Yaoxian Valley is located in the eastern coastal area of the human world, according to legend, the valley lord Nangong Yu is a descendant of the Shennong clan, in the early years was a traveling doctor, and by chance a chance to obtain priceless treasures and heirloom medical books, so he founded Yaoxian Valley.

According to Nangong Yu in this legendary medical book, there is a mysterious place in the world called "Immortal Country", where people can be immortal by eating immortal grass, so that since then Nangong Yu has been obsessed with looking for the immortal country and seeking the art of immortality. This person does not have a good reputation in the rivers and lakes, and he is not a philanthropic person.

Nangong Yu has a strange temperament, treating diseases and saving people is not for fame and fortune, nor for the benevolence of doctors, many people who come to seek medical treatment are turned away, claiming to only treat people who are destined, and his disciples are the same.

It is said that the medical fairy has never seen him out of the valley since he entered the Valley of Medicine Immortals, which is quite mysterious, and no one in the world has seen this person except the Lord of the Valley of Medicine Immortals, nor does he know the name of this person.

Yi Han had also heard of Medicine Immortal Valley, and he had some doubts in his heart, and said: "It's just that Medicine Immortal Valley has always asked about mundane things, so I don't know if I will be willing to help." ”

"Nangong Yu won't, but this medical immortal may be. Yuen Long seemed to be very confident and expressed his guess, "Judging from the patients treated by this medical immortal, he seems to be particularly concerned about the symptoms that ordinary doctors are helpless about, and even personally visit the door to treat them, which is different from Nangong Yu's style of acting." The disciple thought he could give it a try. ”

The eldest disciple and the second disciple of Luo Yanfeng are siblings, and the two look exactly the same, but their temperaments are completely different. Brother Yuen Long acted calmly and thoughtfully, and Yi Han was very relieved to leave many things to him to do, and even if he didn't explain him, he could understand and do a good job.

And the younger brother Yuankang acted absurdly and playfully and recklessly, from time to time he encouraged the disciples of other peaks to hunt birds and fish together, and sneaked out to play while he was going down the mountain to eliminate demons, which can be described as a frequent visitor to Si Guoya.

Yuen Long also didn't want Yi Han to worry about Cen Duxiao's affairs, and wanted to share more for Yi Han, so he paid special attention to these news.

Yuen Long has always attached great importance to the master of the family, and won Yi Han's trust, when Yi Shugui was not born, Yi Han also had the idea of accepting him as a righteous son and cultivating him to become the next head in the future, but he was strongly opposed by his wife Nie Chunying.

Until now, Yi Han still thinks that if he returns to the mountain one day, Yuen Long will be more suitable for this head than his son Yi Shugui in terms of cultivation and temperament. And Yi Shugui, the kid, has no interest in managing the sect, and he blames himself for spoiling him, and he only knows how to fight and laugh all day long.

In fact, the news came to Yuen Long to confirm and inquire in person, and Yuan Kang, who went down the mountain together, didn't know where to sneak to play, and Yuen Long also had no way to take this younger brother, but there was an unexpected gain when he went to find Yuan Kang.

On that day, Yuen Long and Yuen Kang went down the mountain to get rid of the demons and stayed at the Xiangju Inn at the foot of the mountain.

Yuen Long was helpless, and after the completion of the demon eradication task, he went to Linxi Town, and as soon as he entered Linxi Town, he encountered a strange thing.

Linxi Town lives by the river, most of the residents of the town live by fishing, and recently the town caught a big fish weighing more than 200 catties of catfish, the people who have eaten it are vomiting and diarrhea and are sluggish, and the state is like being poisoned, but the doctor can't see the problem.

After Yuen Long found Yuankang, he blamed Yuankang for being too irresponsible to play before the task was completed, Yuankang was aggrieved, saying that it was the inn Xiaoer who told him that Yuen Long came here first, and he came with him, and the note was not left by himself at all. But Yuen Long confirmed that the note was indeed Yuen Hong's handwriting. The younger brother had always acted absurdly, and Yuen Long thought that it was an excuse he had made for fear of being punished, so he said no more.

So, Yuen Long and Yuen Hong went separately to visit the homes of those who were sick, but they did not see any signs of poisoning or evil, and there was no trace of demons in the town.

Just when everyone was worried, a mysterious man wearing a hat veil who couldn't see what sect he was was, appeared in the town and saved these patients, what method was used by the two brothers did not know, only that no one else was allowed to be on the scene when this person was treating the patient, so no one saw it, but the patients were all recovered.

Later, Yuen Long thought that this person was so good at dealing with the symptoms of delirium, so he took advantage of the mysterious man's lack of attention to cast a tracking spell on him, until he returned to the Valley of Medicine Immortals, and combined with the rumors he had heard since he came down the mountain, he speculated that this person was most likely the rumored Medicine Immortal.

Yuen Long told Yi Han about this experience, and Yi Han thought about it and said, "Then you can give it a try, and you can accompany Twilight to the Medicine Immortal Valley, and there will be a response on the way." ”

Yuen Long replied respectfully: "The disciple obeys the order and protects the little junior sister thoroughly. ”

At this moment, Yi Shugui came in in a hurry, and he heard the conversation between Yuen Long and Yi Han just now. When he came in, he said, "Dad, let me go with Xiaoxiao too, you also know that I can't stay too far away from her, otherwise I will get sick." ”

Yi Han thought of Yi Shugui's illness when he was a child, and it seemed to have some connection with Cen Duxiao, maybe this medical immortal could help see why this was so. Then he agreed, and instructed: "This is a long way to go, the three of you must be more careful, don't be reckless when you arrive in the Medicine Immortal Valley, you must know the etiquette and abide by the rules, and go to the tent to pay more silver taels in case of emergency." ”

Yi Shugui was ecstatic and ran behind Yi Han and pinched his shoulders and beat his back, and said, "So, Dad, did you agree?" Xiaoxiao can also come out of Siguo Cliff, it is damp and cold there, and her body will definitely not be able to stand it." ”

Yi Han smiled helplessly: "You guys should leave immediately, and I will explain to Master Zhuang." Then he pinched a trick and withdrew the barrier of the cliff.

"I know that my father is the best, so I'll go and pick Xiaoxiao back first. After speaking, he flew directly to the Siguo Cliff.

When he arrived at Siguo Cliff, Yi Shugui saw Cen Duxiao lying on the stool in the pavilion, his eyes were closed, and he couldn't help but feel tight, so he hurriedly stepped forward to check, and was relieved to see that there was still a breath and pulse and no fever, and said helplessly: "Xiaoxiao, are you a pig, you can sleep so cold!"

Seeing that Cen Duxiao was sleeping soundly, Yi Shugui couldn't bear to wake her up, so he took off his robe and covered her, and sat aside and waited for her to wake up.

Cen Duxiao had a dream, a strange dream. In her dream, she appeared by a river that was not like the one she had ever seen.

The water of this river is black and bottomless, and there are many colorful halos floating on the river, like colorful fireflies.

There was a long-haired woman in black standing on the bank of the river, her face couldn't be seen clearly, and she could only hear her say: "You ruthless bad girl, Fusang Jun is very affectionate to you, but you treat him like this, then remember everything you have done, and repay him in the next life......"

"Fuso, Fuso, Fuso......"

Cen Duxiao muttered this name, where had she heard of this name, it was both familiar and unfamiliar, why did her heart ache faintly when she thought of this name?
