Traveling to the end of the world, Jiang Ning awakened the sign-in system.
Sign in at the supermarket on the first day and get SSS-level material space.
Sign in at the research institute the next day and get the zombie virus serum.
Sign in at the military base on the third day and get one million loyal troops.
Looking at the squad of superpowers fighting around him, Jiang Ning kept a low profile and hid his strength.
Until the teammate who stabbed him in the back knelt down and begged for help, and his ex-girlfriend's boyfriend mocked him as a waste.
Jiang Ning sighed and slowly took out the walkie-talkie: "All zombies, put down what you are doing and come here to sign in."
