For instance, the turmoil in the Netherworld's kingdom of Hell, which has severed its ties with the Upper World, and the Netherworld's desire to use the power of the Netherworld Commander to intervene in the Yang World and disturb the balance of yin and yang in this world.
The turmoil in the Netherworld and its disconnection from the Upper World reminded Shen Yuan of the drastic changes he had speculated about occurring in the Heavenly Court.
Even if the Primal Chaos Realm were to sever its connection with the Heavenly Court, it wouldn't cause too much impact, for the Primal Chaos Realm is but one of many realms.
However, the Netherworld is involved in the cycle of life and death of all realms; the Heavenly Court must firmly hold the Netherworld in its grasp to command the heavens.
If it were not for a major upheaval in the Heavenly Court, the Upper World would never sever ties with the Netherworld or give up its control over it.
