When Yu Zhiqian found Cheng Chumo, this guy was outside the city, ready to experiment with his latest research on the flying machine, the last time it failed, it has only been a few days, and this thing is unstable again!

However, if this kind of flying test is not handled well, it may cause death, although Yu Zhiqian is not a virgin, but he can't be silently from Cheng.

However, when Yu Zhiqian saw the flying machine in front of Cheng Chumo, the whole person was stunned, if it weren't for the fact that the onlookers around him were wearing ancient costumes, and a group of people shouted His Royal Highness the Prince, Yu Zhiqian was a little suspicious that he had traveled back.

"His Royal Highness the Crown Prince!"

After Cheng Chumo saw Yu Zhiqian coming, he had a smile on his face and wanted to ask for credit, and at the same time, his small eyes kept looking back, and after making sure that he didn't see his sister, he breathed a sigh of relief.

"What are you looking at?"

"I thought my sister was here, and when I was doing the test before, my sister knew about it, but she chased me and beat me, and the last time I was found out, I heard that she was looking for me!"

"Don't worry, your sister was coaxed by me, she didn't come over, you have this heart to explore science!" Yu Zhiqian praised Cheng Chumo, the most important thing in doing scientific research is to have a heart of exploration, and it is obvious that Cheng Chumo has this heart.

However, Yu Zhiqian always felt a little sorry for this guy, he will be a generation of famous ministers or famous generals in the future, but when he comes to himself, I don't know what will become of him? A science maniac? One of the founders of modern science? It doesn't seem to be bad, either!

"His Royal Highness the Crown Prince Xie, His Royal Highness the Crown Prince, this is the flying machine that I researched together with Li Bai and others, what do you think?"

Yu Zhiqian glanced at the flying machine in front of him, how to say it, it was very similar to a modern glider, but the material was much heavier than the modern one.

Yu Zhiqian walked in front of the machine, looked at the flying machine in front of him carefully, and nodded slowly: "It looks good, how did you come up with it?" ”

"Drag Your Highness's blessing, I thought that if people want to fly, they need to have wings like birds, but we don't have wings, so I made one!"

"Then I had people jump down from the height with the big wings I had made on their backs, but the man was too flustered to shake his wings, so he fell, and then I jumped down from the height, and found that even if I swung hard, I couldn't fly, but I slowed down the fall, so I ....... again."

Cheng Chumo excitedly introduced his invention, and Yu Zhiqian also understood that this guy's inspiration came from the last time he fell from the stairs.

Yes, that's right, it was the time when Cheng Chumo fell from the stairs on the opening day of Tsinghua Park, I have to say that there is a certain number in the dark!

"And then?"

"Then I invented a bigger one, and I ran down the high slope, and I felt that my feet were off the ground, but I still didn't fly, and I thought maybe my material was too heavy, so I improved it again!"

When he said this, Cheng Chumo's eyes burst out: "Your Highness, after I used the new materials, I flew a distance, although it was very short, but it can be proved that what His Highness said is correct, people can fly!" ”

After finishing speaking, he pointed to the equipment behind him: "Later, I improved it again, it is the way it is now, but I am ready to continue to change it, Your Highness, the bicycle you invented is good, if you can add it, even if you add a booster system, the faster you run, the faster you will be able to fly!" ”

Yu Zhiqian nodded, Cheng Chumo's general direction was not wrong, but he was a little curious: "Why did you think of pressing the bicycle?" ”

"I saw some birds, when they fly, they need to run, I thought, birds need to run, so do people need to run, so that's why ......"

Yu Zhiqian listened to Cheng Chu talk silently, nodded slowly and said two words, not bad! It's really good, this product definitely has the potential to be a scientist, the spirit of exploration of scientists, and careful observation, this product has it, it seems that he is not really happy in history!

"Does Your Highness think it's good? Your Highness, do you think my experiment will succeed? ”

Yu Zhiqian looked at this guy, success? Where to go to success, don't you know how to choose a place with a slope, in front of the north gate is a long official road, even if the wind is still quite strong today, there will be ghosts to fly!

"Where around are there long slopes?"

Hearing Yu Zhiqian's inquiry, Cheng Chu was stunned for a moment: "Yes, there is a location called Shilipo in front of me, and there is a hillside, about hundreds of meters!" ”

"Let's go over there and test it!"

"Whoa!"

A few family-like people, dragging Cheng Chumo's glider, and a kind of entourage, rushed towards Shilipo, Yu Zhiqian thought with some curiosity, the place called Shilipo, I don't know if there is a person there, known as Shilipo Sword God!

"Your Highness has arrived!"

Ten miles of slope, ten miles north of the city, from here the terrain began to go down sharply, and a few miles ahead, it is a branch of Weishui, what is the specific name Yu Zhiqian is hungry I don't know, and no one has paid attention to it.

"Well, nice place!"

Today is also God's face, there was originally a light wind of three or four levels, but after arriving at Shilipo, there were roughly five or six levels, and the weather was still a little cold in early spring, plus the wind blew, people couldn't help but shiver twice.

There were a lot of onlookers, some of them were brought by Cheng Chumo, and some of them were the group of noble children in Chang'an City who were full of food and had nothing to do, and they also joined in the fun, and some of them were people passing by, but they were all onlookers and didn't dare to get too close.

The biggest head is still Yu Zhiqian's guard, now Yu Zhiqian is in charge of the country, although he is still the prince, but his status has changed dramatically, so Yu Zhiqian is now traveling, and there are more than 200 people on the surface of the guard, and I don't know how many there are secretly, Yu Zhiqian turned his head to look at the forest in the distance, there are faintly many people.

"It's good here, who do you let test fly?"

Although Yu Zhiqian was not too optimistic about this flight plan, he still insisted on letting Cheng Chumo give it a try, failure is not terrible, what is terrible is that he does not dare to try, what if Cheng Chumo succeeds?

Cheng Chumo asked people to push the glider out, and then pointed to a very thin guy next to him: "His name is Zhang San, I bought it from Dongshi Lingxing, his body is thin, but he has a little strength!"

Yu Zhiqian looked at it and nodded, it really needs a thin person, this Zhang San looked at Yu Zhiqian a little nervous, his main status was terrifying, but he spoke respectfully in front of this young man.

No one told Zhang San how big an official he was, but the instinctive Zhang San was a little scared when he saw Yu Zhiqian.

"Ready!"

After Yu Zhiqian finished speaking, he waved his hand, and immediately a guard brought his little horse tie, Yu Zhiqian sat down casually, this kind of little horse za has been very popular since it was invented by Yu Zhiqian, and it is about to sell crazy in Chang'an City.

In the past, when everyone went out, they met and chatted together, chatted and chatted, and when they were tired, the rich people found a tea house, drank tea and chatted, and those who had no money found a corner to sit down and continue to chat, but now it is different, with a small Maza with them, and when they meet acquaintances, everyone will find a corner and sit down and talk directly.

Not only do you not have to spend money to go to some teahouses, but you also don't have to be looked down upon, in addition, when you encounter any bustle, the front row sits on the small horse, and the people in the back stand, so you don't have to be too crowded.

In addition, when queuing, you can also take a small horse at will, don't worry about back pain because of the long queue, and which elderly people used to come out to bask in the sun and sit on the big stone at the door of the house.

It can be said that the advent of Xiao Mazha is the same as mahjong, and it instantly became popular in Chang'an City, and Yu Zhiqian also made a small profit, but soon the imitations came out, not only did Xiao Mazha come out, folding tables and other similar designs.

Getting back to the point, after Yu Zhiqian sat down with a small horse, someone immediately sent a small tea set and a small stove to boil water for Yu Zhiqian to prepare to make tea, while Cheng Chumo was constantly checking his equipment and constantly talking to Zhang San about precautions.

"That Chu Mo, if you fly, how do you land?"

Hearing Yu Zhiqian's words, Cheng Chumo was stunned, looked at his machine, and then looked at Yu Zhiqian: "Your Highness, I really haven't considered this!" ”

Yu Zhiqian glanced at this guy, only thinking about flying, not landing, after all, compared to landing, being able to fly is the supreme glory.

"Forget it, it's okay, just be able to fly, as for landing!"

Yu Zhiqian shook his head, scientific research still has to have the spirit of sacrifice, this Zhang San sold into Cheng Chumo's house, the fate is Cheng Chumo's final say, Yu Zhiqian did not think about overthrowing this system, after all, he is the beneficiary, and he is not the Virgin, if because of a person's death, and bring technological progress to the Yu Tang Empire, Yu Zhiqian is also very willing, it is better than saying that he is self-contained, stops, and is invaded and slaughtered by the enemy many years later.

"Ready!"

"Whoa!"

This Cheng Chumo's glider, although it did not add a bicycle to speed up, but also added small wheels, in this way, it is more effortless to push, Yu Zhiqian definitely did not teach Cheng Chumo to deal with it like this, but he did some things himself, and it is estimated that Cheng Chumo saw it.

"Your Highness, you're ready!"

The guy named Zhang San got under the glider, which was a simple handrail made of hollow bamboo, which could push the glider forward, Yu Zhiqian looked at the potholed ground and shook his head: "Fix the ground a little smoother!" ”

After hearing this, Cheng Chumo nodded, and immediately someone took tools and began to trim the land.

"The next time you build a cement road, the so-called workers must first sharpen their tools if they want to do a good job, you don't even have a complete runway, how can you succeed in the experiment!"

"What is the runway?"

Cheng Chumo touched his head, thought for a while, and was stunned that he didn't think of what Yu Zhiqian's so-called runway was, Yu Zhiqian smiled: "It's a smooth road, I told you, friction, the smoother the road, the more convenient it is to walk, and the more convenient it is for the wheels to roll, understand!" ”

"Understood! It's like walking on an official road and being fast, but walking on a country road or mountain road is slow! ”

"That's pretty much it, but it's too late now, let's take a look at the results of your test this time!"

A group of people worked together to repair a dirt road that was about a few tens of meters long, although it was a dirt road, but it was not like the previous potholes, and all the places with potholes were filled.

After Zhang San was ready, he yelled, and then pushed the glider hard, rushing forward, the glider moved very quickly at first, but gradually after the speed increased, the glider began to slowly float upward, but only a little.

"Get up, get up!"

Cheng Chumo shouted excitedly, Yu Zhiqian looked at the glider that was getting farther and farther away, and roughly understood in his heart that it should have been a failure, the speed was too slow, and if it was a little faster, it might be able to take off successfully.

"Accelerate, accelerate, accelerate!"

Cheng Chumo continued to roar loudly in the back.

"If you fly, I'll reward you with a hundred taels of silver!"

Money is the absolute driving force, since Zhang San can be sold into the shop, he must have sold himself, and he is very short of money, so after hearing Cheng Chumo's words, Zhang San, who had already used all his strength, gritted his teeth and used all his strength to eat, and the speed of the glider was together, the original speed was only five or six per hour, but now there is at least ten!

After Yu Zhiqian heard this, he looked at Cheng Chumo with some curiosity: "You have money?" ”

Cheng Chumo nodded: "Your Highness, since I went to school in Tsinghua Garden, I have been rich, and this experiment is also supported by my family!" ”

"I didn't go to the Qinglou even if I was rich!"

Cheng Chumo leaned on Yu Zhiqian, and then said in a low voice: "If Your Highness wants to go to the Qinglou, I will treat you!" ”

“……”

Sure enough, Cheng Chumo is still the same Cheng Chumo, just because he has a small goal now, and he has not changed in essence, he is still the guy who likes to eat, drink and have fun!

"If you're not afraid of being beaten to death by your sister, you can go!"

After hearing Yu Zhiqian's words, Cheng Chumo immediately shut up and did not mention the matter of Qinglou, for Cheng Chumo, Cheng Xiang is a hurdle that can never be passed.

"Your Royal Highness, my sister is now your side concubine after all, you said that you are the crown prince, and the side concubine often carries a big axe out of the palace when she has nothing to do, which is really a bit ......"

Yu Zhiqian glanced at Cheng Chumo: "Why do you want to manage the family affairs of the palace?" ”

"No, absolutely not, Your Highness, I'll just say it casually!"

While speaking, the glider had already run out of a distance of dozens of meters, and at this time Yu Zhiqian's eyes lit up, and the glider flew up, roughly three or four meters away from the ground, and then began to staggering in the air.
