Song Meilin shook her head.
"He tried."
The smile on her face disappeared.
"But the strange part was..."
"No matter how many Pishachas were killed, new ones would eventually appear."
"Again and again."
"Their numbers would decrease temporarily, then slowly recover."
Su Mo immediately understood.
"Like cockroaches."
Song Meilin looked at him.
After a moment, she reluctantly nodded.
"... A rather unpleasant comparison. But yes. Very similar."
"Nobody knows where they come from. We have searched the surrounding mountains several times over all these years and still haven't found the source."
Su Mo rubbed his chin thoughtfully.
That sounded troublesome.
A monster population that naturally regenerated after being wiped out was definitely not normal.
"Our ancestor also searched for a permanent solution," Song Meilin continued. "Unfortunately, he never found one."
"He eventually realised that simply travelling through and eliminating the monsters once wasn't enough."
