Getting Stronger Starts with Going AFK

[Friendly warning: This is a familiar old-school story. Don't read if that's not your thing.]

Liu Xuan transmigrates into a river. After being rescued, he gains an AFK System!

No matter how difficult a technique or cultivation method is, as long as Liu Xuan gets his hands on it, he can master it by training AFK.

If you can cultivate lying down, why stand up?

If you can train AFK with ease, why practice day and night?

All I want is to master divine arts without breaking a sweat. The hard work of diligent cultivation has nothing to do with me!
