Transmigrating to Cultivate Immortality: The Legend of Creation

After transmigrating, Li Xuan thought he'd started out as a good-for-nothing. He hadn't been dumped by his fiancee from the start, but he had narrowly escaped having his entire family wiped out. Yet as time went by, he somehow became a full-fledged genius. A good-for-nothing? No such thing. Starting out as a genius is the right way to do it. Watch as the protagonist turns a body everyone considers useless into a genius physique, blazing a new trail as he fights monsters, levels up, and rises to the peak.
