"Big brother!"

Yu Tai stood behind Yu Zhiqian a little crampedly, wanting to speak, but after thinking for a long time, he didn't know how to ask.

"What's wrong?"

Yu Zhiqian looked at the happy seventh child riding the car, and turned his head to look at the second child, the second child has been a little strange recently, when this guy wants to say something, he won't say it directly, he has to swallow and vomit, Yu Zhiqian can't wait to open his head to see what is inside.

"Big brother, this car, can you tell me about the principle?"

Yu Zhiqian scratched his head and let himself explain the principle, Yu Zhiqian thought for a while, sorted out his junior high school physics data, and slowly spoke: "Do you know what inertia is?" ”

"Huh? Inertia? What is the character that people are accustomed to? ”

The second child tried to explain the literal meaning of inertia.

"Well, you misunderstood, how to describe it, the bicycle forward, part of it depends on inertia, and part of it is the force you give when you pedal, as long as you overcome the friction on the ground, the vehicle will move forward!"

Hearing Yu Zhiqian's words, the second brother was even more confused, and he couldn't understand it anymore, what is inertia, what is friction, Yu Tai felt that today's eldest brother seemed to be easier to speak, it was a good opportunity, if he didn't understand, he had to ask, it was best to ask from his eldest brother's mouth about the car that could move by boiling water, and then study it himself to please his father.

In Yu Tai's eyes, Yu Zhiqian got this bicycle, just to please his father, his eldest brother seems to be unlearned, but in fact, he is secretly currying favor with his father, just look at mahjong, this thing is what he likes, and he is going on a crooked path, and his eldest brother does not dare to compete with himself in a dignified manner!

Yu Tai felt that since his eldest brother could do this, he should not blame himself, and he could also learn to please his father and emperor.

"You said steam locomotive, this thing is honest, it's a little difficult for Datang's technology to come up with now!" Yu Zhiqian touched his chin, the steam engine, it won't come out until a thousand years, and now it's almost impossible to get it out in advance.

"Big brother, my brother is very interested, and my brother can say it briefly, and if my brother is free, you can study it, what if it succeeds?"

After Yu Zhiqian heard this, he was stunned for a moment and stared at his second brother, does this guy want to be a scientist, isn't this guy interested in the throne?

I quickly thought about it in my mind, if I am not the emperor, the second child will be the emperor, and my relationship with him is not very good, if I want to kill myself, where will I reason, if I can fool the second child into a scientist? Then if you support Lao Qi to succeed to the throne and your own brother becomes the emperor, wouldn't your dream of not being the king of freedom come true!

Thinking of this, Yu Zhiqian coughed lightly: "Second brother, do you know why I don't want to be the emperor, eldest brother?" ”

Yu Tai snorted coldly in his heart: "Is your eldest brother going to fool yourself again?" I don't want to be an emperor, I don't want to be an emperor, you go to open a restaurant to gain prestige among the people, engage in mahjong to please your father, don't want to be the emperor to investigate the case, don't want to be the emperor, say that, gather the material resources of all countries, and rejuvenate my Tang Dynasty? Ahh ”

However, on the bright side, Yu Tai still looked at his eldest brother with an open expression: "The eldest brother said that being the emperor is too hardworking, but the younger brother thinks that the eldest brother should not work hard and be wasted, after all, the Tang Dynasty of our Yu family, the eldest brother is the eldest son......"

Yu Zhiqian waved his hand: "Okay, now I'll tell you the truth, in fact, eldest brother, my interest in this world is far more than the throne!" ”

"Big brother, brother doesn't understand!"

Yu Zhiqian patted Yu Tai on the shoulder: "Second brother, let me ask you a question, why did you say that if the apple was ripe, why did it fall to the ground?" ”

"The melon is ripe and landed, this is a normal thing!"

"Then why did you drop a stone to the ground when you threw it into the sky!"

"It's because you didn't use any more force, so it fell to the ground!"

Yu Zhiqian smiled mysteriously: "The kite, no, should the paper kite be able to fly in the sky?" ”

"Because, because, because there is wind, the wind blows the paper kite!"

"Then why can't the stone blow?"

"The stone is heavy!"

Yu Zhiqian nodded: "What you said is right, but it's not right!" ”

"Please make it clear!"

At this time, Lao Qi also walked over with a curious face, and threw a stone into the sky, and finally fell to the ground, and suddenly asked with some curiosity: "Big brother, why did the stone fall, it was obviously windy!" ”

"Because of gravity!"

"Gravity?"

"Yes, gravity, we can walk on the land because there is gravity!"

“……”

Both of them were stunned for a moment, not understanding what this meant.

"Everything makes sense, this is what our ancestors told us, you observe more, do you see why a dry leaf can float up, but if it is wet, it can't float?"

"Why?"

Yu Zhiqian was asked, he really didn't know, but he must pretend to be forced to the end: "This needs you to discuss, when you discover these truths, you will find that a new world is opening up to you, you will find that you are too small, there are countless funs behind the door, why Bengong was able to invent bicycles, why can I invent mahjong, it is because Bengong saw it!" ”

"Big brother, then you said the car burned with water......"

The second child suddenly reacted that he was here to ask about the car that boiled water, not a matter of force.

"Er, have you ever boiled water?"

"Huh?"

The second child thought for a while and shook his head: "It hasn't been burned!" ”

Isn't this nonsense, how can a prince go to boil water in person, eat and drink every day, and the people below serve him well.

"You go back and boil the water, put a lid on the teapot, and when the water is grilled, you will find that the lid will be lifted!"

"Huh? Are you sure? ”

"Yes, you can try it, but the lid must be light, if it is too heavy, the steam will not be able to bring up the lid, and when you figure it out, you will know what I said about the car that boils water!"

Although Yu Tai didn't know very well, he still left in a daze, Yu Zhiqian looked at the direction of the second child and smiled mysteriously, this guy went back to do an experiment, and then became interested, and devoted himself to scientific research in the future, thinking of this, Yu Zhiqian couldn't help but feel a little black.

But for the sake of your dreams, you should be a great scientist, maybe the introduction of Baidu entries in the future will say, Yu Tai, an ancient inventor, can be regarded as famous in history!

The seventh man beside Yu Zhiqian, after listening to Yu Zhiqian's words, thought for a while and slowly spoke: "Big brother, I have seen people boiling water, and the lid seems to have been lifted up, what is this for?" ”

"I'm rubbing, why are you asking this, children study hard, don't think about these messy things, only people like the second child will study these things, you go to school well!"

Hearing Yu Zhiqian's words, Lao Qi looked at Yu Zhiqian with some anger: "Big brother, are you okay!" ”

"Hey, the eldest brother doesn't know, the eldest brother just found it by accident, he just thinks it's very interesting, if this power is used for other purposes, such as pulling a cart? However, these things require the accumulation of knowledge, and you need to study hard now to be able to figure it out later! You see, big brother, I just didn't study hard, so I didn't understand it! ”

After Yu Zhiqian finished speaking, he spread his hands, he really didn't know, the steam engine, how much scientific knowledge was needed for this thing, he was in love when he was in school, playing games, when did he study seriously.

If Yu Zhiqian can go back to the past, in the case of knowing that he will cross, he must learn Yun Ye well, know a little bit of everything, or bring a few encyclopedias!

"Okay, big brother, that brother has retired!"

Lao Qi's eyes flashed, and he slowly said to Yu Zhiqian, ready to leave, but when he looked at Yu Zhiqian's bicycle, he was a little reluctant.

"Don't look at it, when I research something that can be mass-produced, I'll give you one, this thing is the first sample car, and I want to improve it!"

"Thank you, big brother!"

After Lao Qi finished speaking, he quickly left with his guards, and the first thing he did when he went home was to study the teapot.

After Yu Tai left, he quickly rushed towards his palace.

"Your Highness, are you not entering the palace?"

Yu Tai waved his hand: "Don't go for the time being, go back to the house!" ”

Yu Tai, who returned to the mansion, did the same thing as Lao Qi, and about a quarter of an hour later, the two of them stared at the teapot lid that was filled with steam in mid-air.

"Zhou Yu, how did you say that the lid of this teapot was lifted!"

Zhou Yu, who was about more than two hundred pounds covered in muscles, reached out and picked up the lid directly, and then retracted his hand after being burned by steam: "Your Highness, it should be this hot gas!" ”

"Hot gas?"

Lao Qi began to think about what his eldest brother said, what method should be used to convert the power that can lift the lid to other places?

At the same time, the second Yu Tai also fell into this predicament, and the two of them began to scratch their ears and cheeks to think.

Yu Zhiqian pushed his bicycle into the mansion, and Zhang Zhan trotted to Yu Zhiqian's front and asked in a low voice: "Your Highness, what about those girls in Fengyue Xiaozhu?" ”

"Huh? I almost forgot about this stubble! Yu Zhiqian patted his head, this group of women is still in the East Palace, if the case has not been solved before, this group of women is clue to stay in the East Palace!

But now that the case has been closed, it is indeed a little inappropriate for these people to stay in the East Palace, Yu Zhiqian resisted the urge to open a Qinglou by himself, and thought for a while: "In this way, the Qingqi people inside will be left in the East Palace to be singers, as for the other women, let them all go, by the way, the drug-addicted woman will be thrown to Jinyiwei and forcibly detoxified!" ”

"Whoa!"

"Your Highness!"

The matter on this side had just been dealt with, and on the other side, Shen Wansan ran over panting: "Your Highness, the things for the great sacrifice have been prepared, Your Highness, you can take a look!" ”

"Ready?"

"Yes!"

The triennial festival and the ten-year ceremony are all torture for the current princes and ministers, including Yu Zhiqian, but there is no way, no one dares to break the rules handed down by the ancestors.

"Your Highness, that's it!"

Shen Wansan took Yu Zhiqian to the side hall, a flat pole, with five grains in it, Yu Zhiqian tried it with his hands, and his face turned green at that time, these things add up, at least forty or fifty catties, and he has to carry it for ninety-nine miles, isn't it to die of old age?

"Why is it so heavy?"

"Your Highness, you are the crown prince, and there are also His Royal Highness and the queen's mother, and you also have to lead a sheep!"

“……”

Yu Zhiqian can now imagine that in the picture three days later, he will have to carry these things on his shoulders, and then lead a sheep to walk in front of the team, not ninety-nine miles, only nine miles, Yu Zhiqian is estimated to be half tired to death.

"Don't you need a carriage?"

"Your Highness, you can't use a carriage, you can only use manpower, you can also push a small cart, but the carts are all used for mud legs, you are a prince, your status is noble, it's better not to use it!"

“……”

Yu Zhiqian stared at these things, and tried again, with his own ability, if he forcibly carried it over, he could indeed get there, but people would basically be abolished, so he needed to think of a way.

"Your Highness?"

"Wansan, what did you say before?"

"Your Highness?"

"No, the previous sentence!"

"Before?" After thinking for a while, Shen Wansan asked a little uncertainly: "Your Highness, you don't need a carriage, you can only use manpower, you can also push a small cart, but the small carts are all used for mud legs, you are the crown prince......"

That's it, you can use manpower! You can use manpower! ”

Yu Zhiqian's eyes lit up, didn't he have researched a bicycle, you can ride this thing, thinking of this, Yu Zhiqian rushed out: "Wansan, carry out the things you have prepared, I'll take a look!" ”

"Whoa!"

Shen Wansan carried the grains and some things to the yard, only to see Yu Zhiqian push the bicycle over, looked left and right, and then said, "Wansan, you go and prepare a few bags and pack these things separately!" ”

"Whoa!"

Soon, the things that were packed separately were tied to the back of the bicycle by Yu Zhiqian, Yu Zhiqian held the already heavy bicycle, took a deep breath, pushed hard, and then prepared to jump on the bike.

It's a pity that this bicycle is like a bicycle plaything, a person can ride hard, but dragging dozens of pounds of things, the huge resistance directly makes it almost difficult for the car to move forward!

"Your Highness!"

After seeing Yu Zhiqian fall, Shen Wansan and the others immediately rushed over.

"I'm fine!"

Yu Zhiqian got up from the ground and looked at the car on the ground, the bicycle is definitely not good, he must have a way, as a good young man in the 21st century, he must use his brain to solve the things that can be solved, and absolutely do not use brute force!

"What should I do?"

After Yu Zhiqian circled around the bicycle, he suddenly had a magical idea in his mind, and then clapped his hands vigorously: "There is!" ”

"Zhu Youxiao, Zhu Youxiao, go and find Zhu Youxiao for me, by the way, find a few blacksmiths to come over, find a good technique, go to the Ministry of Industry to find it, just say that the palace is in urgent need!"

Bicycles can't hold things, but tricycles can, and the technical difficulty of tricycles is similar to bicycles, mainly gears, chains, these things can be replaced by things, and it will definitely be much better than carrying them on your shoulders!
