Gu Zhan's heart was hot, and he immediately changed to a storage bag, this time he took out the storage bag of the head of the Lunatic Sect, the head of the Lunatic Sect originally had three thousand spirit stones in the storage bag, and his net worth was more than that of Qiu Mo, but compared with Gu Zhan's harvest at this time, it was like the light of a grain of rice competing with the bright moon, and it couldn't be compared at all! Gu Zhan was busy from night to dawn, and he was only half loaded!

Moreover, when Gu Zhan was loading the spirit stones, he actually found that a spirit stone contained ten times the spiritual energy of ordinary spirit stones! Suddenly, these spirit stones should be the so-called medium-grade spirit stones, although the content of this spirit stone is only ten times that of ordinary spirit stones, but Gu Zhan knows that its value is far more than ten times that of ordinary spirit stones!

In the cultivation realm, the amount of aura contained in the lower-grade spirit stone and the middle-grade spirit stone is actually not a quantitative change, but a qualitative change! That is to say, there is almost no difference in the amount of spiritual energy contained in the two spirit stones, but the richness of each trace of spiritual energy in the latter is ten times that of the former!

Take Gu Zhan as an example, when he absorbs the aura emitted from ordinary spirit stones, he can swallow four spirit stones at the same time, if there is more, the aura produced by the stomach after digesting the spirit stones will greatly exceed Gu Zhan's absorption capacity, then those excess aura will directly overflow Gu Zhan's body, forming a huge waste.

However, the medium-grade spirit stones are different, because the spiritual energy contained in the medium-grade spirit stones is not a quantitative change, but a qualitative change! Gu Zhan can even swallow four medium-grade spirit stones at the same time, and he can still absorb 100% of them into his body, but because of the strengthening of the quality, he is equivalent to absorbing forty spirit stones in the time it takes to absorb four spirit stones!

Cultivators and Gu Zhan have the same effect of absorbing spirit stones, when they absorb medium-grade spirit stones, they are also equivalent to absorbing ten times the quality, these purer spiritual qi into true yuan, will be even larger, with the cultivation speed of a medium-grade spirit stone, it is also more than ten times that of the lower-grade spirit stone!

Even, the benefits of the medium-grade spirit stone to the cultivator are greater than Gu Zhan! Because of the enhancement of the concentration of the spiritual energy, the transformed true yuan is also more high-quality than the true yuan that is usually cultivated, which is invisibly equivalent to purifying the quality of the true element, and it has unspeakable benefits for impacting the bottleneck and promotion......

Therefore, in the monetary ratio of the cultivation realm, the value of one hundred lower-grade spirit stones is equivalent to one medium-grade spirit stone, and even so, few people use medium-grade spirit stones to exchange for lower-grade spirit stones.

When Gu Zhan saw this medium-grade spirit stone, he was even more excited, and vigorously searched for the remaining spirit stones in the spirit vein, and at the same time put the obtained middle-grade spirit stones and low-grade spirit stones into different storage bags, but when Gu Zhan scavenged out 90% of the spirit stones in the entire spirit vein, he found that he had only collected more than ten medium-grade spirit stones so far, and basically one medium-grade spirit stone could be produced out of 10,000 lower-grade spirit stones, and the probability was outrageous......

However, thinking that this is only a small spiritual vein after all, and the spiritual energy is not strong enough, so the output of medium-grade spirit stones is also relieved. If it is a medium-sized or even large-scale spirit vein, the probability of producing a medium-grade spirit stone is definitely much higher than here, and there is even a high-grade spirit stone!

It's a pity that this kind of small spiritual vein can't have that kind of precious thing at all.

However, just as Gu Zhan was about to put all the remaining spirit stones in the spirit veins into the storage bag, suddenly, the entire huge karst cave trembled slightly.

Gu Zhan was shocked in his heart, and the premonition of danger was released again in vain, and faintly, it seemed that some crisis was gradually approaching, like a chariot rolling in a thick fog, not seeing its shape, hearing its voice first!

The movement in Gu Zhan's hand paused, he squatted down solemnly, and pressed one hand on the ground, until this time, he could feel the ground trembling faintly, and as time passed, this tremor was gradually intensifying!

"The spiritual veins are loosened, and then, just like a flood bursting the embankment, the entire spiritual veins will completely collapse and be destroyed, and even the surface of the earth will not be able to escape alone. At this time, Huang Feng'er in the inheritance cave suddenly spoke. Gu Zhan had picked up spirit stones for a day and a night, while she meditated cross-legged in the cave and recuperated for a day and a night. At this time, her spirit was obviously better than yesterday, and even her mood seemed to have returned to normal, but her expression was extremely solemn.

Gu Zhan frowned suddenly, he looked at the swarthy exit in the distance, and reluctantly looked at the more than 10,000 spirit stones left, and then made up his mind and stretched out his hand, "In this case, you come out, I will take you out of here, otherwise you will not be able to leave with your current injuries." ”

Huang Feng'er was stunned for a moment, she looked at Gu Zhan in a daze, and she was stunned.

"What are you waiting for, if you don't leave, it'll be too late!" Gu Zhan said urgently.

"Do you think you can get away?" However, Huang Feng'er laughed in a low voice, she didn't make any movements, she just looked at Gu Zhan for a long time, and her expression was slightly soft.

"Since you're not leaving, I think it's your exit to say goodbye. Gu Zhan's expression sank, and he didn't urge anymore, he just turned around quickly, and his feet exploded towards the exit like an arrow from the string!

But before he could enter the previous passage, Gu Zhan's expression suddenly changed drastically! Because he heard a faint sound like ocean waves coming from the depths of the passage, and at the same time, the vibration of the entire spiritual vein became even stronger!

Gu Zhan's face was very ugly, and only then did he remember that there was a huge lake at the other end of the passage! At this time, the spiritual veins had been broken, so those water currents could no longer be blocked, and it was estimated that there was an incomparably huge water flow in the passage at this time!

"Or is it because of inexperience......" Gu Zhan smiled bitterly, he didn't expect this situation at all, but when he expected it, it was too late.

Obviously, Huang Feng'er had long known the consequences of this path, otherwise she would not have failed to loot these spirit stones, but she did not remind Gu Zhan at all.

Although he knew this, Gu Zhan did not have the slightest resentment against Huang Feng'er, after all, he had a hostile relationship with the other party before, and he even broke most of her bones, and he did not plan to give half of these spirit stones to the other party, and the two sides were not related to each other, so they really had no obligation to remind themselves.

Gu Zhan's expression was cloudy, every second, the trembling of the entire cave was intensifying, and the sound of the tide was more intense, obviously a large amount of lake water rushed here like the momentum of ten thousand horses galloping, with this kind of pressure, even if Gu Zhan had the strength of ten thousand jun, it was impossible to compete with the impact of the current!

Bang!

Just when Gu Zhan was thinking about other ways to escape, suddenly, a huge stalactite on the top of the cave fell down, making an earth-shattering roar! But this was just the beginning, and then, a huge stone fell from the top of his head, and in the blink of an eye, it was like a meteorite rain, Gu Zhan was busy dodging, and he couldn't escape.

Wow!

Finally, a large amount of lake water crossed the long road, and finally rushed into the cave, carrying an incomparable force, even those stalactites, were slapped by the torrent, and they were torn apart!

Like the scene of the end of the world, the heavens and the earth are broken, the seven seas are crossing, and Gu Zhan is like a lonely boat between heaven and earth, which may capsize at any time!

Although it seems to be in a desperate situation, Gu Zhan did not panic, the life of the last days made him hover on the line of life and death every day, and in the long run, although there was little hope of survival of Zhilu Dao, he was still able to keep his head calm. Besides, when Gu Zhan glanced at Huang Feng'er with his residual eyes, the other party also looked as usual, just staring at him without blinking.

"Huang Feng'er must know that there is a road to the outside world, and it is even very likely that this road is in the inheritance cave, because before she accepted the inheritance, at most she was in the early stage of qi refining, how could she enter the spiritual vein like the forbidden land of the sect at that time?"

Gu Zhan sneered secretly, it wasn't that he really didn't think of this consequence before, he was just carried away by greed, at this time, once he came to his senses, he immediately noticed several vitality, Huang Feng'er was one of them! Even if he couldn't go out of the other exit like Huang Feng'er, Gu Zhan had other countermeasures!

Thinking of this, Gu Zhan's mood became calmer, he just kept dodging the stones falling from his head, which was the most important part. This place is thousands of meters deep above the surface, and it must not be buried, otherwise it will be a situation of ten deaths!
