Shangguan Feixue's sentence comes from a record of Bian Que's meeting with Cai Huangong in "Han Feizi Yu Lao", which contains Bian Que's words: "The disease is in the gut, the soup is ironed, the skin is within the reach of the needle stone, in the stomach and intestines, the fire is within the reach, and in the bone marrow, where the order belongs, there is nothing to do." ”

It means that minor diseases can be achieved by decoction between the skin textures, diseases in the muscles and skin, which can be cured by acupuncture, diseases in the intestines and stomachs, which can be cured with gunpowder soup, and diseases in the bone marrow, which are under the jurisdiction of the gods, and there is no way for doctors to cure them.

The reason why Shangguan Feixue said that there was a mistake in the book was because the "marrow washing formula" did record a method that could remove the poison that entered the marrow.

"The account is not necessarily wrong. Nangong Hong shook his head slightly, pointed to the "marrow washing formula" and said to Shangguan Feixue: "Let's not say that these few things are difficult to collect, just talk about this treatment method, who would dare to let the king try it?

Shangguan Feixue looked at the record of the "marrow washing prescription" again, and couldn't help nodding yes.

In addition to some things that are not easy to find, such as the snow mountain Tai Sui, the polar ice silkworm, and the golden scorpion in the sand, the people who need to be treated also need to be treated in the hundred-year-old "dragon" pond and drink the blood of the hundred-year-old giant python every day, for a total of 7749 days. This kind of treatment is tantamount to letting the treated person kill himself, so how can Bian Que go to Cai Huan Gong to say. No wonder there is "the fate of the priest, helpless." ".

After confirming that this sheepskin was the lost "Neijing", Nangong Hong asked Shangguan Feixue to call Nangong Yuhan and Su Hongsleeve together.

"Grandpa, what is the matter with you calling us here in such a hurry?" Nangong Yuhan entered the room and asked puzzled when he saw Nangong Hong, who was smiling.

"What's the matter? Of course it's a happy event. Nangong Hong sold Guan Zi and said with a smile.

"What's the happy thing?, do you have all the things that know the five poisons that kill you?" Nangong Hong also joked with a smile.

Since Nangong Hong agreed to teach Shangguan Feixue medical skills, Shangguan Feixue took the initiative to confess that he had compiled this poison.

In fact, Nangong Hong had already guessed that this "life-killing five poison scatter" was a non-existent thing, which was why he was not in a hurry to find the preparation of this poison.

In Nangong Hong's words, there are two poisonous insects in the formula that Shangguan Feixue said, so how can they be used in the same poison.

The reason why Nangong Hong did not expose Shangguan Feixue in public was because Nangong Hong knew that Shangguan Feixue was the descendant of Xiao He, the jade-faced Langjun, and he and Xiao He had an intersection, which was regarded as giving Xiao He a face, and he also wanted to see what Shangguan Feixue would do.

But no matter how Nangong Hong explained, this matter was taken as a joke by Nangong Yuhan and used to make fun of Nangong Hong.

Nangong Hong glanced at Nangong Yuhan, and said unhurriedly: "It's about the poison on Feixue's body." If you don't want to hear it, forget it. ”

"What, about the poison on Brother Feixue's body?" Nangong Yuhan and Su Hongsleeve were shocked when they heard this.

"Grandpa, come and listen. Is there a way to cure the poison in Brother Feixue's body?" Nangong Yuhan asked eagerly.

"You!" Nangong Hong smiled and tapped Nangong Yuhan's forehead with his finger, and continued: "In your heart, you, Brother Feixue, are more important than anyone else. ”

As soon as Nangong Hong's words came out, Nangong Yuhan's face immediately flushed with shame, Shangguan Feixue was embarrassed and didn't know how to say it, only Su Hong's expression inadvertently changed, and he smiled.

"Senior Nangong, can the poison on Brother Feixue's body really be cured?" asked Su Hongsleeve to Nangong Hong.

Nangong Hong also realized the embarrassment of the scene, and quickly changed the topic back, "Yes." Feixue and I just discovered the strange book of the medical ancestor Bian Que, and there is indeed a cure for the poison that penetrates the marrow. ”

"Great. Su Hongsleeve and Nangong Yuhan said loudly in unison, their joy overflowing.

"Pull it down and get all the medicines in this prescription is the most important thing. Nangong Hong continued.

"Tell me, what can we do?" said Su Hongsleeve and the others.

"So be it. From tomorrow, we will go separately to find things like the Snow Mountain Tai Sui and the Polar Ice Silkworm, and then go to find the Centennial Dragon Pond after collecting all these things. Nangong Hong said to Shangguan Feixue and others.

"Senior, it's not easy to collect these things, I'm afraid you need to run around for a year and a half, you're old, it's not easy to travel and travel, I want you to stay in this valley, let me collect it." Shangguan Feixue said to Nangong Hong.

"It's hard to believe that you can have such a heart. Nangong Hong nodded with satisfaction, and said with a smile: "Although my old man's muscles and bones are not as good as you young people, they are not too bad. In this way, the three things of the Snow Mountain Tai Sui, the Polar Ice Silkworm, and the Golden Scorpion in the Sand will be handled by you young people, and the other things that I already have, I can also collect them on the mountains near the Medicine King Valley, so I will do it. One year is limited, you take Yuhan and Red Sleeves with you, and after a year, no matter whether you can collect these things or not, you have to come back and continue to soak in the cold pool. ”

"Okay. Shangguan Feixue nodded in agreement.

The book is simple, Shangguan Feixue and the others packed up that day, and the next morning, everyone left the Medicine King Valley.

Shangguan Feixue and the others didn't have the opportunity to move around the rivers and lakes before, and they were full of confidence before leaving the valley, but as soon as they got out of the valley, they immediately looked dazed and didn't know where to go.

"This Snow Mountain Tai Sui, the Polar Ice Silkworm and the Golden Scorpion in the Sand are all extremely rare things, although Grandpa Nangong told us where these kinds of things are infested, how can we find them?" Su Hongsleeve asked Shangguan Feixue and Nangong Yuhan with a blank face.

"I don't really know about that. But according to my grandfather, as long as we go north, we may gain something when we reach the bitter cold land of the north. Nangong Yuhan said.

"What Miss Nangong said is good. But the three of us have limited knowledge of the information in the rivers and lakes, and blindly looking for it may be counterproductive, so I want to go to the Song Mansion first, Song Lingshan's grandfather is very well-informed about the information in the rivers and lakes, and may be able to provide us with some useful advice. Shangguan Feixue said to Nangong Yuhan and Su Hongsleeve.

"It's good that we haven't seen Miss Lingshan for a long time, and we don't know what happened to her now. Nangong Yuhan said with a smile.

"We've been in Medicine King Valley for nearly a year, and I don't know what happened to Liu Xiu and Lu Sheng now. Su Hongsleeve muttered.

mentioned Song Lingshan, which made Su Hongsleeve immediately think of Liu Xiu and others who had fought with him. From the camp of the dead to everyone walking the rivers and lakes with Shangguan Feixue, Su Hongsleeve and Liu Xiu and others have experienced life and death many times, and this friendship has been deeply imprinted in her heart.
