The heroine, who has always admired Xin Qiji, refuses to have a boyfriend in real life. She is extremely depressed because her family urges her to get married, and she accidentally passes away his wife Fan Ruyu in front of his grave. Although the male god was very good, she could not accept the ancient living system. She left a letter and decided to return to modern times, but she could not find a way to return to modern times.
She discovered that Fan Ruyu's soul existed in the same body as hers, and gradually adapted to ancient life, giving up the idea of returning to modern times. In daily interactions, she also saw the painful and struggling side of Xin Qiji, so she hinted to Xin Qiji that only by usurping power could the Northern Expedition be successful. Unexpectedly, her words would plunge Xin Qiji into even more pain. She had to try her best to divert Xin Qiji's attention and relieve his depression, and their relationship also experienced ups and downs.
The heroine, who has been avoiding intimacy, finally confesses her love to Xin Qiji on Dragon Boat Festival night, but travels back to modern times without warning. Only then did she realize that the letter she left had made Xin Qiji's soul wait for eight hundred years, and the oath she made through the mouth of Ruyu also came true. No matter what time and space Xin Qiji flashed to with his soul power, the heroine would be transported, and as long as the heroine silently recited Xin Qiji's name in her heart, he would come to her immediately.
During the Spring Festival, the heroine takes Xin Qiji home to pretend to be her boyfriend, and unexpectedly convinces her parents, solving the heroine's troubles. But by mistake, the two travel back to the Southern Song Dynasty together, and overcome all difficulties to complete the Northern Expedition. After Xin Qiji completed his obsession, his soul disappeared, and the heroine, who was in pain, also met her lover.
Intention: History and today can go in both directions.
