Ancestral Heaven Mysterious Spirit

How should the reborn Lin Chen protect his cute and stupid sister in this world of resurrected spiritual energy? Passerby A: We have good qualifications and can practice faster than you. Lin Chen: I have the golden finger of time travel, and my cultivation speed is 10,000 times faster than yours. Passerby B: I have strong mental power and can contract many contracted beasts. Lin Chen: What kind of contract beasts are you talking about? Are they as strong as a divine beast like mine? Passerby C: I have powers, do you have them? Lin Chen: What kind of power does your superpower have? Can it destroy the world? Passerby King: I am older than you, so I took your sister away, hahaha! Lin Chen: This is not okay, my sister is mine... This is a young man who kills demons and evil spirits in a different world where spiritual energy is revived. Of course, the most important thing is to protect his silly sister!
