Hearing Feng Xue bring up Kaidan, Old Li's voice grew a bit weathered—
"Whether it's Anomalies or rumors, in the end, they amount to nothing. Given some time, the influence they've manufactured will gradually fade away. But Kaidan is different—it has become a cultural symbol. If you can embed your existence into a region or even a country's culture, becoming common knowledge that is universally recognized within a certain area and does not fade with the passage of time, then you have become a Kaidan. At that point, your label will integrate further and be sublimated into a more powerful form, known as a 'Kaidan entry.' Of course, I've only heard about this; I don't know the specifics."
"Hmm, like the 'Hanako of the toilet' kind of thing?" Feng Xue, finding Old Li's somewhat evasive explanation, couldn't help but recall the nearly household Kaidan legend of the Eastern Country.
