Raventon took out a folding magnifying glass and observed the traces for one or two minutes, then folded the magnifying glass and said, dazed:
"Forbidden passage ceremony."
Wu Chang praised him: "It seems your mysticism skills aren't too bad. If you could go a step further and restore the traces of the mystical ceremony, that would be even better."
Raventon asked in puzzlement: "How did you discover it?"
Let's not talk about the forbidden passage ceremony on the wall, which had already been cleaned up by someone. The cleaning method was extremely clever, leaving almost no trace.
Even if traces were left, he could be sure that Wu Chang had never seen that trace before.
Wu Chang was standing about ten meters away, appearing thoughtful while staring into the air, and almost in the blink of an eye, he seemed to receive divine enlightenment, discovering hidden clues.
Faced with Raventon's inquiry, Wu Chang naturally said: "I mentioned, it's by inspiration."
