Arnold never thought his gaming skills would land him in a romance novel—as a doomed side character, no less. To survive, he hijacks the heroine's “system,” bending the story to his will. But when he dodges a deadly duel, he catches the eye of the heroine, Lara, his own step sister—and her love is a dangerous game. Arnold must outwit the plot and his step sister who's not afraid to kill for love. In this LitRPG romance gone wrong, survival isn't just about beating the system—it's about escaping the heart of a yandere.

She was a peerless genius in the 24th Century – all she needed was a silver needle and she could practically bring anyone back from the dead.

What kind of experience is it to be a true spiritual genius, transmigrating to become the ‘king’ of the Immortal Demon Great Qin?

Qualification is supreme, and any technique can be mastered quickly. The so-called barrier of practice cannot hinder his breakthrough at all!

Or add luck and become the real master of the plane.

Is it to gather the copper of Kyushu, cast twelve bronze figures, hold the souls of millions of Qin warriors, swept across Liuhe, and conquered the world, or the three worlds of warriors?

Rare birds and beasts, a world where demons are rampant, a combination of local myths and legends.

PS: It is not a hegemony text of the war system, the first choice for the extreme genius stream
