The Mu Abode is the power that's lead by Mu Chen. It was created from the forces of the Northern Alliance. Though as a Greater Earth Sovereign, Mandala was supposed to lead such an alliance but she knew of Luo Li’s troubles so she made Mu Chen step forward as the leader because Mandala knew he couldn’t go to the Luo God Clan alone. Because at this time Mu Chen had just broken through to Earth Sovereign, no other Lesser Earthly Sovereign wanted to submit to him, so Liu Tiandao challenged him to a fight to prove his qualifications [1]. After Mu Chen sets up his improved version of the Nine Dragon God-Killing Array of which he can control 7 dragons, Lu Tiandao admits defeat and the other Lesser Earthly Sovereigns of the alliance submit as well. It’s only after Mu Chen kills one and severely injures two Lesser Earthly Sovereigns of the Blood God Clan by himself without even using Three Pures that all of them truly submit from the bottom of their hearts.[2]
After Mu Chen defeated all the five leaders of Greatlaw/Skylaw Alliance, Mu Abode became the sole ruler of the entire Skylaw Continent.[3]
