Legend has it that when the former king became the Son of the Moon Festival, he acquired a mystical ability: through touching with his palm, he could impose the Moon Lake's Judgement on any native creature within Jie Lin. If the judged creature had committed grave sins, it would immediately die on the spot.
However, this ability was rarely used by the former king, and over time it became merely a legend. Today's young people have only heard of the name, without understanding the specific judging process.
Only the elderly tribesmen know that the so-called 'Moon's Judgement' essentially involves releasing the Moon Butterfly from the target creature's body, causing them to die prematurely.
Throughout history, this ability was possessed only by the former king.
And now, this outsider emerging from Moon Lake has perfectly replicated the former king's ability.
If he's not the Son of the Moon Festival, then what is?
