Arknights CC#1 (CC3) Pyrite Canyon Risk 27 (Guards and Casters Banned)

I've done it by referring to my two risk26 videos that I uploaded before.
The final boss in Pyrite Canyon is Breaker. They irritated me the most until appearing Phantom Leaders in middle phase. But in the end, I did it.
I muted in game bgm to prevent mental illness. and overlapped ncs bgm.
