A warrior killed his master. He repented immediately but the deed was done and he knew that if he was caught, he would be put to death. So he ran away. He reached a remote village that was separated from the rest of the world by a mountain. The murdererdecided to repent for his sin by single handedly cutting a road through the mountain to connect the village with the rest of the world. He worked from dawn to dusk and in four years had made halfway into the mountain. One morning when he was hard at work in the tunnel, a young man called out to him to come out. He was the son of the man who was murdered. He wanted to take revenge.
