Legend of the Living Heroes: the Man Behind My Background Board Battle?

Nangong Yu traveled to the Legend of Living Heroes, but he was not the protagonist Zhao Huo. He dressed up as a background character from the Nangong family. He also carries a mentally retarded AI assistant that only displays random advertisements to harass him, and has a bunch of weird and deceptive functions. Troubled times are coming, and he just wants to go home, but God doesn't give him this chance. In order not to die meaninglessly in the chaos of martial arts, Nangong Yu gritted his teeth and fought hard! He planned, he micro-managed, and he struggled to the death! Save the beauty, protect the Tang Sect, and become the hero of the world? Everyone, move to the back! What he did was just to live comfortably in this turbulent world! At most, I would like to help out a little out of conscience. Some people called him evil, while others praised him for being kind. Nangong Yu went his own way and never cared. But as time goes by, more and more people follow him. One day, when everyone pushed him to the position of alliance leader and faced the BOSS, Nangong Yu was completely confused: "No, I'm just a background board. Why are you pushing me out of the lane?" "Where is Zhao Huo? Can you help me?" Looking back at the people behind him, he saw the protagonist Zhao Huo giving him a thumbs up. "Wait, why are you hiding behind me too?" Although it is a fan fiction, people who have not read it before can still understand it, just treat it as a normal novel. Group portrait, multiple female protagonists, pseudo-system. There are many original plots.
