However, in the hot and humid climate of the south, an epidemic broke out quickly amongst the soldiers, and the weakened army was unable to cross the mountains, forcing them to withdraw which ended in Nanyue victory, but the military conflict did not stop until the Empress died. Zhao Tuo then annexed the neighboring state of Minyue in the east as subject kingdom. The kingdom of Yelang and Tongshi (通什) also submitted to Nanyue rule.
