Yuan Xiao was reborn. Only after her death did she discover that she was living in a book. In the book, she was a fake heiress who did terrible things and made the real female protagonist look like a good person. After being reborn, Yuan Xiao decided to become a scholar. As long as she studied hard enough, she’d repeatedly get the opportunity to draw prizes and stop herself from being controlled by the storyline. She wanted to change her life. Yuan Xiao did not want the terrible fate of her past life to repeat itself.

She wanted a life that belonged to her! Other students looked down on her. She made sure to win as many prizes in competitions as she could and consistently claimed the number one spot in school. Some people suspected she might have forged her educational accomplishments due to her young age. She directly solved the toughest questions in the world to prove those people wrong. Did somebody mock her for not being able to do anything else but study? She’d show them her world-class piano-playing…

Yuan Xiao went down the scholarly path and never looked back. She was no longer the bad student she used to be. The smart student in school, who nobody dared to offend, forced her into a corner and nervously gave her a lollipop. “I just gave you a lollipop, the thing that I like the most. When will you be my girlfriend?” Yuan Xiao tapped on his chin and chuckled. “I’ll be your girlfriend if you get into Q College with me.”

Qin Chen crossed into Taiyi Holy Land as a sweeper, and at the age of sixteen awakened the system. As long as he signed in at different places, he could get different rewards.

Sign in at the Land of Emperor Ruins and get the world’s No. 1 Chaos Holy Body and the Chaos Emperor Sutra!

Sign in to seal the magic land and get the quasi-emperor soldiers!

Sign in at the Refining Hall and get the God-level Refining Technique!

Sign in at the medicine garden and get the medicine of immortality!

Sign in at the Imperial Palace and get the Emperor-level forbidden magical power ‘Resurrection from the Dead’!

…

Qin Chen thought that he would just sign in silently until the world was invincible.

One day, the relics of the Great Emperor will appear in the Holy Land, all the holy places, families, and ancient dynasties have come, and there will be an unparalleled demon king in the relics, killing countless powerhouses, ruling the world, and wanting to destroy the Holy Land.

In desperation, Qin Chen could only walk out, slapped the Demon King to death, and sighed: “I just want to be a sweeper and sign in silently. Why do you force me to take action?”
