I Picked up the Destined Child and Became a Master of Cultivating Immortals.

[Loli+Sand Sculpture+System+Easy] My name is Ye Lin. When I woke up, my sister and I traveled to this world called Tianlan and became immortal cultivators. But my system Ajiu wants me to pick up the destiny child of this world before I come back to activate Ajiu. What I didn't expect was that my perverted lolita ex, Ji Ziying, would also come to this world, and she would be Ajiu's designated destiny child! And the story of our three girls also begins!
