After Going Bankrupt, I Transmigrated to the Apocalyptic Wasteland to Become a Middleman

[Travel Between the Post-Apocalyptic Wasteland and the Modern World + System + Farming + Cross-World Revenge + No Female Lead + Multiple Female Characters + Unlimited Superpowers + Technology Exchange + Dual Storylines] The day Li Dalong went bankrupt, his gold-digging girlfriend humiliated him, his partner stole his technology, and the partner's son tried to steal his girl. The next second, mysterious purple light struck him in the face. When he opened his eyes again, he could travel between the post-apocalyptic wasteland and his hometown's world! Before him: Mutant zombies gnawing on human bones! A giant mutant crocodile capsizing a boat! Superpowered bandits abducting women! But Li Dalong only laughed. “How is this hell? It's my very own wholesale superstore!” [Sell supplies and technology with one hand, beat the hell out of my enemies with the other!] The wasteland: → One pack of spicy strips earns the worship of a scavenger brother! Compressed biscuits? Trade them for wasteland crystals by the pound! → Stockpile tens of thousands of tons of supplies in the System space! Need a diesel generator to fight the cold? I'll clear out the whole hardware store! → Inject a self-made gene serum? A little girl instantly becomes a sonic killing machine! A mermaid's tail smashes a bandit's skull! → Recruit a fierce all-female combat squad: “A partnership? The supplies are yours, and I... can be yours too!” The modern world: His enemies, father and son, steal his patent and claim they invented it themselves, celebrating on a worldwide livestream: “This technology is worth hundreds of billions!” The protagonist sneers: “You like stealing? Here's a VIP spot at your own funeral, for both of you!” The whole internet erupts! Meanwhile, he takes his supplies back to the apocalypse and lives like a king. When an iron fortress explodes into fireworks over Bone Bay and a hundred thousand bandits kneel and beg for mercy Li Dalong stands with one foot on a mountain of crystals: “What's the rush? Next target: steal a starship and use it as a yacht!”
