He Mistakenly Adopted the Sickly Emperor as His Son-In-Law

[Ancient ideas | Machiavellian strategies | System | Strategies for villains | Yandere | Mutual redemption | Deep sadomasochism] I raised the future emperor as my son-in-law for three years. On the wedding day, I tore up the marriage certificate in front of everyone: "I raised you just for today." As soon as I transformed into the heroine of ancient sadistic novels, the system forced me to take on a suicide mission: I found the future iron-blooded tyrant Xie Jinghan, raised him until he fell in love with me, and then crushed his heart in public. I picked up a young man in a ruined temple who was seriously injured and had amnesia. He tugged at the corner of my clothes and called me "sister" with wet eyes. I named him Ajin, taught him how to read, sent him to the imperial examination, and watched him win three yuan in a row for me. On the day he was paraded in the street, he left behind all the glory in the city, knelt down in the street, and held up all his wealth: "Sister, please marry me." I took the marriage certificate with a smile, and the system rang in my mind: [The sadistic value is 99%! Enough. The wedding ceremony was witnessed by hundreds of officials. I tore up the marriage contract and threw the love pendant he gave me into the brazier: "The play should come to an end. I have raised you for three years——" "Just for today, I will destroy you in front of everyone." With red eyes, he knelt down into the fire and fished out the hot jade pendant with his bare hands. The whole hall was filled with dead silence, and the system cheered: [Mission accomplished! The cruelty value is 100%! I turned around to leave, but my wrist was grabbed tightly. The moment I looked back, my breathing stopped—— All the brokenness in his eyes dissipated instantly, and a cold smile curved at the corner of his lips. "Click." The system in my brain was crushed with his bare hands, and the blue light exploded. He whispered softly in my ear, his words were like a knife: "Sister." "Your mission is over." "Now-" "Time to play my game."
