In this martial arts world where the aura of heaven and earth is strong, the spirit stone mine is a renewable resource, but the rate of regeneration is extremely slow.

From the beginning of this realm to the present, under the uncontrolled mining, the number of spirit stone mines is much less than at the beginning, and it is not until after the human race settles that a planned mining method is invented, so that the number of spirit stone mines is no longer reduced.

In essence, the formation of the spirit stone mine is actually the ley line aura in the process of running underground, through some natural formations, the free heaven and earth aura will be gathered here and injected into special ores, so as to form various attributes and grades of spirit stones, the original source of the popular spirit gathering array is from this spirit stone mine and the cave heaven blessed land.

If the amount of mining exceeds one-third of the total amount at one time, the speed of spirit stone regeneration will be greatly affected.

Therefore, on the premise of not mining more than one-third of a certain spirit stone mine at a time, it can be mined according to the speed of its own recovery, so that unless the leylines are circulating, it can be said that it will never be exhausted.

And this only medium-grade spirit stone mine in Dongping County is the medium-grade spirit stone that can mine about 800 pieces of medium-grade spirit stones every year, although 800 medium-grade spirit stones do not seem to be much, but this spirit stone mine is a great wealth in the eyes of any force, after all, a force can occupy it for ten years, twenty years, or even hundreds of years and thousands of years, so how amazing is the income obtained in this way? Therefore, this medium-grade spirit stone mine is the most valuable industry in the entire county.

The number of spirit stone mines occupied by a top-level force like the Seven Killing Hall in the entire Central Domain was hundreds or thousands, and this income alone could stabilize at around tens of thousands of top-grade spirit stones in a year.

It is precisely because this spirit stone mine is a stable source of income with extremely high value that those first-class sects in the alliance will attack everywhere, not only the three sects of the righteous path, but also the neutral Seven Killing Palace.

Moreover, where there is a spiritual stone mine, it also means that the earth's leylines are rich in spiritual energy, which also provides convenience for them to cultivate the Red Dragon Sutra.

Ever since he was reminded by Gu Qianqian, Li Shenzhou looked through the introduction of the Lingshi Mine in Dongping County. Although there were only eight hundred medium-grade spirit stones that year, it was not enough for Lu Xiaoman and Xiaoxiao to cultivate for a few days, and he didn't take it seriously at all, but Lu Xiaoman took over the task of guarding the spirit stone mine from the sect after all.

Although he lost it in the face of a first-class sect with a powerhouse in the Extraordinary Realm, since Song Ming of the Dongping Sword Sect had a holiday with them, how could Li Shenzhou make him feel better, he Li Shenzhou has never been a character who repays grievances with virtue.

"Li Gongzi, did you have a harvest at that auction yesterday? I still have a lot of good specialties in Dongping County, right?"

When Li Shenzhou walked out of the room after reading the information, he happened to meet Jiang Yuhe who came over.

Although Li Shenzhou felt that he was talking too deliberately, pretending to be close, he did not suspect that there was anything wrong with this, and said casually: "Yes, it is indeed different from the inland." ”

And Jiang Yuhe seemed to be just looking for an excuse to greet and talk, and he didn't dig deeper.

"By the way, I also asked Gongzi Li to bring a message to Senior Sister Lu, the garrison task arranged by this sect had better be over, otherwise if it is known by the above, I am afraid it will not be easy to explain," Jiang Yuhe smiled helplessly, and spread his hands as he spoke.

Li Shenzhou's heart moved when he heard this, and there was a problem with Jiang Yuhe's words that he summarized, but it was inconvenient to think about it at this time.

"Okay Hall Master Jiang, I'll bring the words here!" Li Shenzhou nodded in response, and then said goodbye to him and left.

Yesterday, I just learned from Gu Qianqian that the Dongping Sword Sect was going to make a move against the spirit stone mine, and today this Jiang Yuhe wanted Lu Xiaoman to go and garrison it, is this really a coincidence? But Lu Xiaoman and him Jiang Yuhe have no grudge, if it is a conspiracy, then what is it for?

Along the way, Li Shenzhou secretly pondered, but as for whether the news Gu Qianqian said was true or false, he didn't doubt it at all.

Although he didn't know what Jiang Beihe's purpose was, Li Shenzhou had already made up his mind that if he really wanted to kill people with a knife to deal with Xiaoman, then he would not be polite to him, and there were many disciples of the Seven Killing Hall who died in their hands, and he had a way to kill them without a trace.

Early the next morning, Li Shenzhou went out of Dongping City with Lu Xiaoman and Xiaoxiao, and the Zhongpin Spirit Stone Mine was in the Cuiyan Mountain Range, four hundred miles west of Dongping City, and the demon beast mount provided by the branch hall only took about an hour to arrive there.

Originally, this spirit stone mine and the Cuiyan Gate of the three major second-rate sects in Dongping County happened to be in the same Cuiyan Mountain, and they were not far from each other for a hundred miles, and this spirit stone vein was also discovered by the Cuiyan Sect at the beginning, but how could a small second-rate sect keep such a precious property? At that time, the Dongping Sword Sect was only a second-rate sect, but even so, the Cuiyan Sect was the weakest of the four major sects.

However, they were also interested, and before they were discovered, they told the news to the branch hall of the Seven Killing Hall set up here, although the branch hall master here at that time was only a cultivator of the third or fourth layer of Ning Yuan, but there was a big backer of the Seven Killing Hall behind it, and even if the other three sects knew about it, they dared to have a trace of greed? Don't forget that the Seven Killing Hall has always been a demon sect, and it is easy to kill people and destroy the existence of the sect.

But because of the merits of offering treasures, since then, the Seven Killing Hall has also been taking care of this Cuiyan Gate, and has slowly grown into the head of the three second-rate sects, and the highest cultivator in the door is also the head of the Cuiyan Gate, Liu Yongnian, who is now the seventh layer of the Ning Yuan Realm, and the entire Dongping County except for the elderly Song Ning is the highest cultivator.

And this spirit stone mine is relatively close to the Cuiyan Gate, so the strength of the people stationed here is not very high, in addition to a group of guards on the sixth or seventh floor of the foundation realm, on weekdays, there is only one deputy hall master of the ninth floor of the foundation building realm who takes turns to guard. After all, no one would dare to come here to go wild unless they were bold outlaws.

It's just that this time is different from the past, so Lu Xiaoman will be sent here to garrison.

But the sect is only doing this to deter some young people, if there is really a first-class sect attacking, it will definitely retreat directly, as for whether to give up or settle accounts after the autumn, it depends on the situation of the war between the alliance and the three sects of the righteous path.

As for the mining workers in the spirit stone mine, they are all some martial artists of the third or fourth layer of the quenching realm, this is not that the dignified Seven Killing Hall can't get people, after all, as a demon gate, even if you catch it, you can catch a bunch of masters and come back to work as coolies.

It's just that if the true qi is used in the spirit stone mine, it will affect the spiritual power convergence of the natural formation in it, and then affect the output and regeneration of the spirit stone, so it can only be done by these martial artists who don't know true qi.

Fortunately, the spirit stone mine is not too hard, and it is not difficult to excavate.
