Su Chen traveled through time and became a poor scholar. In the imperial examination room, the son of Duke Chen Guogong plagiarized the test papers and was framed for cheating. In a rage, he silently wrote "A Brief History of the Millennium" on the spot. From the fall of the Great Xia Dynasty to the steam revolution and the end of nuclear war, every word was shocking. Prince Zhao Xuan personally investigated the case and found that the history books predicted the coup in the court that day; the powerful minister Chen Guogong wanted to kill people and seize the books to tamper with the future. Lin Qingfeng gave up his fame and followed him to prove his innocence, Liu Rushi exchanged information for Su Chen's promise, and Zhou Zongyue lurked for many years just waiting for the truth. Su Chen, who holds a thousand years in his hand, must use prophecies to avoid the murderous situation, but also be careful not to let history collapse prematurely because of him.
