I Have Become the Sweetheart of the Yandere Prince, but I Am an Undercover Agent.

(The double-faced future female national master who is determined to be an undercover agent & the God of War Prince who is ruthless on the surface but fragile and love-minded) Ji Qianyao, the future female Imperial Preceptor of Dajing, was mediocre in appearance and good for nothing except refining alchemy. She was looked down upon by all the noble ladies in the capital and looked down upon by all the ministers in the court. What's even worse is that she also got into trouble with Yan Xingjian, the uncertain war god of Dajing. The two of them started to fight each other when they met. They disliked each other and wanted each other's life. Ji Qianyao: "I don't think we have that much hatred, why don't we shake hands and make peace?" Yan Xingjian: "Do you think I will shake hands with a spy and make peace?" Ji Qianyao wondered, when did she reveal her identity? Did he eat the refined elixir and kill the emperor? Are the noble ladies in the capital frightened by endless means? Are all the ministers of the DPRK and China being arrested? Or did he see the fake face he took off? PS: This article is fictitious.
