Quick Transmigration: I'm Here to Save You, Villain

Qi Zhuxue, the ancestor of the Xunxian Sect, had been called a genius since childhood, but she had one very, very big problem: she wanted to grow taller. One day, a System came to her and said that if she completed missions in other small worlds, she could grow taller. Little Ancestor Qi Zhuxue: Her smile slowly spirals out of control! Hehehe (º﹃º). System: Why do I suddenly feel a chill? Little Ancestor Qi Zhuxue: What are you waiting for? Get moving!! And so, for the first time, the System was forced to go on a mission! System: ???? This is the first time I've met a Host this eager! I feel like I'm completely useless now _(:з"∠)_
