Upon hearing these words, Wu Liangjun broke out in a cold sweat. Was the Commandery Princess investigating Mrs. Zhang’s death? He didn’t know how his father had explained the situation, and now, what should he do? Leng Yu Yan smiled faintly, "Since I have reminded you, it’s Doctor Wu’s turn to speak." Wu Liangjun caught a glimpse of two men’s shadows on the floor, their bearing seemed to exude an imposing aura. But their faces were not visible, only their shadows reflected on the ground indicated that they were standing not far away. If he said something unfavorable, would these two men immediately kill him? Thinking this, Wu Liangjun awkwardly smiled, "Commandery Princess, what are you talking about? As doctors, my father and I must fulfill our duties to the Lady and to you." "So that means you don’t want to talk," Leng Yu Yan asked slowly, "Lai Manting’s facial patches were torn off, and you and your father cheated her out of 5,000 taels of silver. The crime you’ve concocted is not minor. Do you need me to say a word on your behalf to the Capital Mayor Mansion?" Wu Liangjun panicked, "The peeling of Lai Manting’s face is a result of her own doing. Commandery Princess, when you were ten, your appearance and physique underwent drastic changes due to Mrs. Feng and Lai Manting’s actions. It was Lai Manting, who has been jealous of your beauty since childhood, conspired with Mrs. Feng to ruin your appearance and body." "But the poison was prepared by you and your father." "We, father and son, were also forced by Mrs. Feng and her daughter. This matter of making a living, indeed, we were at our wits’ end!" Wu Liangjun covered his face, pretending to cry, "Commandery Princess is beautiful and kind-hearted, surely you can understand our predicament!" "Hehehe, predicament?" Leng Yu Yan sneered, "I mentioned earlier that you are not young anymore, well into your thirties. Six years ago, before my mother passed away, all the prescriptions were from you and your father. I’m sure you remember that very clearly." Wu Liangjun’s back was covered in sweat. If he admitted even a single word now, he feared he might not escape without serious consequences. If Leng Yu Yan found out that Mrs. Zhang’s death was also due to the poison prescribed by them, father and son, they would certainly meet a terrible fate. Even if they tried to place all the blame on Mrs. Feng, they wouldn’t be able to escape their involvement. With Leng Yu Yan’s current status, taking their lives would be effortless. Upon this thought, Wu Liangjun knelt on the ground and kowtowed, "Commandery Princess, the prescriptions we gave to your mother indeed came from us, but I assure you there were no mistakes in them. Your mother’s death has nothing to do with us!" "Even under severe torture, I will never admit to something I did not do!" Wu Liangjun kowtowed again. "Don’t worry, I won’t torture you," Leng Yu Yan stood up, "It seems that Doctor Xiao Wu has a rather poor memory. I have plenty of time; why don’t you reflect on it a little more?" With that, Leng Yu Yan walked away. After a few steps, she turned back and said to Xiaoshan, "Stick to the old one speaking the truth. Make sure to fill the old one’s meal to eighty percent." Xiaoshan didn’t understand but took the Commandery Princess’s word for it that she had her reasons. "Yes, Commandery Princess!" Leng Yu Yan hummed in acknowledgment and then exited the dungeon. Once outside, Xiaoshan finally asked, "Commandery Princess, we haven’t interrogated the old one yet. Did you say that because..." Ye Yiheng and Li Yuyue followed at a leisurely pace, with Li Yuyue explaining, "Yan’er is waging psychological warfare. By breaking down Xiao Wu first, no matter what Old Wu argues later, Xiao Wu will become the point of breakthrough." Xiaoshan nodded continuously, "I understand now. This is why we separated the Wu father and son." "It’s getting late; you should rest early," Leng Yu Yan instructed, "Have someone keep an eye on Wu Liangjun; don’t let him sleep too comfortably." Xiaoshan agreed and left to carry out the order. Li Yuyue asked, "Yan’er, since the Wu father and son are definitely the ones who prepared the poison for Mrs. Feng, why bother interrogating them?" In his view, Mrs. Zhang’s death, Yan’er’s biological mother, was most likely caused by eating food or medicinal soup containing poison. Why go through the trouble of interrogating Mrs. Feng and her daughter after directly killing Ms. Wu and her son to take revenge? Leng Yu Yan said, "Although I suspect Mrs. Feng of plotting against my mother, I have no tangible evidence. Words alone are not proof, that’s one thing. Secondly, I always feel that there’s more to my mother’s death, a hidden truth that I’ve yet to discover. That’s why I’m proceeding this way." It was then that Ye Yiheng spoke up, "Yanyan, do you suspect that your mother’s death is related to the incident seventeen years ago?" "Yes, that’s why I’m taking my time interrogating the father and son of the Wu family," Leng Yu Yan replied, taking a step forward. Li Yuyue nodded, and the group walked toward their residence. As they walked through the courtyard, they saw Ye Jiu waving his hand. "Princely Heir, I’ve cooked some night snacks. Come back to your room and have a bite." "Did you cook them especially for me?" Li Yuyue pointed at himself. "Naturally!" Ye Jiu laughed. Leng Yu Yan said, "Big brother, I won’t fight you for it. Go ahead and eat." Ye Yiheng also said, "I ate enough at Prince Xian’s mansion, and I really can’t eat another bite of Ah Ju’s night snacks." Ye Jiu’s laugh became even more exaggerated, "Sixth Brother and Ah Yan really understand me. Tonight’s snacks were only cooked for Princely Heir and me, I’ll cook for Sixth Brother and Ah Yan next time." Ye Yiheng waved his hand, "No need, really." As he spoke, he patted Li Yuyue on the shoulder, "Big uncle is really lucky!" Li Yuyue managed a somewhat strained smile, "Since it’s night snacks, let’s eat together. I’ll eat less." Ye Yiheng shook his head, taking Leng Yu Yan’s hand and moving forward, "We’re going to rest." On the way, Leng Yu Yan asked in a low voice, "By the look on your face, are you very unwilling to eat what Ah Ju cooks?" "What she cooks is inedible," Ye Yiheng said bluntly. "No way? Then my big brother..." Leng Yu Yan looked back, her gaze toward Li Yuyue filled with pity. "Your big brother chose Ah Ju, so naturally, he should respect his choice," Ye Yiheng said softly with a low chuckle, "Since they’ve decided to be together, they should be given more time to get along." Leng Yu Yan watched as Ye Jiu insisted on dragging Li Yuyue into the courtyard and murmured, "Big brother is quite pitiful too." Ye Yiheng caught the implication, "What do you mean by ’quite pitiful’ as well?" Leng Yu Yan turned back, "Your Highness is pitiful, you were irritated by the Seventh Prince today, weren’t you?" "Did Ah Ju tell you that?" "Yes!" She nodded, "Your Highness, I really don’t look down on you. I will always be by your side!" Ye Yiheng pinched her hand and looked deeply into her eyes, "When you talked to me about our partnership, weren’t you hoping I would fail? This would suit you just fine. If you’re content, why come and console me?" The moon was bright, but it could not reveal the expression in her eyes. All he heard was her saying, "Your Highness, the past is the past. After experiencing so much together, we are no longer simply partners..." "If it’s not simply partners, what is it?" he asked. "Now we are betrothed, and after marriage, we will be husband and wife. Since we are to be husband and wife, we are one, sharing both honor and disgrace," Leng Yu Yan said earnestly, looking up, "I won’t allow others to gossip about Your Highness’s private affairs, nor will I allow anyone to slander my future husband!"
