Yan Fei was shocked; this was the first time the Auxiliary Brain had initiated contact with him. In the past, the Auxiliary Brain would only passively accept his commands and lacked the ability to exchange information. This time, it actually took the initiative to send a message—what was going on?
Unfortunately, after sending such a message, the Auxiliary Brain went silent again. Meanwhile, an image of a rusty, circular gear appeared within the Auxiliary Brain's system.
This rusty, circular gear looked quite ordinary, with an odd shape like it was a component of something. But given how rusted it was, the part should have been unusable. Why then was it an essential item for a Drone Upgrade? And how could such a gear, which clearly came from an industrial civilization, end up being unearthed in Kenya and considered a historical artifact there?
