Useless? I Contracted a World-Destroying Dragon

A programmer who dies suddenly transmigrates into another world as a good-for-nothing young master. At his family's coming-of-age ceremony, he is mocked in front of everyone: “You can't even light a piece of firewood.” But when he uses the logic of code to crack a magic formation, what he contracts turns out to be a dud egg? The next second, a dragon's claw blots out the sky and tears the heavens apart. “Whoever called me useless just now, come collect twenty lashes!” As a world-destroying black dragon's oppressive aura engulfs the city, watch a burned-out office worker use the mindset of a game designer to crush the geniuses of another world!
