Of course, upon closer analysis, that metal automaton might not be as powerful as imagined. It was just that due to various objective and subjective limitations at the time, the combat strength of the Advance Team was restricted, which is why they were so embarrassingly defeated by her.
Even if that metal automaton was stronger, it couldn't possibly be a match for Fulajie'er. After all, Fulajie'er is a demigod, an immortal deity. It would be easy to deal with an automaton driven by magical power, as long as one could find the right way to do it.
And the way to do so, Fulajie'er had actually found it during the recent combat. The Defense Shield she deployed could effectively interfere with and restrict the metal automaton's movements. However, at the time, due to the limited magical power in the passage, she couldn't absorb more magical power to interfere with the automaton's movements.
