Xinghan Solar System Earth.

Qin Yi and Wen Xueying walked hand in hand over the Great Wall. The mountains and mountains and the Great Wall were like the dragons lying on the ground, magnificent and magnificent.

At this time, in the golden autumn of October on the earth, Qin Yi was in the position of the former Badaling Great Wall. Looking from the Great Wall, the mountains and mountains were golden. After more than a hundred years of rest, the earth ’s ecological environment was It has been greatly improved, and the vegetation coverage rate is so high that even the earth's oxygen content is constantly rising.

"I've been to the Badaling Great Wall many times. Although the environment is much better now and the scenery is much more beautiful, there are no tourists on the Great Wall, so I always feel a little missing."

Wen Xueying looked at the scenery in the distance, and then looked at the empty Great Wall, always feeling something missing.

She grew up on the side of the imperial capital. Naturally, the Badaling Great Wall didn't come here, but just a few hundred years later, she never came again.

This time, Qin Yi also brought her to the earth, and took a tour of the Great Wall of Badaling together to take a look and relax. This Great Wall is one of the few remaining human buildings on the earth.

The formerly bustling cities have now become a ruin drowned in lush jungles and weeds. The roads and bridges that used to be in all directions have been covered by weeds. There are no dams and no rivers above Yokohama Bridge.

Only the historic buildings such as the Great Wall and the Forbidden City are still maintained by Xinghan every year for maintenance.

"Less popular."

Qin Yi smiled and said, "Wait a minute, after the earth's ecological environment is better, we move to the earth, the earth's environment is still too fragile, and the time for cultivation is not enough."

"Woohoo ~"

Qin Yi's words had just fallen, and a tiger howling came from the mountains not far away. This sound was very loud, like a lion roar, and could be transmitted more than ten miles away. With the tiger howling, the group The birds fluttered in the mountains.

There are big wild geese flying southward in the sky, and there are sounds of clearing, and it seems to be responding to the tiger howling in the forest.

"Well, it's only been over a hundred years. I didn't expect that there were tigers in the mountains here."

Hearing the tiger howling, Qin Yi smiled.

In the past, the wild tigers on the entire earth were only Bengal and Siberian tigers, and other wild tiger populations have long since perished.

However, the population of tigers in history is actually very large. On the land of China China alone, there are Amur tigers, South China tigers, Xinjiang tigers, Bari tigers, Indochina tigers, Sumatran tigers, and Caspian tigers. To the major corners of the entire Asian continent.

But because of human over-hunting, the terrestrial beast was once threatened with extinction. Within a short period of time, the population and number of tigers rapidly declined and became endangered wild animals.

I did not expect that now, just for the earth to rest for more than a hundred years, the tiger population has actually been brought to the Badaling Great Wall. Before, there were no tigers here.

Qin Yi estimated that tigers are likely to be spread all over the entire Asian continent again, which is enough to show that the ecological environment of the earth is rapidly recovering.

"For these wildlife, a world without humans is paradise."

Wen Xueying said with a smile.

"Let's go. There's nothing to look at. Let's see the installation of the Earth's energy defense system in space."

I walked very casually on the Badaling Great Wall, and looked at it. Soon Qin Yi also remembered one thing. Today, the outer space of the earth is installing an energy defense system.

Over the past few decades, the Earth Federation has suffered and suffered extremely hard and slow development, while the Xinghan side is still developing at a terrible speed.

This energy technology has developed to the second level and mastered the energy shield technology. This technology can not only be used to protect space warships.

It can also be used to protect space ports, space factories, space buildings, etc. in space, and it can also be used to protect the planet of life.

After decades of research and development, Xinghan scientists have also developed energy defense systems that can be used to protect the planet of life.

The planet of life is very precious, but it is also very fragile.

Especially in the war of the interstellar universe, the confrontation between giant ships and cannons, huge energy attacks are vertical and horizontal in the void, it would be better if you stay away from the life planet.

If it is close to the life planet, or if it happens in the outer space of the life planet, then the life planet will basically be destroyed.

Powerful energy weapons are very powerful. In addition, there are nuclear weapons, space-based weapons, etc. Any weapon is enough to cause huge damage to the planet of life.

Especially when the enemy deliberately targets the planet of life, the planet of life appears more vulnerable. Once attacked, everything on the planet of life may be destroyed.

Facing such a situation, Xinghan scientists are also thinking hard about how to protect the planet of life.

Because Xinghan has mastered the technology of the warp speed engine, this space warship with a warp speed engine is out of control. Even if you have a huge army, it is difficult to defend every place and defend every life planet.

In the future, Xinghan will definitely meet more powerful opponents. It also has a powerful civilization that has mastered the technology of the speed engine. In the face of such a civilization, the first thing to think of is how to protect itself and the safety of the planet of life.

The emergence of the energy shield technology has also inspired Xinghan scientists. Based on this, after decades of research, scientists have also developed this energy defense system to protect the life of the planet.

In the outer space of the earth, Qin Yi's spacecraft flew out of the earth and soon began to orbit the earth.

Inside the spacecraft, Qin Yi looked at the outer space of the earth. Now the outer space of the earth is very empty and clean. Only a very small number of space buildings still remain. Other space factories, space cities, etc. have all been demolished.

Even the moon of the earth is protected, and no resources on the moon are mined anymore. Now Xinghan has no shortage of ordinary resources, and there is no need to mine the moon anymore.

In the open outer space, around the entire earth, there are very evenly distributed base stations of energy defense systems. This base station is not too large, and each base station is the size of a small spaceship.

Each base station is an energy source, and it is also a connection point. There are a total of 360 base stations around the entire earth. At this time, they have all been deployed.

"It will start soon ~"

Qin Yi's idea is connected to the virtual world. He always grasps the movements here, looks at the beautiful planet in the sky outside, and smiles and says Wen Xueying.

After hearing Qin Yi's words, Wen Xueying looked at the outer space of the earth, saw a beautiful planet, and saw a base station in space not far away.

I didn't wait too long. I saw that from a base station in outer space here, a few energy rays were radiated from these base stations, and soon they were connected to the adjacent base station lights.

Just a blink of an eye, in the outer space of the earth, at a speed that is visible to the naked eye, with these base stations as the center, the energy rays form a huge net, and the earth net is in it.

This is just the beginning. Soon, based on these lights, the majestic energy began to stir up. Gradually, a line formed by points and a surface formed by lines. A thin, silky light curtain began to appear. In the outer space of the earth, and in the outer space of the earth, it continues to spread, gradually covering the entire earth.

Looking from a distance, the entire earth is like a blue planet surrounded by a huge bubble. The bubbles that surround the earth are very thin, very silky, and there is a continuous stream of light flashing from there.

"Not bad. Although the defense level of this energy defense system is not very high because the life planet is too large, it is impossible to break this level of defense without a level 4 energy attack. If this energy defense technology is improved in the future, , But also defend against more powerful attacks. "

Qin Yi looked at the scene in front of him and smiled with satisfaction.

After that, you can sleep more securely. The defense problem of this life planet has always been a big problem, especially with the development of technology and the development of Xinghan civilization. More and more powerful ~ lightnovelpub.net ~ This life planet definitely cannot rely on traditional defense technology. It must keep up with the development of the times and have a more powerful defense system, so that you don't have to worry about being attacked by others.

"Oh ~"

It seems to be to verify Qin Yi's idea. In the void, an energy attack from a spaceship fell directly onto the light curtain in outer space.

This powerful attack of energy was like a large rock that fell into the lake water, which immediately stirred up a millennial wave, causing the light curtain of outer space to ripple.

But soon, these ripples slowly disappeared, everything was back to normal, as if nothing had happened, and the energy defense system perfectly resisted this energy attack.

Testing of the energy defense system was very successful.

Soon, this layer of light curtain began to slowly retract, and then the connecting rays between the basic point lines also disappeared quickly. This energy defense system is very energy consuming and cannot be turned on all day, only when necessary. Will open.
