The Science Fiction World of Xueba

Before, Pang Xuelin had talked with the parents of this plane on the phone, hoping that they could return to Jiangcheng to work.

But later it was found that this was not realistic at all.

In this era, except for minors, the elderly, the sick, and disabled people who cannot take care of themselves, everyone must work.

Everyone will establish a credit account from birth, with credit points on it.

Credit points can be used to purchase and exchange various living materials. Everyone must work to obtain credit points. Once the credit points are cleared, they will lose the qualification to enter the dungeon.

In a sense, credit points are similar to currencies in real society, and they are the foundation for everyone's survival in this era.

However, there are also differences between credit points and currency. For example, everyone’s credit points cannot be traded. Parents with more credit points do not mean their children have more credit points. Parents cannot transfer their own credit points to their children.

In order to prevent malpractice, the computer will monitor the use records of each person's credit points. At the same time, the issuance of credit points is also fully executed by the supercomputer. The coalition government can only do regular maintenance and inspections to prevent bugs in the issuance process.

At the same time, credit points are also related to dungeon lottery qualifications and basic social security qualifications.

Pang Xuelin's parents had previously signed a ten-year work contract with the Planetary Engine Company under the coalition government to work on Shanghai No. 2 Engine.

Their work can enable Pang Xuelin to enjoy free food, education, housing and medical security, as well as gain the qualification to enter the underground city in advance.

Even whether grandparents can receive pensions normally is related to whether they can work normally.

And every year, they only have seven days of vacation to come back and reunite with their families.

This is not only the Pang Xuelin family, but also the living conditions of other Chinese families and even most families in the world.

From a certain point of view, this is an era where everyone is under heavy pressure, and it is precisely because of this pressure that human beings can complete the feat of repairing 12,000 earth engines and dungeons in 30 years.

If Pang Xuelin had a high enough authority or status, it might be possible to transfer his parents back to Jiangcheng to work.

But now, he is just a fifteen-year-old high school student, and he can't do anything, even if he wants to go to Shanghai to see his parents.

Because of the law, unless there are special circumstances, such as Pang Xuelin's participation in the Mathematical Olympiad winter camp, or Yao Bingxia's father was selected for the pilot space, minors are not allowed to travel across cities.

All Pang Xuelin can do is to prepare these life-saving bags in advance so that they can be rescued safely in a possible crisis.

...

In the following time, Pang Xuelin's life became regular again.

He left early and returned late every day, except for taking Yao Bingxia to and from school, the rest of the time was spent in the laboratory.

Du Jiaxiang is the director of the laboratory, and specially arranged four doctoral students for Pang Xuelin to help with the experiment, including Xiao Gao Gao Tianyi.

Pang Xuelin couldn't operate well, so he only needed to provide theoretical guidance based on the content of the paper, and these well-trained experimental dogs would naturally arrange everything properly.

The experiment went well.

Half a month later, Pang Xuelin successfully obtained a batch of single-walled carbon nanotubes with a purity as high as 99.8%. Although there is still a certain distance compared to Wang Miao's ultra-high purity of 99.99999%, Gao Tianyi and the others have been overjoyed.

Even Du Jiaxiang, although he was more optimistic about Pang Xuelin's experimental plan, did not expect that they would produce results so quickly.

Pang Xuelin is still a little dissatisfied. Although these single-walled carbon nanotubes can be used as battery polymer additives and raw materials for CMOS devices, they cannot be made into flying blade materials like Wang Miao and others.

The purity is still too low.

But it is enough to write a thesis.

It took a week for Pang Xuelin to use the existing experimental data and refer to the information provided by the system to successfully complete the writing of his first material science paper.

Then he handed over the thesis to Du Jiaxiang for polishing.

Du Jiaxiang returned it almost without changing a single word. In his words, this paper is excellent enough and does not need polishing at all.

At the same time, Du Jiaxiang also rejected the suggestion to sign the paper.

Pang Xuelin had no choice but to write his name on the corresponding author, and the first author wrote Gao Tianyi's name.

After all, during the experiment, Gao Tianyi played a great role and helped him a lot.

The remaining doctoral students who participated in the experiment were also added to the list of second authors by him.

This made Gao Tianyi and the others very excited. After all, everyone knew how significant this paper would be after it was published.

Under Du Jiaxiang's suggestion, Pang Xuelin submitted this paper to "Nature Nanotechnology".

During the days of waiting for a reply, life became calm again.

Pang Xuelin devoted himself to studying every day, and Gao Tianyi and the others continued to improve the experimental plan to increase the purity of single-walled carbon nanotubes.

However, as the time to enter the dungeon approached, many rumors appeared in the society.

Some people say that because the construction of the planetary engine is completed, human beings no longer need to do such hard work, and the government will gradually relax restrictions on various fields of society, especially the cultural field.

It is also said that after entering the dungeon, the credit point system will undergo major reforms, gradually stripping it of its relationship with social security, and endowing it with a more prominent currency attribute.

In a word, human beings are full of beautiful longings and imaginations about the upcoming underground city life, and everyone is tired of the never-setting sun hanging in the west and the endless labor.

In the afternoon, Pang Xuelin came out of the laboratory, came to the gate of Jiangcheng Middle School, picked up Yao Bingxia who was leaving school, and then rode back home.

"Brother Lin, grandpa and I will enter the dungeon tomorrow. I heard from grandpa that you plan to stay on the ground for a while longer?"

Pang Xuelin smiled and said: "Yes, I still have a lot of things to do at Jiang University. I guess I will enter the dungeon with my Jiang University classmates in the middle of next year!"

"Then remember to come and play with me when the time comes. I heard from grandpa that the houses we were allocated are not in the same area."

"Don't worry, when I enter the dungeon, I will definitely find you!"

The two talked and laughed, and soon rode their bicycles to the vicinity of the community.

At this moment, Pang Xuelin suddenly felt the road shake. Immediately afterwards, the asphalt road in front of him suddenly began to tear, the cracks grew rapidly, and the whole ground shook violently.

Rumble——

There was a loud noise, as if a giant beast from the depths of the ground had been awakened.

"ah……"

Yao Bingxia let out an exclamation.

"Xiao Xia, get out of the car!"

Pang Xuelin's face changed drastically, he stopped quickly, pulled Yao Bingxia past him, and ran to the open space on the other side of the road. After making sure that there were no buildings around that could hurt them, he stopped and looked at everything around him in horror.

An invisible force tore the land apart, and the ground shook violently. Pang Xuelin and Yao Bingxia couldn't stand still at all and could only sit slumped on the ground.

A tall building in the distance gradually tilted down, and then hit another building, and smoke and dust were everywhere.

In an instant, the house collapsed and the ground crumbled.

People on the street looked for places to hide, crying and shouting everywhere.

An unprecedented super earthquake swept through Jiangcheng.

The vibration lasted for nearly two minutes before it gradually stopped.

Pang Xuelin stood still, until Yao Bingxia's cries woke him up from all these nightmares.

"Woooo, Brother Xiao Lin, Brother Xiao Lin, woohoo, what shall we do?"
