"Young man, why are you asleep? Wake up, it's cold here, don't freeze cold!"

Suddenly, an old voice came from Qin Xuan's ears, and immediately after, Qin Xuan opened his eyes.

An old man with gray hair, his face was full of vicissitudes, but his eyes were full of wisdom, he was leaning over slightly, looking at Qin Xuan with a concerned face.

Qin Xuan hurriedly stood up from the back of the reclining chair and said with a smile, "Grandpa, is there something wrong?"

Hearing Qin Xuan's words, the old man shook his head slightly: "Young man, I saw that you fell asleep here, so I woke you up, you will get sick if you sleep here, by the way, young man, which department are you from?"

Hearing the old man's concern, Qin Xuan immediately smiled and said, "Grandpa, you sit, I just feel a little tired, so I'll rest here for a while, hehe, but I'm not a student here, and I haven't gone to college yet!"

The old man glanced at Qin Xuan, then sat down on the row of chairs, and said with a smile: "Young man, you also sit, you said that you haven't gone to college yet, so why are you here, you should be in school now, right?"

Qin Xuan also sat down: "Grandpa, there are some things that I can't say clearly, I also came here to see what the university is like!"

"Hehe, then you're in the right place, young man, are you alone, you didn't come with your family?"

The old man looked around, but saw that there were only two people here, him and Qin Xuan, frowning slightly, and said kindly.

"Hehe, old man, it's just me, by the way, old man, are you a university professor here?"

Qin Xuan looked at the briefcase in the old man's hand and asked with a smile.

"Hehe, it's not, I'm a teacher at Yanhuang University, and I'm here to attend a seminar, and when I see that there's nothing to do, I'll be lazy and come here to walk around!" the old man said with a smile.

"Oh, that's it, grandpa, my name is Qin Xuan, what do you teach in the university?" Qin Xuan was also curious about the identity of the old man, although he had a lot of contact, he had never dealt with a university teacher.

"Hehe, I teach mathematics, my name is Huang Zheng, if you go to college in the future, you can come to my mathematics department, and I will give you the green light!"

The old man saw that Qin Xuan was very sensible, and he liked it very much in his heart, so he joked.

"Hehe, Grandpa Huang, even if I go to college, I will be admitted with my true skills, I won't go through the back door!" Qin Xuan smiled slightly, he naturally knew that the old man was joking with himself, but he also insisted on his own principles.

"Hehe, that's good, as long as you have ambition, I believe you can be admitted to your ideal university!" Hearing Qin Xuan's words, the old man was very relieved and encouraged Qin Xuan.

"Thank you Grandpa Huang, I also believe that I can be admitted to the university I want to go to!" Qin Xuan looked at the old man and said with a smile.

Suddenly, Qin Xuan's eyes froze, because he found that although the old man's face was ruddy, he was faintly pale.

"Grandpa Huang, are you feeling unwell?"

Hearing Qin Xuan's words, Huang Zheng was stunned for a moment, then looked at Qin Xuan, and said a little puzzled: "Yes, I suddenly panicked in the house, so I came out to breathe, by the way, Xiao Xuan, how did you see it?"

"Hehe, Grandpa Huang, I'm a doctor, if you don't mind, then I'll give you a pulse!" Qin Xuan looked at the gradually pale color on the old man's face and said softly.

"Hehe, Xiao Xuan, then you can show me, and I will also see how powerful Xiao Xuan's medical skills are!" Huang Zheng stretched out his hand to roll up his sleeve, and then stretched out his hand in front of Qin Xuan.

Qin Xuan stretched out his hand and put his fingers on Huang Zheng's pulse.

Huang Zheng was slightly stunned when he saw Qin Xuan's troubled appearance, just now he thought that Qin Xuan was joking with him, after all, he saw that Qin Xuan was so young, and he was still a child who didn't go to college, how could he have any medical skills!

When he did this, he just regarded Qin Xuan as a grandson, with such love!

However, seeing that Qin Xuan was taking his pulse seriously, he did not retract his hand, but looked at Qin Xuan seriously, his eyes full of surprise.

After a while, Qin Xuan put down his hand, frowned, and finally looked at the old man and said slowly, "Grandpa Huang, do you have pneumoconiosis?"

Huang Zheng was stunned when he heard this, and looked at Qin Xuan's eyes with incredulity, and finally sighed: "Yes, I only discovered it recently, sometimes it is difficult to breathe, you said that I have not written chalk for many years, how can I get this disease again?"

"Grandpa Huang, this is probably the root of the disease left by you when you were young, and now the environment in the capital is not very good, and the air is also mixed with tiny particles, so now, this disease has broken out!"

Qin Xuan looked at the old man's pale face and explained slowly.

"So that's the case, but I lived to this age to get this disease, it seems that God is taking care of me!" Huang Zheng looked at the turbid sky with his eyes and sighed unusually.

"Hehe, Grandpa Huang, I said I can cure this disease, do you believe me?" Qin Xuan looked at the old man and said with a faint smile on his face.

Huang Zheng was stunned for a moment when he heard Qin Xuan's words, and then turned his gaze to the sky to Qin Xuan's face, looking at Qin Xuan's unusually clear eyes, Huang Zheng was also slightly distracted.

After a long time, Huang Zheng moved his gaze to other places and said softly: "Xiao Xuan, from your eyes, I already believe in you, but I have lived to this age, it is the same for me whether I am sick or not, I can't make trouble for you anymore!"

Hearing the old man's words, Qin Xuan was stunned, and after thinking about it, Qin Xuan knew that the old man was afraid that his medical skills were not perfect, and if he was in trouble with him, then he would have to bear the corresponding legal responsibility.

Qin Xuan smiled slightly and said, "Grandpa Huang, don't worry, I am a miracle doctor, and I will be able to cure your illness soon!"

"Really?" Huang Zheng still didn't believe it, after all, Qin Xuan was too young, and although he liked Qin Xuan very much, he was afraid that he would cause trouble for Qin Xuan, so he naturally didn't want Qin Xuan to treat him.

"Hehe, Grandpa Huang, don't worry, I'll treat you now, I promise to cure your illness immediately!" After Qin Xuan finished speaking, he took out his wooden box and opened it, revealing the silver needles inside.

"Okay, but I'll write a note first, saying that this treatment is voluntary for me, and if anything happens, I will bear the consequences, and it has nothing to do with you. Xiao Xuan, if you agree, give me treatment, if you don't agree, then forget it!"

Huang Zheng looked at Qin Xuan and said seriously.

Seeing the old man's serious appearance, Qin Xuan's heart was also extremely moved, he knew that the old man was caring about himself and defending himself, but he wanted to cure the old man's illness even more.

Seeing Qin Xuan nodding, the old man immediately opened his briefcase, tore out a piece of paper in a notebook, and then picked up a pen and wrote on it that he would bear the unexpected consequences of this treatment.

Seeing that the old man had finished writing, Qin Xuan put away the font, in fact, this font had no effect on him, but in order to reassure the old man, Qin Xuan had to put it in his pocket seriously.

"Grandpa Huang, take off your upper body clothes first, so that I can give you a needle. Qin Xuan looked at the old man and said with a faint smile.

The old man nodded, since he had already promised to let Qin Xuan treat him, and then wrote a note, he would naturally let Qin Xuan arrange it.

Seeing Qin Xuan pricking a needle in his chest, Huang Zheng also felt a slight pain in his chest as if he had been caught by ants.

Qin Xuan was seriously administering the needle, he knew that he was about to return to Linhai and couldn't stay in the capital for long, so he decided to use the Xuan Liquid of Life to cure the old man's body at once.

In the past few days since he came to the capital, Qin Xuan has not let go of the condensation of the Xuan Liquid of Life, so now in his dantian, there are already several drops of the Xuan Liquid of Life suspended.

And he decided that after he went back, he would use these Mysterious Liquids of Life to freshen up his family's bodies, so that his family's bodies would definitely be free from all diseases and would always be in a healthy state, so that Qin Xuan would also be a lot more relieved when he went out to perform the mission.

Slowly guide a drop of the Xuan Liquid of Life out, and then through the silver needle, the liquid of the Xuan of Life is introduced into the lungs of the elderly, as soon as the Xuan Liquid of Life enters the lungs of the elderly, it immediately emits a soft light, and quickly nourishes and washes the lungs of the comer.

After healing the old man's lungs, Qin Xuan guided the remaining Xuan Liquid of Life to the heart, where through blood circulation, the Xuan Liquid of Life would slowly melt into the blood, and would slowly nourish the old man's body.

Seeing Qin Xuan pull out the silver needle, Huang Zheng felt a sense of relaxation in his body, he hadn't felt this way for a long time, this feeling was only felt when he was young!

"Xiao Xuan, is it cured, this feeling is so nostalgic, it reminds me of when I was young, playing with a group of friends, at that time, I was really high-spirited!"

Huang Zheng opened his hands, hugged the air, and said with emotion.

"Grandpa Huang, I think you better put this dress on quickly, otherwise you have to be careful of catching a cold!" Qin Xuan said happily when he saw the old man's intoxicated appearance.

"Hehe, that's true, but my body hasn't been as relaxed as it is now for a long time, Xiao Xuan, I didn't believe in your medical skills just now, Grandpa Huang apologizes to you, you are really a miracle doctor!"

Huang Zheng put on his clothes and said apologetically to Qin Xuan.

"Hehe, Grandpa Huang, don't say that, I was very touched by your concern for me and my maintenance before! Besides, we are meeting for the first time, and it is human nature that you don't believe me!"

Qin Xuan put away the silver needle and put it into the wooden box, and said with a slight smile.

"Hehe, no matter what, Xiao Xuan, you cured my illness, although I don't know how you did it, but your Grandpa Huang owes you a love! If you come to Yanhuang University in the future, come to me at this address, and let your Grandpa Huang thank you well!"

Huang Zheng took out a piece of paper again, wrote down the address where he lived, and handed it to Qin Xuan.
