Cave Invasion: Saving Humanity Begins with Blacksmithing

Changes occurred in the world, the caves were invaded, and the human race was in crisis. Gu Fan traveled through time and awakened the krypton gold points system. Others started blacksmithing in three years, achieved modest success in twenty years, and entered the palace in fifty years. Gu Fan became a master in the blink of an eye. While others encountered bottlenecks in their cultivation and had trouble sleeping day and night, Gu Fan's cultivation progressed rapidly. The weapon-refining expert: "What? Custom-made magic weapons? No, no, no, I can't do it. You should go to Gu Fan. The magic weapons he forged are invincible at the same level!" Alchemy Sect: "Please ask the ancestor to make alchemy? The ancestor is not here, where has he gone? He went to Gu Fan to learn alchemy." The strong human being said: "I have been practicing hard for ten years and finally broke through to the eighth-level Martial Saint. It's time to settle accounts with the foreign race... What? Gu Fan kills the alien ninth-level Martial Emperor like a chicken?" Aliens from all realms: "That human monster is here, run away!" Gu Fan: "Want to learn this? I'll teach you, but you have to queue up and pay the money first." This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
