In 3125 A.D., human society did not develop the exciting and brilliant technology as imagined, but fell into a completely unexpected barren and backward state. On April 1 of that year, a giant solar storm erupted, and ten minutes later, high-energy particles carrying huge energy descended on the earth, destroying the already shattered world in an instant.

Three million years later, the Earth was ruled by a new race, Dalota, which existed in the form of a soft body and survived by electromagnetic energy, which also created an extremely brilliant civilization, and in 9983 Dalota calendar, a sudden outbreak of a super virus caused the planet to disappear again.

Another 5 million years later, perhaps the most intelligent life form ever existed on Earth, the Capechkals, appeared, and it took them less than 1,000 years to raise Earth's civilization to unprecedented levels. When they were ready to march into the depths of the universe, no one expected that the second leader would suddenly launch a coup d'état. Bombarded with powerful super-technological weapons, this civil war wiped out the face of the earth in just one month for a great civilization with infinite hope for the future.

In this way, 120 million years passed slowly, and the vicissitudes of this small planet were only a flick of a finger for the vast universe, and various civilizations appeared several times but were ended for various reasons, and desolation and coldness once again shrouded this land, and this situation lasted for 8 million years.

Finally, the flame of civilization was ignited again, and new life was born on the earth, and after a miraculous evolutionary process, this new, but familiar species finally became the master of the earth.

There is a country called the Song Kingdom, and Haijing City is the largest and most prosperous coastal city in the Song Kingdom, and the beginning of this story takes place in Haijing University, which is located in the southwest of Haijing City.
