The sudden appearance of the system prompt made Zhang Can a little confused.

But after thinking carefully for a while, Zhang Can felt that the reward given by the system was actually very reasonable.

Although Zhang Can's system is very much like a game system, the world Zhang Can lives in is not a game, but a real world.

In a real world, it doesn't matter if the amount is small, but if you wait until the later stage, Zhang Can really becomes the world's number one master who makes money as simple as breathing,

As Zhang Can uses the system to cultivate more and more disciples, the money that disappears from the Blue Star will naturally increase, and the economic system of the Blue Star will undoubtedly suffer a huge impact and destruction.

Therefore, it is obviously unreasonable to just enter and not get out of this kind of thing.

Zhang Can had thought about this question before, but because he was still far from becoming the world's No. 1 master, he didn't think about it deeply.

But this time, with the appearance of the system's rewards, Zhang Can finally understood that the system's recharge option was really not nonsense.

Qi Yuan Stone is the product of value given by the system, which can be exchanged for those currencies that have disappeared.

As for what exactly is the so-called Qi Yuan Stone?

It's not that Zhang Can didn't investigate carefully, but to this day, all experts and scholars have not given a clear answer.

The only thing that can be determined is that the Qi Yuan Stone has the effect of assisting the cultivation and recovery of martial artists above the level of internal strength.

For those genius martial artists whose realm has risen suddenly because of their epiphany, cultivating with Qi Yuan Stones can allow their internal strength to catch up with their martial arts realm as soon as possible.

And for those martial artists whose internal strength has been damaged due to battle or injury, the Qi Yuan Stone can allow them to recover a large amount of internal force in a very short time.

To put it simply, Qiyuan Stone is equivalent to a natural internal force medicine.

However, when it comes to the utilization of Qi Yuan Stone, the warriors are far inferior to their old enemies, the alien beasts.

According to the research of alien beast scholars, since ancient times, except for the legendary four divine beasts, the growth and transformation of all other alien beasts are inseparable from the help of Qi Yuan Stone.

The Qi Yuan Stone is not only the food of the alien beasts, but also the key to their ability to evolve and transform.

In the ancient period, almost all the Qi Yuan Stone veins on the Blue Star were all controlled by powerful beasts.

If the warriors want to get a little bit of Qi Yuan Stone, in addition to going to the territory of the alien beast to pull out the teeth, they can only pray for the blessing of the martial god, and luck has come.

In short, in the ancient period, even if it was only the lowest-level human-rank Qi Yuan Stone, it was definitely a luxury among luxury goods for martial artists.

For the sake of a human-level Qi Yuan Stone, it is not uncommon for several great grandmasters to break their heads and bleed.

But today, with the reversal of the status of humans and alien beasts, the Qi Yuan Stone and the Qi Yuan Stone veins are no longer as rare and precious as in ancient times.

After Tianren Group opened the contract mining rights of gas yuan stone veins, the price of gas yuan stone plummeted all the way.

So much so that even ordinary people can buy it as long as they grit their teeth.

Of course, ordinary people actually have no effect on buying Qi Yuan Stone.

But I can't help but keep spreading the news that "Qi Yuan Stone can not only help martial artists cultivate, but also prolong the life of ordinary people";

In addition, after several experiments, scientists still can't confirm that Qi Yuan Stone cannot enhance the physique of ordinary people, so now more and more ordinary people are going to buy jewelry made of Qi Yuan Stone.

Others don't mention it for the time being, in fact, just on Hao Youqian's body, Zhang Can found three items inlaid with Qi Yuan Stone last time.

Belts, watches, lighters.

As for other things, whether Hao Youqian has other Qi Yuan stone ornaments on his body, Zhang Can is not very clear.

However, as far as Zhang Can knows, there are already some well-known underwear brands that have launched a lot of boutique underwear with a "blessing" effect.

With Hao's wealth, maybe he will buy it and try it?

Ahem, of course, mentioning Hao Youqian is not to say that Hao Youqian is superstitious,

But it can be seen from the fact that Hao Youqian has Qi Yuan Stone jewelry on his body, at least the upper class people on the Blue Star are still very willing to pay for Qi Yuan Stone.

As for whether they really believed in the special effects of the Qi Yuan Stone, or simply to prove their status, it was unknown.

In short, the sales of gas yuan stone are not a problem.

So, keep charging money to exchange for Qi Yuan Stone, then sell it, and then recharge it again, so as to increase the recharge amount of the nesting doll, is it okay?

Theoretically, it is possible, but unfortunately, it is very difficult to do.

Because, on the Blue Star, the sale of Qi Yuan Stone is strictly monitored by various countries, and there is a strict registration system for both sales and purchases.

Of course, in some black markets, it is still possible to buy Qi Yuan Stones from unknown sources.

But the problem is that the market price of the low-grade Qi Yuan Stone is 10,000 Daxia Coins, while the selling price on the black market is 12,000 Daxia Coins, and the purchase price is 5,000 Daxia Coins.

Therefore, selling a large number of gas yuan stones on the black market is simply taking money to burn and play!

Moreover, don't think that the so-called black market can really do whatever you want, and you can sell whatever you want.

After all, the black market is an underground exchange that is not officially regulated, but it is not a place out of this world without official eyeline.

It is nothing for a fresh face to sell one or two Qi Yuan Stones in these black markets, but if someone dares to sell dozens or hundreds of them, the black market can instantly become a black prison and a black tomb.

Not to mention whether he survives after being targeted, the ensuing joint pursuit of the official and dark parties is definitely not something that ordinary people can afford.

Before becoming the invincible strongest hall owner in the world, Zhang Can did not have the ability to fight the world alone.

Moreover, the upgrade requirement for the system's reward veins is to recharge another billion Daxia coins.

In other words, it is 100,000 low-grade Qi Yuan Stones.

With so many Qi Yuan Stones, even if Zhang Can was really allowed to sell them casually, it would be impossible for him to sell them out in a short period of time!

Zhang Can felt that if someone really wondered how to resell the recharge quota of the Qi Yuan Stone fraud system because of this, then his story would definitely be written into a book, called - My Life of Moving Bricks after Crossing.

Anyway, Zhang Can has no idea about this at all.

As for what to do with the Qi Yuan Stone rewarded by the system, Zhang Can was even less worried.

Not to mention that Zhang Can's martial arts hall has a large consumer of Qi Yuan Stone-Phantom Qilin Qiqi, which belongs to the kind that can eat as much as you want.

Just in the future, Zhang Can's disciples who have been promoted through krypton gold are absolutely inseparable from the assistance of Qi Yuan Stone when cultivating.

At that time, maybe Zhang Can will have to take the initiative to buy Qi Yuan Stone in order to meet the consumption in the martial arts hall.

In short, this reward of the system is definitely not a bug, and Zhang Can is also very satisfied with this reward.
