The Supreme Slacker of the Immortal Cultivation World

A mysterious black cat that escaped from the heavenly realm latches onto a good-for-nothing youth who just wants to lie flat. Together, they use alchemy furnaces for hot pot, fold talismans into paper airplanes, trick the demon cult leader into becoming a devoted fan, and make the twelve immortal sects beg him to be their alliance leader—but all he wants is to go home and pet his cat. — Description from novelcodex.org
