System 8888, from an advanced civilization in the Federation, was accidentally swept into a space-time tunnel. When its energy ran out, it had no choice but to find a Host.
Yi Shu had spent years as an experimental subject and knew nothing of human emotions. Rescued one day, she still couldn't fit into normal life, and then she happened to meet 8888.
One person and one System: one needed energy, the other wanted some fun. They were a match made in heaven.
(Harem of admirers, indulgent power fantasy. Don't expect logic; the pairing is up to you.)
