I, the Righteous Son, Am Actually Bound to the Demonic System

Fang Ping traveled through time and became the holy son of Xuanqing Sect, one of the nine sects and ten sects, and he was a candidate for the next sect leader. Xuanqing Sect is famous as the orthodox sect in the Nine Provinces Holy Land. Fang Ping is destined to be a lucky person born in Rome, who can enjoy life to the fullest, practice peace of mind, and welcome a better tomorrow. Unfortunately, I awakened the 'Counterattack System'. If you want to counterattack, just counterattack. Anyway, the starting point is so high, so I'm not afraid. But something wasn't right looking at the mission. "How come my majestic holy son has become Li Qianchou, a disciple of the Demonic Way? I am still just a minor player in the first level of Qi training realm." "If you want me to inquire about the sect's information, should I inquire?" "If you want me to help the devil deliver a message, should I deliver it or not?" "If you ask me to help the demons kill the righteous monks, should I kill them or not?" … Gradually, I discovered that the system could have other ways of playing. Helping the devil deliver news, doesn't that mean he knows the news about the devil? Even the demon spies buried in the righteous path were found. As for killing the righteous monks? Just kill the traitorous monks. Well, This system is so easy to use. From then on, Fang Ping held the title of Holy Son and continued to eradicate the demonic forces in the Holy Domain, becoming the leader of the Righteous Alliance. And his status in the devil's path also increased, and he eventually became the devil emperor. "It's time for the two paths of good and evil to merge."
