The notion that it might be possible for living mechs to achieve success in willpower cultivators and break through may sound crazy, but it was not an entirely baseless guess.
Ves was already convinced that his third order living mechs did not differ too much from humans in terms of ego, intelligence, learning ability and emotions.
The main reason why living mechs still possessed clear differences was because their 'bodies' were far too different from that of a flesh-and-blood human.
Even then, regular interfacing with their human mech pilots allowed every living mech to gain a more human perspective. The longer the two parties interfaced with each other, the more they started to resemble each other.
Ves even theorized that if mech pilots paired up with their living mechs for over several decades, they would eventually converge to the point where they could naturally attain a state of operation union!
