Looking at the spirit stone in his hand, Gu Xuan's whole person was stunned.

The best spirit stone?

According to the degree of aura, the spirit stone is from low to high, and the atmosphere is low, medium, high, and excellent.

The exchange ratio between each other basically follows the exchange rate of one to one.

A medium-grade spirit stone is equivalent to a hundred lower-grade spirit stones, a high-grade spirit stone is equivalent to a hundred medium-grade spirit stones, and a top-grade spirit stone is equivalent to a hundred high-grade spirit stones.

Generally speaking, things like spirit stones are crystals that contain huge spiritual energy.

Ordinary spirit stones are mostly in places where spiritual energy is abundant, where spiritual veins gather, and spiritual veins are produced after thousands of years.

And since it is born of heaven and earth, the content of aura in it is naturally not immutable.

In most worlds, although spirit stones are also divided into lower grade, middle grade, upper grade and best grade, spirit stones cannot be exchanged at a fixed ratio.

It is also a low-grade spirit stone, if the low-grade spirit stone containing the least aura is used as a unit of 1, then the lower-grade spirit stone with the strongest aura can even reach forty or fifty, or even ninety-nine, and when the energy contained in it breaks through the limit of 100, it can be called a medium-grade spirit stone.

Therefore, in most worlds, spirit stones cannot be used as a unified currency, although spirit stones have many uses and cannot be obtained during cultivation.

In most worlds, there is a unified currency in addition to the spirit stone, and after the currency is traded, it can be exchanged for the same amount of energy spirit stone if you wish.

However, this situation was applicable to most worlds, but the Pancheng Realm where Gu Xuan was located, or the entire Great Chaos World, was different from the vast majority of other worlds.

Pancheng, and even in the entire Great Chaos World, there are many Xiongcheng like Pancheng, and the energy used for cultivation is chaotic aura.

This kind of aura was born from the chaotic boundless chaos, and it could not be absorbed by low-level cultivators for cultivation.

Under the intervention of a mysterious law, the power of chaos will be purified when it approaches the city, turning it into a chaotic aura that can be absorbed by ordinary people.

And the spirit stones in Pancheng are also generated by heaven and earth after condensing a certain concentration of chaotic spiritual power in this situation.

Therefore, the spirit stones in Pancheng, the chaotic power contained in each level of spirit stones is really fixed.

If you take an unused low-grade spirit stone as a unit, then all the chaos aura in the lower-grade spirit stone is one unit, and all the medium-grade spirit stones contain one hundred units, and so on.

So, 1 top-grade spirit stone = 100 upper-grade spirit stone = 10,000 middle-grade spirit stone = 100,000 lower-grade spirit stone?

Gu Xuan looked down at a top-grade spirit stone in his hand.

Just such a small piece in his hand is equivalent to 100,000 spirit stones?

One value = 10 negative emotions = 100 financial value.

A top-grade spirit stone = 100,000 lower-grade spirit stones = 100,000 wealth value = 1,000 silk value.

One unit of World Origin = 10,000,000 of the value of the world, so as long as you can get 10,000 spirit stones like this and successfully spend them, you can get one unit of World Origin?

Thinking of this, Gu Xuan couldn't help but feel a little excited.

After all, he could hear it clearly before, like that pretending to be forced to slap the face system, all the property added up to more than a thousand world origins.

In this way, if you spend 20 million top-grade spirit stones, wouldn't you be able to become even more powerful than that system?

Gu Xuan looked at the top-grade spirit stone in his hand and felt that he was finally a real god with 100,000 low-grade spirit stones in his hand.

And feeling the truest thoughts in Gu Xuan's heart, Su Luo was indeed speechless for a while.

After enduring it for a long time, Su Luo couldn't help but speak.

"Host, is your math taught by your PE teacher?"

Gu Xuan: "!! ”

Su Luo: "??? ”

Gu Xuan: "System, how do you know?" ”

Su Luo: "......"

Is it really taught by a physical education teacher?

"Give the host a suggestion, don't do arithmetic in the future, the system is afraid that one day your physical education teacher's coffin board will not be able to hold it down."

Gu Xuan: "!!? ”

"Huh."

Su Luo chuckled, "Host, do the math, and then tell me seriously."

One unit of world origin is equivalent to 10 million yuan of debrinction, 100 million negative emotions, and 10 billion of financial value.

What is the exchange ratio between Sentiment, Negative Sentiment and Wealth? ”

Gu Xuan blinked, "1:10:100." ”

Su Luo: "......"

"Host, you calculate again, the exchange ratio between spirit stones is 1:100, how many low-grade spirit stones can be exchanged for that top-grade spirit stone?"

Gu Xuan frowned, "Isn't it one hundred thousand?" ”

Su Luo: "......"

"Host, don't be busy going to the loser today, let's go and see your physical education teacher's grave first, I suspect that your physical education teacher's grave has been blown up."

Gu Xuan: "....."

"No, is there something wrong with the system?

Spending 10,000 of these top-grade spirit stones can obtain one unit of World Origin, isn't it? ”

Su Luo: "......"

You..... What you said makes so much sense that I'm speechless.

"There is a basic course of elementary school mathematics in the exchange mall, and the price is only a penny, so it is recommended that the host exchange it."

Gu Xuan's mind moved and found this basic course for elementary school mathematics, and after looking at it, he really only needed a little bit of money.

A white talisman worth a hundred yuan has been exchanged, not to mention such a basic course for elementary school that is personally recommended by the system?

Gu Xuan didn't hesitate to exchange it directly.

After the exchange, a book in the shape of a primary school textbook appeared in Gu Xuan's mind, and with a light touch of Gu Xuan's mind, the book shattered, turning into the most basic knowledge and integrating into Gu Xuan's mind.

After a few breaths, Gu Xuan opened his eyes, and there was ..... in his eyes A bit of unnatural embarrassment flashed.

"Ahem, system, after some deep thinking by this host, I have finally solved your problem.

The exchange ratio between the value of the decorate, the negative emotion and the value of wealth should be 1:10:1000, and one top-grade spirit stone is equivalent to one million low-grade spirit stones.

What do you think? Is this host right? ”

Su Luo: "....."

You look so shameless, you really have a bit of my demeanor back then.

Regarding the silent ridicule of his own system, Gu Xuan didn't blush or anything.

While recognizing his previous algorithm mistakes, Gu Xuan was also secretly frightened in his heart.

It turns out that his previous computing power was already that bad?

Although the ratio between the number of spirit stones consumed and the origin of the world is clear, the problem is that the exchange between the value of the spirit stone and the value of wealth is directly wrong.

What's even more outrageous is that he miscalculated how many low-grade spirit stones a piece of top-grade spirit stone can be exchanged.

This is thanks to the fact that he now recognizes his mistake, otherwise he really has to take the best spirit stone as a hundred thousand lower grade spirit stones to spend, and after understanding the truth in the future, he must not cry to death?

This matter please, taught Gu Xuan two truths:

First, two wrong pieces of information may be able to get the right answer, but the final answer is correct, which does not mean that the error in the process does not have to pay a price.

Like what..... He almost faced the terrifying consequences of spending a top-grade spirit stone as a hundred thousand low-grade spirit stones.

Second, the math taught by the physical education teacher is really not as effective as the math teacher.

It seems that for the rise and fall of the family and the continuation of the family, it is necessary for him to suggest to his father that he can't find a physical education teacher to teach mathematics in the future.

Although it is said that the family respects martial arts, force is the foundation of the family's prosperity.

But a good martial artist, he is not necessarily a good math teacher.

I think that if I had a good math teacher, I would have made such a mistake just now.

Let your own system see the joke in vain.

However, speaking of the system.....

With the previous experience of no taboo charms and a white talisman seal, and after the incident of mastering the mathematical ability of primary school students in an instant after the basic course of elementary school mathematics.

Gu Xuan suddenly realized a truth - all products produced by the system must be high-quality.

So..... His first priority in the future is to pretend to be forced to slap his face and die, scatter wealth and ruin the family.

With such an awesome system, as long as there is enough energy to exchange, let alone a small ancient town, Gu Xuan feels that he can lead the Pan clan to stand at the peak of the entire continent.

When thinking like this, Gu Xuan suddenly remembered that after completing the first side quest in his life before, he was called by his father for questioning because he accidentally demolished the ancestral hall, and he had forgotten what the prize was for checking the lottery of side quest rewards.

Although the bastard system is full of insiders, the lottery is a lottery of designated prizes operated in the dark.

But the prize has already been received, and what features I haven't checked yet.

Thinking so, Gu Xuan took out a purple talisman seal from the package with a single thought.

Seeing the talisman turn purple, Gu Xuan's eyes were filled with a bit of anticipation.

A white talisman is white, and the effect is already not small.

The golden talisman seal solved the dilemma of his qualifications being sealed, and at the same time helped him find the field, and by the way, he also demolished the ancestral ancestral hall.

So..... How powerful is this purple sigil?

Well..... No matter how powerful it is.

Gu Xuan looked at the ancestral hall that had disappeared from the ancestral land of the Pan clan, leaving only an empty space, and felt a lot more relieved in his heart.

Not to mention the power, at least ..... There's no need to worry that this guy will tear down the ancestral hall again.

After all, the ancestral hall has been demolished, hasn't it?

But..... Not only the ancestral hall, but when you use this purple talisman seal again, you must be careful and careful, and you must not dismantle anything from the Pan clan.

After all..... As the young master of the Pan clan, every flower and tree of the Pan clan is his future wealth.

While thinking like this, Gu Xuan's gaze fell on the purple talisman seal in his hand.

And then.....

Item: A purple sigil.

Attributes: A purple thunder is sealed in the purple rune seal, and the thunder is everywhere, and everything does not exist under the mixed element.

PS: It is more powerful, please use it with caution.

Seeing this, Gu Xuan secretly said in his heart that it was dangerous.

Fortunately, I was cautious and didn't use the talisman indiscriminately, but fortunately, I remembered it and took it out and took a look.

Otherwise..... Even the system reminds you to use things carefully, once you take it out and use it without looking at it, what kind of terrible consequences will it cause..... Even he couldn't have predicted it.

While secretly saying that he was lucky, Gu Xuan's gaze almost subconsciously fell to the last line.

With the precedent of golden rune paper and a white rune seal, Gu Xuan would not think that all runes were used in the same way.

Since this thing is very powerful, it is naturally a hole card to save your life.

The hole cards that save your life naturally have to be remembered clearly.

And then.....

Seeing this, Gu Xuan's whole person froze there.

How to use: In view of the fact that the Zixiao Divine Thunder is the host's life-saving hole card, there is no need to urge, and the talisman seal is taken out of the package for three seconds and then activates itself.

Gu Xuan: "......"
