Human beings have developed for thousands of years, and since the word life was born, there have been many controversies.

This word has a lot of meanings! Different people have different understandings of this.

Many people don't understand why they are born and what they live for. It's a big topic that has been talked about for thousands of years.

Live because of life, live because of ideals, live because you love people, live because of loved ones, live because of ......

All this, all kinds of reasons!

Ding Yi now feels that he is alive because he is going home, and he is going to keep fighting and fighting!

It's something on his mind! And at the moment, he is worried about money!

The Musical Instrument Workshop now makes drum kits and guitars. Only the piano is still a little hot, and some connected places are not handled well, resulting in no sound or strange sound.

Ding Yi didn't have much to do about it, the drawings were given, and if he couldn't do it, there was no way.

The singers have also learned stave notation now, and some of the tunes that Ding Yi has taken out have become more and more proficient. A few days ago, I asked some people who sang better to sing a cappella on Chang'an Street, and the effect was also good. It's time to kick off the concert!

……

And when Ding Yi was about to go out, an uninvited guest came.

Ding looked at the eager Li Tai, the kid who had recently become obsessed with mathematics. In the days when Ding Yi was away, he took away a good maid in mathematics in Ding's family. Now, the maid can't satisfy him anymore!

"His Royal Highness King Yue, what is there to talk about when I come back! All right? Ding Yi discussed with Li Tai.

Li Tai dragged Ding Yi's arm, he was also very helpless, it didn't have much effect on this person's identity as a prince, you didn't see that he and Li Er were very presumptuous!

"No! If you don't teach me today, I won't let you go! ”

After all, others are princes, so they can't give too much face. Leaving a one-dimensional quadratic equation, Ding turned around and left.

As soon as he walked to the gate, he saw Li Chengqian at the door, and Wen Qiang was receiving his servants. Just as he was about to go in to report, Ding Yi came out.

The owner of his own family is so popular! King Yue and the crown prince have visited one after another!

"I've seen His Royal Highness the Crown Prince!" Ding Yi still talks about some rules.

Li Chengqian pretended to be an adult and said: "Marquis Shiping doesn't have to be polite, Gu took the liberty to visit today, and I ask Marquis Shiping to forgive me!" "Empress Li Chengqian, the eldest grandson, had a long talk for a night, and Li Chengqian had to accept the reality.

Ding Yi replied: "It's okay, it's okay, I don't know what His Royal Highness the Crown Prince is doing today?" ”

"It's fine, it's just the boredom of being alone in the palace and coming out today to breathe."

"In this case, the minister is preparing to go out, why don't His Royal Highness the Crown Prince go with the minister?"

"It's good!"

As long as Ding Yi does not enter the palace, he will go out with one of the three small ones. You can't keep them at home and get bored!

Today it was Dick's turn to accompany him, and the well-behaved Dick obediently followed behind Ding Yi, taking small steps happily. Dick, who is now half a year old, is a little more than two feet tall and a little more than two feet tall. It doesn't look as cute as it was when I first arrived, and it's already a bit fierce!

"Shi Pinghou, I don't know what breed of dog you are? Why does it look so powerful? Li Chengqian noticed Dick and immediately asked Ding Yi. Find something to talk about, or it's a little embarrassing! He didn't know what Ding Yi was thinking, but he saw him walking with his head bored. I don't know where to go!

Ding Yi was thinking about how to make the concert an instant hit at this time, so he didn't pay attention to him. Hearing Li Chengqian's question, he replied: "This is a shepherd dog!" ”

"Oh? Sheepdog! Can it herd sheep? Li Chengqian wondered.

"It won't, it will!"

Ga...... How do you let me pick up !!

The two are not on the same channel, and they are also talking about each other. After a while, he arrived at the Pegasus Workshop, and Ding Yi asked Li Chengqian: "Does Your Highness know about bicycles?" ”

"There's a custom-made one in the Lonely Palace, but it's not very ridden!"

"Oh! Then His Royal Highness the Crown Prince can come in with me and have a look! See how this bike is made! ”

Ding Yi didn't care about him after speaking, and walked into the workshop by himself. Today, the workshop has expanded considerably, and there are more than 500 craftsmen. The daily production has reached 300 vehicles, and there is a team dedicated to improvement.

When I entered the office, I saw Li Siwen drawing something, this kid is now so obsessed with machinery!

"Siwen, don't look at it! Good stuff for you! Ding Yi called.

"Ahh Ding Yi, you're here! ”

"I've seen His Royal Highness the Crown Prince!" It was Li Chengqian who saw Ding Yi again.

"Siwen doesn't have to be polite!"

Li Siwen was not pretentious, and directly dragged Ding Yi and asked, "What did you bring?" Take it out! ”

Ding Yi took out a wad of paper from his pocket, on which were all kinds of things hung.

Skateboards, strollers, unicycles, scooters...... There are many kinds of them, all of which Ding Yi painted according to the way he remembers.

"You can make all these things out in one way, and make some small ones for the bicycles, and put two small wheels on the side. Ride for kids! ”

Ding Yi pointed to the drawings and explained to Li Siwen one by one, used on the construction site, ridden by children, and used for playing.

Li Siwen heard it in a fog, and he also understood something. Recently, some people in Chang'an have begun to imitate bicycles, but the effect is not good.

Now there are so many more styles, which makes Li Siwen's eyes light up, his mind opens, and he also points out some things that can be improved! Ding's hand-painted kung fu is still a little worse.

Ding Yi asked, "How is the tricycle doing?" ”

"The problem with the rear wheel of the tricycle has been solved, there will be no more breakage, and the bike has added brakes as you said, but there is no suitable material. The cost of replacing it with animal fur is too expensive and not cost-effective! Li Siwen replied.

Ding Yi thought for a while and said: "Then make it clear to them, there will be an additional charge for installing brakes, otherwise there will be no brakes." ”

Li Chengqian heard it next to him, and immediately felt that he had been deceived, and it turned out that the custom bicycle he bought was still a defect! So what are the brakes for?

"Shi Pinghou, what is this brake?"

The prince asked, and Ding Yi gave him a general explanation. Li Chengqian instantly thought of the fact that he had been thrown several times because he was riding too fast, you black-hearted businessmen!!

Ignoring the sulking prince, Ding Yi followed Li Siwen to see the tricycle.

It is very similar to that of later generations, except that there is no rubber. Everything seemed so harmonious, Ding Yi rode up and tried it. It works great!

"Your Royal Highness the Prince, let your servants pedal the tricycle, and the three of us will sit in the back compartment and try to bear the load!" Ding Yi said.

Li Chengqian also looked curious, this thing with one more wheel than a bicycle looks very interesting.

The three of them sat in the back, and Li Chengqian's servants in front of them pedaled quite easily. Let me continue to be a master!

After some testing, it can withstand a weight of 500 catties! Any more will deform!

After chatting with Li Siwen for a while, Ding Yi took Li Chengqian away!
