He heard of a an old swordsman in the north and the warrior went there to challenge him, when he reached the swordsman house he issued challenges and then insults, drawing the attention of a crowd. But no one came out. Tired he went away. Afterwards, the door of the house opened and the old swordsman came out to enjoy his afternoon walk. The people asked him why he did not answer the warrior and he simply smiled and said, ” I did not hear him”.
