The square at dusk is very busy, crowded and noisy.

The square is surrounded by tall broad-leaved trees. When the evening breeze blows, the fragrance of leaves wafts everywhere, making people feel more refreshed.

As night gradually descends, the square presents another scene.

Neon lights flash, flowing lights overflow, and the stars and the moonlight shines together, making them charming.

"Ding dong, ding dong."

The melodious and ancient bell rang, and the bustling crowd began to surround the giant stage in the center of the square.

Accompanied by the warm background music, ten thousand young children were standing on the stage in an orderly manner.

After a while, the loud chanting began to float around

"The earth is sacred and beautiful. It is the mother of mankind, the cradle of life, and our home. The sky is blue, and you can clearly see white clouds. The green mountains and clear waters on the ground are bright. The gentle breeze, the continuous drizzle, the blue ocean, the bright moonlight, the fresh air, the clear river, the mysterious forest, the precious plants, the cute animals. How beautiful and precious all of this is! The sun and the moon are good friends of the earth... The earth is always our home!"

Children's minds are simple and clear. Because they are ignorant of the world, they always treat everything genuinely.

The mind is a magical place. For adults, as time goes by, the world of childlike innocence has long become blurred and distant.

Perhaps, children do not understand why adults are anxious every day. Although they have heard about the end of the world from adults, this cold word seems very flat and thin in their minds.

Today is the grand ceremony for the completion of the first [Geocentric city] on the earth!

Media from all over the world are broadcasting this historic moment to people in every corner of the earth.

When the children's chanting ended, a middle-aged man in his forties stepped onto the stage with steady steps and stood in front of the podium on the right.

The middle-aged man's eyes quickly passed by the crowd below the audience, and a passionate voice rang out.

"Dear ladies and gentlemen, and dear children, good evening!"

"I am very honored that I have become the first mayor of Rainbow City, the first underground city in human history. First of all, I would like to thank the adorable children for their wonderful chanting. Your voice is like your heart at a glance!"

When the middle-aged man said this, he bowed deeply to the audience.

"Although people living in underground cities will temporarily lose the bright sky and colorful world. However, this cannot erase our yearning for a colorful world. This is also the meaning of the name of Rainbow City. At the same time, I also want to take this opportunity to proudly tell the whole world that in the artificial sky of Rainbow City, residents can really appreciate the bright colors, looming and colorful rainbows."

"From the next month, the first batch of residents will be the first to enter the [Geocentric city]. We will live, study, work in the Rainbow City, and undertake the important task of inheriting human civilization until we finally overcome the crisis. We are lucky, and we should be grateful."

The completion of Rainbow City is of great symbolic significance to the construction of [earth-center city] around the world. In addition, Rainbow City will also shoulder the important task of an underground city experimental model.

In the design plan of [Geocentric City], because it is uncertain when the gamma ray burst will arrive. Therefore, before the crisis breaks out, every [Geocentric City] will make full use of the hematopoietic ability of the surrounding surface areas and continuously create sufficient energy, food and other consumables for itself as reserves.

However, considering that after the crisis broke out, [Geocentric City] must have the ability to be self-sufficient. Therefore, Rainbow City took on the heavy responsibility of the Experimental City.

In short, after completing the construction and obtaining sufficient resource supply, Rainbow City will no longer accept external material assistance, and use this to test the city's ability to survive independently in the underground world.

The energy and minerals of Rainbow City can only be mined from deeper underground areas, and food must also be produced by artificial sunlight systems. In short, Rainbow City will enter the fully enclosed ecosystem operation stage in advance, and the animals, plants, and microorganisms inside will be evaluated and screened more strictly.

As a pioneer of [Geocentric City], Rainbow City will provide valuable experience for the construction and operation of other underground cities.

Of course, during this period, the exchange of relatives and friends between underground cities and the ground world is still allowed. However, the entire underground city will strictly abide by the strict population management principles. To put it directly, it is: only going out but not entering!!

Residents of underground cities can apply to visit relatives and friends living in ground cities, but people in ground cities are not allowed to enter [Geocentric cities] (except for temporary work by special scientific researchers and government heads. Moreover, they must withdraw in time after the work is over!)

Just as construction was underway around the world, some discordant notes appeared again inappropriately.

"boom!"

A row of human walls connected by police officers was finally pulled out by the surging crowd.

Before the police officers could form a new line of defense, countless manic and uneasy people broke through this opening and quickly defeated the entire wall.

The crowd was very angry, and countless heads were surging one after another, surrounding the municipal government building at an extremely fast speed!

"Stop creating space city!"

"Bank the construction plan for electromagnetic catapult tracks and space elevators!"

"The waste of resources is prohibited, we need more [geological cities]!!"

Scream! Swear! Scream!

A noisy whirlwind gathered among the crowd, as if to overwhelm and devour everything.

The whole scene was approaching the brink of collapse, and everyone waved their arms and ignited each other's anger with cynical and intense words.

"Play!!"

With a crisp tearing sound, I don’t know who took the lead in smashing the huge stones on the glass curtain wall of the building.

The crowd was quiet for three seconds at first, and then a sudden change occurred. Everyone lost their last trace of rationality, and the scene became uncontrollable!

Under incitement, more and more people began to rush into the city government building and smash everything that their eyes touched.

"Woo! Woo! Woo!"

At this most critical moment, a harsh alarm sounded, and a large number of troops finally arrived!
Chapter completed!
