The ancient mech race!

"What exactly are you?" Xia Fei grimly asked.

Dimsky was in disbelief. Feigning calm, he replied, "We're robots, of course. I am Dimsky and he is Warstar. Do you have some other questions?"

Xia Fei shook his head. "I've said it before: None of you are ordinary robots. Your technology has far surpassed the limits of ancient mankind. While you can deceive others, you can't trick me. As one of the few people in the Panhuman Alliance who has studied ancient technology, I know very well that they never developed liquid metal. Neither the present nor the past human civilizations have ever had this kind of technology."

Dimsky and Warstar exchanged glances, both robots falling silent.

"The actual bodies of Warstar and the Sentinel Goddess both have a very special symbol which looks like a snowy mountain. If my guess is correct, the original bodies of Dimsky and Xana probably have the same symbol."
