Xiang Yun walked out of the inner demon corridor.

A hall appears in front of you.

Xiang Yun found the layout of this hall very interesting, with three huge mirrors placed in the center, each of which could be adjusted in the direction of the angle.

In one corner of the hall are neatly placed eighty-one crystal stone tablets.

Besides, there was nothing else in the hall, no hints, no clues.

"Well, is it another puzzle?"

Xiang Yun quickly observed the situation on the façade of the hall.

Since this scene is called the Hall of the Wise, the puzzle must be more difficult to solve.

It is different from the brainteaser puzzles in the previous scene, which obviously cannot be solved with a little wit, but requires knowledge, wisdom, understanding, and experience!

Even if you can survive the fire in the last level, you can solve all kinds of puzzles.

That only shows that you have strong perseverance and a strong mind.

As the saying goes, knowing is knowing, and not knowing is not knowing.

Personal will is not useful at this level.

In short, it's hard, it's very hard!

Generally, the trialists who participate in this secret realm, few can pass the second level, either the knowledge reserve is not enough, or the personal knowledge is not enough, or the understanding is not good, any lack of quality will lead to failure.

Xiang Yun was not in a hurry to launch the Book of Heaven.

Because if there are more intelligence clues, the operation of the Book of Heaven will be smoother.

He first inspected the crystal steles neatly placed on one side, and he found that on each crystal stele, a complex pattern appeared densely packed.

If you look closely, you will find that the pattern is a set of Yuan Li in the meridians, very detailed, not only marking each of the most tiny Yuan Li meridians, but also clearly expressing the flow and operation of Yuan Li.

Xiang Yun saw at a glance that the patterns were abstract and overlapping, and they were incomplete.

He began to look at the other eighty steles and found that the situation was exactly the same.

Each crystal stele has a diagram of the movement of the sub-meridians, but without exception it is abstract, broken and incomplete.

See this.

Xiang Yun roughly understood what he was going to do.

He had discovered the relevance of the patterns of the eighty-one crystal steles.

If you don't guess wrong, you have to use eighty-one meridian operation charts to try to piece together a complete meridian operation chart, and how to connect these meridians has been running with yuan force, which obviously involves quite esoteric knowledge.

There is one more problem.

Even if you grasp the content of the puzzle.

And in what way should it be unraveled?

It's impossible to memorize all these meridian flow charts and then put them together one by one like playing a jigsaw puzzle, right? This kind of thing may be possible for Xiang Yun.

But it is also very difficult.

Because Xiang Yun has already discovered that the pattern seen through the crystal stone with the naked eye is actually folded!

Therefore, the way of expression is very abstract, and the detailed patterns stored in the crystal are more complex than imagined, even if they are deduced one by one using the Book of Heaven, it will take a lot of effort.

For others.

It is an almost impossible figure to complete.

The meridian movement diagram of the crystal stone pillar is already very complicated.

It takes a lot of time for each painting to be perfectly mastered and reproduced.

What's more, what can be seen with the naked eye is only a simple abstract drawing, and even if someone has enough time to memorize them all, there is no possibility of stitching them into a complete picture.

"There must be a way to expand the whole picture. ”

"I think the key to stitching the meridian operation diagram must be on the bronze mirror. ”

Xiang Yun's gaze fell on the three mirrors, but he was not in a hurry to go over and crack the secret of the bronze mirror, he walked in front of the crystal stone pillar in turn, and in the process, he activated the Book of Heaven and wrote down the operation diagram in it.

"Interesting. ”

Xiang Yun soon discovered an interesting thing.

Eighty-one running diagrams have been deduced and spliced by the soul of the Heavenly Book, and finally formed a complete pattern of three versions from simple to complex.

The exercises shown in the three pictures are actually defensive exercises, more precisely, a method of protecting the body's vitality.

Thirty-six drawings make up a set of "The Qi of the Earth Protector".

Sixty-four drawings constitute a set of "Tiangang Protective Body Qi" operation chart.

Eighty-one diagrams constitute a set of "Mixed Element Protective Body Qi" operation diagram.

The difficulty ranges from low to high.

The exercises are also from low to high.

Xiang Yun believes that as long as he completes any one, he should be able to pass this test, and maybe have a chance to get this set of exercises.

Everyone who enters this secret realm will definitely encounter different challenges, and the exercises encountered by others will definitely be different from Xiang Yun's, so this kind of thing is likely to have only one chance.

Xiang Yun didn't want to miss it.

Although the eighty-one drawings have been put together under the influence of the Book of Heaven, it is still a challenge to use the mirror in the center of the hall as a key to unlock the secrets of the eighty-one stone tablets.

Xiang Yun glanced at the three bronze mirrors.

He soon discovered the mystery of the bronze mirror.

These bronze mirrors seem to be able to release light by instilling Yuan Force, and the beam of light released from the bronze mirror is the key to solving the puzzle.

The light can unfold the whole picture in the crystal.

Light connects eighty-one crystals.

Xiang Yun stood in place, closed his eyes, and deduced.

"I see!"

"I know what to do!"

Xiang Yun walked to a stone stele, picked up the stone tablet weighing thousands of catties with both hands, placed it in a calculated position, carefully measured the distance and adjusted the angle, and then the next stone stele.

In this way, the positions of the eighty-one stone tablets were re-arranged.

At this moment, the crystal stele is distributed around the three bronze mirrors in a circular manner, and the position of their distribution looks chaotic, without any law at all.

"That's it!"

"Then it should be the time to witness the miracle!"

Xiang Yun injected Yuan Li into a bronze mirror, and from the mirror surface of the bronze mirror, a strong beam of light was suddenly released, and Xiang Yun used the beam to shine on the edges and corners of one of the crystal stone tablets.

The intense light was refracted by the crystal ten times the edges and corners, and more than a dozen beams of light were released to the surroundings in an instant, and above the position of each beam, there was a stone tablet that happened to be illuminated, and several stone tablets continued to refract, instantly allowing dozens of stone tablets to be illuminated by the light.

Xiang Yun also activated the second bronze mirror and the third bronze mirror.

The light beam was injected into the crystal stele array, and according to the order of the exercises, the reflection and refraction between these steles were carried out in turn, and finally the eighty-one crystal steles were lit up by the light, and the folded group was completely unfolded.

"Is it done?"

Xiang Yun looked at the brilliant scene in front of him and asked.

At this time, each stone tablet released light upwards, and these rays of light were condensed in mid-air, instantly outlining a complete diagram of the operation of the Yuan Force, and supplementing the mental method to form a complete set of exercises.

It worked!

Xiang Yun successfully solved this puzzle!

He only used it for an hour, and it seemed very simple, but in fact it was definitely not as simple as he thought.

The first thing to do is to make sure that each crystal stone tablet is in the right place.

This alone is very difficult, because any deviation in the position of any stone monument can lead to failure.

Secondly, it is necessary to ensure that after the beam of the bronze mirror is shot, the crystal stele is lit in the correct order, and the speed of light cannot be captured, but the crystal stele can react according to the order in which it is lit.

This order must be the order of the exercises.

In other words, any misspelling of any part will lead to a direct failure.

The most troublesome thing is that even if there is a failure, you don't know where the failure is.

Because mortals can't see the trajectory of light at all, you can imagine how difficult this level is.

Except for Xiang Yun in Xichu University, I am afraid that it is difficult for a second person to do it, and the exercises that others can put together a thirty-six pictures are already very good.

Xiang Yun quickly memorized the content of the exercises presented.

This is a set of exercises for cultivating the Yuan Force of the body, which belongs to the category of defensive exercises, and it seems to be an extremely superior ancient technique, which is still very useful to Xiang Yun.

And at the same time as Xiang Yun solved the puzzle.

A door opened in the hall.

Outside, the sun and the woods are clearly the gateway to the final scene.

It's so fast, the first two scenes add up, and it only takes more than an hour!

Xiang Yun remembered that the third scene was the Competitive Island, but no one should have arrived at the Competitive Island yet, he was definitely the first, so he could go in and prepare well and give the others a big surprise!
