Doomsday Survival: Me! Start by Synthesizing an Aircraft Carrier!

Su Yu traveled through the parallel city, but was told that the world was entering a countdown to the outbreak of disaster. Within half a month, volcanoes around the world will erupt together. At the same time, the glaciers melted completely. Humanity will enter the ocean age! There may even be space technology emerging and alien invasion in the future! Fortunately, Su Yu had an infinite synthesis system. He decisively sold all the assets left by his parents and... Opened a scrap company. When others laughed at Su Yu for being the king of scraps, he had synthesized a new generation of fully intelligent control cabins from countless scraps! When his girlfriend was about to break up, Su Yu was only one step away from becoming a maritime aircraft carrier! A horrific global catastrophe? No, for Su Yu, that was just the beginning. Terrifying alien invasion? Su Yu smiled at his sister: "It's time to break out of Blue Star and fight all over the universe!"
