After the Mad National Preceptor Usurps the Throne, He Becomes the Empress's Slave

(Female-dominant world, men get hurt, heroine gets hurt, male rivals, gender-bender, both pure) Unhinged Imperial Preceptor vs. Cold-Faced Emperor, They Try to Win Each Other Over, Both Transmigrate.

Xie Haitang: I only wanted power and the throne. Why are you treating me like this?

Xiao Zhuyun: Then why did you poison me to death?

Xie Haitang: If I didn't poison you, how could I become emperor?

Xiao Zhuyun: Then you can stop being Imperial Preceptor, too!

The proud and rebellious Imperial Preceptor, arrogant beyond measure, gradually comes to terms with reality and sinks lower step by step.

Xie Haitang finally kills the useless emperor he himself had put on the throne, intending to ascend and use the powerful System to overturn this world where women rule and men are subordinate.

But by going against the original purpose of his mission and disrupting the world's order, he has all his points confiscated by the main System and his golden finger taken away. The only way to survive is to complete a new conquest mission.

His target is none other than Xiao Zhuyun, the deposed emperor he despises from the bottom of his heart and poisoned to death.

Xie Haitang thinks the mission will be a piece of cake, but after time rewinds, Xiao Zhuyun has already become someone else. He, too, is a person from another world who arrived with a mission.

The useless man of the past has become a ruthless emperor with a sharp edge. He is wary of Xie Haitang at every turn, humiliates him in every way, and keeps closing in on him.

Amid their clashes of political strategy and schemes, the ambitious, peerless Imperial Preceptor finally puts away his sharp edges, loses his ambition, and becomes a timid young man.

The cold-faced emperor, always on his guard, gradually lets down his defenses, falls for him, and spoils him utterly, indulging him without limit.
