"Since you've already discovered it, there's no point in hiding it anymore. I'll just tell you the truth. Because of the daily incense burning tradition in Fengyi Palace, little did they know that I had already added a specially made deadly poison to the incense, especially for those who frequently take strong medications, it can hasten death." A cold smile bloomed on her face, a smile that was nonchalant yet carried an extremely obvious mockery: "Now, Yu Qianqian is probably on the verge of death, isn't she?"

As early as when Yu Qianqian left the palace, Su Ruan disguised herself and mingled among the maids of Fengyi Palace. In the end, she entered the palace with Yu Qianqian without anyone noticing. Then, taking advantage of the close relationship between the two countries in the previous dynasty, she carefully set a trap and secretly learned all about Yu Qianqian's whereabouts, as well as her habits of eating, drinking, and living. However, she did not expect that Mu Beichen had already discovered all of this, but for some reason, he was unwilling to take action to stop her, which gave her the opportunity to make her move.

Having heard everything with his own ears, Mu Beichen could no longer suppress his anger and roared, "Su Ruan! How dare you poison her! Today I will kill you to pay for her life!"

In a fit of rage, he grabbed Su Ruan by the neck with his right hand and lifted her into the air, his eyes devoid of any pity. Only when he saw that her face was flushed red and she was almost strangled to death did he forcefully throw her to the ground.

This was the first time he had ever been so ruthless towards a woman, specifically Su Ruan. Although he had never had any romantic feelings for her, he always had to give in whenever she acted coquettishly or played the victim.

But for Su Ruan, Mu Beichen's drastic change was entirely within her expectations. Ever since she learned of Yu Qianqian's existence, she knew this day would come. Even though she had anticipated everything, she was still somewhat unwilling to accept that this was happening to her.

"Mu Beichen, I've noticed you're getting dumber and dumber. Don't you think about it? If Yu Qianqian knew that you saw through everything long ago, yet still allowed me, your mortal enemy, to poison her, do you think she would still trust you?" Su Ruan's every expression was tinged with a smile, and she deliberately spoke slowly and deliberately.

"Mu Beichen, you always pride yourself on being meticulous, but do you know what women hate most?"

"I'm telling you, that's deception!"

Mu Beichen's heart trembled slightly. He stared blankly at the light before him, remaining rooted to the spot without uttering a word.

At this point, Su Ruan became more and more excited as she spoke: "So the thing you should do most now is not how to deal with me, but... try your best to deal with Yu Qianqian, this major threat. But don't worry, since we are now in the same boat, I will do my best to help you."

At this point, the darkness on Mu Beichen's face deepened, and he pressed his hand against her throat with extreme rage, causing every word he uttered to be imbued with fierce murderous intent.

"Su Ruan, don't expect me to be lenient with you this time. If you dare to endanger Yu Qianqian in the slightest, I will make you pay double!"

"I'll give you one last piece of advice: if you don't want to die a horrible death, hand over the antidote to me right now!"

Suddenly thinking of Yu Qianqian's situation, a sharp pain surged in my heart, like a tidal wave crashing over me.

"Hmph! Even if I had the antidote, I wouldn't give it to you!" Su Ruan and Mu Beichen locked eyes, both equally furious: "That bitch Yu Qianqian caused our country to be destroyed and our family to perish, and she shamelessly interfered, stealing the one I love. I... I wish she were dead right now!"
