|“||The Emperor is still alive? Where? Relaxing while his people die for the Dynasty? The war will end soon and I'll become Emperor. Because I spill blood on the battlefield for the Dynasty's freedom. Not your father. And not you...||”|
|– Deng Rao claiming his right to the throne.|
Deng Rao initiates an attack to the Legion by attacking the Bamboo Fort. After he is punished by the player, Sarge warns him that they will kill ten Dynastians for each fallen Legionary and Deng Rao must deliver this message to their Emperor. Later, it is revealed that the invasion was Deng Rao's plan all along; the Dynasty never had the same intention at all.
Deng Rao reappears along with the Ambassador to meet with the leader of the Insusceptibles. He brought an assassin from the Order of the Damned which shocked June as it was dismissed by her father. He also badmouths June and the Emperor after his assassin is defeated, hoping to be the new emperor. Once the leader of Insusceptibles shows himself, however, he has no choice but to leave.
Deng Rao initiates yet another invasion to the Legion Fortress, this time using the help of the Dynastian prisoners and the Legion soldiers who have been bribed, in addition to his own army. Thankfully, Sarge knows and plans to stop this. With the help from the player, Marcus, and Itu, they thwart the invasion. Sarge then captures him and throws him in the prison, hoping that this will teach him a lesson to reconsider his dreams.
Sometime after the player entered the time portal with Shadow Mind, Shadow takes over the Legion and destroys both the Dynasty capital and the Heralds Dome. What happened to Deng Rao remains unknown.
