Popularity System: This Sect Will Be Broken up Without Me

[Group portrait + single female protagonist + not invincible + easy] My name is Lin Luzhou, a time traveler, and I have lived alone in this world for twenty years. When I was sixteen years old, I joined the Yunzhan Sect and officially entered the path of cultivating immortality. During the past few years of staying in the Yunzhan Sect, most of the brothers and sisters around me have entered the outer sect, and only I am still on the second level of Qi training. I thought that I would just be invisible to everyone in my life, but I didn't expect that one morning early in the morning, I heard a familiar yet unfamiliar voice, and then I knew— In this world, I am just a sidekick. But now that I have obtained the system, I am naturally unwilling to give in. It seems that I am going to do something big! Etc! What the hell is the popularity system?
