Manga The Strongest Wizard Becomes A Countryside Guardsman After Taking An Arrow To The Knee

Legends tell of the powerful wizard Alfred, who, during one of his heroic adventures, managed to outwit and become the master of the Demon Lord, but was seriously wounded in the knee by an arrow.
Despite this injury, Alfred did not lose his strength and status, but he decided to temporarily retire to rest. But people had other plans for him. Some needed him to lead a detachment of knights, others invited him to the guild, and still others wanted him to destroy the dragon.
Annoyed by annoying people, Alfred went to a secret village, which only an extremely narrow circle of people knew about, in order to recover in peace and quiet. Here he helped local residents solve minor economic problems, such as attacks by wild animals or natural disasters, in order to receive food in return.
