Peter didn't ask further because he knew that the missing mecha might have been captured by the Mechanical Holy City. According to the timeline mentioned by No. 0 in front of him, what had happened ten years ago matched what Professor Eugene had said.
"No. 0, I want to leave this place. I have something very important to do. Do you want to stay here or come with me?"
"Oh, Master, please don't abandon me. Take me away. I've been here for too long." A very exaggerated and pitiable expression appeared on No. 0's face.
Peter hesitated. It wasn't that he didn't want to take away No. 0, but he was a little hesitant.
After all, it was inconvenient to bring it along. He still had to find Barker and the others.
No. 0 sensed that Peter was hesitating. In order to leave this place, it operated its mecha body to leave quickly, as if it was going to take something.
Peter stood still and watched No. 0 leave, wondering what it was up to.
