The advantage of this type of circle is that the cost of the spirit stones used to arrange the circle is very low, which is one percent or less of the cost of the spirit stones of the ordinary magic circle.

So, that's why these circles have survived thousands or tens of thousands of years and are still intact.

Of course, there are two sides to everything, and there is an advantage and a disadvantage.

The downside is that the small circle that controls the entire circle is very simple.

If you can find it, just use your divine sense to probe in and see how it works.

Disarm the circle from the inside so that the entire Cave Circle can be closed from the inside.

After that, the cave was also able to enter and exit freely.

After this discovery, Lin Yang was also quite excited, and saw Lin Yang standing in front of the stone gate of a cave mansion, looking at the gate of the cave mansion.

After the time of a stick of incense, Lin Yang didn't see any movement, his hands pressed on the gate of the cave mansion, and pushed hard.

The door of the cave was opened, and then Lin Yang raised his legs and entered the cave and disappeared.

Such a strange scene, if the Wei family brothers and the Yan family saw it, their jaws would definitely drop.

They would never have thought that Lin Yang would enter the cave mansion in this way.

At this moment, the brothers of the Wei family and the people of the Yan family are casting spells to destroy the remaining cave magic circles with all their might, striving to find more treasures.

However, it is not easy to encounter magic weapon-level treasures, and only by opening the caves of those monks in the Dan stage can you have a chance to obtain them.

In the space of seven days, Lin Yang had already searched hundreds of cave mansions, and in addition to finding the earth-level magic weapons, there were also some unnamed pills.

However, the medicinal power of many pills has dissipated, and the few spirit stones found are pitiful, only more than a ten.

This also made Lin Yang understand that the reason why the cave here arranged the kind of magic circle that saved spirit stones was that the spirit stones here were relatively scarce, and they should not be able to be replenished from the outside world.

After inspecting hundreds of caves, Lin Yang also found that the owners of these caves never came back after a certain outing.

The monks had a habit of keeping their treasures in storage bags.

Therefore, although the number of caves searched is relatively large, most of the monks' caves are empty.

Most of the monks' caves have not found any valuable treasures, and there are also no monks' bones.

From this, it can be judged that these monks have not returned since leaving the cave.

However, the bones of some monks and some storage bags have also been found in several caves.

Lin Yang found a problem by examining these bones, which were more or less scarred.

Some of the bones were shattered, and some of the bones had turned black in color, apparently due to poisoning.

In this way, it is not difficult to see that the owner of these bones should have returned to the cave to heal after being injured in the mission, and then fell in the cave.

Some jade slips were also found in these caves, and after viewing them.

Lin Yang also figured out some secrets here, it turned out that tens of thousands of years ago this was a sect of immortal cultivation called Jiuxuanmen.

They were here to enter another continent, which is not mentioned in the Jade Slip.

The other jade slips recorded that the Heavenly Migration Continent suddenly descended on Mo Yi and many foreign demon beasts.

These demon beasts are powerful and can sweep through the entire Terran cultivators of the Heavenly Shift Continent.

The Terran monks of the Heavenly Migration Continent were almost wiped out, and they fled here just to avoid the pursuit of those demon beasts and leave this continent.

Through the descriptions in these jade slips, Lin Yang also guessed some things back then.

First of all, the Jade Slip mentions the Tianyi Continent, is it the same continent as our current Tianyi Continent?

Lin Yang thinks that the characters in other places can be wrong, but the name of the continent will never be wrong, it should be our current Tianyi Continent.

So long ago, why were those ancient monks called this continent the Heavenly Migration Continent?

Lin Yang couldn't figure it out, this was also the first time Lin Yang had heard the name Tianyi Continent.

Through the descriptions in these jade slips, there was a foreign invasion of this continent tens of thousands of years ago.

It was probably that the Heavenly Migration Continent had been attacked by some powerful demon beasts, and these demon beasts came from another continent.

The monks of the Heavenly Migration Continent were not the opponents of these foreign demon beasts at all, so at that time, there was a group of monks from this sect called the Nine Xuanmen Immortal Cultivation Sect who hid in this underground palace.

I want to escape from here to a safe place, but something must be wrong.

These people of the Nine Xuanmen had to fight, and the battle lasted for a long time, possibly for several generations.

In the end, it is unclear whether someone managed to be teleported to another continent, or whether all of them fell here.

Through these days of treasure hunting, Lin Yang also understood why Yan Qing was not interested in treasure hunting.

The reason is that most of the monks' caves are empty, and there are no treasures at all.

Lin Yang has also made discoveries through these days of exploration.

At this moment, he did not open each closed cave one by one, but by looking at the scale of the cave and the difficulty of the magic circle.

Choose those caves that are large in scale and more complex in the circle to enter.

In this way, it not only saved a lot of time, but also gave Lin Yang the opportunity to harvest some valuable treasures.

Sure enough, when he entered a cave with an inconspicuous appearance, the area inside was several times the size of an ordinary cave, and a medicine garden was actually opened up behind this cave.

What made Lin Yang excited was that there was also a spirit grass growing in the medicine garden, this kind of spirit grass Lin Yang had never seen before.

The moment Lin Yang opened the stone door of the medicine garden, a strong medicinal fragrance rushed to his face, and after smelling it, his spirit was shocked.

This medicine garden was only more than ten zhang in circumference, and in the middle of the medicine garden, a spirit grass more than three feet tall was still alive.

The white branches of this spirit grass grow in the shape of a bamboo, and several branches grow from the main trunk, which are covered with blue leaves.

The leaves are half the size of a palm, very heavy, and are dotted with some golden spots.

This medicinal fragrance emanates from these leaves, specifically from these golden spots.

After Lin Yang instructed Xiao Xi to move this spirit grass into his body, Xiao Xi showed an excited expression and smiled at Lin Yang.

"Master, this spirit grass has been burning for 50,000 years, and I have never seen such a high age spirit grass.

It's a pity that the aura here is insufficient, if the aura is sufficient, this spirit grass may enter the condensation stage or even the transformation stage. ”

Lin Yang also smiled slightly after hearing this, and said, "After searching so many caves, I finally have some gains.

However, this spirit grass is full of fragrance, could it be that tens of thousands of years of spirit grass have such a strong aroma?"

Xiao Xi shook his head and said: "Of course not, the aroma of this spirit grass has a deworming effect according to my judgment, and I can't say the specifics, anyway, it has a restraining effect on some poisonous insects." ”

After Lin Yang heard this, he pondered in his heart, and he also thought of some things.

Some of the leaves underneath this herb have been picked.

Although the time is long, you can also see the traces after being picked, could it be that this herb is related to the transformation of the spirit powder that the Wei brothers said?

Or is there a poisonous insect here that needs the aroma of this spirit grass to drive it away?

Whatever the reason, Lin Yang first collected a bottle of medicinal incense and put it in a storage bag.

I vaguely felt that this bottle of medicinal incense would definitely come in handy here, and after leaving this cave, I continued to check other caves, but I didn't get much.

At this time, there was a roaring sound, which was the sound coming from the place of the magic circle arranged by Yan Qing.

Lin Yang fled towards the place where Yan Qing was, and at this moment, several monks of the Yan family and the two brothers of the Wei family all felt this place one after another.

I saw that Yan Qing was holding an array disk in his hand, and the magic circle was condensing golden thunder one after another, blasting towards the rockery on the pool.

Under the bombardment of the golden thunder, the rockery flashed with golden light, and there was no sign of damage.

At this time, Yan Qing said loudly to everyone: "Fellow Daoists, attack that rockery with all your might, there is a magic circle on it at this moment, and only by breaking this magic circle can you find that passage." ”

As soon as the words fell, the Wei family brothers and the Yan family all attacked the rockery with their magic weapons, and Lin Yang also had an extra big knife in his hand to bombard the rockery.

Yan Qing said loudly while manipulating the magic circle: "This is likely to be an ancient battlefield, or some powerful demon beasts have been sealed.

It may also be the healing place of some high-ranking monks, but this seal has been going through tens of thousands of years.

At this moment, the power of the seal inside is almost exhausted, and I believe that it will not be long before the power above it will be exhausted.

Whether it was a big chance or a danger under the magic circle, Yan didn't know, and everything was clear after opening the stone door. ”

Lin Yang still agreed with Yan Qing's words when he heard this, no matter how he looked at it here, it was not like what the Wei brothers said was where the cave mansion of a high-level monk was located.

Lin Yang analyzed according to the records in the jade slips he obtained:

This is most likely an ancient battlefield as Yan Qing said, and secondly, it is likely to be the place where some demon beasts were sealed.

When those monks of the Nine Xuanmen left the cave, they must have gone out through this stone gate to perform some tasks.

Most of them did not come back, which is enough to show that there is a dangerous place behind the stone gate.

I don't know how many years have passed, and in the end, the resources of the Nine Xuanmen have almost dried up.

The monks of the sect were also killed and wounded, and in order to prevent enemies or demon beasts from breaking into this place, a certain powerful person of the Nine Xuanmen sealed this place.

has been sleeping for tens of thousands of years, who sealed this place?
