In the past, Wu Jinhai really liked to cause trouble with anyone he knew. It wasn't just demons who were his targets, even fellow humans who lived in Wu Li couldn't escape his wrath several years ago.
At that time, there was a festival in the Xinyang Imperial Palace, and many people celebrated around the palace. In front of many people, Song Tingfeng suddenly challenged Wu Jinhai to remove the golden mask that had covered his face since he was young. Back then, Wu Jinhai still had golden scales on his forehead which were nothing but proof that he was a half-fish demon, and there was no way he would accept the challenge.
Wu Jinhai refused the challenge, choosing to accept the shame if others saw him as a coward because he was unwilling to remove the object that had been covering his face. He thought everything would end in such embarrassment for him, but he was wrong because Song Tingfeng suddenly charged towards him, trying to remove his mask by force.
