Once upon a time, there was a riddle novel that was actually a very interesting story. The protagonist of the story was a riddle master named Dragon. His unique observation ability allowed him to find the experiment in the riddle at any time. One day, he met a riddle artist named Sai, who made a strange request to him: He needed Sai to write a post-match poem for a riddle novel that included the dialogue before and after the game. Dragon thought for a long time, wondering if this was a strange request, until one day he found the conversation before and after the game, so he immediately began to tell the story. After listening to his narration, Sai appreciated his observation ability and eloquence, and praised his post-match poem. Sai was also very surprised by his talent and gave him a very generous bonus. The Dragon was very excited and used the prize money to pay for his riddles. He also asked Sai to introduce him to some new knowledge in riddles and let them start learning riddles together. The story of the riddle was a very interesting journey. The dragon learned a lot of new knowledge during the journey and began to explore the depths of the riddle together.
