As time passed, the planets circled around the sun, and the sun rose and set day after day on Earth. All this seems to have changed from the past hundreds or even billions of years, but everyone knows that human civilization at this moment is not the same as before.

The most critical scientific data brought back by Ye Luo from the South Gate two-star system was like a shot in the arm, and after it was injected into the dying human civilization, the human civilization immediately burst out with amazing vitality.

Countless daunting projects such as battlefield clean-up and post-war reconstruction were completed in just a few decades, and once again a large number of commercial spacecraft sailed the shipping lanes between different planets, and large-scale energy harvesting bases were once again being built on resource planets such as Jupiter and Saturn. The despair was swept away, replaced by a vigor that sprouted like grass on a spring day.

This has been going on for more than a hundred years. Although the situation of human civilization has not changed in the strict sense, and the dead knot still exists, there is hope after all. And hope is such a magical thing, it can turn decay into magic, and can re-energize a dying civilization.

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

Countless crowds gathered in the Piazza de la Human, gathered under the huge statue of the head of Cavis for a grand celebration. It truly became a sea of flowers.

At this moment, no one cares about someone else's origin or other people's ethnicity. Either previously affiliated with the Inner Solar System Alliance or affiliated with the Outer Solar System Alliance. Does it matter? After all...... We are all human beings. Stick together. It's in the best interest of all of us to work together, isn't it?

Führer Cavis, who had been looking at the sun and changing the direction he was facing as the sun moved, seemed to have a smile on his serious face at this moment.

The deeds of Führer Cavis have long been known, and after the end of the war, even those who had previously been in a state of hostility with Führer Cavis were succumbed to Führer Cavis's broad mind. So, on top of the voting meeting after the war. The participants unanimously agreed to erect the statue of Führer Cavis in the center of People's Square, and to commemorate the great contribution made by Führer Cavis to human civilization by means of technology to make Führer Cavis face the direction of the sun all the time. By now, the statue of the Führer of Cavis has been erected here for more than a hundred years.

It can be said that Führer Cavis truly witnessed the rebirth of human civilization.

The grand celebration lasted until late at night, and it was at this time that 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 scientific and technological breakthroughs in the most critical places. We have theoretically mastered the use of the latest energy sources, which will be more efficient than nuclear fusion. At the same time, we have also developed more advanced engines for spacecraft, and with the cooperation of new energy sources and new engines, we will be able to build super-giant spaceships with a mass of up to one million tons, can carry thousands of people, and can reach speeds of up to 30,000 kilometers per second, and even with the further development of applied technology, this number will be greatly improved in the foreseeable future...... This means that large-scale interstellar voyages have become possible for our human civilization. Our human civilization did not disappoint you, nor did it disappoint your captain. ”

At a speed of 30,000 kilometers per second, the round-trip voyage from the solar system to the South Gate two galaxies would take less than 90 years. Although this time is still very long, the average life expectancy of human civilization is as high as 230 years at this moment, and in this context, it is completely affordable to spend less than 100 years on an interstellar voyage.

After all...... Interstellar navigation is not a masterpiece, it is a comprehensive challenge to human civilization in all sub-disciplines. Reducing the voyage time from 900 to 90 years means a shift from "not feasible" to "feasible". It's too big to put into words.

"Führer, thank you for coming to tell me the news." Ye Luo replied, "In this regard, I would like to express my heartfelt congratulations to you and our human civilization. But I have one more question, and I would like to ask, when will the ship that can be used to take the captain home be built, and when will we be able to depart? ”

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

"Rest assured, that day is not too far away." The Führer smiled and said, "It won't take more than fifty years for the ship to depart, and in a hundred and fifty years at most, you will be able to join your captain in this solar system to receive the salute of all of our humanity." ”

"Okay, thank you." Ye Luo said.

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

Development needs a large number of people, whether it is scientific research or engineering manufacturing, or the most basic energy extraction, material transfer, etc. However, because of the trauma caused by the previous war and the psychological shadow brought to people by the "dead knot", the population of human civilization has maintained a low level for a long time, and there is a faint trend of decline. Although the return of Ye Luo has changed this situation, it will not be completely changed in the short term.

Under the dual stimulation of the government's encouragement and the needs of civilization development, a new wave of baby boom has arrived, in the past ten years, it is expected that more than one billion babies will be born into the world, and the birth rate is still increasing, but the growth of babies takes time, they receive education, and it also takes time to understand the world.

During this time, I don't know how many people, even high-ranking government officials, and even the head of state himself have secretly sighed: "If our human civilization has 300 billion, no, even if it is only 200 billion, if we can have a population of 200 billion, then how fast will the development of our human civilization be...... Why should we worry about a lack of manpower all day long......"

Encouraging childbirth has become the consensus of the whole society, and even a mother who gave birth to ten twins at one time was personally received by the head of state and was awarded the title of "heroic mother", which became hot news for a while, and I don't know how many people envied it. With the support of various incentive policies, I don't know how many couples rushed home after a day's work to start a human creation project, which led to a series of depression symptoms in various entertainment and restaurant industries, and sparked many discussions for a while.

After all...... There are still so many star systems in this universe, so many planets waiting for human civilization to explore and occupy, how can you do it if the population is small......

Decades flew by again, and Ye Luo, who had lived in the museum for nearly two hundred years, was solemnly invited out on this day, accompanied by the Führer himself to the huge dock at the base of Saturn. At the moment, there are hundreds of thousands of experts in various disciplines and a large number of journalists gathered here at the base of Saturn, but none of them are the protagonists of today. Today's protagonists are Ye Luo and the Führer, as well as a huge team of eight hundred people.

The team brings together the best astronauts, scientists, and logisticians, as well as the best hibernation and resuscitation specialists and doctors from various disciplines, who will embark on the first large-scale interstellar voyage in the history of human civilization aboard the newly built "Newborn" spacecraft today. They will sail from the solar system to the South Gate Galaxy, and in the process, they will verify a lot of scientific conjectures, collect a lot of scientific data, and in addition to that, they have the most important mission, which is to take the hero home from the South Gate Two Galaxy.

"We still remember the despair and suffering we experienced more than 200 years ago, and we have also experienced first-hand the rebirth and transformation of our human civilization over the past 200 years...... Once, our human civilization was only one step away from extinction, and once we could only look helplessly at the stars in the sky, they seemed to be very close to us, but the truth is that the distance is enough to exhaust our lifetime and cannot be crossed. But now it's different...... We have built the new spacecraft, we have been able to carry out a large-scale interstellar voyage, so please tell me, who saved our human civilization from the abyss of despair, who is it that has allowed our human civilization to start a new life? ”

After the Führer asked this question, the crowd below immediately erupted in deafening cheers: "Wei Feng, Wei Feng!" ”

"Good!" The Führer waved his hand vigorously, "Then let's go now and take our hero home!" Go home! (To be continued.) )

It's better not to use the gift coin, as we all know, although the rainbow book has a good reputation, but the subscription results have been dismal, and this kind of niche science fiction text, in addition to relying on this electronic remuneration, there is no other channel, but the existence of the gift currency makes this achievement even worse......

The bonus policy of the starting point has been criticized because if you subscribe with a bonus...... The author will not get a penny. But as an ordinary author, Rainbow has nothing to do about this, but please everyone, if you have the conditions, don't use the gift coin, please, please.
