Dragon Raja: Lu Mingfei Returns from the Demon Realm

After decades battling demons in another world, Lu Mingfei's soul returns to his forgotten homeland—only to discover Earth's hidden war between humans and dragons. Armed with demon-slaying experience and a warrior's instincts, he faces the Dragon King crisis with one question: why use magic when a good sword works just fine? But the academy's carefully constructed supernatural order wasn't prepared for a veteran who treats ancient dragon lords like common loot-dropping mobs.
