2014, Huaguo, Jinling City.

The June sun scorched the earth, as if it were about to steam out the last trace of moisture on the asphalt road.

Looking at the pedestrians hurrying back and forth on the street, listening to the noisy car whistle in his ears, Lu Zhou, who was standing in front of the Unicom business hall, stared straight at the street with his eyes. Although the cold air wafted from time to time behind him, the one-finger-thick puppet costume made him not feel the gift from the air conditioner at all.

Why is he standing here?

Because of life, of course......

Well, to speak human words.

During the summer vacation, the Unicom business hall cooperated with vivo mobile phone manufacturers to carry out promotions, as long as they stood at the door in a puppet costume, it was 60 yuan an hour, which was almost twice as much as sending leaflets, and they didn't have to be looked down upon. In addition, the outdoor temperature exceeds 30 degrees, and there is a high temperature subsidy of 10 yuan per hour, which is 70 yuan per hour.

As soon as he heard this salary, Lu Zhou didn't think much about it, and immediately accepted it without hesitation.

Rational analysis, the average working time is 5 hours a day, and it is 350 yuan a day. If you work 30 days a month, it is 10,500 yuan.

Who would have thought that the position with an annual salary of 100,000 yuan turned out to be at the door of Unicom's business hall?

Of course, Lu Zhou also knows, let alone vivo, even if it is a wealthy Warwick, it is impossible to engage in promotions every day.

But even if you only work for a week, that's about 2,600 yuan.

Just when Lu Zhou was so bored that he began to count a few leaves on the plane tree at the door, a fat man with a slightly dark complexion walked over to Lu Zhou while wiping the sweat on his face.

This fat man's name is Wu Dahai, and he is studying in the mathematics department of Jinling University like Lu Zhou, but he is two years older than Lu Zhou, and he is in his junior year, and he will be a senior in a few months. As the leader of these part-time students, this job of wearing a puppet costume was introduced to Lu Zhou.

"Lu Zhou, can you do it? Why don't we find someone to change off work, you go to the business hall to rest for a while. Because he is afraid of heat, Wu Dahai's whole body is like being fished out of the water, and he is wet all over his body.

Although he wanted to rest, Lu Zhou still shook his head: "I'm fine, I can hold on a little longer." ”

"I said, are you really okay or are you fake? You've been standing here for almost an afternoon. Wu Dahai said with a bitter face.

He was really afraid that this guy was suffering from heat stroke.

"I'm really fine, you don't have to worry about me," Lu Zhou shook his head firmly, "There is still an hour to get off work, anyway, it's been standing for so long, it's not bad for this hour, don't you say?" ”

Wu Dahai glanced at Lu Zhou hesitantly and said, "That...... I really don't care about you. ”

"Well, you go about your business."

Seeing that Lu Zhou was so resolute, Wu Dahai no longer insisted.

In fact, there is no trace of luck in his heart.

After all, in such a hot weather, it is not easy to arrange someone to work at the top of the class. Although there are many people who work part-time in his hands, there are few people like Lu Zhou, and he has to wear this "big padded jacket" by himself in the end.

Looking at the fat man's distant back, Lu Zhou withdrew his gaze from him and continued to stare at the sycamore at the door of the business hall in a daze.

At this moment, he suddenly felt that something was wrong with the scene in front of him.

Pedestrians on this street...... How are you flying into the sky?

As soon as his legs and stomach became weak, the whole person fell backwards.

With the remnants of his consciousness, he vaguely heard hurried footsteps and shouts coming from the business hall behind him.

"The mascot at the door has a heat stroke!"

"Quick, take off his hood and get a glass of water!"

"Hold the grass, Lu Zhou, you kid can't be fine!"

"No, no response, send it to the hospital quickly!"

"Get in my car."

“……”

The last rays of light cut off from view, and with it, boundless darkness......

……

Lu Zhou, an undergraduate student in the Department of Mathematics at Jinling University, is currently a freshman and will be a sophomore in a few months. When he first filled in the volunteer, he originally applied for software engineering, but because of the difference in scores, he was transferred to the unpopular mathematics department.

Sometimes Lu Zhou can't help but ask himself, this egg. What is the use of studying in four years in a painful major?

Seems like an inexplicable answer.

There are only two conventional paths out of the mathematics department, either to continue your studies (to go abroad or to go to graduate school) or to change to other majors.

Actually, there's another way to stay in school, but it's not for undergraduates, unless you have a particularly strong relationship with your teacher. However, even so, it is a miscellaneous thing to stay, and it is better to go directly to the graduate school entrance examination.

However, for Lu Zhou, the postgraduate entrance examination is still a little unrealistic.

Lu Zhou's hometown is in Jiangling, although there is only one word difference from Jinling, but the geographical location is 108,000 miles away. His father works in the Gangneung Iron and Steel Plant and is an ordinary worker, as for his wife, he has long been laid off at home, and his physical condition has not been very good, so he has spent a lot of money to see a doctor.

The income of the whole family depends on his father alone, not to mention that he also has a younger sister who is in high school, and when the time comes, he will be admitted to college, which is a big expense.

Although Daddy meant that he didn't have to worry about money, it was best to keep studying and strive to come back from a PhD.

However, Lu Zhou knew very well that this was impossible.

He has already stepped into society with half a foot, and he has to think about more practical problems.

More specifically, it's about money.

He didn't want to be a burden to his family or drag down his sister, so he worked hard to be financially self-reliant since he went to college. When others are participating in club activities to praise their youth, or studying hard in the library, he is more likely to distribute flyers, install routers, and deliver takeaways.

Sometimes he can't help but ask himself, what's the point of such a college life? The work I am doing is unskilled, even if I have graduated from junior high school, I can do it, or even better than myself, at least I will not get heat stroke after standing outside the air-conditioned room for a few hours.

But this question is the same as the previous question, "The way out of the mathematics department", and there is no answer to it.

Now, he's down......

Consciousness returned, standing in the white expanse of the day, Lu Zhou's eyes looked around blankly.

"What the hell...... Where is it? ”

No one answered.

Vague memories told me that I seemed to faint from heat stroke at the door of Unicom's business hall. Later, it seems that he was carried into the car by well-wishers and sent to a nearby hospital, but there is a little hospital here, and it doesn't even look like the real world at all.

Just when Lu Zhou began to feel anxious about his situation, suddenly a translucent screen suddenly appeared in front of him, making his whole person jump back in fright.

"Black Technology...... System? What the heck?! ”

Looking at the black text that gradually emerged from the translucent screen, Lu Zhou was startled at first, and then fell into ecstasy.

Could it be ...... Chosen by the legendary system?

He still reads online novels.

Swallowing and foaming, Lu Zhou hurriedly asked, "System...... So, what are your features? ”

However, there was no mysterious voiceover to respond to his question, and the translucent holographic screen appeared on its own.

Black Technology System:

This system is committed to improving the level of aboriginal civilization, about the secrets of this system, please explore by yourself, and now for the functions of this system, to the system holder to explain in detail.

The main page of the system is described as follows.

※Trunk Science: (The backbone of the science tree, focusing on theoretical directions.) The level is capped at 10, and experience can only be earned through quests, not through points exchange. A full tech tree will unlock the Future Era option, as well as the Megastructure Quest)

A. Mathematics: The foundation of all disciplines determines the upper limit of the other main science grades.

B. Physics: It helps you understand the universe.

C. Biochemistry: It helps you to recognize yourself.

D. Engineering: Transform tools, transform the environment, transform the world.

E. Materials Science: Materials and engineering are inseparable

F: Energy science: from fossil fuels to helium-three, from solid-state lithium-air batteries to antimatter batteries, from wireless power transmission to ultra-long-distance laser conduction, life feeds on negative entropy, the end of energy development, in the distant sea of stars......

F. Informatics: Genetics is God's code, and the ultimate goal of the code is to create God.

----------

※Branch technology: It is a branch of science and technology. After unlocking a specific branch of technology, the experience required to level up can be exchanged for 1 point.

For example, if genetics LV1 requires biochemistry LV1, you can light up genetics LV1 (0/1000) by consuming 100 points.

Genetics LV2 meets the requirements of biochemistry LV2, engineering LV1, and experience value of 1000 at the same time, and can upgrade genetics LV1 to genetics LV2 (0/?). ）。

----------

Technical drawings: As the name suggests, technical drawings that are easy to understand. As small as a nanochip, as large as a giant engineering Dyson sphere. Under the objective conditions required for production, production can be realized in accordance with the steps of the drawings.

----------

Points: Can be used to start a reward task, or to spend 200 points to re-randomize the task, which can be used to spend points to solve technical problems (the consumption of points is determined by the subject level, the tendency of the technical problem, and the difficulty of solving the problem. ）

Missions: Three random tasks appear each time, you can choose one of them as the target to execute, and complete the task to get the corresponding reward. Once the task is completed, the task panel will be reset.

】

At this moment, Lu Zhou doesn't know what to do and what he thinks, and the mathematics he thinks is chicken seems to be the opposite in this system, becoming the father of all other disciplines? The taste of this salted fish turning over really made him a little speechless.

What makes him even more powerless to complain is still to come.

As soon as the caption vanished, his properties panel reappeared.

Anyway, master, I'm also a 985, although I can't be considered a school bully after I come in, but this string of zero eggs...... Do you look down on me too much?

Looking at this string of dazzling eggs, Lu Zhou thought with tears and laughter.

Something must have gone wrong with this system!

Just as Lu Zhou was thinking this, there was a sudden violent shaking on his shoulder, and then his consciousness was pulled out of this pure white space......
