Background:
July 11, 2115
73% of cities around the world have been hit by doomsday storms.
Only 3% of the safe zone remains, and 24% is being hit by the doomsday storm.
Qin Kuai (fourteen years old) who was in the safe area was watching the news when suddenly a meteorite crashed into his house.
After being touched by him, the meteorite broke into five pieces, one of which merged into his body.
On August 11, a teenager found him and told him the origin of the meteorite.
Qin Kuai and others are the "elemental stars" selected by the "Heart of Solid Realm".
