Master Sun was naturally Sun Wukong. He had been paying close attention to the situation in Southern Shenzhou.
Having learned about the flood in Nanyang, after a brief investigation, he discovered it was caused by demonic disturbances.
Recalling the previous flood in Chang'an, he immediately surmised that this might be Buddha Sect's covert act to support the new dynasty of Wang Mang.
Since celestials were forbidden from intervening in the human dynastic successions, and it was the time when Liu Xiu was uprising against Mang, Buddha Sect dared not to take the risk by acting directly and thus instigated demons to create chaos.
This kind of incident had happened before, where the Buddha known as the Great Sun Buddha Lu Ya had once lead ancient demons and the Demon Cult together in an attempt to unlock the seal of the Northern Sea's Eye.
At this moment, hearing the Huai Water Dragon King blame Wu Zhiqi for the unrest, Wukong nearly confirmed his suspicions.
