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

I saw the flow of light and shadow.

In an instant, the surrounding scenery suddenly changed.

When he comes back to his senses, how can there be any underground palace?

As far as the eye can see, there is a boundless desert all around.

"I'll go, what's going on? Is it a fantasy? The Soviet side speculated.

Then he looked around.

However, no matter how the Soviet side probed, the surrounding environment gave the Soviet side an extremely real feeling.

It was very different from the illusion he remembered.

"Is it a secret realm?"

The Soviet side guessed again, and he was a little puzzled in his heart.

But if it comes, it will be safe.

Whether it's a fantasy or a real secret realm, since you're here, let's unlock the secrets here.

After the Soviet side made up its mind, it randomly identified a direction and began to move forward.

"Sand, Sand, Sand......"

The fierce sand and dust, scraping on Su Fang's face, made people feel so real.

However, almost an hour after the Soviet side left.

Suddenly, the desert in front of me began to change dramatically.

I saw an endless earth fire, suddenly emerging from the feet of the Soviet side!

In an instant, the originally barren desert immediately turned into a scorching magma basin!

"Damn it!"

Looking at the magma fire that suddenly emerged from the ground, Su Fang scolded angrily.

At this moment, he suddenly realized that he was likely to fall into an unfathomable phantom array.

Otherwise, it is impossible to explain the imagination of the environment in front of you that changes suddenly.

"What kind of phantom array is this? How powerful is it? Su Fang exclaimed.

At the same time, my mind began to quickly recall the knowledge related to the formation.

"One step to know the spring and autumn, a burst and eternal."

"Could it be the Phantom Array left by the Formation Supreme who was close to the Qing Xuanzong?"

Ye Han guessed in his heart.

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

He continued to walk in the magma basin in oblivion.

And just like that, another hour passed.

The endless magma fires around them were all extinguished in an instant.

What followed was a flurry of snow, and the whole world instantly turned into an ice and snow field.

"Sure enough!"

"It's really the handwriting left by the Formation Supreme."

The Soviet side affirmed what it had in mind.

Speaking of that formation supreme, he is known as the existence of the first person in ancient and modern formations.

In the bottom of Su Fang's heart, he was also in awe.

His name is Xuanjizi, and in ancient times, he was a transcendent figure that everyone knew and everyone knew.

He is proficient in various formations, and has created his own pseudo-god-level formation treasure book [Tianyan Sixty-four Formations].

Although the cultivation is only in the realm of the Martial Saint, it is said that under the full force of the array, it can even compete with the Martial God.

Therefore, during his lifetime, Qing Xuanzong never worried about the safety of the mountain gate.

As long as he is there, no matter how many enemies come, it will be the fate of delivering food.

And at this moment, the Soviet side is trapped in the phantom array left behind by such a terrifying figure.

I don't know whether to be happy or worried......

Happily, this dungeon is related to Xuanjizi, and the reward must be very amazing!

The worry is that the phantom array laid by Xuanjizi is not capable of cracking it at all.

If you can't break the formation, let alone the reward, I'm afraid you will have to lose your life.

Thinking of this, the Soviet side was quite depressed.

I didn't bother to struggle, I just sat down, waited for the number of times my system comprehension was refreshed, and then tried to break the formation.

After all, in the phantom array left behind by Xuanjizi, if you don't understand the doorway, you just walk around, and you will only fall deeper and deeper.

And while the Soviet side was waiting.

On the other side, Jiang Chen, who entered the underground palace earlier than Su Fang, was also in the same predicament.

"Damn! Why can't you get out of this hellish place? ”

Jiang Chen roared angrily at the sky.

Although he has the key to open the underground palace in his hand, the mysterious turtle shell.

However, after it fell into the phantom array, the mysterious turtle shell completely lost all its functions and no longer brought the slightest guidance.

In this way, he fell deeper and deeper into the phantom array, and with his meager formation comprehension alone, there was no possibility of getting out of the phantom array at all.

……

Little by little, time passed.

Suddenly, a pleasant prompt sounded in Su Fang's ears.

"The number of comprehensions has been refreshed! Current number of realizations: 1. ”

Seeing that the number of comprehensions had been refreshed, Su Fang immediately chose to comprehend the phantom array in front of him.

[Tianyan Sixty-four Arrays One of the Four Elephant Phantom Arrays] can evolve the four elephants of heaven and earth, trapping those who enter the formation in it forever. Do you comprehend?

"Yes."

The Su side immediately chose to comprehend.

Then, I saw that on the endless snowfield in front of me, golden silk threads emerged, analyzing the mysteries of the four elephant illusion arrays......

And the Soviet side was also immersed in the ocean of knowledge of this formation, so it couldn't extricate itself.

After a long time.

The prompt sound in his head sounded again, and it woke up Su Fang.

"Successfully comprehend [Tianyan Sixty-four Arrays, One of the Four Elephant Phantom Arrays]."

After the success of the Wu Array, Su Fang looked at the snowfield scenery in front of him again, and he was not the slightest confused.

Then he took a strange step and began to walk erratically on the snowy field......

Soon, the scenery in front of me began to change rapidly.

First it reverted to the appearance of a magma basin, and then changed back to the appearance of a desert.

Until the end, Su Fang completely walked out of the phantom array and reappeared in the underground palace.

"Whew, it's finally out." Su Fang breathed a sigh of relief.

After that, he began to explore in the dungeon......

The underground palace here is not big or small, and most of the buildings have long been dilapidated due to the age of existence.

Except for the four-elephant phantom array that the Soviet side experienced when they first entered, there seemed to be no other traps.

In this regard, the Soviet side was also quite surprised.

But he didn't think much about it, after all, there were fewer traps, which was a good thing for him.

A formation of the level of the Four Elephant Phantom Formation, he really didn't want to experience more.

I'm afraid that if I'm not careful, I will fall into a certain killing array, so I will be cool directly.

Cautiously walked away for a while.

Su Fang finally came to the deepest part of the underground palace, and what caught his eye was a huge giant chessboard.

And at the end of the chessboard, on a stone platform, a small array plate is suspended.

Seeing that array, the Soviet side was instantly excited.

If he guessed correctly, it was very likely that the array disk was Xuanjizi's natal magic weapon - [Tianyan Array Disk].

And what happened next did confirm the Soviet speculation.

As soon as he approached the giant chessboard, an old man's remnant appeared in front of him......

"Eternal rush, vicissitudes. I wonder what autumn it is this year? ”

"If you are destined, if you can break the life-and-death chess game of the old way. Treasures can be taken at your disposal. ”

The voice fell.

The remnants of the old man slowly disappeared......

On the other side, after hearing the old man's words, the Soviet side suddenly became cautious.

"A game of life and death?"

"I've never heard of it."

The Soviet side muttered to itself.
