After leaving the tea shop, Ling Feng went straight to a medical hall on the outskirts of the city, according to Futuo, although this medical hall is located in the suburbs of the city, but it has cured a lot of strange and difficult diseases, and the medicinal materials it uses are extremely rare in the medicinal herb shops in the city, and some of them have not even heard of the shopkeeper of medicinal materials, so the doctor often takes his granddaughter to the depths of Wanfeng Ridge to collect medicinal materials, and is more familiar with the situation of Wanfeng Ridge than some hunters, but because of this, this medical hall is often closed, and it depends on luck to see a doctor.

Ling Feng came to the medical hall, and it happened that the doctor was seeing him, so Ling Feng found a chair and sat down, waiting for the doctor to be available.

The medical hall is very simple, the consultation desk is just an ordinary square table, there are a few chairs, and there is a bed in the corner, which is also quite simple, I think it is for seriously ill patients, in addition, there is a door behind the room that blocks the view with a curtain, which should be the resting place of the ancestors and grandchildren, Ling Feng naturally will not use his divine sense to explore at will unreasonably.

Ling Feng sat for a while, the pharmacist also looked at three patients, there were at least two or three more at the moment, Ling Feng felt bored, so he thought of the blue melancholy grass that he had hidden before, there were about twenty or so plants, Ling Feng took out a blue melancholy grass and carefully examined it in his hand.

"The prison keeper once said that the Blue Sorrow Grass is derived from the Blue Sorrow Flower, and it has a trace of resistance to the Heavenly Tribulation. Therefore, the six major forces will use the name of Dabi to collect blue melancholy grass to fight against a small amount of calamity, but I don't know if this blue melancholy can be used as an alchemy or medicine? ”

The pill mentioned in the cultivation realm is actually a collective term for pill and medicine, and pill and medicine have the same origin, but they are different.

Dan, refining it with Ding, refining the spiritual materials according to the proportion and order of Dan Ding, during which it is also necessary to mark a specific Dan recipe and control the fire to have a certain chance of becoming Dan, and the quality of Danding and flame also greatly affects the final Cheng Dan.

In addition, those who have advanced cultivation may be able to refine some low-grade pills of inferior quality with their cultivation insight, but it is extremely difficult to become a real Dan Master, even if Ling Feng was an immortal in the Qingyan Immortal Realm, he has not seen many alchemists.

Medicine, on the other hand, is much simpler, requiring only a certain proportion of the specified herbs to be prepared and then decocted or made into pills. Compared with Dan, medicine only has its shape, but not its rhyme.

"Where did you find this herb?"

A woman's voice suddenly sounded from behind Ling Feng, who had long been aware of this woman's arrival and had not put away the blue melancholy.

"Doesn't the girl know this grass?"

"The little girl's name is Wen Ruyi, and it is her grandfather who sees the doctor, so she just disturbed the son, and I hope the son will not blame him. But I see that Childe has a ruddy complexion and sufficient blood and energy, not like he is coming to see a doctor, I don't know what Childe is doing? ”

This woman was dressed in purple, it was Wen Ruxi, the granddaughter of the old doctor Wen Hu, Wen Ruxi did not directly answer Ling Feng's words, but asked Ling Feng's intention first.

Ling Feng then put away the blue melancholy grass and said, "I heard that Doctor Wen and Miss Wen have been walking in the Wanfeng Ridge all year round, so I wanted to come here to ask for some experience in the mountains."

"I saw that the medicinal materials in Gongzi's hands just now are a little extraordinary, could it be that he is interested in pharmacology and plans to go into the mountains to find medicine?"

Ling Feng shook his head, "I don't know anything about pharmacology, I also got this grass by accident, there are other things going into the mountain this time."

"There are many people entering Wanfeng Ridge, why are you looking for only my ancestors and grandchildren?"

"I heard that unlike those hunters, the medicinal herbs collected by Doctor Wen and Miss Wen are extremely rare, and almost all of them are dangerous and strange, and what I am looking for is not a simple place."

"In this case, let's wait until my grandfather finishes the consultation, I am shallow, maybe I will miss the matter of the son."

Wen Ruxi didn't mention the matter of Lan Yucao again, and after saying goodbye, he went to the back hall from behind the curtain, and Ling Feng also quietly waited for Wen Hu to finish his consultation.

It was almost dark, Wen Hu stretched his waist, and finally finished reading today's patient, and when he was about to go to the back hall, he saw Ling Feng sitting motionless on the side, which startled Wen Hu.

Only then did Ling Feng get up and clasp his fists to Wen Hu and said, "Doctor Wen, under Ling Feng, there are some things I want to consult, I don't know if it's convenient."

Before Wen Hu could speak, Wen Ruxi came out of the back hall, pulled Wen Hu and said, "Grandfather, you are a little tired after a day of consultation, it is better to let Ling Gongzi dine together, and talk about it in detail later."

"That's fine, what does Ling Gongzi think?"

"Then I'll bother the two of you."

Although Ling Feng had already been able to open the valley, he still accompanied the two of them to eat. Speaking of which, Wen Ruxi's cooking skills are really good, and the seemingly simple ingredients are made with a thousand flavors.

"I'm not going to hide it, I'm looking for a vein, but I only know that this vein is located in the depths of Wanfeng Ridge, and its shape resembles a mushroom, I don't know if Doctor Wen has seen it."

"Mushroom-shaped peaks are not uncommon in Wanfeng Ridge, I know of five places, but I don't know which one Ling Gongzi is looking for."

"None of the five peaks are there that often do strange things?"

Since there is a Heavenly Star Stone Vein, that mountain peak will inevitably be affected, and Ling Feng asked this question.

Wen Hu took out a self-made map, pointed to one of them and said: "This is the map I usually draw by collecting medicine, you may be talking about this mountain, but I suggest you don't rush to go, this mountain peak disappears from time to time, but no one who enters can come out alive"

Ling Feng glanced at the map in Wen Hu's hand, memorized all the routes in his mind, and then took out a blue melancholy grass and said:

"I used to see that Miss Wen seemed to be interested in this grass, and as a thank you, I gave this grass to Miss Wen."

Wen Ru had seen the Blue Grass before, but now that he didn't have much reaction when he saw him again, it was Wen Hu, and when Ling Feng took out the grass, his hands began to tremble with excitement.

"It's... This... This is the Blue Sorrow Grass."

"Blue Sorrow Grass? I got this grass by accident, I don't know if Dr. Wen knows the origin? ”

Wen Hu hesitated for a while, and finally sighed and said: "It's not a secret, my medical skills are handed down from my ancestors, it is said that my ancestor was a Danshi, and Danshi is far more advanced than a doctor, even if the immortals who fly to the sky and the earth respect him very much, but the ancestor suddenly disappeared without a trace, leaving a classic, and it is in this classic that I have seen this thing."

Ling Feng didn't expect that this ancestor was actually a Dan Master, mortals might not know what a Dan Master meant, but Ling Feng did.

"Is there a detailed description of the function of this grass in this book?"

"It is recorded in the book that the Blue Sorrow Grass is one of the five derived grasses of the Blue Sorrow Grass, and there are very few records of the Blue Sorrow Grass, but the five derivatives of the Blue Sorrow Grass are more detailed, Childe waits, I will take this book and let Childe take a look"

After a while, he saw Wen Hu walking from the room with a thick and simple book in his hand, and Ling Feng saw that the book had a few big characters written on it, "Qiming Dan Dao Program".

Ling Feng opened the book, and the first page was an introduction, writing: There is no perfection in cultivation, and the way of Dan is to use the Grass and Wood Spirit Method as an auxiliary means to make up for the one who has escaped.

There are many elixirs and herbs brewing in heaven and earth, and the medicinal effects are different, or they are difficult to absorb directly, or they may have a single effect, and after refining them into elixirs, they will surpass their original value, but due to the different techniques of the elixir, the elixirs will also be different.

Then there is the division of the Dan Master, the spiritual material, and the elixir.

Danshi is divided into Lingdanshi, Wang Danshi, Tiandanshi and Xiandanshi, the minimum requirement of Lingdanshi is to be able to refine the foundation-level elixir, the minimum requirement of Wang Danshi is to refine the Yuanying-level Wang Dan, and the Tiandanshi naturally needs to refine the Tribulation-level Tiandan, as for the Xiandanshi, it needs to refine the real elixir.

If it was at the peak of Ling Feng, he might be able to barely refine the Yuanying-level Wang Dan with his cultivation, but now his cultivation is afraid that he can't even refine the Foundation Spirit Pill.

The spirit grass elixir and the elixir are divided into almost the same, divided into spirit-level spirit grass, king-level spirit grass, heaven-level spirit grass and immortal-level spirit grass.

After the book, there were some records of Danfang, Spirit Grass, and Pills, and Ling Feng really found a record of Blue Worry Grass.

"Blue Sorrow Grass, fairy-level spirit grass, after the flower blooms, it will fall off by itself, its flower will absorb the grass body, and then exist in the form of flowers, it has a probability to derive five kinds of spirit grass, and the remaining four derived grasses are extremely difficult to grow, only the Blue Sorrow Grass is the easiest to grow, and the Blue Sorrow Grass is only a spirit-level spirit grass"

Then there was the description of the Blue Sorrow Tribulation Grass, which was roughly the same as what Ling Feng saw, but this grass had two other functions, one was used to refine the Crossing Erdan.

The Doerdan is not strictly an elixir, but rather a disposable magic weapon, which can be thrown out when the Tribulation comes, and this Pill will explode, releasing a force to envelop the Tribulation, and then slowly dissolve it. Of course, if the power of the Heavenly Tribulation is too strong, no amount of Crossing Erdan will be useless.

Another effect is that it is used as a staple medicine in the mortal world, and its medicine can help women to have a difficult birth.

If the fetus is not in the right position, the fetus is difficult to deliver, or premature birth will kill at any time, if this herb is decocted together with several other herbs, it can help to give birth to a child smoothly.

This effect is only useful for mortal women, and in the cultivation realm, there is almost no such thing as dystocia.

Wen Hu is so excited because of this, he has practiced medicine for many years, and he has seen how many people have died in childbirth, even Wen Hu's daughter, Wen Ruxi's mother Wen Wan also died of dystocia, and Wen Hu's medical skills could not save her.

The one who caused Wen Wan's dystocia was Wen Ruxi's biological father Tang Chu, who disappeared after killing Wen Wan, so Wen Ruxi called Wen Hu his grandfather instead of his maternal grandfather, and followed his surname and depended on each other.

In addition, the book also records some alchemy techniques and pill recipes, when Ling Feng left the country, the sect had a special Dan master, and there was no shortage of resources, and he knew that without the wood spirit root and fire spirit root, alchemy would inevitably be half the effort, so he never considered alchemy, and now he had to consider his own alchemy.

Although there are also some Danfang records in the sect classics obtained from the Tianwu Sect, most of them are quite esoteric, not as detailed as this book and suitable for beginner learning, so Ling Feng has some thoughts about this book.

"I don't know if Doctor Wen can cut love, in addition to this Blue Sorrow Grass, this exercise is also in exchange"

The exercises are a spiritual-level eight-grade exercises that Ling Feng selected from the classics of the Heavenly Martial Sect, and he thinks that he can exchange this introductory Dan Dao program.

Where does Wen Hu know what exercises, in Wen Hu's opinion, the Blue Sorrow Tribulation Grass can still be cultivated, and the classics have long been familiar with it, and the value of a Blue Sorrow Tribulation Grass can top ten such books, where does he know that the exercises that he ignores are the most important, but Wen Ru showed an extremely curious look at the exercises.

After this trip, Ling Feng gained a lot, not only knew the whereabouts of the Tianxing Stone Vein, but also obtained the Dan Dao Program, and Ling Feng, who was in a good mood, then said goodbye to Wen Hu and Wen Ruxi, and then went to the location of the Tianxing Stone Vein.
