What is the soundtrack playing when Luffy beats 50 thousand enemies with Conqueror's Haki on Fishman Island?


I am just looking for the soundtrack that was being played when Luffy defeats
50 thousand enemies with Conqueror's Haki on Fishman Island in episode 554.




I think you're looking for [Sai, sai,
