KO One Sign-In System

I transmigrated into KO One and bound myself to a sign-in System.

All I wanted was to keep my head down and watch the show, but my strength wouldn't let me.

While Wang Da Dong was still congratulating himself on breaking ten thousand battle points,

my warehouse was already overflowing with SSS-rank martial arts manuals I treated like scrap paper.

Teacher Tian Xin's safety? I casually signed in and got a barrier that could block space and time.

Then one day, Black Dragon's lackeys surrounded the classroom.

I yawned and pulled out the sign-in reward from under my desk...

“Hey, you're blocking my sunshine.”
