Yes, I recommend 'The Legend of Little Mortal Cultivation' and 'World of Familiars: My Battle Pet Can Mutate Unlimitedly.' The protagonists of both books were useless, but the pets were very powerful. "The Legend of Little Mortal Cultivation" tells the story of a good-for-nothing cultivator who became an immortal cultivator. The protagonist has a magical pet and a heavenly treasure that charms many beautiful senior sisters and forms a strong team. "World of Familiars: My Battle Pet Can Mutate Unlimited" was about Chu Tian, a descendant of a branch family. He only had the Fire-cloud Fox, which was called a useless battle pet, but he used his own efforts to bring his pet to greater heights and eventually became a powerful immortal cultivator. I hope you like my recommendation. Muah ~
