The height of the shuttle was slowly rising, and there was almost silence in the cabin.

All the passengers had their own hearts and minds, looking out at the withered yellow earth. Everyone who has been here for so long will always have a little feeling.

Even on this planet, humans can't breathe any air freely, and they have to resort to spacesuits to survive. But standing on this piece of land, you can still feel the warmth of the former home planet.

A living planet.

Perhaps, it will never come back......

Thinking about it like this, there is a hint of parting emotion.

"Everyone, don't be so sad, there are more stories in the universe waiting for us to explore!" Diplomat Wang Junpeng suddenly said: "The matters related to the Gliese civilization have come to an end for the time being, and everything that follows should be handed over to them to be responsible for themselves." Flowers in a greenhouse are always just flowers, and if they can't withstand a storm, they won't become towering trees. ”

"There's a story in their history, and they should be able to learn a lesson."

Hearing this, many people raised their heads again and discussed in whispers, and the atmosphere in the entire cabin seemed to be revitalized all at once.

Yes, the Gliese civilization is divided into three. Some of them went to distant alien planets, others entered the virtual world, and the last small part tried to start another era of their own under the education of humans.

Even if it is to restart civilization, it can be quite difficult.

But what civilization has not had a difficult path to development?

Even human beings themselves are trembling and walking a tightrope, for fear of accidentally falling into the abyss.

Recalling the bits and pieces that happened on this planet, Wang Junpeng was full of emotion, he fulfilled his diplomatic obligations on this planet again and again, and he also grew a lot and changed a lot. Even from a young man to a middle-aged person, all the youth has passed on this planet.

Of course, even if you are middle-aged, you still have the spirit to be as good as young people...... This is the pride of their generation!

"The Wandering Project is finally about to begin, and we, the branch of the human race, can't afford to lag behind the Golden Age!"

"Instead of lamenting that the road is difficult, it is better to set off immediately!"

Listening to the discussion of many colleagues around him, Wang Junpeng couldn't help but smile slightly.

Seven years ago, people received a series of electromagnetic wave information, and after analysis by information experts, it was actually sent from Barnard Star, where the "Golden Age" is located!

This series of electromagnetic waves informs in detail about the development of the human branch of the "Golden Age".

The landing site of the Golden Age, also known as Barnard Star, is relatively close to the Sun and has been developing for five or six hundred years longer than the "Earth Age".

After five hundred years of smooth development, they have completely understood the heritage of the earth civilization, which is already comparable to the previous earth civilization, that is, it has developed to the level of the second-level civilization.

Fortunately, this branch of humanity, having learned the lessons of the past, is still in a thriving state, and they are seeking a new direction of development to avoid the same trough of mediocrity as the civilization of the earth.

Of course, the humans of the Earth Age also have their own experiences, whether it is high-dimensional fragments, the Bozman quantum consciousness converter, or the universal factory of the Gliese people, they can greatly erase the gap between the two sides.

"In particular, 13 universal factories can significantly speed up our development. In fact, our productivity and unique technology are not inferior to those of the Golden Age...... Anyway, when we send this information, the Golden Age will definitely be scared! ”

Even though the two branches of humanity are so far apart that it is difficult to even communicate with each other. But who is willing to be weaker than the other?

Wang Junpeng thought as he looked at the distant sky. At this height, the outline of the planet is already very obvious, and the stars become extremely dazzling, and this kind of immensity from the planet will not get tired of seeing it no matter how many times you look at it.

Good luck to you guys, Gliese civilization......

Over the past 100 years, even the transport shuttle has improved for several generations, making it more comfortable, safer and faster. After a six-hour voyage out of the atmosphere, the shuttle turned on its ion engine and headed for the direction of "Kunlun Mountain......

At this time, almost all the passengers got rid of the parting mood and leaned on the glass windows one by one and looked around. From a distance of tens of thousands of kilometers, you can see the stars in the interstellar port, busy space elevators, large and small spaceships, some transport spacecraft, and some armed frigates loaded with various weapons, which are in formation exercises.

Mount Kunlun, a giant mountain floating in space, the true heart of the wandering plan!

Yes, Kunlun Mountain, the next generation of super motherships!

At this moment, everyone cheered quietly, radiating an emotion called pride.

Even compared to the planet, it's still so small. However, it is so great that it embodies the hard work of a large number of scientific research workers.

Humans are not only ten or a hundred times stronger than when they first came here, but ...... A thousand times, ten thousand times!

The design model of the carrier was changed again and again, and the design time was much longer than the construction time, and finally settled on the cylindrical design concept, with a rated tonnage of one billion tons. A billion-ton spaceship carrying 12 million people!

Even 7 years ago, because of some scientific and technological information about the Golden Age, it was slightly changed, and the entire tonnage was designed to be larger.

When all the details were designed, the 13 universal plants were fully operational, and the construction has been completed in just over 20 years, and is now in the final commissioning stage.

Wang Junpeng couldn't help but discuss it with a colleague around him: "We should officially start the journey in five years." ”

"yes, I don't know where I'm going."

"I guess I'm going along the cosmic strings...... With the material recycling capabilities brought by the Kunlun Mountain and the Universal Factory, we can sail in the starry sky for more than 10,000 years. ”

An electronic sound suddenly sounded from inside the spacecraft, "Drop-the docking of the ship will begin in five minutes, please fasten your seatbelts and sit in your seats." Each crew member checks the operation of the spacecraft and does a good job of docking. ”

……

At this moment, Zhang Yuan is at the tail of "Kunlun Mountain", checking the latest engine system.

The engine of a spaceship is the most important thing, especially this gigawatt mothership, and if you want to push it, you need a powerful power system.

So far, humanity's strongest energy source is still only nuclear fusion, and there is still a long way to go before mass production of antimatter. In this case, how to improve the specific impulse of the engine has become a crucial research difficulty.

"Kunlun Mountain" abandoned the original rough propulsion method of a single huge engine room, and instead adopted the distributed propulsion of small nuclear fusion devices.

The propulsion of a single engine brings too much concentrated driving force, which is easy to cause metal fatigue and elastic deformation of the keel, but the driving force of multiple engines is more dispersed, which basically eliminates this kind of phenomenon.
