You Say You Are a Scumbag, How Did You Become the Savior?

Sun Yu just wanted to be a scumbag quietly, getting 27 points on the test, huddled in the corner of the classroom, and could only feel sad when his eraser was stepped on. Until that day, the whole class was laughing and forcing him, but the school beauty Chen Xinya pressed "one button to challenge" for him. He thought this was just a battle of dignity between bad students, but he didn't expect that—— In the depths of the lake, there is an endless abyss; behind the test paper, there is a supernatural awakening! A mysterious signature from an ancient temple, a strange young man in a suit, a sudden hunt by a strange beast... And the girl who always smiled at him under the sunset seemed to already know everything. "Sun Yu, you have never been a waste, you are a brave man." When physics problems become magic spells, when these are upgraded to games with gods, He held the Kuromi pendant in his hand and finally raised his head: "This time, I won't run away again."
