Cultivation! Start with a Loan

In the world of immortality where everyone practices hard work, the male protagonist awakens in a cross-border cave and can barter with all the heavens and worlds. He discovered that the Bigu Pills he used at home were high-energy nutritional pills in the wasteland world, and the lowest-level fireball talisman was a weapon of mass destruction. While others were practicing hard, he directly injected spiritual energy to improve their cultivation, became king in the wasteland world, and sold immortality packages in the interstellar world. As a result, the style of the world of cultivating immortals also changed: the Demon Lord was obsessed with mecha modifications, the Saint started a doomsday live broadcast, and the male protagonist looked at the spiritual veins transformed by the nuclear power plant and fell into deep thought - what kind of immortal am I cultivating?
