After a few days, Zhang Yifan was disappointed.

The elixir of thousands of years is basically priceless, and he has run all over the medicine halls in Jinshan City, and basically none of them are sold, and even if there is, it is basically a barter, and it is difficult to trade successfully.

On the premise of not finding the corresponding Danfang, Zhang Yifan didn't want to take out the materials he cherished for an elixir that was likely to be impossible to refine.

As for the Jindan period pill formula, he received an ancient recipe called Zihui Yuan Dan, and it cost him 20,000 spirit stones.

Zihui Yuan Dan is a kind of elixir that improves mana in the middle stage of Jindan, and the effect of the elixir introduced in the pill is very good, and because the elixir naturally contains a purple poison, even the great master of alchemy cannot remove this purple poison.

Purple poison will gradually manifest itself after swallowing the pill, and it is also very difficult to remove from the body, requiring a lot of energy.

So gradually, no one cared about this elixir, and the pill was shelved and became an ancient prescription that was almost abandoned.

Moreover, the main elixir that refines this elixir is a spirit fruit named Purple Hui Fruit, and the monk who sold the pill originally had some thoughts on refining this pill, but after inquiring for a long time, he didn't know the origin of this spirit fruit, and finally he died and sold this ancient recipe to Zhang Yifan at a low price.

Zhang Yifan also had never heard of what kind of spirit fruit the purple spirit fruit was, and there was no record in the "Qingling Sanren Elixir Record" and other pharmacopoeias, but this did not prevent him from collecting the pill first.

This Danfang originally wanted to sell 30,000 spirit stones, but Zhang Yifan bargained, and finally sold 20,000 spirit stones. Although it is still a lot of these spirit stones to buy a nearly abandoned Danfang, it is nothing to Zhang Yifan's current net worth.

In the eyes of others, the value of the pill with natural erysipelas is low, but it can play a very significant effect here.

In addition, Zhang Yifan obtained some early Jindan pills through auctions and exchange meetings, and the prices of these Jindan early stage elixirs to improve mana were not low, even if Zhang Yifan now had a lot of spirit stones, he still felt very distressed.

Moreover, the effect of these pills is very average, and the purchase of these pills is a helpless move at present, and Zhang Yifan's mood of wanting to refine the pills by himself is even more urgent.

The pills he bought now were barely enough for him to cultivate for a period of time after being refined by the mysterious spring water, so he didn't have to worry about the fact that there were no pills to use for the time being.

Now Zhang Yifan rarely collects waste pills, first, the risk is relatively large, and it is often easy to attract the curiosity of other people, and second, almost all the waste pills are below the Jindan period, and the number of waste pills above the Jindan stage is very small, and the owner of the pill often does not take it out for sale for the sake of secrecy.

After entering the Jindan stage, the problem of cultivation became a problem for Zhang Yifan, and only now did he really understand the reason why there were so few Yuan Infant Stage cultivators.

Most of the monks who have entered the Jindan stage need to rely on pills to improve their cultivation realm faster because of their qualifications, so that they can cultivate to the Great Perfection realm of the Jindan stage when Shouyuan enters the end of the stage and impact the Yuanying realm.

The lifespan of a monk in the Jindan period is generally about 400 years, and generally if the monk has not entered the Great Perfection realm of the Jindan stage before the monk is 300 years old, it means that it is difficult to go further.

By the end of the monk's life, his blood and qi will decay, his energy will be insufficient, and even his soul will degenerate and decay.

The lack of elixir means that the time required to cultivate will be longer, and the time for breaking through the bottleneck will be less, so that the advanced Yuan infancy stage will be even more slim.

This is also an important factor in why infant monks are so scarce.

However, this matter is not in a hurry, Zhang Yifan has a very clear understanding of this, first accumulates the foundation, and then accumulates it steadily.

Next, Zhang Yifan began to collect some information about the Yin Thunder Valley, and at the same time looked for information about the Xuanyin Evil Thunder Vine.

After spending a lot of spirit stones, Zhang Yifan got some information about Yin Thunder Valley from the Tianji Tower in Jinshan City, which was more specific than what he knew before.

Yin Thunder Valley is located in the depths of the Great Wilderness, near the edge of the icy region, and is rarely visited.

The area of Yin Thunder Valley is not small, twisting and turning, thousands of miles in length and horizontal.

Yin Thunder Valley is famous for the powerful Yin Thunder that often rains down in the sky, and there are many Yin Thunder attribute demon beasts in the valley, which are generally extremely difficult and powerful.

There are many demon beasts above the seventh level in the valley, and it is even rumored that there is a ninth-level Dacheng Thunder Demon in the depths of the Yin Thunder Valley, as for the existence of the Yuan Infant Demon King above the tenth level, it is unknown.

However, fortunately, Zhang Yifan learned from the intelligence of Tianji Tower that it was not necessary to enter the Yin Thunder Valley to go deeper, and someone had previously found traces of the Thunder Demon Ape from two or three hundred miles away from the entrance of the Yin Thunder Valley, and it was also a seventh-level Thunder Demon Ape.

The area where the Thunder Ape lives generally has the Xuanyin Thunder Vine, and if there is a seventh-level Thunder Demon Ape, it must be at least eight hundred years old.

At that time, the man also wanted to look for the Xuanyin Evil Thunder Vine, but was soon discovered by the Evil Thunder Demon Ape, and was defeated in the battle, and retreated with serious injuries. After that, the monk stopped looking for the Xuanyin Evil Thunder Vine and sold the news to the Tianji Tower.

In this regard, Zhang Yifan suspected that the person might be the real person of Jiuhe.

After getting this news, Zhang Yifan was relieved a lot, but he didn't think that he was at ease, and he was still collecting some useful news before leaving.

With the help of Yinzhai, Zhang Yifan participated in an exchange meeting of Jindan monks held by the Qin family, a local immortal cultivator in the Eastern District.

In a secret place of the Qin family, nearly ten Jindan monks gathered together, most of them covered their faces, and an exchange meeting was going on at this time.

"Welcome all fellow Daoists to participate in this exchange meeting held by my Qin family, according to the old rules, the old man will first show the treasures that my Qin family is going to exchange this time, as well as some treasures that need to be exchanged. A mild-faced Jindan monk said loudly to everyone.

"Haha, Qin Daoyou, this time you have come up with something good, let Hu open his eyes. A huge fat monk said with a big grin.

"Hehe, Hu Daoyou's Xuanhu strength seems to be refined again, and this time the treasure may be of interest to Hu Daoyou. The monk surnamed Qin said.

"Oh, then Hu will wait and see. The monk surnamed Hu had a gleam in his eyes, and said with some interest.

"Okay, no further ado. A three-thousand-year-old meat sunflower is the best with thirty-six meat sunflower seeds, and the nine-grade attack magic weapon Tiger Roaring Golden Knife is exchanged for a nine-grade defense magic weapon of the same level or three golden pills to break through the bottleneck in the middle stage. ”

"What! It turned out to be a three-thousand-year-old meat sunflower, a thousand-year-old meat sunflower can increase the power of a tiger by eating a meat sunflower seed, and a three-thousand-year-old meat sunflower is afraid that one will increase the power of three to five tigers, this kind of miraculous medicine can't be imagined that Qin Daoyou can get, it's really a good opportunity." ”

"It turned out to be a magic weapon of pure attack like the Tiger Roar Golden Knife magic weapon, and it has reached the ninth rank, the attack power must be extraordinary, if I get it, the strength will be increased by at least three percent. ”

The treasure mentioned by the monk surnamed Qin made the hearts of the Jindan monks present very hot.

Zhang Yifan was also very interested in these two treasures.

He had heard of the meat sunflower before, it was a miracle medicine that was born and raised, and when it matured, it would contain meat sunflower seeds, and the number of more than 30 pieces could be called the best, and the most seemed to be more than 100 pieces.

Monks can increase their physical strength by eating meat sunflower seeds directly, and they can also increase their physical strength slightly, which is very rare.

The older the flesh sunflower, the better the effect, of course, if the monk himself is stronger, the role of the meat sunflower seed will be weaker, and it is mutual.

Zhang Yifan estimated that the three thousand years of meat sunflower seeds would not have much effect on his current physical body improvement, but he wanted to study this medicine, so he was more interested.

He also coveted the Tiger Roar Golden Knife magic weapon of the ninth grade, after all, he currently did not have an attack magic weapon in his hand, and one more piece would give him one more choice, and it could also be used for refining research.

But he didn't have the mid-stage Jindan pill that broke through the bottleneck in his hand, and he was reluctant to exchange it for the nine-rank Zhenshen Tower, so he had to see if he could buy it with spirit stones at that time.

Someone soon broke the situation, and the fat monk pulled out a green bead that exuded a good aura.

"This is a nine-grade defensive magic weapon green yarn bead, and the defensive power is extraordinary. Qin Daoyou, do you think it's okay?"

The monk surnamed Qin took the green gauze beads, looked at them carefully, and found that the defensive power was indeed good, and he was very satisfied.

"Hu Daoyou, this nine-grade magic weapon is good, I don't know what kind of treasure you want to exchange. ”

Qin Daoyou asked knowingly, I'm afraid you have been eyeing Hu's green gauze beads for a long time. Give the Tiger Roar Golden Knife to Hu, and you have to compensate for 100,000 spirit stones, I won't talk about more. The monk surnamed Hu rolled his eyes and said unceremoniously.

"Hehe, that's easy to say. ”

The two quickly completed the exchange, and the atmosphere was harmonious.

Soon the meat sunflower was also replaced, and a monk took out three Yanyuan Pills, and the monk surnamed Qin was immediately overjoyed and immediately changed.

Yan Yuan Dan is a very famous pill in the middle of Jindan, which stimulates a force of Yan Yuan by igniting the mana in the body, which is very effective for breaking through the bottleneck, although there will be some backlash, so that the monk's vitality is damaged, but this backlash is nothing at all for being able to break through the bottleneck.

Each Yanyuan Pill is worth a fortune, at least more than 100,000 spirit stones, and there is no market.

The two treasures were exchanged out, which made Zhang Yifan feel a little pity, but he was not in a hurry to get angry, and he had a lot of good things on him.

However, his understanding of these Jindan period monks has increased a lot, and it turns out that many Jindan stage monks have a good background, and they should not be underestimated.

The rest of the exchange did not go well, as many monks sought something that was either too obscure or too unequal in value, and few of them reached their own intentions.

These are also some of the drawbacks of the exchange meeting, and if you don't prepare thoroughly, you are likely to go home.

Soon it was Zhang Yifan's turn.

"If you want to exchange or buy the Jindan period Danfang, any one or message of the Golden Centipede Flower, the Green Snake Flower, the Poison Ha Flower, the Red Tail Flower and the Yellow Sand Flower that is more than five hundred years old must be a poisonous flower that grows next to the seventh-level demon beast. If you want to buy the Xuanyin Evil Thunder Vine or specific news, you can exchange it for the best Ming God Pill or Spirit Stone. Zhang Yifan said three needs in one breath.

After three breaths, seeing that everyone didn't react, Zhang Yifan sighed, and when he was about to give up, someone sent him a message.

"I don't know why Daoist friends need green snake flowers?"

Zhang Yifan swept around and found that it was a blue-clothed monk who had transmitted his voice to him, and Jindan was an early cultivator.

"It's inconvenient to disclose below, whether Daoyou can have green snake flowers, and if you sell them, you can put forward conditions. Zhang Yifan replied.

"I don't have a green snake flower in my hand, but I know where there is a seventh-level three-headed snake demon beast, and there should be a green snake flower near it. The Bluefriar spoke.

"Daoyou directly said the conditions. ”

"I want Daoyou to help deal with that blue-veined three-headed snake, and when the time comes, the green snake flower will be yours, how about being a reward for Daoyou?"

"If that demon beast is in this great wasteland, Daoist friends will act in the near future, and there will be some time to participate in the future. Zhang Yifan replied.

"Don't worry, that demon beast is not far from Jinshan City, and it can be acted on in the near future. ”

"Okay, we'll talk about it after this exchange meeting. ”

After that, the blue-robed monk said no more.

Seeing that the other monks did not respond to his request, Zhang Yifan then retreated.

Soon it was the turn of the other monks.

Towards the end of the exchange meeting, the words of a monk who was as thin as a monkey attracted the attention of Zhang Yifan and other new monks who participated in the exchange meeting.

"There is a secret news about Yin Thunder Valley for sale, only 100,000 spirit stones. ”

"Yuan Daoyou, aren't you giving up, your news caused a lot of trouble at that time. The monk surnamed Qin said with some displeasure.

"Qin Daoyou, this news is my master's personal experience, it is absolutely true, and I dare to guarantee it. Previously, the person had not been able to reach that place at all, not because the information provided by Yuan was wrong. ”

"Then you can sell this news to Tianji Tower, why sell it here?"

"Tianji Tower only allows me to sell it once, how can I agree to such a lossy deal. ”

"Then it's up to you, if there is a Taoist friend looking for trouble, the old man will not come forward. ”

"Qin Daoyou, I don't know what kind of news is so mysterious?" Zhang Yifan's heart moved, and he asked with some curiosity.

"Li Daoyou doesn't know, this is actually a legend about Yin Thunder Valley. The monk surnamed Qin glanced at Zhang Yifan, and then said.

"Oh? ”

"Since so many Daoyou are interested, let's talk about it, Yuan Daoyou's secret news is also about this legend. The monk surnamed Qin said, and then began to talk about the legend about the Yin Thunder Valley.

It is rumored that a long time ago, there was no Yin Thunder Valley in the Great Wilderness, and it was rumored that a mighty Yin Thunder suddenly fell from the sky, and a wasteland was forcibly split into a Yin Thunder Valley, and there were constant Yin Thunder Valleys in the sky all year round, becoming a desperate place.

As the saying goes, the extremes of things must be opposed, and the entire Yin Thunder Valley was filled with Yin Thunder spiritual power, giving birth to a very pure wisp of Yang Thunder spiritual power. This wisp of Yang Thunder Spiritual Power and a very pure wisp of Yin Thunder Spiritual Power of Yin Thunder Valley were combined by chance, attached to a ball of heavenly fire, and finally formed a mass of purple thunder true flame.

The Purple Thunder True Flame is one of the Heaven and Earth Spiritual Flames, a kind of thunder-attribute spiritual flame, which only exists in the classics and has never been seen by anyone.

According to the classics, as long as the Purple Thunder True Flame is mastered, the monk can not only cultivate the Thunder Spell and the Flame Spell at the same time, but also greatly increase his strength, but also have a great benefit in resisting the Thunder Tribulation.

As soon as this news was born at that time, it immediately spread throughout the Great Wasteland, and even other states in the Chu State had heard about it, and many Jindan stage monks and even Yuan Infant stage monks rushed to the Yin Thunder Valley to find out the true flame.

But no one had ever seen the Purple Thunder True Flame, but because many monks gathered in the Yin Thunder Valley, it seemed to trigger the Heavenly Might, and the Heavenly Yin Thunder suddenly fell in the Yin Thunder Valley.

Many of the monks were reduced to ashes under the attack of the thunderbolt, and only a few escaped by chance.

From then on, no one dared to gather people to explore the Yin Thunder Valley, and the matter of the True Flame was completely extinguished, and no one cared about it.

However, this happened before the establishment of Jinshan City, ten thousand years ago, and the truth of the matter has long been annihilated in time, and no one knows how.

Yin Thunder Valley has now also become a paradise for Yin Thunder Demon Beasts, which is very dangerous, and few monks enter it. Moreover, it is said that entering the Yuan Infant Stage Monk will also trigger the Heavenly Yin Thunder Attack, so few people know about the situation in the depths of the Yin Thunder Valley.

The Purple Thunder True Flame has become a legend in the Yin Thunder Valley, although occasionally there are monks who are interested in exploring it, but they only look at the periphery of the Yin Thunder Valley, and they dare not go deep into it.
