I'm Being Observed by Evil Spirits

The senior brother is loving, the senior sister is gentle, the junior sister is cute, and the master is considerate... Su Bai always felt that these were blessings from helping the old lady cross the road in his previous life. Until one night, he suddenly discovered that he had been being observed... The evil spirit revives, and all living beings are devastated. Weird, evil, nightmare, indescribable. Su Bai came with a black jade pendant, absorbed Taoism, and discovered the truth of the world step by step.
