Passing on a hundred times the cashback: being a teacher means having a lot of cultivation!

Qin Xuan traveled to the Xuanwu Continent and was bound to the [-]-fold cashback system for passing on skills.
As long as you give empowerment and pass on the skills to your disciples, you will get a hundred times the power back!
Years later, the disciples have become terrifying legends in the world of cultivating immortals one by one.
"Master, don't pass on your skills anymore, I'm going to become the Nine Heavens Immortal Venerable!"
"I caught two phoenixes and made them stew for you. Master, why don't you just rest for a day and not teach the exercises?"
"Master, I have captured the fairy princess you were talking about, so why don't you rest for a while?"
Qin Xuan sighed, the whole heaven trembled, and said helplessly.
"Hey, to be a teacher is to cultivate a little more, is it so difficult to pass it on to you?"
