After intertwining with the princess, my son killed his way through the court and proclaimed himself emperor

Ren Jingxing transmigrated into the body of a down-and-out prince from a noble house, only to find himself swapping bodies with the princess from the very start. According to the *Empress Development Record*, the prince and princess exchange souls every ten days, and Ren Jingxing must help the princess ascend the throne. As a result, every ten days, the temperaments of the two shift dramatically. When Ren Jingxing inhabits the princess’s body, he doesn’t tolerate any disrespect. When the nanny from the Clothes Bureau dares to humiliate the princess, he strikes back directly. When a concubine schemes against her, he deals with it head-on. Even the nobles of the Tianhuang clan are not spared from his sharp tongue. The palace is thrown into chaos—why has the once-obedient princess become so fierce? When the princess takes on Ren Jingxing’s identity, she declares, "My son has the look of a top scholar!" Soon enough, the prince ranks first in the imperial exams. Rumors are proven wrong—the so-called dandy prince is actually the most talented man in the capital. Years later, Wei Xinyan ascends the throne as emperor, and Ren Jingxing becomes the most powerful minister in the land. One day, the empress sits beside him, her eyes filled with resentment: "Brother Prince, these thousands of miles of land may belong to you, but this harem must remain under my control."
