"Imagine the Earth as a sheet of paper, and a stick of incense touching a certain spot on it. Once the paper is subjected to high temperatures, that spot will begin to blacken and then ignite. This is precisely the predicament faced by Art Building."
"We've managed to cool down the area around Art Building and set up sufficient protection to prevent the temperature from spreading to other areas."
"The root cause is that which produces high temperatures. The continuously spreading heat is what you call those fluctuations. Once any living being's 'ignition point' is lower than this temperature, it will ignite."
"And to avoid ignition, besides strictly filtering out materials with low ignition points, there's also the need to control the distance... If the distance is not far enough, no matter how low the ignition point, it will still be affected."
"The range over which the high temperature spreads is termed 'Domain.'"
"The Contamination Domain."
