The Rules Collapse, and Mortal Explorers Reconstruct a New World

Others travel through the system, but I only follow the "Wild Survival Manual" when traveling, and I have a mortal body that can be shattered by high-dimensional radiation at any time. The laws collapsed, the magic failed, the high-dimensional gods regarded me as nothing, and the abyssal beasts roared underground. I patted the mud on my hands: Water pollution? Use physical water purification to teach the magic tribe what science is! Sterilize the whole family? Use biological knowledge to make them eat! God's dimension reduction attack? Sorry, the first rule of survival in the wild: use everything to counterattack! I also picked up an alien tyrant with a ceiling of combat power, from "mortal being a translator" to commanding him to dig ditches, chop wood, and make clay pots. He could crush the continent with just a few fingers, but I pinned him down in the fields and farmed: "Mortal, just wait for me!" Me: Wait and see me use science to reconstruct this new apocalyptic world! (Hard-core science flow + mortal counterattack + alien tyrant + farming in the future, watch me use earth knowledge to overturn the entire magical future!)
