Transmigrated into Cat's Tea as a Background Character, the System Forces Me to Become a Workaholic

When other people transmigrate into Cat's Tea, they become either magical geniuses or awaken their bloodlines.

When Jasmine transmigrated, she got bound to a [Tea Beast Encyclopedia Collection System].

System: "Please collect a tea beast: 1 lop-eared cat."

Jasmine scooped up the white-haired someone beside her who was yawning. "Isn't this one right here?"

System: "...That's your deskmate, Longjing."

Jasmine: "..."

Later...

Longjing: "Why are you always following me?"

Jasmine pulled out the encyclopedia. "Be good and let me take a picture. Just one."

Qihong: "That book in your hand... Why does it have pictures of me as a child?"

Jasmine smiled. "It's a secret."

Later still, the Six Great Houses were all spreading rumors: a mysterious girl possessed a "book of destiny" containing information about everyone.

Jasmine looked at the System panel, which read [Encyclopedia Completion: 3/999], and silently shed a tear.

Who can tell me why I have to collect an entry for the Demon King too?!
