Five years ago, Ethan Kane, heir to the Jiang family, was ambushed by the Venerable Hall and fell into the sea. He was rescued by Master Tidecaller, a reclusive expert, and spent five years in rigorous training on a deserted island, mastering peerless martial arts and medical skills. Upon his return, he reunites with his fiancee Luna Stuart, who has waited for him for years. He helps her fight against family power grabs, forced marriage from the Chandler Clan, and competition from the Five Lakes Conglomerate over the Linyuan Port project, while investigating the truth behind his parents' murder and the collapse of the Jiang family. Facing successive martial arts enemies and behind-the-scenes forces, Ethan sweeps through all opposition with his invincible cultivation, eventually killing the Hall Master of the Venerable Hall at the Martial Association arena to avenge his parents. With all conflicts resolved, he moves into a lakeside villa with Luna Stuart, fulfilling his promise to spend a lifetime together.
