Murder drones *next generation*

Serial designation Q was a murder drone for as long as he could remember... All he did was invade colonies for food in order to avoid overheating... That was until he met two new people from a particular colony... Z and A(also known as Alexa)... "it wasn't normal for disassembly drones to live together with workers", he thought...

Things go downwards when a new program, the reincarnation of the absolute solver, finds out about Z's true identity... Now in a situation where he and his friends could be destroyed at any moment, Q investigates the matter... how did the absolute solver reincarnate? Why was Alexa and Z hiding their identity? What was Z's real name? there were so many questions... It's up to them to save the universe like their parents did...
