A modern-day antihero, who was infamous for his devious acts, dies in an explosion meant to take down a powerful criminal syndicate. Waking up in a world of sword and sorcery, he finds himself possessing a fragile, powerless body with a strange “System” that seems broken. Initially thinking he's doomed, he learns that by pretending to be weak, he can manipulate others into revealing their secrets, granting him abilities they possess. As he rises in power, he discovers that the System was intentionally sabotaged—by none other than his own future self.

In the vast and boundless continent Cangtu, there were ancient sects governing the Ten Old Domains, unworldly immortal clans beyond the Blue Sky, and primordial demon gods dominating the dark abyss that together created a great number of brilliant stories over the long course of the history.

In this very world, there was a boy, named Lin Xun, who embarked on his journey to the pinnacle of strength alone through cultivation and spiritual tattoo inscribing.

Escaping alone from the Mine Prison where he had been living since he was adopted by Master Lu, Lin Xun knew nothing about his identity but the little information his adopter, Master Lu, had told him. With two ancient spiritual tools Master Lu gave to him before the destruction of the Mine Prison, Lin Xun started his journey to Ziyao Empire, where he is supposed to find out the truth of his lost Spiritual Vessel and the person who slaughtered his family, leaving him orphaned.

Will he be able to unlock the mysteries of the two magic treasures, unveil the secrets of his identity and create a legend of his own?
