The story begins with an "intelligence test". Lin Jinyou accidentally enters the capital and gets involved in the power struggle in the imperial court. From first becoming an official to entering the core of internal affairs, he continued to break through traps with his unique humor and wisdom, and met like-minded people such as Shen Fengsheng and Zhao Wuyu. The four major forces (the prince, the harem, the powerful ministers, and the eunuchs) take turns to come on stage, with constant laughter but dangers. In the end, Lin Jinyou, amidst the turbulent changes in the palace, turned danger into safety step by step, completed his own growth, achieved a reversal of power, and wrote a compact and interesting new chapter of the palace.
