For this legend, Zhang Yifan will be skeptical.

His previous intelligence search had also unearthed the legend of how the Valley of the Yin Thunder was formed.

Although it is different from this Purple Thunder True Flame, the beginning is generally the same, it is the Heavenly Yin Thunder that splits a part of the Great Wasteland to form the Yin Thunder Valley.

He didn't believe this, what kind of heavenly thunder could hit thousands of miles into a valley, such a great force could not be imagined.

As for the Purple Thunder True Flame, he had two points of belief.

The yin pole must be yang, and the object pole must be opposed, he himself has practiced the "Nine Yin and Nine Yang Thunder True Formula", and his understanding of the yin and yang instruments is somewhat profound, everything in the world has two sides, mixed with each other and opposed to each other, mysterious and unpredictable.

Maybe it is really possible that there is such a thing in the Yin Thunder Valley, so that the Yin Thunder Aura and the Yang Thunder Aura can combine with the Heavenly Fire to form a wisp of Heaven and Earth True Flame.

The formation of the true flame is strange, not to mention, some are condensed by the essence of the fire, some are the flame of the spiritual object, and some are even the demon fire in the body of the fire attribute demon beast after the death of the demon beast turned into a true flame.

Zhang Yifan, as the great master of refining, is very eager for the true flame, and he has been paying attention to it all the time, coupled with the introduction of the true flame in the Tiangong Silver Codex, the refining method, etc., Zhang Yifan knows a lot more about the true flame than ordinary monks.

So he was now interested in the secret that the monk surnamed Yuan said, but it was indeed too expensive to buy a news of 100,000 spirit stones, and it seemed that this news was not the only one, and the monk surnamed Yuan could also sell it to others, which made him hesitate for a while.

"Ladies and gentlemen, just now Qin Daoyou has already told the legend of Yin Thunder Valley. However, the following news is about the Purple Thunder True Flame, this thing is absolutely true, my master saw the Purple Thunder True Flame in the Yin Thunder Valley a few years ago, but he fell soon after he encountered an accident. If anyone gets the news, there's a good chance they'll be able to find the True Flame. Rest assured, I only sell this news once a year, and I am bound by each other's intentions and demon oaths. Seeing that everyone seemed to be hesitant, the monk surnamed Yuan spoke.

"This fellow Daoist, I am a little interested in what you said about the Purple Thunder True Flame, but can you swear with your heart demon that what you said is true? Zhang Yifan said.

"No, I can't. The Purple Thunder True Flame was not verified by his own eyes, and there was no guarantee that it must be true, this was inferred from what the lower master saw, and the Purple Thunder True Flame would be known when you went to the place in the Yin Thunder Valley. The monk surnamed Yuan shook his head and said.

Seeing the monk surnamed Yuan say this, Zhang Yifan's only interest was also wiped out, and he shook his head and stopped responding.

Although he was interested in the True Flame, he would not be wronged.

No one would pay 100,000 spirit stones because of the frivolous words of the monk surnamed Yuan, even if it was 50,000 spirit stones, it would be expensive.

If there really is a Purple Thunder Spirit Flame, even if it is a million spirit stones, many people are vying to buy this news.

How precious the True Flame is, this is a treasure that even the Yuanying Monks covet, once it is cultivated, it is equivalent to an additional fire attribute supernatural power.

Moreover, the True Flame has a very great benefit to alchemy refining tools and so on.

It's just that the true flame in the world is too rare, most of the rumors are false, and many people think that it is a true flame but it is actually just a fire attribute treasure. Zhang Yifan also understands this, since the monk surnamed Yuan does not dare to swear, the possibility that this matter is true is very small.

In the end, the other monks present were not interested, and the monk surnamed Yuan returned in disappointment.

The legend of Yin Thunder Valley came to an end, and soon the exchange meeting ended.

Zhang Yifan and the blue-clothed monk sat down in a tavern in Jinshan City that received immortal cultivators.

"In Xia Huangqi, I don't know where the name of Youzun comes from?" asked the blue-clothed monk.

"Under Li Yuan, it is a loose cultivation. Daoyou said earlier that he knew about a seventh-level Dacheng blue-veined three-headed snake demon beast, could he be sure?" Zhang Yifan said straight to the point.

Huang Qishen glanced at Zhang Yifan a few times, which made Zhang Yifan a little baffled.

Then Huang Qi said: "This matter is true, and it has been investigated clearly. Although the blue-veined three-headed snake was not seen with his own eyes, judging from some traces, it should be a seventh-level Dacheng demon beast, and it had not reached the eighth level. ”

Seeing that Huang Qi was full of confidence, coupled with the induction of Miaolian's secret technique, he knew that the other party was not lying, Zhang Yifan believed it a little.

The strength of the blue-veined three-headed snake is very powerful, three heads can cast spells at the same time, and it has rough skin and thick flesh, and it is also a very prominent existence among demon beasts of the same level.

A seventh-level Dacheng blue-veined three-headed snake can steadily suppress the monks who don't have the best magic weapon in the early stage of Jindan, Zhang Yifan didn't suspect that the other party had any conspiracy to cooperate with him, but finding him so easily also made him a little wary.

With Zhang Yifan's current strength, he is not afraid of a monk of the same level, but he doesn't want to cause trouble casually, after all, he is now a high-level monk in the Burning Sky Valley.

"How does Huang Daoyou want to cooperate? Are there any other people?" Zhang Yifan asked.

"I also have a younger sister who will act with us to build the foundation for the Great Perfection. When the time comes, after killing the blue-veined three-headed snake, the green snake flowers will all return to the Daoists, and the corpses of the demon beasts will also return to the Daoists, as long as the snake gall and the demon pill of the snake demon, as for other things, when the time comes, according to their respective contributions, what do you think?" Huang Qi discussed.

"It's fair, Ling Mei's cultivation is a little low, and I don't have the responsibility to protect her thoroughly, can you understand this?" Zhang Yifan said directly, hearing that there were monks in the foundation building period involved, and he was a little displeased.

"There is no need to worry about this, although my sister's cultivation is lower, her ability to save her life is not bad. Huang Qi nodded and said.

The two then discussed some details, roughly explained their respective methods, and agreed to meet outside the north gate of Jinshan City in three days.

To Zhang Yifan's surprise, the blue-clothed monk in front of him, who was not amazing, turned out to be almost a monk with a double cultivation of the Dharma body and body.

Most of the methods he explained were close-quarters, which made Zhang Yifan a little impressed.

Bidding farewell to Huang Qi, Zhang Yifan prepared some things to go to Yin Thunder Valley, and then meditated and waited for three days to act.

......

East District, Qin Family Secret Hall.

"Senior Qin, do you have news here?"

"Well, the person your master asked the old man to inquire about earlier appeared in Jinshan City, and he must be going to Yin Thunder Valley soon. ”

"Oh, is it, can Senior Qin track down that person?"

"Hmph, the old man just asked your master about this person, how could he do such a thing that ruined his reputation. ”

"Don't blame the seniors, it's offended, please don't blame the seniors. ”

"For the sake of your master's face, forget it this time, and next time, you won't appear in Jinshan City. ”

"Yes, yes. ”

"You tell your master, this kid is not easy to deal with, his strength is extraordinary, although he has just advanced to the Jindan stage, but it feels very difficult to deal with the old man. And if you don't say who this person is, the old man can guess one or two, he is playing with fire. That person's sect is not as good as it used to be. ”

"My master's intentions are not clear, and I don't want this person's life. ”

"Alright, there you go. ”

.....

Three days later, Zhang Yifan went to a remote place more than ten miles outside the north gate of Jinshan City as agreed.

At this time, two monks, a man and a woman, were already waiting.

"Huh, is it you?" Zhang Yifan was a little surprised when he saw the nun's face.

"Hehe, Senior Zhang hasn't seen you for a long time, I said goodbye to Wuji Island before, and the younger generation has to thank the seniors for the Blood Dragon Pill Danfang, which helped the elder brother, and finally succeeded in condensing the Golden Pill. ”

The female cultivator is Huang Shan, who had a deal with Zhang Yifan before, and she was deeply impressed by this female Zhang Yifan.

"I didn't show my true face before, I don't know how the yellow fairy found out my identity?"

Whether it is now or before, Zhang Yifan has changed his face, so it is a little strange why the other party can recognize his identity.

"Senior, this time I collected the green snake flower in order to refine the five flowers. Huang Shan said with a smile.

"Yes, do you also know that the five flowers?" Zhang Yifan was really surprised, it seemed that the other party really knew a lot about alchemy.

"The "Huang Yuan Pharmacopoeia" that my predecessors bought from Zheng Sui's hand before is the ancestral heirloom of my Huang family. And the feat of the predecessors on Wuji Island has actually spread all over the island, and the juniors and brothers are thunderous about the names of their predecessors. Everyone knows that it was Burning Sky Valley Zhang Yifan and Zhang Da Grandmaster who got rid of that Wu Dalong. Huang Shan said.

"And this time, the seniors collected those kinds of poisonous flowers, and the juniors guessed that the seniors must have been refining the five flowers. The rest doesn't need to be said by the juniors, and the seniors also understand. ”

"I see. Since this is the case, then I will no longer hide it, but my identity is a little special, and I hope that the two of you will keep it a secret. Zhang Yifan did not deny it, and said frankly.

"That's nature. Huang Shan nodded and said.

"What about this "Huangyuan Pharmacopoeia"?" Zhang Yifan thought that the two wanted to ask him for this pharmacopoeia.

He actually took a big advantage when he bought this pharmacopoeia, but now if the other party wants it, he doesn't plan to return it, Wuhuasan is very important to him, and he can't copy the Danfang before refining it.

"Since the seniors have obtained this pharmacopoeia, it is naturally the seniors', and the seniors can rest assured that my brother and sister will not be covetous. Besides, we have studied the pharmacopoeia almost as well. Huang Shan said happily, which made Zhang Yifan have a good impression of the two people in front of him.

When Huang Shan spoke, Huang Qi remained silent, mainly Huang Shan, which made Zhang Yifan a little different.

"Huang Daoyou, please lead the way, I don't know where the blue-veined three-headed snake is?"

"It's about five hundred miles away from Jinshan City, Zhang Daoyou came with me. Huang Qi said.

The trio then fled at great speed towards the area where the three-headed snake was located.

The three-headed snake is hidden in a hidden cave, and there are many monsters nearby, which is difficult to detect.

Huang Qi was also chased by a group of poisonous bats by chance, and when he was cornered and ran away, he found a cave hidden under the moss.

When it ran to the cave, the poisonous bats retreated on their own, allowing it to escape.

Huang Qi found some traces when he observed the cave, and judged that this was a cave of a blue-veined three-headed snake, and after several investigations, it was finally confirmed that it was a seventh-level demon beast.

He felt that with his current strength, he couldn't deal with this demon at all, and he was a little uneasy to find outsiders.

By coincidence, Huang Qi met Zhang Yifan.

As soon as Huang Qi saw Zhang Yifan seeking five kinds of poisonous flowers, he knew his identity.

Zhang Yifan's reputation is outside, his strength is strong, and his reputation is very good, he has heard his sister say it before.

After some thought, he finally decided to cooperate with Zhang Yifan.

Along the way, under Huang Shan's thread, the three of them communicated very happily, especially after they found out that each other had a deep knowledge of alchemy, and the conversation was even more pleasant.

The distance of more than 500 miles was soon reached, and Zhang Yifan was still a little unsatisfied.

This exchange has made him gain a lot, and he has a new understanding of the idea of alchemy, you must know that he is now a great master of alchemy.

Moreover, the brother and sister have a lot of research on ancient prescriptions, and they can find the corresponding current drug names or elixirs with similar effects for some obscure ancient medicines.

Zhang Yifan wanted to sort out all the Dan prescriptions in the "Huang Yuan Pharmacopoeia", Huang Shan said that he and his brother had only mastered part of it, and the three agreed to communicate and talk about it after the matter was done.

Although a seventh-level blue-veined three-headed snake is powerful, it is not very powerful in Zhang Yifan's eyes, and he is confident that it can be solved smoothly.

On the way into the snake cave, Zhang Yifan and the others encountered the group of poisonous bats again.

There are about a hundred poisonous bats in this group, and the leader of the bats is a seventh-level demon beast, and the rest are fifth- and sixth-level demon beasts.

Huang Qi was shocked and wanted to take the two of them to escape quickly, but Zhang Yifan signaled not to.

He directly sacrificed the Heavenly Ten Thousand Silk Banners, and at the same time used the Yin and Yang Decree to summon Xiao Zi, Xiao Bai, and Xiao Hei to meet the enemy.

Capture the thief and capture the king first, Zhang Yifan showed a very fast body, quickly approached the bat leader, and then directly used the soul shaking secret technique to shake him out of his mind, and then used the heavenly ten thousand silk banners to restrain him.

Xiao Zi directly bit the bat leader to death and absorbed his poisonous demon blood, which made his venom more toxic.

The whole process was no more than a breath, and the Huang Qi brothers and sisters were dumbfounded.

As soon as the leader died, the remaining poisonous bats lacked leadership, and their attack power was greatly reduced, so there was no need to worry.

Zhang Yifan's three spirit beasts quickly wiped it out. He collected the bodies of these poisonous bats and prepared to leave them for the three-star demon worms. These little creatures can't wait to devour the flesh of these poisonous bats.

Originally, Zhang Yifan also planned to let Xiao Zi absorb the poisonous demon blood of these poisonous bats, but Xiao Zi was not interested in the poisonous blood of the fifth or sixth level poisonous bats, so Zhang Yifan gave up.

Zhang Yifan's performance shocked the Huang Qi brothers and sisters, and their tone became more and more polite, faintly regarding Zhang Yifan as a senior.

Although Zhang Yifan is low-key now, he doesn't have to be as cautious as before, and there is nothing to hide from showing his strength this time.

Huang Qi's information was not wrong, the blue-veined three-headed snake in that cave was indeed a seventh-level demon beast.

However, there was one thing he was negligent, because the three-headed snake was hatching offspring, so it had been hiding in the depths of the cave and did not appear.

This time, after the three of them broke into the cave and went deeper, the blue-veined three-headed snake desperately attacked the three of them in order to protect the snake egg.

In order to keep the body of the demon beast intact, and also to save Huang Shan, who was in danger under the attack of the blue-veined three-headed snake, Zhang Yifan directly sacrificed the blood-drinking knife.

The power of the blood-drinking knife that absorbed Zhang Yifan's two-percent essence blood was almost to the level of a seven-grade magic weapon, and the two snake heads of the blue-veined three-headed snake were cut off with a single blow.

The last snake head was also quickly cut off under the joint attack of Zhang Yifan and Huang Qi.

It didn't take much effort for the three of them to kill this ferocious monster.

According to the agreement, Zhang Yifan got the body of the demon beast, and the snake gall and the demon pill were given to Huang Qi. In addition, Zhang Yifan also harvested five green snake flowers, all of which were more than a thousand years old, and the harvest was full.

For the snake egg, Zhang Yifan gave up to the Huang Qi brothers and sisters, on the condition that he would match some of the pills in the "Huang Yuan Pharmacopoeia" that he had not yet dispensed.

The Huang Qi brothers and sisters naturally happily agreed, and gave Zhang Yifan most of the pill formulas, which also included another piece of Jindan early stage Dan prescription Huang Chan Qiong liquid.

In this way, in the "Huang Yuan Pharmacopoeia", Zhang Yifan only has one Jindan period pill left, and the Huang Qi brothers and sisters didn't figure it out, but they only knew the current names of some ancient elixirs, and they all told Zhang Yifan.

In the end, both sides were happy with the result.
