The Shang's power continued to grow. In the 26th year of Jie's reign, Shang conquered Wen. Two years later, Shang was attacked by Kunwu, and several years of war between Shang and Kunwu followed. Despite this setback, Shang continued to expand on a number of fronts, gathering vassal troops in Jingbo. The Shang army and allied forces conquered Mitxu (today's 密縣), Wei, and attacked Gu, which too was conquered the following year. About this time Zhong Gu, chief historian of Jie, would flee from the Xia to the Shang.
