Nandez and Lu Kang are talking about what happened in the past century. On the earth of the solar system, a spaceship is slowly flying above the earth.

"The cities are completely deserted. It's hard to imagine that this is the former town of Huangjing."

In the spacecraft, Qin Yi is overlooking the earth below. For centuries, the earth has been implementing a strategy of rest and recuperation. Therefore, in this century, there is no trace of human beings on the earth, and everything returns 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 state of nature. The original bustling city, because there was no human intervention and maintenance, the century-old high-rise buildings in the city suddenly fell down. .

The city became a ruin, and all kinds of plants grew very fast, and soon the cities became animal worlds again.

The current situation in Huangjing Town is the same. Riding on the spacecraft overlooking the earth below, it is lush and full of lush jungles. Only a few places can still see some high-rise summer ruins.

"Haha, our spaceship headquarters is still there, but it is covered with all kinds of vine plants. If it is not in a special shape, it would really be unrecognizable."

Qin Yi's side, Lu Qingwei seemed to have found something, pointing at a behemoth above the ground and smiling.

Qin Yi looked in the direction he was pointing at, and recognized from the shape of the vine-covered plants that this was the spaceship building of the Xinghe Technology Group headquarters that he built when he was on the earth.

"Boss, shall we go for a walk?"

Liu Peiqiang seemed to remember the years of that year and proposed to go for a walk.

"Okay, just go down and take a look."

Qin Yi thought and nodded.

Soon, the spacecraft slowly landed on the square in front of the spaceship's headquarters building. This square was once a huge concrete square, but now it is also covered with tall weeds.

Cement also has a life span. Generally speaking, it is only a few decades. In the centuries, under the wind and sun, most of the cement on the square has cracked, and various kinds of cement have grown out of it. Weeds, trees.

The spacecraft that Qin Yi, Lu Qingwei, Liu Peiqiang, and others just managed to find a place to stop, and soon, Qin Yi's security personnel came down first, cut the weapon with laser, cleaned the surroundings, and also expelled Poisonous snakes and spiders hiding in the grass.

Qin Yi stepped out of the spacecraft and took a deep breath of the air above the earth. It was very fresh, with the green air of grass and trees, and there was no trace of pollution of human civilization.

"I don't know if we can go in and take a look?"

Lu Qingwei glanced at the spaceship headquarters building in front of him, and suddenly found the location of the main entrance. He looked at the vines covered with plants, and even thought of entering.

"Still not to enter, it has become a dangerous building, maybe it will fall at any time."

Qin Yi smiled and shook his head. He looked at this huge building, and as the spacecraft landed, many small animals inside were frightened.

A variety of birds flew out of it, such as pigeons, swallows, owls, eagles, sparrows, and so on. Qin Yi suddenly found that more than a dozen birds flew out.

"Qin Yi, when did we move back to the earth? The earth ’s ecological environment has recovered very well. The ice layers of the north and south poles have been restored. The vegetation coverage on the earth is as high as 90%, even the former Sahara desert. It ’s become a dense jungle. "

Lu Qingwei nodded, then thought and suggested.

"It's too early now. Let the earth rest for hundreds of years."

Qin Yi shook his head slightly. For the human origin of the earth, the Xinghan side really set the highest level of protection.

On the entire planet, except for the famous historical and cultural landscapes such as the Great Wall, the Forbidden City, and the Yanhuang Mausoleum, which are regularly visited and maintained, everything else is returning to the original nature, and in order to restore the earth's environment as soon as possible, scientists from Xinghan We also tried every means to conduct appropriate intervention, and the restoration of the earth's ecological environment was faster than expected.

However, Qin Yi does not intend to move the core of Xinghan to the earth now, and plans to continue to cultivate the earth for hundreds of years, anyway, Xinghan is not worse than this life planet.

I walked around and walked around very casually, and soon Qin Yi and others left Huangjing Town to continue walking around some places on earth that were familiar to them.

Looking at the once big city on the earth covered by the green ocean, we can only find a little bit of human civilization from the top of a broken building.

The bridge above the Dajiang River is only able to see some pillars damaged by wind erosion. The Yellow River, which has been turbid for thousands of years, has become extremely clear.

The Arctic Glacier, which had disappeared a century ago, reappeared, and the figure of polar bears can also be seen above. One by one, the fat and strong body are eaten. Obviously, without humans, their lives are really better.

"Changhaichangtian ~"

Qin Yi sighed.

Then things kept emerging in my mind, and the great changes of Xinghan over the past century.

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

In the direction leading to the Xinghai Sea, almost all the stars have been included in Xinghan's territory. From the original line, it has become a three-dimensional continuum, like a long snake, with its mouth widened, staring at it. Staring at Xinghai, it seems to swallow the Xinghai in one bite.

With the expansion of the territory, Xinghan's population still maintains a rapid growth trend. There was a huge population of trillions more than 100 years ago, and now it is already a huge population of tens of trillions, covering every one of the entire huge territory. corner.

Of course, these are nothing, because this is bound to happen.

The rapid population development will inevitably promote the continuous expansion of Xinghan. It needs a larger area and more life planets to feed an increasingly large population.

The population is growing rapidly, the population base is getting larger and larger, and various talents are constantly emerging like a river carp. Among them, Xinghan ’s technology has finally ushered in a major breakthrough after a century of development. Breakthroughs in energy technology.

Energy technology is not a technology with a very high threshold. Many civilizations can master this technology as soon as they have reached the level 2 universe civilization. Its first level and entry is energy weapons.

Being able to research an energy weapon is a mastery of energy technology. For example, the Earth Federation has now developed an energy weapon, which is also a mastery of energy technology.

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

In terms of energy weapons, the attack distance and attack power of this energy weapon require an extremely long time for each level.

The level 3 cosmic civilization in the Xinghai takes only tens of millions of years and can only achieve a range of 15 million kilometers ~ lightnovelpub.net ~ No matter how far away, this power will plummet.

As for the Earth Confederation, the attack range of energy weapons is only less than a million kilometers, and the power is small and pathetic.

But this is all the first level of energy weapons, the level of entry.

Now Xinghan's energy technology has developed to the second level. Not only can energy be used for attack, but also this energy can be used for defense. Energy shield technology has been developed.

Thinking of the energy protection cover technology, Qin Yi's heart just couldn't bear a burst of excitement, this technology is really too important.

With the energy shield technology, Xinghan ’s space battleships can be freely placed on the battlefield, and there is no need to worry about being knocked out.

At the same time, with the energy shield technology, Xinghan's plan to annex Xinghan can be put on the agenda. Previously, although Xinghan had already developed a curved engine, because of the lack of energy shield technology, Xinghan ’s space battleship and Xinghai When the battle of the level 3 universe civilization battleships, they will still be destroyed.

In terms of the strength of the Xinghan at that time, compared with civilizations such as the Black Yan Empire and the Purple Moon Federation, the strength was too great.

What's more, even if there is not much difference in strength, even if one hurts an enemy by one thousand and damages eight hundred, Qin Yi will not go fool with the other side.

So you can only wait slowly until the energy shield technology comes out, plus the speed engine technology, it is only a matter of time to annex Xinghai.

"Let's go to Xinghan Academy of Science and see our energy shield technology."

Thinking of this, Qin Yi couldn't sit still, and immediately gave an order when he thought about it. Qin Yi's spacecraft quickly left the earth and flew towards the void in the solar system.
