In the Wasteland, My Items Can Be Synthesized Infinitely

When the apocalypse comes, others fight for a pack of biscuits, but I turn my backhand into a table full of men and women! Traveling through the wasteland, I started in a broken Internet cafe. Fortunately, the infinite synthesis system was activated. Two packs of expired instant noodles? Synthesis→Steamy seafood ramen! A rusty iron knife? Synthesis→A hundred-refined short blade that cuts iron like clay! A weak kitten? [Synthesis] + [Mutated Crystal Core] → A unicorn war beast that controls thunder and lightning! While the survivors were still struggling to survive in the ruins, in my safe house, the cold female president was acting coquettishly with me for a sip of ice Coke. Don't ask me why I'm so showy, just ask that everything can be combined, the entire wasteland is my material package!
