Civilization Fission: Unnamed Variables

At the end of known civilization, humanity's only answer is the Sixth Realm. Martial arts, magic, and physical fitness—the three extraordinary paths have each developed for thousands of years, but they are always restricted by the same invisible ceiling. No one knows what it means to take another step forward, and no one truly believes that that step still belongs to mankind. Until that day. A time travel that shouldn't have happened threw five ordinary graduates who originally belonged to modern civilization into a world of high-level martial arts that far exceeded imagination. They were forced to separate and landed on an isolated continent, but they maintained an unbreakable connection deep in their consciousness. They are not the Chosen Ones, nor the prophesied heroes. They are simply recognized by the world - variables. When the rules begin to fail, when the existing system cannot explain new phenomena, when the king of the sea wakes up and the king of land overlooks human civilization, five insignificant individuals are deviating from the originally destined trajectory of the world in different ways. No one knows whether fission will lead to evolution or destruction. The only thing that can be confirmed is—— From the moment they appeared, the future of civilization was no longer a certain answer.
