"Whew!" Sha Pei saw Bai Yi and immediately shouted.

"Shar-rír, long time no see, how are you doing?" Bai Yi was also very happy to see Sharpi.

"It's definitely much better than you, isn't your injury better, what's wrong with that." Shar Pei walked over slowly, the ground was trembling slightly, and now Sha Pei was becoming more and more powerful and heavy.

"As soon as I came out, there was another fight, and I was slightly injured." Bai Yi said indifferently.

After finishing speaking, Bai Yi looked behind Sha Pei, and behind Sha Pei was the real core building of the city. It is better to say that it is one building, but it is better to say that it is three, built in a three-legged way, and the shape is rather peculiar. The three buildings are estimated to be about three hundred meters high, and in the center of the three buildings, at first glance there is nothing. But in Bai Yi's eyes, it could be seen that in the center of the three buildings, in the empty air, the pale black mist was slowly rotating.

Reverse flower pupil!

Bai Yi's reverse flower pupils slowly rotated, and then the scene became clearer. In the center of the three buildings, a black halo with a diameter of more than two hundred meters opened up in the air and was slowly rotating. Through the reflective light curtain, you can see an endless void, and inside it is like a reflection of another building.

This is!

Without Bai Yi asking, Mo Mo had already opened her mouth to explain.

"The three buildings here are built according to the new map of the underworld, which can gather and gather yin energy. Although ordinary people can't see it, in fact, the exit of the underworld is here. Although my kingdom of the underworld is not as good as the legendary kingdom of all the dead, it is also the kingdom of the underworld after all. This is the equivalent of the gate of the underworld, so I have Shar Pei guard it here. Mo Mo explained.

"Is that so?" Bai Yi nodded, then looked at Shar-Pei.

"It turns out that the legendary three-headed dog of hell is a Shar Pei!" Bai Yi looked at Sha Pei seriously for a while, and suddenly said.

"Poof!" Everyone originally thought that Bai Yi would say something, but they didn't expect Bai Yi to say such a sentence, so they couldn't help laughing directly.

"Just laugh at you." Shar Pei didn't feel embarrassed.

Mo Mo awakened the law treasure - the underworld, and Shar Pei himself grew two heads, and then after Mo Mo gave the ability to guard the underworld, he grew a third phantom head, isn't this a three-headed dog. Although this is completely accidental, no matter how you look at it, Shar Pei has become the legendary three-headed dog of hell. After Shar Pei's IQ improved, he also learned a lot of things, and he was very stunned about his identity at first, but then he felt that it was no big deal. In other words, Shar Pei has long been aware of his identity, and now he is just being pulled out by Mo Mo to see the door.

"Haha After Bai Yi laughed, he also stopped.

"Well, why do you want Shar Pei to guard here, I believe it's not just because the gate of the underworld is so simple." Bai Yi looked at Mo Mo.

"Hmm." Mo Mo nodded. "Dad, do you know what will become of pure spirit creatures when they lose their physical restraints?" Mo Mo asked.

"No, I don't know." Bai Yi shook his head.

"Now in the underworld, there are two kinds of creatures. The first, even when dead, retains a physical creature. Second, the physical body has long been destroyed, and only the spirit body remains. The first is my underworld creature who reverses the pattern of life, and is no different from normal life except for living in the underworld. And in the second type, I divide them into growth and non-growth. Mo Mo explained.

"Growth and non-growth."

"Well, that's right. Even pure spirits can continue to grow. Those who are not growth types have basically kept the appearance of entering the underworld when they died. Among the spirits in the underworld, this non-growth type is the most numerous, accounting for more than 90%. According to the recent census data, the weaker the soul before death, the weaker the soul, and most of them are this non-growth type. And before death, the strength is relatively high, and the greater the probability that the soul is a growth type. Mo Mo led a few people into the building.

Two maids came again, and then saluted Bai Yi and the others. Bai Yi keenly noticed that these maids were not real human beings.

"This is the 1.1 version of the mechanical maid developed by Night and Night, which is a test version, although there is not much force, but the basic daily behavior is already competent. Although this place is imperceptible to ordinary people, it is not suitable for ordinary life. And this place is impossible for ordinary people to enter here, so they are allowed to carry out daily maintenance here, and by the way, they also help collect data night and night, and then improve it. Allotia explained to Bai Yi.

"Hmm!" Bai Yi nodded. "Let's continue with the conversation."

"There is nothing to say about a non-growth soul, it is basically the kind of spirit that has no potential. And the growing spirits, Dad, do you know what will become of these spirits after losing the restraint of the physical body? Mo Mo led a few people towards the top of the building, and then stepped into the air.

"I don't know what it looks like?"

"The soul is originally the same as the physical form. However, after death, the shackles of the body are lost, and the changes of the soul gradually become diverse. This kind of change is not instantaneous, but in the past few years, it has been enough for some of them to show clues. Mo Mo said. Several people walked past one of the buildings, then stepped onto the transparent corridor in the air, and then entered the gate of the underworld.

There are not many people in the underworld, but they are in order, and it is clear that Vera has managed it well. A figure on the opposite side floated by holding a document, and immediately found Bai Yi and them.

"Yo, Bai Yi, long time no see." Helois was the first to say hello. Then he nodded to Mo Mo and Allotia, who he often saw.

"Long time no see." Bai Yi nodded. Bai Yi looked at Herois, when Herois died, he was only at the level of LV1-2, but now, there is actually LV2. It's slow, but it's growing, and it's better than standing still.

"Are you here to inspect the underworld?"

"Probably."

"The underworld has changed a lot recently, you are busy yourself, I have to deal with some things, Vera is a capitalist." Helois complained a lot, but she didn't complain. The development of the underworld is indeed so orderly under the auspices of Vera.

"Hmm." Bai Yi nodded.

After Helois left, the group continued to walk towards the other side of the underworld. On a suspended platform, Bai Yi and the others looked at the sea that had initially formed below. The black aura and the currents inhaled from the outside world tumbled underneath, and inside, it seemed that some fierce beast was hidden.

"This is what I call the Styx, and last year I went to the ocean and absorbed a lot of seawater." Mo Mo said proudly.

"I can't see it, and I don't see it falling." Bai Yi teased.

"Actually, it still absorbs a lot, but the sea level is falling or something, and there really isn't so much seawater." Mo Mo immediately lowered her head. Bai Yi laughed.

Before he could laugh for long, Bai Yi soon saw what the so-called clues meant. In the Stygian Sea below, many fierce monsters loomed. These monsters still retain some of their human form, but they are completely unable to describe them as human souls. And some of the guys who have changed the most have completely changed into alien forms, and they look very vicious.

"What are these?"

"It's like the physical changes that occur when the active cells fuse the genes of other organisms." Mo Mo said, and then immediately added.

"But no!"

"It's just likeness, the change of the soul has nothing to do with the original body, and there is no law at all about what it can grow into. This change should have something to do with the nature of their own souls, and perhaps, with their sense of self, but I don't know very well now. But one thing is for sure, this is dirty growth. Mo Mo said.

"Filth grows?"

"Well, they still have some of their sanity now, but the more they change, the more they seem to be covered by something, and all that is left is pure beastly instinct." Mo Mo said. At this time, in the underworld void in the distance, a huge creature like a sea snake suddenly jumped out and devoured a large number of mayfly spirits in the air.

"There is no reason!"

"It should be said that it was covered by something." Mo Mo nodded.

"Dad remember the original Soul Tree, when Aunt May Vis said that the Soul Tree has the ability to purify the soul. But we don't know what the hell is going on, but now, it's finally clear. Mo Mo took out a piece of the heart of the Soul Liberation Tree.

"In the growth of the spirit, the first is this kind of filthy growth, although it is gradually getting stronger, but at the same time as it becomes stronger, the original reason is gradually obscured, as if it is tainted by something. The second type is that they were purified by the Soul Liberation Tree and are still growing, but their souls still maintain the type they had before they were alive, and they will not lose their sanity. Like Teacher Vera, like Mayvis and Aunt Helois. Mo Mo explained.

"The Soul Liberation Tree, does it actually have such a powerful force?"

"Well, not only that, but I've also tried that even the non-growth spirit will become a growth type when purified, albeit very slowly, but as if the essence has been changed." Mo Mo nodded.
