At that moment, an inappropriate mechanical female voice popped into her head.
[You can sign in today, would you like to sign in?]
"Sign in," she muttered to herself.
[Sign-in successful, congratulations on achieving max level Singing Skill and max level singing techniques.]
Mu Lingyun: ...
What the hell are max level Singing Skill and max level singing techniques?
[Don't worry about those terms, just know that from now on, you're really good at singing.] The system stated haughtily.
Mu Lingyun remained silent, and then indeed found that various theories of singing, even various singing experiences, had appeared in her mind.
Mu Lingyun felt that this sign-in system was truly, a heaven-defying system.
You suddenly know things you've never learned before, as if you studied them for ten years, complete with various experiences as if you've been doing it for over a decade.
Incredible!
