Lu Chuncan, the daughter of the prime minister of Qi State, was forced to marry to Gongbu, a minority ethnic group in the north, and became the concubine of Crown Prince Yi Qi Langya because her fiancé, General Tantai Liujing of Qi State, was defeated in Langya Mountain. Yi Qi Langya has long been determined to belong, and in order to survive in the cracks, Chun Can endures the humiliation and bears the burden. Unable to endure it, she tried to escape from the marriage, but was caught by Langya. Fearing the consequences of clan rules, she attempted suicide. After the Senate trial ended, Langya bore all the punishment for her.
On the other hand, the released Tantai Liujing was also forced to marry Kampot Princess Yi Qilongke. Because he was unwilling to do so, he defected to the neighboring country of Li, hoping to use his strength to attack Gongbu. Yi Qilongke was beheaded by Qi Guo. After hearing this, Langya wanted to take someone to the robbery site and exchange Lu Chuncan. The relationship between the two originally heated up but then cooled down. After the robbery, Langya fled into Langya Mountain with the spring silkworms, and meandered all the way back to Gonpot.
