As they were talking, the voice of the ghostly thing came from Lin Yi's sea of consciousness.
"Lin kid, this mountain array is interesting! With the city as the base of the array, the buildings as the array patterns, and the flesh and blood as the driving force, it was truly peculiar! It was indeed a little evil, but its power was really not weak! How about it, do you want this old man to help you study it?"
Lin Yi was taken aback as well-it'd been a long time since that thing last appeared."I say, senior ghost, it's rare for you to take the initiative to speak! Furthermore, he even offered to help? Did the sun rise from the West?"
"Ahem, I say, Lin kid, can't I help you? How was it? Why don't you beg this old man and let this old man help?"
"Oh, I'm not begging you. I'll do some research on my own!"
"I say, Lin kid, you can't do this. You know, we share the same fate. I don't want to see you get killed by this formation!"
