After Passing Through the Book, I Recruited My Archenemy, the Disabled Prince.

According to unofficial records: During the Battle of Huangshui, Prince Nishizawa was captured and was rewarded by the Emperor Donglin with the second princess as a nun. The prince Gu Jiuchen endured hardships and suffered humiliation. He finally returned to Xize Kingdom, cured his disability, and returned to Donglin, where he beheaded Emperor Donglin and removed all the princess and her other ministers. At this point, the world is unified. —— Song Nanyi accidentally traveled through time and became the heroine in the wild history. On the first day, she got married to the man who chopped off her head in the book. There were lanterns and festoons all around, and servants came to report that Prince Gu Jiuchen had been sent to the bridal chamber. In order to keep her head safely on her neck a year later, Song Nanyi, who had a strong desire to survive, hugged her thigh decisively. She laughed lightly at all the overt and covert attacks and the various ways in which everyone in the harem made things difficult for her. Good food and drink were served, and good words were spoken. I just ask that His Highness the Crown Prince can spare her head after one year. —— One year later When Gu Jiuchen returned to Xize, he responded to his call and was invincible. However, he gave up the chance to dominate the world because of Song Nanyi. Accompany her to bring peace to the world, with a marriage certificate, a phoenix crown and a beautiful robe, and thousands of miles of red makeup. Song Nanyi presented him with mountains and rivers as a gift and Donglin Kingdom as a return gift. Join hands for a lifetime of prosperity. —— Folk rumors say that the second princess is not picky, as long as she is a man Gu Jiuchen: No! She looks good! Rumors also say that the second princess abused Mrs. Gu in every possible way and was inhumane. Gu Jiuchen: That's nonsense! My princess is pure and kind! Rumor has it that the second princess went to Xieguan Qinlou to drink wine. Gu Jiuchen: Bah! Bullshit rumors! Why isn't the name of the building revealed?
