At this time, the vitality was getting thinner and thinner, Xie Yun was in a hurry, the small universe was still a little full, Xie Yun was running the exercises at full speed, frantically absorbing the vitality.

In the end, the vitality finally dissipated little by little, but Xie Yun's small universe was still a line away from being filled, Xie Yun couldn't help but be disappointed for a while, although it was only one line away, but without these abundant vitality, in this place where the vitality was thin, I am afraid it would take several hours to fill this line.

The spirit body beside Xie Yun saw Xie Yun's puzzled look, only to see it shake its head and think for a while, and then suddenly a large group of transparent insects flew out of its body and flew towards Xie Yun.

The worm easily penetrated Xie Yun and flew out from the other end of Xie Yun's body. Seeing that Xie Yun didn't do anything, the spirit body kept making gestures in front of Xie Yun.

Xie Yun looked at the spirit body suspiciously, the spirit body had become more and more powerful at this time, if it was said that it had only the strength of the Qi refining period when it encountered the spirit body before, then the spirit body at this time had already reached the cultivation of the foundation building stage.

This cultivation speed also surprised Xie Yun, and he asked Immortal Shu, "Immortal Shu, how can this spirit body cultivate so quickly, don't they need to find their own opportunity to break through the foundation building period?"

"That's where these spirits are terrifying. Xianshu replied, "As long as they have enough vitality, they will be able to grow forever and will hardly encounter any bottlenecks, which is very similar to the ghost head in your porcelain vase, but this kind of anti-heaven cultivation speed will make it face a thunderstorm that is dozens of times stronger than ordinary monks during the tribulation period, and many powerful existences of the same kind are stuck at the threshold of the tribulation period and are slashed to ashes by the thunder tribulation." ”

"What if they survive the Tribulation Period?" Xie Yunyou asked.

Xianshu replied: "Throughout the ages, it is almost unheard of for a spirit body that can survive the tribulation period, I think about it, I remember, it seems that there is such a one, in which galaxy? Anyway, after the tribulation period, the spirit will become extremely terrifying, and it is easy to kill people by leapfrogging, but the spirit that has passed the tribulation period was finally besieged by dozens of strong men after sweeping a star field, and the soul was scattered. ”

"Throughout the ages, how young is this? Only one spirit has successfully passed the transitional tribulation period, and this difficulty is too perverted, right?"

"Needless to say, if an inanimate object wants to succeed in cultivation, this is not tolerated by the heavens, and the difficulty is naturally extremely difficult. ”

While Xie Yun sighed for the spirit body again, he saw that the spirit body was constantly gesturing at him, constantly letting the transparent insects fly into his body.

"Is this for me to absorb these little worms?" Xie Yun wondered.

So he tried to absorb a transparent insect into his body, only to feel a stream of pure vitality flowing into the small universe. Seeing that Xie Yun was starting to absorb, the spirit body suddenly showed a happy expression on its face, and a group of small insects pounced towards Xie Yun, as if urging Xie Yun to absorb more.

Since it was the vitality voluntarily sent by the spirit, Xie Yun was also unceremonious, and absorbed all the insects that flew over into his body, and as the vitality formed by the insects continued to replenish, the poor line of vitality in Xie Yun's small universe was finally replenished, and the small universe began to become unstable, showing signs of evolution.

Xie Yun was overjoyed, and hurriedly held his breath, carefully observing the evolution of the small universe.

The small universe quickly expanded, then collapsed, condensed into an infinitesimal singularity, and soon the singularity had a big bang, and the small universe was created in the explosion, and a more vast and infinite space-time appeared in the new small universe.

The original abundant vitality was only half at this time, but the degree of its purity and condensation was even better than before, and in terms of quality, it had completely risen a notch. In the rolling vitality, the terrifying power contained in it made even Xie Yun feel a little frightened.

"Is this the true qi that can only be condensed by a Yuan Infant Cultivator?" Xie Yunxi said, "In this way, I also have the strength of a Yuan Infant Monk in disguise, and I can only protect myself against the Yuan Infant Monk. ”

After the surprise, Xie Yun got up from the ground, behind the stone wall that was blasted open by his own punch, there seemed to be a broader space, I don't know what was inside, it could contain such a majestic vitality.

So after Xie Yun stepped into the stone wall, the spirit body was a little scared, looking around from time to time, but finally followed Xie Yun.

Behind the stone wall, there seems to be a large underground square, and in this dark space, green ghostly fires are everywhere, almost illuminating the vicinity.

And under this forest ghost fire, there are countless bones everywhere.

These bones are stacked on top of each other, and I don't know how thick they are, Xie Yun carefully identifies them, most of them are many unknown creatures, but some of them are human bones, these bones are as colorful as gold and copper, exuding the texture of metal, they can be preserved for such a long time without turning into ashes and dirt, it can be seen that these people and creatures are all peerless powerhouses when they are alive.

And these bones all have fatal wounds on their bodies, and some of them still have signs of struggle.

Xie Yun was shocked: Could it be that these thousands of creatures and humans were all captured and killed here? Isn't this place a huge slaughterhouse?

Xie Yun immediately understood why there was such an abundance of vitality behind this stone wall, it turned out that after these strong men died, the vitality contained in their bodies gradually spread out with the decay of their bodies, filling the square behind this stone wall.

Xie Yun raised his head, only to see that the top of the lower square was also sealed by the boulder, but with the long geological movement, the stone roofs in many places had been squeezed or pulled to deform and crack, Xie Yun suddenly had an idea, could it be that the thin vitality of the world was formed by the vitality exuded by the death of countless peerless powerhouses in this low square overflowing outside the square, right? No wonder the spirits all emerged from this position, maybe this is the place where they were really born.

Xie Yun's mind moved, as if he had found something under the bones, he raised his hand and waved, and an infinite force suddenly lifted a layer of thick bones, revealing the situation underground.

I saw that there were also dense and complex runes engraved on the ground, Xie Yun looked closely, and saw that these runes were all integrated, and there were black dried up on them, almost turning into stone blood remnants, and these remnants could barely be identified as heading in one direction.

Blood Groove!Xie Yun immediately understood the function of these runes.

Xie Yun hurriedly flew up and flew in the direction of the blood trough, flying over the empty square and the dense bones, Xie Yun finally flew to the end of the blood trough.

I saw that this was already the end of a thick stone wall, and the stone wall had collapsed for the most part, and behind the stone wall was completely russet rock. Obviously, when you get here, there is no way out.

In the midst of the russet rock, a dark iron pillar stretched horizontally, and it was so thick that it took almost two people to wrap it around. One end of the iron pillar was in the russet rock, and I don't know where it was heading, and the iron pillar protruded from the rock into a small pool.

The end of those rune blood troughs is also this small pool, obviously after the countless peerless powerhouses here were killed, their blood flowed down the rune blood trough to this small pool, the small pool may have been filled with the blood of these peerless powerhouses back then, but after a long time, the small pool has long been empty, only there are some black traces on the wall and bottom of the pool.

The small pond is used to hold blood, so what is the use of this iron pillar? Xie Yun was puzzled.

Suddenly-

Immortal Shu shouted in Xie Yun's mind: "Hurry up, get out of here!" The voice was frightened and hurried, as if as long as he didn't leave immediately, something terrifying would happen.

Xie Yun was startled by the sound of the immortal book, but he also understood that something must have happened, so he hurriedly flew up and flew towards the exit where he came. The spirit body didn't know why, and looked at Xie Yun suspiciously, but it still followed behind Xie Yun and flew away with Xie Yun.

During the flight, Xie Yun couldn't understand why Xianshu was suddenly so frightened, thinking about it, Xianshu only reacted after seeing the dark iron pillar, he couldn't help but look back at the iron pillar in the blood pool, and faintly saw that the dark iron pillar seemed to move slightly, like a long black tongue in the mouth of an evil ghost.

When he flew out of the underground square and into the crack, the immortal book still kept urging him to go quickly. Xie Yun had to continue to fly until he flew out of the crack, flew onto the surface, and flew far away before the immortal book said that he could stop.

"What is that iron pillar?" As soon as he stopped, Xie Yun couldn't help but ask.

Xianshu asked rhetorically, "Don't you think it's familiar?"

Familiar? Do you mean I've seen it before? Xie Yun racked his brains to search for his memories little by little, and suddenly he finally thought about it, and said incredulously: "The material of that iron pillar seems to be very similar to that Tower of Babel!"

"That's right," Xianshu said in a low voice, "that iron pillar is part of the base of the Tower of Babel, and that place is a sacrificial ground!"

"Sacrificial ground?" Xie Yun thought for a moment, "Could it be—"

Immortal Shu said the following words for Xie Yun: "Those strong people are all used for living sacrifices. Their essence and blood flowed into a pool of blood for the Tower of Babel to suck in. And this kind of lowly sacrificial ground, I'm afraid that in the underground of this world, it is everywhere. ”

"Oh my God!" Xie Yun couldn't help but exclaim, "How many people do you have to sacrifice alive?"

Surprised, Xie Yun thought of something again, and hurriedly said: "There are still many such sacrificial grounds? In this way, as long as the leakage inside is not too serious, maybe there will still be a lot of abundant vitality left like this sacrificial ground, and when I find them, won't it be a big improvement in cultivation? With so many sacrificial grounds and so much vitality, it is difficult to say that I can directly rush to the Mahayana period!"

"Don't enter the sacrificial arena again!" Xianshu flatly refused. (To be continued.) )
