"Husband, you have been sullen in the past few days, but what's on your mind?"

At lunchtime, Princess Changle asked in a whisper.

"It's nothing, I'm just thinking about some problems, Datang doesn't seem to have anything new for a long time."

Zhao Yin casually explained, although his shock value at this time was already enough for him to use, but he still enjoyed the pleasure of the rising numbers!

"Husband, what are you going to invent this time?"

After hearing this, Princess Changle suddenly became interested.

Every time my husband comes up with something, the world will be shocked and yearning.

"Hmmm! Just get a little gadget and have fun! Also to make it easier to go out in the future! ”

He's already figured it out, and this time he'll get a bicycle to get around.

Although I once longed for the picture of riding a horse and galloping, everyone who really rode it knew that it was very cool when riding a horse, but after getting off the horse, the hip bone was extremely uncomfortable.

Even if he had made the carriage extremely comfortable, but this speed really made him dare not compliment!

"Isn't the carriage already good?"

Princess Changle looked at him suspiciously.

The carriage of the Horse Mansion, its degree of comfort, made his father red, and the entire Tang Dynasty was the only one, but he didn't expect that the husband was still not satisfied with this.

"Sister, don't you know your husband yet? What he came up with is not something we can imagine at all, let's wait and see! ”

The eldest grandson, Yujia, understood what Zhao Yin meant.

Although the curiosity in her heart is no less than that of the princess, she will not ask, because of academic problems, even if the husband explains more, I am afraid that their understanding is limited, and it is better to wait for the result directly.

"Yu Jia is right, you just wait to see the finished product, this horse will go to draw the drawings first!"

After finishing speaking, Zhao Yin directly put down the dishes and chopsticks, turned around and went into the study, and began to sketch.

With the current technology, it is undoubtedly a bit fantastical to want to directly develop a variable speed bicycle, so the bicycle he wants to study is the most primitive big two-eight!

"Master Horse, I don't know what you ordered when you called the lower officials?"

Lin Wu, who had been busy with the finishing tasks of the driving school, was suddenly summoned here, which couldn't help but make him puzzled for a while.

"How about this?"

Zhao Yin didn't talk nonsense, and directly handed the drawings to Lin Wu, and then sat aside and waited.

"Master Pony, what is this? Why only two wheels? ”

The drawings were very simple, just a shelf, with two wheels installed in the front and back, and it looked unusually thin, and he really couldn't think of what use this thing could be.

"The horse named it a bicycle, and used it to travel much faster than a horse-drawn carriage! And it's so compact that it's perfect for driving on the streets! ”

Zhao Yin explained softly, constantly explaining the benefits of this thing.

"Master Pony, but this thing is only two wheels, is it really safe?"

Lin Wu looked puzzled.

The drawings can be used to understand the use of this so-called bicycle, but he is really not sure that this thing will be safe.

"This thing is actually very simple, the focus is on everyone's sense of balance, look at the bottom of the handlebar, this is the brake, use it to control the speed of the speed, but also the guarantee of safety."

The speed of the bike is not particularly fast, and there are brakes, so it is very convenient to control the speed.

"I see!"

Although there were still doubts in his heart, Lin Wu didn't dare to have too many doubts, and everything was still decided after he studied the bicycle.

"If there's nothing to do, you can go back and research."

"Yes! Don't worry, at least three days, more than five days, the next official will definitely study the bicycle! ”

It's not the first day of studying things with drawings, and if he can't even figure it out, he won't have to mess around.

"Good!"

Zhao Yin is still very satisfied with Lin Wu's commitment.

He also believes that Datang's current technology, in three days, it is not a difficult thing to make a bicycle.

Although he invented several inventions that shocked the world in Datang, this system undoubtedly made him the first king of Datang.

Now Li Er feels that Datang is strong, and there is a faint intention to compete with him for the title.

If there is no assistance from the system, maybe he will give this title with both hands, but for the grand blueprint behind him, this title, he can't let go, God knows if it will bring him another surprise after the shock value reaches a certain level.

If you want to scare yourself with money, it's really a mistake in his calculations, if you want to make money, a little gadget that you can study at random is enough to marry a princess.

He just showed the old boy that money was just a number to him at any time.

If you want to protect your daughter, it's better to have a proper attitude, he Zhao Yin, don't accept threats!

……

Two days passed in a blink of an eye, and early in the morning of the third day, Lin Wu pushed his bicycle to the Horse Mansion under the surprised eyes of everyone.

"Lin Wu, what are you, it's so weird!"

For the people in the entire Pony Mansion, Lin Wu is definitely a frequent visitor, because every time the Pony studies something, he can't do without his help.

"Her Royal Highness Princess Qiyu, this is called a bicycle, and it is the latest research of the master of the horse!"

Lin Wu hurriedly saluted, and then replied respectfully.

For this thing, he had already tried it secretly when he came, and if he hadn't reacted quickly, he would have fallen down many times, so he didn't dare to try it again, but honestly pushed it over.

"Really? The husband's new invention turned out to be this, what is this thing for? ”

Princess Changle suddenly looked around the bicycle like a curious baby, full of doubts and puzzles.

"Xiaguan...... I don't know! ”

Lin Wu smiled bitterly.

Master Ma said at the beginning that this thing was used for transportation, but he couldn't figure out how this thing should be used for transportation.

If you push him like this, this is not a substitute at all, but a burden!

"Produced so quickly? Lin Wu, your efficiency is good! ”

At this moment, Zhao Yin walked out, and when he saw the bicycle, his eyes couldn't help but light up.

"Master Horse, forgive the official for being stupid, I really don't understand how to travel on this bicycle!"

Lin Wu hurriedly saluted, and then stood aside respectfully, waiting for the reply of the master of the horse.

"Husband, come on, tell me, how to play with this thing?"

Princess Changle hurriedly greeted her.

She was full of curiosity about this strange thing at this time!

Zhao Yin reached out and touched the handle of the bicycle, and then began to look at the tires, chains, and brakes, which were basically the same as those of later generations, and he couldn't help but sigh with emotion in his heart.

"Keep your eyes open!"

After slowly putting away his thoughts, Zhao Yin took a deep breath, and as soon as he stepped on the pedal, a familiar feeling instantly surged all over his body.

With a slight force under his feet, the bicycle suddenly drove forward, and Zhao Yin also stepped on the pedal with his other foot and kept pedaling.

Kicking 125 really cooperated with him very much, and in the shocked eyes of everyone, Zhao Yin rode a bicycle and drove around the villa quickly.
