Lee Joohyuk, and undercover detective, has spent 15 years infiltrating the corporate-style gang ‘DG Group’. He was planning on revealing the evildoings of the DG Group to everyone in the world, toppling them… “Have a nice trip.” His identity was uncovered, and he was kicked out of the organisation. Just as the life faded from his eyes, an apparition of his father, a former hero, appeared. “Son, return here only after achieving the dream you so desire.” Joohyuk was sent back to the year 2005. “This time! Certainly, I’ll bring you down with my own two hands!” In an era where scoundrels and scum run rampant, I will become a villain, in order to eliminate all evil.

The soul of the charming and imposing Murim Alliance Leader, Hu Gong, suddenly possesses the body of a darn young man’s body one day.
That young man’s name is Beom Hang. He’s the young master of the ‘Heavenly Grand Archive’, one of the three major archives of the jianghu, yet a sorry excuse of a person.
In order to determine why his soul has swapped bodies, Hu Gong begins to train Beom Hang’s body. When the possessed young master of the Heavenly Grand Archive’s movements are totally different from how they used to be, it starts to attract the attention of the jianghu…

“I’m finally free!” After fifteen years of locking myself on top of a mountain, I returned to the world in order to compensate for the youth I had wasted during those past years. As I descended from the mountain, I made a resolve to pay all of my master’s grace by completing the Ten Virtuous Deeds as soon as possible and then live the rest of my life in leisure. With a sense of pride, I took the first step forward, but somehow things didn’t go as expected and the situation became increasingly complicated… Join him now on his journey to become the strongest in the world, in a place filled with betrayal and tears rather than justice and laughter, on the rivers and lakes!
