Celestial Martial Continent, where powerful individuals gather like clouds, and sects are found everywhere.The anger of a strong individual can burn the heavens and boil the seas, overturn the skies with a wave of their hand, and change the sun and moon with a flick of their finger.Huaxia Martial Arts Grandmaster Chu Ming, equipped with the Sword God System, unexpectedly arrives in this world. He becomes an outer disciple of the Cyan Yang Sect, possessing extraordinary comprehension, photographic memory, and the ability to traverse the Violet Micro universe, dominate starry rivers, and conquer the myriad realms across heavens.

When an S-class elite assassin-raised captain of a special ops suicide squad comes home from a high-stakes Africa mission, he finds himself offered something that could potentially set him up for life- a curious assignment that he could use to finally exit his days of war and slaughter.

Then placed into a high-school setting, Lin Yi is tasked by the chairman of a top-tier multi-billion company with bodyguard duty for non-other than his own daughter, a certain little Miss of said high-school.

His enemies, once ranging from drug lords, mafia bosses, political figures, and national leaders, are soon replaced with spoiled kids who happen to have rich papas and mamas, and Lin Yi finds his intense expertise and high-threat skillset misused, and very underwhelmed…

But he does get a harem cast as diverse as his old enemies, so Lin Yi decides that, for the sake of messing around with girls as an invincible entity in a down-leveled environment, leaving his bloody and death-filled war days behind is something he’d definitely want to strive for.

Precisely then, the bottom once again went back to his timeline — back to when he and the top were just platonic childhood friends.
