Dress up as an NPC and Become a Big Sister While Eating Melons

Xia Rou, a social animal, traveled through time to study immortal literature and became an NPC in the book. She was also bound to a [getting ahead] system. She had no power at the beginning, so she squatted in the corner and ate the melon in a fancy way, and understood the direction of the original work, the secrets of the sect, and the ins and outs of all parties. I originally wanted to hug the protagonist's thigh and become famous, but instead I wanted to eat the melon and become Sister Rou. There was no other way. She decided to take root downwards and unite the outer sect, laying the foundation for the war between immortals and demons. Practice shield skills, pass on information, unite the demon clan, guard the retreat, and twist the outer disciples who no one cares about into a single rope. The Demon King sneaks around and attacks? She is not afraid. Is the Immortal Sect in danger? She led the outer disciples to stabilize the rear front and save the entire mountain. Xia Rou: Isn't it just to get ahead? Taking the mass line is also the way to go. When everyone came back to their senses, the nameless NPC had already stood at the highest point of the Immortal Sect and became the senior sister respected by everyone. Even the cold ancient true god handed her a spiritual fruit: "Next time you act, take one with me."
