After eating breakfast, Wang Xiufang took a down jacket for Pang Xuelin from upstairs and said, "Xiaolin, the temperature has dropped to below zero today, you put on the down jacket and go out!" ”

Pang Xuelin was slightly stunned, but didn't say anything.

Just now he found out that there was a heating pipe in the house, and he could clearly feel the heat.

Because of the planetary engines, the climate and environment on the earth changed drastically before the earth set off.

However, it is now July, and the temperature in Jiangcheng is only about zero degrees, which surprised Pang Xuelin.

Pang Xuelin pushed the bicycle and went out with Yao Bingxia.

This community was originally supposed to be a villa area for retired professors to live in, and it has always been known for its quiet environment, cleanliness and tidiness.

But now, what Pang Xuelin sees is a dilapidated scene.

The lawns on both sides of the road are overgrown with dead grass, littered with dead branches and leaves, some of the courtyards are uninhabited, and the outer walls have been conquered by creepers, and no one has taken care of them.

There are many fewer residents in the community than in the real world, and I don't know where these people have gone.

But Pang Xuelin didn't have the heart to think about these issues.

When he looked at the west side of the community, the whole person froze in place, as if all his words and thoughts had lost the ability to function normally in front of this behemoth.

In his eyes, there was a metal mountain, this mountain occupied most of the sky, and the whole city was in its shadow, compared to the Jade Emperor Mountain, which was 237 meters above sea level, it seemed to be a small mound.

This is the largest man-made object ever seen by Pang Xuelin, and the largest man-made device he has ever seen before is the 50,000-ton geosynchronous orbit space station in the Martian world.

But now, that space station is like a small sampan in the sea, and this mountain is undoubtedly a giant aircraft carrier!

The crimson sun shone behind the engine, glowing blood-colored.

It's early in the morning and the sun is in the west, what a fucking world!

"Brother Xiaolin, what are you looking at?"

Yao Bingxia's voice made Pang Xuelin come back to his senses from the shock.

Pang Xuelin said: "No, it's nothing, Xiao Xia, this is the Jiangcheng No. 1 engine?" ”

Yao Bingxia was already surprised, nodded and said, "Yes, what's wrong?" ”

"Oh, no...... It's okay! ”

Pang Xuelin shook his head and said, "By the way, Xiao Xia, do you have a mobile phone, I want to go online to see it!" ”

After waking up, Pang Xuelin didn't see any communication equipment such as mobile phones, and before going out, his grandmother only prompted him to bring his schoolbag, but didn't let him bring his mobile phone.

Accustomed to the flow of information in the era of mobile Internet, without a mobile phone, he always feels that something is missing.

Yao Bingxia was slightly stunned, and said in confusion: "Brother Xiaolin, the mobile phone is so expensive, how can I afford it!" It's weird, how do you look weird today! ”

"Huh?"

Pang Xuelin was a little sluggish.

Is a mobile phone expensive?

Pang Xuelin quickly reacted, in this world, human beings should invest all their resources in the construction of the earth engine, and the production capacity of civilian industrial products has been compressed to the extreme, so it seems understandable that mobile phones are expensive!

And when he went out and passed by the study in the morning, Pang Xuelin found that there was no computer in his grandfather's study.

He hadn't thought much of it at the time, but now, it seemed to have some understanding.

"Oh, it's okay, let's get in the car, let's go to school first!"

Pang Xuelin stepped on the bicycle, Yao Bingxia sat in the back seat and grabbed Pang Xuelin's clothes.

Pang Xuelin rode like the wind, and soon took Yao Bingxia out of the community.

Along the way, Pang Xuelin found that the urban infrastructure of Jiangcheng as a whole is no different from the reality of 2019, but whether it is roads or buildings, it seems to have passed through decades of time and been dyed with traces of time.

The market seems to be very dilapidated, there are few shops that are open for business, and the restaurant industry, which was originally thriving in the previous life, has completely declined in this era, and occasionally I see one or two restaurants, most of which are Lanzhou ramen, Shaxian snacks and the like.

Everyone was in a hurry, and Pang Xuelin hardly saw pedestrians shopping leisurely.

Twenty minutes later, Pang Xuelin came to his alma mater, Jiangcheng Middle School.

The school looks the same as it did 30 years ago, except that the building was brand new back then, but now it has become a different face.

Pang Xuelin first sent Yao Bingxia to the junior high school, and asked her to go to the cafeteria to eat together at noon, and then went to the high school teaching building.

In the second (11th) class of high school, Pang Xuelin quickly found his classroom according to his memory.

The classmates were no different from their previous lives, the classroom was still noisy, Pang Xuelin silently walked to his place and sat down.

When he was in high school in the real world, Pang Xuelin was several years younger than his classmates, plus he was introverted and had good academic performance, so he was a special existence in the class.

No one can ignore him, but no one has friends with him either.

He also enjoyed himself, and spent most of his time in the classroom immersed in learning, which was a little transparent in the class.

In this world, Pang Xuelin's treatment seems to be similar, and after sitting in his place, no one talks to him.

Pang Xuelin didn't care, he found the textbook and flipped through it.

If you want to understand the world systematically, the information on the Internet is too complicated, and it is difficult to distinguish between truth and falsehood, but textbooks are a better choice.

Pang Xuelin found textbooks on history and politics, and he soon became obsessed with them.

……

The following is a chronicle of the Wandering Earth plane.

In 1977, Chinese astronomer Fu Jianming, after counting the state of solar activity in the last 1,000 years and detailed records of nearly 50 years, put forward the thesis that the acceleration of fusion in the solar core would produce a deadly helium flash, so that the sun would die, and rapidly expand and engulf the earth. This argument has not resonated internationally.

In 1980, NASA expert Terrence Brook organized a group to study the topic after reading Fu Jianming's paper.

In 1984, Fu Jianming and Terrence believed that helium flashes would occur within 400 years. This conclusion has been met with great skepticism in the scientific community.

In July 1995, Terrence Brook was indicted for embezzlement of NASA research funds, and the trial moved quickly. Within a month, Terrence Brook died of a heart attack. The Foundation was disbanded by the government.

In September 2000, Fu Jianming returned to China with all the research results and received government funding to continue his research.

In October 2003, a G5-magnitude solar coronal ejection hit the Earth, causing no more harm than the scrapping of a Japanese satellite. Fu's research group obtained more data.

In 2009, Fu Jianming's solar helium flash research team published a paper again, predicting that a solar storm in 2016 would seriously affect the Earth.

In 2010, a secret report was sent to the United Nations Security Council stating that China and the United States were secretly studying strategies to deal with the helium flash of the sun. The study caused a small international stir, and various countries that were able to do so began to secretly invest in the research.

In March 2014, Fu Jianming died of a ruptured advanced liver tumor in the hospital at the age of 60.

In 2015, Kazuo Nakata applied refusion technology to a spacecraft engine and successfully built the first refusion engine.

In June 2016, the coronal ejection storm of the 25th solar cycle hit the earth, and the solar storm exceeding the G5 level destroyed 40% of the civilian power transmission and transformation lines and communication facilities, and destroyed more than 50% of the civilian electronic instruments, and the global riot broke out. Space Biosphere 1, which is still in operation, was fatally damaged and six scientists were killed.

In September 2016, widespread unrest subsided, the population plummeted by 3%, and the economy suffered economic losses of more than $54.37 trillion (more than three times the GDP of the United States in 2015).

In October 2016, scientists confirmed that fusion at the center of the Sun was accelerating, based on observations from China's FAST telescope. Observations from large astronomical telescopes around the world are approximate.

In January 2017, under the leadership of the five major countries, the United Nations set up a helium flash response team, with scientists from various countries and experts from different industries joining the discussion. At this conference, Liu Xin met with Kazuo Nakata for the first time to discuss the feasibility of building a giant refusion engine.

In January 2018, the year-long debate over the UN helium flash response team continued. After Liu Xin and others submitted a plan to start the "Wandering Earth", the group split into the spaceship faction and the planetary faction, and started a new debate.

In February 2018, the United Nations began to assemble global space forces to prepare for the construction of the "Navigator" International Space Station, which is planned to be completed in 30 years. The space station will provide early warning, pilotage and communication support for the Earth during the voyage.

In July 2018, the latest observational data indicated that a helium flash was highly likely to occur around 2100.

In 2019, the United Nations decided to focus on the feasibility of planetary engines, and the U.S.-backed spacecraft was sent out of the team. The United States researches and builds new types of spaceships for space colonization.

In October 2019, the hackers obtained the U.S. government's research plan and released it to the public. The proposal states that the cost of space migration is very high, so only people with a fortune of more than $30 million will have the opportunity to participate in the ticket lottery. Panicked American society once again erupted in mass riots. The U.S. government was forced to abandon the spaceship colonization program.

In 2020, countries around the world ceded some military power to the United Nations, and the United Nations announced the "Wandering Earth" plan to the world.

The Spaceship faction began to smear the "Wandering Earth" project in the major media. For the first time, they used the term "neocentric theory" and accused the proponents of planetary engines as stubborn and superstitious supporters of "neocentricism". The controversy over the planetary faction and the spaceship faction spread to the people.

In 2020, the Human Family Planning Project was launched, and the United Nations plans to reduce the population from 7 billion to 5 billion within 30 years, with only one in three newlyweds in the world having the right to have children.

In 2021, the human civilization backup project was launched.

In 2022, the planetary engine supporting dungeon project will be launched. It was led by the Chinese government, which has experience in the construction of large-scale infrastructure projects.

In 2025, the United Earth Government was announced. At the same time, the Earth Security Force, led by the coalition government, was formally established.

In 2029, the construction of the circum-equatorial steering planetary engine was completed.

On May 4, 2029, the first set of planetary engines was launched, and mankind entered the era of braking. The United Nations plans to stop the planet completely within twenty-five years.

In 2032, the project to expel the Moon from the Earth-Moon system will begin.
