Su Yu, the Prince of Zhennan of Great Xia, lived a peerless and carefree life in his first incarnation, yet, lacking a spiritual root, he was denied the path to immortality and passed away with a smile. After death, he bound himself to the Book of a Hundred Reincarnations Against Fate. As long as his bloodline survives, he can reincarnate endlessly, earning Fate-Reversal Points from each life's evaluation and freely allocating them to aptitude, fortune, and family background. In his second life, he reincarnates at the bottom of the cultivation world with a ninth-grade inferior spiritual root. He patiently lies low and survives the catastrophe that wipes out his family, building the Hidden Dragon Su Clan from the ground up. Yet his poor constitution ultimately limits him to the ninth level of Qi Refining. When his lifespan runs out, he reincarnates once more, carrying the accumulated experience of a hundred lifetimes, and continues his endless cycle of rebirth as he ventures into the vast world of immortal cultivation.
