The jade pendant owned by Gu Master Lu Fang mentioned in his mother's mouth, Gu Shun also vaguely had a memory of it, which he saw from the books in his father's bookcase that he had never read.

Xiangxi is mountainous and swampy, the miasma is dense, the number of various poisonous insects is countless, and the people who hunt and gather in the mountains are often bitten by poisonous insects, and over time, they are also familiar with the temperament of various poisonous insects and the herbs for detoxification.

Later, the magic of witchcraft gradually became popular in Xiangxi, and no one knows when this witchcraft originated and when it spread in Xiangxi.

People only know that because of the special climatic conditions in Xiangxi, in addition to many notorious allusions in the field of Gu refining and refining, seven or eight out of ten poisonous insects in the world come from Xiangxi and the southwest region, and there are even Miao Jiang Gu girls and evil arts such as descending heads.

Later, the Ancient God Sect developed its power in Xiangxi, learned the preparation technology of Gu worms, and with the expansion of the Ancient God Sect, it was wanton in the Central Plains, so that Gu worms were linked to the Demon Sect, which became a lingering shadow and synonym.

Among the many legendary figures related to Miao Jiang and Xiangxi, Gu Master Lu Fang is definitely the most well-known among them, and there are even Gu masters in the world who have won the honor of their ancestors.

Lu Fang is said to be the apprentice of Guiguzi, who learned from Guiguzi, and after coming out of the mountain, he did not use it like other disciples, eager to be appreciated by the monarch, and paid homage to the prime minister, turning what he had learned all his life into a great plan for the family and the country, and assisting Mingjun to achieve a hegemony.

On the contrary, after Lu Fang went down the mountain, he traveled among the people, and even the people's sufferings could not be changed by the rulers, and the decay and stupidity of many princes were unimaginable.

Lu Fang was greatly disappointed by this, and chose a different path from his fellow disciples and brothers, practicing medicine to save people.

Long before apprenticeship with Guiguzi, Lu Fang was a fledgling Langzhong, and learned a few medical skills from his uncle in the countryside.

Lu Fang, who changed his mind, decided to complete the master's entrustment and teachings in a different way, and returned to his old profession to practice medicine and save people.

He did not stay in one place for a long time, but walked and watched, while increasing his medical skills, he could also help the people along the road to treat various diseases and miscellaneous diseases, and benefit one party.

He is most famous for proposing the earliest method of treating Gu worm toxins, and systematically giving a set of detoxification and removal plans for Gu worms, leaving a pioneering and valuable experience for the local Gu master and Langzhong in the Central Plains.

At that time, witch Gu was not really popular, but there were still many people who were deeply affected by Gu insects, and anyone who was bitten by Gu insects or had Gu poison in their bodies looked no different from ordinary poisonous insects, and many of them did not even have any symptoms.

Patients often treat it as an ordinary poisonous insect bite and don't take it to heart, but once the worm attacks, it is impossible to treat them.

At that time, even the most experienced Lang Zhong was powerless against the Gu worm's toxin.

While traveling all over the world, accumulating experience, and observing the sufferings of the people, Lu Fang practiced medicine to save people, saved lives and helped the wounded many times, winning the popularity of many people everywhere he went, and his reputation changed from being ignored to gradually becoming famous.

Everywhere he went, many people who wanted to seek treatment from him were already waiting there.

On that day, he practiced medicine and walked to Jingxian County, north of Xiangxi, where a village woman stopped him and led him to a grass house.

Inside the grass house was a man with hot teeth, teeth and claws, and when the man saw someone, he immediately grinned like a mad dog, and struggled with his hands and feet to bite the person he met.

If it weren't for the fact that the man was chained tightly, the person inside might have been in danger of being bitten.

After inquiry, Lu Fang learned that the one who was chained was the old woman's son.

Before the incident, he followed a fellow villager in the village to Xiangxi to deliver goods, but he encountered an accident on the way, the fellow villager was killed, the goods were robbed, and everyone was taken captive.

Originally, the old woman thought that her son must have died, but she did not expect that her son would come back by himself a month later.

The old woman was relieved that her son was covered in nothing different except for some bruises and fright.

Many of his fellow villagers came to see him and were glad that he had saved his life.

But the good times did not last long, and within three days of his return, the old woman's son began to become abnormal.

He was extremely itchy, afraid of light and water, and extremely restless.

The old woman thought that it was only her son who was too frightened to show such symptoms, and did not take it to heart, but within two days, his body became more and more wrong, and the whole person was like crazy, and he bit many fellow villagers everywhere, and also bit off half of the ear of a child in the village.

The situation is getting more and more serious, and the people in the village invited Lang Zhong for him, and Lang Zhong has no way to deal with this condition, except for his high body temperature and mental madness, he is no different from a normal person.

However, the old woman's son's performance was obviously not what a normal person should be, and Lang Zhong, who was helpless, could only prescribe him a few soothing herbs, hoping that his condition could recover on his own.

However, the heavens did not fulfill people's wishes, and after drinking a few herbs, the old woman's son's condition became more serious, and the whole person was like a mad dog, biting people when they saw them, and even the old woman was bitten by people.

The villagers feared that he would harm more people, so they chained him to a barn that used to raise cattle.

When Lu Fang went, the old woman's son had been locked up for almost a month.

The whole person is getting thinner and thinner, but he is becoming more and more aggressive, and the most frightening thing is that he can no longer eat cooked food.

Because the cottage used to be a cowshed, and there was a chicken coop nearby, and on that day, a chicken happened to enter the cottage to feed, and somehow he caught it, and when the old woman came to deliver food, she was startled by the scene in front of her.

The ground was covered with chicken feathers, the whole chicken had been swallowed by him, and there was blood all around, including his face.

Ru Mao drank blood, was irritable, and danced his teeth and claws, this series of abnormal behaviors even made people suspect that this person might be a monster in human skin, and the villagers were afraid to avoid it.

After Lu Fang checked that person's condition, he was also full of confusion, because he had practiced medicine for many years, and he had seen all kinds of diseases, large and small, even mental diseases, and he had also greatly alleviated or even cured the symptoms of many people through treatment.

But he had never seen anything like this, so he took medicine and dispensed it with experience, hoping to save the old woman's son.

In this way, Lu Fang lived in this small village, and while concentrating on the study of this disease, he looked for a cure or a way to improve his condition.

After Lu Fang's all-out treatment, the old woman's son's condition became worse and worse, until that day, the son suddenly returned to normal, and the mother and son hugged each other and cried.

The old woman thought that Dr. Lu had saved her son and thanked Lu Fang for her kindness, but Lu Fang knew that the old woman's son was dying for a short time, and everything now was just a return to the past.

Lu Fang didn't say anything about it, he was afraid that the old woman wouldn't be able to bear the blow and faint completely, so his son's mind would be confused, and he couldn't take advantage of this time to ask what was going on.

With the old woman's son's narration, Lu Fang learned about the Gu worms in Xiangxi for the first time, as well as the witchcraft of using the Gu worms as weapons.
