Xuan Tian truly could not comprehend the actions of Xuan Qingyun, but regardless of what Xuan Qingyun was doing, Xuan Qingyun and his position were always opposed, so Xuan Tian would remain vigilant against her.
Xuan Tian felt that continuing like this was not a solution; he must swiftly destroy the Immortal Artifact in Lu Chen's hands.
The best way now was to leverage the power of the Divine Martial Emperor. He could first help the Divine Martial Emperor become stronger, and then attempt to use the Divine Martial Emperor against Lu Chen.
Although this universe was the world within Xuan Tian's body, he himself could not completely control what happened inside. Take the Immortal Artifact, for example; he could only find a way to expel it, unable to destroy it.
This was like a mortal having a stone in their body, where they can only use external force to break the stone, unable to rely on their own strength to expel it.
