In a bustling metropolis, there is a museum like a big box. In the process of protecting a national treasure, young security guard Lin Changan discovered that as long as he touched an ancient object, he could "swoosh" back to the era when the treasure was just born. He saw how hardworking craftsmen hammered goldware, and heard how majestic generals guarded the frontier. Lin Changan used this magical ability to expose the lies of the bad treasure appraiser in modern times and save the forgotten historical truth in ancient times. He is like a little hero of time and space, taking us through five thousand years of magical stories, and finally became the most amazing guardian of cultural relics in the world.
