Modern woman Luo Yunqing unexpectedly transmigrated into a book, becoming the consort of Prince Chen, Xiao Chengjin. In the original novel, Xiao Chengjin had a woman he loved and, disliking Luo Yunqing's original crude and unseemly self, neglected her after marriage. Liu Yanran, deeply favored by Xiao Chengjin, also secretly plotted against Luo Yunqing. Thus, Luo Yunqing found herself in a dangerous situation immediately after transmigration. However, possessing a 'God's eye view,' Luo Yunqing knew Xiao Chengjin's difficulties. So, she played her role while also exposing the 'green tea' concubine and clearing her name from being a 'straw bag' amidst Liu Yanran's troubles. By coincidence, she met He Sheng, a fellow transmigrator from her hometown. She learned that the key to returning to reality lay in the imperial ancestral temple, which could only be opened when a crown prince was officially appointed. Therefore, Luo Yunqing decided to help Xiao Chengjin contend for the throne. Facing overt and covert schemes from rival Xiao Chengxu, Luo Yunqing had to use her modern knowledge to fight back, ultimately successfully helping Xiao Chengjin ascend to the throne.
