Vũ Khí Hiện Đại Ở Trung Cổ

Lucien, a useless duke's heir, is replaced by a modern transmigrator with a time-space bracelet. He brings modern weapons to the medieval world, shines at the royal hunt, annuls his engagement, defeats 200k barbarians with 10 knights, destroys 30 pirate ships with one destroyer, and hunts beasts with missiles.
