Our Mother Earth gave birth to so many creatures, but it didn't occur that it was humans who would destroy themselves; The whole earth is deserted, and all the buildings have collapsed.

Originally as the most beautiful planet in the universe; The beautiful blue planet that would be fascinated by anyone who looks at it now looks like no other planet, and that beautiful planet is gone forever.

This is the year 782 of the Fallen, that is, in 2852 AD, because of the environment, all humans have to rebuild their homes underground, this is an underground city made of all the minerals on the earth, or more like an underground prison in which humans are trapped.

Less than 100 million of the world's 13 billion people were left because of the catastrophe: by 2070, all the earth's energy has been depleted, carbon dioxide has covered every city in the world, glaciers have melted, sea levels have risen and all coastal cities have been submerged, and "three parts of land and seven parts of the ocean" have finally become "one part of land and nine parts of the ocean".

In the end, it was human greed that ruined itself, the marine pollution creatures mutated, and there were few creatures left on land except humans, only the creatures in the ocean survived, not only simply living, but also mutated into monsters.

However, twenty years before the Fall, people had already been aware of this, and began to move the world's minerals, no one, whether rich or the ruler of the country, was not allowed to take any minerals, all the minerals were building the last hope of mankind, and this known as the largest building in human history was born - Farr. It covers an area of 20,000 square kilometers, two kilometers underground, and such a difficult project was barely completed in 20 years, as well as an artificial sun.

That night, all the radio stations on the planet were broadcasting, as long as healthy humans under the age of eighteen and young people between the ages of twenty and thirty without a history of disease! And, of course, hundreds of scientists with cutting-edge technology.

Some people cried all day, some people stuffed gifts and money, these people were driven away directly before they met the requirements, and some troublemakers were shot directly, at special moments, I really didn't joke with you.

There is a huge elevator on the ground that can carry thousands of people at a time, and it takes nearly two days just to transport eligible humans to the interior of Farr.

Eligible humans have entered the Farr, but not all, only 50 million humans have entered it, and all the humans inside are just like the original earth, but the green color is missing; Schools, companies, residential areas, etc., it is like a big city.

In less than a month, there were very few people left on the ground, and even if there were survivors, even food was a problem, but Farri's food was quite sufficient, and it was also moved into the world's largest gene seed bank, and it took scientists a year to recreate most of the useful plants and animals.
