As it turned out, Nami was an innocent, good child.
Upon discovering that her companions were living in deep trouble, she immediately set her mind to work, communicating through Tesla Technology's internal network and sneakily sent an address to Song Lan's mobile phone before the lunch break.
This confirmed Song Lan's guess, and it was the main reason he had revealed this information to Nami.
He speculated that bioroids had some kind of secret communication method among themselves, no different from social networks among friends.
As someone from the year 2020, Song Lan had always been deeply interested in artificial intelligence. In his era, AI was still in its infancy and nowhere near as intelligent as it was now, and the social problems caused by the widespread development of this technology had always been a topic of discussion among science fiction authors.
