The War of Deification not only provided the Heavenly Court with enough manpower, but more importantly, it elevated the Jade Emperor from the ruler of the Heaven to the ruler of the Three Realms.
The original ruler of the Human Realm, the Human Emperor, also became the Son of Heaven. Therefore, Jiang Liu understood clearly that if he truly wanted to fulfill the mission of reinstating the Human Emperor, he would inevitably face strong suppression from the Heavenly Court.
However, if chaos were to occur within the Heavenly Court itself, leaving it no time to attend to the matter of reinstating the Human Emperor, it would naturally become much smoother.
For Jiang Liu, creating chaos in the Heavenly Court not only paved the way for reinstating the Human Emperor but also greatly reduced the pressure he would face during the final battle.
