จากอัจฉริยะไร้ค่า สู่ผู้คืนชีพเผ่ามังกร

One hundred years after the extinction of all dragons on earth, Matthew manages to awaken as an SSS-rank Dragon Tamer—only to become a “useless genius,” considering there are no dragons for him to tame. As a result, his girlfriend abandons him; his sworn brothers look down on him; and even his usually amiable mentors cast cold, disdainful glances his way. But what no one knows is that Matthew also awakened a power known as the Dragon Rearing System. Under his care, a fiery-red dragon egg quietly hatches; and now, the legendary Five-Colored Dragons are making their return one by one!
