Tang Xiaotang is a third-grade student at Zhonghua Primary School. He fell in love with Journey to the West from the first time he heard his mother read it. There are various versions of "Journey to the West" in his bedroom, from comic strips to the original novel. He still couldn't understand the original ancient Chinese novel, so he held a vernacular version of "Journey to the West" all day long and told it to his classmates. My deskmate Zhuzhu loves listening to Xiao Tang telling stories from Journey to the West, and she never seems to get tired of hearing them. Xiao Tang also particularly likes historical stories and geography. His biggest dream is to re-walk the path Monk Tang took to obtain scriptures, experience the stories in "Journey to the West", see the people and things of that dynasty, and see the mountains, rivers, and desert rocks at that time. One morning, Xiao Tang found a reading pen in his desk. This reading pen was called Dian Bao. It could talk and use magic. It actually helped Xiao Tang realize his dream and took him and Zhu Zhu to experience the world of "Journey to the West". Who did Xiao Tang and Zhu Zhu meet in "Journey to the West", and what happened?
