I Am a Scavenger of All Realms in the Demon Sect

Others' golden finger: Be invincible at the beginning, every second of the day. Lin Yan's golden finger: Stay tight, don't wander, live on! After traveling through time and becoming an abandoned son of a deposed sect, and then being thrown into the Demon Sect's handyman camp that eats people but not spits out bones, Lin Yan thought he was getting a script from hell. Until the [Gou Daoxuanjian System] is bound: "Want to survive? Remember three things: first, pretend to be weak, second, avoid fighting, and third, pick up the slack." Additional ability [Xuan Jian Shu]: can see through cultivation disguises, treasure traps... And the truth of the world. So, when the genius of the Demon Sect fought for an "ancient spiritual crystal", Lin Yan silently picked up the real good thing in the corner - a ball of "world filth", and after absorbing it, his cultivation level skyrocketed. Fairy Zhengdao dismissed him, but he saw the "ominous Taoist body" entangled in her destiny, and she would become a demon in the future. The world-destroying ferocious beast came, and the monks were in despair. Lin Yan was about to flee under the urging of the system, but the Xuanjian Technique suddenly marked the ferocious beast's "core pollution source" - it turned out to be the remains of a waste mine that he had secretly "purified" yesterday. Later, on the battlefield between immortals and demons, Lin Yan, who had just "low-key" repaired the cracks in the world, sighed as he saw the gods and Buddhas all over the sky killing each other for the "opportunity to ascend". He said to the system in his mind: "Report, there are people here who are destroying the ecological environment and affecting the sustainable development of the world."
