Four Symbols Illusion Formation

However, the moment Su Fang stepped into the underground palace, he immediately sensed that something was wrong.

Light and shadows swirled.

In an instant, the scenery around him changed drastically.

When he came back to his senses, where was the underground palace?

Looking around, he found himself surrounded by an endless desert.

"Damn it, what's going on? Could this be an illusion?" Su Fang guessed.

He immediately inspected his surroundings.

Yet no matter how Su Fang investigated, the environment around him felt extraordinarily real.

It was vastly different from the illusions he remembered.

"Could this be a secret realm?"

Su Fang guessed again, unable to make heads or tails of it.

But since he was here, he might as well settle in.

Whether it was an illusion or a real secret realm, since he had come, he would uncover its secrets.

Having made up his mind, Su Fang casually picked a direction and started forward.

"Rustle, rustle, rustle..."

Violent sand and dust lashed against Su Fang's face, stinging painfully and feeling utterly real.

However, after Su Fang had walked for roughly an hour.

The desert before him suddenly began to change.

Endless earthfire erupted from beneath Su Fang's feet!

In the blink of an eye, the barren desert became a scorching lava basin!

"Damn it!"

Seeing lava and blazing fire suddenly surge up from underground, Su Fang cursed.

Only then did he realize that he had most likely fallen into an unfathomably profound illusion formation.

Otherwise, there was no way to explain how the environment before him had changed in an instant.

"What kind of illusion formation is this? It's actually this powerful?" Su Fang exclaimed.

At the same time, his mind rapidly recalled everything he knew about formations.

"With one step, one knows spring and autumn; with one formation, one severs eternity."

"Could this be the illusion formation left behind by that former formation supreme of the Clear Profound Sect?"

Ye Han guessed inwardly.

At the same time, in order to verify his conjecture.

He continued walking through the lava basin as though he saw nothing.

And so, another hour passed.

The endless lava and earthfire around him all went out in an instant.

What swept in afterward was snow that filled the sky, and the entire world instantly became an icy snowfield.

"As expected!"

"It really is the handiwork left behind by that formation supreme."

Su Fang confirmed the thought in his heart.

Speaking of that formation supreme, an existence hailed as the greatest formation master of all time.

Su Fang felt solemn reverence from the bottom of his heart.

His name was Xuanjizi. During the ancient era, he had been an extraordinary figure known to everyone under heaven.

He was proficient in every path of formations and had personally created the pseudo-divine formation tome, [Sixty-Four Heavenly Evolution Formations].

Although his cultivation had only reached the Martial Saint realm, it was said that with all his strength devoted to setting up formations, he could even contend against a Martial God.

Therefore, while he lived, the Clear Profound Sect had never needed to worry about the safety of its mountain gate.

As long as he was there, no matter how many enemies came, they were merely delivering themselves onto the chopping block.

And at this moment, Su Fang had fallen into the illusion formation left behind by such a terrifying figure.

He did not know whether he should rejoice or worry...

He rejoiced because this underground palace was connected to Xuanjizi, so its reward was surely extraordinary!

What worried him was that he had absolutely no ability to break an illusion formation laid down by Xuanjizi.

If he could not break the formation, then forget the reward—he might even lose his life.

Thinking of this, Su Fang felt rather depressed.

He simply could not be bothered struggling anymore. He sat down directly and waited for his system's comprehension attempts to refresh before trying to break the formation again.

After all, within the illusion formation left behind by Xuanjizi, if one did not understand its workings and simply wandered around blindly, one would only sink deeper and deeper.

While Su Fang waited.

Elsewhere, Jiang Chen, who had entered the underground palace before Su Fang, had also fallen into the same predicament.

"Damn it! Why can't I get out of this cursed place?"

Jiang Chen threw back his head and roared angrily.

Although he held the key to opening the underground palace in his hand—that mysterious tortoiseshell.

After he fell into the illusion formation.

The mysterious tortoiseshell completely lost all its functions and no longer offered even the slightest guidance. Thus, he sank deeper and deeper into the illusion formation. With only his meager aptitude for formations, there was simply no possibility of escaping it.

Time passed bit by bit.

Suddenly, a pleasant notification sounded beside Su Fang's ear.

"Comprehension attempts have refreshed! Current comprehension attempts: 1."

Seeing that his comprehension attempt had refreshed, Su Fang immediately chose to comprehend the illusion formation before him.

[One of the Sixty-Four Heavenly Evolution Formations: Four Symbols Illusion Formation] could evolve the four symbols of heaven and earth, trapping those who entered within forever. Would you like to comprehend it?

"Yes."

Su Fang immediately chose to comprehend it.

Then, over the endless snowfield before him, threads of golden light emerged one after another, analyzing the profound mysteries of the Four Symbols Illusion Formation...

And Su Fang immersed himself in that ocean of formation knowledge, unable to pull himself free.

After a long while.

The notification in his mind rang out again, finally startling Su Fang awake.

"Successfully comprehended [One of the Sixty-Four Heavenly Evolution Formations: Four Symbols Illusion Formation]."

After successfully comprehending the formation, Su Fang looked once more at the snowfield before him, and not the slightest confusion remained in his eyes.

He then began walking across the snowfield with strange steps, his figure shifting unpredictably...

Very soon, the scenery before him began changing rapidly.

First, it returned to the appearance of the lava basin, then transformed back into a desert.

Until at last, Su Fang completely escaped the illusion formation and appeared once more inside the underground palace.

"Whew, I finally got out." Su Fang let out a sigh of relief.

Then he began exploring the underground palace...

This underground palace was neither large nor small. Because it had existed for far too long, most of its structures had already fallen into ruin.

Other than the Four Symbols Illusion Formation Su Fang had encountered upon entering, there seemed to be no other traps.

Su Fang found this quite unexpected.

But he did not dwell on it. After all, fewer traps were a good thing for him.

He truly did not want to experience another formation on the level of the Four Symbols Illusion Formation.

He feared that if he was not careful and fell into some killing formation, he would be finished on the spot.

After proceeding cautiously for quite some time.

Su Fang finally arrived at the deepest part of the underground palace. What met his eyes was an enormous chessboard.

At the far end of the chessboard, a small array disk floated above a stone platform.

The moment Su Fang saw that array disk, he became wildly excited.

If his guess was correct, that array disk was very likely Xuanjizi's natal treasure—the [Heavenly Evolution Array Disk].

And what happened next indeed confirmed Su Fang's guess.

The moment he approached the enormous chessboard, the phantom of an old man appeared before him...

"Eons pass in haste; seas turn to mulberry fields. I know not what autumn this autumn is."

"Fated one, if you can break this old Daoist's Life-and-Death Chessboard, you may take the treasures as you please."

As the words fell.

The old man's phantom slowly faded away...

On the other side, after hearing the old man's words, Su Fang instead became cautious.

"Life-and-Death Chessboard?"

"I've never heard of it."

Su Fang muttered to himself.
