General Oi

General Oi (오이, 烏伊, ?-?) was a general who helped founding the Goguryeo, one of the Three kingdoms of Korea.

Biography
Oi, Hyeopbo, Mari, and Jumong were associated as friends. Jumong made them his bodyguards during the time he was at the palace and Oi's career started from this point.

Meanwhile, the 2 sons of King Geumwa became jealous of Jumong's archery skills and Jumong was forced to leave Dongbuyeo along with his bodyguards. In 37 BC, Jumong became the first king of Goguryeo and reunited all of the five tribes of Jolbon into one kingdom. In 32 BC, Jumong sent General Oi and Bu Bunno (부분노, 扶芬奴) to conquer the Haengin state (행인국, 荇人國). Also, Jumong, along with Oi went to spy the Xuantu Commandery, and in order to escape, they killed approx. 500 soldiers.

In 14, he and Mari attack the Yangmaek state (양맥국, 梁貊國), and Gaogouli County in Chinese Xuantu Commandery during the reign of King Yuri, second ruler of Goguryeo, and eldest son of the King Dongmyeong (Jumong).
