Although Zheng Qing could hear whispering voices from behind the bookshelf, he couldn't make out what they were saying, and he wasn't sure if they were people speaking or whispers of little ghosts.
But the round-faced warlock not only heard them but could also clearly explain the content of those whispers.
This instantly stirred Zheng Qing's spirit.
"I told you, that wasn't an illusion just now!" He seemed to have proven a difficult divination calculation principle and looked eagerly at Xiao Xiao: "You really can't hear anything?"
Xiao Xiao adjusted his glasses.
However, before he could speak, the round-faced warlock quickly defended himself: "It's not surprising that the Doctor can't hear them because those 'Law Book Liberation Association' guys talking are five or six bookshelves away in another corner. If I hadn't seen them just as I came in, I wouldn't have been able to identify them."
