In his previous life, Happy had entered Sky Demon Secret Cave multiple times, and he knew everything in it very well.
The resources in Sky Demon Secret Cave was something that he knew the clearest, but aside from them, the thing that left the greatest impression on him was Lightning Executioner Xing Wuzui's strength. He was an elite at the peak of Inaction Realm in charge of Sky Demon Sect's punishment hall, and he was only one step away from Myth Realm. He also happened to be one of the vice sect masters of Sky Demon Sect.
As a vice sect master of Sky Demon Sect, he had the strength to protect Sky Demon Sect and make all those who wanted to invade it stop in their tracks.
However, Happy knew that he had a fatal weakness.
All evil cult elders chose to sound the golden bell when they were at a disadvantage while fighting against the invaders and called for reinforcements. Only Xing Quzui would never sound the golden bell!
