Progress in Killing the Protagonist

Qiao Yunshu dug out a piece of paper in the forest. There are two lines written on the piece of paper: [Progress of killing the protagonist] 0/? [Assist a real protagonist on stage] 0/1 He stared at the word "protagonist" and turned to look at the boy next to him with light blue hair and red pupils whose village was destroyed by a monster. He has a miserable life experience, is gifted, and is taciturn. ——No more running, this is the protagonist. So Qiao Yunshu decided to be the supporting actor beside him. It wasn't until much later that he discovered that the system had written the correct answer from the beginning. It's just that he can't understand it.
