Koun Ryusui

Commissioned by Qin Shi Huang, the court alchemist Xu Fu embarks on a perilous maritime expedition to the mythical land of Penglai. His singular mandate is to discover the elixir of immortality for his emperor. However, upon reaching the distant eastern shores, he encounters something entirely unexpected: an untouched paradise defined by lush, bountiful nature and inhabited by a sparse population of peaceful, primitive people. Captivated by the island's serene beauty, Xu Fu finds himself deeply enamored with this tranquil world, far removed from the rigid demands of the Qin Empire. This profound discovery forces him into a difficult dilemma. As he grows closer to uncovering the true secret of eternal life, he must confront the heavy moral cost such power demands. Will he fulfill his imperial duty, or will his devotion to this newfound sanctuary alter his destiny forever? Spanning millennia, this sweeping historical epic explores the enduring consequences of ambition and immortality across two distinct eras. The narrative is divided into two parts—the first chronicling "Xu Fu" and the second following "Nobunaga." It is a masterful work crafted by the acclaimed creator behind Otoko Ippiki Gaki Daisho and Salaryman Kintaro.
