So: All drones have a program called "Absolute Solver" but for most of them it is turned off (Exeptions is Doll, Uzi, Yeva, Nori etc.). The main goal of this program is to collect SINGULARITY. When it collects it, the drone becomes murder\zombie drone. The Zombie drone are actually quite similar to Dissasembly drone for few exeptions. First: They have the flesh parts (Wings, tail etc.). Second: They can regenirate FULLY, but Dissasembly drones cant. The CYN is an Administrator for the group (The group of N, V, J maybe more), and CYN can block the entry for the team to Absolute Solver (Absolute solver is a whole program that contains a lot of different functions). The CYN is now a some kind of Virus that spreads within a Worker drones with access to Absolute Solver. And about Worker and Dissasembly drones, they have different S\N (Serial Number). Dissasembly drones have S\N like this: (first letter of the name) 0x0000000. And Worker drones have these: # 0000. At the scene where Teacher talks to Khein, when we see his POV in the left bottom side of the screen we can see his serial number. When N restarts (Thanks to J) from his POV when he restarts we can see his serial number (Which is N - 0x0010010). A bit about Absolute Solver: When Uzi is talks about k*lling all humans, when she is laughing we can see in her eye that "AbsoluteSolver = False" and then after a few frames "AbsoluteSolver = True", so that means that Drones can turn it on on VERY specific moments. That all what i gathered for now. Stay tuned! (watched these videos for more explanation: https://youtu.be/nSlpgFxt6O4 https://youtu.be/w3JLw-WAwdo https://youtu.be/uRWsZd5zCfE )
