[Transmigration] [System-Based] [Multiple Heroines]
Xu Yang spent eighty years accomplishing nothing in the cultivation world after his Transmigration. While picking out his own burial plot, he ran into a sect's Holy Maiden who had gone into qi deviation. After a passionate encounter, a notification rang out: [Ding! The Primordial Yin-Yang System has been bound.] He could use the experience gained from the union of yin and yang to improve his cultivation techniques and skills, as well as their mastery.
From then on, the Holy Maiden, the beautiful master, the lively junior niece, the stunning shopkeeper, the demonic sect enchantress, and all the rest were his for the taking!
"Fairy, want to improve your cultivation? Old Xu's got you covered."
