Since Gun was executed on Yushan, endless crimson snow fell for three days and nights, and Heaven and Earth mourned together.
The Human Clan believed that this was Heaven and Earth voicing their disapproval of Gun's treatment. Hence, many provinces consciously disobeyed Emperor Shun's orders in secret while obeying them in public.
Moreover, at this moment, the Human Clan could no longer find anyone capable of controlling the waters. Emperor Shun had no choice but to seek help from Jieyin again.
Sadly, Jieyin had been severely injured previously by the Hai Pig incarnation controlled by Li Qingming, and his Primordial Spirit was greatly damaged. After returning from the Western regions, he simply secluded himself in Leiyin Temple, which was constructed in the capital, and entered a closed meditation.
Thus, Emperor Shun was bound to return disappointed.
With no other options, Emperor Shun had to personally take up arms and deal with the water control.
