and said: "Erlang, you are really a Wenqu star from the sky who has descended to earth. You have such a big head that no one can imagine!"
Fang Jun's face is a little dark...
You are not human!
But there is no reason to argue with this hardworking blacksmith. In his heart, he is praising him!
"Okay, okay, hurry up and prepare. If you are short of materials, let the butler buy it. No matter how much it costs, make it for someone as soon as possible. But remember, you can't cut corners or be vague. You must strive for excellence in every link.
!”
Safety is the top priority! It’s not too much to ask this several times.
The two "senior technicians" nodded sharply, indicating that they remembered it.
Just at this moment, Li Tai walked in from the door.
I forgot to mention that since Prince Wei came to Zhuangzi, he was the only one who came in and out of the study at will, along with Princess Jinyang.
No one can stop Li Tai, and no one can stop Princess Jinyang...
Li Tai was naturally aware of Fang Jun's accomplishments in promiscuous skills. When he saw this posture, he immediately understood that Fang Jun must have developed something new, so he snatched the blueprint from Liu Laoshi's hand and sat down.
Sitting on the chair, I looked through them one by one.
Liu Laoshi's face turned red. Although he was extremely unhappy, he didn't dare to turn his face. He glanced at Fang Jun and saw that his second son didn't have any displeasure, so he shut up.
"Hiss...this is a Kongming Lantern, right?"
I have to say that Li Tai is really smart. No wonder he studies well and is known as a talented person. He could tell the clues about this hot air balloon just by taking a glance at it.
"I said, Fang Er," Li Tai applied to look at Fang Jun strangely, and raised the drawing in his hand: "Don't you want to be a Kongming Lantern to fulfill your promise to Si Zi?"
Fang Jun didn't like to talk to him: "Why not?"
"Ouch...whahahaha..." Li Tai laughed so loudly that his stomach cramped, and he gasped: "You are so childish! Do you think that lighting up a hundred times the ordinary Kongming Lantern will be enough?"
Bring something a hundred times heavier to the sky?"
Fang Jun raised his eyebrows: "Isn't it possible?"
"Oh my god, I'm laughing so hard..." Li Tai finally stopped laughing, pointed at Fang Jun and said, "Is your brain broken? A person weighs hundreds of pounds. How do you expect the Kongming Lantern to carry you?"
God?"
It cannot be said that Li Tai has little talent and knowledge, it can only be said that he has little knowledge.
How could something as simple as a Kongming Lantern carry a person to heaven? This is an inherent impression in the minds of people of this era.
Natural science is about showing miracles in places that people think are impossible.
In contrast, Liu Laoshi and Wang Erxiao, who have already accepted that Fang Jun always turns decay into magic, are already more knowledgeable than the quick-thinking Li Tai.
Fang Jun had an idea: "How about... Your Highness, how about making a bet?"
"How to bet?"
"Let's bet on whether this sky lantern can take people to fly into the sky. If it can, naturally the humble minister will win. If it can't, then His Highness will win. How about that?"
Li Tai rolled his eyes: "Then we have to add some bonuses, otherwise it will be boring?"
"Your Highness, what suggestions do you have?" Fang Jun said matter-of-factly.
"Well... money is a vulgar thing, but this thing is really attractive to people. I bet 10,000 coins. I wonder what Erlang wants?"
"It's a deal! In half a month, the test will be held on the open land at the back of Lishan Mountain!"
"It's hard to chase the horse!"
Li Tai and Fang Jun high-fived and agreed, and left happily.
Fang Jun glanced at Li Tai's plump figure strangely. Is this guy so confident that his hot air balloon can't fly?
Why are you so happy? It’s weird...
No matter what, is it possible that my brother’s college-level physics level can’t make a hot air balloon?
"Did you two see it? Ten thousand guan! Work hard for me. If you win, you will be rewarded heavily. If you lose, I will buy both of you to pay off the debt!" Fang Jun said fiercely.
"No!" Liu Laoshi and Wang Erxiao were really joking, but they were also secretly cruel in their hearts. It could be seen that Erlang was quite at odds with His Highness the King of Wei, and Erlang must not be allowed to lose face in front of the King of Wei!
The two of them said goodbye together and went back to prepare parts for their own businesses.
Li Tai returned to his residence excitedly, called his cronies over, leaned on the desk and quickly wrote a bunch of invitations, and said: "Send these invitations out. If they are full for a while, it will waste my money, and you will enjoy it!"
"
"No!" The henchman took the invitation and ran out in a hurry.
Li Tai touched his bare chin and laughed proudly.
Fang 2, Fang 2, do you think you tricked me, Li Tai?
