I'm Pretending to Be a Loser, but I'm Actually the God of Dharma

Others rely on talent for cultivation, but Lin En relies on "sleep" for cultivation. In Erathia, where magic is declining, he is the famous "sleepy guy" of Gray Tower Academy, who cannot even learn the simplest glimmer arrow. Until he was cleaning, he accidentally awakened a broken book claiming to be "Lord Morpheus". In the book lives a palm-sized cute demon pet that looks like a black cat but has bat wings. He has a proud temper and an arrogant tone, but he is knowledgeable. Under the guidance of its poisonous tongue, Lin En became enlightened overnight. However, if you want this "uncle" to regain his strength, the price will be a massive amount of magic stones - apply through normal channels? There are no doors. So in this fantasy magical continent, a campus adventure drama starring "Sleepy Man" was quietly staged, and he gradually grew into a great mage.
