Dong Yuanyuan helped the seriously injured Wu Aotian to slowly go inside, crossed the huge beast of death, and came to the side of the deep pool that was still covered with a thick layer of ice.

Although there is a thick layer of ice, but it can't hide the rich aura at all, Wu Aotian felt the thick aura fluctuations, his heart was happy, and he turned his head to Dong Yuanyuan who was holding him and said, "Okay, let's heal here." ”

Dong Yuanyuan put down Wu Aotian, looked at the deep pool with a thick layer of white ice, and took a deep breath, as if he was feeling the obvious aura fluctuations in the air: "It's such a big Lingquan Pond, I don't know how deep it is, we don't need to look for other Lingquan Ponds." ”

Wu Aotian smiled, suddenly remembered something, and said, "By the way, we have opened the belly of the mountain, so will the spiritual energy fluctuations here spread to the outside, and will it attract other spiritual cultivators?"

Dong Yuanyuan frowned and said, "What you said is right, this is a problem, wait for me to deal with it." ”

Dong Yuanyuan left quickly, didn't have much time to come back, and made an OK gesture towards Wu Aotian: "That's it, I used a spiritual weapon that can cover the fluctuations of the aura, sealed the entrance of the cave, and covered the entrance of the cave, although it can't completely cover up the fluctuations of the aura here, but it has become extremely weak, plus I hid the entrance of the cave, I don't think anyone will find out anymore." ”

Wu Aotian breathed a sigh of relief: "That's good, otherwise we killed this fierce beast by fighting to the death, but others robbed us of the fruits of our labor, then wouldn't we have died." ”

Dong Yuanyuan opened his arms, as if he wanted to embrace this huge deep pool, with a happy face: "With this Lingquan Pool, I will definitely be able to reach a high-level spirit master, and even break through the bottleneck and enter the earth spirit!"

Wu Aotian heard Dong Yuanyuan say this, his heart couldn't help but move, because at this time Wu Aotian still had three purple spirit pills on his body, if this Dong Yuanyuan really reached the bottleneck, then he might be able to give her one to help her enter the realm of the earth spirit, although the earth spirit is not very useful with the help of the aura of this spiritual spring pool, but this spiritual spring pool is extremely huge, and the intensity of the spiritual energy in it is far greater than any spiritual spring pool encountered before, even if it is an earth spirit, I am afraid that the cultivation will also make great progress.

What's more, the spiritual spring of this Western Styx Mountain Range only appears once every fifty years, only lasts for one year, and when it expires, it will all disappear, this year's time, if you don't hurry up, if you want to next time, it will be fifty years later, although the life of a spiritual practitioner is already quite long, and with the growth of strength, the life will be extended, but in fifty years, a lot of things can already happen.

On the other side of the pond, there was a huge passage, and the passage seemed to be a little strange, it was a little inclined downward, which made Wu Aotian couldn't help but suspect that this huge cave in the belly of the mountain led to the underground.

Although he had the heart to investigate, Wu Aotian was still seriously injured at this time, so for the sake of safety, it was better to heal his injuries first.

The aura in this pool of water is incomparably sufficient, and the speed of Wu Aotian's healing is much faster, and the Eight Desolations Gathering Spirit Ding is like a sea whale constantly sucking the seawater, and the aura of the Eight Desolations Gathering Spirit Ding quickly became extremely abundant, and the aura of the flame reached an unprecedented level.

Because the aura in the Eight Desolations Gathering Spirit Ding is abundant, the aura flowing to the Wuao Heavenly Spirit Sea has also become incomparably pure, and the amount and speed have expanded a lot compared to before, after the injury has improved to a certain extent, Wu Aotian took the Bi Ling Pill, under the dual effect of the Bi Ling Pill and the Eight Desolations Gathering Spirit Ding, the speed of Wu Ao Tian Ling Hai has widened a lot faster.

Wu Aotian had about forty or so Biling Pills on his body, and the rest of him flew Leng Feng and Mo Yu, and at this time of cultivation, Wu Aotian was not stingy, and took out half of it to Dong Yuanyuan.

Dong Yuanyuan watched Wu Aotian take out the Biling Pill, but he was a little surprised, and said with a smile: "You have a lot of good things on you, refining the Biling Pill seems to require stone stalactite spiritual liquid...... It's very rare, and it's not easy for you to find it. ”

Wu Aotian smiled and said: "It's just luck for a while, I almost died, but fortunately, I didn't die, and I still have gains." ”

Dong Yuanyuan didn't have a polite relationship with Wu Aotian, took the Biling Pill handed over by Wu Aotian, and said with a smile: "With these Biling Pills, my chances of success will be higher." ”

Ten days later, Wu Aotian's meridian injuries had been completely healed, and the curiosity in his heart could no longer be suppressed.

"Dong Yuanyuan, why don't we go explore the inside of that cave?"

Dong Yuanyuan is obviously not a peaceful master, he has long been eager to try, but Wu Aotian has been healing, Dong Yuanyuan can only press the curiosity in his heart, waiting for Wu Aotian, and at the same time he is also working hard to cultivate.

"Okay, okay, I've been waiting for you. ”

Wu Aotian looked at Dong Yuanyuan, whose eyes were shining with excitement, and thought of something, but suddenly changed his mind: "Well, otherwise, in this way, you also know that I can restrain my breath, I will go to the front, you will go to the back, so that if there is something wrong, I can also return in time......"

Dong Yuanyuan nodded without hesitation and said: "Well, yes, don't say it, your method of constricting your aura is really wonderful, after you restrain your aura, I can't feel your existence at all......"

Wu Aotian shook his head and said: "This is only effective for a certain amount of poor strength, if it is an earth spirit powerhouse, it is impossible to completely hide it, but it is even more difficult to be discovered......"

Dong Yuanyuan's eyes lit up: "Can you teach me?"

Wu Aotian smiled bitterly: "This method relies on some things, and these things are unique to me, so I can't teach you, even if I teach you, I can't use it." ”

Dong Yuanyuan sighed, but there was no disappointed expression, and there was not the slightest doubt on her face, obviously she believed that what Wu Aotian said was true.

Wu Aotian and the two walked along the edge of the deep pool to the opposite bank, Wu Aotian restrained his breath and controlled the light system magic crystal to float far in front of him, while Wu Aotian himself was hidden in the darkness and touched towards the front of the passage, and Dong Yuanyuan followed Wu Aotian for a long distance.

The cave was huge and inclined, and Wu Aotian walked all the way, but found that the cave was all the way to the underground, and there was no life in the cave, only some scattered plants.

Just walked forward about a few kilometers so carefully and cautiously, with his senses, Wu Aotian estimated that he was now thousands of meters underground, Wu Aotian had some strange feelings in his heart, this place seemed to be really peculiar.

Wu Aotian carefully looked at the cliffs of the cave, but there was more and more a sense of wrongness, that is, these cliffs did not seem to be naturally formed, but artificially formed, because the size of this passage is basically the same, and the appearance of the cliff is also similar, if it is said that it is naturally formed for a distance, it may still be possible, but it is too difficult to form such a passage of several kilometers.

It's just that even if this place is really artificial, it must be a very distant time, and it can be seen from the traces of weathering and other traces on those cliffs, but it is impossible to judge how long it has been.

The sloping downward passage suddenly became flat, and the originally uneven ground was flattened all of a sudden, Wu Aotian took a closer look and was surprised again, because the ground was already a flat stone slab.

Although this slate is not a precious jade, nor is it a precious stone, but it is one of the hardest rocks, even if the sword is split on it, it will only emerge a few sparks at most, but on the ground, these slabs are neatly spread on it, like a knife cutting tofu, neatly and neatly.

Stepping on that stone slab, Wu Aotian's heart was a little aggravated, although he hadn't touched anything yet, but he had a strong premonition, in this underground, he was afraid that he would find something very shocking.

No one would be bored to carve out a huge hole in the belly of a mountain for several kilometers, and no one would have enough to hold on, and would cut the rock neatly and lay it on the ground, all of which clearly showed that there was something different in the ground, and that it was now going to show up before him.

Suddenly, a ray of light appeared in the darkness ahead, and it seemed to be a light magic crystal, quietly emitting light in the darkness.

Wu Aotian walked forward slowly, and the light in front of him was getting brighter and brighter, one, two, three......

Dozens, hundreds, hundreds of light system magic crystals, like small crystal dots, appeared in front of Wu Aotian's eyes, Wu Aotian looked at the large piece of bright light that appeared in front of him, as well as the man-made buildings under the bright light, and finally couldn't help but let out a long breath.

Dong Yuanyuan, who was following from a distance, also noticed something unusual, and in shock, he gave up hiding his body and came to Wu Aotian's side, looking at the underground world illuminated by the light system magic crystal with Wu Aotian, his eyes were full of shock.

A large stone staircase slowly spreads into the distance, and on both sides of this stone staircase, there are light system magic crystals illuminating, like street lamps.

At the far end of the stone staircase, there is a palace-like building, which is very tall, at least tens of meters high, standing abruptly in this underground stone cave, which looks extremely strange.

"What the hell is going on, who built this place?" Dong Yuanyuan also exhaled slowly, turned his head to look at Wu Aotian in shock, and asked in his heart: "Is there still a human habitation here?"

Wu Aotian was also puzzled, thinking about the huge spiritual spring pool above himself and the others, as well as the fierce demonic beast, the stretching tunnel, and the man-made palace, Wu Aotian shook his head and said: "I don't know, let's go, let's go and see what it is, to see if it's a curse or a blessing." ”
