Half a month later.

In the middle of the Zhongming Mountain Range, there is an independent solitary peak with a very peculiar shape, its top and the roots of the mountain are swollen and full, but the mountainside is like a woman's thin waist is tightened, and it looks like a huge gourd with two large ends and a small middle.

It is precisely because of this that this mountain is named "Hulu Peak", and like the Royal Dragon Peak, it is also one of the most important peaks in the entire Candle Dragon Road.

The gourd peak mountain is not dangerous, the height is less than a thousand zhang, at the bottom of the mountain root, there is a very high quality spiritual spring, which can nourish all the living beings on the whole mountain peak, so that the vegetation on the mountain peak is green all the year round, and the four seasons are like spring.

And outside this peak, there is also an extremely tight defensive array, and it is open all year round, so all the elders and disciples in the gate, regardless of the inner and outer doors, if they want to enter this peak, they must pass through the teleportation hall at the foot of the mountain.

There is only one reason why this peak is so heavily protected, and that is that almost all the pills in the entire Candle Dragon Dao flow from this peak, and the alchemists cultivated in the sect also live on this peak all year round.

And on the gourd peak, the Di Dan master who can refine the pills taken by the immortals is naturally the person with the highest status.

In the past, a cultivator in the early stage of the True Immortal Realm, if he followed the normal cultivation speed, it would take as little as a hundred years, or tens of thousands of years at most, and the further he went, the more difficult it would be to open up the immortal aperture, but if there was an elixir that matched the realm to help, this time could naturally be greatly shortened.

It's just that the refining of this kind of elixir not only requires tens of thousands of years of spirit grass as the main material, but even the auxiliary materials are very rare and expensive. And even if it is an experienced Didan master, if he does not go through dozens of attempts, the success rate is pitiful.

This is also the reason why only big sects or big forces can generally cultivate Di Dan masters.

At this time, Han Li was walking out of the Linchuan Pavilion near the gourd peak, came to the foot of the mountain, and walked into a golden heavy eaves hall.

This hall is closely connected with the large array that envelops the gourd peak, and it is the only entrance and exit of the entire gourd peak.

After verifying his identity, Han Li stepped directly into a teleportation array in the center, and as a burst of white light rose, he disappeared from the spot.

In a short time, he appeared in a large vermilion hall at the top of the peak.

The furnishings in the hall are no different from those in the market pharmacy, and they are also in the form of the front cabinet and the back grid, but there are obvious prohibitions on these grids with ground-level pills.

There were very few people in the main hall, except for the two deacon elders, there were only a few people wearing the costumes of the inner gate elders who came to buy the elixir.

Seeing Han Li come in, one of the middle-aged deacon elders with a slender figure and a kind face stepped forward and asked, "In the lower leaf Nanfeng, it's this Immortal Medicine Pavilion deacon, I don't know what your needs are?"

"It's raining hard, and I want to buy some pills to assist in cultivation. Han Li arched his hand and said.

"It turned out to be Li Daoyou, then I will recommend a few pills for Li Daoyou......" Ye Nanfeng smiled and said.

"I'm tired. Han Li nodded.

"With Li Daoyou's cultivation now, the most suitable Jingjin Pill is this 'Tongyuan Dan', there are ten pieces in each bottle, and only two hundred merit points are needed. If you have higher requirements for medicinal efficacy, then you will not be disappointed if you choose the 'Elixir of the Spirit', but the price of this pill is slightly higher, requiring a bottle of 500 merit points, which is also ten. Ye Nanfeng said.

Although Han Li had been mentally prepared, he was really shocked when he heard this price.

I had done three regular deacon-level tasks before, and now I have less than five hundred merit points on my body, and the price of these pills is really expensive.

"This elixir is really not cheap. Hearing this, Han Li said with a wry smile.

"That's natural, this Spirit Pill is in the entire sect, but only Master Huyan can refine it, and the quantity is very limited. Ye Nanfeng explained with a smile.

As soon as Han Li heard the title of "Master of Huyan", his mind couldn't help but flash the sloppy old man who wore a gray and white Taoist robe and kept drinking gourds all day long.

Could it be that this person is actually a high-level Earth Dan Master?

"Li Daoyou, if both are not suitable, this 'Chunlin Pill' is also suitable, the price is lower than the Ling Ling Pill, the medicinal effect is better than the Tongyuan Dan, but the cost performance is the highest. Ye Nanfeng saw that Han Li was a little distracted, and asked out loud.

"Dare to ask Elder Su, is there a pill for sale in this Immortal Medicine Pavilion?" Han Li suddenly asked.

"This ...... Could it be that Daoyou is planning to refine the pill by himself?" Ye Nanfeng was stunned for a moment when he heard this, and subconsciously asked.

"Oh, that's right, I happen to know a Di Dan Master who has just advanced, and he promised me that as long as I can provide Dan Fang and spiritual materials, he will be willing to help me try to refine the pill. Han Li said.

Ye Nanfeng listened, and there was a look on his face that wanted to speak and stopped.

Seeing this, Han Li knew that the other party should be trying to persuade himself that it was better to buy the elixir pill than to buy the elixir pill and let that person try it out.

"Both the Dan Fang Dao of Tongyuan Dan and Chunlin Dan are sold, only the Dan Fang of this Spirit Pill is not allowed to be sold without the permission of Master Huyan. Probably because of the deep words, Ye Nanfeng finally changed his words and said.

"But I don't know how many merit points do these two Dan prescriptions need?" Han Li asked.

"Tongyuan Dan's Danfang needs fifty merit points, and Chunlin Dan needs one hundred and fifty merit points. Ye Nanfeng replied.

Hearing this, Han Li looked hesitant as he pondered which Dan Fang would be more cost-effective to buy.

"Elder Li can look at the raw materials used in the two Dan recipes, and then decide which Dan recipe to buy. Seeing this, Ye Nanfeng reminded with a smile.

"Then there's work. Han Li nodded.

Ye Nanfeng's palm swept in the void, and after a flash of cyan light, a cyan book appeared.

He opened it, rummaged through it a little, and handed it to Han Li.

After Han Li took it, he checked it and found that what was recorded on it was the list of raw materials needed for Chunlin Dan.

"One fifty-thousand-year-old dragon grass, three five-thousand-year-old Broken Sea Flowers, a handful of windswept sand, and seven three-thousand-year-old Youluo Fruits......" Han Li pointed to the names and silently recited them one after the other.

He found that among the fifteen elixirs in total, there were very few ordinary elixirs, most of them were high-grade elixirs of a lot of years, and the least of them needed three thousand years.

"Elder Ye, I don't know how to sell the spiritual herbs in this Immortal Medicine Pavilion, do you also need to exchange merit points?"

"That's not necessary, except for some particularly rare elixirs that are too old and must be settled with immortal stones, other elixirs can be purchased with immortal stones or superb spirit stones. Ye Nanfeng shook his head and said.

"How many spirit stones do you need to purchase all the medicinal materials needed for this Chunlin Pill?" Han Li continued.

"Among them, the dragon grass as the main material needs to be settled with immortal yuan stones, the price is seven immortal yuan stones, and the rest of the elixirs add up to about two thousand top-grade spirit stones, of course, you can also use immortal yuan stones to settle. Ye Nanfeng said after a little hesitation.

Hearing this, Han Li couldn't help but secretly speak, if calculated at this price, he would spend all the Immortal Yuan Stones and Top-grade Spirit Stones on his body, and he would not be able to buy a few pairs of the elixirs needed for this pill.

As soon as he twisted the page with his fingers, he was about to turn it back, but Ye Nanfeng opened his mouth and reminded:

"Tong Yuan Dan's position is a little forward, and Elder Li should be able to see it if he turns a few pages forward. ”

Han Li flipped two pages forward as he said, and sure enough, he saw the list of elixirs that recorded Tongyuan Dan.

When his gaze fell on the "50,000-year-old candle Ling grass" on the first line of Danfang, his eyebrows raised slightly.

This medicine is the main material for refining Tongyuan Dan, and it is planted in the elixir garden in his cave mansion, and several plants have been cultivated before, and the years are basically the same, which is just right to use.

He continued to look at the more than ten auxiliary elixirs in the back, and he was not so lucky, all of them were elixirs that he had never planted.

"Then apart from the Candle Ling Grass, how many spirit stones do each of these elixirs need?" Han Li asked.

"If you remove the main medicine Candle Ling Grass, the other elixirs will require 1,200 top-grade spirit stones. Ye Nanfeng replied.

When Han Li heard this, he had a plan in his heart.

He bought back the pill this time, which was also the first time he tried to refine the Di Dan, and he didn't know how much elixir would be wasted, and it would definitely not be cost-effective to choose the Chunlin Dan Formula, which was more expensive in elixir.

"Then Tong Yuan Dan's Dan Fang. Han Li made up his mind and spoke.

"Okay, please give me the token. Ye Nanfeng said.

Han Li flipped over his hand and took out the Elder Token and handed it over, and after the latter took it, after deducting fifty merit points from it, he returned the rubbed Danfang and the token together.

"In addition, I also have to buy other elixirs needed to refine the Tongyuan Pill except for the Candle Ling Grass, and each one will cost ten copies. Han Li immediately took the Dan Fang, and after carefully examining it for a moment, he spoke.

With all the savings he had on him now, there was not much left to buy these elixirs.

After the transaction was completed, Han Li said goodbye, left Hulu Peak, and went straight back to the cave mansion.

......

Three months flew by.

During this period, Han Li had hardly ever been out of the secret room, and he had devoted himself entirely to the study of the Dan Fang, carefully pondering every step of its refining, meticulously deducing it in his mind, and invisibly doing this alchemy a thousand times.

Although he had already had a lot of experience in alchemy before, there were thousands of differences in the details of different pill ingredients in the refining process, and these differences were often important factors that led to the failure of alchemy.

Therefore, he thought about thoroughly understanding this page of Danfang before starting to refine it.

It wasn't until today that he finally decided to start trying to refine this Tongyuan Pill for the first time.

I saw that in its secret room, on the table behind the futon, there was an incense burner, which was lit with a long blue-gray incense, and a little red star was lit at the top, from which came out curling green smoke, exuding a faint fragrance that could make people's minds calm.

Han Li sat cross-legged on the futon with his back to the desk, closed his eyes and sat quietly for a long time, then slowly opened his eyes again, his whole mind was one, and there was no longer the slightest distraction.

On the ground in front of him, there was a purple copper furnace with a radius of a few feet, engraved with Taoist flame patterns and ancient runes, and a piece of cyan brocade next to it, on which were placed more than a dozen elixirs such as candle grass.

This Dan Furnace is something he got from the Mirage Beast Cave Mansion before, although the grade looks average, but it should be enough for the refining of this Tongyuan Pill now.
