[Alien cats + Earthlings, with reality and instances interwoven; a third-person ensemble story told from multiple perspectives; the protagonists have no special golden finger, and there is no central romance]
The Tonggong Exam is a selection test for residents of the Cat Palace.
A sudden accident sent the candidates in Examination Room 713 to the planet featured in their test paper: Earth.
The exam must go on. The candidates have simply become the cats' contracted partners. And what exactly is a contracted partner? An Earthling the cats begged the King of Hell to spare...
When the glass breaks, the door to the examination room shall open.
Pass the exam, earn a core stone, and return to the Cat Palace.
They fight gun battles in a QR-code maze, take on Cerberus in a metallurgy lab, and play a murder game in an apartment building...
But behind it all, it seems some people have found loopholes in the exam.
As the exam progresses, some mysteries from the contracted partners' pasts also begin to surface.
