Twenty years ago, nine powerful families destroyed Lin family to seize their Secret Vault, wiping all records of it from history. The sole survivor, Lysander, fell from a cliff and was taken in by a reclusive master. With heaven-defying talent, he reached the peak of the mortal realm in just twenty years, yet failed to ascend due to unresolved karma. Sent down the mountain, Lysander meets Theresa and uncovers a fate-bound connection tied to her family. Becoming a reluctant live-in son-in-law, he steps onto a path of destiny, revenge, and awakening.
