One wanted to punish the heavens for being cursed. One wanted to open the doors of hell. One wanted to find their purpose in life. Unfortunately for all of them, they were out of luck since they lacked the one thing needed to enter the greatest sect in the realm. Fortunately for all of them, they ran into someone willing to teach them almost immediately after being rejected from said sect. It's really too bad... that that someone just so happened to be a "mortal" mad scientist.  -o0o- Disclaimer, this is a multi-protagonist novel, so if you don't like that, this probably isn't for you.
