When Jiang Mu returned to Fuyun Mountain, it was already the beginning of the lanterns, and the lights of thousands of homes were on.

Unexpectedly, the old man of Shangyue of Taiyi Gate was waiting for him outside Yunhufang City.

At this time, the old guy's gaze at Jiang Mu was already quite jealous, but thinking about it, the person who could call Fan Khotan by his name was not something he could afford to provoke.

"Master Jiang, this is the method of preparing spirit stones that the old man said, please take a look."

Old man Shang Yue changed his title and became a little respectful.

Jiang Mu didn't care about this detail, he was still very curious about the method of preparing this spirit stone, but when he quickly swept the contents inside, his brows furrowed slightly.

It turns out that the so-called method of preparing spirit stones is a formation with the anti-Dao method divine pattern as the core, by continuously absorbing the aura of heaven and earth, and then letting the aura artificially increase the concentration, and then putting the stones with less impurities into it, after soaking for a period of time, the fresh spirit stones will come out.

"Friends of Shang Dao, don't you Taiyi Sect also undertake the deployment of this formation?"

Jiang Mu asked thoughtfully.

"Exactly, of course, if Master Jiang is interested, my Taiyi Gate can give a twenty-percent discount."

"What is the color of the spirit stone?"

"Ten percent, the quantity and quality of the spiritual energy in this prepared spirit stone are the same as those of the original ore spirit stone."

"If it's so good, it must have a drawback."

"Hah! Master Jiang's eyes are like torches, that's right, the biggest difference between the preparation of spirit stones and the original ore spirit stones is in the storage time. The low-grade raw ore spirit stone can usually be stored for a hundred years, the medium-grade raw ore spirit stone can be stored for hundreds of years, the high-grade raw ore spirit stone can be stored for thousands of years, and the best raw ore spirit stone can be stored for tens of thousands of years. ”

"And the preparation of spirit stones, even if they are the most conscientious, can only be stored for about twenty years, and the rest are either seventeen or eighteen years, or fifteen or sixteen years, or even ten years of profiteers, and I Taiyimen disdain to cooperate with them."

Shang Yue didn't know that it was because of Fan Tian, the head of the Divine Sword Sect, and it was not taboo to talk about these secrets.

But Jiang Mu's heart sank to the abyss, because if this was the case, then the nearly 500,000 spirit stones in his hand, as well as the 200,000 spirit stones in Fuyun Zongfang City, were all prepared spirit stones?

And he lived two lives, and he never knew about it.

But then after thinking about it, he understood that the spirit stones circulating on the market are used for currency, and few people reserve them, and even if they do, they are all used up within a few years, and it is difficult to find the secret, after all, in addition to the different storage time, the effect of preparing spirit stones and raw ore spirit stones is almost the same.

It's just that in this way, those sects that have mastered the spirit stone veins will never be short of immortal cultivation materials, and they will not have to work hard at all, and they can harvest the wealth created by the entire immortal cultivation world.

If you think about the five super sects, and then think about the slave-like days of scattered cultivators at the bottom, you can almost know it.

Taking a deep breath, Jiang Mu calmed down and asked:

"In this way, there should be more and more spirit stones on the market, why do I feel that the spirit stones on the market are decreasing day by day?"

"Hah, that's it!" Shang Yue looked around, hesitated for a moment, and said: "Actually, it's simple, among the major sects, of course, there are masters, and they also know the disadvantages of preparing spirit stones, so every hundred years, the number of spirit stones flowing into the Fang City will be reduced, and this process will last for about ten years." ”

"This is already an agreed custom, in addition, there is another reason that the ten places in Kyushu in the immortal cultivation world are actually the territories of the major immortal cultivation sects, such as the six counties in the south of the Yangtze River, the five counties in Shannan, the five counties in the north of Shanbei, and most of the Broken Dragon Mountain, all of which are controlled by the Divine Sword Sect, which is also a convention."

"I'm not afraid of Master Jiang's jokes, if it weren't for the fact that you have a great relationship with the Divine Sword Sect, it would be impossible for the old man to tell you about it. In the entire Nanzhou, the only ones who can do this preparation of spirit stones are the Shenjian Gate, the Prayer Heaven Sect, the Ten Thousand Souls Sect, and my Taiyi Gate, but the Prayer Heaven Sect, the Ten Thousand Souls Sect and my Taiyi Sect are only allowed to flow into Nanzhou City every year five million pieces of preparation spirit stones. ”

"If there are other sects that want to make waves in the Nanzhou realm, it is against the Divine Sword Sect."

After listening to the old man Shang Yue's explanation, Jiang Mu couldn't help but break out in a cold sweat, sure enough, the level of his previous life was too low and too low, and the toss of his life, seeing it, was about to hit the threshold of the Divine Sword Gate.

He's still too self-righteous.

This immortal cultivation realm is much deeper than he imagined.

However, this can also make sense, why the spiritual energy tide erupts, and the major sects will be forced to hide, there are really very few raw ore spirit stones in their hands.

And no matter how many spirit stones are prepared, they can only support about twenty years.

He had to adjust his plans in time.

"Brother Shangdao, thank you, if I am interested in this in the future, I will definitely seek your sect's help."

In the flash of his mind, Jiang Mu smiled and thanked him.

"Haha, it's easy to say, in the future, in this Qinge County, I want Master Jiang to take care of one or two."

Shang Yue laughed heartily, no matter what the relationship between Jiang Mu and Fan Tian was, the purpose of his friendship was also achieved.

In the world of cultivating immortals, only by being harmonious can you make money.

When Shang Yue left, Jiang Mu did not return to the mountain gate, collected the flying magic weapon, and landed on the thousand-mile Great Wall built along the bank of the Qin River, he wanted to be quiet now.

Walking on the Great Wall, with the surging river on one side and the lights of thousands of homes on the other, the powerful divine thoughts slowly spread, as if hearing the heartbeat of this heaven and earth.

Decay and heaviness, as if an era is finally over, irretrievable.

Now Jiang Mu is very sure of this.

Preparation of spirit stones, what a good idea, you don't have to do it yourself, there will be a bottom level of loose cultivation, the bottom sect will send a steady stream of resources to the door, middle and upper level immortal cultivators, the immortal sect can make every effort to improve the realm, and finally break through the Mahayana, soar in the day, how good.

This is equivalent to prostituting the aura of heaven and earth in vain, letting countless low-level people make cattle and horses for themselves, and finally soar to the fairy world without much effort, which is really moist.

Jiang Mu smiled bitterly, at this time, he suddenly thought of that Gu Immortal Promise, because he now felt more and more that this Gu Immortal Promise was not so much like a promise, not too much like a warning, more like, a prophecy!

The thought flashed through my mind like a thunderbolt, and there was no way to stop it.

Then he thought of what Fan Tian said before, it was rumored that the Gu Immortals had Sannuo Immortal Yin left, and it was in the Demon Hell Mountain.

If this first promise is a prophecy, then it also means that the second promise and the third promise are also prophecy, what will be prophesied?

Jiang Mu suddenly had the urge to go to Demon Hell Mountain.

He believed that there were many people who had the same thoughts as him, Li Xin, the elder of the Divine Sword Sect 1,200 years ago, was like this, why did they risk their lives to go to this Demon Hell Mountain?

Curious?

Or worship, or unwilling?

Today he could think that the promise of the Gu Immortals might be a prophecy, which meant that others could think of it as well.

For a while, Jiang Mu's heart was extremely vigilant, and he suddenly felt that if this was really the case, wouldn't they, the immortal cultivation realm, the entire heaven and earth, and hundreds of trillions of living beings, be arranged by someone clearly?

After a long time, Jiang Mu withdrew his thoughts, and his heart also returned to peace, but there was one thought that was condensing.

"In any case, before the aura tide erupts, I have to go to the Demon Hell Mountain, which may be the closest moment I have to the truth."

Jiang Mu is very sober, now, the aura of heaven and earth is quite normal, he can also recover and replenish the sword yuan power, and when the tide of aura comes, the aura of heaven and earth will be cut off instantly, then it will be too late.

Without the aura transformation sword yuan power, he is nothing!

Of course, he is not stupid, he will not break in directly, at least he has to let him overturn a few more demon suppression towers, rebuild three or two more times, and reserve tens of millions of wisps of sword yuan power, so that he can have the courage to break into the Demon Hell Mountain.

He didn't want to be the second Li Xin.
