The Koi Property is a mysterious and elusive concept.
It might only work for a particular person or certain types of people, but it could just as easily bring good luck to everyone.
However, people with this property won't have "I am a Koi" written on their foreheads, so it's hard to tell if it really exists.
As for figuring out who his own Koi is, Xu Ran had a simple and straightforward method: whether he could consecutively pluck the highest-level skill his plucking fur ability could presently get from them.
This method had always worked out for him in the past.
Back when he was still in Qingzhou City, Xu Ran's plucking fur had just upgraded from D-level to C-level, and the highest skill he could get went from one star to two stars. Liu Gu, who kept giving him two stars skills one after another, became his first Koi.
