In the blink of an eye, the earth has been in the eleventh year of the new era, and nearly twelve years have passed since the end of the war between the Gaia civilization and the earth civilization.

Twelve years, this is not a short time, which is enough for a new generation of people to grow rapidly during this period, and the same is true for the Earth in the new era. With the twelve years of stable and rapid development, the people on earth have completely wiped out the trauma of the war that year and showed a prosperous scene.

The first president of the Earth Federation government had already stepped down last year. The first president, who was destined to leave a strong mark in human history, finally had his second term expired and he retired from the position of president. And the Asian man who succeeded him as the third president, or to be precise, was an "Chinese". However, for more than ten years, the concept of the once-country on Earth has basically faded. With the prosperity of the Earth Federation and the various conveniences and superior life brought to mankind by the development of technology, the country has long been replaced by the current Earth Federation in the minds of all Earth people.

Compared with the first president, the new president's methods are more moderate. Of course, this is also the result of history. After all, the current Earth Federation has been stable and the federal government has long been deeply rooted in the hearts of the people. Those national separatists who attempt to subvert the government have long been wiped out under the iron fist of the first president. With the development of society and the needs of the government, the adjustment of the president's primary work direction is also an inevitable result.

Meng Lin sat in a driverless car, looking at the scenes passing by on both sides at a rapid pace, surrounded by picturesque scenery. Since the reconstruction of the earth, the Federal Academy of Sciences has made detailed plans for this in order to consider the environmental protection and development of the earth's homeland. The federal government also did the same in the governance process. In twelve years, the earth's ecology has been restored to a very good environment. Even ordinary citizens can enjoy natural and beautiful living conditions. Those metropolises that were crowded like reinforced concrete forests in the early years no longer exist, and are replaced by the exquisite buildings in front of them that are hidden in the beautiful scenery.

In the past twelve years, the earth's population began to recover after a significant decrease, although the recovery ratio was a bit amazing. In just twelve years, the total population of the earth has almost returned to the pre-war level. However, with the development of science and technology and the implementation of the policies of the Earth Federation, the earth is not as crowded as before, especially in the metropolis where Meng Lin is now, it was absolutely impossible to drive cars without any obstacles like now.

On the one hand, this is the result of the global balanced adjustment of population, and on the other hand, it is because the developed technology of unmanned cars are directly controlled and dispatched by the city's central intelligent brain. As long as the passengers sit in the unmanned cars and input the destination to the intelligent brain, the data will be received simultaneously by the central intelligent brain, and then automatically allocated according to the road conditions and driving speed to quickly arrive at the destination in the shortest and most convenient time, thus avoiding the previous congestion.

Another reason is also important, that is, although the total population of the earth has returned to the pre-war level, in fact, the current population on the earth is only 70% of the total population. Another 30% of the population lives on the lunar base or Pluto base. Even the newly developed Mars base, and with the accelerated development of Mars, humans have initially completed the construction of Mars into a life planet on the new earth, thus having the same ecological environment as the earth.

Moreover, as humans enter the universe civilization, human exploration into the universe has become increasingly strong. This situation is particularly prominent among the new generation of young people, and they leave Earth and go to Mars to enjoy another "alien" life that is slightly different from Earth. This is also a great temptation for people of other ages.

What's more, the federal government is currently encouraging people on Earth to explore and build other planets, which further promotes this phenomenon. Therefore, the actual proportion of the population living on Earth is declining year by year, and coupled with the development of earth's resources and technology, the living standards and comfort of human beings on Earth are also constantly improving.

Everything around has completely changed. Meng Lin came to this city more than ten years ago, but now he can't find any familiar shadows. Although there are beautiful communities and picturesque scenery everywhere, Meng Lin can't help but feel a little regretful in his eyes.

Meng Lin just returned to Earth last month. Since he followed Su Yichen and others to Pluto Base many years ago, he has been at Pluto Base for more than ten years. For more than ten years, due to work reasons, Meng Lin has not returned to Earth, but lives on Pluto.

Not only that, Meng Lin became a relative on Pluto six years ago. He was a father five years ago and now has two sons. It can be said that compared to the already unfamiliar Earth, Pluto has become Meng Lin’s real home. This time he returned to Earth was a job transfer from the Federal Academy of Sciences. Considering that Meng Lin and his wife worked so long on Pluto, and even their children had never returned to Earth, the Federal Academy of Sciences specially transferred them back.

When returning to Earth, the most exciting thing is of course their two children. Children who have been growing up in Pluto since they were born only telling the concept of the earth from their parents. When they return to Earth, the scenery completely different from Pluto quickly attracted them and made the children very excited.

As for Meng Lin and his wife, the Federal Academy of Sciences has provided them with a very good home in this city, and they also gave them a full month off. First, they were to accompany the children who had returned to Earth for the first time, and second, they were to re-familiar with this earth that had already made them unfamiliar.

However, Meng Lin was a person who couldn't stay idle. He could tolerate short-term vacations, and his long-term idleness made him feel as uncomfortable as his body was rusting a little bit. After accompanying his wife and children around, Meng Lin became a little bored soon. After several requests, the Federal Academy of Sciences quickly re-arranged a new job for him. His wife went to the institute under the Academy of Sciences, and Meng Lin was arranged to work in the branch of the Federal Academy of Sciences in this city. Today is when he first went to report.

The unmanned car soon arrived at the destination he was going to, the branch of the Earth Federal Academy of Sciences. Currently, there are five branches of the Earth Federal Academy of Sciences, and this is one of them.

The car automatically and smoothly stopped at the designated berth and got out. Meng Lin clicked on the portable intelligent brain on his wrist, and a three-dimensional structural diagram of the branch of the Academy of Sciences appeared in front of him. He looked up at the branch gate not far away. Meng Lin looked at the location of the office to report, then closed the intelligent brain and walked towards the door.

The Federal Academy of Sciences Branch has no guards. The gate is empty, surrounded by green forests and large lawns. But if you think this is a place where you can come and go freely, it would be a big mistake, because before the unmanned car set off, the city's central intelligent brain has connected the intelligent brain system of the Academy and made detailed filings for visitors. Even the moment Meng Lin arrived, the intelligent brain system of the Academy of Sciences scans the visitors' information from all directions. Once a problem is found, a defensive robot, including the armed guard of the Academy of Sciences, appeared soon.

He stepped into the door and followed the route I remembered Meng Lin went to the third floor and soon found the place he was going to. When he knocked on the door, a steady middle-aged man's answer came from the door. He pushed the door open and saw a man busy sitting at the desk.

"Dr. Meng?" The other party temporarily put down the documents in his hand, stood up with a smile, and walked to Meng Lin a few steps and stretched out his hand, "I thought you would have to wait a few days before you report it. I didn't expect it to come so quickly, sit down."

"Hello Dean Tang. I've been back for some days. The yard asked me to have a good rest, but you also know how people in our field can be idle?" Meng Lin smiled and shook hands with Tang Wei, and explained briefly.

Tang Wei nodded with a smile: "That's right, it's actually the same when I first came back, I couldn't stay idle than you."

"Director Tang also came back from the base?" Meng Lin asked in surprise. As an old man at Pluto Base, Meng Lin has been in Pluto Base for quite some time. It can be said that he is one of the longest people in Pluto Base. However, he has not found any information about Tang Wei in his memory, unless Tang Wei is Pluto who has only been in recent years. It can be seen that Tang Wei's position in the Academy of Sciences, even if he has never seen him, he should have heard of it.

When Tang Wei saw Meng Lin's expression, he knew that he had misunderstood. He smiled and replied that he was not at Pluto Base before, but at the Moon Base.

"Moon Base?" This surprised Meng Lin a little because the Moon Base is the headquarters of the space fleet. According to his knowledge, Tang Wei is a very well-known scholar. How did he run back to the Moon Base? Was he responsible for the military's scientific research before?

"Tea or coffee?" Tang Wei did not explain immediately, but instead asked him what he wanted to drink.

Meng Lin asked for a cup of tea. Although small jobs like making tea have long been replaced by household robots, Tang Wei is obviously a nostalgic person. He went to the side to make water and make tea. After a while, a pot of good tea was brought up.

"Try this white tea, which was given by an old friend, is very good." Tang Wei said with a smile after making a cup of tea for Meng Lin.

After tasting it, this white tea is indeed good. Although it has a complete ecological balance circle at the Pluto base, it is necessary to drink such good tea on the earth. Meng Lin deeply agrees with this.

"I used to work at the Earth Alliance headquarters and was a colleague with Dr. Ilena." After taking a sip of tea, Tang Wei explained.

After hearing this, Meng Lin suddenly realized that the Earth Alliance was later called the predecessor of the Earth Federation today, but in fact, those who have experienced the years knew that there was a huge difference between the two. The Earth Alliance was a temporary alliance organization established to resist the Gaia civilization that invaded the Earth. Its organizational structure was mainly based on the United Nations at that time, and it absorbed personnel from various government agencies, including some scientists and scholars.

However, this Earth Alliance died in name only after the outbreak of the war, and the scientific research institutions affiliated to the Earth Alliance were completely destroyed in the war. Later, after the establishment of the Earth Federation, most of the personnel belonging to the Earth Alliance in the early years entered the federal agencies, and the scientists of its scientific research institutions were also absorbed into the Federal Academy of Sciences.

The most famous of these scientists is Dr. Ilena, a beautiful and charming lady, the female scientist known as the goddess of astrophysics, is now the vice president and member of the committee of the Federal Academy of Sciences. If nothing unexpected happens, she may be the first female president of the Federal Academy of Sciences.

In the war between Earth civilization and Gaia civilization, Dr. Ilena suffered a lot and was even captured by Gaia civilization. Because after the war began, Dr. Ilena was sent to the headquarters of the Moon Base as an outstanding astronomical physicist to assist the fleet in defending the earth. However, unexpectedly, the attack power of the Gaia civilization was so strong that the space fleet built by the Earth civilization was almost wiped out in a short period of time. The highest commander of the fleet committed suicide and the moon base was forced to surrender.

After the war, the people at the Moon Base regained their freedom. As losers and prisoners, these surviving people were not discriminated against, but were regarded by the federal government as the most heroic figures of humanity on earth. The most famous of them was Dr. Ilena, who was worshipped and respected by many people.

Unexpectedly, Tang Wei, who was sitting in front of him, was also one of those people back then, and was even a colleague of Dr. Yilena, which surprised Meng Lin. However, Tang Wei looked like a middle-aged man. If calculated based on the time at that time, his age should be quite large. This is also normal for the current earth. With the development of technology, human life has begun to increase significantly. Judging from the current medical perspective, there is no problem with the average life of ordinary people exceeding 120 years old. If transplant technology is added, it is possible to live to 150 years old, and hibernation technology is becoming more and more mature. If hibernation is available, then life will last for hundreds or even thousands of years. Theoretically speaking, it is no problem.

In addition, Meng Lin knew better than ordinary people that he had a set of life-saving equipment at the Pluto base. This unique life-saving equipment could even break the limits of human life, thus making humans "rejuvenate". Of course, this is the highest secret of the Earth Federation, and the number of places that can use this set of equipment every year is extremely limited. At least before human science completely cracks the mystery of life, ordinary people are just a luxury for it.
