At this moment, a thunderstorm suddenly came, and the sky seemed to leak, and the rain fell from the sky, and before people could react, the uncovered place was instantly covered by the water curtain.

In a daze, the three of them were trapped in the pavilion.

Fortunately, there is nothing else to do. The three of them were stunned, looked at each other, and then they all laughed before continuing the topic just now.

"By the way, what do you mean by what you just said?" Judy thought for a moment and looked at Jiang Chao in confusion.

Jiang Chao paused slightly, his expression was calm: "We may be able to think differently." The point of restricting shared bicycles that Judy just mentioned is actually rooted in the contradiction of returning bicycles at a fixed location but an uncertain riding trajectory...... Wouldn't this contradiction be resolved if there is no fixed place for return?"

Judy was stunned, "But what about ...... So how does that work?"

"Just lock it up. Jiang Chao smiled lightly.

But before Judy could speak, Dong Chu had already frowned: "How can the person who borrowed the car obediently lock the car?"

Jiang Chao knew that Dong Slow and Judy couldn't figure it out for a while, because their thinking was still stuck in the shackles of traditional shared bicycles, and the ideas that radiated from there couldn't get out of the traditional form.

And what Jiang Chao has to do is to rake the shackles on their thinking. Just now, when Jiang Chao was thinking about shared bicycles, a lot of messy inspirations jumped into his mind, which came from his long-standing attention to social trends - such as Niu Yun's Abariri, such as 4G, such as rice mobile phones......

"Listen to me, let's imagine a bicycle. ”

Jiang Chao smiled, his eyes full of light.

"First of all, it can be parked anywhere in the school where you can park. For example, downstairs in our dormitory, now that I'm ready to go to class, I walk to the bike. ”

"At this time, the bike is locked, and there is a device on the bike that I have to pay a certain cost to open, such as swiping a card or flipping a coin. I paid the cost, the bike was opened, and I rode it to the school building and parked it. ”

"Then I had to lock my bike...... Well, well, there's something wrong here, is there any way to get a cyclist to lock the bike compulsorily?"

When Judy heard this, she became excited, and she patted her head lightly: "Ah! Replace the parking pile with a lock, Jiang Chao, you are so smart! Listen to me, I think you can achieve it in this way!"

"Huh?"

Judy said: "Actually, we just need to make the cost of unlocking a continuous cost, and only when the lock is closed, can the cost consumption end." For example, you can set up a car card, and when you plug it in, you can continue to deduct the fee on time, and only when you lock it can you end the deduction - well, but this method also has certain limitations, such as if the cost of the card is lower than the price of each bicycle, there is still a risk of losing the car......"

The more Judy thought about it, the more she felt that her ideas were still a little immature and there were too many loopholes, she couldn't help frowning.

Jiang Chao groaned, suddenly, his mind already had a complete idea, he raised his head slightly, looked at Judy, and then looked at Dong Slow, and laughed: "Judy, Dong Slow, do you want to do something big?"

"Huh?"

Dong Slow and Judy said in unison, both stunned.

Jiang Chao laughed easily: "I'll tell you the full idea tomorrow." ”

The rain came and went quickly, and the thick dark clouds had dimmed the light a lot just now, but now the rain had stopped, and a beam of sunlight had pierced down.

……

The next day, Jiang Chao took Judy and Dong Slow to find an empty classroom at random and get in, and then opened the things he got out of yesterday's busy night.

A piece of sketch paper is a blueprint of a bicycle drawn with an ink pen. There are also many text descriptions on the side of the drawing. But after all, it is a hand-drawn drawing, and it looks rough. But Judy's attention was on the beautiful handwriting on the drawing, and the more she looked at it, the more fascinated she became, and then she glanced up at Jiang Chao slightly.

"I've been thinking about it for a long time, you see...... I also took into account the ongoing costs that Judy said yesterday, we can design an app that unlocks the ...... by paying or operating on the app."

Jiang Chao pointed to the design sketch of the bicycle and described in detail about this "new concept" of shared bicycles. Jiang Chao said, "We have to thank the rapid development of the mobile Internet and mobile terminals and even the Internet of Things, so that this thing can have the conditions and foundation for realization." ”

Jiang Chao talked about the profit model, operation model and technical support needed for shared bicycles. The first two aspects Judy and Dong Chu both understood, but the third level, the technical level of things, Judy heard in a fog, but it did not prevent her from listening excitedly, silently watching Jiang Chao, trying not to let the emotions flow out, in fact, he had been thinking in his heart for a long time, he was really focused on doing things!

Judy and Dong Slow are both expressing their opinions on the areas they understand, Judy is talking about some models, management and other words, her views and ideas from time to time make Jiang Chao's eyes shine, and the new concept of shared bicycles is more perfect. Dong Slow, who is not only proficient in program algorithms, but also has a dabbling in the underlying mechanical language, has professionally evaluated the feasibility of each unit of the intelligent lock, the core component of Jiang Chao's bicycle.

Jiang Chao was very excited, sure enough, a person's strength is limited, and many ideas from Judy and Dong Slow gave him a bright feeling, and the concept of shared bicycles is becoming more and more perfect. The more they talked, the more energetic they became, and later on, they were not simply discussing the bike-sharing itself.

Dong slowly got up excitedly: "Down-to-earth, bigger and stronger!

"Click!"

The door suddenly opened. A girl who was looking for an empty classroom to study suddenly opened the door, and just heard Dong Slow's words. In particular, the words "hundreds of millions, bigger and stronger" are particularly conspicuous.

Dong Slow's expression froze, and he looked at the girl blankly.

The air was a little cool, the atmosphere was a little delicate, and the girl who was at a loss bowed awkwardly: "Sorry, I'm sorry to disturb!" After speaking, she quickly closed the door and exited.

Dong slowly coughed lightly, "It's really a disappointment." Do it all over again, and get him hundreds of millions of ...... when the time comes."

"Click!"

The door was opened again.

Dong turned around angrily, "What are you doing?"

The aunt in charge of locking the door looked confused: "Same ...... Classmate, it's time to lock the door. ”

Dong Slow's face turned red, and he said ashamedly: "I know...... Got it. ”

Jiang Chao and Judy laughed.

……

The three of them had dinner, Jiang Chao invited guests, and the three of them walked together in the school. Although they were addicted to it during the day, after calming down, Judy and Dong Chu didn't really take the shared bicycle that Jiang Chao said seriously, maybe it was funny, but neither of them thought that the three of them could get the shared bicycle out.

Jiang Chao suddenly smiled and asked, "Judy, is our project feasible?"

Judy was stunned, Dong Slow was also stunned, listening to Jiang Chao's meaning, is he planning to play really?
