High School Self-Discipline to Kill Ghosts, the Level Is Soaring All the Way

It has been eighteen years since Zhuxie traveled through time. For eighteen years, I have been waiting for the legendary golden finger every day. It wasn't until the first month of the first year of high school that it finally came - self-discipline can improve your appearance, figure, and IQ, as simple as you want. At first, Zhu Xie thought it was just an urban campus scenario, where he attended classes honestly, occasionally acted cool, and lived an ordinary life. Until he accidentally broke through a layer of window paper - there was evil hidden in the darkness of this world. Things that ordinary people couldn't see or touch were about to move in the shadows. It was at this time that his golden finger, who had followed him quietly for sixteen years, quietly began his second evolution. "I... Like it very much." Zhuxie stepped on a pile of twitching evil spirits, looked down at them, and grinned. The laughter was long and muffled, as if it was forced out of the chest, with a bit of a crazy Uchiha flavor. "If you don't have a good time after traveling through time, what's the use of it? Are you worthy of my name - evil spirits?" The evil spirit underneath was desperately squirming back, shouting as it ran away: "The old people and children go first! Let's come to the rear! Stand behind!" Xie Sui: "Hehe, I must live on." —— [In the early stage, campus life is the main focus. The protagonist slowly becomes stronger through self-discipline.
