If you want to produce so many low-grade spirit crystals, in addition to the accumulation of years, that is, there are low-grade spirit veins. With so many medium-grade spirit crystals, there needs to be the existence of medium-grade spirit veins. If there is no top-grade spirit crystal, there should be no top-grade spirit vein.

The more Zhao Xuan thought about it, the more excited he became, if he could get a low-grade spiritual vein and a middle-grade spiritual vein, then the cultivation that had not been refined for a long time would definitely be able to go to the next level. This is not the half of the low-grade spiritual veins that Sun Jing gifted, and there are many benefits.

When Zhao Xuan swept all the spirit crystals away, streams of spiritual energy suddenly emerged from the right side of the abyss. The upper magic array moved slightly, rolling the aura and sinking to the bottom of the abyss, which continued.

"The spirit vein must be above!" Zhao Xuan almost couldn't suppress the excitement in his heart, and went all the way up the stone wall on the right.

This discovery also proves the origin and source of the spirit crystal, that is, the transformation of the magic circle and the aura provided on the right side. Zhao Xuan didn't know what it was, but the one on the right side who provided the aura must be the spiritual vein!

When he rose a few meters or so, he smoothly went against the direction of the flow of spiritual energy and broke into the magic circle. As soon as he entered the magic circle, he felt a strong aura rushing towards his face.

A complete low-grade spiritual vein, hundreds of meters high and tens of thousands of meters long, suddenly appeared in front of him. Zhao Xuan could feel the excitement and eagerness from the Qitian Bell. Even in the space of the Soul Suppression Bell, Zhao Xuan could feel the clear spiritual fluctuation.

"This is definitely an unmined spiritual vein! It looks like it should be in the middle of the lower grade spiritual vein, and it is still growing. ”

Mining a spiritual vein is mostly manual. This artificiality does not mean that it should be made manually, but that it should be collected.

For example, a low-grade spirit vein will form a large number of regular finished low-grade spirit crystals around it, and there will be some broken irregular low-grade spirit crystals. What the manual needs to do is to collect it.

Of course, if that lower-grade spiritual vein is complete, basically no one is willing to do it directly against the spiritual vein. It will gather spiritual energy by itself and grow, and there will naturally be spiritual crystals around it. There is also a certain chance that a medium-grade spirit crystal will appear.

If someone is willing to break the complete spiritual vein, it will also form finished products and broken products. If the spiritual veins are broken, they will lose the function of self-growth.

Like this low-grade spiritual vein, it has reached the level of the middle stage. After warm cultivation, the continuous gathering of spiritual energy from nature can also speed up the growth rate. Moreover, this low-grade spiritual vein is not far from the middle-grade spiritual vein, and the growth rate will be faster.

A complete spiritual vein will contain certain Dao rules. So that cultivators can better understand the direction of cultivation and understand some truths that they don't understand. And the spirit crystal formed, this function has decreased a lot, or even disappeared.

Therefore, even if there were more spirit crystals, it was unlikely that they would gather into a single spirit vein. Unless there is an opportunity, there is also the accumulation of years.

These spirit crystals collected by Zhao Xuan were already all the output of the Black Dragon Gate for a hundred years. Every hundred years, the Supreme Elder of the Black Dragon Gate would come down and take all the spirit crystals away. The others do not move at all, waiting for the next harvest.

It is only about ten years before the next Black Dragon Gate collects spirit crystals. This is also the reason why the number of spirit crystals hidden in the attic is slightly less. Every hundred years, the spirit crystals consumed by the Black Dragon Gate are an astronomical amount.

The inventory of the Black Dragon Sect and the wealth possessed by the Supreme Elders are definitely comparable to any of the other three major sects in the Northwest Continent. Even, if it weren't for the fact that the Black Dragon Sect didn't have its own seventh- or eighth-grade alchemy master, its strength would definitely be even more terrifying.

The reason for all this is that the resources at sea are not as scarce as those in the interior, and the other is the spiritual vein.

Although I don't dare to go deep into the sea, I can still go offshore. Therefore, the four major empires and the four major sects have all increased their control and development of the coastal waters. It's just that the four major sects started a little late after all, and they can't catch up with the Black Dragon Gate's waterfront towers.

The spiritual rhyme of the spiritual vein is helpful to the monk's cultivation, and when it reaches a certain level, without the corresponding spiritual energy support, it is difficult to go further.

"Haha...... What a blessing from God! Such a big gift, how can you be polite! If you don't take it, you will suffer it! After Zhao Xuan was dumbfounded for a while, he leaned forward and leaned back.

However, Zhao Xuan didn't do it directly, but cautiously retreated. All the way up, he didn't forget that there was also a medium-grade spirit vein. If the lower-grade spiritual vein is withdrawn, what kind of change will be caused, and the middle-grade spiritual vein will be lost, then it will be a big loss!

When I went up a few hundred meters, I passed through the circle and found the second spiritual vein! The same hundreds of meters high and tens of thousands of meters long are not the middle grade in the guess, but still the lower grade!

Suppress the excitement in your heart and go up again. The third spiritual vein was discovered, and it was still inferior. It's just that this third lower-grade spiritual vein is already close to a kilometer in height and longer in length.

After that, there is the fourth lower grade spirit vein, which is similar to the third spirit vein.

Then upward, followed by the fifth, this time it seems to be a medium-grade spiritual vein. The height reaches about 1,500 meters, and the length reaches nearly 50,000 meters. Waves of thick white spiritual mist were emitted, drifting down the abyss of the formation.

After calming down, Zhao Xuan went up again. After that, there is the sixth lower grade spirit vein, the seventh lower grade spirit vein, the eighth lower grade spirit vein, and the ninth lower grade spirit vein!

That is to say, more than 10,000 meters on the right side of the mountain, where the formation is shrouded, there are nine spiritual veins up and down! The upper four and the lower four are the lower grade spirit veins, and the fifth in the middle is the middle grade spirit veins!

"! It's so rich! "As far as Zhao Xuan knows, a sect at the level of the Zhudan Realm generally only occupies a place with abundant spiritual energy. Only those top-notch Zhudan Realm sects will have low-grade spiritual veins, and some are still incomplete.

A Black Dragon Gate can have so many spiritual veins, and there are medium-grade spiritual veins among them, it is really rich! What's more, if it was said that there was no spiritual vein inside the mountain gate outside, Zhao Xuan would not believe it.

"It seems that I underestimated these sects before!" The Black Dragon Gate is hidden, and it's strange that the other sects don't hide it.

You know, the spirit crystal is not like the gold coins and purple coins in the secular world that can be circulated forever, but the spirit crystal will be consumed. If it has been consumed without replenishment, how can it be used as the circulating currency of the cultivation world?

The more he thought about it, the more he compared, the more aggrieved Zhao Xuan felt.

The dignified Qitian Sect, such a bull-breaking sect, even if it has declined, I haven't seen anything good. Now, except for the Qitian Bell and a sect array, he has not gotten anything.

It's the Qitian Sword and the Xuanyuan Divine Furnace, those exercises are still given by the snow. The space of the Soul Bell was still obtained from the Nebula Gate, and it took a lot of effort to repair it.

"I'm the sect master, hey, it's really ......" Although I feel uncomfortable, it's not my own sect. Don't say that you haven't been back to see it for so many years since you came out! It's time to go back, and there are some doubts that haven't been solved yet!

No matter what his thoughts are, what he has to do now is how to collect these spiritual veins without alarming the Black Dragon Gate.

Generally speaking, in order to collect a spirit vein, you need to have a corresponding storage ring. First of all, the ring space should be sufficient, secondly, the ring grade should be high enough, and secondly, it should be enough to cultivate.

How to place the ring if there is not enough space? How can a kennel fit an elephant?

If the grade of the ring is not enough, the spiritual pressure of the spiritual vein will destroy the ring, and it will also damage the spirituality of the spiritual vein. For the lower grade spirit vein, you need a ring above the middle grade spirit weapon with enough space to collect it. Medium-grade spiritual veins need high-grade spiritual weapon rings. The grade of Shennong's ring is enough, but the space is not enough.

If you don't cultivate enough, you can't even move the spiritual vein, so how can you collect it? Generally speaking, this also requires the help of certain formations. Even if the cultivation is barely enough, the movement is not small. Unless you cultivate to the sky, you can forcibly compress the spiritual vein into a small object, and it is no problem to hold it in your hand.

Therefore, this time Zhao Xuan will be in trouble.

The problem of placing space is easy to solve, and the interior of the soul bell is sufficient. Not to mention nine spiritual veins, even nine hundred and nine thousand spiritual veins, no problem. There is no need to worry about the level of space. No matter how broken the soul bell, it is also a half-immortal weapon, and placing the spirit vein can also speed up the recovery.

Now the main thing is that the cultivation is not enough, which is a hard injury. I don't know how to arrange the traction formation, which is also a shortcoming.

Under normal circumstances, with the initial cultivation of the Zhudan Realm, it is enough to collect the lower grade spiritual veins. What's more, Zhao Xuan's strength is now not inferior to the peak of the Zhudan Realm, and it is no problem to receive a medium-grade spiritual vein, even a high-grade spiritual vein can give it a try.

However, these nine spiritual veins are all locked by the formation! It's really difficult not to make a big move, not to cause an attack from above, and not to attract the attention of the Black Dragon Gate.

This kind of entanglement of entering Baoshan and returning empty-handed is really anxious!

"This sect master still doesn't believe it, this can still be difficult to defeat me!" Zhao Xuan was ruthless, and he controlled the Qitian Bell and jumped out again. Begin to walk around the mountain on the right to determine the extent of those imprisoning circles.

It's not afraid to cause a big stir and attract the attention of the Black Dragon Gate, the key is to stop it after only collecting one spiritual vein, that's the loss! Therefore, what I am thinking about now is how to collect all the nine spiritual veins at one time.

As for the impact caused by the collection, it is not taken into account. Compared to the temptation of the nine spiritual veins, the others really don't matter.

After a round of observation, what made Zhao Xuan more satisfied was that the nine formations where the spirit vein space was placed only extended to the right side for two or three hundred meters at most. Three or four hundred meters below, there are underground rock formations with many cavities.

Starting from above, along the edge of the circle, one side condensed the Qilin Fire into a fire knife and began to cut the rocks, and the other side controlled the Qitian Bell to cut at the same time. Zhao Xuan's idea was also very simple, directly cut off the mountain on the right side, and opened a crack to let the two separate.

The mountain that you want to intercept is 10,000 meters up and down, 50,000 or 60,000 meters long, and several thousand meters wide. Fortunately, the left side is the abyss cliff, and the upper side has also been separated, so that only four sides of the cut need to be completed.

This is also a big project! With the support of Zhao Xuan's Yuan Force and spiritual power, even if he maintains his peak state, he will not be able to think about it for more than a dozen hours. In these dozen hours, most of the daytime has to be thrown away, that is, it will take three nights or more to complete.

If in the middle of this, the Black Dragon Gate finds an abnormality, then it will basically be wasted.

However, Zhao Xuan did not hesitate at all! The harvest of one medium-grade spiritual vein and the harvest of nine spiritual veins do not need to be chosen at all, at most they take a little risk.
