"Not enough energy."

Looking at the latest pop-up window, Chen Chen showed a contemplative look.

Clearly, the most difficult situation has emerged.

The USB flash drive has run out of energy because of the NZT-48 emulation, and it is impossible to remanifest anything else.

However, Chen Chen also got good news.

Since the word "insufficient energy" can appear, it can be reversed to show that the USB flash drive can be charged.

As long as things don't get to the worst, there is still a chance to redeem them.

It's just, what kind of energy does he need for this USB flash drive?

Chen Chen stared straight 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 on the coast, it is often necessary to use air conditioners, so the dormitory of Shangdu Jiaotong University does not restrict high-power electrical appliances.

However, each dormitory has a power switch, and the total power is limited to around 10A.

At this time, the meter showed that there was still 52.65 kWh of available electricity in the electricity card of dormitory 404.

Battery?

Chen Chen turned around, found out the manual of the laptop, and 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, and it consumes 0.15 kWh of electricity in one hour.

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

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

This power strip was bought by four people in the dormitory at the beginning of the school year, and it was placed on the table, which was completely enough for the life of four people.

And for convenience, at that time, I bought a power strip with a USB jack.

Chen Chen looked at the wiring board, the USB jack power marked on it is 5V, 4A, that is to say, the maximum power of the USB interface is 20W, and the power consumption is 0.02 kWh per hour.

Thinking of this, Chen Chen plugged the USB flash drive into the USB jack of the power strip.

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

Chen Chen thought about it, now there is only one power-consuming device in the dormitory, as long as the computer is turned off, if the meter is still going after an hour, it means that the USB flash drive can really absorb electric energy.

The reason why I didn't plug in the USB port of the computer directly before was because the USB power of the computer was too small, and the meter could only reflect the last two decimal places at most.

Looking at the time, Chen Chen took out his mobile phone and set an alarm clock for another hour.

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

……

An hour flew by.

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

The book "Modern Molecular Biology" is not bad for teaching, but it is a bit rough and general for Chen Chen, and it cannot meet his depth of learning.

It seems that it is necessary to go to the library after this is done.

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

Available electricity: 52.63 kWh.

It consumed 0.02 kWh in one hour, and sure enough!

Chen Chen's eyes lit up, and at this time, he was sure that the USB flash drive could really recharge himself with electricity.

This discovery is inspiring, and no less significant than the manifestation of NZT-48.

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

There was a sound of footsteps from far and near, Chen Chen looked at the door, and suddenly the dormitory door was kicked open with a "bang".

Li Bo walked in with a socially shaken pace.

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

Seeing Chen Chen staying in the dormitory, Li Bo immediately shouted, "Lao Deng asked you by name!" ”

"I've taken a leave of absence from the counselor."

Chen Chen didn't reply, "Bo Zai, let's not walk together in the future." ”

"Why?"

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

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

"Where are you going, let's go out for dinner together?"

"No money, take your leave."

Chen Chen left without looking back.

At this time, his state was obviously different from what he used to be, which even Chen Chen himself could perceive.

If he was once just a low-key and wooden young man, now he is a successful person full of confidence and calmness.

No fear, no shyness, no shyness......

Yes, it's just a calm self-confidence.

This kind of aura is difficult to hide, so Chen Chen stayed away from acquaintances as much as possible, so as not to be seen as flawed.

When he came to the cafeteria, Chen Chen bought four buns for two yuan, ate two, and then put the remaining two in a plastic bag to keep them in a panic when he was hungry at night.

The life of a rich person is so unpretentious.

And boring.

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

If you want to reach the pinnacle of life, although it is enough to rely on NZT-48, but the heart is not enough to swallow the elephant, how can you be satisfied with this?

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

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

Although I don't know how much energy the USB flash drive needs to meet the embodiment conditions, I can think of it with my toes, which is definitely an astronomical amount.

Therefore, Chen Chen needs a lot of money.

After having money, whether you go to the industrial park to buy a factory or build a power plant yourself, you can calmly deal with it.

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.

And now, Chen Chen has only one way to get money, and that is to rely on the power of NZT.

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

Looking at the crowd coming and going in the reading hall, Chen Chen sighed silently.

For the next period of time, I'm going to be here for a long time.

There is never a shortage of 'books in the library', and several convenient and quiet prime locations are occupied by stacks of books, and if someone doesn't clean them up at night, I'm afraid some books can pile up dust.

Chen Chen came to the foreign language reading room, glanced at it a few times, picked out a copy of Modern College English (Second Edition), and found a decent place to sit down.

Chen Chen once wondered when he was in junior high school and high school, why did the North American language be regarded as a compulsory subject in the Middle Kingdom, and it still occupied such a large proportion?

Until just now, Chen Chen suddenly understood.

Although I don't want to admit it, North America is the real core area of the Union, both economically and technologically.

And most of the truly authoritative academic papers are written in English.

Some academic terms are difficult to explain in Chinese, and even if they are translated, they have a poor meaning.

And it is such a layer of meaning, which is often missed by a thousand miles, creating many difficulties for scientific research in Zhongzhou.

Therefore, if Chen Chen wants to step into the field of scientific research, then being proficient in English is the most basic stepping stone.

This is the good intentions of the older generation in the education sector of Zhongzhou.

It's not to flatter foreigners, it's not to turn elbows outward, just to keep up with them.

That's all.
