Boss, Spare Me a Little Immortal Aura!

Our boss, Ma Fufeng, was the first person in all the realms to become a true immortal. He was always going on about how powerful he'd been, calling himself “the number one immortal since time immemorial across all the realms.” He could crush mountains and overturn seas with a wave of his hand, destroy the heavens and the earth. Unfortunately, I, Ye Cheng, wasn't impressed, because I had a System. Sure, this System was pretty useless. It was always turning the world into a complete mess, and most of the time it hurt the enemy by a thousand while costing us eight hundred. But no worries. Ma Fufeng would step in and smack them to death... Hey, hey, Boss, now that we're rich, we still have to spend wisely. At least share some immortal energy with me!
