Battle with Dawu IEHD

Bad news: Traveling through the battlefield of immortals and demons, reaching the third level of Qi refining, you will be blasted to pieces in the next second! Good news: Awaken the [Yuanchu Demon Ancestor] template, and your bloodline will suppress the demons forever! The first mission of the system: save the dying contemporary demon! I bravely shouted loudly: "You evil disciple, why don't you kneel down!" Under the gaze of everyone, the demon king who had dominated the world actually knelt down on the spot! I rescued him, but I was shocked to find that this kid was actually the strongest undercover agent sent by the Immortal Sect! He pretended to be respectful, but little did he know that all the information he had was fake news fed by me! Many years later, I trapped and killed all the main members of the Immortal Sect. The undercover disciple I personally trained has become my sharpest knife to destroy the Immortal Sect!
