赵高
On the other hand, Gao Yao is separated from Xiaochuan and sent to the palace, where he is forcefully castrated and becomes a eunuch. After enduring humiliation and bullying, he wins the favour of the emperor through his excellent culinary skills and becomes a high-ranking official. He is renamed to "Zhao Gao" and starts abusing his authority by seeking vengeance on those he perceived to be responsible for his plight. Zhao Gao is gradually corrupted by power and turns against his old buddy Xiaochuan, whom he sees as a threat to his plans for dominating the Qin Empire.
