The Disqualified One of the Abyss of the Heart

[The Forbidden Zone's endless darkness is just a child's innocent and adorable fantasy] Fifty years ago, a sudden [Emotional Storm] changed the world forever. As humanity's only hope against the disaster, [Purifiers] risk their lives to fight for the survival of humankind. A prodigious young genius appeared out of nowhere, changing the despairing reality of the [Forbidden Zone] steadily encroaching on the world. But ask those who know him... "Su Jixi? Don't mention him to me." The man who had once been a hero, only to fall from grace, let his gaze flicker. "Heh, I'd be glad if he were dead!" The black-haired young man, doggedly searching for the truth and his past, gritted his teeth. "Meeting him was the worst luck of my life!" The girl who had faced the cruel truth clenched her fists in anger. Everyone says, "That idiot has no idea what he's doing!" But when the Forbidden Zone erupts, contamination spreads, and the world is once more plunged into crisis... Everyone hopes that the purple-haired boy will return from the darkness once again. A reading guide: There are already plenty of gentle types, so let's have some fun with a possibly mischievous male lead. There will be lots of detailed worldbuilding, just so you know. Whether he's the arrogant, show-off type is a matter of opinion (looks away). From Jixi's perspective, he may seem like a show-off, but the story leans toward an ensemble cast. No CP, no CP, no CP. Our protagonist will say things like "friendship" and "bonds," then scoff and charge in by himself (?). That's all. Interested? Go go go! Theme: Never give up on hope that you can still grasp.
