Fang Xi actually didn't intend to completely fall out with The Nine States.
Even though he had obtained a Primordial Spirit divine weapon, there were bound to be backdoors, and the highest permissions might well still be in the hands of Fang Immortal Taoist Palace!
'But I only need the second-highest permissions...'
'As if you have the guts to compete with me for control in the Southern Wilderness...'
'I only want this set of Primordial Spirit divine weapons entirely to protect the peace of the Southern Wilderness and to prevent the countless human race from suffering at the hands of the Monster Clan...'
After all, a Transcendent God of the Monster Clan might descend at any moment, and even fleeing to the Western Desert might not guarantee safety.
In the Five Elements Qilin Tribe of the Western Desert, there are bound to be Transcendent Demon Lords too!
Without a powerful weapon at hand, Fang Xi wouldn't be able to sleep peacefully.
