When all the words on the stele were submerged into Qi An's eyebrows, the golden light in the sky converged, and the obelisk, which was as bright as a miracle, gradually dimmed, and the surroundings were no longer a night scene, although there was not a ray of sunlight to be seen, it was also like day, like a misty morning in a deserted suburb.

Qi An stood in place, he didn't see any movement for a long time, his mind was all on the [Array Explanation Sutra] presented in his mind, although it was obscure and difficult to understand, but if he could see a little bit of fur from it, it would make him feel like he was suddenly opened, and he was overjoyed.

[Array Explanation Sutra] mainly talks about the knowledge of the formation, from shallow to deep, with the formation into the Dao, expounding the truth of the world, and analyzing the avenue of the universe, it can be said that it is the most vast, the most mysterious, and also the highest level of the ancient Dao Sutra that Qi An has come into contact with so far, even if it is the [Seven Absolute Sword Techniques], it is far inferior.

Although the [Seven Absolute Sword Techniques] also originated from ancient times, it is only a cultivation exercise, and it is natural, not the reason, as long as it is cultivated, it can have absolute strength.

And [Array Explanation of the Tao Sutra] is just the opposite, do not talk about cultivation, do not talk about methods, only tell the essence of all things in this heaven and earth, stimulate imagination, expand thinking, it seems to be talking about the formation, but in fact it is the formation into the Tao, all-encompassing, covering a wide range, if you can fully comprehend, you will not only master the formation, but in many aspects can be beneficial, as for how much you can comprehend, it all depends on each person's understanding.

The whole article is 16,384 words, every four words into a sentence, every sentence is mysterious, a total of 4,096 sentences, only the first dozen sentences are still easy to understand, relatively easy to understand, the more later, the more obscure, and even a variety of ambiguities, I don't know which one is the correct explanation, and those who do not have great wisdom can not be thorough.

Soon, Qi An encountered a bottleneck, after thinking for a long time but not being able to get it, he was bored, and finally woke up from his state of thinking, only to find that he was still standing in front of the quaint stone monument, and there was no movement around.

But what is very strange is that he clearly saw that the words on the stone tablet automatically flew up and rushed into his mind, but now when he looked at it again, the stone pillar inscription was still the same as when he first saw it, and the handwriting was still there, and nothing had changed, as if the scene just now was just an illusion.

But Qi An believed that it was definitely not an illusion, a whole [Array Explanation Sutra] was completely engraved in his mind, and he understood the meaning of each ancient text, and it seemed that through this supreme Tao Sutra, he was proficient in this ancient scripture, and he knew its meaning just by looking at its shape.

Qi An turned his eyes around, and what he saw was gray stone tablets of different heights and shapes, engraved with strange line symbols, some simple and complex, none of them were the same.

"Huh?"

Qi An's gaze was cast on a low gray stone stele, it was not far away, half a human height, it seemed to be indistinguishable from the other stone tablets around it, it was extremely inconspicuous, but the pattern on it immediately attracted Qi An's attention.

"...... this?"

Qi An raised his feet and walked towards the stone monument, with a mixed expression of joy and shock on his face.

The surface of these stone tablets has different patterns, when Qi An first entered this place, none of them could be understood, and they did not understand their meaning at all, but after learning about the [Array Explanation Sutra] and a little research, Qi An found a clue.

In the case of the stele that aroused his interest, the pattern on it turned out to be an extremely simple pattern, as if something was missing, and it did not take shape.

Qi An happened to comprehend a little bit of fur from the dozens of sentences in front of the [Array Explanation Sutra], and he could barely see a little eyebrows, so he was attracted by this stone tablet pattern and walked towards it.

Qi An stared for a long time, frowning and pondering, and soon after, he smiled and whispered to himself: "Sure enough, there is a missing stroke." ”

He raised his arm and reached forward, using his fingers as pen and qi as ink, his fingertips lightly slicing over the surface of the gray stone tablet, filling in what he thought was missing.

Suddenly, the pattern on the stone tablet flowed, and bursts of mysterious aura burst out, as if spirituality "lived", as if it had been given life by Qi'an.

At the same time, the gray stele also began to change, and the color became white and flawless, like beautiful jade, and the whole body exuded a faint halo, which immediately distinguished it from the other steles around it and attracted attention.

And all of this happened at the moment when Qi An completed the broken formation, and all kinds of visions appeared out of thin air, which was magical.

"I see!"

Qi An witnessed this scene, and then looked at the other stone tablets around him, and he had a realization in his heart.

"It turns out that these countless steles are all tests left by the three absolute old men, and each stele is a formation problem, if it can be solved, the stele will change. ”

Once he figured out the meaning of the existence of these gray stone tablets, Qi An knew the painstaking efforts of the three absolute old men, the [Array Explanation Dao Sutra] he passed down was only a general outline of the theory, and there was no specific application method, and he had to rely on these countless gray stone tablets to crack and study step by step, in order to master the formation avenue.

Just listening to the theory of the Book of Heaven, it seems that I understand it, but in fact I don't really understand it; I just learn the ready-made patterns and formations, but I don't know why they are, and when I encounter a change in form, I don't know what to do.

Neither of these is advisable, and only the combination of theory and practice is the most effective learning method.

Theory guides practice, and practice in turn confirms theory, and the two deepen and promote each other, and finally reach a thorough realm that is both inside and outside.

This is the real intention of the three absolute old men to set up these countless stone tablets.

Cracking a stone stele, Qi An was quite pleased, and looked at another stone tablet not far away, but after dozens of breaths, Qi An shook his head and looked away.

This second stele is also a broken formation, but with Qi An's current ability, he still can't figure it out, and he can barely see one or two out of ten, how can he crack it?

Qi An looked around again, looking for a stone tablet that he could crack, and finally found one, not far from the left, just because it was relatively short and inconspicuous, so he didn't find it at the first time.

The pattern on this stele is concise and clear, not complicated, it seems to understand whether it is understood, if you spend some time studying, maybe it is expected to be cracked, Qi An will be patient, carefully ponder, from time to time with the heart of the silent [array of the Tao Sutra] to confirm each other, looking for a way to break.

After a long time, Qi An finally stretched out his finger and slowly scratched on the surface of the stele, and looked forward to the vision with joy on his face, but the result was disappointed to him, the stele did not change in any way, and the lines he drew with his finger slowly disappeared, and finally left no trace.

"Alas——! wrong!" Qi An sighed in disappointment, shook his head, and continued to ponder.

I don't know how long it took, Qi An's face finally showed a happy expression again, he carved the stele with his fingers, drew a stroke, and at the same time erased a superfluous with his palm, the broken formation was instantly formed, the light was shining, the color of the stele also turned from gray to white, and the halo appeared, but this time it was right.

It was not easy to solve another problem, and it took several times as long as before, but Qi An also had a little more understanding of the formation in the process and improved a little.

Qi An, who was excited, wanted to make persistent efforts, but suddenly remembered that he had entered this mysterious space alone for a long time, and Moro did not react at all, and the outside world did not know if anything had happened, if he did not confirm it, it would be difficult to feel at ease.

So, Qi Anqiang suppressed his mood of wanting to participate in the formation and took out the wordless iron card on his body.

Drawing the iron plate pattern with his fingertips, and using his true qi to attract the inner spirit pattern, after a while, a rippling circular light curtain appeared in front of Qi'an, just like when he came, he only needed to enter and leave here.

Qi An did not hesitate, stepped into the circular portal, and when he came out, he was already in the small courtyard, and the surrounding scenery was exactly the same as when he left, without the slightest change.

"Moro?" Qi An called softly, trying to confirm the other party's current condition.

"I'm here!" Morro's voice immediately sounded, and it seemed a little solemn.

Without waiting for Qi An to ask, Moro took the first step and said, "After you stepped into the void portal, I was firmly imprisoned by a mysterious force, imprisoned in this iron card, unable to speak, unable to release divine thoughts, extremely depressed, I don't know what you have experienced. ”

This is roughly consistent with Qi An's conjecture, it is estimated that these three absolute old men are much more powerful than Mo Luo, in the place of inheritance, except for Qi An who holds the token, the rest of the people, regardless of the physical primordial god, must be inexplicably suppressed and must not be moved.

Qi An gave a general account of everything he had experienced when he entered the inheritance space, and asked Moro about the origin of the Three Peerless Old Men, but Moro had never heard of this name, obviously very old, before the invasion of the Heavenly Demons.

Under the invasion of the Heavenly Demon Army, countless powerful and prosperous Xiuzhen sects were destroyed, and the human Xiuzhen world suffered an unprecedented tragic blow, and countless magical powers and secret techniques were lost, which almost caused the rupture of the entire Xiuzhen civilization, making the current Xiuzhen world slump, far less prosperous than in the past.

Later generations used this battle as a basis to refer to the previous era as antiquity, and the latter as the present world.

Obviously, the Three Absolute Old Men are the peerless power of the Ancient Cultivation Realm, and his life era is far before the Great War of the Two Realms, and it is reasonable that Moro has not heard of his name.

Subsequently, Moro asked about the [Array Explanation Sutra], and Qi An did not deliberately hide it, so he wanted to recite a short paragraph for him, but when the words came to his mouth, he couldn't say a word, as if he was stuck in his throat and couldn't make a sound.

This matter is strange, for some reason, Qi An couldn't figure it out, so he could only squat down and use his fingers as a pen to write on the ground.

The strange thing happened again, and before a word could be written, the traces on the ground disappeared without a trace, as if they had never existed, much to the surprise of Qi An.
