I Have A Super USB Drive

Chapter 9: 009-Go to the library

"Insufficient energy."

Looking at the latest pop-up window, Chen Chen looked thoughtful.

Obviously, the most difficult situation has arisen.

Because the USB flash drive embodies NZT-48, it has exhausted its energy and cannot embody other things again.

However, Chen Chen also got good news.

Since the words "insufficient energy" can appear, it can be reversely explained that the USB flash drive can be charged.

As long as things haven't reached the worst point, there is still a chance to recover.

But, what kind of energy does he need for this USB flash drive

Chen Chen stared at the old and dim USB flash drive in front of him, and suddenly his heart moved.

He walked to the door of the dormitory and looked up.

An IC card meter is embedded in the wall.

Because it is located along the coast, air conditioners are often needed, so the dormitories of Shangdu Jiaotong University do not restrict high-power electrical appliances.

However, each dormitory has an electric switch, and the total power is limited to about 10A.

At this time, the electricity meter showed that the electricity card in dormitory 404 still had 52.65 kilowatt-hours of available electricity.

Power

Chen Chen turned around and found the manual for his laptop. He found that the output voltage of his computer was 19V and the output current was 7.8A.

In other words, the rated power of the notebook is about 150W, which consumes 0.15 kilowatt-hours of electricity per hour.

In the USB protocol specification, the USB power supply voltage is about 5V, and the maximum power supply current is 500mA. In other words, the maximum output power of a single USB port is 2.5W, and the energy consumption is about 0.0025 degrees per hour.

Thinking of this, Chen Chen frowned, pulled out the USB flash drive, and looked at the wiring board on the table.

This power strip was purchased by four people in the dormitory through crowdfunding at the beginning of the semester. It is placed on the table and is fully sufficient for the daily use of four people.

And for convenience, I bought a wiring board with a dedicated USB jack.

Chen Chen looked at the wiring board. The power of the USB jack marked on it is 5V, 4A. In other words, the maximum power of the USB interface is 20W, and the power consumption is 0.02 degrees per hour.

Thinking of this, Chen Chen inserted the USB flash drive into the USB jack of the wiring board.

"If my guess is correct, the USB flash drive can use electricity to replenish energy, then it should be reflected on the electricity meter."

Chen Chen thought about it. Now the only power-consuming device in the dormitory is the computer. As long as the computer is turned off, if the electricity meter is still running after an hour, it means that the USB flash drive can really absorb electricity.

The reason why it was not directly plugged into the computer's USB interface before was because the computer's USB power was too small, and the electricity meter could only reflect the last two decimal places at most. If it was plugged into the computer's USB, even if there was energy consumption, it would not be visible at all.

After checking the time, Chen Chen took out his phone and set an alarm for one hour.

Then, he turned off the computer, opened a copy of "Modern Molecular Biology" and started reading silently.

The hour flew by.

When the alarm clock on his phone rang, Chen Chen happened to have turned the last page, but at this time Chen Chen was not satisfied.

The book "Modern Molecular Biology" is not bad for teaching, but for Chen Chen, it is a bit crude and general and cannot satisfy the depth of his study.

It seems that after finishing this work, it is necessary to go to the library.

Chen Chen made up his mind, then walked to the meter again and looked at the numbers on it.

Available power: 52.63 kWh.

It consumes 0.02 kilowatt hours in one hour, and sure enough!

Chen Chen's eyes lit up. At this moment, he was sure that the USB flash drive could really charge himself with electricity.

This discovery is exciting and is no less significant than the discovery of NZT-48.

Just when Chen Chen was excited, his ears suddenly twitched slightly, and then he quickly pulled out the USB flash drive and stuffed it into his pocket.

There was a sound of footsteps approaching from far away. Chen Chen looked towards the door, and suddenly the dormitory door was kicked open with a "clang".

Li Bo walked in with steps that would shake society.

"Chen Chen, you didn't go to class in the afternoon!"

Seeing Chen Chen staying in the dormitory, Li Bo immediately shouted, "Old Deng called your name and asked you specifically!"

"I asked the counselor for leave."

Chen Chen said without looking back, "Bo Zai, let's not get together in the future."

"Why?"

"Walking with you, I'm afraid of getting beaten when I go out."

Chen Chen packed up his books and saw that it was not yet five o'clock in the afternoon, so he got up and walked out of the dormitory.

"Where are you going? Let's have a dinner with AA outside later?"

"No money, farewell."

Chen Chen left without looking back.

His state at this time was obviously different from before, and even Chen Chen himself could detect this.

If he was just a low-key and dull young man before, then now he is a successful man full of confidence and calmness.

No fear, no shyness, no shyness...

Some, just calm and unhurried confidence.

This kind of aura was difficult to conceal, so Chen Chen stayed away from acquaintances as much as possible to avoid any flaws being seen.

When he came to the canteen, Chen Chen bought four steamed buns for two yuan, ate two, and then put the remaining two in a plastic bag for later use when he got hungry at night.

The life of a poor person is so simple and unpretentious.

And boring.

Chen Chen walked towards the library while thinking about the next steps.

If you want to reach the top of your life, although relying on NZT-48 is enough, how can you be satisfied with this if you don't have enough people

My next step, of course, is to find ways to charge the USB flash drive and try to squeeze out the maximum value from the USB flash drive.

You know, the power of the USB interface of the cable board is definitely not enough.

Although I don’t know how much energy a USB flash drive requires to meet the conditions for realization, you can guess it with your toes. It is definitely an astronomical figure.

Therefore, Chen Chen needs a lot of money.

Once you have money, you can handle it with ease, whether it is buying a factory in an industrial park or building a power plant yourself.

Only in this way can Chen Chen supply enough power to the USB flash drive without being noticed by the outside world.

So, the source of all this is money.

Now, there is only one way for Chen Chen to obtain money, and that is to rely on the power of NZT.

Thinking of this, Chen Chen no longer hesitated and stepped into the library building with both feet.

Looking at the crowds coming and going in the library, Chen Chen sighed silently.

In the next period of time, I will stay here permanently.

The library is never short of situations where "books are there but people are not". There are stacks of books occupying several convenient and quiet prime locations. If someone hadn't cleaned them at night, I'm afraid some books would have piled up dust.

Chen Chen came to the foreign language reading room, glanced at it a few times, picked out a book called "Modern College English (Second Edition)", found a decent seat and sat down.

Chen Chen once wondered when he was in junior high school and high school, why did Zhongzhou regard North American languages as a compulsory course, and why did it occupy such a large proportion

Until just now, Chen Chen suddenly understood.

Although I don’t want to admit it, the North American region is the real core region of the federation, whether it is economy or technology, it is the real core.

Most of the truly profound and authoritative academic papers are written in English.

Some academic and professional words are difficult to explain in Chinese, and even if they are translated, the meaning is still missing.

And just such a meaning is often missed by a thousand miles, creating many difficulties for Zhongzhou's scientific research.

Therefore, if Chen Chen wants to enter the field of scientific research, proficiency in English is the most basic stepping stone.

This is the good intentions of the older generation in Zhongzhou’s education community.

Not to worship foreigners, not to turn your elbows outward, just to keep up with their pace.

That's all.
