How Did I Become a Sadistic Heroine?

[Trying to lie down but forced to fight against the pharmacist] × [The sinister, suspicious and self-defeating prince] Since that day when he personally captured his princess from fleeing her marriage, Meng Yaocen always felt that his wife Xie Chen seemed to be a different person. The daughter of the prime minister, who used to be dignified but always showed disdain for herself, suddenly became seemingly cautious, but her actions were full of recklessness. He didn't believe in the magic of changing minds and souls. This behavior must be some kind of strategy discussed between Xie Chen and her prince, who was still in love. It is better not to have a person beside you who harbors alien intentions... Meng Yaocen deliberately exposed the general's secret report in front of Xie Chen, and sure enough, within half a day, the secret report disappeared under his nose. Humph, clumsy means. Meng Yaocen immediately led people to surround Xie Chen, hoping to execute her on the spot for the crime. Who would have thought that this man's sophistry seemed so weird, and he couldn't find a reliable reason. Xie Chen surrendered in front of the room full of guards holding swords. He almost burst into tears. He hurriedly explained: "I'm sorry, I thought no one wanted it, so I used it as toilet paper! Don't kill me!!" Meng Yaocen took the secret report filled with chemical formulas and left with a dark face. This time it was just a fluke, sooner or later he would expose her. Late one night, Meng Yaocen was lying on the bed and smelled a pungent smell on the tip of his nose. He immediately covered his mouth and nose. As expected, the message came from the inner palace of his Crown Princess. It would be too naive to just use poisoning to kill him. This time she could not escape the death penalty. Meng Yaocen did not want to have long nights and dreams again, so he planned to kill his wife with his own hands. But before she even got close to Xie Chen, Meng Yaocen's eyes hurt from the stronger smell of sulfur dioxide all over her body. Xie Chen apologized and said to Meng Yaocen, who was still retching: "Your Highness, do you believe me when I say I didn't mean it?" Xie Chen: Who knows my family? I wanted to make an antifungal agent, but accidentally let the sulfur dioxide leak out. Now the prince seems to have a big problem with me! What to do! Meng Yaocen scanned the people in front of him from top to bottom, squinted his eyes and left. It was also late at night, and Meng Yaocen was reviewing official documents by candlelight, when a bowl of red dates, taro balls and ginger tea was placed in his hand. The attendant said that the Crown Princess made it specially for him. Meng Yaocen stared at the bowl of spoons and carefully recalled Xie Chen's past departures. He had to admit the fact: his princess was no longer the same princess as before. And if this person doesn't want his life now, what does he want? He glanced at the note written with a brush under the bowl of spoon: Your Highness is really sorry, I really didn't mean it. I will be more careful in the future and put your safety first! Huh, how brave you are! Purpose: Learn mathematics, physics and chemistry well
