Liu Liuliu's Travels in Time and Space

Introduction to this book The words in the history textbook suddenly came to life, and the person who could save them turned out to be a careless boy who failed the history exam. Liu Liuliu, an ordinary junior high school student, lost control of his life after saving two seriously injured cats on a rainy night. The clever silver-gray skin and the timid fat blue cat Huihui are actually "time defenders" who traveled from the future. Their organization is engaged in a war across time with the "Entropy Shadow Association" who is trying to tamper with history. What's even more bizarre is that Liuliu himself has become their only "key" to repair time and travel through history - his biofield can resonate with the timeline. From then on, his summer vacation homework became: one minute, flashing back to Chang'an on the eve of the Anshi Rebellion, and uncovering a conspiracy against the prosperous Tang Dynasty under the appearance of a group of cats acting strangely; the next minute, he parachuted to the Storm Pavilion where Yue Fei was wronged, and protected the song "All the Rivers Are Red" from being erased from history; the next minute, he personally visited Zheng He's treasure ship on his voyage to the West, correcting the tampered course on the vast sea... Every time you travel, reality only passes for a moment. But every mission is related to the survival of civilization's memory. Behind him, the shadow of the "Entropy Shadow Association" grew thicker. Why are they obsessed with messing with history? What does the phrase "you are only maintaining a cage" mean? Time is calling for help, and history needs to be protected. Can this unexpected "time key" find the answers to all questions in countless "next minutes"?
