Five years later, with the consumption of ten Breaking Spirit Pills, plus the tearing effect of the seventh-rank aura, Xu Yu went all the way from the early stage of the True Immortal to the first Golden Immortal realm. 【】

With the skyrocketing of cultivation, the biggest change for him is the control of the Heavenly Prison.

Even if the Heavenly Prison at this time is still a triple weakening and sixfold absorption.

But his foundation has really improved more than ten times, if it is said that the foundation of the True Immortal Realm Heavenly Prison can only besiege the True Immortal, it is difficult to make it escape, plus the triple weakening and the sixfold absorption, it is difficult for even the Immortal Monarch to break through this protection in an instant.

Then at this time, its foundation is that even the Golden Immortal is difficult to tear easily, plus the triple weakening and the sixfold absorption, even if a single Immortal Monarch enters, it is impossible to break it again.

For the Golden Immortals, unless there are thousands of them, it is impossible to have much impact on his Heavenly Prison, and they can only be firmly controlled by Xu Yu.

Only when the number of Immortal Monarchs reaches a certain level, such as at least ten or so people, can he tear his Heavenly Prison, or cultivate to reach the Immortal Venerable realm.

After being promoted to the Golden Immortal Realm, the first thing Xu Yu did was to refine the pill, with his level, even if he failed once when refining the Four-Rank Lingyun Pill for the first time, the materials of the Lingyun Pill were simply easy for him, and he had succeeded in the second time, and he was even fused all the way to the Four-Rank Nine-Degree Perfect Pill by him in the process of success.

Even in the past five years, Xu Yu has done another thing, that is, he is trying to use his aura to fuse star stones, his aura can improve the quality of minerals, originally according to his plan, if he can upgrade a star stone to a two-star stone, or even a three-star stone, a four-star stone or even a nine-star stone.

That's a great idea, and frankly speaking, if he can improve his success, he will become a living money printing machine, and when the time comes, he will basically have as much money as he wants!

But the imagination is beautiful, but the reality makes Xu Yu a little stunned, when he first tried to fuse a star stone, he found that his aura had lost its effect.

In other words, it wasn't a failure, but the result of the fusion was very different from what he imagined.

For example, the one-star stone after the fusion is not without change, but the change is not a two-star stone, but a diamond-shaped one-star stone that was originally the size of a palm has become a one-star stone the size of two palms.

It's like a one-grade one-degree elixir that has undergone aura fusion, and it has not become a second-grade one-degree, but a second-degree.

In the end, the aura fusion does not improve the quality of the star stone, but the size.

Although the size is also useful, at least after the fusion of aura, a one-star stone can be used as two pieces, and this wealth can be regarded as doubling, but it is a pity that it also takes time for aura-fusion, and the reserve of aura-qi takes even more time.

One fifth-class aura can only turn 1 one-star stone into 2 one-star stones, and two fifth-class aura can only turn 1 one-star stone into 3 one-star stones.

Three, four, five, and fifth-grade aura can only turn 1 two-star stone into 2 two-star stones.

A sixth-grade aura can only turn 1 three-star stone into 2 three-star stones.

............

And so on, he found that even if it took two days to create a seventh-grade aura out of nothing, he could only make 1 five-star stone become 2 five-star stones.

Three or four parts of seventh-grade aura, eight days of reserves, can make 1 six-star stone become 2 six-star stones, that is, it takes eight days to make a profit of 1 six-star stone.

It's money-making!!

Moreover, the speed of making money is already extremely fast for ordinary immortals, according to this efficiency, if he uses the seventh-grade spiritual energy fusion, he will earn 4 six-star stones in a month, and it will be five hundred and six star stones in a hundred years.

But this speed of making money is undoubtedly the more high-end the aura, the more you earn.

For example, if he has an eighth-rank aura or a ninth-rank aura fusion ** star stone, it is terrifying.

Three or four parts of eight can make 1 eight-star stone become 2 eight-star stones, and one transformation is a gap of 16,000 star stones!!

This efficiency is amazing, but the key is that it takes a lot of time for the eighth-rank aura to come out of nothing.

If he used a ready-made seventh-grade aura to fuse the eighth-rank, it would take more than thirteen hours to fuse one, but if he wanted to use this fusion in large quantities, he would undoubtedly need to fuse the first-eighth-rank from scratch.

In that case, it would take 18 days to produce nine seventh-grade spiritual qi out of nothing, and twenty days to produce an eighth-grade spiritual energy out of nothing. And three or four parts of the eighth grade can be fused to form an eight-star stone, that is, it will take eight months.

In a year, he can net one and a half eight-star stones, that is, fifteen or six-star stones, which is comparable to the "salary" of an ordinary six-rank Dan master for more than 10,000 years.

But there is no doubt that the fusion of eighth-rank spiritual energy is still not as good as the ninth-rank effect.

The fusion of ninth-grade aura with nine-star stones is the quickest, but that time is as amazing, under normal circumstances, it takes two months to have an eighth-grade aura out of nothing, and a ninth-grade aura out of nothing, it takes a year and a half.

One and a half years to make 1 nine-star stone, that's a million six-star stones.

No matter how you look at it, it is much more cost-effective to use the ninth-grade aura to fuse the nine-star stone than to use the seventh-grade aura to fuse the six-star stone.

One earns one million six-star stones a year and a half, and the other earns five hundred and six-star stones in a hundred years.

If this method of making money is known to ordinary immortals, the sensation it can bring can definitely be imagined, but unfortunately, even so, even if he uses the ninth-grade aura fusion, it will take one hundred and fifty years to fuse the wealth of 100 nine-star stones, then in the end, he just buys a soul revival grass, and he needs fifteen hundred years of reserves.

That's still the market price, without the weight of the pit people.

This method is effective, but if Xu Yu wants to resurrect Pei Guming and others like this, I am afraid that it will not be realistic at all for tens of thousands of years.

Not to mention that he doesn't have a nine-star stone now, and he doesn't have a ninth-grade aura, and the base where this Qianqiu Xing is located is only a third-rank immortal qi, and they still lack the ninth-grade immortal qi necessary to fuse the ninth-rank aura.

Therefore, the improvement of aura fusion is not without effect, but the effect is a little biased, according to that kind of fusion promotion, the pill level is only raised horizontally instead of vertically improving the quality, which is naturally a wonderful thing for him, but this star stone is only a horizontal increase in size instead of a vertical increase in quality, which really makes him a little crying and laughing.

That's far more profitable than refining a perfect-grade pill and then selling it.

And the first time he chose to refine the recovery perfect pill for sale, it was also an inevitability.

He knows very well who these four-rank pills help the most, that is the six-rank pills, among the three major halls, there is undoubtedly the most six-grade pills in the Baiyi Hall, and when there are more buyers, the price will rise, and he is naturally clear about this reason.

However, he didn't expect that this was only a little bigger, and the price of this four-grade Lingyun Pill had soared from 5 seven-star stones all the way to one hundred seven-star stones.

One hundred and seven-star stones, that is equal to one or eighteen star stones.

He also roughly estimated the price of the fourth-grade perfect-grade elixir, and felt that it should be more reasonable to sell about 1,000 six-star stones, which was at least much more cost-effective than him going to use the seventh-grade aura to make six-star stones.

But who knew that in the blink of an eye, because the supply was too small and the demand was too much, it went straight up to 16,000 star stones.

"Sure enough, it is rare and expensive, just like the treasures of the Plastic Soul Lace and the Soul Returning Grass, the materials for refining the Nine Rank Pills are ordinary to be worth a Nine Star Stone, but because the Plastic Soul Lace and so on are too rare, the normal market price requires a thousand Nine Star Stones to buy a separate material. ”

"Although I can refine the Four Rank Nine Degree Pill at will, it is best not to sell too much, if it is sold in large quantities, and there are only a few Qianqiu Xing Six Rank Pill Masters, if everyone can buy it, the price will naturally be much lower. ”

It was also when Xu Yu sighed that as someone bid for 100 Seven Star Stones, the divine thought that had been slightly delayed for a while suddenly gave birth to new waves.

"Immortal Chang Mingjian, Li is willing to give out 110 seven-star stones. ”

110 Seven Star Stones, Li Cong, who had been sluggish for a while because someone bid 100 Seven Star Stones, shot again, and this scene suddenly made the other people in an uproar again, but then the immortal who bid 100 Seven Star Stones bit straight again.

“120！”

......

Those numbers all represent the price of 1,000 six-star stones at a time, and the other immortals who are also looking at it are shocked, and now, there are only two people who are still competing for this four-grade nine-degree Lingyun Pill, only Li Cong and the immortal surnamed Huang who competes with him.

The competition between the two can be called sharp, and they don't let it go at all.

But this is inevitable, there is only one perfect elixir, but they are two people, even if the two of them plan to make a friendly concession, let the other party buy it, wait for the other party to buy it, and then transfer it to another person after the research is completed, or two people buy it together and study it together, these methods are not feasible.

A very important part of researching the perfect-grade elixir and then helping oneself to make a breakthrough in the Dan Dao is to decompose the elixir, that is, to re-decompose a perfect-grade elixir into pieces, and then completely decompose it into nothingness.

Or some Dan masters will even swallow the next perfect-grade pill by themselves at the end to carefully understand its pharmacology, no matter which of these methods is, they need to completely deplete a perfect-grade pill by themselves.

Therefore, this kind of research is basically that only one person can study it, and it is precisely because of this that many Baiyitang Six Rank Dan Masters will compete so fiercely.

But no matter what the reason is why their competition is so fierce, Xu Yu, who has been sitting on the ground and waiting for the harvest, is happy to laugh, although he knows that this situation will not be too common, but it is indeed surprising that a four-grade nine-degree pill can be sold at this price.

Even if he wants to scrape so much money in the future, he may not be able to do it, it is conceivable that once someone buys the first one at a high price, these two strong competitors will be missing one, so even if he takes out another four-grade nine-degree pill, he will never sell it at the current high price, but this does not prevent him from being surprised.

After all, in addition to the more than ten Immortal Venerable level Sixth-Rank Dan Masters at the moment, isn't there still nearly ten Immortal Rank Seventh-Rank Dan Masters in Baiyi Hall?

Relying on the four-rank nine-degree pill, he may not be able to make crazy money, but he can still refine the five-grade nine-degree, six-grade nine-degree, and those are all the help of the seventh-grade Dan master by impacting the eighth-grade.

This method can really only be used in Baiyi Hall, not anywhere else, after all, there is not a single seven-rank Dan master in Qingyun Hall now, and there are only two or three people in Qiqiao Hall, which is extremely affecting the bidding atmosphere.

It was just when Xu Yu smiled that the competition of this four-grade nine-degree pill came to an end in the end, and in the end, it was after Li Cong bid 300 seven-star stones, and the immortal surnamed Huang gave up the competition quite unwillingly.

Three hundred and seven star stones, that is three eight star stones.

This result did make Xu Yu excited, according to the calculation, even if he had been fusing with aura before, in the absence of ninth-grade aura, he could only use eighth-grade aura to fuse the eight-star stone, and it would take two years to do it.

But refining the fourth-grade pill in his hand, he only used a part of the sixth-grade spiritual energy and refined it for more than a day.
