Demon Sect Tutor, I Rely on the Magic Mirror to Pretend to Be a Boss

Fang Lin, an ordinary social creature, was lured into the Demon Sect as a tutor by his unreliable cousin. I thought I was just teaching Chinese, but I found out that my employer was the murderous Princess of the Shadow Demon Sect! What's even worse is that Her Royal Highness the Princess wants him to decipher the righteous secret "Huang Ming Jue" within one day, otherwise he will be quartered on the spot! Just when Fang Lin was desperate, the mysterious bronze mirror [Red Nether Realm] suddenly recognized its owner and transferred his soul to the senior brother of Qingfeng Sect - he had perfect foundation building and great talent, but... He was in debt of 700,000 spiritual stones? ! Bite! Mission: Help junior sister break through the core formation stage. Reward: Bring an ability back to the body! Fang Lin:? ? ? On one side is the butcher's knife of the Demon Sect Princess, on the other side is the debt crisis of the Immortal Sect's genius... See how modern social animals rely on "loans to cultivate immortality" and "magic mirror plug-ins" to repeatedly jump between the worlds of good and evil, pretending to be bosses and trying to survive!
