"It seems that the aura on the earth has not completely disappeared, at least there are still some underground. ”

Picking up another medium-grade spirit stone from the ground, Fang Yi's face was about to bloom, more than two days of mining, so that Fang Yi had obtained a total of more than two hundred lower-grade spirit stones and more than thirty medium-grade spirit stones, and now his mustard seed bag was almost all filled with spirit stones.

This also made Fang Yi think about it, although there was no aura in the air on the surface of the earth, but in the ocean and underground, there was still aura existence, and the closed environment made the flow of aura slow down, the Arctic ice cave was like this, and the ore spirit vein in front of him should be formed in the same way.

Fang Yi has basically been alone since he entered the Dao, he has never enjoyed the benefits of his master, he is really poor, he is not too many spirit stones, so he has almost been sleepless in the past two days, and has become a happy little miner in the mine.

"Huh?"

Just as Fang Yi used the flying sword to clear out a rock wall, his complexion suddenly changed, and his heart couldn't help but be shocked, and he hurriedly used his divine sense to control the flying sword to come to the front, and when he fixed his eyes, Fang Yi suddenly felt distressed, because on his natal flying sword, there was a gap that was much larger than a grain of rice.

Fang Yi's plane, but it was refined with divine sense, and it has been kept in the dantian to cultivate, it can be said that it is connected to his mind, the damage of the flying sword before was small, and Fang Yi didn't feel anything, but this time, it made Fang Yi's mind feel a little implicated, and it felt like being hit hard in the chest.

"You can't continue mining with flying swords. ”

Taking a few deep breaths, Fang Yi adjusted the slightly disordered qi in his body, he found that after the flying sword was damaged this time, he used his divine sense to direct the flying sword, and he felt a trace of stagnation, Fang Yi knew that if he continued, it was likely to cause the flying sword to be unable to be repaired.

"Immeasurable Heavenly Venerable, you can't use a flying sword, you can use a stone crusher. ”

Fang Yi put the flying sword into the dantian Yun and raised it, and was about to go back to find the stone crusher when he turned around, but as soon as he turned around, Fang Yi suddenly turned his head back suddenly, "What did you dig up just now? ”

Fang Yi didn't think so much about the flying sword before, and he didn't feel the aura of the spirit stone overflowing around his body, but at this moment, Fang Yi reacted, it was a flying sword infused with his own spiritual power, even if it was a diamond, it was impossible for the flying sword to be damaged so badly.

Thinking of this, Fang Yi hurriedly squatted down and rummaged through the pile of rocks on the ground, just lifting a stone, Fang Yi suddenly narrowed his eyes, because under the stone, a dazzling blue light was revealed.

In the mine where he couldn't see his five fingers, Fang Yi basically used his divine sense to see things, this sudden blue light made Fang Yi's eyes a little uncomfortable, he covered his eyes with his hand, and Fang Yi's divine sense observed the luster.

"This, is this also a spirit stone, why is there no aura?"

The blue light was emitted by a piece of jade the size of a baby's fist that exuded a faint blue hue all over its body, but Fang Yi's divine sense found that this blue jade did not have the slightest aura leakage, and from the outside, it was just like a blue stone.

Reaching out to pick up the blue jade, Fang Yi pinched it heavily, but his two fingers hurt when he pinched it, and the jade did not change, Fang Yi understood, this jade should be the culprit who damaged his natal flying sword.

"What kind of thing is this, how can it be so hard?" Fang Yi looked at the jade stone in puzzlement, his heart moved, and he started the exercises, and a suction force suddenly came out of Fang Yi's palm.

"Hmm, this, what kind of aura is this?!"

Fang Yi only made some attempts, and didn't expect to be able to absorb the aura from the jade, but what he didn't expect was that with the operation of the exercises, a trace of aura was sucked into his body along with the meridians on Fang Yi's arm.

Compared to the more docile aura in Fang Yi's previous cultivation and use of spirit stones, this trace of aura was extremely cold, after entering his body along Fang Yi's meridians, Fang Yi only felt that half of his body seemed to be frozen, and he couldn't even move a finger.

In order to resist this cold, the spiritual power in Fang Yi's body spontaneously operated, wanting to expel this trace of spiritual energy, but for some reason, this trace of spiritual energy was actively integrated into Fang Yi's spiritual power, walking within the eight veins of the strange meridians in Fang Yi's body.

"Click!"

After that trace of spiritual power was completely integrated, Fang Yi suddenly heard a soft sound in his chest, as if something had been opened, and after a careful sense, Fang Yi's face couldn't help but show a strange look, because he found that he didn't do much, the fifth meridian in his body had been opened, and he was now a fifth-level cultivator in the Qi cultivation period.

And after the breakthrough, the meridians in Fang Yi's body were also swollen and uncomfortable, at this moment, that trace of aura suddenly wrapped around the natal flying sword contained in the dantian, Fang Yi, who was in a state of inner vision, clearly saw that his damaged natal flying sword was being repaired quickly.

After about four or five hours, the swollen feeling of Fang Yi's meridians gradually disappeared, and the cold breath was completely fused with the spiritual power in his body, stretching his arms and legs, Fang Yi found that he knew that he could truly move freely at this time.

"Immeasurable Heavenly Venerable, what's going on?"

Fang Yi's face was inexplicable, although he had repeatedly exhausted his aura in the mine for the past two days and then replenished it, making some progress in his cultivation, but there was still a certain gap between him and the fifth layer of the Qi cultivation period, Fang Yi didn't expect it, just fused with a trace of aura containing a cold aura, he actually broke through.

"What level of spirit stone is this?, is it a high-grade spirit stone?" Looking at the spirit stone in his hand, Fang Yi's eyes showed a thoughtful look, although the trace of aura just now contained a cold aura, the purity of the aura was also something Fang Yi had never seen before.

However, Fang Yi didn't dare to try again now, because he had a feeling that if he absorbed the aura in this blue jade again, the meridians in his body would definitely burst open because he couldn't bear it, and with his current cultivation, dissolving that trace of aura was already at its limit.

"Could it be that this is the best spirit stone, so it has that cold aura?"

Fang Yi's face looked a little cloudy under the blue glow, he did know some grades of spirit stones from Song Tianyu and Le Kai and others, but the upper, middle and lower grade spirit stones didn't seem to match the characteristics of this spirit stone.

In fact, Fang Yi mistook the spirit stone in his hand for a top-grade spirit stone, but he thought about it, this was just a high-grade spirit stone, the reason why Le Kai and Song Tianyu didn't mention it was because they had never seen a high-grade spirit stone, they just heard it from others with false rumors.

In the cultivator world, the lower grade spirit stone is the most common, and the most produced in the spirit stone vein is the lower grade spirit stone, and the lower grade spirit stone can be used to cultivate during the qi training period, but the spiritual energy in the lower grade spirit stone is somewhat mixed and impure, and the reserves of spiritual energy are relatively small, which is not enough for cultivators in the qi training period to cultivate for a long time.

Qi cultivation stage cultivators can use medium-grade spirit stones to cultivate, and the effect is much better than that of lower-grade spirit stones, but the number of middle-grade spirit stones in the cultivator world is extremely small, that is, many foundation building stage elders may not be able to allocate a few pieces, which is undoubtedly a luxury for ordinary cultivators.

Medium-grade spirit stones and low-grade spirit stones will exude a faint aura to the outside world, but only the top-grade spirit stones lock the aura tightly, unless there is an external force to absorb it, otherwise the aura in the top-grade spirit stones will not overflow.

However, the number of high-grade spirit stones is extremely small, and a vein of spirit stones with rich reserves can only be mined out of one or twenty pieces, and there are only a few pieces or none of them, and not many people have seen them at all, and even if they are mined, they will be immediately sent to the sect for proper preservation, and ordinary disciples will not see them at all.

It was because Song Tianyu and Le Kai didn't know that the top-grade spirit stone contained attributes, and the aura in the spirit stone fit the five attributes of gold, wood, water, fire, and earth, and if they wanted to absorb the extremely pure aura in the top-grade spirit stone to cultivate, they must reach the foundation building period.

Although cultivators with different spiritual root attributes and above the foundation building period can use high-grade spirit stones to cultivate, if there is a high-grade spirit stone that matches the attributes, the speed of cultivation is undoubtedly much faster than that of high-grade spirit stones with inconsistent attributes.

Moreover, the top-grade spirit stone also has an effect, that is, after the cultivation reaches the peak of the qi cultivation period, taking the Zhuji Dan and using it with the top-grade spirit stone can use the pure spiritual energy in the top-grade spirit stone to wash the meridians and increase the probability of success in foundation building.

However, the top-grade spirit stone is precious and abnormal in the cultivator world, and once it is mined, it is sent to the ancestors of the major sects in the cultivator world hidden behind the scenes, and even the head of the sect has no chance to use it, let alone ordinary disciples, many cultivators in the foundation building period of small sects have never even seen the top-grade spirit stone.

"If you can meet Master in the future, you must ask Master what level of spirit stone this is. ”

Although he couldn't see through the spirit stone in his hand, Fang Yi knew that it must be a good thing, and he must not show it easily, thinking of this, Fang Yi hurriedly put away the spirit stone in his hand, as if this cave man still had others.

"The flying sword can't be used for the time being, so let's use a stone crusher, anyway, the time is almost up, dig for half a day and leave!"

After putting away the spirit stone, Fang Yi estimated the time, it was almost three days, Fang Yi didn't want to be blocked by the people of Song Tianyu's sect in the mine, even if he was unwilling, Fang Yi knew that he had to leave as soon as possible.

Using a stone crusher to excavate, the speed was extremely slow, and it took half a day for Fang Yi to dig up a medium-grade spirit stone, knowing that he couldn't delay any longer, Fang Yi returned to the ground and buried the explosives above the mine he had dug out.

After a loud bang, the explosives did not cause much movement on the hard tundra, but only a crater several meters square.

But after going down to the mine to check, Fang Yi found that the mud on the rock wall above the mine road he and Song Tianyu had completely collapsed, and even if it took several times the effort to clean it up again, he would not see the traces they left before.

"Hehe, buddy has eaten meat, as for how much soup is left, then I don't care. ”

After filling in the hole in the ground, Fang Yi took out a map left by Song Tianyu and looked at it and floated away, he was not ready to leave Siberia through Song Gen, but wanted to go directly through the Sino-Russian border to return to China.

In fact, Fang Yi still thought about this spirit stone vein simply, although the aura of heaven and earth disappeared on the earth, and the spiritual energy of the vein continued to flow and the number of spirit stones decreased, but this vein still had thousands of low-grade spirit stones and hundreds of medium-grade spirit stone reserves.

However, the top-grade spirit stone, among this vein, there was really only the one that Fang Yi obtained, but this was because in the endless years, the veins without spiritual energy nourishment could only draw spiritual energy from the top-grade spirit stone, and the top-grade spirit stone almost completely disappeared.
