When Shen Chenxing was reborn and returned to be engaged to her sister, she discovered that her sister Shen Congyue, who had also been reborn, was determined to give up her position as crown princess and marry her husband from her previous life, the dandy Qin Lang after the change of heart. Shen Chen Xingxing was destined to enter the palace and become the crown prince. He managed the prince's palace with his memories and abilities from his previous life, assisted Prince Jingshi, and also made plans in advance to crack Qin Lang's invention advantage. Qin Lang coerced Shen Congyue to go to the frontier, trying to use the discovery and marriage to rebel, but in the end his plan failed, everyone betrayed and separated, and Shen Congyue personally avenged him. And Shen Chenxing and Jing Shi joined hands to eventually become an emperor and empress, ushering in a prosperous age. Shen Congyue also suddenly woke up and escaped into Buddhism.
