There are no living people in District 9, only parts that are still alive.
Lu Yuan repairs home appliances and occasionally repairs people. His goal in life is simple: save enough money to replace his "second-hand heart" that can stop beating at any time, and then go uptown to see the real sun.
Until that day, he picked up a "black box" that he shouldn't have picked up, and hacked into a military mecha belonging to a large company.
Faced with a wanted manhunt all over the city, Lu Yuan sighed and spread his hands towards the murderous pursuers:
"To be honest, it was the one who started the attack. I was just a maintenance worker passing by... Hey, don't slap me in the face, the prosthetic body is very expensive!"
In this era where flesh and blood are weak and machines are soaring, Lu Yuan decided to use the rules of the old era to teach the new world a lesson.
