The most difficult and dangerous part of this illusion array is that...

It will magnify a certain past experience of yours infinitely.

The more dangerous those memories you think you've long forgotten are, the more dangerous they become.

Because you had absolutely no defenses, but when this memory that you had no defenses against was brought to the surface by the great formation...

Your spiritual memories will be suppressed to that past stage.

Breakthrough, the soul becomes clear and free of impurities.

If one falls into depravity, the seal within the great formation, which was originally an illusion, will become a real entity forever, and one's cultivation will never advance again.

This is also why the requirement for all the ancestors to jointly control the great formation is made at the age of thirty.

The hardest enemy to defeat in this world is not the enemy, but the one's own conscience.

Ask your own heart.

The grand formation was activated the moment the brothers, Ye Boqi and Zhang Youdao, entered the secret realm.

For so many years, the Zhang family ancestors had devoted all their energy, except for creating human beings, to divination arrays.

If the human race can master the method to break this great formation, they will gain absolute initiative in the realm battlefield.

But this process is extremely difficult.

The enormous array in the boundary battlefield is a true innate source array.

A naturally formed formation.

The alien races used this naturally formed formation as a springboard to launch a massive invasion of the Central Ming Empire.

It was precisely because of the existence of this natural formation that the alien races were able to retreat safely back into the battlefield of the boundary.

The pursuing human warriors could only watch helplessly as the alien race retreated safely.

The invasions of foreign tribes into the imperial land will not stop; as long as they accumulate enough strength, they will surely return.

Therefore, deducing the formation is of paramount importance.

As a result, a large number of martial arts techniques based on illusion arrays and combining killing and harmonizing have emerged on the imperial land.

Despite investing a great deal of effort, the formation still could not be broken.

Even with the Nine Heavens Profound Dao Sect's resources, they have only managed to break through one-tenth of the great formation's power.

Therefore, in Zhang Mancang's view, even if Xiao Boqi can overcome the first stage of inner demons, the process will not be too fast.

Because he himself almost fell into the illusion and couldn't wake up back then.

He knew that his cultivation and the refinement of his soul over many years were far beyond what the current Qi Boqi could compare to.

Just as he had finished putting his three-year-old son to sleep and was about to send Zhang Dachou home, a dull thud startled him.

The inner demon has been broken!

It only took one hour!

Just as he was shocked that Yi Boqi was able to break through the inner demons induced by the formation in such a short time.

Another extremely dull thud was heard.

Having just broken through the mental blockade, Yi Boqi instantly found a barely perceptible flaw in the formation and broke the scene it had created on the spot.

Then we arrive at the mid-stage of the formation, where the inner demons regenerate.

The second challenge is called "Inner Demon Rebirth," which is a further evolution of the first challenge, "Inner Demon Chaos."

Human inner demons are complex, but they can be summarized in just two words.

Regret, guilt.

Regret can make you feel remorseful, but guilt can instantly trap you in a quagmire of self-blame from which you cannot extricate yourself.

So the most fatal part of this second hurdle is that it triggers the guilt in your heart.

If even a hint of remorse is shown, the soul will be instantly devoured by the formation and slowly sink into oblivion.

In Zhang Mancang's plan, after Xiao Boqi breaks through the first barrier, he will pause the operation of the great formation to give him time to recover and adapt.

To his utter surprise, his son-in-law was so fierce.

After overcoming the first obstacle, the inner demon, he broke through the second obstacle without even hesitating or pausing.

Now, after breaking through the second barrier, they have begun to reverse the power of the formation.

This... isn't this a bit too outrageous?

It took the entire Daoist sect of old immortals so long to figure this out, and you broke it in such a short time.

Doesn't this make us old folks seem a bit incompetent?

Is there no justice left? Is there no law left...?

From the mountaintop, it appears that Xiao Boqi has now reached the center of the entire formation.

"Damn it, we tried to use the power of the formation to make this kid grateful to us on our first meeting, but Feng'er saw through our plan and we made a fool of ourselves."

"I was planning to teach him a lesson inside the secret realm's grand formation, then reveal myself when he couldn't hold on any longer and give him some pointers, but this kid actually..."

Zhang Fugui, holding a teacup barely larger than a fingernail, shook his head repeatedly, looking displeased.

"Why is it so difficult to become a respected ancestor?"

As he spoke, he turned to look at Zhang Mancang, who was standing to the side.

"Let the Nine Heavens Mystic Guards enter the formation. I don't believe this kid can really reverse the formation that we spent so long breaking in such a short time."

"What if the son-in-law really succeeds in comprehending it..."

Zhang Mancang's words surprised Zhang Fugui, who then stuffed the small teacup into his sleeve.

"That only proves that we are all useless."

After closing his eyes, the twenty-one star cores within his dantian arranged themselves into an extremely mysterious formation.

Below the star core, the vast Milky Way twinkled with starlight, reflecting the brilliance of the twenty-one star cores above.

After breaking the pear-shaped formation with a wave of his hand, Xiao Boqi sensed a trace of the source formation's aura.

When he acquired the seven stars of the Azure Dragon Divine Soil, he began to comprehend the Origin Array method under the guidance of the Book of Stealing Heaven.

The magic array, born from the origin of heaven and earth, is the ancestor of all magic arrays in the world.

No matter how far the formation has been deduced later, it still originates from the understanding of the original formation.

According to the Book of Stealing Heaven, the many schools of formations in the world have only comprehended one of the endless formation principles within the Origin Formation.

Once you understand the Origin Array, you can break any array in the world with a wave of your hand.

However, comprehending the Source Array is too difficult. Despite the Stealing Heaven Divine Book constantly stealing the power of the Source Array, Xiao Boqi's progress in comprehending the Source Array is still very slow.

Later, in order to speed up the comprehension of the Source Array, Xiao Boqi handed over the Source Array diagram copied from the stars to the Daqi Array Hall.

In recent years, the most important task of Daqi Array Hall has been to comprehend and decipher the source array.

Just after the twenty-one star cores were arranged in formation, the Heavenly Stealing Book, which had been silent for a long time, moved.

With a whoosh, the huge pages of the book flipped rapidly, and the divine soul of Qi Boqi, who sat cross-legged above the Book of Stealing Heaven, quickly made hand seals and performed calculations in accordance with the flipping of the pages.

Each time a hand seal is formed, a mysterious force is injected into the illusion array.

The twenty-one star cores also constantly changed their formation as the Book of Stealing Heaven was turned.

The current star core is like an abacus in Jin Mantang's hands.

With each change, Xiao Boqi's understanding of this grand formation increased by one point.

Time flows slowly by.

After an unknown amount of time, Ye Boqi, who had been keeping his eyes closed, suddenly opened them.

But at this moment, the great formation was in his eyes.

It is transparent.
