The Ruler of the Land(1994)

An intricate story revolving around Han Bi Kwang, as he follows a hero's journey. Just throw in a historic setting, ancient weapons, and a riveting plotline, and you have one of the most highly-acclaimed manwha, a definite must-read.

Bi-Kwang and Hwa-Rin try in vain to shake off Sang Pil "Gold Cobra" Jin and his men, but, ultimately, they are forced to defend themselves. Unfortunately, Bi-Kwang and Hwa-Rin lose, and the Sword of the Flowers is taken from them.

Bi-Kwang and Hwa-Rin regroup, pursuing Sang Pil Jin in an effort to retrieve the sword, but then Sang Pil and his men learn that Bi-Kwang and Hwa-Rin aren't the only ones after them. Sang Pil's superior, Master Yoo, has learned that Sang Pil planned to keep the sword for himself, and has approached Shi-Yun, leader of the Black Serpents, for help.

The lives of Bi-Kwang, Hwa-Rin, Sang Pil Jin, and his men are all in danger, as Master Yoo and the Black Serpents join forces and search for the sword together.
