Behind the barrier, there is a sinkhole that seems to be hundreds of miles deep, and the pillars of water blue air that seem to be formed by spiritual energy rise from the endless bottom of the sea, floating in various colors, or orange, or yellow, or dead gray, or gray-white, and the surface of the sinkhole has countless cracks, deep or shallow, wide or narrow.

But what really shocked the three of them was that in the center of the heavenly pit, there seemed to be a phantom of a palace, this palace was inserted into the water, and the phantom was rippling in the water waves, like a virtual reality, seemingly close in front of him, as if he was far away in the sky.

"Seems a little like it?" Wei Zhen and Yun Si said speechlessly almost at the same time, what they wanted to say was that before entering the mountain passage, the sky was changing, and there was once a magnificent exquisite palace on the top of the peaks.

Just when the two of them were thinking about it, a green light rose up from the virtual shadow of the palace, this green light was not very big, even if it was separated from a very long distance, it seemed to flash in front of them, it looked extremely pure at a glance, without a trace of flaws, and there were wisps of inexplicable fluctuations from the green mang, which provoked people's heartstrings.

"Is there really a spiritual root here?" Yun Si stared blankly at the sky, and there was a little intoxication in his clear eyes, although he knew very well that it was just a projection of the spiritual root.

This green light slowly rose like a firework meteor, and then slowly dissipated, a radius of thousands of miles, I don't know how many pairs of eyes were instantly attracted, and these people rushed in this direction like crazy.

"We have to seize the opportunity!" Wei Zhen was also moved at this time.

But before he could finish speaking, a second yellow light and a third red light rose in that palace one after another...... In a moment, dozens of rays of various colors actually rose.

"What's going on? As far as I know, there are only seven spiritual roots of heaven and earth, so what do the last three represent?" Yun Si was a little dumbfounded.

"Don't be stunned, just go and see. Mu Ziyin urged the two of them.

The three of them crossed the reef barrier together, and rushed towards the upside-down palace at full speed, but Xiao Hei Hei ran in front of the three of them in a puff of smoke.

"Be careful!" Yun Si suddenly swung the jade pen, and a fuzzy glyph flew out, slashing and killing a seven-section sea centipede that attacked Mu Ziyin's back.

Soon after crossing the barrier, the three of them felt a lot of pressure, the number of sea beasts suddenly increased, and they were all around level nine, and some seemed to have almost reached level ten, according to Yun Si's guess, there seemed to be a certain rule power in the pillar of Babel that suppressed the breakthrough of these sea beasts.

In addition, there are resentful spirits in the sea water from time to time, but fortunately, Wei Zhen's black stick and Yun Si's "Palm Shengyuan" spirit skill have a restraining effect on them.

The three of them rested, and they didn't know how far they had sneaked, but they felt that the distance between them and the palace had not decreased much, and they had harvested several precious herbs along the way, including a third-order "Sleeping Sea Lotus", four "Red Star Fruits", a "Water Cloud Algae", and a second-order "Dragon Whisker Grass", and after killing a shell giant beast, they got a dark bead.

The "Red Star Fruit" is like a thorny ball, fragrant and fragrant, and the medicinal power is only one line worse than the "Golden Spirit Fruit", Wei Zhen took the initiative to let it out this time, and Mu Ziyin and Yun Si divided two equally, in addition, the "Water Cloud Algae" was also collected by Yun Si, and the "Sleeping Sea Lotus" was given to Mu Ziyin. Wei Zhen obtained the second-order "Dragon Whisker Grass", although this wisp of "Dragon Whisker Grass" is only a second-order thing, but it is very good for Wei Zhen, he cultivates the exercises of the Shura clan, and the "Dragon Whisker Grass" is a thing that replenishes qi and blood, which is of great benefit to the body after refining bones and melting blood, and is one of the best treasures to enhance spiritual physique.

That dark bead, he originally wanted to give it to Mu Ziyin, but before entering the Tongtian Pillar, Wen Lan had mentioned that if he could find this thing and bring it back, he should be grateful.

So Wei Zhen still chose to survive.

The three of them continued to kill, and they didn't know how much time had passed, each of them was slightly injured, and the elixir prepared by Wei Zhen was half gone, and Mu Ziyin didn't have many items with him when he disappeared, but Yun Si was also well prepared.

There was no day or night in the pillar, and finally the three of them were a little tired. The three of them discussed and found a crack for a temporary rest.

After resting for two hours in turn, the three of them continued to set off, and at this time, in their thoughts, the phantom of that palace was much more real, as if the distance between them had also been shortened a lot.

Wei Zhen couldn't remember exactly how many resentful spirits the black stick had absorbed, and he felt that the protrusion covered by his thumb was like a small mouth at this time, and it seemed to squirm on its own from time to time, and when he opened his eyes and looked quietly, he didn't see half of the movement. What made him even more suspicious was that he would hear that strange woman's voice in his mind from time to time at this moment, over and over again, always with those six words - "I want my soul to return to my hometown!"

He deliberately looked at Yun Si and Mu Ziyin, but saw that the two of them seemed to be unaware, and they didn't seem to hear any unexpected sounds at all.

The three of them killed the sea beasts and resentful spirits all the way, while collecting the spiritual objects under the sea, the results were very good, according to Mu Ziyin's timing method, calculated by the consumption of spiritual power and replenishment time, the three of them actually killed for seven days and seven nights unconsciously, and the "Yun Ling Pill" carried by Wei Zhen had already been exhausted, and it was all supported by the preparation of Yun Si alone.

On the eighth day, they finally came to the periphery of the exquisite palace.

"It must have had a glorious history, but I don't know how amazing its previous owner was to be able to live in such a palace?" Mu Ziyin sighed.

Not only her, Wei Zhen and Yun Si both seemed to know that such a palace was most likely a woman's residence.

The whole palace is divided into seven floors, each layer of murals carved innumerable, extremely fine and exquisite, although it has gone through endless years, although it has lost the splendor of the past, no longer the beauty of the year, but if you look closely, you will still find that every building is ingenious, natural, can not find the slightest fault.

At this moment, such a palace is obliquely inserted in the deep and endless silent water, the eaves of the palace wall are everywhere revealing a little desolate meaning, the things still exist, the master is gone, and the person who can drive this palace that should stand proudly on the top of the mountains into the bottom of the water, what kind of power and power should it have, it is worth pondering.

Wei Zhen watched for a long time, and a strange thought suddenly appeared in his mind.

"Maybe it's not impossible that the mysterious woman who frequently hears that mysterious voice is the original owner of this palace, but where is her hometown?

Thinking of this, Wei Zhen's body suddenly trembled. If the truth is as he guessed, how terrible must this woman with a dead soul be during her lifetime? Although he could not perceive how long this palace had existed, as long as he guessed a little, it should be at least more than 10,000 years, and what kind of person can make the soul immortal for 10,000 years after death?

"Could it be that inside this Tongtian Pillar, there is really an immortal relic?" he couldn't help but think of what Mu Qinglian had said earlier.

Xiao Hei Hei "squeaked" twice, but he was a little impatient, jumped out of his shoulder, and swam forward quickly.

"We're keeping up with that, too. Wei Zhen said. The three of them did not stay any longer, like three small swimming fish, slowly approaching the palace under the water.

At this moment, the direction of Xiao Hei Hei in front of him suddenly changed, and he actually drilled into a crack on the left side of the ground.

"Little Heihei, come out quickly!" Wei Zhen hurriedly shouted, but no matter how he shouted from behind, Xiao Heihei did not respond.

"This stupid foodie!" Wei Zhen scolded hatefully, he looked at Yun Si and Mu Ziyin, and said helplessly: "You go to the palace first, and I will come when I find it." ”

Linggen is an unavoidable opportunity for anyone, but Wei Zhen here can no longer let go of Xiao Heihei, in his heart, Xiao Heihei has long been as important as his relatives.

"It's better to be together. Yun Si said calmly, but he was not in a hurry to delay the opportunity to seek the spiritual root.

"It can't be so. Wei Zhen waved his hand violently, and the moment his body swam out, he seemed to think of something, and looked back and said, "Yunsi, Miss Mu's safety will be handed over to you!"

"Don't worry, Brother Wei!" Yun Si replied from behind him.

Mu Ziyin had just taken half a step, as if she wanted to follow, but after hesitating for half a minute, Wei Zhen's figure had already disappeared into that crack.

"Let's go too. Yun Si said regretfully. Wei Zhen's intentions, he and Mu Ziyin naturally knew it, and they didn't want to affect the fate of the two for the sake of their own pet beasts.

Less than a moment after the figures of the three of them disappeared, dozens of figures suddenly appeared on the periphery of the palace, which were the first batch of sect disciples who hurried to see the shadow of the spiritual root.

When the first group of people entered the palace, nearly half an hour had passed, and dozens of figures shot out, glanced at each other, and rushed to the palace under the water again.

But there was one person, until everyone walked out of sight, he carefully took out a compass from his arms, rotated the pointer on the compass from time to time, and finally seemed to determine a certain direction, he smiled proudly, and quietly swam into the crack in the ground where Wei Zhen and Xiao Heihei disappeared.

In the cracks, the light was uncertain, and the water became a little turbulent, Wei Zhen lifted his "spiritual eyes", holding the black stick tightly in his hand, while carefully looking at the surrounding environment.

He swam for a while, and saw a black shadow in front of him struggling to move his limbs in the water, walking against the direction of the current, and his little head was still looking back from time to time, it was Xiao Heihei.

Xiao Hei Hei saw that he was the only one who came with him, and a touch of humanized joy flashed inexplicably in his small eyes, and then he swam backwards and returned to Wei Zhen's side in an instant.

"You foodie, what's in here that makes your heart flutter?" Wei Zhen lightly tapped on its head, but there was a warmth in his heart.

Xiao Hei Hei deliberately rolled his eyes, bared his teeth, and continued to lead the way.

"Alas, as long as you're happy!" Wei Zhen followed closely, and said sincerely.
