I Want to Farm Secretly and Surprise Everyone

This is a world of magic and knights, where there is no great power that can split a three-hundred-mile-long river with a single sword! There are no magic or magic skills! There are only splendid magic, a knight training system that has reached its peak, elves who farm and raise flowers, a giant dragon that can produce metal, and a baron who works hard to ride a dragon! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
