My Senior Sister Refused, but the Demon Emperor Master Gave Herself to Me?

"Wait, what? If I don't date someone, it'll get cut off!" Su Mu transmigrated and received one good piece of news and one bad one.

The good news: He transmigrated and awakened a System that could keep producing invincible rewards. The bad news: If he didn't fall in love within a month, his equipment would be confiscated on the spot. The good news: He had seven senior female disciples whose cultivation was supreme and whose beauty could topple kingdoms.

The desperate bad news was that his master had a rule: fellow disciples weren't allowed to date! No way! I have to go down the mountain! Otherwise... "But Master, why are you blushing?" And, senior sisters, didn't you all turn me down before? Why are you all clinging to me now? Princesses, fairies... please don't be like this!
