The Eighth Prince's Troublesome Little One in the Qing Dynasty

...Hong Wang, a little boy from a family of police officers, transmigrates one day into the Qing dynasty as Hongwang, the legitimate youngest son of Kangxi's eighth prince. Raised in the family tradition, even in the Qing dynasty he still has a heart set on protecting the country's long-term peace and stability, and ensuring the people can live and work in peace. "The evidence is conclusive. You've broken the law," the little imperial grandson Hongwang says solemnly. "Guards, take him away."

...Ever since the Eighth Prince had a legitimate son, the Fourth Prince found his younger brother more agreeable. "Lao Ba is doing well. He's learned not to let evildoers off the hook. He's so impartial, even more iron-faced and selfless than I am."

...Ever since the Eighth Prince had a legitimate son, Kangxi looked at his son with even more mixed feelings. "Lao Ba's gone soft in the head. He doesn't know how to balance firmness and flexibility. What happened to that smooth operator he was supposed to be?"

...Ever since the Eighth Prince had a legitimate son, it became harder and harder for him to maintain his image as a gentle, virtuous prince. He had only just won over a subordinate, and the next thing he knew, his beloved son had sent the man to the Dali Temple prison. The Eighth Prince resignedly cleaned up his son's mess while trying to comfort himself. "He's my own flesh and blood. Don't get mad, don't get mad." In the end, he couldn't help wanting to go home and teach his son a lesson.

...The Eighth Princess planted her hands on her hips and stood in his way. "Try saying one harsh word to my son!" The Eighth Prince sighed. His gentle image was falling apart day by day, and there was nothing he could do about his son, who was always getting in his way. All he could do was give up and cultivate an iron-faced, impartial image instead.

...Now that the Great Qing had a fearless little imperial grandson who cared only about justice, anyone Hongwang sent to the Ministry of Justice, the Dali Temple, or the Shuntian Prefecture jail had no choice but to reform obediently and wait out their sentence, no matter their status or rank. Nobody could afford to mess with him. Better for everyone to behave themselves.
