Zhao Feiyu rubbed his chin and began to walk along the wooden platforms.

For him, those alchemy exercises are far more precious than those so-called pills, if he can master some alchemy techniques. It is far more valuable than having an elixir, and it can also promote Zhao Feiyu to increase his cultivation.

There weren't many monks in the pavilion on this floor, and the pavilion looked a little empty. The quiet environment is somewhat similar to what a library looks like in the real world.

At this moment, Zhao Feiyu is like wandering in a library in the real world. Quietly pick out your favorite books.

Zhao Feiyu skipped those spell jade slips one by one. and muttered about their introductions, but those introductions seemed a little mediocre, and for Zhao Feiyu at this moment, they didn't have much attraction to him.

Although Gu Xuan didn't transmit many spell means to Zhao Feiyu, just those few divine soul methods and cultivation methods were enough to be amazing, as well as the exercises that could convert the aura of heaven and earth into aura flames to refine the elixir.

Obviously, Gu Xuan must have been extremely powerful before he existed like this. It is even very likely that he is at the peak of this star, but because of the huge trauma he has suffered, only a wisp of soul thought is left in this body. But he still remembered his many methods.

According to Gu Xuan's words, he had too many methods that were not suitable for Zhao Feiyu's cultivation, because Zhao Feiyu's cultivation was too weak to withstand the pressure of cultivating those spells.

It's like a primary school student learning calculus, and it's extremely difficult. And Gu Xuan's methods are more like elementary school students learning quantum mechanics. I can't even understand the most basic quantum equations, let alone learn the vastness of quantum mechanics.

Even Gu Xuan's hands did not have exercises suitable for Zhao Feiyu's cultivation, and the Zhao Clan's Invincible Creation Skill was a mental method created by Gu Xuan specifically for Zhao Feiyu, which was suitable for Zhao Feiyu's cultivation.

At the moment, those exercises seemed to Zhao Feiyu to be unremarkable. It doesn't have much traction.

After searching for a long time, Zhao Feiyu suddenly stopped his steps.

"Cuiwei Alchemy ......" Zhao Feiyu softly pronounced out the name of this spell, "Attract the aura of plants and trees between heaven and earth to turn into aura flames to quench the elixir, and the aura of plants and trees turn into aura flames." It is possible to obtain the most essence and the most complete part of the herb without harming the nature of the herb itself, and to refine the purest elixir......"

And at the bottom of that exercise, there is a line of small characters, which is the price of this Cuiwei alchemy, eight thousand contribution points or eight hundred spirit stones. You can exchange for Cuiwei Alchemy.

"These exercises are really cheap, and they are not as valuable as the cheapest pills on the first floor." Zhao Feiyu couldn't help but sigh when he saw the price of Nacui Wei's alchemy.

According to the description of Cuiwei's alchemy, such alchemy methods are like Zhao Feiyu's alchemy methods in the Spider Demon Beast Valley, but all that Zhao Feiyu induces is the aura between heaven and earth, and what Cuiwei alchemy wants to attract is only the purest grass and wood aura.

Obviously, Gu Xuan's alchemy spell didn't know how high it was to be compared to this Cuiwei alchemy.

However, Gu Xuan's alchemy methods were too amazing, and Zhao Feiyu didn't want to be exposed in front of other monks, so as not to cause a disaster.

According to the description in the introduction, the pill refined by the Cuiwei alchemy technique was very similar to the pill refined by Zhao Feiyu using the yellow clay furnace, and if Zhao Feiyu peddled that extremely pure herb and wood pill in the future, it would definitely not arouse the suspicion of others.

This Cuiwei alchemy technique is undoubtedly one of Zhao Feiyu's best disguises. Never arouse the suspicion of others.

Zhao Feiyu had already made up his mind to buy the Cuiwei Alchemy Technique, so he walked towards the easternmost side according to the rules of the first, second and third floors.

But there was nothing but a row of wooden platforms on the easternmost side, and there were no platforms for buying and exchanging.

"Young man, are you looking for something?" An enthusiastic voice thought beside Zhao Feiyu.

Zhao Feiyu hurriedly looked at the side. I saw that it was an old man with gray hair, and he was also one of the monks who selected alchemy spells here.

"Uh, I'd like to ask how to buy the alchemy spells here?" Zhao Feiyu asked with a smile.

"Are you choosing? After the alchemy spell you want to purchase, just pour a wisp of your soul thoughts into the formation under that exercise, and then there will naturally be a monk from the Yuan Treasure Pavilion to explain to you the general effect of the exercise, the way you cultivate, and you will naturally understand it at that time. If you agree, press your status ring on the wooden platform and your contribution points will be automatically deducted. The gray-haired monk explained to Zhao Feiyu.

"Okay, okay, thank you." After Zhao Feiyu thanked the old man, he returned to Cuiwei Alchemy, before the wooden platform.

The gray-haired monk followed.

"Young man, do you want to buy this Cuiwei Alchemy?" The gray-haired old man couldn't help but be a little stunned when he saw Zhao Feiyu stop in front of the wooden platform where the jade slips of Cuiwei's alchemy were placed, so he asked.

Zhao Feiyu nodded slowly, "I think this exercise is still very good, at least looking at this description, I feel that it is still a very good exercise." ”

When the gray-haired monk heard Zhao Feiyu's words, he couldn't help but slowly shook his head, "Wrong, young man, this Cuiwei alchemy, but there is no high-grade spell, it is not even a Xuanpin spell." Now that you are in the cultivation of mortals, it may not take much time to step into the Xuan Realm, you are not cultivating such a spell that does not even have the quality now. In the future, it will greatly affect your cultivation path, and not only will it not bring any help to your path. Instead, it will slow down your cultivation speed and pull you back. ”

"And as far as I know, this Cuiwei alchemy has a huge flaw, and the monks of the current world should not be able to practice such exercises." The gray-haired monk continued.

"Huge flaws?" Zhao Feiyu asked.

The monk with the hair skateboard nodded slowly, "yes, you should see it." What is said in this exercise is to use the spiritual energy of the plants and trees between heaven and earth as one's own spiritual energy flame to refine the elixir. First, although there are many monks with spiritual veins, there are indeed very few monks with spiritual veins of the nature of plants and trees, and they are extremely rare. And those cultivators of the grass and tree spirit veins are extremely close to the grass and wood people in the heaven and earth, and they can be said to be excellent candidates for alchemy, and even more important than a powerful divine soul in a sense. But any monk who has a spiritual vein close to the way of plants and trees, Wuyi is not the best disciple of the alchemy line among the various sects. It will be cultivated with all its might in the middle gate. It can be said that it is the pride of the sky. ”

"Do you have to be a monk with a grass and tree spirit vein to be able to refine the Cuiwei alchemy?" A look of doubt appeared on Zhao Feiyu's face, and he couldn't help asking.

The gray-haired monk paced slowly with his hands behind his back.

"No, no, ordinary monks can also practice Cuiwei alchemy, but you have to know this Cuiwei alchemy. The aura flame used. It is an aura flame made of the aura of the plants and trees between heaven and earth. And the aura between heaven and earth is extremely complex. A lot of spiritual energy is mixed together, and only by diving into the heart and using one's soul power can we strip out the purest spiritual energy that is mixed between heaven and earth, and then swallow it in the body, which is why we have to concentrate on meditation to cultivate. And this Cuiwei alchemy technique attracts the purest grass and tree aura, even in the medicine garden. The aura of the grass and trees is not abundant enough to turn into aura flames. ”

"If there really is that kind of grass and trees with enough spiritual energy to be able to induce and turn into spiritual qi flames at will, then that kind of place must be an excellent place to cultivate herbs. It will attract the competition of countless sect forces, and it will become the most core and precious place of the sect. How could such an abundant aura of plants and trees be used to turn into aura flame alchemy, it would be simply overkill, if others knew, they would inevitably slap their legs and snort and angrily denounce such a loser. ”

"Cuiwei Alchemy has only been exchanged by a few people for countless years, and I have never heard of anyone who can cultivate this Cuiwei Alchemy to make a name."

"And although the threshold of this Cuiwei alchemy is very high, and the content of the spell is extremely mysterious, but because of this harsh threshold and huge defects, it is not even comparable to the mystical spells of many mystical products, and can only be classified among the cultivation spells of no grade, so its price is so low."

"Young man, I've said so much, you should know what to do." The gray-haired monk said slowly.

Zhao Feiyu nodded, and poured a wisp of his soul into the wooden platform.

The formation on the wooden platform lit up instantly, and Zhao Feiyu's figure was also obscured.

This kind of formation has a protective effect on the exercises, and if a monk wants to exchange it, the formation will be expanded, and he will be alone in it. The other monks couldn't get their hands on the jade slip of the exercise, and naturally they couldn't understand the mystery of it.

"This young man ......," the gray-haired monk sighed, shook his head a little dismay, and then turned to leave.

In the shroud of light, the jade slip released a soft light, and a soul thought also sounded in this formation.

"Are you sure you want to exchange for Cuiwei Alchemy?"

"Yes." Zhao Feiyu replied affirmatively.

"Are you sure you already know about Cuiwei Alchemy? In a hundred years, only two monks have exchanged for Cuiwei Alchemy, and no monk has been able to successfully cultivate. I'll give you another sure chance, do you want to exchange for Cuiwei Alchemy? ”

"Yes, don't think about it, I'll redeem this spell." Zhao Feiyu said affirmatively.

"Okay, just stick your identity ring on the wooden table."

Hearing this, Zhao Feiyu pasted his identity ring on the wooden platform, and a faint light poured into Zhao Feiyu's identity ring. Then it dissipates and disappears.

At the same time, the formation that bound the jade slip of Cuiwei's alchemy also dissipated.

"I didn't expect that the monks of this Yuan Treasure Pavilion were unwilling to explain even the general usage." Zhao Feiyu couldn't help but chuckle, picked up the jade slip and pasted it on his eyebrows, and a burst of gray spells instantly poured into Zhao Feiyu's mind.

"It turned out to be the young man who lit up the light of the heavenly realm on the hanging cloud ladder...... Zhang Hong's disciple ......" The soul thought who had spoken to Zhao Feiyu before muttered to himself, looking at Zhao Feiyu's figure, the soul thought looked extremely interested.
