"Where did the Evil Ghost get a large number of Yin Horse Underworld Chariots from?"
Qing Songzi frowned.
Xiao Mu said casually, "Yin Horse Underworld Chariots are special, they have to be made by humans using Mutated Yellow Paper, and then burnt, only then can they be obtained by evil ghosts and become Yin Horse Underworld Chariots."
"That's what I thought too, which means..."
Having said this, Qing Songzi shuddered again, involuntarily looking at Xiao Mu.
Xiao Mu nodded slightly at Qing Songzi.
Apparently, they both had the same idea and were thinking of the same scenario.
Qing Songzi said with a changed face, "Someone on the human side has betrayed humanity, using Mutated Yellow Paper specially for the Evil Ghost to paste Yin Horse Underworld Chariots!"
Xiao Mu added, "It's also possible that they were forced."
Qing Songzi looked solemn, "Thank Mr. Mu for reminding, anyway, I have to investigate first and look for traces of the Yin Horse Underworld Chariot."
