Immortality? Might as Well Be the Villain!

I wholeheartedly hope to live in a cave, become an immortal, and live forever. Unfortunately, people are in the arena and can't help themselves. The entire fairy sect is full of villains. My teammates are all undercover! These guys, without me, they would always get beaten! The old guys are surrounding me... The villains all want to befriend me... Beautiful girl... Wanted my life in the end... The road to eternal life is long, so let's be a complete villain first! Where to start? Of course: teammates offer sacrifices to the sky, and their magic power is boundless! Only this time, what these old men are sacrificing is me!
