玄菟郡
Meanwhile, the two 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.
