The stone walls around the stone chamber are covered with dense runes. In the corner, there is also a flag. Various array materials are piled everywhere.

An invisible force bound most of the Yin Qi and earth evil Qi in the stone chamber, and only a small part leaked out and spilled to the outside world.

At this time, the stone chamber can no longer be regarded as the Yang world. To a large extent, it can be regarded as the projection of the underworld in the Yang world.

In the outer passage, Meng Zhang was besieged by a large number of ghosts. But around the stone chamber, it was so clean that half the ghosts could not be seen.

The reason is very simple. There is a special force in the stone chamber, which makes ghosts dare not approach.

Meng Zhang did not rashly approach the past, but carefully observed it from a distance.

After watching for a long time, Meng Zhang finally saw some famous things.

A Dharma array is arranged in the stone chamber in front of us. The power of the Dharma array, however, seeped out a lot, affecting the outer mine path.

Meng Zhang has good eyesight and rich knowledge of the Dharma array. After a lot of effort, he finally recognized the origin of the Dharma array in front of him - the yin-yang reversal array.

Yin Yang reversal array is a very typical ghost array, which is rarely touched by ordinary practitioners.

In addition to the core part, the rest of the yin-yang reversal array has many changes.

Different materials and techniques of array arrangement lead to different levels of array.

The large array in front of us is at least a second-order normal array. It is clear that the deployer has worked hard.

When he did not enter the mine, Meng Zhang observed the changes of the surrounding terrain with his broken eyes, and simply measured the direction of the earth vein with the skill of geomancy.

The expert who arranged this yin-yang array made full use of the geographical advantage. The underground evil spirit and the resentment of thousands of tragic dead in the mine have become the material for this person to arrange the array.

Of course, to set up such a Dharma array, it costs a lot of other precious materials.

Meng Zhang's false Dharma eye can't completely see through the second-order Dharma array. However, with his rich array knowledge and what he saw and heard all the way in, he guessed the situation of the array.

More than ten years ago, the mine was broken by sand monsters, and many people died miserably. The mine cave is just where the Qi of the earth evil spirit gathers.

Judging from the leakage of Yin Qi, this array has been deployed for at least ten years.

It should be that shortly after the accident, an array expert among the ghost friars arranged this array here by taking advantage of favorable conditions.

The Yin Yang reversal array has many functions. It can be used for defense, attacking the enemy, feeding ghosts, and cultivating some skills and spells for ghost friars.

The function of this yin-yang reversal array is not the above, but a treasure used to cultivate a certain Yin attribute.

As for the ghosts and Zombies Meng Zhang has encountered along the way, it is the massive Yin Qi leaked from the yin-yang reversal array that has caused the impact in the mine.

The creation of those ghosts and zombies is not the original intention of the constructor of the array, but an accident caused by the leakage of Yin Qi.

Under ideal conditions, the yin-yang reversal array can forcibly reverse a certain area of the Yang world into the underworld.

This second-order array is far from being able to do this, but it is more than enough to make the environment of the stone chamber similar to the underworld and use it to cultivate some Yin treasure.

Meng Zhang was very excited when he thought of the treasure cultivated by the second-order Dharma array for many years.

It seems that the greatest harvest of his adventure should be in the stone chamber. If it's not too dangerous, you can try to collect the treasure.

With his false magic eye, Meng Zhang tentatively walked a few steps to the stone chamber.

The original function of this dharma array to confuse invaders seemed to him as if it did not exist.

If you change to an ordinary cultivator, as soon as you get close to the stone chamber, it's like walking into a maze. You have to be trapped and die in it.

After entering the array, Meng Zhang's false magic eye finally found the treasure.

In the center of the stone chamber, there is a dark pool. The pool is only the size of a washbasin. There is a thin layer of black liquid in the pool. On top of the black liquid, there are a few drops of dark silver liquid floating.

This is, this is the jade soul liquid, which is used to strengthen the spirit. It can assist the nine perfect friars in the foundation building period to attack the treasures in the golden elixir period.

During the Qi refining period, the monk's main work is to quench the true Qi and penetrate the acupoints and orifices of the whole body. For the training of the divine soul, only a little dabbling.

However, when the monks enter the foundation period, they must spend a lot of energy to strengthen and exercise the spirit.

Especially when the foundation building period breaks through the golden elixir period, the perfection of the soul is a necessary condition for crossing the barrier.

In the cultivation world, there are very few materials and pills that can be used to supplement and strengthen the spirit.

It's ghost friars. They have some specialties in strengthening spirits. This is also an important reason why ghost friars are treated better than demon friars in the cultivation world.

Jade soul liquid is refined by ghost friars with a secret method and can be used to supplement the treasures of gods and spirits.

The black liquid in the pool is actually the residue produced in the process of refining jade soul liquid. The real jade soul liquid is only a few drops of dark silver liquid.

The quantity and quality of this jade soul liquid are far from enough to strengthen the divine soul and impact the golden elixir during the foundation period. But for Meng Zhang, it is of great use.

Of course, this is not used by Meng Zhang himself. Although his spirit is powerful, he is only a friar in the period of Qi refining after all. If you rashly use the jade soul liquid in front of you, you will only be too weak to make up and become possessed.

These drops of jade soul liquid are of great use to him.

Meng Zhang was not ready to gain the treasure cultivated in the Dharma array. Now he found that the treasure was jade soul liquid. He said he must get the treasure in his hand.

Based on Meng Zhang's array knowledge, the current yin-yang reversal array must be maintained frequently in order to maintain the normal operation of the array.

However, judging from the situation of the Dharma array, no one has maintained the Dharma array for at least several months.

Therefore, more and more Yin Qi leaked from the Dharma array, which is actually a great waste.

Meng Zhang's purpose is not to break the battle, nor is it necessary. If he simply wanted to take away the jade soul liquid, Meng Zhang thought for a long time and finally came up with a clever way.

Yin Yang reversal array aims to reverse Yin and Yang. It has two array eyes and scores Yin and Yang. If you want to go deep into the array, you must use the force of yin and yang to fix these two array eyes at the same time.

Meng Zhang has only one person and seems unable to hold two array eyes at the same time. But the trick he came up with was to get the spirit out of the body and use the spirit and the body at the same time.

The spirit belongs to Yin and the flesh belongs to Yang, which can just meet the needs. The two forces of yin and yang are launched at the same time.
