After Tongtian Jiaozhu set out the Ten Thousand Immortals Formation he raised the Six-Soul Banner behind it, with the names of Taiqing, Yuanshi, Jieyin, Zhunti, Jiang Ziya and King Wu written along its tail.
He ordered Changer Dingguang Xian to guard the banner and to shake it without stopping when the decisive battle came. Instead Dingguang Xian carried it over to the reed pavilion; the Six-Soul Banner was never set going inside the array, and the Ten Thousand Immortals Formation was broken afterwards.
Yuanshi and the others looked at the names on the banner and did not use it, and Jieyin took Dingguang Xian west. Having lost his last resort, Tongtian had to go before the lines and go on fighting himself.
