Waiting for Fang Rui to leave, Yun Feiyu entered the attic of the Longyin Pavilion C Department containing 10,000 volumes of medical and poisonous books, this attic is divided into four floors, there is no book collection at the bottom layer, only a stone tablet stands in the middle, Yun Feiyu stepped forward to take a look, it turned out that the stone tablet was engraved with a brief introduction to the distribution of the books on the top three floors, what kind of books are hidden in several layers, which bookshelves, at a glance, the second floor of the medical poison building is the Baicao Building, which mainly contains all kinds of medical books, the third floor is the Ten Thousand Poison Building, which contains all kinds of poison poison related classics, and the fourth floor is the strange poison and medicine building, which hides the rare elixir pills and foreign poison formulas and solutions in the world。

Gu poison as a poison secret technique, on the stele solemnly marked that it belongs to the world's foreign poison, the relevant books are hidden on the fourth floor, Yun Feiyu went directly to the fourth floor, when he climbed the stairs, Yun Feiyu found that the space on the second and third floors below was very wide, there were many bookshelves inside, and there were countless books, Yun Feiyu couldn't help but be secretly frightened when he saw it, secretly thinking that so many books should be read by himself, I really don't know when he can finish reading!

When he climbed to the top floor, he found that the fourth floor was slightly smaller, although the bookshelves were much smaller than the lower two floors, even so, Yun Feiyu estimated that there were hundreds of books in this layer, and the styles and types of books were varied, from a few pieces of ancient books sewn from knives and bamboo slips that had been stored for many years, to brocade cloth with a few feet of pen and ink, and even a thin sheet of metal with a few paragraphs of text engraved on them were also included here as a collection, Yun Feiyu couldn't help but sigh, these things really don't know how they were collected here!

On the fourth floor, Yun Feiyu rummaged for an hour, and finally found a copy of "Gu Poison Record", which was explained in a relatively understandable and detailed manner, so he sat on the ground with this book in his arms and leaned on the bookshelf to read it carefully.

This "Gu Poison Record" is a summary of the records of the generation of Jianghu generation in the rivers and lakes a hundred years ago, and the Gu master Mrs. Jinhua has a detailed description of all kinds of Gu poisons she knows from preparation to use, the original name of this Mrs. Jinhua is impossible to test, because she is as beautiful as a flower and is good at using the golden silkworm Gu poison, so she was called Mrs. Jinhua by the people in the rivers and lakes at that time, and her Gu poison application has reached the realm, not only a wide variety, different poisons, and the methods of Gu poison are strange and unpredictable, which really made the people of the rivers and lakes at that time hear the discoloration!

Mrs. Jinhua introduced at the beginning of "Gu Poison Record": "The hundred Gu in the world vary from person to person, and the common ones in my rivers and lakes in the past 20 years can be roughly divided into thirteen types: Gu Gu, Snake Gu, Golden Silkworm Gu, Mad Gu, Medium Harm Gu, Change Gu, Swollen Gu, Yin Snake Gu, Raw Snake Gu, Three Corpse Gu, Fragment Gu, Stone Gu, Loach Gu." ”

But looking at these many Gu species, Yun Feiyu only felt a headache, he thought that Gu poison was a strange poison, how could he still subdivide it so much, and still think about whether his Heart Eroding Gu belonged to one of these thirteen species, or was it an alternative new species cultivated by Duan Fangrui himself?

Continue to read on, Mrs. Jinhua described in detail in the book the symptoms of the attack of the thirteen kinds of Gu poison, the method of going down the Gu and the method of making the Gu, these thirteen kinds of Gu poison symptoms are really strange and shocking, such as crazy Gu, as the name suggests, it can make people hallucinate and laugh and scold impermanence as if crazy; Loach Gu, let the Gu person in the body like three or five loaches wandering around, up the throat, down to the anus, if not treated in time, he will definitely die! The three corpse Gu sucks the host's essence blood and injects toxins, causing the host to have convulsions all over the body, causing poisonous sores, and resting until death......

Looking at the various Gu poison symptoms, Yun Feiyu shuddered! Because most of these Gu poisons are fatal, and the thing on the inner vein of his own body also tortures him to death, and seeing all kinds of Gu poison production methods, Yun Feiyu is even more disgusted and wants to vomit, most of these thirteen kinds of Gu poisons are used with dozens, or even hundreds of kinds of poisonous insects and poisons put together to bite and devour each other, the only one that survives is Gu, and then after special feeding, it becomes all kinds of Gu poisons, and some are prepared with the corpses of various strange poisons developed into powder and some disgusting raw materials, thinking about the kind of things that are lodged in his body, Yun Feiyu is really a little unbearable, and reluctantlyAfter reading "Gu Poison Record", she got a little gain, put the book back in its place, Yun Feiyu couldn't help but walk to the attic window to relax and panting, secretly hating in her heart, this little girl Duan Fangrui is really vicious in her heart, how can she use Gu poison to harm people at such a young age!

And at this moment, Duan Fangrui, who was secretly hated by Yun Feiyu, was sitting proudly in a bamboo house, whispering to the woman lying on the bed next to him about his 'great achievements' in recent days!

The woman's head was full of green silk scattered on the pillow, with a pair of light eyebrows, her eyes closed, but the corners of her mouth were slightly upturned, as if with a slight smile, her appearance was dignified and her temperament was gentle and moving, she was lying quietly on the bed as if she was asleep and waking up, but she had no reaction to Duan Fangrui's self-talk next to her, and Duan Fangrui was not surprised, because since she had known the master, it had been almost eight years, and the master and mother were lying there quietly every day, with a chuckle but the six senses of impermanent people, but she didn't say a word, and she didn't move!

The door of the bamboo house creaked open, and an old man in Tsing Yi with white hair came in from outside, tall, with a slight back and a frosty face, carefully holding a bowl of decoction in his hand, and asked with a smile at Duan Fangrui: "Rui'er, what kind of trouble do you want to tell your master?"

Duan Fangrui's face was full of surprise, she stood up and ran to the old man happily, hugged the old man's waist and shook it excitedly: "Master, you are back! Have you found the purple lingzhi?"

The old man hurriedly raised the decoction in his hand, and said urgently: "Hey, hey, slow down, slow down, how old are you, you are still so childish, don't touch your master's medicine!"

Wrinkling his nose, reluctant to let go of the old man, Duan Fangrui pouted and feigned: "People were so happy just now! Master is training others, Master really doesn't care for Rui'er anymore! Rui'er is angry!"

The old man shook his head and smiled bitterly, pointed at Duan Fang Rui and said, "You, it's really getting bigger and smaller!" Ignoring her, he came to the bed with the bowl of medicine, looked at the woman on the bed with a tender face, and said softly: "Jieyu, it's time to take medicine again." ”

Carefully sat on the edge of the bed, as if unintentionally glanced at Duan Fangrui, Duan Fangrui smiled on his face, and quickly ran over to take the medicine bowl with both hands, the old man smiled and shook his head, carefully supported the woman on the bed in his arms, gently returned his scattered hair to his body, took the medicine bowl, gently blow, and then slowly gave the woman on the bed with a spoonful of medicine, and handed the empty bowl to Duan Fangrui after feeding, and gently wiped the corners of the woman's mouth, slowly put it back on the bed, and carefully straightened its green silk, and then gently covered it with a thin quilt, and then looked back at Duan Fangrui and said with a smile: "How can purple Lingzhi be so easy to find, let's say! What trouble did you get into this time?"

Putting the medicine bowl on the table in the room, Duan Fangrui came to the old man and stuck out his tongue, and replied in a coquettish voice: "Master, I gave someone someone a Heart Erosion Gu!"

The old man's face changed slightly, and he said with a slight displeasure: "Didn't I tell you, this kind of Gu poison is too ruthless, don't you use it at will? Who did you fall on? And for what?"

"It's a person named Yun Feiyu, I want him to be my Shura Guard, but he doesn't agree to anything, so I gave him a Heart Erosion Gu!" Duan Fangrui didn't tell the truth, she was directly poisoned by Gu before Yun Feiyu woke up after Wangxi Peak rescued Yun Feiyu, not because Yun Feiyu refused what she wanted!

A strange expression appeared on the old man's face, and he looked at Duan Fangrui and asked, "Rui'er, do you know what Shura Wei means?"

Duan Fangrui looked at the old man with a puzzled expression, and asked, "Isn't Shura Wei the personal guard of our Duanfang family's woman?

Secretly taking a selfie on the head, it seems that this little spirit spirit also has times of confusion, but this is also related to her age, after all, she is only thirteen years old, but she should know some things about her, the old man couldn't help but explain with a wry smile: "Rui'er, according to the teacher's knowledge, according to your ancestral teachings, the women of the Duanfang family are not allowed to marry or recruit sons-in-law, and there is only one Shurawei in her life, according to the Central Plains, Shurawei is the only lover in your Duanfang family's women's life!"

Duan Fangrui's face was red when he heard this, his heart was pounding, and he opened his mouth and said urgently: "Then, isn't it okay if I don't let him be my Shura Guard?"

The old man nodded and said with a smile: "You are still young, it is still early to choose Shurawei, don't mess with anyone to be Shurawei in the future!"

Duan Fangrui nodded shyly in agreement, and asked the master again, "Master, is there still a way to lift the Heart Eroding Gu?" Since Yun Feiyu can't be his own Shura Guard, he can't always be by his side, so it's better to be merciful and let him go!

The old man groaned a little, and replied with a serious face: "There is no cure for the Heart Erosion Gu, unless that Yun Feiyu can never stay away from you for the rest of his life, otherwise, one day he will be killed by the Heart Erosion Gu!"
