In the future urban "Dome City" where technology is highly developed but classes are solidified, Lin Yuanhang, a lower-class resident, makes a living by scavenging and struggles to survive on the food and clothing line. In an accident, he was pierced into his body by a mysterious black metal fragment, which accidentally activated a system called "All Things Upgrade".
This system can analyze and upgrade everything he comes into contact with, from rusty wrenches to scrapped mechanical prosthetics, from dilapidated drones to the wreckage of star battleships. Each upgrade requires the consumption of "source points", which are obtained by decomposing useless materials.
Since then, Lin Yuanhang's fate has undergone earth-shaking changes.
"A broken kinetic energy dagger? Upgrade! Become a high-frequency cutting blade!"
"A scrapped reconnaissance drone? Upgrade! Become a hummingbird killer with electromagnetic interference and stealth capabilities!"
"An incomplete powered exoskeleton? Upgrade! Become a personal armor that roams the battlefield!"
Relying on the ability to turn decay into magic, Lin Yuanhang rose step by step from a scavenger at the bottom of society, stirring up the storm in the entire Dome City, and finally set his sights on the deep sea of stars. This is a cool sci-fi story about a little person who relies on a golden finger to constantly break through himself, upgrade his equipment, and finally reach the top of the universe.
