"Chu Mu..." Ye Qingzi could clearly feel Chu Mu's hand trembling slightly.
Just from listening to Chu Mu's description, Ye Qingzi could imagine the scene of those sky-covering black butterfly wings.
However, no matter how much she tried to imagine, she probably couldn't truly estimate how many Black Spirit Butterflies were there.
Chu Mu's expression became extremely solemn because he could feel that those Spirit Butterflies were not all at the Servant Level, the low-level life forms. The ones that attempted to attack Chu Mu before were all at the Commander Level, and once these Commander-level creatures numbered in the thousands, they would pose a significant threat even to an Emperor-Level.
"Exactly how many? You're a Soul Pet Master, don't tell me you lack even this level of judgment," Elder Duan said somewhat dissatisfied upon seeing Chu Mu suddenly fall silent.
"A forest..." Chu Mu said with a calm voice.
