"The man-made underworld, perhaps...... A large number of humans died at once, plus a special pattern. Vera said.

"We all know that the soul of the Tao will dissipate in the natural environment. So can it be considered that a large number of human beings die at one time, and the number of souls exceeds the speed of dissipation in this range, and with the special pattern environment, then the underworld is formed. For example, the special architectural composition here in Wellington, such as the pyramids, such as the terracotta warriors and horses, those who were buried, didn't they die a lot at once. Vera continued.

I have to say that Vera is indeed smart and very clear, but this explanation has made everyone's hearts sink.

Death of a large number of humans!

"Okay, let's not talk about it, we can't try it anyway. Mayvis, let's talk about purification, just now you said that Vera and their souls were defiled, what happened? Bai Yi asked. Bai Yi diverted from this topic, because if he continued to talk, he always felt as if he was touching some kind of forbidden area.

"Purification, that's it!" Mavis began to explain.

"When you first saw the murderous spirits, when they hunted and killed, they were very violent, and they always distorted into all kinds of fierce and strange appearances. In the beginning, although these evil spirits were twisted and changed into those forms, when they were quiet, they would still revert to their human form. However, after that, we found that these fierce spirits gradually deviated from the original human soul form, and really changed to the appearance of monsters, which is filth. Mavis said.

"It's not just the souls, but even the souls of us who still have their own consciousness will change in the same way. I can't say that this change is bad, but I think it's just one of the ways in which pure spirit life evolves. After losing the shackles of **, when pure spirits grow, they don't have to follow the original racial constraints, so they become weird. And those spirits that have become strange have indeed become more powerful, and a small part of them can directly attack reality. Mavis explained.

One of the ways in which spirit life has evolved!

Direct attack on reality!

How to say it, Bai Yi really didn't expect that they would learn so much shocking news here. Don't look at these messages are only a few short sentences, but they can be regarded as top-secret information.

"What about you?"

"Purification and ablation, the power of the Soul Tree. As you can see, the Evil Spirits love this place very much, but they don't dare to get too close to it. The Soul Tree can purify the spirits and keep us in our original life form, so I can now appear to you in human form. However, if you can't control yourself during purification, then it is not purification, but it is directly sucked into the Soul Liberation Tree and dissolved directly. Mavis said.

"Hold yourself, why don't we feel anything?" Vera and Helois asked.

"Because the Soul Tree is dead!" Mavis said sadly, then pointed to the dozens of other mayfly spirits around her. "Look at them, there were hundreds of thousands of souls of all kinds in Wellington at the beginning, and now only a few dozen of us control ourselves, and the rest ......." What happened to the rest, I don't need to go into details.

"Anna!" Bai Yi saw one of the mayfly spirits.

"Yo, I thought you had forgotten about me, and you didn't even say hello." Anna floated over and reproached.

"Where, we are still impressed with you, but we just heard the news and were too involved, so we didn't notice it." Bai Yi hurriedly smiled and apologized. At the beginning, it was the mad ghost Anna who took them to find Yu Han.

"Hmph, I'll trust you." Anna said arrogantly.

"Our purification is not complete, and I still feel different from you." Vera looked at the dozens of mayfly spirits and said.

"Well, of course. When we purify, the Soul Tree is alive. Now that the Soul Liberation Tree is dead, although the ablation ability is gone, the purification ability has also been weakened many times. Anna said, not at all rusty.

"Speaking of which, you take the heart of the tree, otherwise it will definitely be taken by the people of the United Nations." Anna floated in the air.

"Tree Heart?"

"It's the heart of the tree, after the soul release tree dies, not all parts have the ability to purify, only the most central piece of the heart remains, and it is estimated that there is a piece as big as twenty centimeters. By the way, it's best to take some of the other Soul Release Trees with you, looking at the appearance of those people just now, if you don't take it, it is estimated that in the near future, there will be nothing left of this Soul Release Tree. Mavis said in detail.

"Of course." Bai Yi nodded.

"Aunt Mayvis, what about those Soul Eaters?" Mo Mo endured it until now, and saw that other things had basically been said about the same, so he asked this question.

"Butterflies!"

"Like the other spirits, they were absorbed by the Soul Tree. Most of the spirit eaters have become spirits, and those who have not become spirits have all been eliminated, and when there are fewer and fewer spirits, they will have no suitable living environment. Mavis was also very sad when she talked about this problem.

Whether it's the Soul Tree or the Soul Eater, they are all special creatures after Wellington became a ghost town. While they have become special, they no longer adapt to the normal worldly realm.

When Mo Mo heard this, she looked like she wanted to cry but didn't want to cry. If it were an ordinary child, I'm afraid I would have started crying unreasonably, but Mo Mo is different, she has experienced a lot of parting, and knowing that simple crying can't solve any problems. Bai Yi couldn't help but sigh when he saw Mo Mo's appearance, Mo Mo was so young, she had developed this kind of overly strong xìng character, and she didn't know if the Dao was good or bad.

"Cry when you want to." Bai Yi patted Mo Mo's shoulder.

"Little butterflies, they're all dead, Dad, little butterflies, they're gone." Mo Mo threw herself into Bai Yi's arms, grabbed Bai Yi's sleeve, and cried loudly. In fact, Mo Mo is only a little over nine years old now, and many times, Mo Mo is pretending to be strong. At this age, children should cry when they want to, and let adults bear their troubles.

Mo Mo cried very sadly, and the remaining six spirit eaters on Mo Mo's body also flew out and slowly flew around Mo Mo. After crying for a while, Mo Mo sobbed and looked at the six Spirit Eaters, one of which stayed on the tip of Mo Mo's nose and slowly flapped its wings.

Everyone suddenly fell silent, and they all knew that Mo Mo could communicate with spirits and animals, and now Mo Mo must be talking to the Spirit Eater.

"They say I have the breath of the Spirit Eater Butterfly Clan." Mo Mo looked up at Bai Yi.

"They will sleep on you, of course they have the breath of a spirit butterfly." Woolf interjected. However, Bai Yi and the others ignored Woolf's words, but thought carefully about it for a moment.

"That fruit just now!" Everyone looked at each other and said at the same time.

"Probably because of that fruit. After all, it is the fruit of absorbing the growth of all spirits, so I guess there is some connection. However, this is up to you to figure it out for yourself, after all, this fruit is too peculiar to produce, and we don't know what is going on. Bai Yi touched Mo Mo's little head and comforted.

"Did the little butterfly grow in the fruit, did I eat it?"

"This is the way of ignorance." Bai Yi said with a smile.

At this time, not only Bai Yi, but everyone was curious and looking forward to that strange fruit. What is going on with the fruits that grow in this special environment, as well as the breath of the group that those few spirit eaters said? This world, after the spread of living cells, seems to be becoming more and more strange, more and more interesting, and of course more and more dangerous.

After Mo Mo also quieted down, Bai Yi and the others began to take out the heart of the tree according to Mei Weisi's instructions. In addition to the heart of the tree, Bai Yi also took an extra piece of soul release wood about one meter long and one meter wide next to the heart of the tree. Such a piece of Soul Liberation Wood is not worth mentioning compared to the entire Soul Liberation Tree. Bai Yi and they are not greedy, having such a piece of soul release wood is almost enough, and it is not convenient to carry more.

At this time, Bai Yi asked Mo Mo to call out the other souls, which were those LV2 companions who died at the beginning. After a brief explanation, Bai Yi asked them all to purify through the heart of the tree. As for the souls of those ordinary human soldiers that Mo Mo collected, they were not treated so well.

After the purification, they also changed their place of residence. At the beginning, Bai Yi and the others just broke a branch of the Soul Liberation Tree at random, but now that they have such good conditions, of course they need to replace it.

Malvi made a simple pendant for each person with soul-releasing wood, Malvi is a refiner, and his processing and polishing skills are also good, although each pendant is carved from wood, but they are all more jīng beautiful. Everyone took it seriously. Knowing the role of the Soul Release Wood, needless to say, the preciousness of this thing is needless to say, if they die unexpectedly, then the soul can be preserved in the Soul Release Wood. This is also the reason why those people in the outside world attach so much importance to the Soul Release Wood.

Mo Mo has two pendants on her body, one is Bai Yi and their teammates, and the group of companions who entered LV2 at the beginning. Inside a pendant is an ordinary soul.

"Let's go!" Bai Yi took Mo Mo's hand and said.

Hearing Bai Yi's words, a group of people withdrew their gaze and slowly walked outside.

Behind Bai Yi and them was a quiet Wellington. After Bai Yi and the others took the heart of the tree, it seemed that a trace of the dark qi that had gathered behind the most dense place in Wellington also disappeared. The soft sunlight shines down from the sky, and the whole of Wellington seems to reveal the fresh breath of sunshine everywhere. It is this kind of breath, the breath of the normal Anthropocene realm, the environment that countless ordinary people yearn for, but it is the realm of the world that cannot stay after death.
