Judging from the experience of the four six-winged "Dark Spirit Bats", these three corridors should be the core of the formation in the forbidden area.
They thought of the strong man from the same clan who had frantically broken the restrictions of the cave, and for a moment they hesitated whether to really break the restrictions and go in to check the situation.
But this hesitation did not last long. Compared with the lives of their fellow tribesmen, they had no choice.
Therefore, it was decided to use a six-winged "Dark Spirit Bat" to break the barrier, so that if any problems occurred, the entire army would not be wiped out.
The six-winged "Dark Spirit Bat" that broke the ban on the corridor was Meng Zhiyuan's master, the strongest person here.
Finally, after spending eight months, he really broke the ban on a corridor, and nothing happened.
After successfully entering, they finally discovered the top-grade spirit stones piled up like hills in the core of the formation.
The four-winged "Dark Spirit Bats" were so frightened by the presence of so many top-grade spirit stones that they could not make any other sound except for gasping for air.
The number of these top-grade spirit stones is something they have never seen in their entire lives. If their clan can possess these top-grade spirit stones, they believe they can definitely create a powerful god-transforming warrior.
What disappointed them was that most of these top-grade spirit stones had become dull and lifeless, as if covered with a layer of death.
Only about 30% of the top-grade spirit stones were still shining, but it was obvious that most of the spiritual energy in them had been lost.
However, even within these 30% or so top-grade spirit stones, a lot of spiritual energy had disappeared. But for cultivators, the rich spiritual energy still gave rise to endless greed.
If these four strong men were to practice with this spiritual energy, they might have the possibility of making a breakthrough.
With their level of cultivation, even in the outside world, it would be extremely difficult to make any further progress. But with the help of top-grade spirit stones, the situation is completely different.
In their impression, no matter how powerful a sect is, they would not be so extravagant as to use top-grade spirit stones for cultivation.
Fortunately, the four six-winged "Dark Spirit Bats" managed to retain their remaining sanity at the last moment. They knew the importance of these top-grade spirit stones.
There are three corridors at the core of the formation, which continuously transport pure spiritual energy in three directions, thus maintaining the normal operation of the forbidden area.
This is the key to their clan's immortality.
A problem arose at this time. Although they found the core of the formation, they also immediately saw the cause of the death of their tribesmen.
If you want to solve this problem, you have to take out a large amount of top-grade spirit stones to restore the forbidden area.
But where do the top-grade spirit stones come from? First of all, the cave here is too hidden, and not many cultivators come here.
They also couldn't go out to steal spirit stones because they couldn't leave the area within fifty miles.
Secondly, they didn't have many spirit stones left, which they needed to use to prolong their lives at critical moments.
There are only eight high-level spirit stones, more than thirty medium-level spirit stones, and thousands of low-level spirit stones.
And the most important thing is that this formation uses top-grade spirit stones.
Even if they could rob them, it was impossible for so many top-grade spirit stones to appear, except for a few pieces occasionally carried by some Nascent Soul cultivators and above.
So the four six-winged "Dark Spirit Bats" began to ponder, and finally they thought whether they could slightly modify the core of the formation, or use other means to assist the core of the formation to enhance its power.
The person who originally set up this formation was many times more powerful than them. Even if there were four Nascent Soul-level powerhouses here, it would be very difficult to transform it.
Moreover, they did not dare to move rashly. After thinking for a long time, they decided to keep the original formation structure unchanged.
Instead, he added a small formation next to the core of the formation, which could assist the power he had acquired to the three corridors.
In this way, the consumption rate of the remaining 30% of top-grade spirit stones can be greatly reduced, extending the operation time of the forbidden land formation.
Although some tribesmen will still die, they will not die in large numbers.
With their hard work, this formation was finally completed after a total of seventy-three years.
The most difficult thing here is not to arrange a small formation, but how to completely integrate the two forces without affecting the original operation of the large formation.
Every step must be deduced repeatedly countless times, because they only have one chance. If they make a wrong step, the entire forbidden area may be destroyed in an instant.
After the formation is completed, not only can ordinary spirit stones be used to assist the output of spiritual energy, but the cultivator's essence, blood, magic core, and golden elixir can also be converted into spiritual energy output.
However, the power converted from the magic core and the blood essence of magic beasts is too violent, so it cannot output power as long as ordinary spirit stones and the golden elixir of cultivators.
There are very few monks in this sea area, but many sea monsters often appear nearby. As long as they can capture these monsters, they can solve their urgent problems.
Whether it is the essence, blood, magic core, or golden elixir of magical beasts or cultivators, they are the essence of the cultivator's body. This is also the best thing they can think of to replace spirit stones.
If you can kill a Nascent Soul cultivator, one Nascent Soul may be worth two or three top-grade spirit stones.
As a result, various levels of magical beasts in the surrounding seas suffered a devastating disaster. There was even a fourth-level sea magical beast in this sea area.
So the "Dark Spirit Demon Bat" began to go out continuously and show up deliberately. From the lowest level magic beast to the mid-level sea magic beast, they were all led into the forbidden area one by one in the end.
Four six-winged "Dark Spirit Bats" attacked at the same time, and even the fourth-order sea monster was led into the forbidden area and was eventually killed in it.
Afterwards, although some members of the "Dark Spirit Bats" in the forbidden land continued to die, their numbers were no longer increasing rapidly year by year.
Year after year, they hunted the monsters in the surrounding seas, and occasionally monks passing by would suffer the same fate. The "Dark Spirit Demon Bat" clan waited in agony for the return of "Venerable Duanmu".
The magical beasts in the surrounding waters also disappeared one by one silently, entire groups were wiped out, and their numbers decreased sharply.
This is certainly not good news for the "Dark Spirit Demon Bat" clan.
Without the support of strength, the remaining top-grade spirit stones will be consumed faster and faster, which makes the four six-winged "Dark Spirit Bats" more and more anxious.
And one day, outside the cave in the deep sea, a young man in white came. He stood on the mountain under the sea and looked at the mountain where the "Dark Spirit Demon Bat" clan was hidden.
Then, he flew to the mountain wall where the female cultivator named Yang broke the ban.
The arrival of the young man in white made the four six-winged "Dark Spirit Bats" particularly excited, because the faint aura fluctuations emanating from this man were actually from the Nascent Soul stage.
They guessed that it was the low-level "Dark Spirit Bats" sent out from the periphery that deliberately emitted auras that attracted the other party's attention, causing them to rush over.
After all, at this time in this deep sea area, except for ordinary sea creatures, even the first-level monsters have been basically killed.
The formation is operating in the forbidden area every day. Since the middle and high-level monsters are gone, the low-level monsters are replenished in number.
Even if ten low-level monsters could condense a tiny drop of blood essence, that would be good.
In this way, if a cultivator occasionally enters this deep sea and suddenly senses the breath of some "dark spirit bats" when there is nothing around, it will immediately appear so abrupt like a bright light in the dark night.
Then, four six-winged "Dark Spirit Bats" led by Master Meng Zhiyuan immediately surrounded them from the dark, but just as they got a little closer, the young man in white snorted coldly.
"You are such a fool!"
Master Meng Zhiyuan and the other three knew that they had been sensed by the other party, so they did not hesitate any longer and immediately pounced on them with a hideous grin.
As for how they were discovered by the other party, for cultivators at their level, the connection between life and death is inexplicable. This is related to the skills they have practiced and the battles they have experienced.
What's more, it is not uncommon for a cultivator in the Nascent Soul stage to have a super-powerful warning magic weapon.
Especially among the four people including Master Meng Zhiyuan, there are already two people at the peak of the fourth level, that is, great cultivators in the late Nascent Soul stage.
This was also one of the main reasons why we dared to surround and kill the fourth-level monster in the sea.
In addition, the "Dark Spirit Demon Bat" clan has been imprisoned here. No matter how deep their cultivation is, it is difficult for them to remain calm. Instead, they are plagued by viciousness and cruelty.
Therefore, under such circumstances, even if the other party has a magical weapon that defies the heavens, they will rush up without hesitation, capture his Nascent Soul, and refine his essence and blood.
However, as soon as the ferocious expressions on the faces of the four six-winged "Dark Spirit Bats" appeared, they froze on their faces the next moment.
Because they found that their bodies could no longer move at all in just a moment.
"What level are you!!!"
Following the sharp screams of several six-winged "Dark Spirit Demon Bats", four powerful beings that were enough to shake the world and roam the world exploded into blood mist in an instant, and not even a Nascent Soul escaped.
By the time Master Meng Zhiyuan and the other three discovered something was wrong, it was already too late.
The reason why they shouted that was because even if the other party was a powerful person in the late stage of the Spirit Transformation Realm, it would be impossible for him to imprison them so easily.
You should know that there are great cultivators in the late Nascent Soul stage among them. At this point, they already have some control over the laws of heaven and earth.
That is a power beyond this world. In a situation where life and death are at stake, it is possible to resist for half a breath to a breath.
However, after discovering them, the young man in white didn't even move, he just glanced at them coldly.
With just one glance, the strength in their bodies disappeared completely in an instant, and they no longer had the slightest desire to resist.
In a flash, they had already determined that this person was even more terrifying and powerful than the "Venerable Duanmu" of that year, and they didn't know how many times more powerful he was.
It was obvious that the other party had concealed his cultivation level before, but before they could beg for mercy, an unrivaled force instantly destroyed everything they had.
The young man in white snorted coldly, then he waved his hand and grabbed the several balls of blood mist that had exploded.
Then, as if kneading a real object, he kneaded the blood mist into a dark ball of light and threw it into the storage space.
"You ant, you actually wanted to launch a sneak attack on my family. You deserve to die!"
Afterwards, the young man in white actually ignored the restrictions here, took a step forward, and the next moment he appeared in front of the three sub-caves inside.
Looking at the three sub-caves, the man in white took a few quick glances and immediately walked towards the cave that was considered the most mysterious by the "Dark Spirit Bat".
Then, his figure quietly merged into the gate of the cave like a drop of water.
All this fell into the eyes of those terrified "Dark Spirit Bats" in the dark. This man was too powerful.
Not to mention that the four strongest men in the tribe could not survive a single breath in front of him, even the cave that they regarded as extremely mysterious was walked into by him in one step as if he was stepping into his own home.
Just when they were wondering what to do next.
Just a breath and a half later, the figure of the young man in white suddenly appeared again in the square outside the sub-dong residence.
