Kang Xu led a force of his soldiers into the imperial palace in an effort to abdicate the throne from Shu Liang. At first it seemed successful, but he was forced to face his longtime friend, Wuzhou. After a tense standoff the two friends dueled one another atop the Golden Bridge; Wuzhou was forced to kill friend by impaling him through the heart. Unfortunately, Shu Liang was killed when he risked himself to save Wuzhou. Many Tochii warriors had been slain the conflict.

Wuzhou had been offered to take Shu Liang's place until Shu Tian came of age, but Wuzhou denied the offer and decided to exile himself to Tochi as he felt guilty, once more becoming the Mizumi Master. He is now known as Master Wu and has been training the students there to become Mizumi Samurai. Some of these samurai end up becoming part of the Imperial Tigers.
