Fantasy: I'm Really Not the Villain Behind the Scenes

Traveling through the world of cultivating immortals, Li Wuxian became a useless person in cultivation, and also received an equally "useless" emperor engine system. As long as he is nervous, his heartbeat will accelerate, which will cause strange phenomena in the world and all kinds of horror; as soon as he opens his mouth, it can resonate with the great avenue, with the special effect of following his words! He also inexplicably accepted female apprentices, who were both stunningly beautiful and talented, but all of them went astray and became demons because of his "teachings"! "The white-haired witch from Yunshang Immortal Palace deceived her master and destroyed her ancestors. She was a treasonous person. I heard that her master's surname was Li." "The nine-tailed demon fox in the Northern Territory leads all demons and brings disaster to one side. I heard that her master's surname is Li." "Empress Chixiao covers the sky with one hand and governs the country violently. Her master's surname is also Li." As time goes by, people increasingly believe in the rumors that there is a big boss behind the scenes who is secretly controlling these female devils... Li Wuxian:? ? ? I'm just a Qigong practitioner...
