In Ice Age, I Can Become Stronger by Mining.

The sun goes out, the world freezes, and cities turn into frozen soil. Lin Ye was trapped in an abandoned mine and relied on a pickaxe to cut through the desperate situation. A former geological team member, his parents died in a mining accident, leaving him alone with only his father's copper compass. The cold wave is raging, and the weak freeze to death in pieces. The source of heat is power. He traded lives for lives, killed predators, and gnawed on frozen meat to survive. Awakening Gold Finger: Every time you mine a unit of minerals, your physique will be +1, and your tools will be strengthened simultaneously! He drilled ten meters into the rock to find pyrite, and broke off huge boulders with his bare hands; he dug a hundred meters deep to touch granite, and his right arm still tore apart. The system unlocks geothermal blueprints, furnace forging, sonic weapons... From lone miners to establishing underground camps. Collect survivors, fight looting groups, and destroy brotherhoods, all the way to the end! Dig through the earth's core, ignite the artificial sun, and restart the fire of civilization - this pickaxe is going to the end of the universe! This novel and its characters are purely fictitious.
