"Grandma, where can I get these three main materials..."

Looking at the three main materials in the jade slips, Su Xiaofan had a headache. They were all rare treasures in the universe, and more importantly, the demand was extremely high.

His spiritual thoughts entered the storage ring, and a spiritual stone emitting space fluctuations appeared in Su Xiaofan's hand.

Different from the ethereal stone that Su Xiaofan had obtained before, this low-grade ethereal stone was in the shape of a ball, about the size of a baby's fist.

There were nine holes on the ethereal stone. Su Xiaofan explored it with his spiritual mind and suddenly felt that there seemed to be another space in the nine holes.

"I don't know what the best ethereal stone looks like."

Su Xiaofan observed for a while and firmly memorized the energy fluctuations of the ethereal stone. At the same time, he also had a way to find the ethereal stone.

According to what Venerable Huo Tian said, only in the most violent areas of the turbulent space can the ethereal stone be born.

But in that kind of area, even if Venerable Jinxian enters, there will be great danger.

Usually the way to get the Void Spirit Stone is to stay outside the violent space.

If you are lucky, you can get one or two ethereal stones swept up by turbulent currents every hundred years, but the quality of the ethereal stones depends entirely on luck.

"It only takes a hundred years to get one or two yuan. How can I have the time to guard it?"

Su Xiaofan shook his head speechlessly. These materials for refining the secret door are not available at all, but there is still a chance.

Whether it is a purple crystal elemental stone or an ethereal stone, Venerable Golden Immortal Qi has a chance to get it together, just like Venerable Huo Tian. If you can't get a good one, you can still make a set of ordinary ones.

But that would take a long time. Su Xiaofan, who was less than two hundred years old, had no concept of that at all, and Su Xiaofan didn't think he could afford it.

"How about refining it using existing materials?"

Su Xiaofan scratched his head. There was a decent set of materials in the storage ring, but the secret door that was refined was definitely the worst.

Not to mention the possibility that this kind of secret door may collapse during teleportation, it can only teleport a distance of one or two galaxies at a time, which is unacceptable to Su Xiaofan.

You must know that the distance between the Golden Yang Realm and the original galaxy, that is, the original star realm, is separated by an unknown number of billions of galaxy realms.

If this kind of secret door was used to teleport, just opening the secret door plus the recovery time might take Su Xiaofan hundreds of thousands or even millions of years.

"Hey, why did I forget about Wanwu Mall?"

Su Xiaofan suddenly slapped his head. Just because he couldn't find the materials didn't mean he couldn't get them. Su Xiaofan cursed secretly and put his spiritual thoughts into the system.

"Elemental Stone!"

In the material classification of Wanwu Mall, Su Xiaofan found the first main material.

Seeing the picture that was shown first, Su Xiaofan's eyes couldn't help but light up. A low-grade Yuan Stone was only worth five hundred to repair.

Refining the secret door requires at least three thousand yuan stones. If all low-grade stones are used, the repair value will be 1.5 million points, which Su Xiaofan can still afford.

Of course, the minimum requirement for refining the Secret Sect is to need middle-grade Yuan Stone, and low-grade ones are obviously not acceptable.

"Mid-grade, how much does a mid-grade Yuan Stone cost?"

When Su Xiaofan saw the price of the middle-grade Yuan Stone, his heart sank. The middle-grade Yuan Stone actually had a repair value of 5,000 points per piece.

"Venerable Huo Tian is giving himself fifteen million repair points?"

If you exchange three thousand pieces of mid-grade Yuan Stone from the Mall of All Things, you will need to pay fifteen million points of repair value. Calculating it this way, Venerable Huo Tian really did not treat Su Xiaofan badly.

"What the hell, isn't this a scam?"

When Su Xiaofan saw the price of a high-grade Yuan Stone, he couldn't help but curse, because a high-grade Yuan Stone actually required 50,000 points of repair value.

In other words, if the main material for refining the Secret Sect were to use high-grade Yuan Stone, Su Xiaofan would have to pay 150 million repair points to purchase it.

With his heart trembling with excitement, Su Xiaofan clicked on the price of the top quality Yuan Stone. He almost spit out a mouthful of blood when he looked at it.

Just as Su Xiaofan thought, the price of a top-grade Yuan Stone is 500,000 points of repair value!

Su Xiaofan, who was originally working on refining the secret door with all the best materials, was directly awakened by a sap. He couldn't get out 1.5 billion repair points even if he killed Su Xiaofan.

In fact, not only Su Xiaofan, there really is no one in the universe whose secret door is all refined with top-grade Yuan Stone.

Even those powerful cultivators can only mix some top-grade Yuan stones in the secret door at most, and all use top-grade Yuan stones. Even the most powerful cultivators do not deserve this dream.

"It's silly. Why don't you just look for the secret door and be done with it?"

Su Xiaofan changed his mind and directly searched for the secret door. Not to mention, there was an option for this item in the Wanwu Mall.

But seeing the price of the secret door, Su Xiaofan was dumbfounded again.

The secret door in the Mall of All Things is a semi-finished product, because it requires the cultivator to refine it into the body, which is a bit like a natal magic weapon.

But even for the semi-finished secret door, the price made Su Xiaofan completely despair.

There are four secret door options.

The lowest level secret door has a repair value of 800 million points on the Everything Mall.

The slightly better one has a repair value of 3 billion points, and the function improvement is almost five times that of the lowest level.

Then the secret door with eight billion repair points was a hundred times more powerful than the lowest level secret door. Su Xiaofan was a little jealous when he looked at it.

As for the last secret door, it requires 15 billion points of repair value. The function improvement is not introduced, but there is a bracket after the price that says out of stock.

"What the hell is this? It's still out of stock."

Su Xiaofan was already numb to the price of the secret door. In fact, the difference between the repair value of 800 million points and 15 billion points was not big to Su Xiaofan, because he couldn't take it out.

"It shouldn't be so expensive."

Su Xiaofan felt that the price offered by the mall was a bit shady, because 3,000 mid-grade Yuan stones could be purchased with only 15 million repair points.

Even if the other two materials cost 15 million points, the total repair value would be less than 50 million points, but the system gave a sky-high price of 800 million points.

"Let's take a look first."

Su Xiaofan exited the secret door option and found Amethyst.

Sure enough, the price of amethyst also fluctuates greatly depending on its quality.

The price of amethyst is much more expensive than that of primeval stones. One amethyst that meets the secret of refining requires 50,000 amethyst points.

According to the requirements of the secret refining door, one thousand amethysts equals 50 million points of repair value.

As for the top-grade amethyst, Su Xiaofan glanced at it and couldn't help but twitching at the corner of his mouth. A top-grade amethyst requires one million repair points.

Now Su Xiaofan finally understood where the price of the last secret door came from, because the amethyst material alone would cost one billion repair points.

When I finally saw the ethereal stone, the price made Su Xiaofan feel uneasy. I couldn't afford it anyway, I was just looking at it.

The best ethereal stone has a repair value of 10 million points. The minimum refining requirement is 100 yuan, and it requires at least a billion repair points.

With Su Xiaofan's current net worth, he can buy it for 2.8 yuan, which is not even a fraction.

"Venerable Huo Tian is really generous. He gave me nearly 200 million points worth of repair materials."

After Su Xiaofan's mind withdrew from the Mall of All Things, he immediately felt that the wine at hand no longer tasted good. He felt that someone as poor as himself was no longer worthy of drinking.

As for the reason why the lowest level secret door requires 800 million repair points, Su Xiaofan also found it.

Refining the secret door requires not only those three main materials, but also more than 900 kinds of materials.

Although some of these materials are very common, they are also valuable, and together they are worth one or two billion in repair value.

Su Xiaofan really didn't expect that Venerable Huo Tian would be so generous. This set of materials for refining the secret door alone was enough for Su Xiaofan to help him.

"These are the most precious materials, can they be absorbed?"

An idea suddenly came to Su Xiaofan's mind. When he observed these materials before, he did not ask whether the system could absorb them.

[High-quality ethereal stone can be absorbed. Is it absorbed? 】

Su Xiaofan stared at the ethereal stone in his hand, and the system indeed gave the word "absorbable".

"Would you like to absorb a piece and try to see if you can find some loopholes?"

Su Xiaofan was a little hesitant. Purchasing a high-grade ethereal stone from the mall requires 500,000 points of repair value. If it does not give you 500,000 points after absorption, Su Xiaofan will lose money.

"absorb!"

Su Xiaofan gritted his teeth. There were a hundred ethereal stones in the storage ring. If one was missing, it would be able to make up for it later.

[Repair value: 28100000!]

"What the hell, it's the same trap as Qi Ling!"

Seeing the repair value points in his mind, Su Xiaofan almost cursed.

Purchasing a high-grade ethereal stone from the mall cost one million points each, but Su Xiaofan only converted it into a repair value of 100,000 points after absorbing it. This was simply too deceiving.

"Item Spirit, get out!"

Su Xiaofan's spiritual thoughts fluctuated, and the powerful spiritual thoughts caused the entire repair system to tremble.

"Have you changed the price of the product?"

At this time, in Su Xiaofan's sea of ​​consciousness, his spiritual thoughts were like the power of thunder, shocking the system's weapon spirit.

"No!" Qi Ling replied dryly, as if he was frightened by Su Xiaofan.

The weapon spirit also felt that although he was in the system, the system was parasitic in Su Xiaofan's sea of ​​consciousness.
