"The rivers and lakes are sinister! Now, I am old. Nangong Yuhan is not deeply involved in the world, I am afraid that even if she can learn everything I have learned in my life in the future, she will not be able to protect herself. So, I want to take you under my door as well. In this way, firstly, you can carry forward my medical skills, and secondly, even if I am no longer there in the future, you can take care of Yuhan for me, so that she will not be bullied. Nangong Hong said to Shangguan Feixue.

"I see. Shangguan Feixue nodded.

"So, do you agree?" Nangong Yuhan asked.

"Nope. Shangguan Feixue still shook her head and said: "First of all, you and I both know that the poison in my body has invaded the five internal organs, even if you can have a way to prevent it from continuing to spread, but it is almost impossible to get rid of it. Besides, as long as you insist on not treating others, I will not agree. ”

Regarding the poison on Shangguan Feixue's body, Nangong Hong did not deny Shangguan Feixue's statement.

"There is a cold pool in the Medicine King Valley, as long as you can soak in the pool for one day a month, plus take my Yuqing Pill regularly, you can completely maintain the status quo for twenty years. In these twenty years, with your qualifications, who knows if there will be a way to remove the poison from the body. Nangong Hong said to Shangguan Feixue.

"There is such a place in this world!" Shangguan Feixue had never heard of such a place in this valley, and couldn't help but sigh.

"In order not to attract the attention of the villains, I have never told anyone about this cold pool. Nangong Hong continued: "As for the matter of re-treating the world, I promised the Immortal Dharma King, as long as I, Nangong Hong, live, my Nangong Gate will never pay attention to the affairs of the rivers and lakes, let alone treat the people who were injured by the poison gate." Words must be believed, deeds must be fruitful, this is the foundation of a person's life. Nangong Hong said lightly.

"Grandpa, Brother Shangguan learns your medical skills, and if you don't become your apprentice, you won't be counted as a member of our Nangong family, so you don't have to abide by your original oath!" Nangong Yuhan proposed to Nangong Hong.

"How can this be ....." Nangong Hong just shook his head a few times, looked at Nangong Yuhan again, and suddenly patted his forehead.

"That's right! I can't take Shangguan Feixue as an apprentice. Nangong Hong hurriedly said: "If you become my apprentice, won't Yuhan have to call you uncle, that's not good." ”

Nangong Hong thought for a moment, nodded and said: "According to what Yuhan said, you can follow me to learn medical skills, but you will not be my apprentice, so that you don't have to keep the promise I made at the beginning, but you must promise me that you will always protect my granddaughter." ”

"That's fine. Shangguan Feixue nodded and agreed.

"Since you agreed, then from today onwards, I will officially teach you the way of medicine. Nangong Hong said to Shangguan Feixue with a smile.

"Thank you, senior!" Shangguan Feixue saluted Nangong Hong and said.

In this way, with Nangong Hong's careful teaching, Shangguan Feixue's medical skills have been advancing rapidly, and they have made rapid progress.

In the blink of an eye, Shangguan Feixue has been in the Medicine King Valley for nearly a year, and in this year, Shangguan Feixue has read all of Nangong Hong's medical books, and under Nangong Hong's careful guidance, there is a great trend of being green and blue.

On this day, Shangguan Feixue was looking through the books in Nangong Hong's room. Without comment, I saw a roll of bamboo slips wrapped in sheepskin. Shangguan Feixue once saw that the content recorded on this bamboo slip was just some ordinary pharmacology and medical prescriptions, and there was nothing special about it.

"Senior, your collection of books here should be very valuable, but I don't see anything special about this book. Shangguan Feixue asked Nangong Hong puzzled.

"You said this bamboo slip. Nangong Hong looked at the bamboo slip in Shangguan Feixue's hand, shook his head, and said, "This is what my ancestor handed down. When my master passed on my medical skills, he just said that this scroll was very important, and he didn't know why this scroll was important, maybe it was a kind of inheritance. ”

After Nangong Hong finished speaking, seeing that Shangguan Feixue was still unwilling to flip through the scroll, he continued: "I have carefully studied the content of this bamboo slip, there is nothing special at all, and you don't have to put your mind on it. ”

"Oh, got it. Although Shangguan Feixue promised so, he was still holding a bamboo slip in his hand, and he opened it to look at it with curiosity.

"This bamboo slip has been too long, and if it weren't for the sheepskin behind it, it might have fallen apart long ago. Shangguan Feixue looked at the scroll and said.

While he was talking, there was a thread in the middle of the bamboo slip that was used to hold the bamboo slip in place, and it was broken.

"Oh no, the line is broken. Shangguan Feixue said as she raised her head and looked at Nangong Hong.

"It's been too long, just wear it again. Nangong Hong said to Shangguan Feixue.

"Got it. Shangguan Feixue agreed, while carefully peeling off the sheepskin, intending to wear the bamboo slips again.

"How can there be words here?" Shangguan Feixue couldn't help but be shocked when she saw a few words on the exposed sheepskin, and blurted out.

"What?" Hearing Shangguan Feixue say this, Nangong Hong hurried over.

Looking at the two big characters "Neijing" written in seal script on the sheepskin, Nangong Hong and Shangguan Feixue glanced at each other in unison, with an unbelievable look on their faces.

"Neijing!" Shangguan Feixue and Nangong Hong said in unison.

"There really is such a strange book in the world! I didn't expect it to be hidden in me all the time!" Nangong Hong laughed excitedly.

Shangguan Feixue also knows from the records of various classics: according to legend, this "Neijing" is written by the medical ancestor Bian Que, which can heal people's internal organs and have the effect of reviving the dead, but after Qin Shi Huang burned books and pit Confucianism, this book was lost. I never thought that it was hidden in the scalp volume behind this ordinary medical book.

"Senior, this volume of the Neijing can't be the lost Neijing of the legendary medical ancestor Bian Que, right?" Shangguan Feixue still couldn't believe it, and asked Nangong Hong.

"Nine times out of ten. Nangong Hong still hadn't recovered from the excitement, and replied in a trembling voice.

Shangguan Feixue and Nangong Hong carefully read the records in this Neijing several times from beginning to end, and couldn't help but be shocked in their hearts, there were actually some cures that they had never heard of and dared not think of.

"Now, the poison in your body has been cured!" Nangong Hong pointed to a piece of "marrow washing prescription" and said excitedly to Shangguan Feixue.

"It seems that the disease is in the bone marrow, and the fate belongs to it, so there is nothing to do. This account is incorrect. Shangguan Feixue also said with a little excitement.
