It wasn't until Li Shenzhou saw this spirit stone mine cave with his own eyes that he suddenly realized that he had overlooked something.

The rich heaven and earth aura in this spirit stone mine cave was even several times higher than Lu Xiaoman's cultivation room for core disciples in the sect, and this was only a mid-grade spirit stone vein!

"Yes, it is also the spiritual power of the earth veins to gather the spiritual energy of heaven and earth, but the spiritual energy in the cave heaven blessed land like the sect is overflowing in the air and used by the people of the ** sect, and the spirit stone mine is injected into the ore to form the spirit stone. Li Shenzhou suddenly realized that although these two final forms were different, they would gather a large amount of heaven and earth aura in the process.

In fact, the method of artificially making spirit stones has long been invented by people to imitate the travel process of spirit stone veins, but ordinary spirit gathering arrays can only be refined with spirit stones and other materials, and there will be a loss process in the middle, so no one will use this way to make spirit stones.

Only the spirit gathering array formed based on the earth's vein aura will be more cost-effective, but the place where the earth's leyline aura is rich in this middle region is not a place suitable for establishing sects, families and other power mountain gates such as the Cave Heaven Blessed Land, or the spirit stone veins have been formed or there are some heavenly and earthly treasures.

And in this kind of cave blessed land suitable for the establishment of mountain gates, unless there is an extreme shortage of money, no one will be stupid enough to bother to find a large amount of ore and inject spiritual energy into it, just to form spiritual stones, which will not only take a long time, but also seriously affect the level of spiritual energy in the mountain gate, and then affect the overall cultivation speed of the disciples of the sect, after all, the cultivation strength of this world is the most important, otherwise it will be like the green smoke gate, and the treasure is in front of him, and he is unable to possess it, so he can only obediently give it to others.

Of course, if it is a mineral vein formed in the depths of the earth, unless there are a few sects with special hobbies or special cultivation methods, no one will build the mountain gate here? And this also has to consider the safety of the mountain gate, compared to the mountain gate built on the famous mountain and river, if the underground cave palace is not strong enough to protect the formation, it is too easy to be destroyed, any large-scale attack can easily collapse the mine, so that the martial artist who cultivates in it will die directly without a chance to resist and escape.

It's like a kitchen knife can be used to chop vegetables or kill people, but killing people with a kitchen knife is certainly not as convenient and easy to use as a gun. Therefore, most of the spirit stone veins that have been discovered are only used to mine spirit stones, which is already a mode of thinking formed by the human race for more than 100,000 years.

If you want Li Shenzhou to choose, if you can cultivate in a beautiful environment where the four seasons are like spring, birds singing and flowers are fragrant, you won't go to the dark and cold bottom, but if the concentration of aura here is very high, then it's another matter.

As for the fact that this would destroy the formation of the spirit stone, Li Shenzhou didn't care at all, after all, he wanted the spirit stone itself to assist Lu Xiaoman and Xiaoxiao in cultivation, not for setting up array refining tools or selling them. Therefore, cultivating directly here actually eliminates a procedure.

In an instant, an impulse arose in Li Shenzhou's heart to find an ownerless or directly seize a high-grade spirit stone mine, as far as he knew, in Nanyang County, which was not too far away from Dongping County and was also controlled by the Seven Killing Palace, there was a spirit stone mine with an annual output of about 300 high-grade spirit stones.

You must know that the loss in the process of transforming the spiritual energy into the spiritual stone in this naturally formed spiritual stone mine is not small, in terms of the amount of condensed spiritual energy, the spiritual stone is only equivalent to one-fifth of it, so the annual spiritual energy gathered by it alone is enough to be equivalent to 1,500 high-grade spiritual stones, which is a huge resource.

However, it is easy to grab it, but it is difficult to hold it, even if Li Shenzhou's strength is strong, it is impossible to frequently consume the origin to fight.

However, the medium-grade spirit stone mine they are stationed there now has a chance to succeed, although it is only equivalent to four thousand medium-grade spirit stones, that is, the spiritual energy released by forty high-grade spirit stones, but it is also higher than the core disciple cultivation room, isn't it?

Li Shenzhou was already prepared to slowly accumulate cultivation over time after the spirit stones were exhausted, so a good environment was extremely important, and the time saved after accumulation was also a lot.

"It just so happens that this Dongping Sword Sect is coming to rob it, and when the time comes, you can use their hands to pretend to destroy this mine!" Li Shenzhou thought about it and came up with a thought, after that, there should be someone to investigate, but Li Shenzhou also has a way to deal with it, and now he is just waiting for the arrival of the Dongping Sword Sect.

A few days were spent in calm cultivation, Lu Xiaoman and Xiaoxiao were very relieved, because if the Dongping Sword Sect attacked the Mortal Realm, they would definitely have to make a move, and at that time, only Li Shenzhou could deal with it, and it didn't make sense for them to make a move, so of course they were relieved to have Li Shenzhou guarding them.

However, she hesitated to enter the deep retreat, so the feeling of time passing was still clear, and after a few days of perseverance with Xiaoxiao's out-of-the-box temperament, she had to play and relax, and Li Shenzhou let her go

"Master! I found that Jiang Yuhe! He sneaked into the mine, I don't know what to do!"

Li Shenzhou, who was originally guarding the landing of Xiaoman, suddenly heard Xiaoxiao's consciousness transmission.

"You weren't discovered by him, were you?" Li Shenzhou frowned.

"Of course not!" Xiaoxiao said proudly, she is now also a third-level cultivator in the Ning Yuan Realm, and if you don't care about the hole cards in the same level, only an invincible spiritual existence like Lu Xiaoman, who is almost at the same level, can discover her in hiding.

"Follow up and see what he's doing!" Li Shenzhou immediately said, and at the same time separated half of his consciousness into Xiaoxiao's soul, one is to better observe and deal with the unexpected.

The entrance to the mine is naturally guarded, after all, the spirit stone is so precious, in order to prevent someone from sneaking in or the private possession of the warrior who is mining inside, it needs to be supervised by the guard.

However, with Jiang Yuhe's strength, even if he passed by them, these martial artists who were only at the fifth or sixth level of the Foundation Building Realm would not be able to detect his existence, and as for Xiaoxiao, it was even more so.

The two of them entered the mine one after the other in front of a dozen guards.

Although it was dark at this time, there were still laborers digging in the mine, but Jiang Yuhe released a colorless and odorless drug to stun these people after diving to a certain depth, which made people a little strange, with his strength, even if he killed all these people, he would not be noticed by the people outside.

However, Li Shenzhou didn't think too much about it at this time, and continued to follow Jiang Yuhe into the main mine, which was a cave the size of a football field, and there were some useless ordinary ores scattered on the ground, but these ores would not be thrown away, after all, as long as they were in this cave, these ores would have a chance to be converted into spirit stones.
