After getting the information left by the Xuangui Daoist, this secret realm has no secrets for Shi Yuan, but he doesn't have much time to slowly accept the test of the Xuangui Daoist, and after walking back and forth around the hall, he came to the crystal wall behind the crystal ball.

The crystal clear crystal wall seems to have no gaps, and when the divine mind scans it, it is directly absorbed and isolated, and it is difficult to penetrate the past to see the scene inside.

Seeing this, Ishihara smiled slightly, and unhurriedly played a series of tricks, and a seven-colored brilliance was immediately projected onto the crystal wall, and the color changed for a while and reflected a purple brilliance, but it was still mixed with dense red dots.

This shows that the strength of this crystal wall has exceeded the strength of the shield of the Jindan Great Perfection Monk, and if it attacks it, it will directly activate the attack prohibition counterattack in the Crystal Palace, which is enough to trap the Jindan Great Perfection Monk.

However, Ishihara was not surprised to see this, the spell he just used was called the Seven Spirits Forbidden Method, which was developed by him based on years of forbidden research, a spell that specifically explored the strength, type, and efficacy of the prohibition, although it was not as clear as the Heavenly and Human Brand and Mud Pill God, but it was better than being able to teach others to use, and it was even more wonderful to cooperate with Ishihara's distraction.

Therefore, Ishihara couldn't help but nod his head with satisfaction as he looked at the crystal wall that had been infected purple, he had just discovered that the material of this crystal palace was not any material he knew, but more like it was shaped by some kind of water method directly condensing water into crystals.

Therefore, it is not this material that can absorb divine thoughts, nor is the strong defense it shows not its own characteristics, but the ability brought by the prohibition contained in it.

And this crystal, I am afraid that it is a kind of mana material specially condensed by the Xuangui Dao people in order to bear the prohibition, if you take off a part of it to cut off the connection with the Crystal Palace, it will directly turn into ordinary clear water and disappear with aura.

Otherwise, this kind of spiritual material with such good performance and such a large number of spiritual materials would be in no way inferior to earth-level heavenly materials and earth treasures, how could it be so wasteful to build a palace.

Reach the crystal wall again, and the crystal wall can't stop it. Through the purple light infected, Ishihara's divine thoughts directly penetrated into the forbidden interior, and then suddenly spread his vision to the entire crystal palace, and a 3D phantom-like model was imprinted into Ishihara's heart.

It's really exquisitely structured. Ishihara looked down on the internal structure of the Crystal Palace, which was densely packed with crystal pillars and crystal walls, which divided the Crystal Palace into countless spaces, and between these spaces, there were a large number of prohibitions, which were interlocking and closely connected, making the Crystal Palace a seamless whole, and the whole body was moved.

Ishihara felt that the structure of the Crystal Palace was a little familiar for a while, and he pondered in his heart for a moment, and a flash of light suddenly flashed in his mind, and he immediately deduced and changed the model of the Crystal Palace, and soon discovered the shadow of the Yin and Yang Returning Array from it.

Sure enough, this crystal palace is built on the basis of the Yin and Yang Returning Yuan Array. And the function of this arrangement is to allow the Crystal Palace to gather, transform, circulate, and use the aura to the greatest extent, even if it is placed in a place where the aura is thin, this Crystal Palace can also create an environment with abundant aura that is no less than that inside the low-level spiritual veins.

In addition, it also cleverly integrates the various functions of the cave mansion, such as cultivation, law acting, alchemy, refining, spirit animal breeding, elixir planting, etc., organically combined with the Crystal Palace.

Good baby, really good baby! Ishihara suddenly showed a surprised expression on his face, just the structure of this crystal palace made him feel that he benefited a lot, and this was indeed the first heavy treasure left by the Xuangui Dao people, the Water Palace Forbidden Pearl.

After obtaining the inheritance of the Xuangui Daoist, the inheritor only needs to cast the forbidden spell to include all the forbidden beads in the Crystal Palace into the Water Palace Forbidden Beads, and these crystal-like materials will turn into clear water and disappear;

This Xuangui Daoist's forbidden mastery is indeed worthy of a generation of grandmasters. Ishihara extended his divine thoughts to the forbidden bead in the center of the crystal palace and got the information in it, and he couldn't help but be impressed in his heart, compared to it, the deity is like the difference between a hacker and a programmer.

It's a pity that this Water Palace Forbidden Bead has not yet been refined, and there is still a lack of some high-level prohibition applications such as space prohibition in it, so it can't store things now, and the contents will fall out every time it is put away. But back then, the Xuangui Dao people had no intention of continuing to improve, so they could only stay and use it as a portable cave for future generations.

But even so, it has already surprised Ishihara, and he finally doesn't have to worry about the cave in the future. And the first treasure made him so satisfied, what is the use of the other two heavy treasures?

Thinking of this, Ishihara immediately couldn't wait to start searching for other treasures of the Xuangui Daoist, and soon found the place where the Xuangui Daoist left the inheritance through the prohibition.

This is the cultivation room in the center of the Crystal Palace, looking along the prohibition, there is an old monk in the shape of a turtle back crane and a fairy wind dao bone sitting on the cloud platform in the center of the cultivation room, and there are three crystal balls on the desk in front of him, which is the inheritance he left behind, but there is no trace of the other two heavy treasures, but according to the Xuan Turtle Dao people, it should also be in this cultivation room.

Seeing the scene in the cultivation room, the smile on his face became brighter and brighter, and as soon as he pinched the magic trick in his hand, the tight and seamless crystal wall in front of him suddenly separated, revealing a passage leading directly to the cultivation room.

However, for Shi Yuan, who controlled the Crystal Palace, he already knew exactly what these three tests were, the first of which was the illusion, and the perseverance and hard work of the test were the basic requirements, and they also needed to be dexterous and careful, and act carefully and rigorously in order to find the hidden clues left by the Xuangui Dao people from the illusion to break the illusion, otherwise even if they knew that this was an illusion, they would be forcibly trapped in it and could not be freed.

And the second test is dangerous, and the test is the ability to calculate. There are 9,999 Yaling crystals in this testing ground, which will continue to excite the Red Absolute Divine Line attack tester like a laser according to a certain law, and only by relying on strong computing power can calculate the attack route of the Red Absolute Divine Line in the shortest possible time, and then can you avoid being damaged, once you are hit too many times, the test will be considered a failure.

The third test is both simple and dangerous, and it tests the vitality force, that is, the abundance of life essence. Relatively speaking, the Heavenly Machine Calculation is the most life-consuming thing, it can be said that a monk with a thin life essence, even if he has a high talent, it is difficult to major in the Heavenly Machine Calculation, and the Xuangui Daoist does not want his inheritor to die after just a few years of accepting the inheritance.

Therefore, the third test is to be directly teleported to a forbidden space to be absorbed life essence, and the amount of essence absorbed will not hurt the foundation for those who are abundant, and it will be recovered quickly, but for those who are thin, it is really fatal.

The three tests are all based on the Jindan period as the lower limit of strength, which can carefully test whether a monk has the talent for heavenly calculations, the Xuangui Daoist can be described as well-intentioned in this, but it is a pity that it can be regarded as flattering to the blind man, Ishihara unceremoniously directly suspended the prohibition in the test, and walked to the cultivation room of the Xuangui Daoist with ease.
