"Then you're welcome?"

To be honest, Song Tianyu was reluctant to let go of these spirit stones, you must know that although spirit stones are a common currency in the cultivator world, they are extremely scarce cultivation resources, and most of the transactions in the cultivator world are barter, and only some very valuable items will be traded with spirit stones.

With these seven spirit stones in his hands, coupled with the meritorious reward of reporting this spirit stone vein to the sect this time, if Song Tianyu can really get the opportunity to advance to the qi training period, then he will not be able to cultivate without spirit stones in the early stage of qi training.

"Old Song, if you are polite again, I may regret it. Fang Yi smiled and waved his hand, and said, "Song Gen, you make arrangements, don't let him pick me up after three days, I'll just leave by myself then." ”

According to Fang Yi and Song Tianyu's discussion, when reporting to the sect, Song Tianyu would indicate that the two of them were leaving together, which would also save Fang Yi a lot of trouble, so he had to greet Song Gen in advance to avoid any mistakes or omissions at that time.

"Okay, don't worry about Song Gen, he will definitely listen to what I say. ”

Song Tianyu hesitated for a moment, then said, "Fang Yi, when you leave, can you blow up that mine road? There are explosives in this mine, and it should be no problem to blow up that section of the mine road."

Song Tianyu knew that the sect had a lot of experience in mining spirit stones, and he had mined seven spirit stones in the mine he dug up, and he might not be able to hide them, so the best way was to let the mine collapse down, even if they could clean up the mine in the future, under the chaos of the qi machine, the sect would not want to find out how many spirit stones had come out there.

"If you do that, will it be a little bit of a silver three hundred taels here?"

Hearing Song Tianyu's words, Fang Yi couldn't help but shake his head, it wasn't difficult to use explosives to collapse that passage, but the traces covered up by doing so were too obvious, Fang Yi believed that the cultivators who came here in the future were not fools, and they wouldn't be able to see it at all?

"Fang Yi, it is a common occurrence for the spiritual stone vein to collapse, when the time comes, you bury the explosives above the surface of the mine, as long as the top explodes, the bottom will be collapsed. "Song Tianyu has been in the cultivator world for a few years, and although he has never been to the spirit stone vein, he knows a lot about related things.

Since the spirit stone is a kind of energy body, although the energy that overflows is very small, it is difficult to release it in a closed environment, and over time, it is easy to explode caused by the collapse of energy.

As far as Song Tianyu knew, almost all of the people in the cultivator realm who mined spirit stones had to risk their lives, and the number of people who died under the collapse of the spirit stone veins every year was unknown, so Song Tianyu's idea was just in line with the cognition of people from the cultivator realm.

"Okay, then I'll do as you say. Fang Yi nodded, heard the sound of the engine outside, and hid into the room, and said, "You just tell Song Gen that I'm gone." ”

Song Tianyu explained to his nephew Fang Yi that when the car left, he had re-entered the mine, after three days of mining, the little diesel fuel stored in the mine had already been used up, and the mine seemed extremely dark and broken.

Unlike before, when a stone crusher was used to crush stones from the mine tunnel piece by piece, Fang Yi, who was standing in the mine tunnel dug by Song Tianyu at this time, was empty-handed, only to see him open his mouth and spit out, and a dazzling white practice suddenly appeared in the dark mine tunnel.

Without Song Tianyu by his side, Fang Yi was finally able to use his own means, Fang Yi, who had entered the middle stage of Qi training, the divine sense consumed to control the flying sword was almost minimal, especially since this was his natal flying sword, it was even more like an arm and finger to use, without the slightest hindrance.

The frozen soil and kimberlite under Siberia are very hard, and the stone crusher can only remove a small number of stones and soil from the mine little by little, but under Fang Yi's natal flying sword that contains a trace of spiritual power, this hard rock and frozen soil suddenly became as unbearable as tofu slag.

Previously, it took Song Tianyu three days to dig out a mine road of more than forty meters, but at this moment, Fang Yi only took less than two hours to turn this mine road into a huge space with a length and width of sixty meters, and in these two hours, Fang Yi was just digging holes, and he was constantly picking up spirit stones.

"The direction chosen by Lao Song seems to be the direction of the spirit stone vein. Fang Yi's face was full of joy in the dark, and the mustard seed bag around his waist had already contained seventeen or eighteen spirit stones, and this was only a harvest of more than two hours.

There are more spirit stones to discover, Fang Yi has also found out the experience, the direction he is mining now, almost every few meters there will be a spirit stone, and the quality of the spirit stone is gradually improving.

At the beginning, the spirit stones mined by Fang Yi were all just the size of a thumb's belly, and all of them were low-grade spirit stones, which were slightly inferior to the low-grade spirit stones that Fang Yi had obtained before, but the four or five spirit stones that had been mined recently were the size of a thumb, and the aura inside was becoming more and more pure.

"It's not too hard to mine spirit stones, why does the cultivator realm need to use so much manpower?"

Fang Yi is now getting more and more energetic, no matter how many spirit stones are for him, no matter how many spirit stones are too much, because whether it is cultivation or alchemy refining, he must be able to use spirit stones, at this time when the spiritual energy of heaven and earth is missing, the number of spirit stones directly determines the speed of cultivation.

Previously, Fang Yi had heard Song Tianyu talk about the cultivation of spirit stones in the cultivator realm, but in his opinion, those bigwigs in the cultivator realm were inevitably a bit of a fuss, with the cultivation of a cultivator in the middle stage of Qi cultivation like Fang Yi, he could mine spirit stones so quickly, where could a spirit stone vein be mined by thousands of people.

It's just that Fang Yi didn't know that the earth space and the cultivator realm were two completely different spaces, and the quality in the space was also very different, the cultivator realm that contained the spiritual energy, every stone and tree was nourished by the spiritual energy, how could its quality be compared to the earth?

If Fang Yi released the spirit stone in the vein of the cultivator realm, then the result would be that it would not take half an hour, and his precious natal flying sword would be destroyed, even if it was a wealthy foundation building stage cultivator, he would not dare to mine a spirit stone vein like this.

Of course, if it is the kind of person who cultivates to penetrate the heaven and earth, it is naturally different, it is said that cultivators above the Yuan Infant Stage can be overwhelmed by turning their hands, and a spirit stone vein is afraid that they can collect it with a raise of their hands, but in the past thousand years, there seems to be no cultivator in the Yuan Infant Stage in the cultivator world, and it is impossible to confirm whether this rumor is true or not.

"Huh, the stone in this place seems to be much harder?"

Using the flying sword non-stop, Fang Yi also felt a little mentally tired, and only continued to dig after resting for a while, but after starting work this time, Fang Yi found that he needed to inject more spiritual power into the flying sword.

The difference between the Qi cultivation period and the innate Qi is that he has to transform his innate qi into spiritual power, Fang Yi is now only a cultivator of the fourth layer of Qi training, that is to say, he only has four meridians that can store spiritual power, and when all the eight veins of the Qi Sutra on Fang Yi's body are opened, he can successfully impact the last hidden vein before he can become a cultivator in the foundation building period.

After increasing the output of spiritual power to the flying sword, this time Fang Yi had to stop after only mining for more than an hour, not because Fang Yi's divine sense was not enough, but because the spiritual power in his body was actually consumed.

And the consumption of spiritual power was not the main reason why Fang Yi stopped, the most important thing was that he found that as the excavation deepened, the kimberlite became hard, not to mention, the quality of some of the diamonds produced was also getting higher and higher, those high-quality diamond raw ore was far more than the spirit stone, Fang Yi had already collected hundreds of them.

Diamonds are actually high-quality and high-purity diamonds, and diamonds are one of the hardest objects in the world, even under Fang Yi's Natal Flying Sword, those diamonds can also be cut, but there are too many of them, and Fang Yi's Natal Flying Sword still caused slight damage.

"After going back, slowly cultivate, the flying sword can be automatically recovered, but the spirit stone is nowhere to be found. ”

Looking at his flying sword with some distress, Fang Yi took out a spirit stone to absorb the spiritual energy, and made a decision in his heart, although the natal flying sword is precious, but it can be repaired, and the spirit stone is that if you miss this village, there will be no such shop, and Fang Yi will not know where to find it in the future.

If the spiritual power was restored through cultivation, in this place where spiritual energy was scarce, Fang Yi was afraid that he would have to cultivate for ten days and a half months, but using the spirit stone to recover, the speed would be much faster, and as the trace of spiritual energy in the spirit stone was inhaled into Fang Yi's body, the spiritual power in his meridians was quickly enriched.

After more than an hour, Fang Yi put away the spirit stones and continued to control the flying sword to excavate, and at this time, the number of spirit stones in his mustard seed bag had reached thirty-five, Fang Yi, who had always thought that he had no desires, this time his eyes were really red, and he couldn't even care about the damage the size of a grain of rice on the flying sword.

"This, this is definitely not a low-grade spirit stone?"

Suddenly, Fang Yi, who leaned down to pick up the spirit stone, showed an unbelievable look in his eyes, because he found that this spirit stone, which was the size of a baby's palm, contained extremely pure spiritual energy, Fang Yi subconsciously only absorbed a little, and the almost dry meridians in his body were quickly filled with spiritual power.

"Could it be that this is a medium-grade spirit stone?"

Fang Yi's eyes stared at the spirit stone in his hand, he knew that the spirit stone was divided into the best grade and the upper, middle and lower grades, the spiritual energy reserves in the lower grade spirit stone were small and impure, usually only suitable for cultivators in the Qi cultivation period and the foundation building period, while cultivators above the foundation building period needed to use medium-grade spirit stones with higher purity to cultivate.

However, medium-grade and high-grade spirit stones, even in the cultivator world, are extremely rare, it is said that in a high-yield spirit stone vein, only hundreds of medium-grade spirit stones and dozens of high-grade spirit stones can be mined, as for the best spirit stones, it is even more rare to find, not every spirit stone vein can appear.

"This medium-grade spirit stone is equivalent to hundreds or even more low-grade spirit stones. ”

Fang Yi's hand holding the spirit stone trembled slightly, this would make him feel like he had become a landlord from a bitter peasant who had become rich overnight, quite a bit like a serf turning over and singing.

"It can't be that there is only one medium-grade spirit stone, there must be one. ”

Fang Yi's eyes were almost red, after collecting the spirit stones, he continued to mine, around the space where the medium-grade spirit stones were found, Fang Yi spent a whole day, and successively mined more than twenty spirit stones, all of which were medium-grade spirit stones.
