Global Catastrophe: My Knowledge Can Be Directly Monetized

Tides of psychic energy sweep across the globe, circuits go out, civilization collapses, and monsters descend from the rifts. Ling Zhe, an ordinary librarian, was bound to the [Temple of Universal Knowledge] system during the disaster. Knowledge has become his only currency and weapon. When others were struggling to survive in the ruins, he exchanged the "Basic Purification Technique" for a mouthful of clean water; When others used sticks to fight monsters, he silently opened "Simple Gunpowder Preparation" and "Basic Enchantment"; When the various forces fought for a piece of bread, his stronghold had realized psychic irrigation and steam power supply. What others awaken is power and lightning, what he awakens is the wisdom that drives the entire civilization process. Is it to restart electromagnetic technology and restore its former glory? Or embrace psychic energy and move toward personal transcendence? Or... Take an unprecedented fusion path and create enchanted firearms and psychic mechas? Let's see how Ling Zhe uses the knowledge in his mind to ignite the spark of civilization in this broken wasteland.
