One Sword Is in the World of Mortals

When the old madman was sober, he told the young man that there was a terrifying tomb in the world and told him not to go there if he was not strong enough. When he was crazy, he said he seemed to remember a 300-year-old master, but he couldn't remember clearly... When the old madman was about to die, he told the young man that there was a woman. If the young man was strong enough, he would know who it was, and asked the young man to bury them together in the future. The young man said: "I remember, master!"
