The Most Powerful System but All the Tasks Released Are Sandbox Missions

The male protagonist is a little loser who is looked down upon by everyone. One day, he acquires the system. Every task issued by the system is extremely outrageous (such as "Run upside down three times around the playground to reward magical skills", "Shouting "I am the most handsome" in front of the whole school to reward clairvoyance"). The protagonist is forced to try crazily on the edge of social death, but the rewards obtained after each outrageous operation make everyone stunned. The sense of absurdity + the contrast are refreshing, and the reader jumps repeatedly between "laughing to death" and "fuck".
