Useless Sect Master gets a 100x rebate system,all spending gets 100x rewards to become the #1 master

Betrayed by my best student and left for dead, I thought my life was over. But then I unlocked a system that's basically a glitch in reality. The rule is simple: anything I give my loyal students, I get back 100 times over. A basic pill? I get a god-tier elixir. A common sword? I get a legendary divine blade. Watch as I turn my three underdog disciples into the most overpowered cultivators alive and build the ultimate sect from nothing, all while getting epic revenge on everyone who ever called me a loser.
