The old face looked at the vine that was more than a foot thick, and there was a look of unbearability in his eyes.

It knew that if it took the vine itself, its descendants would be in a half-dead state even if they didn't die, and the tree would not survive without roots.

After a moment of silence, the old face turned to look at Qiao Yuan, showing a pleading look, and said slowly.

"Master, the old slave wants to give it a trace of vitality from the natal tree spirit, and hopes that the master will fulfill it. ”

Qiao Yuan naturally knew that this demon tree had lost this vine, and it was probably difficult to survive, so without hesitation, he nodded.

The old man's face showed joy, and he hurriedly thanked him, and then a wisp of green tobacco with the thickness of a finger floated from the natal tree spirit towards the dirt bag.

"Cangliao, use this vitality to maintain a deep sleep, waiting for the day when the ancestor returns. ”

After the green tobacco was all melted into the dirt bag, Cang Tai slowly spoke.

There was no response from the dirt bag, and it was obvious that the demon tree was already extremely weak after losing the vine, but the white roots on the surface of the dirt bag were rapidly shrinking inward.

In an instant, all the countless roots shrank into the inside of the dirt bag, and there was no longer a single one to be seen outside.

The old face breathed a sigh of relief when it saw this scene, and then it slowly dissipated, turning into wisps of smoke and merging into the natal tree spirit.

Qiao Yuan knew that the demon tree had fallen into a deep sleep, and with a wave of his hand, he put the thick vine into the space bead, and then when he was about to take the natal tree spirit away, Cang Tai spoke again.

"Master, there is another place in the depths of this lake, which should be the center of the Great Sealing Array, if the master is interested, you can go and feel it. ”

"Oh, let's go check it out. ”

Qiao Yuan's eyes flashed with a strange light, and he spoke softly.

He had previously known from the formation record that the remnant formation here should be an ancient formation, and he wanted to study it, but unfortunately this formation was too complicated, and with his formation attainments, he had studied it for several days without a clue.

Qiao Yuan grabbed the natal tree spirit with his right hand, and under the guidance of Cangtai, he headed towards the deepest part of the lake.

The deepest part of the bottom of the lake was not on the island in the middle of the lake, but in a location in the eastern part of the lake, where there was a dark pothole, but it was covered by a large number of white bones and dead roots, and Qiao Yuan had not noticed it before.

Qiao Yuan raised his hand and waved, and the spiritual power surged between the waves, and those white bones were swept to the side, revealing the criss-crossing roots.

Qiao Yuan took out a large sword spirit weapon and slashed at the roots of those trees, and after a while, a dark pit the size of five zhang appeared in front of his eyes.

As soon as his divine sense looked inward, Qiao Yuan felt a faint fluctuation of formations, and under the interference of these formation fluctuations, it was difficult for Qiao Yuan to detect what was in the deepest part of the pit.

"Master, in fact, the old slave has not been down here, but the old slave has calculated that the formation center is very likely to be under this hole. ”

Just as Qiao Yuan hesitated, Cang Tai's slightly embarrassed words came into his ears.

"Your calculation shouldn't be wrong, but I don't know what else is under this hole, except for the formation center?"

Qiao Yuan's eyes showed a strange glow, staring at the dark hole, and said softly.

With that, he looked resolute, and leaned down towards the bottom of the pit, and as soon as he went down, he found a huge stream of water rushing from below, as if the pit was a huge spring.

Qiao Yuan used his spiritual power to form a layer of light curtain around his body, isolating those water streams, and sinking down nearly a hundred zhang, Qiao Yuan found that there was a fork in the hole.

One leads to the lower left and the other leads to the lower right, and Qiao Yuan chose the passage to the lower right without the slightest hesitation.

Because he noticed that the passage on the lower right was sealed by a layer of formation light curtain, and at the same time, the water flow was also cut off by the light curtain.

The passage on the lower left did not have the slightest fluctuation of the formation, only the turbulent water gushed out from the passage, and it was obvious that the passage on the lower left led to an underground river.

After Qiao Yuan entered the passage on the lower right, he passed through the formation light curtain without the slightest effort, obviously the light curtain was just blocking the flow of water.

As Qiao Yuan went down, his vision widened, and although the pit was pitch black, he only needed to condense his eyes with spiritual power, and he could still see everything around him.

It wasn't until he had walked down a hundred feet that Qiao Yuan reached the bottom of the hole.

At the very bottom, it looks like a cave rather than a cavern, because the surrounding walls are a layer of black rock, and no earth layer is visible.

The area is fifty zhang in size, and there is nothing but an altar in the center that is ten zhang in size.

Qiao Yuan landed on the ground and glanced around, for some reason, as soon as he came here, he felt a strange feeling in his heart.

It was as if a pair of invisible eyes were staring at him, but he looked around and saw nothing but the altar.

"Master, be careful, this place is a little weird. ”

At this time, Cangtai's words suddenly sounded in Qiao Yuan's heart.

As soon as Qiao Yuan heard this, his expression became more vigilant, since Mrs. Cang had a bad feeling, then the strange feeling in his heart was naturally not groundless.

Qiao Yuan stood there for a long time, never approaching the altar, but with a look of vigilance in his eyes, his divine sense swept around him over and over again.

It wasn't until after scanning the surroundings several times that Qiao Yuan put his gaze and divine sense on the altar.

It was a square altar divided into three tiers, with a stone staircase of twenty-seven steps leading to the top of the altar in the middle of the altar.

On the four stone walls of the altar, Qiao Yuan saw that a relief was engraved on each side.

On the stone wall directly opposite him was an ape with smart eyes and looking up at the sky, while on the left and right stone walls were a goldfish and an eagle, as for its back, Qiao Yuan saw with his divine sense that it was a big python coiled in a circle.

These four reliefs, all carved lifelike, especially their eyes are bright, looking extremely smart.

Qiao Yuan stayed on the ape relief in front of him, and his eyes showed a strange light.

When he saw this ape for the first time, he didn't think anything of it, but when he saw it for the second and third times, he felt that this ape was somewhat familiar, as if he had seen it somewhere.

"Master, the old slave remembers that this ape is one of the man's spirit animals, and it seems to be called ...... Blue-eyed ape. ”

Just as Qiao Yuan was thinking, Cangtai's words came into Qiao Yuan's mind again.

Qiao Yuan didn't speak, but stared at the ape relief for a long time, and then he walked in other directions, looking at the other three reliefs in the distance.

It wasn't until Qiao Yuan was very sure that there was nothing abnormal that he slowly walked towards the altar steps.

But even so, the strange feeling in Qiao Yuan's heart still existed, so his whole body spiritual power flowed, and once anything happened, he would withdraw from this place as soon as possible.

Step by step, Qiao Yuan finally stepped on the altar steps, and the moment he stepped on the steps, Qiao Yuan clearly felt a powerful formation fluctuation permeating the altar.

After taking three steps, Qiao Yuan stopped, unwilling to continue moving forward, because that powerful formation fluctuation would not only give Qiao Yuan a huge pressure, but also gradually suppress his cultivation.

"Well, let's feel here first. ”

Qiao Yuan muttered in a low voice, and then he raised his hand to arrange many guards and prohibitions around him, and explained that Cang Tai carefully paid attention to the situation around him, and then closed his eyes and carefully felt the fluctuation of the formation.

The fluctuation of the formation on this altar is like a big net, intricate, and as soon as Qiao Yuan touches it, he only feels a headache.

If he wanted to sort out these intricate formation fluctuations, I am afraid that he would have to carry out extremely long calculations and deductions, and there could be no mistakes.

"Let's send a message to Miss Qu and Lu Nan first, so as not to worry them. ”

Qiao Yuan secretly said in his heart, thinking of this, he waved his hand and took out a jade slip, and gave a brief explanation of the situation here.

Then he summoned Bai Yue and asked it to send this jade slip to Qu Yunwei's hands.

Seeing Bai Yue leave here, Qiao Yuan slowly closed his eyes, completely dissipated almost all the distracting thoughts in his heart, and began to study the formation fluctuations.

However, he still left a trace of divine thought, if Cang Tai found something abnormal, that trace of divine thought would immediately trigger the space bead and include Qiao Yuan and the natal tree spirit in it, so that Qiao Yuan would dare to study the formation on this altar with confidence.

Time passed slowly, and Qiao Yuan entered the state of contemplation in a silent environment in only one hour.

In this state, he would hardly be able to make mistakes in his calculations, which would greatly improve the efficiency of his research formations.

Cang Tai was extremely shocked when she saw Qiao Yuan enter the Sinking Heart Realm, it didn't expect Qiao Yuan to enter the Sinking Heart Realm, and it only took one hour to enter the state.

And with its insight, it can naturally be seen that Qiao Yuan is very skilled in grasping this state, rather than relying on luck to enter like others.

Ten hours later, Qiao Yuan slowly opened his eyes, and there was a bright light in his eyes, and then he stood up directly and walked towards the top of the altar.

This time, Qiao Yuan felt that the pressure suddenly decreased several times, and at the same time, he no longer suppressed his cultivation.

One step, two steps, Qiao Yuan walked directly from the third step to the ninth step.

The altar is divided into three levels, and between the ninth and tenth steps, there is a platform, which is also the top of the first level.

Qiao Yuan stepped onto the top of this first layer and sat down cross-legged.

"Although this array only has the effect of sealing, it is extremely powerful, according to my calculations, this array has existed for at least three thousand years, and this formation also contains a lot of lost formation knowledge, if I can control it all, my formation attainment will definitely be able to take a big step forward. ”

Qiao Yuan muttered in a low voice, and a hint of excitement flashed in his eyes after he finished speaking, and then he quickly closed his eyes and studied it again.

And after Qiao Yuan closed his eyes, the ape relief on the stone wall of the altar, its smart eyes actually flashed a trace of faint green light.

This faint green glow flashed away, and Cang Tai didn't notice it in the slightest, and as for Bai Yue, who came back early that morning and was lying under the altar, he didn't notice it.
