"Then I'm not polite?"

To be honest, Song Tianyu couldn't bear to leave these spirit stones. You should know that although spirit stones are common currency in the world of cultivators, they are extremely intimate cultivation resources. Most of the transactions in the world of cultivators are bartered, and only some very expensive items will be traded using spirit stones.

With these seven spirit stones in hand, and with the merit rewards of this spirit stone vein reported to the sect this time, if Song Tianyu really gets the opportunity to advance to the Qi training stage, then he would not have had the spiritual stone practice in the early stage of Qi training.

"Old Song, if you are polite, I may regret it." Fang Yi smiled and waved his hand, saying, "You have made arrangements with Song Gen. Don't let him pick me up in three days. I'll leave by myself."

According to Fang Yi and Song Tianyu's discussion, when reporting to the sect, Song Tianyu would make it clear that the two left together, which would save Fang Yi a lot of trouble, so he should say hello to Song Gen in advance to avoid any mistakes at that time.

"Okay, there's no need to worry about Song Gen. He will definitely listen to what I'm telling."

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

Song Tianyu knew that the sect had a lot of experience in mining spirit stones. It might not be possible to hide seven spirit stones from the mine he dug. The best way is to let the mine collapse. Even if they can clear the mine channel in the future, in the chaos of the qi, the sect would not have thought of finding out how many spirit stones had been released there.

"Will you have to do that? Is it a bit like there is no silver here?"

Hearing Song Tianyu's words, Fang Yi couldn't help but shake his head. It was not difficult to use explosives to knock down the passage, but the traces of covering up were too obvious. Fang Yi believed that the cultivators who came here later would not be fools, and would not be able to see at all?

"Fang Yi, it is common for the spiritual stone vein to collapse. At that time, you bury the explosives above the surface of the mine. As long as you explode on it, the lower part will be shaken down." Song Tianyu stayed in the world of cultivators for several years. Although he had never been to the spiritual stone vein, he knew a lot about related matters.

Since spirit stones are originally an energy body, although the energy scattered is very small, it is difficult to release it in a closed environment. Over time, it is easy to explode caused by energy collapse.

As far as Song Tianyu knows, almost all those who mine spirit stones in the world of cultivators risk their lives. There are countless people who die under the collapse of the spirit stone veins every year. Therefore, Song Tianyu's idea came up with just the understanding of people from the world of cultivators.

"Okay, then I'll do what you said." Fang Yi nodded, heard the sound of the engine outside, and hid into the house, saying, "Just tell Song Gen that I've left."

Song Tianyu told his nephew Fang Yi that he had entered the mine again when the car left. After three days of mining, the little diesel stored in the mine had long been used up, and the mine seemed extremely dark and shattered.

Unlike the shattering stones that were shattered from the mine tunnel by stone crusher before, Fang Yi, who was standing in the mine tunnel that Song Tianyu dug out, was empty-handed. He opened his mouth and a dazzling white leg suddenly appeared in the dark mine tunnel.

Without Song Tianyu beside him, Fang Yi was finally able to use his own means. Fang Yi, who entered the middle stage of Qi training, consumed almost tiny spiritual consciousness to control the flying sword, especially this is his natal flying sword, which is even more like an arm to use the fingers without any hindrance.

The frozen soil and kimberlite underground in Siberia are very hard. Using a stone crusher, you can only remove some small stones and soil from the mine tunnel bit by bit. However, under Fang Yi's natal flying sword containing a trace of spiritual power, the hard rocks and frozen soil suddenly became as unbearable as tofu.

It took Song Tianyu three days to dig a mine for more than 40 meters. At this moment, Fang Yi only took less than two hours to turn the mine into a huge space with a length and width of 60 meters. During these two hours, Fang Yi was just digging holes and was constantly picking up spirit stones.

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

As many spirit stones were discovered, Fang Yi also found experience. The direction he mined now was that a spirit stone would appear almost every few meters, and the quality of the spirit stone was gradually improving.

At the beginning, the spirit stones Fang Yi mined were only the size of a thumb, all of which were low-grade spirit stones, which were slightly worse than the low-grade spirit stones that Fang Yi had obtained before. However, the four or five spirit stones he collected recently were as big as the thumb, and the spiritual energy inside became more and more pure.

"It's not very difficult to mine spirit stones. Why does the world of cultivators need to use so much manpower?"

Fang Yi is getting stronger and stronger now. No matter how many spirit stones are, he doesn’t think there are too many, because whether it is cultivation or alchemy, spiritual stones must be used. At this time, when the spiritual energy of heaven and earth is lacking, the number of spirit stones directly determines the speed of cultivation.

Fang Yi had heard Song Tianyu talk about the mining of spiritual stones in the Cultivator Realm, but in his opinion, the big guys in the Cultivator Realm were a bit of a big deal. With the cultivation of a middle-level Qi cultivation practitioner, Fang Yi, he could mine spiritual stones so quickly. How could a spiritual stone ore vein be used to mine thousands of people?

But Fang Yi didn't know that the earth's space and the cultivator realm are two completely different spaces. The mass in the space is also very different. The cultivator realm that contains spiritual energy is nourished by spiritual energy. How can its mass be compared to the earth?

If Fang Yi releases spirit stones from the ore veins in the cultivator realm, the result will be that in less than half an hour, his precious natal flying sword will probably be destroyed. Even a rich and powerful foundation-building cultivator would not dare to mine a spirit stone vein like this.

Of course, if you are a great person with great ability to penetrate the world with cultivation, it will naturally be different. Legend has it that cultivators above the Nascent Soul stage can run over the sea with their hands. A spirit stone ore vein may be able to collect it with their hands raised. However, there seems to be no cultivators in the Nascent Soul stage in the world of cultivators in the past thousand years. It is impossible to prove whether this rumor is true or false.

"Huh? The stones in this place seem to be much harder?"

Fang Yi felt a little mentally exhausted after using the flying sword continuously. After resting for a while, he continued to dig. However, 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 training stage and the innate one is to transform a body of innate energy into spiritual power. Fang Yi is now just a cultivator at the fourth level of Qi training, which means that he only has four meridians to store spiritual power. After all the eight extraordinary meridians on Fang Yi’s body are opened, he will successfully attack the last hidden meridian and become a cultivator at the Foundation Establishment stage.

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

The consumption of spiritual power is not the main reason why Fang Yi stopped. The most important thing is that he found that as the excavation deepened, the kimberlite rock became hard, the quality of some diamonds produced was getting higher and higher. Those high-quality diamond ore were far more than spiritual stones, and Fang Yi had 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 be cut open, but with more numbers, the other party's natal flying sword still causes minor damage.

"After returning, you slowly nourish it, the flying sword can be automatically restored, but there is no place to find the spirit stone."

Looking at his flying sword with some distress, Fang Yi took out a spirit stone to absorb spiritual energy, and made a decision in his heart. Although the flying sword in his natal is precious, it can be repaired. However, if the spirit stone is missed, there will be no such store. Fang Yi will not know where to find it in the future.

If you can restore spiritual power through cultivation, Fang Yi will probably have to practice for ten days and a half months in this place where spiritual energy is scarce, but using spirit stones to recover will increase much faster. As the traces of spiritual energy in the spirit stones are sucked into Fang Yi's body, the spiritual power in his meridians will soon be enriched.

More than an hour later, Fang Yi put away the spirit stones and continued to control the flying sword to dig. At this time, the number of spirit stones in his mustard bag had reached 35. He always thought he was Fang Yi, who had no desires and no desires. This time he was really red, and he didn't even care about the damage of the rice grains on the flying sword.

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

Suddenly, Fang Yi, who bent down to pick up the spirit stone, showed an unbelievable look in his eyes, because he found that this spirit stone as big as a baby's palm contained extremely pure spiritual energy. Fang Yi subconsciously absorbed a little, and the almost dry meridians in his body quickly replenished their spiritual power.

"Is this a medium-grade spirit stone?"

Fang Yi stared at the spirit stones in his hand tightly. He knew that the spirit stones were divided into three grades: top-grade and upper-middle-lower-lower-grade spirit stones. The spiritual energy reserves in the lower-grade spirit stones are small and impure, and are usually only suitable for practitioners in the Qi training stage and the Foundation Establishment stage. Cultivators above the Foundation Establishment stage need to practice with higher purity medium-grade spirit stones.

However, medium-grade and high-grade spirit stones are extremely rare even in the world of cultivators. It is said that only hundreds of medium-grade spirit stones and dozens of high-grade spirit stones can be mined in a high-yield spirit stone. As for the best-grade spirit stones, they are hard to come by, and not every spirit stone vein can appear.

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

Fang Yi's hand holding the spirit stone trembled slightly. At this moment, he felt like he had gone from a bitter peasant to a landlord to become a landlord, and he felt like a serf turned over and sang.

"It is impossible that there is only one medium-grade spirit stone, there must be one."
