Nandez and Lu Kang were chatting about what had happened in the past hundred years, and above the Earth in the solar system, a spaceship was flying slowly above the Earth.

"The city has been completely deserted, and it is hard to imagine that this is the former Huangjing Town."

Inside the spaceship, Qin Yi is overlooking the earth below, for a hundred years, the earth has been implementing the strategy of recuperation, so in the past hundred years, there has been no trace of human beings on the earth at all, and everything has returned to the most primitive and natural state.

Without human footprints, the earth's ecological environment is recovering very quickly.

After the last citizen of the Earth Federation withdrew from the earth, everything on the earth returned to the original natural state, and the original prosperous city, because there was no human intervention and maintenance, in a hundred years, the high-rise buildings in the city fell down.

The city was in ruins, and all kinds of plants grew very rapidly, and soon the cities were once again transformed into a world of animals.

The same is true of Huangjing Town now, riding on the spaceship and overlooking the land below, it is lush and full of dense jungles, and only a few places can still see the remains of some high-rise buildings.

"Haha, our spaceship headquarters is still there, but it's crawling with all kinds of vines and plants, if it weren't for its special appearance, it really wouldn't be recognizable."

Qin Yi's side, Lu Qingwei seemed to have discovered something, pointed to a behemoth on the ground below and said with a smile.

Qin Yi looked in the direction he was pointing, and recognized from the appearance of the vines and plants that this was the spaceship building of the headquarters of the Galaxy Technology Group that he had built when he was on Earth.

"Boss, shall we go down for a walk?"

Liu Peiqiang seemed to remember the years all of a sudden, and proposed to go down for a walk.

"Okay, let's go down and take a look."

Qin Yi thought about it and nodded and said.

Soon, the spacecraft slowly descended to the plaza in front of the spacecraft headquarters building, which had been a huge cement square and was now also overgrown with tall weeds.

Cement also has a lifespan, generally only a few decades, a hundred years, under the wind and sun, most of the cement on the square has cracked, from which all kinds of weeds and trees have grown.

The spaceship that Qin Yi, Lu Qingwei, Liu Peiqiang and others were riding finally found a place to stop, and soon, Qin Yi's security personnel came down first, using laser cutting weapons to clean up the surroundings, and at the same time driving away poisonous snakes, spiders and other things hidden in the grass.

Qin Yi walked out of the spaceship and took a deep breath of the air above the earth, which was very fresh, with a trace of grass and trees, without a trace of pollution from the footprints of human civilization.

"I wonder if I can go in and have a look?"

Lu Qingwei looked at the spaceship headquarters building in front of him, and immediately found the location of the main entrance, looked at the vines and plants crawling over, and even thought about entering to have a look.

"Don't enter, it's already a dangerous building, maybe it will fall down at any time."

Qin Yi smiled and shook his head and said, looking at the huge building, as the spaceship landed, many small animals inside were frightened.

All kinds of birds flew out of it, pigeons, swallows, owls, eagles, sparrows, etc., and Qin Yi immediately found that there were more than ten kinds of birds flying out.

"Qin Yi, when will we move back to the earth, the ecological environment of the earth has been restored very well, the ice in the North and South Poles has been restored, and the vegetation coverage rate on the earth is as high as 90%, and even the former Sahara Desert has become a dense jungle."

Lu Qingwei nodded, then thought about it and proposed.

"It's still too early, wait for the earth to rest for a few hundred more years."

Qin Yi shook his head slightly, for the origin of the earth, Xinghan's side has truly set up the highest level of protection.

On the whole earth, except for the Great Wall, the Forbidden City, the Yanhuang Mausoleum and other famous historical and cultural landscapes that are regularly maintained, everything else is a return to the original nature, and in order to restore the earth's environment as soon as possible, the scientists on the Xinghan side are also trying their best to intervene appropriately, and the recovery speed of the earth's ecological environment is beyond imagination.

But Qin Yi didn't plan to migrate the core of Xinghan to the earth now, and was ready to continue to let the earth cultivate for a few hundred years, anyway, Xinghan was not bad for this living planet now.

Wandering around and walking very casually, Qin Yi and the others soon left Huangjing Town and continued to walk around some places on the earth that they were familiar with.

Looking at the once metropolises on the earth covered by a sea of green, only a little breath of human civilization can be found from the dilapidated buildings.

The bridges above the great rivers can now only see some wind-eroded and broken pillars, and the Yellow River, which has been muddy for thousands of years, has become extremely clear.

The Arctic glaciers that melted away a hundred years ago reappeared, and polar bears could still be seen on them, one by one, fat and strong, obviously without humans, their lives were really good.

"The vicissitudes of life~"

Qin Yi let out a long sigh.

Then one thing after another kept coming to mind, and the great changes in Xinghan in the past hundred years emerged.

Xinghan's territory has become more vast, with the solar system as the center, and the planetary systems around it with a range of thousands of light-years have been included in Xinghan's territory, with more than 100,000 stars.

In the direction leading to the sea of stars, almost all the stars have been included in the territory of Xinghan, from the original line, to the current three-dimensional coherence, like a long snake, opening its mouth wide, staring at the sea of stars, as if to swallow the sea of stars in one gulp.

With the expansion of the territory, the population of Xinghan is still maintaining a trend of rapid growth, with a huge population of trillions more than a hundred years ago, and now it has a huge population of tens of trillions, covering every corner of the entire huge territory.

Of course, none of this is a big deal, because it's bound to happen.

The rapid development of the population has inevitably promoted the continuous expansion of Xinghan, which requires a larger territory and more living planets to feed the larger and larger population.

The population is growing rapidly, the population base is getting bigger and bigger, and all kinds of talents are constantly emerging like carp crossing the river, among which Xinghan's science and technology have finally ushered in a major breakthrough after a hundred years of development, a breakthrough in energy technology.

Energy technology is not a technology with a high threshold, many civilizations can master this technology as soon as it develops to the level of level 2 cosmic civilization, and its most basic and entry-level is energy weapons.

Being able to research energy weapons is even if you have mastered energy technology, for example, the Earth Federation has now developed energy weapons, which can be regarded as mastering energy technology.

But this energy technology belongs to the kind of technology that is easy to learn and difficult to master, and it is easy to get started, but it is very, very difficult to really develop and develop to a higher level.

In the case of energy weapons, the attack distance and attack power of this energy weapon take an extremely long time to increase each level.

The Level 3 cosmic civilization in the Sea of Stars can only achieve a range of fifteen million kilometers in tens of millions of years, and if it is farther away, this power will plummet.

As for the Earth Federation's side, the attack distance of the energy weapon is even less than a million kilometers, and the power is also pitiful.

But these are all the first levels of energy weapons, the level of entry.

And now Xinghan's energy technology has developed to the second level, not only can it be used to attack, but also can use this energy for defense, and the energy shield technology has been developed.

Thinking of the energy shield technology, Qin Yi's heart couldn't help but feel excited, this technology was too important.

With the energy shield technology, Xinghan's space battleship can crisscross the battlefield at will, and there is no need to worry about being blown up.

At the same time, with the energy shield technology, Xinghan's plan to annex Xinghan can be put on the agenda, in the past, although Xinghan has developed a warp engine, but because there is no energy shield technology, Xinghan's space battleship and the level 3 cosmic civilization warship in the star sea will still be destroyed when they fight.

With the strength of Xinghan at that time, compared with civilizations like the Black Yan Empire and the Purple Moon Federation, the difference in strength was too great.

What's more, even if there is not much difference in strength, in the case of injuring the enemy by one thousand and losing eight hundred, Qin Yi will not be stupid to fight the other party.

Therefore, we can only wait slowly, and when this energy shield technology comes out, coupled with the warp speed engine technology, it is only a matter of time before the sea of stars is annexed.

"Let's go, go to the Xinghan Academy of Science and take a look at our energy shield technology."

Thinking of this, Qin Yi couldn't sit still, and as soon as his mind moved, he immediately gave an order, and the spaceship that Qin Yi was riding quickly left the earth and flew towards the void somewhere in the solar system.
