There is an old legend about a lonely night, a young woman was walking alone in the garden when she suddenly heard a deep sigh. She curiously approached the source of the sound and found an unfamiliar man lying on the ground, breathing weakly. The woman was scared and didn't know what to do. However, the voice sounded again. This time, the voice was even lower. The woman couldn't help but feel curious. She approached the man and found that he was holding a sword in his hand. The woman was terrified and ran away. The sound of the sword echoed in the garden along with her scream. The woman ran to the depths of the garden and found a bottomless cave. She didn't dare to go in, but she heard the voice. It seemed to be calling out to her. The woman decided to take the risk and enter the cave. She passed through the dark cave and finally came to a mysterious room. There was an old bed in the middle of the room, on which lay a white-haired old man. The woman didn't know what to do. She felt fear. However, the old man suddenly opened his eyes and looked at the woman.
