I transmigrated to the world of Doupo (Battle Through the Heavens). I became a "useless" member of the Mittel family, plagued by a cold poison, spending my days with alcohol and enduring endless scorn. But I had a little secret: the drunker I was, the faster my sword became. My family didn't understand; they only saw me as a useless person who couldn't live without alcohol. Even my cunning cousin, Mittel Yafei, saw me as an obstacle to her claim to the family headship. A frame-up made me a sinner of the family, and I was expelled. That day, I lay drunk in the dilapidated courtyard, dreaming of immortals dancing with swords. When I awoke, I realized I had been bound to the [Drunken Sword Immortal] system. I soared to immortality with a single sword strike, leaving this family, reeking only of money, alone. From then on, the Douqi Continent gained a drunkard.
