Yun Ya withdrew his hand and said indifferently, "Bring your head nurse here." The young nurse was somewhat confused, "Miss, may I ask what’s the matter?" Yun Ya did not answer, but instead sent out a text message. "Yun Ya, what’s going on?" Zhuang Xiyue asked worriedly. Yan Song’s gaze fell on the syringe in the nurse’s hand, could it be... Wei Qing hurried in soon after. Yun Ya pointed at the syringe in the nurse’s hand, "Is this Vitamin C?" Nᴇw ɴovel chaptᴇrs are published on novelꞁire.net Wei Qing walked over, snatched the syringe from the nurse’s hand, pulled out the stopper, and sniffed it carefully, her face immediately changed color. A faint smile played at the corners of Yun Ya’s mouth. Zhuang Xiyue immediately asked, "What’s the matter? Is there something wrong with this medicine?" "It’s not Vitamin C; it’s potassium chloride," Wei Qing said with a very ugly expression. Zhuang Xiyue asked in confusion, "What about potassium chloride?" For someone who knew nothing about medicine, it indeed didn’t make sense what potassium chloride was used for. Yan Song, looking grim, stepped forward and kicked the nurse in the chest, "Speak, who told you to do this?" The nurse was completely baffled and winced in pain from the kick, crying and shaking her head, "I don’t know, it was supposed to be Vitamin C, how did it turn into potassium chloride?" Zhuang Xiyue was hopping mad, "What exactly is going on?" Yan Song glanced at Yun Ya, who was calm, and explained, "Potassium chloride cannot be injected intramuscularly, otherwise, it will result in immediate death." Zhuang Xiyue’s face was filled with horror, "How could this happen?" Wei Qing added, "That’s right. A 10% potassium chloride solution, the concentration can’t exceed 0.3%, or it will cause instant death, and this syringe contains a concentration of at least 0.5%." She used to spend a lot of time in the lab during college, and could tell the concentrations by smell—her classmates even jokingly called her ’dog nose’. Zhuang Xiyue’s face immediately turned cold, and she quickly walked up to the nurse, saying sharply, "We have no grudges against you, tell us, why do you want to harm us?" The nurse, terrified, could only cry, "I don’t know anything..." Zhuang Xiyue sneered, "You don’t know anything? Come on, let’s take this to the dean. This is a serious medical incident, not something you can muddle through by claiming ignorance." With those words, she pulled the nurse towards the door. After taking a few steps, she turned her head to Yan Song, "You stay with Yun Ya. I will go to the dean for an explanation. This hospital is simply too ridiculous." Yun Ya gave Wei Qing a look, and Wei Qing immediately followed. After they left, the ward suddenly became quiet. Yun Ya looked at the tall figure standing beside the bed, and lifting her head, she realized Yan Song’s dark eyes were staring intently at her. With her heart skipping a beat, she said nonchalantly, "Brother Yan, what’s wrong now?" "How did you know that was potassium chloride?" After all, they were all clear liquids, especially to someone not versed in medicine, how could one tell the difference. Yun Ya had already thought of an excuse, "A woman’s intuition." Yan Song’s gaze remained fixed on the top of her head, his voice deep and hoarse, "One day, I will have you tell me yourself." His tone was dominant and imperious, like a huge net, entrapping her firmly within it, unable to move, willingly sinking deeper. Actually, Yun Ya was right; it was indeed her intuition that had saved her life. She hadn’t expected that the medicine would be faulty. If they had been a moment later and she had been injected with potassium chloride, she likely would have died once more on that hospital bed. Thinking this, a chill ran down her spine, and she suddenly threw herself into Yan Song’s arms. He stood by the bed, and she sat on it, resting her cheek against his abdomen, holding him tightly around the waist. "Brother Yan, if I died, would you be sad?" Her voice was like that of a kitten’s, scratching at the depths of his heart, filled with anticipation and cautiousness, softening his heart instantly. Wrapping his arms around her slender shoulders, he felt how thin she was, as if she didn’t even weigh two ounces. "I won’t let you die," he said very calmly, but beneath the calm waters hid currents powerful enough to topple mountains. Yun Ya smiled sweetly, and at the same time, her heart ached. In her previous life, after she died and Brother Yan learned the truth, how heartbroken must he have been? Thinking this, she held him even tighter. Brother Yan, just for you, I would struggle against evil forces, and in this life, never leave your side again. Yan Song gently stroked her soft hair, looking down at her as she curled up obediently in his embrace, a hint of indulgent smile passing through his eyes. The spring light was bright, and the time peaceful. However, at this moment, the office of the dean was anything but serene.
