"Grudge" came from Ghost Fog Mountain.
During that trial, "Grudge" was the origin of everything. Through various clues, Yi Lin had located and acquired "Grudge," and in that same trial, he had earned an SSS rating.
In other words, Yi Lin had already recklessly dived to the bottom of that trial.
To date, the growth direction and abilities of "Grudge" had not been fully unlocked, filled with mysteries.
"Grudge" was like a monster clinging to Yi Lin's forehead, siphoning "nourishment."
Whenever anything similar to "resentment," "curse," or "negative emotions" appeared around Yi Lin, "Grudge" would activate on its own, mischievously feeding itself on Yi Lin's forehead.
Coming to Shenzaki City, the malevolent thoughts that originally filled Shenzaki City should also be "Grudge's" sustenance.
But after "Grudge" was satiated, it seemed to disdain further feeding, and after the progress bar reached 100%, there were no other movements.
But now... it suddenly spiked again!
