Ordinary warriors might not be able to tell anything from this. But Nangong Mingzhu was a true immortal cultivator and naturally knew the difference between Deified Soul Power and ordinary Soul Power.
Mo Wen had Deified Soul Power, and this was something very odd and shocking. It was beyond her range of comprehension.
Generally speaking, there was only one way for this situation to occur to a warrior. It would only happen if an immortal cultivator with a primordial soul took over the body of a warrior.
However, an immortal cultivator who could take over the body of a warrior was usually an existence beyond the Primordial Soul Realm. Would such a powerful character take over the body of an ordinary warrior? It probably would not be difficult to take over the body of an immortal cultivator in the Primordial Soul realm. It was practically impossible to take over the body of a warrior unless it was under special circumstances.
