When He Xizhao first became the study companion of the deposed crown prince, everyone gloated, openly or secretly mocking him for boarding a sinking ship. Sure enough, the deposed prince lived up to expectations—utterly dispirited and unambitious, earning everyone’s disdainful sighs. The study companions from other palaces waited to laugh at He Xizhao, but to their surprise, though the deposed prince committed all manner of absurdities, he guarded his little companion fiercely. He declared, "Mess with me if you dare, but try laying a finger on my precious Xizhao!" To this end, he beat up princes from every palace, drove away imperial tutors, defied the emperor countless times, and did everything reckless under the sun. And then... The deposed prince continued to dominate the palace with his sweet, soft-spoken little companion by his side, while the other study companions—bearing the consequences meant for their own princes—glanced bitterly at their spineless masters and sighed deeply. Yet who could have known that this deposed prince, who slept through lessons and dashed wild after class, would study by candlelight late into the night, covering mathematics, science, classics, history, agriculture, commerce, taxes, criminal law, and more... His tutor? None other than his seemingly gentle, rabbit-like companion, who had long shed his meek disguise to reveal the cunning tail of a fox.
