Global Shrinking: Building Humanity from the Laboratory

When we wake up, humans around the world shrink 100 times! Civilization has regressed back to primitive times. Cockroaches are as big as vicious dogs and rats are like ferocious apes. Our former homes have become a hunting ground of life and death with ambushes from all sides! While everyone was struggling for a sip of water and a piece of biscuit, Chen Entropy, a doctor of materials science who was trapped in the State Key Laboratory, smiled. Are the outside world still digging wood to make fire? He has used electrolyzed water technology to light up LED shadowless lamps. Others use stones to drive away ants? He has used a 3D printer to create a repeating crossbow the size of a matchbox, using spiders as a strategic material reserve. When the barbarian king of the "Tribal Alliance" brandished a spear polished by sewing needles and clamored to flatten everything, Chen Entropy stood on the "Main Chassis City" he had built with his own hands. Behind him were legions equipped with electromagnetic rifles and exoskeleton armor. Next to him, there was the hum of a micro-nuclear reactor. "Welcome to... My time." This is a hard-core story about using knowledge to restart the industrial revolution, using technology to crush all dissatisfaction, and bringing human civilization back to its peak from the ruins on a scale of 1.75Cm! Survival is just the beginning; conquest is the destiny!
