As time passes, planets are orbiting the sun in circles. On the earth, the sun rises and then sets day after day. All this seems to have no change from the past hundreds of years or even billions of years, but everyone knows that human civilization is different at this moment.

The most critical scientific data brought back by Ye Luo from the South Gate Two Stars are like a needle of a heart. After it was injected into the dying human civilization, human civilization immediately burst out with amazing vitality.

The battlefield cleaning work, post-war reconstruction work, countless huge projects such as daunting, such as the post-war reconstruction work, were completed in just a few decades. Once again, a large number of commercial spacecraft sailed on the waterways between different planets, and large-scale energy collection bases were once again built on resource planets such as Jupiter and Saturn. The despair was swept away, replaced by vigorous vitality like grass sprouting in spring.

This situation has lasted for more than a hundred years. Although in a strict sense, the situation of human civilization has not been changed and the knot still exists, there is hope after all. Hope is such a magical thing that can turn decay into magic and make a dying civilization reenergize.

When the Central Academy of Sciences announced the report that "new energy has passed laboratory tests, and the dead knot is expected to be broken within 50 years" in major media of mankind, the entire human civilization fell into a sea of ​​joy.

Countless crowds gathered on the Human Square and gathered under the huge statue of the Head of Kavis to launch a grand celebration. This place truly became a sea of ​​flowers.

At this moment, no one cares about other people's origins or other people's nations. Whether it was subordinate to the inner solar system alliance or the outer solar system alliance in the past, what does it matter? After all... we are all human beings, unity and struggle together are the most in the interests of all of us. Isn't it?

Head of Carves, who had been looking at the sun and changed his direction as the sun moved, seemed to have a smile on his face at this moment.

The deeds of Head Kavis have long been well known. After the war, even those who were in a state of hostility with Head Kavis were impressed by Head Kavis' broad mind. Therefore, at the voting meeting after the war, the participants unanimously agreed to erect the statue of Head Kavis in the center of the People's Square, and use technical means to keep Head Kavis facing the direction of the sun, in order to commemorate the great contributions made by Head Kavis to human civilization. So far, the statue of Head Kavis has been erected here for more than a hundred years.

It can be said that Head of State Caves truly witnessed the rebirth of human civilization in the ashes.

The grand celebration lasted until late at night and gradually ended. At this time, the new head of state came to the museum where Ye Luo was stored and reported the news to Ye Luo.

"Ye Luo, you see, our human civilization has made major technological breakthroughs in the most critical places. We have mastered the latest energy use methods in theory, which will be more efficient than nuclear fusion. At the same time, we have also developed more advanced engines for spacecraft. With the cooperation of new energy and new engines, we will be able to build super-giant spacecraft with mass up to one million tons, which can carry thousands of people and speeds up to 30,000 kilometers per second, and even. With the further development of applied technology, this number will make a huge leap in the foreseeable future... This means that large-scale interstellar navigation has become possible for our human civilization. Our human civilization has not disappointed you, nor has your captain disappointed."

According to the speed of 30,000 kilometers per second, the round trip from the solar system to the South Gate Two Galaxy will take less than ninety years. Although this time is still very long, the average life span of human civilization is as high as 230 years old. Under such a background, it is completely affordable to take less than a hundred years to perform an interstellar voyage.

After all... interstellar navigation is not a playhouse. It is a comprehensive challenge to all branches of human civilization. The reduction of navigation time from nine hundred years to ninety years means a transition from "infeasible" to "feasible". Its significance is simply so important that it cannot be described in words.

"First of the People, thank you for coming here to tell me this news." Ye Luo replied. "I would like to express my sincere congratulations to you and our human civilization for this. But I still have another question. I would like to ask when will the spaceship that can be built for picking the captain home and when can we set off?"

"I just want to fulfill my promise, I just want to take the captain home, and everything else doesn't matter to me," Ye Luo said.

"Please rest assured that this day will not be too far away." The head of state said with a smile. "The spacecraft will set off in less than fifty years. After a maximum of one hundred and fifty years, you can accept the tribute from all of us humans in this solar system with your captain."

"Okay, thank you." Ye Luo said.

Time is still passing by little by little, and everything in human civilization is developing in a beautiful direction. However, as time goes by, people gradually discovered a very embarrassing point, that is, the limitations brought to the development of human civilization by insufficient population.

Development requires population, whether it is scientific research, engineering manufacturing, or the most basic energy mining, material transfer, etc., all require a large number of people as support. However, due to the trauma brought by previous wars and the psychological shadows brought to people by "dead knots", the population of human civilization has remained at a low level for a long time and has a faint downward trend. Although the return of leaves has changed this situation, in a short period of time, this situation cannot be completely changed.

Under the dual stimulation of the government's encouragement and the need for civilized development, a new wave of baby boom has arrived. In the past decade, it is expected that as many as one billion babies will be born into this world, and the birth rate will continue to increase. However, it takes time for babies to grow. They also need time for education and understanding the world. This situation cannot be rushed. They can only rely on the passage of time to slowly change this situation.

This kind of waiting is very uncomfortable for those who are anxious. During this period, I don’t know how many people, even senior government officials, and even the Head of State, have secretly sighed: “If our human civilization has 300 billion, no, even if it is only 200 billion, if we can have 200 billion people, how fast will our human civilization develop... Why do we still worry about the lack of manpower all day long…”

Encouraging childbirth has become a consensus in the whole society. Even a mother who gave birth to tens at one time was personally received by the head of state and was awarded the title of "Heroic Mother". It became a hot news for a while, and I don't know how many people envy it. With the support of various encouragement policies, I don't know how many couples hurried home to start a plan for creating a human being after finishing their day's work. This actually led to a series of depression symptoms in the various entertainment and catering industries, which triggered discussions among many people.

After all... there are so many star systems in this universe, so many planets are waiting for human civilization to explore and occupy. How can we do if the population is small...

Decades passed by again. Ye Luo, who had lived in the museum for nearly two hundred years, was grandly invited on this day, and the head of state personally accompanied him to the huge dock of Saturn Base. At this moment, hundreds of thousands of experts from various disciplines and a large number of journalists from various disciplines have gathered here at the Saturn Base, but they are not the protagonists today. The protagonists today are Ye Luo and the head of state, and there are also a huge team of 800 people.

The team gathered the most outstanding astronauts, scientists and logistics personnel. In addition, there are the most outstanding hibernation resuscitation experts and doctors from various disciplines. They will take the newly built "New Life" spacecraft today to launch the first large-scale interstellar voyage in the history of human civilization. They will sail from the solar system to the South Gate II Galaxy. In this process, they will verify many scientific conjectures and collect a lot of scientific data. In addition, they have one of the most important tasks, which is to take heroes home from the South Gate II Galaxy.

"We still remember the despair and suffering we experienced more than two hundred years ago. We have also personally experienced the rebirth and transformation of our human civilization over the past two hundred years... Once, our human civilization was only one step away from destruction. Once, we could only look at the stars in the sky helplessly. They seemed very close to us, but the fact is that the distance was enough to exhaust our entire life and could not cross it. But now it is different... We have built the spacecraft of the New Life, and we can carry out a large-scale interstellar voyage. So, please tell me who saved our human civilization from the abyss of despair. Who made our human civilization start a new life?"

After the head of state asked this question, the crowd below immediately burst into deafening cheers: "Weifeng, Weifeng"

"Okay" the head of state waved his hand vigorously, "Then let's set off now and take our hero home" to be continued.
