Fallen Abyss Mechanic

After ascending, Lin Zhou realized that the fairy world was not a paradise. In the Falling Abyss, there are thousands of monks who ascended from the lower world. They have no immortality, no identity, only a pair of chains and a pickaxe. Digging, turning stones, and being whipped. Day after day, year after year. Lin Zhou also wanted to accept his fate. Until he discovered that the energy utilization rate of the immortal's so-called "absorbing immortal stone" was less than 0.3%. And the "useless knowledge" in his mind can make this number become 30%, 50%, or even higher. Start with a piece of fairy stone residue. Start with a primary battery. Start with a rotating impeller. Lin Zhou didn't tell anyone what he was going to do. He just picked up a few things from the pile of junk every day, and knocked on them late at night under the moonlight. Then on an ordinary night, the entire Luoshenyuan heard the first roar of the machine. That voice has not been heard for three thousand years.
