Chi Lang transmigrated. He found himself in a third-rate magic academy in the Middle Ages as a third-rate mage—with zero magical aptitude. But he had a good roommate. His roommate was gorgeous. His roommate had a great temper. His roommate helped him escape danger multiple times. His roommate never complained. Chi Lang started to feel like he might have a bit of a crush on his roommate… and then his roommate solved his singlehood problem. Much later, he discovered his roommate might be a terrifyingly powerful figure— One of the demon lords sealed away by the so-called "God of Magic." And Chi Lang was the one who released the seal.
