Confused Spirit Master

He didn't know how long he slept. He got up from the ground. The ground was wet. He looked around. The fog was very thick. The place where he was was a wetland, surrounded by water. There was a small black shadow on the water, moving like a small boat, and there was a person on the boat. After a while, the black spot came to him. It was indeed a small boat. The person on the boat was a kind old man with white beard and hair, wearing a raincoat. He wanted to ask the old man some questions, such as where is this place and who are you, but before he could ask, the old man said: "Get on the boat." He got on the boat in confusion, and the old man asked again: "People there?" He scratched his head and shook his head. The old man smiled, "Forgot? Never mind. This is all stagnant water, and there is no wind. It's really tiring to rock the boat." The old man wiped his sweat. "Where is this?" He asked the question he wanted to ask the most. "Special place." "Who are you?" "The one who rocks the boat." The old man suddenly pointed into the distance, "The answer is there." He looked in the direction pointed by the old man's finger, and suddenly he felt that the fog was not so thick. What came into view was a hill with a palace on it, which looked eerie in the fog. "The answer, do you want me to go there?" He asked. The old man shook his head and smiled: "How ironic. I am so obsessed that I came here, but I forgot that I wanted to know." "Go back and find what you want." In this way, he came to the world again. For what?
