Genghis now moves to Ganzhou, the hometown of his general Chagaan.

Chagaan's father still commands the city garrison, so Chagaan attempts negotiations with him.

However, the second-in-command of the city stages a coup, kills Chagaan's father, and refuses to surrender.

The city takes five months to subdue, and though the now furious Genghis threatens vengeance, Chagaan convinces him to kill no more than the thirty-five conspirators who had killed Chagaan's father.
