Li Yang has two mobile phones now.

One is brought from the previous life, and the other is bought from home.

I have to say that my parents are really good to Li Yang. The family was originally in trouble, but now it is an era when there are telephone booths on the street. You need a phone card to bring a phone. Stores set up phone bars, and landlines charge a minute.

There are still a few people who insist on using pagers, which are commonly referred to as bb machines. However, in just a few years, bb machines will completely disappear and become history.

But the family members were worried about Li Yang, so they gritted their teeth and bought Li Yang a mobile phone. It was the simplest and cheapest type. Apart from calling and sending text messages, they could only finish playing with the greedy snake.

Li Yang's parents didn't come with him, but just wanted to save some money and let Li Yang take it with him.

The older generation said that the poor family is rich. This sentence is even more lingering on Li Yang's father's mouth. Even if Li Yang wants to refuse, he still forcibly gets a lot of money.

Thinking of this, Li Yang became even more determined to make a lot of money. However, everything was difficult at the beginning, and this first pot of gold made Li Yang a little worried.

According to Li Yang's advantages, whether it is writing novels, movies, or songs, as long as it is copying the article, you will definitely be able to live a good life.

But the problem is that it is too early. When writing songs, the copyright awareness has not yet been formed, and writing them may not be cheap. If you want to make movies, let’s not talk about anything else. Nowadays, film factories are the biggest. Whether it is a TV series or a movie, it will take at least three or four years to reach the turning point. As for novels, there are still two years left before the starting point of the largest novel website.

Too early.

Although even pigs can fly into the sky when standing at the wind, it is obvious that the current wind direction has not yet blown into the entertainment industry, so Li Yang has few opportunities.

Although he was calm, it was too slow and Li Yang didn't like this feeling of being unsure.

While Li Yang was sitting in the dormitory bed in a daze, he heard his roommate Zhang Yao holding his cell phone battery and asked, "Well, who do you lend me a charger? My battery is about to run out of power, and I don't bring the charger."

Li Yang said casually: "Isn't that the one on the table? There are mine and some of them. Just take one of them."

"No!" Zhang Yao said: "My mobile phone model is different from yours. I forgot to bring a supporting charging device. I still have to buy a new one for more than 100, so I really can't stand it."

Li Yang asked: "What charger costs more than 100? Wouldn't you just need to get a universal charge?"

Zhang Yao looked at Li Yang and was confused: "What is universal charging? Forget it, I'd better go to another dormitory to borrow it. It's really hard to charge your phone, so they can't unify the charging interface?"

Zhang Yao left complainingly, and the rest of them were used to it.

But Li Yang couldn't sit still because he found that he seemed to be spending time sighing at his past friends, but missed an important news!

This year, Apple phones have not yet been released.

This year, the unification of Android interfaces has not been achieved.

This year, every brand of mobile phone on the market has its own unique charging interface and is incompatible with each other.

This year, there are still two years left before universal charging was invented.

Before universal charging was invented, mobile phone accessories were the money tree of mobile phone manufacturers. Because of their incompatible characteristics, mobile phone chargers became expensive. Chargers that were originally cost ten yuan could be bought by mobile phone manufacturers for hundreds of yuan.

This is the huge profits brought by technological monopoly.

Until 2002, a brain-loving high school student in Henan also encountered such troubles in life. He was like inventing a charging device that could be compatible with all mobile phones, but his idea was directly denied by adults.

But the high school student did not give up. Later, he went to the mobile phone store to pretend to buy a mobile phone, study mobile phone accessories, and bought a lot of chargers and took them apart and thought about the structure and principles.

After studying 263 types of mobile phone batteries, the high school student found that the only difference between mobile phone batteries is the distance between the two charging electric shocks of the mobile phone batteries, that's all!

Later on, things became simple. Two weeks later, the high school student invented the world's first universal charging. He could adjust the distance of the charging interface at will and charge any mobile phone battery.

Subsequently, the high school student applied for a patent number. Because of this invention, the high school student won the first prize in the National Youth Science and Technology Innovation Competition and was directly admitted to Tsinghua University.

Universal charging not only changed the fate of this high school student, but also directly changed the game rules of the entire mobile phone market.

After the universal charging was put into mass production, the first batch was sold out in three days after hundreds of thousands of yuan. Then there was a shortage of supply and demand. The hundreds of millions of mobile phone users and huge market demand brought by the economic income was also very terrifying.

The birth of universal charging directly caused the mobile phone manufacturers to suffer the bitter fruit. The previous ten yuan charger manufacturer dared to buy hundreds of dollars, but did not buy them if they liked it.

After the universal charging appeared, all mobile phone manufacturers sold mobile phones and directly gave chargers for free. Not to mention a hundred yuan, they didn’t want a penny, and they were forced to you as they cried and shouted!

Universal charging can unify the world and make mobile phone manufacturers make money in accessories almost cut off! But they have no choice.

However, universal charging eventually gradually disappeared into people's lives. It was not because of universal charging itself, but because mobile phones ushered in a new era!

A few years later, Apple phones were released, and the first time it innovated the precedent of mobile phone batteries that cannot be detached was imitated by major mobile phone manufacturers. Major manufacturers later designated unified charging interface standards.

Until the era of touch came in full swing, there were almost no mobile phones on the market that could disassemble batteries. Without removable batteries, universal charging was completely reduced to waste.

Universal charging was eliminated not because universal charging was not good. It was just because society was developing and the times were progressing. If universal charging was like a small revolution, it changed the pattern of the mobile phone accessories market. Then the later era of technology was like a vast era, which directly allowed the world's technological products to enter a new field.

The fact that Apple’s Joe Gang is praised is not only because of the mobile phone, but also because of the huge significance behind the mobile phone. It was a new era!

And now...

Standing at the fork in history, Li Yang looked at the charging cable on the desk and smiled.

I am still too biased and a little self-righteous. It turns out that what can change everything is sometimes the smallest aspect.

Then, if the appearance of universal recharge is an inevitable product, the inventor will change another person, I'm sorry.

Li Yang hid in the quilt, secretly took out his original mobile phone, and soon found the structural design drawing of Universal Charging from the Internet.

It is really a very simple design. Even people like Li Yang who don’t understand can read it. Because universal charging itself does not have any technical content. What is really important is the belief that dares to break through inherent concepts and dares to study hard when everyone denies you.

There is no so-called good luck in the world. After all, not everyone uses patience to study 263 different mobile phone batteries.

But at this time, Li Yang couldn't help laughing.

This is information asymmetry, which comes from the crushing future.

Sure enough, rebirth is already his greatest luck.
