After a high school reunion, the young man sat down on the beach shore, and mumbled to the sky, “God of Novels, you are unfair.

Are you shitting with me, you bastard?!”The system replied, “Host the condition for activating the system is to get married.”Hao Ren could not handle it anymore and cried out loud as he complained about this condition. He was not good-looking, and neither was he wealthy, who was going to marry him?Tired, he spent the on the beach. When he was returning home, he passed by the marriage registering center. He sighed for his fate but suddenly, a beautiful lady asked him, “Hey, do you have any identity card on you?”Hao Ren nodded in a daze, and the lady dragged him inside the office. The young man was yet to register what happened to him when an automated voice sounded, “Host, congratulations on getting married. Omnipotent Husband System is now activated.”...Years later, Hao Ren became an entity many people wished to meet.
