The male protagonist Lin Yu is an ordinary young man with a carefree personality and a penchant for fun. One day, while wandering around the second-hand market, he bought an old-looking pocket watch for ten yuan. Unexpectedly, this pocket watch is not simple. It is an artifact that can travel through time and space. However, there are no rules for this time travel. It all depends on the mood of the pocket watch.
After returning to modern times, Lin Yu found that his time travel was reported by the media, and he became a madman in the eyes of everyone. His friend Zhang Yu not only didn't believe him, but also laughed at him because he was crazy for wanting to be famous. In order to prove himself, Lin Yu decided to activate the pocket watch to travel again. This time he arrived in the future world. The technology in the future world is ridiculously advanced, and there are flying cars and robots everywhere. As soon as Lin Yu arrived, he was arrested by the robot as an illegal intruder and put into a cell. In the cell, he met Lao Wang, an exiled scientist. Lao Wang told Lin Yu that this future world seemed beautiful, but in fact it was controlled by an evil organization. They used technology to control people's thoughts. Lin Yu decided to fight against the evil organization with Lao Wang. He used the knowledge he learned from modern and ancient times to create weapons with Lao Wang to fight against robots. After a fierce battle, they successfully overthrew the evil organization and saved the future world.
In order to thank Lin Yu, people in the future world gave him a special reward that allowed the pocket watch to travel according to his wishes. After Lin Yu returned to modern times, he went to Zhang Yu with the reward, and Zhang Yu believed him. Afterwards, Lin Yu took Zhang Yu to travel through various eras together, embarking on a series of funny and exciting time and space journeys.
