After ruling Goguryeo for fifteen years, Jumong succeeds in reuniting with Yesoya and Yuri (who had been living in exile after escaping from the palace). Following Geumwa's assassination by Han mercenaries, the newly-crowned King Daeso forms an alliance with Jumong, and the combined armies of Goguryeo and Buyeo succeed in conquering Liaodong Commandery with utter annihilation of the Han army in Manchuria. With Jumong's lifelong mission finally complete and in order to prevent internal strife due to Yuri's return, Soseono departs from Goguryeo and heads south with the pro-Jolbon faction and her teenage sons Biryu and Onjo, who subsequently found the Kingdom of Baekje on the Korean Peninsula. Buyeo eventually collapses following the battlefield death of Daeso at the hands of Jumong's grandson Muhyul. Jumong continues battling against Han China to consolidate his realm, and dies at age 40 after passing the crown of Goguryeo to Yuri.
