Little Sizhi of the Tang Dynasty: Bro Bro, I Have a System!

In doing so, she binds him to the [System for the All-Round Protection of the Little Princess of Jinyang]. A wall connects two cities, and one bowl of instant noodles leaves His Majesty Li Er craving a taste. For the sake of little Sizi's plea, “I don't want my mother,” Yun Yi shoulders his medicine kit and sets foot in the Great Tang for the first time.
