After thinking about it for a while, Li Xuangang felt that it was impossible for those absorbed spiritual qi to disappear for no reason, so he found a clearing in the boundary source space, and then arranged a spirit gathering magic circle on it.

Finally, he put some of the demon beast corpses he had collected in the Spirit Gathering Circle. Three days later, when Li Xuangang opened the Spirit Gathering Array again, the corpses of the demon beasts inside had disappeared.

And a spiritual aura that was even richer than other places overflowed from the Spirit Gathering Array arranged by Li Xuangang.

A rich aura brushed Li Xuangang's cheeks, and he frowned tightly and began to think about the cause and effect relationship.

In the end, Li Xuangang came to a conclusion that he had no way to verify for the time being.

He believed that the aura absorbed by the Boundary Source Space had not disappeared, but had been dispersed throughout the Boundary Source Space.

It's just that the amount of aura he replenished for the Boundary Source Space was too scarce, so after being diluted by the entire Boundary Source Space, he didn't feel the change in the concentration of the aura.

Li Xuangang had measured the entire Boundary Source Space, and in his measurements, the Boundary Source Space was thousands of acres in area, if he really wanted his conjecture to be confirmed, then he had to provide an incredibly large amount of aura, and then he could make the aura concentration of the entire Boundary Source Space rise to the level that he could perceive.

Now in Li Xuangang's perception, the concentration of spiritual energy in the entire realm source space is equivalent to a first-order low-grade spiritual vein, which can supply himself to open up twenty acres of spiritual land.

Li Xuangang thought silently in his heart for a while, and found that he could improve the spiritual vein level of the boundary source space by continuously replenishing items containing spiritual energy to the boundary source space, such as the corpses of demon beasts abandoned by others.

But he immediately realized that this was an extremely difficult task, because it was equivalent to letting him cultivate a spiritual vein alone, even if he could put a lot of useless items in it and recycle it, the spiritual vein in the boundary source space was destined to not be promoted quickly.

According to Li Xuangang's estimate, it was impossible for the aura growth rate in the Boundary Source Space to keep up with his cultivation speed, so he couldn't cultivate in it.

However, Li Xuangang still decided to consciously increase the concentration of aura in the realm source space in the future, because although it could not be provided for him to cultivate, it could create a growth environment that was more suitable for high-level spirit plants.

With the improvement of Li Xuangang's cultivation, then he must plant some higher-level spirit plants, and these high-level spirit plants generally have a relatively high demand for the concentration of spiritual energy in the growth environment.

After figuring out this characteristic of the boundary source space, Li Xuangang also made a plan for this feature. The only thing he had to consider now was why he used spirit stones to give birth to spirit plants, which would span the length of their lives in a short period of time.

Li Xuangang has never received an answer to this question, and he has tried many methods, but he has not sought a reasonable explanation. This was beyond his comprehension.

However, when Li Xuangang went out of the Boundary Source Space, he still firmly believed that there must be a certain substance in the Boundary Source Space that he didn't know, and this substance could help the Spirit Plant quickly complete the leap of the life stage when a pure Spiritual Qi aggregate like a Spirit Stone provided the aura.

But he doesn't know what this substance is, how much is it, and is it going to be consumed?

However, this question is meaningless to Li Xuangang at this stage, because he will not use spirit stones to give birth to spirit plants at all. The same number of spirit stones was enough for him to go to the Fang Market to buy the same spirit plant.

Li Xuangang himself understood this, and he wondered if this substance had other functions that he didn't know about?

......

Back in his cave, Li Xuangang put away the Boundary Source Bead, and then removed the Sancai Spirit Array.

He figured out another property of the Boundary Source Space.

But after thinking about it, he reluctantly found that this was equivalent to letting him cultivate a movable spiritual vein by himself, knowing that it had taken him hundreds of years for his entire family to raise the spiritual vein of Taiqiu Mountain to the third order.

This shows how many resources it takes to cultivate a spiritual vein.

Li Xuangang walked outside the cave mansion while thinking that it was obviously not feasible for him to use spirit stones to increase the concentration of spiritual energy in the boundary source space, and he didn't have so many spirit stones. And it is still not possible to use the resources you need to increase the concentration of spiritual energy, because this will inevitably delay your cultivation speed.

In the end, when he walked to Wujiangfang City, Li Xuangang still felt that it was most cost-effective to go to the Hengduan Mountain Range to pick up the corpses of demon beasts that other monks couldn't take away.

However, Li Xuangang also figured out this matter, and there was no need for him to deliberately increase the concentration of spiritual energy in the realm source space, because no matter what, it was impossible to raise the spiritual veins in it to a high level by himself alone, so he was destined to be unable to cultivate in it.

And the only purpose of cultivating the aura concentration in oneself is to provide a good growth environment for the high-level spiritual plants that may be planted in the future.

......

In order to make some necessary preparations for his next plan, Li Xuangang felt the need to buy himself a few higher-level storage bags so that he could hold more demon beast corpses.

So after settling the remuneration he had received for refining the Chunlu Pill for the Ghoul Sect during this time, he raised his feet and entered the largest grocery store in Wujiangfang City, where he could buy the storage bag he wanted.

After spending nearly five hundred spirit stones, Li Xuangang left the grocery store with three storage bags with more storage space.

Standing on the streets of Wujiangfang City, Li Xuangang thought for a while, and then he decided to go to the family's grocery store and refining pavilion to ask if he had received Xuanyin Sand during this time.

If he could get Xuanyin Sand, then Li Xuangang planned to use the remaining spirit stones to refine an armor for his own corpse.

After walking for a while, Li Xuangang walked to the family's grocery store, but he didn't get a good news, and the clansmen in the grocery store told him that he hadn't received Xuanyin Sha for a year.

After thanking the other party, Li Xuangang left the family's grocery store and walked towards the Refining Pavilion.

But half a day later, Li Xuangang got the same answer from the Refining Pavilion.

In the end, Li Xuangang returned to his cave with a little disappointment.

The next six months were quite dull for Li Xuangang.

He had done these few things in the past half a year: serving the spirit plant in the boundary source space, going to the Ghoul Sect Alchemy Pavilion to refine the Spring Dew Pill, and cultivating to consolidate his eighth-layer realm of qi refining. There is also the constant strengthening of his mental connection with the Eight Spider Blue Light Sword.

One day half a year later, Li Xuangang had just finished his cultivation and then summoned his refining corpse out.

Previously, after he added enough demon beast essence blood to the Nayin gourd, he had never summoned his own refining corpse.

Now he summoned the refining corpse that had been cultivating in the Nayin gourd for two years, and found that his refining corpse had reached the edge of breaking through the sixth layer of qi refining, and he believed that after a period of demon beast essence blood cultivation, he should be able to successfully break through to the sixth layer of qi refining.

After checking the cultivation of the corpse, Li Xuangang made a big move and put it into the Yin gourd on his waist.

But just as he was about to enter the Boundary Source Space, someone outside the cave asked to see him.

Li Xuangang opened the ban of the cave mansion, and then found that it was the tenth brother Li Xuankun who came to find him.

"Ninth brother, Seventh Uncle summoned us to the Refining Pavilion tonight!"

This was the first thing Li Xuangang heard Li Xuankun say.

On the way to the family refining pavilion, Li Xuangang asked Li Xuankun next to him and asked:

"Xuankun, do you know what the Seventh Uncle summoned us for this time?"

Li Xuankun turned his head to look at the ninth brother Li Xuangang as he walked, and said:

"Brother Jiu, you have been in retreat for the past two years, so Uncle Seventh didn't inform you, in fact, two years ago, Uncle Seventh gave a task to all the clansmen in Wujiangfang City. ”

Hearing this, Li Xuangang reacted that two years ago was the time for him to decide to retreat and cultivate.

Then he asked, puzzled:

"What kind of task?"

Li Xuankun replied:

"Uncle Seventh asked us to look for the traces of a group of elephant tortoises in the Hengduan Mountains, we have been looking for two years, and this time we were summoned to go, I think someone should have found his traces. ”

Hearing this, Li Xuangang was stunned.

It is no wonder that two years ago, at the auction hosted by the Ghoul Sect, the Seventh Uncle Li Changzhi would be willing to buy the tampering secret technique of the elephant tortoise beast for the price of two thousand five hundred spirit stones.

At nightfall, the Li family of Taiqiu Mountain was in the family refining pavilion in Wujiangfang City.

A group of Li clansmen dressed in black costumes stood solemnly, waiting for the appearance of the family elder Li Changzhi.

In fact, except for a small number of clansmen present who didn't know why they came, everyone else probably guessed the reason why Uncle Seven summoned everyone here.

After waiting for a while, a cave in the backyard of the family refining pavilion was opened, and three figures came out of it, and the first to come out was Li Xuangang's seventh uncle Li Changzhi and sixth uncle Li Qingshu, the one who walked behind made Li Xuangang a little surprised, it turned out to be the third uncle Li Qinghuan who had not been seen for a long time.

Li Xuangang and his second brother Li Xuantian stood together, and the latter quietly touched Li Xuangang before saying:

"I haven't seen you for two years, and Xuan Gang has already refined qi at the eighth level. ”

Li Xuangang also lowered his voice and replied:

"Lucky breakthrough. ”

Li Xuantian was about to say something more, but Li Changzhi interrupted him with two coughs, which also made the whole scene fall into silence.

Li Changzhi looked around at the Li clan people present, and then spoke:

"I believe that many of you already know the reason, but I still have to say a word. ”

Li Qingshu also returned to the bottom to stand still, leaving the position to the seventh uncle Li Changzhi and the third brother Li Qinghuan.

Li Changzhi went on to say:

"Two years ago, I sent a task to find the Elephant Tortoise Beast, after two years of searching, we finally determined the location of this group of Elephant Tortoise Beasts, this time I summoned you for this group of Elephant Tortoise Beasts, this operation is led by me and Qing Huan. In order to hide people's eyes, you will enter the Hengduan Mountains in groups of three, and I will send you a map later, and you will gather with the red dots marked on the map after you enter the Hengduan Mountains. ”

After Li Changzhi finished speaking, Li Qinghuan also emphasized the importance of this operation to the many clansmen, and determined the list of groups of three, as well as the time and place for each group to enter the Hengduan Mountains.

Under the assignment of the third uncle, Li Qinghuan, Li Xuangang was assigned to a group because he was close to Li Xuantian and Li Xuankun.

There were a total of thirty Li clan members who participated in this operation, except for Li Changzhi and Li Qinghuan who opened the foundation building period, there were ten groups in total, and most of them were cultivators in the late stage of qi refining.

Li Xuantian glanced at the map issued by the third uncle, Li Qinghuan, a few times, and then said to Li Xuangang and Li Xuankun:

"According to the arrangement of the seventh uncle and the third uncle, the three of us will set off tomorrow morning and enter the Hengduan Mountains from the northwest direction of Wujiangfang City. ”

Now that the time and place of departure have been determined, the Li clan people who gathered in the family refining pavilion bid farewell to Li Changzhi and Li Qinghuan one after another, and then scattered in various parts of Wujiangfang City, preparing for the family collective mission to enter the Hengduan Mountain Range this time.

And Li Xuangang, Li Xuantian, and Li Xuankun also left the Refining Pavilion and walked towards the northwest city wall of Wujiangfang City.

After these Li clansmen walked to the predetermined location, they silently took off the family's standard Xuan clothes, and then changed into other clothes that had been prepared.
