The King of Soldiers Across Film and TV: I, Cheng Cai, Never Abandon or Give Up

[Crossover with film and TV + elite soldier + hard-core military + righting past wrongs] Cheng Cai, a super-soldier codenamed "Ghost," dies while trying to stop terrorists from destroying all of humanity. He dies with regrets: the world is on the verge of destruction, and he has fallen just before the dawn. When he opens his eyes again, he finds himself in a mysterious space. A mysterious cycle of scripts has the power to reverse time and space. Only by traveling through the worlds of these scripts, completing high-difficulty missions, and accumulating enough "Cycle Points" can he earn one chance to "reverse time and space": return to his original world and rewrite humanity's fate. But "they" arrived in the script worlds before Cheng Cai did.
