Entertainment can be upgraded infinitely

With the unlimited leveling system, Lu Chen realized that he could level up no matter what he did, and there was no limit!

He casually hummed a few sentences, and the system notification said,"Singing skill proficiency 1."

He casually typed, and the system notification said,"Computer proficiency 1."

Just a few casual strokes…cough cough, you know what I mean!

"Lu Chen, is there anything in this world that you don’t know?”

"Yeah, I don’t know how to act cool!"

[System Notification: Good acting. Acting tough skill proficiency 1.]
