The male student, Fukai Nagamasa, ignores his studies for college entrance exams in favor of following the path to chuunibyou. As he fainted during night cramming session before the exams, he realized that he was transported to a parallel world as a feudal lord in the Sengoku Era. Not to mention that suddenly, he was marrying the sixth Demon King, Oda Nobunaga’s little sister, the one who was purported to be an unrivaled beauty?

In the world of cultivation, countless tales follow righteous protagonists, fated heroes blessed by destiny, or those chosen by heaven to walk the path of immortality.But what of those who stand in their way?What of the villains? The so-called obstacles to the hero’s journey—do they not bleed, dream, and struggle as well?Xiao Ning was never meant to succeed.From the very beginning, the Grand Dao wove him as a stepping stone—a necessary sacrifice to elevate another. His path, like that of all designated ‘villains,’ was doomed to failure by design.But what happens when that design is defied?After death, Xiao Ning awakens—not in the cycle of reincarnation, but in the cold silence beyond it. There, he is offered the Eternal Paradox Codex—a forbidden artifact containing the hidden truths of the Grand Dao System itself.Rules. Loopholes. Vulnerabilities.Knowledge not meant for those like him.With this power, Xiao Ning is granted a single, impossible choice: accept oblivion, or step outside the Grand Dao entirely—to abandon fate, sever karma, and cultivate a path unbound by heaven or law.It is Xiao Ning’s journey, from ashes to something beyond comprehension.Not to become an Immortal among men.But something even the heavens dare not bind.If fate is a chain…Then let him forge his own path in the void beyond.Welcome to this humble tale.The cultivation world is vast and unkind.Let us begin again—on our terms.

A scientific genius named Thomas Harrier was transmigrated to an imperial prince body after a car accident that took his life. He found out that he is in a world similar to our own with a timeline akin to early twentieth century. The body that he is occupying was the imperial prince of a failing empire who suddenly rose to power after a successful assassination attempt of his father. Unaware that the attack is just the beginning of what is to come. He faces many challenges throughout.
