After the Illusory Fire hit the final monster, the monster quickly entered the Illusion Realm without even a struggle.
But the final monster knew he was entering the Illusion Realm, so at the moment he entered, he dragged his good thoughts into it. Then, just as the Illusion Realm was about to close, his evil thoughts escaped.
However, his good thoughts remained in the Illusion Realm.
In reality, only a moment had passed. The Illusory Fire burned on the final monster, but it only burned for a few seconds because the Illusory Fire was consuming the part of his soul representing good thoughts within his mind, and the final monster was controlled by evil thoughts, so no flame burned here.
Although the final monster escaped from the Illusion Realm, he was still drenched in cold sweat. If he didn't have good thoughts within him, or if he hadn't managed to replace them, he would have sunk into the Illusion Technique.
