Song Guo was quite perceptive when she handed an umbrella to her master, while also pulling Miao Zhu along, who was about to step forward. Ye Yiheng opened the umbrella and gestured to Leng Yu Yan with his hand. Leng Yu Yan placed her hand into his palm, and the two of them walked together toward the house across the street. Seeing the masters walk away, Miao Zhu nudged Song Guo in the waist with her elbow, "You’re quite the slacker, aren’t you? I had an umbrella ready and was about to hold it for my Commandery Princess." Song Guo rubbed his waist and shook his head, "Miao Zhu, you are really a blockhead." He was creating an opportunity for His Highness and the Commandery Princess to be together! Miao Zhu frowned, "Blockhead?" "You’re a knotty elm, slow on the uptake," Song Guo said and ran off along the corridor. "You rotten Song Guo, how dare you insult someone," Miao Zhu chased after him. He ran fast, and she couldn’t catch up; in her urgency, she raised the umbrella in her hand to strike him on the head. Song Guo suddenly stopped, turned around, and with a smile, watched her without ducking. Miao Zhu was taken aback, and due to momentum, she couldn’t pull back her hand or her steps in time. The umbrella struck squarely on Song Guo’s head, and unable to stop herself, her body went straight into Song Guo’s embrace. With a full embrace, Song Guo’s lips curved upward more and more. This was the second time he had held her! Uh, why does this person’s waist feel thicker? Miao Zhu’s face flushed red, this eunuch dared to hold her! Just as she was about to scold him, she heard him say, "Miao Zhu, you’ve been sneaking snacks, haven’t you?" After steadying her figure, Song Guo let go of her and casually took the umbrella from her hands. Miao Zhu pinched the flesh on her waist and belly, "Perhaps I have been eating too much, the Commandery Princess has treated me too well, and I can’t resist my cravings. But no matter how much my Commandery Princess eats, her waist stays slim. Why is mine so thick?" Song Guo forced a smile, "If you continue to gain weight, what will your future husband do if he can’t carry you?" Just then, Mo Chen came over, raised a fist, and showed off the muscles of his arms under his tight clothing, "Miao Zhu, no matter how much you gain, I can still carry you." Not far away, Ruofeng’s voice also came, "I can carry you too, I think Miao Zhu’s figure is quite good, not fat, not thin, just right!" Song Guo didn’t expect Mo Chen and Ruofeng to be so straightforward. His earlier comment was supposed to prompt Miao Zhu to retort, but he didn’t expect to give these two a chance to confess. Miao Zhu laughed exaggeratedly, "I gratefully accept your advice." Mo Chen Ruofeng looked at each other. Could she not detect the hidden meaning in their words? Song Guo shook his head with a laugh; Miao Zhu was clueless to a certain extent, so he could rest assured that she wouldn’t be snatched away by someone anytime soon. At this moment, inside the pharmaceutical room, Leng Yu Yan brought out a series of tools. Seeing the various sizes of glass bottles and the assortment of strangely shaped tools, Ye Yiheng couldn’t help but ask, "What are these for?" Leng Yu Yan sterilized a silver needle, then spoke, "Previously, when Your Highness released poison blood from your fingertip, you were not at Linqing Pavilion. Today, let’s try the tools here." "Using these?" Ye Yiheng pointed to a pile of amazing tools on the long tabletop. "Yes, we’ll put the poison blood in and then analyze to see if we can draw a conclusion." "How do we reach a conclusion?" he was still puzzled. "The poison blood contains different toxins; different toxins will react differently when they come into contact with different reagents. We can use this to determine which toxins are present in Your Highness’s body," she explained. However, these tasks were all being performed and judged by her personally, which means to some extent, it wasn’t clear what toxins were actually present. This was the shortcoming of not having modern instruments. Ye Yiheng asked again, "How do we set up the different reagents?" "Put in the antidote or reagents that would react, and from this, we determine." He extended his hand, "That’s very good." Leng Yu Yan cast her eyes down to feel his pulse, "Your Highness, the toxins in your body have decreased a lot. At the moment, they are relatively dormant. Please, Your Highness, channel your Inner Strength..." It took half an hour just to force the toxins to his fingertips. Leng Yu Yan collected the poison blood into ten glass bottles and then added different reagents to each. Soon, two of the glass bottles reacted, while the remaining eight showed no change. Ye Yiheng leaned closer to take a detailed look, "Can we draw a conclusion now?" Leng Yu Yan furrowed her brows, "The toxins in Your Highness’s body are more complex than I imagined. This time, we have only identified two poisons." He asked, "Which two poisons?" "One is cold poison, and the other is Strychnine, also known as ’Strychnine tree’." "Strychnine?" Ye Yiheng’s handsome eyebrows knitted together. "This poison can cause convulsions, and convulsions can easily be fatal. Moreover, when the poison acts, it can cause reactions in hearing and vision. Your Highness’s eye disease might be provoked by this poison interacting with another," she paused, then continued, "Both of these are deadly toxins, but Your Highness is still very much alive, which indicates that there are other toxins in the body counteracting each other." "I understand that if any one of these poisons were in another person’s body, they would be fatal. But I am still alive because of an excessive amount of toxins in my body." "That’s exactly right," Leng Yu Yan nodded slightly, "Given the current situation, I will still adopt a conservative approach, preparing the Detoxification Pills and then coupling them with the Silver Needle Technique. We will address this from both ends." He also nodded, "Good, let’s do as you say." Leng Yu Yan spoke earnestly, "If Your Highness wishes to completely eradicate them, it would be best for us to investigate and find out who has poisoned you with what." Ye Yiheng pondered for a moment and nodded. Perhaps only when he ascended the throne would he be able to thoroughly clear out who had poisoned him. Just then, another glass bottle reacted, and Leng Yu Yan’s brows tightened. Seeing her anxiety, Ye Yiheng hurriedly asked, "What’s the matter?" "This poison doesn’t belong to our Tiancheng. I added the reagent just to try, not expecting a reaction." At those words, Ye Yiheng’s eyebrows also furrowed, "What kind of poison?" Tiancheng had commerce with the surrounding minor nations, but transactions involving toxins and reagents were forbidden. The poison from neighboring countries had actually infiltrated Tiancheng without being detected at the border, indicating that the person in possession had significant power to evade the government inspection. Leng Yu Yan shook her head slowly, "I am not yet clear about what poison it is, which is also why the reaction of this reagent was slow. But I generally judge that this poison comes from Ximo." Ye Yiheng clenched his fist, saying with a deep voice, "Ximo has much sand and has long been covetous of Tiancheng’s vastness and riches." Who could harbor such malicious intent? Ximo had extended its hand to Tiancheng, harboring the thought of assassinating him from afar. She looked up at him, murmuring, "So many seek Your Highness’s life, any one of these toxins could be lethal in an instant." What suffering had he gone through? No wonder Ye Jiu had said that at the age of fourteen, his life had been in grave danger several times. With this thought, Leng Yu Yan slowly walked up to him and wrapped her arms tightly around his waist. The sudden embrace made Ye Yiheng stiffen, his back tensing instantaneously. "It must have been tough for Your Highness in the past, wasn’t it?" she said, her voice tinged with a trace of sourness at her nose and redness in the corners of her eyes. Ye Yiheng, after a pause, raised his hand to tightly embrace her, "It’s not tough anymore." With her by his side, even the hardest past did not matter! Outside the room, the rain began to ease, and the air grew even more refreshing.
