Back in the room after dinner, Chen Yuan lay on the bed with empty eyes.

If you think Chen Yuan is in a daze, you are wrong.

Chen Yuan kept calling in his heart: "System, system, system, your uncle, come out quickly!"

That's right, Chen Yuan has a system!

Chen Yuan didn't just discover that he had a system, he found out after crossing over two years ago.

It's just that the system keeps saying that the energy is insufficient and cannot be activated. Chen Yuan tried all kinds of ways but couldn't recharge it, eating and drinking, electrocution, fire, flooding, etc., and he almost dripped blood.

But the system is formless and substantial, and you can't find a target if you want to drop blood!

"Didi... The system is low on energy, please recharge it in time!"

An interface with red characters on a black background flashed in front of Chen Yuan's eyes.

"Damn, you have the energy to show that the energy is insufficient, can't you use this energy to tell me how to recharge?" Chen Yuan said angrily.

Every time the summoning system is displayed like this, Chen Yuan wants to go crazy!

The system ignored Chen Yuan very arrogantly, and turned off the screen by itself.

After Chen Yuan's limbs waved a few times, he stopped abruptly.

Since coming to this world, Chen Yuan has to repeat this process almost every day.

Chen Yuan, who was originally an ordinary office worker, accidentally penetrated into this world that is connected to the Classic of Mountains and Seas two years ago, that's right, this is a world that has been connected to the world of the Classic of Mountains and Seas in two hundred years!

Everything recorded in the Classic of Mountains and Seas is here, and there are many more that are not recorded.

It's just that unlike the records of the Book of Mountains and Seas, all non-humans in this world are enemies of human beings, and when they are caught, they are either devoured or used as slaves.

In order not to become food and slaves for foreign beasts, human beings tried their best to keep the Eurasian continent of the original earth for human reproduction. It's not that human beings don't want to keep more territory, but since the connection with the mountains and seas through the world, maybe the earth's magnetic field, maybe the particles that make up everything have changed, resulting in human technology being unusable, and those weapons of mass destruction have been directly reduced to a pile of scrap copper and rotten iron.

But human wisdom is infinite, after firmly occupying the Eurasian continent, human beings built a siege, through the efforts of scientists, the technology in the besieged city can be used unimpeded, which also allows human beings to get a respite.

subsequently

Chen Yuan also learned that the world after the breakthrough was hundreds of times larger than the world he was familiar with, so the place occupied by human beings was very small, very small!

When human beings settled down, they began to embark on the parallel road of martial arts civilization and technological civilization.

Technological civilization can be used in the siege of human beings, and guards the safety and order of human beings in the siege, and the martial arts civilization protects human beings outside, and does not provide various resources for the development of scientific and technological civilization.

The importance of martial arts civilization here is higher than that of scientific and technological civilization, because the development of scientific and technological civilization is inseparable from the support of martial arts civilization, and after two hundred years of development, the deterrent power of martial arts powerhouses has gradually surpassed that of science and technology, but martial arts powerhouses still need to rely on technology to manage besieged cities!

At present, mankind has built nearly 1,000 sieges on the Eurasian continent, with a total population of more than 10 billion.

Although the population is large, the new world has more resources, and there is no problem in meeting the food and clothing of tens of billions of people!

However, human beings did not rest on their laurels, but took the initiative to expand outward and strive for more living space.

This is a high-risk world, Chen Yuan is like a mirror in his heart.

The devastated city that was destroyed by strange beasts a month ago reminded Chen Yuan that this world was very dangerous, he had no strength, and he could lose his life at any time.

So Chen Yuan is eager to become stronger, he doesn't want to take the road of science and technology, he wants to take the road of martial arts!

Therefore, after crossing over, Chen Yuan spent a year being admitted to Jiangnan Martial Arts University, a school where human beings train martial arts powerhouses, and only Chen Yuan himself knows the efforts he has made.

Jiangnan City has a total population of 30 million, but there is only one Wuhan University, and every student admitted to Jiangnan Wuhan University is a genius in ten thousand.

So when it was possible that he couldn't pay the fees for Wu University, Chen Yuan would be so unwilling. And once the opportunity arises, Chen Yuan will be so desperate.

Of course, Chen Yuan is not stupid, knowing that cleaning up is a high-risk profession and still going to die.

It's just that Chen Yuan has a guess in his heart, and this guess may be answered when he is a cleaner!

Three days later in the morning.

Chen Yuan came to the gate of Xicheng early, simply had breakfast here, and sat in the breakfast shop watching the people coming and going.

Everyone here gave Chen Yuan a great feeling, and Chen Yuan almost vomited the breakfast he had just eaten.

Because since the city gate was opened at eight o'clock, there have been many embarrassed people, and many people who have only been bandaged with broken hands and feet, and of course there are corpses that have been carried back!

I don't know, I thought I was back in a city in ancient times that was at war.

"How is it, isn't this scene particularly exciting?" Zhen Le didn't know when he came to Chen Yuan's side.

Chen Yuan couldn't understand Zhen Le's words!

Zhen Le continued: "Yes, I didn't mistake you, daring to come as a cleaner shows that you also have a stronger heart like me!"

Chen Yuan: "I just want to earn tuition!"

Zhen Le: "It doesn't matter, you just need to know that people who have worked as cleaners can be on the list." ”

Chen Yuan: "......"

Zhen Le said again: "Don't say that I don't take care of my classmates, I will be divided into groups after I become a cleaner, I will assign you to my group, and I will be your team leader, rest assured, I will take care of you, I will not only let you earn enough for your tuition in these two months, but also let your martial arts cultivation grow greatly!"

Chen Yuan was puzzled: "You are the team leader, don't the team leaders require soldier-level strength?"

Zhen Le smiled and said, "I broke through last night, and the one standing in front of you is a proper soldier-level powerhouse!"

"You can be the team leader just after breaking through, you didn't lie to me?" Chen Yuan said.

Zhen Le: "I read a lot of books, I won't lie to you!"

Chen Yuan: "Then I won't be in a group with you, you rookie, don't bother me if you want to die!"

During the three days at home, Chen Yuan was not idle, and still checked the information.

Judging from the news published on the Internet, when the general clean-up workers go out of the city to clean up the battlefield, there will be a general-level warrior to lead the team, and then divide into several groups, the leader of each group requires that the strength must reach the level of the soldier, and the junior level of the soldier level shall not lead the team as the team leader in principle, but can only act as the deputy team leader.

A rookie like Zhen Le, who has just become a junior soldier, doesn't even have the qualifications to be a deputy team leader.

Of course, there are no absolutes in everything, as long as the family is rich and powerful, any illegal operation can be operated.

Zhen Le said: "Hey, although I am the deputy team leader this time, my Lao Tzu has already helped me find a team leader with half a year of experience to lead the team!"

Chen Yuan was surprised: "Are you sure it's half a year?"

Zhen Le said: "Absolutely, my son will not fool me in this kind of thing!"

", God!" Chen Yuan exclaimed.

He is indeed a man of God, who can work for half a year in this work that is generally less than a month, and he is definitely a man of God!

There is no outstanding point, and it is basically impossible to hold out for half a year with only the strength of the military level.

Zhen Le: "Let's go, brother will fly with you!"

After speaking, Zhen Le walked towards a building not far away.

"Wait... Wait for me!"

Just as the two were about to enter the gate, Gundam arrived panting.

Chen Yuan and Zhen Le were a little surprised, and they didn't know how Gundam came over.

Chen Yuan: "Why are you here, don't you have to go to work?"

Chen Yuan has also contacted Gundam in the past three days, knowing that he has already gone to do his summer job, and it stands to reason that this time is already work time, and I don't know why he is here.

Gao said: "Don't say it, that job is not done by people at all, I repeat one thing every day, I am not a machine, I am annoyed to death!"

Zhen Le snorted and said: "Hmph, not most people who graduated from Wuhan University are engaged in this kind of work, it's not that we look down on this kind of work, since we have been admitted to Wuhan University, it means that we have to bear more responsibilities than others, and it is our mission to work hard to protect the Acropolis after graduating from Wuhan University!"

Gouda: "Hey, when did you become so enlightened as a rich boy?"

Zhen Le raised his head arrogantly.

Chen Yuan said: "Gundam, you don't need to come here even if that job is boring, right?"

Gundam: "Zhen Le, this bastard, dares to do this job, which means that his family must have thought about his safety, and his safety is guaranteed, and such a high-paying job, even if it is dangerous, it is hundreds of times better than the boring work that is repeated day after day!"

Chen Yuan was dumbfounded, Chen Yuan had already thought of this point of safety and security with Zhen Le, and it was just to deceive Zhen Le's arrangement before.

Anyway, the Zhen family has already arranged it, and it will definitely not suffer a loss if you follow Zhen Le.

The three of them casually laughed and entered the premises dedicated to managing the cleaners, and after Zhen Le took Chen Yuan and Gundam to register, they waited in a corner of the hall under the guidance of the staff.

There were still nearly a hundred people in the hall waiting for the arrangement like the three of them, and unlike the relaxed expressions on the faces of Chen Yuan and the three of them, most of these people had blank faces.

In the crowd, Chen Yuan found that there were seven or eight people who were about the same age as the three of them.

"They're from Anding Academy!" Zhen Le said.

"Anding Academy?" asked Chen Yuan.

Anding College is an ordinary university in Jiangnan City, but it is also considered the top among ordinary universities, and the university has a martial arts class to accept students who have not been admitted to Wuhan University and have good qualifications.

However, because there is no funding from Wuhan University, both resources and strength are far inferior to Wuhan University, so they need to rely on themselves to fight for everything.

So you can see them here.

And the students of Jiangnan Wuhan University have no need to engage in such a dangerous job, even if many people know that the strong people on the Tianbang have the experience of working as cleaners, the school and parents will not let students do this job, because it is too dangerous.

"Well, I hope I won't be in the same group with them later. Zhen Le said
