Lan Yu is indeed a little smarter, but he still can't figure it out, what way does Liu Chun have to send people to the sky? Doesn't it depend on blowing?

It really made Lan Yu cloudy, and Liu Chun was studying, how to blow!

A mature hot air balloon can even do a flight across the ocean, Liu Chun didn't even think about it, and directly vetoed it. He didn't even plan to let the hot air balloon fly, as long as it could be sent straight into the air, he could burn high incense.

Tao Chengdao heard Liu Chun's plan, he was a little disappointed, in this Mr. Tao's heart, it is best to fly like a bird, that is the coolest.

Liu Chun said helplessly: "Mr. Tao, let's do it, let's get the hot air balloon out first, and then I'll draw you a map of a gliding wing, you can build it, find a steep cliff, and you can fly like a bird." ”

"Really?" Tao Chengdao asked in surprise: "Can it really be done?" ”

Liu Chun nodded, "Swear by my ancestral master, I promise to do it!" However, the glider is dangerous, so it cannot be used by nobles. ”

"I'm not afraid!"

Tao Chengdao is an iron man, he even dares to sit on the rocket chair, what else is there to be afraid of.

He suddenly became interested, "Lord Liu, who is your ancestral master?" Have you heard of it? ”

Liu Chun shrugged his shoulders, "Guo Shoujing of the previous dynasty, you always know, right?" ”

"What?" Tao Chengdao's face sank, and he said in a sullen voice: "He, he works for the Tartars!" ”

Liu Chun said calmly: "That's right, he is indeed an official of the previous dynasty, so I have never liked his character very much." ”

"Then, why are you still worshipping at his door?"

Tao Chengdao can't even turn around, he goes straight and straight, which is very in line with the virtue of the old otaku of science and technology. Liu Chun didn't care either, and laughed: "Are you willing to do it?" They instilled a lot of stuff in me without my consent, and in fact, when I was studying, Guo Shoujing had already died, and it was his disciples who taught me. Also, there is no need to despise human character, at least what they have given me, so far, there is nothing wrong! ”

Tao Chengdao took a breath, seemed to have an understanding, and nodded slowly, "Zhu Xi said that there is a reason in the world, I also think that there is a reason in the world, but it is just different from him, but I can't say it well!" ”

"Our teachers call it truth, or natural science!"

"Natural sciences?"

"Yes, natural science emphasizes that one is one and two is two, and there is no such thing as inexplicable nonsense. We explore the knowledge that exists between heaven and earth! ”

Tao Chengdao listened, and suddenly looked excited, feeling that what Liu Chun said was very agreeable, and there were many coincidences with his decades of exploration.

"Liu, Lord Liu, I wonder if Xiao Lao'er can learn this knowledge?" Tao Chengdao said boldly.

Liu Chun smiled happily, "Of course you can, I'm too much to learn, and I just need someone to help me carry it forward!" ”

Tao Chengdao got a positive answer, and suddenly he was overjoyed, he jumped and jumped like a child...... disappeared in a blink of an eye, Liu Chun was puzzled, and said in his heart, is this guy crazy?

After almost a cup of tea, Tao Chengdao came back again, followed by dozens of black guys...... These people are generally thin and withered, their faces are tanned and red, their bodies are skinny, there are not a few taels of flesh, but their eyes are quite bright and very energetic.

Tao Chengdao said happily: "Hurry up and kowtow to Lord Liu, what's it called?" ”

This one didn't even think about it, he looked at Liu Chun in embarrassment, "Lord Liu, you see that they are all my disciples, are they called Master Da, or Master ......?"

Liu Chun couldn't cry or laugh, "Master doesn't need to be called, Master doesn't need to be called, Master doesn't need to, they are still your apprentices, I, I'll just teach you the knowledge!" ”

"That's not going to work!"

Tao Chengdao thought about it, and suddenly knelt on one leg, "Tao Chengdao to meet Senior Brother!" ”

He bowed to his senior brother, and the rest of the boys immediately knelt down, calling Liu Chun a master, that is simply a one!

In fact, many people are older than Liu Chun, but the seniority is there, and they can't help but kowtow.

Liu Chun was also quite helpless, so he could only accept it. He inquired carefully, and then learned that Tao Chengdao studied firearms, and many children of craftsmen in the army worshipped him as a teacher.

If it is peaceful today, there will be fewer places for these people to show their strength.

Tao Chengdao devoted himself to studying Feitian again, constantly fiddling with gunpowder. This guy has had several accidents, destroyed all the neighbors' houses, and lost a lot of money.

There was no way, Tao Chengdao could only move to an open place outside the city, away from people's homes, and continue to experiment. The disciples also left quite a bit, and there were only a few dozen left.

Originally, Li Wenzhong was willing to help him, but after Li Wenzhong's death, Tao Chengdao could only rely on the court's money, but Zhu Yuanzhang's money was notoriously low, and he was obsessed with research, didn't know how to manage money, and lived a tight life, eating the last meal but not the next.

If the master mixes this virtue, the disciples are no better.

The reason why Tao Chengdao is actively planning and wants to experiment with flying is also to become famous in one fell swoop, the court has a reward, and the disciples can have a better life, and they don't have to be like monkeys.

Lao Tao said that he had no intention, but Liu Chun listened intentionally.

Life is so hard, and you can still follow the left and right, these boys are either stupid or stupid! Fools can do things, stupid people can't do bad things!

In Liu Chun's eyes, they are all treasures, as long as they are trained a little, they can ignite the fire of science in Daming, and finally spark the prairie fire!

But before you can achieve a great goal, set a small goal, for example, to get the hot air balloon flying.

Liu Chun discussed with Tao Chengdao, the structure of the hot air balloon is not complicated, first of all, it is a huge air bag.

"This must be made of the densest and strongest silk, sewn carefully so that it does not leak."

Tao Chengdao nodded, "No problem, this is not difficult, it's just, it's just ......"

He swallowed, but Liu Chun smiled, "It's just a lack of money, right?" It's okay, let's get 10,000 yuan first! ”

"Ten thousand?" Tao Chengdao was stupid, and hurriedly waved his hand, "It's too much, it's too much, it's almost like 500 guan!" ”

Liu Chun smiled: "More is more, the extra is the red envelope given by my uncle, let the big guy change into new clothes and eat some meat, we are skilled workers, we can't be too shabby, right!" ”

As soon as these words came out, these disciples of Tao Chengdao simply threw themselves to the ground, uncle, you are simply a living Bodhisattva!

Master has persevered for so many years, and finally waited for the opportunity! The heavens have eyes!

These boys held their heads high and went to buy it immediately.

Next is the hanging basket, this is easier, Tao Chengdao is very handy, he usually makes up chairs.

"The most important thing left is the heating device, especially the fuel, I originally wanted to use the fierce fire oil, but the smoke of the fierce fire oil is billowing and the effect is not good. Do you want to refine some oil? ”

Liu Chun muttered to himself, and quickly denied it, after all, relying on the soil method to heat, can he make qualified kerosene, he expressed strong doubts, Zhu Yuanzhang was too urgent, and there are so many vassal states, once there is an accident, he will become a sinner, and no one can save him.

"Senior brother, I have a proposal, but it's a bit expensive!"

"Expensive? What are you afraid of, anyway, it's not me who pays for it! Liu Chun encouraged: "Speak, if you have any good ideas, just say it!" ”

"Senior brother, do you see if you can use some kun oil?"

"Kun? What kun? Liu Chun's mind flashed a pretty figure who could sing, dance, rap, and basketball......

Tao Chengdao said patiently: "It is a big fish in the sea, fishermen call it kun, and the oil of kun can be used to light lamps." ”

Liu Chun suddenly realized, "It's whale oil!" Right! Just use whale oil! ”

Tao Chengdao said worriedly: "Senior brother, Kun oil is not cheap, and the sea has been banned for many years, and the fishermen are gone, so you must find the sailors in the court to ask for it, maybe it will alarm Your Majesty!" ”

"Alarmed, alarmed! Anyway, if it's for him, can he still help? Liu Chunman didn't care, he didn't even understand why Tao Chengdao was so afraid of Lao Zhu!

Liu Chun thought about it, the airbags, hanging baskets, fuel, all have eyebrows, and there are dozens of capable craftsmen, there is no reason why the hot air balloon can't fly.

Since I was able to fly there, this was the most important first time......

Liu Chun thought about it again and again, "Lao Tao, do you think we can have another auction and let the big guy pay for the opportunity to buy the heavens!" This is the first time ever! Would it be worth a lot of money, you say? ”

Tao Chengdao rolled his eyes directly, "Senior brother, what are you learning?" Could it be that you can't make money? ”

"What? No! ”

Liu Chun said angrily: "You are old, you have to think about it for your disciples, don't make more money, how can they marry a daughter-in-law?" If there is no daughter-in-law, where is the child, if there is no child, who will inherit the craft......" Liu Chun hated that iron could not become steel and said: "So, if we are engaged in science, we must first learn to make money!" ”
