In the depths of the swamp more than five hundred miles away from Youning City, Gu Xiuyun's body was like a phantom, diving into the dark lake.

After a while, they came to the pool of spiritual fluid at the end of the cavern.

The pond was empty, except for the smooth stone wall, there was no foreign matter, the large array of the spiritual liquid pool had not yet been opened, and only with the stalactites above, a few drops of stalactite spiritual liquid could not be condensed in a year.

"It's a pity that this spiritual liquid pool, if I can understand the pass and open the big array, I can cultivate in the cave all year round, and the effect should be no less than the quiet room of the fourth uncle. Looking at the complex formations on the stone wall, Gu Xiuyun sighed.

The Great Array of Spiritual Liquid Pool is extremely complex, far from being comparable to the Misty Array, if the Misty Array is considered a low-grade formation, then the Great Gathering Array of Spiritual Liquid that gathers stalactites is at least a top-grade formation, and the gap between it is like the gap between the Douxiao Realm and the Washing Pulse Realm.

Gu Xiuyun urged the spirit tortoise black armor stick, trying to deduce the formation patterns on the stone wall, and after a while, he felt dizzy, as if his mind was a little unbearable.

"Sure enough, the foundation of the formation is too poor, and the mystery of the formation of the spiritual liquid pool is forcibly deduced, which is too oppressive to my mind. Gu Xiuyun shook his head and sighed, "That mist array is quite simple, but the spiritual liquid pool array is a hundred times more complicated, and it is even more difficult to deduce, which is not what I can do now." ”

Heavenly deduction is not omnipotent.

Any deduction must have a certain foundation in order to be extended, if it is just a simple trace, you only need to sense the mystery of the heavens, and you will naturally understand, because there is no mystery.

But the formation, the change of the poor heaven and earth, contains the power of heaven and earth, even if it follows the guidance of the heavenly machine, it is still mysterious and mysterious, like a mess, you must analyze it yourself, to understand, in order to truly understand.

If Gu Xiuyun had systematically studied the formation and had a solid foundation, and now he had comprehended the Great Array of Spiritual Liquid Pool, there would still be three points of hope.

But he only had a little understanding of the Heavenly Mandate Clan in his previous life, and he didn't know much about the formation, in the final analysis, he was a layman, and using such a foundation to comprehend the advanced and profound formations of the Spirit Liquid Pool Great Array was tantamount to an idiot's dream.

"That's it, let's open up the Heavenly Pass first!" Gu Xiuyun didn't think much about it.

I saw that his hands were connected, and several spiritual powers poured into the formation veins, opening the mist array that guarded the spiritual liquid pool.

Soon, the mist shrouded the entire cave, Gu Xiuyun sat down cross-legged, closed his eyes and breathed for a moment before he began to operate his spiritual power and try to open up the Heavenly Pass.

In his senses, where the spiritual veins are located, there is an independent heaven and earth, but beyond the heaven and earth, there is still a broader sky.

His natal heavenly pass seems to be the highest layer of the mille-feuille, and in the depths of the mille-feuille, there are more hidden heavenly passes, but because the realm is not enough, it cannot be reached.

But vaguely, Tianguan is like a bone, which only occupies a part of the body, and he has to open up each bone and run through the entire body in order to make himself completely full and complete.

"Tianguan, what is it?" Gu Xiuyun asked in his heart.

No one can answer this question.

Since ancient times, whether it is the demon race or the human race, it is to ignite the spiritual vein, and then open up the Tianguan, and practice step by step to the peak, what is the Tianguan?

Maybe only after reaching the top can you understand.

Following the perception in his heart, Gu Xiuyun filled his spiritual power into the depths of Tianguan, and gradually, his spiritual power seemed to have hit a big mountain, the mountain was tall and handsome, and when the spiritual power river was blocked in front of him.

At this moment, Gu Xiuyun's heart echoed in his heart and asked for the truth, one by one ancient words flickered in the depths of his soul, and in front of him, the spirit turtle black armor sign danced in the air, drawing lines and lines.

Each ancient word contains infinite changes, if only a single ancient word, it is impossible to understand the mystery of the practice of asking the truth, only by composing them into a paragraph, can we understand the true meaning.

"The physical body is like a ferry, and the way of cultivation is to use the physical body as a carrier to ferry to the other side. But in the depths of the avenue, it is like the ocean under the storm, full of turbulent waves, and if you are not careful, the ship will be destroyed and people will die, so the way of cultivation must first build a perfect physical treasure ship. ”

Gu Xiuyun followed the ancient words in the Taoist scriptures and understood the true meaning of opening the pulse realm.

The Yuan Ling Washing Pulse Realm still belongs to the stage of igniting the spiritual vein, and only when you step into the Open Pulse Realm can you be regarded as a true cultivator.

And the first step of cultivation is to open up the Heavenly Pass, open the physical treasure, and let yourself have enough strength to walk to the other side of the avenue.

"Legend has it that there are seven kinds of avenues between heaven and earth, supporting the immeasurable world, and the Dao Venerable sacrifices himself to become a Taoist, evolves the immeasurable light, and ignites the mortal dust. ”

Gu Xiuyun suddenly thought of this passage.

This text came from the Danjing Pagoda and was recorded on the first page of the ancient text explanation, and after Gu Xiuyun saw it, he didn't care.

But at this moment, he once again comprehended the truth-seeking chapter, and even realized this passage in the Taoist scriptures, and at the same time, the Tianguan Mountain in his body trembled, and seemed to be constantly disintegrating under the washing of the water.

"Perhaps, there really is a Dao Venerable in the world, otherwise, how would the Great Dao of Cultivation be passed down?" Gu Xiuyun whispered in his heart, "That kind of existence is too far away from me, so let's concentrate on comprehending the method of breaking the level." ”

Ancient characters continued to circulate in his heart, deriving one method after another, but they were all abandoned by Gu Xiuyun.

The Asking for Truth chapter contains infinite mysteries, and the same text can comprehend thousands of methods, but only one is truly suitable for Gu Xiuyun.

He didn't have the supernatural powers to know his meaning in his previous life, so he could only rely on his own deduction method.

After a long time, a concise exercise flowed in his mind, and the moment he saw this method, Gu Xiuyun felt an invisible sense of comfort, as if every change in this method was perfectly in line with himself.

"That's it!"

Gu Xiuyun closed his eyes, his spiritual power followed the magic technique, and the torrent-like waves of spiritual power dispersed into countless small streams, sweeping through the Tianguan Mountain.

To open up the Tianguan, you can't use brute force to force the collision, otherwise it will only make the Tianguan collapse and the avenue will be cut off.

And the method of breaking the level is actually the method of refining the Tianguan.

As the so-called spring rain moistens things silently, every Tianguan has a corresponding refining method, and the first Tianguan that Gu Xiuyun encountered was the Yamagata Pass.

As the spiritual power stream melted into the depths of the mountain rocks, young shoots grew out of the ground, and the seeds of these young shoots originally existed in the depths of the Yamagata Pass, but there was no spiritual power to nourish them, so they slept underground and did not show any traces.

Spiritual power is like spring rain, blending into the soil and stones, moistening the earth and moistening the seeds, so that the grass grows and the warbler flies, and all things recover.

Yamagata Pass, like a real mountain, sprouted countless shoots, and those shoots quickly grew up and became towering trees, devouring the nutrients of the mountain rocks and splitting the intact mountain into pieces one after another.
