Wasteland Refiner, from Pistol to Sky City

In the year 2291, strange beasts are rampant. Chen Feng traveled through time and became a bankrupt repairman. Creditors broke down the door and rats invaded the city. In a desperate situation, awaken the "Item Refining Map System" - smelting all things + crit divine equipment! The first crystal core pistol, unlimited bullet version, can blast through the corrosive rat tide; The scrap metal plucked from the pile of steel-toothed dog corpses was transformed into a ten-hole shotgun, blasting the B-class beasts; When everyone laughed at him as "an ant with no superpowers", he took out his backhand: Acid Grenade: Melt the Cyborg Army! Living Armor: Hardly resistant to nuclear blast radiation! Anti-gravity fortress: lift up the sky city and rush towards the stars! The godfather begged for cooperation, the queen of the chamber of commerce gambled her life on investment, and the enemy spy stole and copied pictures... He uses weapons as chess pieces to make moves in the wasteland chess game, and the SSS-level alien beasts are just whetstones on the way forward. "Earth? It's just my weapons testing ground—— The next stop is to crush the cage of alien civilization and create a way out for human civilization! "
