Doomsday Survival: I Built an Aircraft Carrier from the Start!

Su Yu transmigrates to a parallel modern city, only to be told that the entire world is counting down to a disaster. Within half a month, volcanoes around the world will erupt simultaneously. At the same time, the glaciers will melt completely, ushering humanity into an age of oceans! And in the future, space technology will emerge, followed by an alien invasion! Fortunately, Su Yu has an unlimited synthesis System. He promptly sells off all the assets his parents left him and... opens a scrap company. While others laugh at Su Yu for being the king of junk, he has already synthesized a new-generation, fully intelligent control cabin from countless discarded items! When his girlfriend wants to break up, Su Yu is already just one step away from synthesizing an aircraft carrier! A terrifying global disaster? No, to Su Yu, that's only the beginning. A horrifying alien invasion? Su Yu smiles at his little sister. “It's time to leave Blue Star and fight our way across the entire universe!”
