[Ancient proverbs + palace fighting tactics + no time travel + pure love + big heroine + HE]
Le Yi'er, a gangster, is a master of poisonous skills. He hates evil as much as he hates his enemies. He is a chivalrous and righteous person who is free and unrestrained.
During an operation to rescue a girl, she ran into Nangong Xuan, a yandere prince who traveled around the world hiding his identity!
The prince couldn't stand Le Yi'er's arbitrary execution of human lives, while Le Yi'er thought the prince was too simple and naive.
Le Yi'er accidentally discovered that the frail prince was not born frail, but was poisoned.
The two went through hardships in order to detoxify. In the process, they went from hating each other and being wary of each other, to understanding, trusting and loving each other...
Who poisoned Nangong Xuan? Will Nangong Xuan, who has been sick for twenty years, give up? What kind of palace battle will the two get involved in?
