"What? Are you actually going to stay here and mooch off us?" Old Qin was truly angry now. "I'm penniless, kicked out by the landlord. I wanted to stay at my girlfriend's place for the night, but she was cheating on me. Since you saved me, I have no choice but to stay here," Xiao Nanli said in a flat tone, showing no intention of getting up at all. "What a disaster! Xiaoyue, how many times have I told you not to save people casually? Look, look, you've brought back a real headache," Old Qin scolded his daughter while resolutely picking up the phone and dialing 110. "Hello, is this the police station? There's a loafer in my clinic. He not only refuses to pay for the treatment but also refuses to leave now. Yes, yes, it's the Jishitang on Taoshan Street. Okay, please come quickly." After that, he hung up the phone with a snap, stopped talking to Xiao Nanli, and walked his short and plump body to the clinic entrance, waiting for the police to arrive. "Dad, why did you have to call the police? Can't we talk things out?" Qin Xiaoyue's face turned bright red with anxiety. Xiao Nanli raised his eyebrows. He originally planned to stay here to practice the Profound Medical Canon, enter the Tao through medicine, and by the way, give this father - daughter pair a hand. With the unique skills of his Profound Medical Sect, even passing on one or two of them casually would be enough to bring them honor for a lifetime. But Old Qin just didn't know what was good for him. "Forget it, forget it. People without good fortune can't be enlightened. But this girl is nice. If we're fated to meet again in the future, I'll naturally give her some benefits," Xiao Nanli made up his mind and stood up. However, just as he stood up, two people hurried towards the clinic. One of them was being supported by his companion and let out cries of pain from time to time. "Uncle Qin, please take a look at my dad. His stomach hurts badly. My wife has gone to hail a taxi, but it's hard to get one right now. Please take a look first," a man in his thirties, supporting the patient, rushed into the clinic, shouting as he walked. Xiao Nanli's heart skipped a beat, and he couldn't help but sigh inwardly, "There's a divine will in the dark. It seems I really am fated to this clinic." Old Qin had already helped the young man to help the patient onto the sickbed and urgently asked loudly, "Hu San, old fellow, what's wrong with you?" The old man called Hu San was already gasping for breath in pain and couldn't speak at all. Cold sweat dripped down from his forehead, and his face was deathly pale. Even the doomsday cannon - fodder would seem better. "Hu San, hold on! I'll try giving you a few acupuncture needles," Old Qin quickly took out the acupuncture needles and twirled one into the patient's Zhongwan acupoint, which is the most important acupoint for treating gastrointestinal discomfort. Subsequently, he also inserted needles into several major acupoints such as Xiawan, Guanyuan, Zusanli, and Shangjuxu. However, Hu San was still sweating profusely from the pain, and his face became increasingly pale. "That's strange. No matter what kind of gastrointestinal disease it is, these needles should have some effect," Old Qin murmured softly, sweating on his head as he saw that Hu San showed no signs of improvement. Scratching his head, he was about to insert more needles when a hand reached out from the side and stopped him. It was Xiao Nanli. He stretched out his hand, and three fingers rested on the patient's wrist, taking his pulse. "Hey, hey, don't make trouble here," Old Qin shouted angrily when he saw Xiao Nanli interfering. Xiao Nanli ignored him. After taking the pulse, he reached out and pulled out the needles that Old Qin had inserted one by one. "Hey, what are you doing again? If anything happens to Hu San, it's all on you," Old Qin's face flushed as Xiao Nanli pulled out the needles, and he couldn't help but shout. Xiao Nanli still didn't pay attention to him. With extreme proficiency, he re - inserted the needles in his hand into the patient's Renzhong, Shanzhong, and Neiguan acupoints. Then, with that special technique, he gently twisted the ends of the needles again. To everyone's surprise, the acupuncture needles started to vibrate. Gradually, four thin pink lines appeared on the positions of Hu San's Governor Vessel, Conception Vessel, and Pericardium Meridian. "Ah! Why are there red lines on my dad's body?" Hu San's son exclaimed in fright. "Uncle Qin, who is this person? Is he reliable? Don't mess around if you don't know what you're doing." At this time, Old Qin surprisingly didn't interrupt Xiao Nanli. Instead, he quietly shushed Hu San's son, motioning for him to keep quiet. Just as Hu San's son was about to ask again, he noticed that with the appearance of the pink lines, his father, Hu San, gradually stopped his heart - rending cries of pain, and his face also gradually turned rosy. "Eh? Dad, how do you feel?" Hu San's son quickly asked. "Much better, much better," Hu San was able to speak within minutes, having gone from a state of near - death struggle to being able to talk. "Ah! A divine doctor! A divine doctor!" Hu San's son exclaimed in disbelief. Old Qin's eyes rolled around, and his face showed an uncertain expression. It was hard to tell what he was thinking. After about five minutes, Xiao Nanli pulled out the needles, helped Hu San sit up, and said, "Your heart disease is very serious. You need to get treatment as soon as possible." "Ah? What heart disease? My dad clearly has a stomachache," Hu San's son asked in surprise upon hearing Xiao Nanli's words. "Yeah, it's clearly a stomachache. Why are you bringing up the heart?" Old Qin finally found an opportunity to question Xiao Nanli, sticking his neck out. "To say you're ignorant is an understatement. Haven't you heard that the heart and abdomen are connected? The heart and the small intestine are interior - exteriorly related. Such a simple principle, and you don't even know it. No wonder your clinic has so few patients," Xiao Nanli said unceremoniously, patting Old Qin's chubby shoulder. "Although this patient shows symptoms of a stomachache, it's actually a heart disease. Learn something, Old Qin." Old Qin's face flushed again from what Xiao Nanli said, but he didn't refute. Instead, he asked with a flattering expression, "Then what kind of acupuncture technique was that you used just now?" "The Four - Elephant Acupuncture Method. Have you heard of it?" Xiao Nanli said with a smile. "The Four - the Four - Elephant Acupuncture Method?" Old Qin almost stumbled. But then he started shouting, "You're talking nonsense. The Four - Elephant Acupuncture Method has been lost for over a thousand years. It's just a legend. Aren't you afraid your tongue will get twisted from talking such big talk?"
