Taking on Disciples Brings Ten-Thousandfold Rewards, Yet I Live in Constant Anxiety

Multiple heroines: senior sisters, junior sisters, a master, and disciples.

There's a real plot, and the protagonist is nearly invincible. It's funny and passionate, with everything you're looking for.

The female disciple spends all day plotting how to kill her master, while the master is bound to a System that prevents his disciples from being harmed.

A battlefield between sisters, and another between master and disciple.

If it's not your thing, please don't flame it. Stick with it and trust me: if you make it through 25 chapters, you won't be disappointed.
