"Chu Mu..." Ye Qingzi could feel Chu Mu's hand tremble gently.
Just by listening to Chu Mu's description, Ye Qingzi could imagine a scene of black butterfly wings that covered the sky and land.
However, no matter how she imagined it, she likely couldn't truly estimate just how many black spirit butterflies were there.
Chu Mu's expression became extremely solemn because he could feel that not all of those spirit butterflies were low-level, servant creatures; the ones that had attempted to attack Chu Mu before were all commander-level, and once these commander-level creatures numbered in the thousands, they would pose a massive threat even to emperors.
"How many exactly? You're a Soul Pet Master, don't tell me you lack even this bit of judgment," Elder Duan said somewhat dissatisfied when Chu Mu suddenly fell silent.
"A forest..." Chu Mu said with a calm voice.
