No ordinary cultivator dares to act like this in front of the ancestor Chen Tuan. After all, the following of the name is the word "ancestor". Even the top cultivators in this world would respectfully call him "ancestor" when they see him, because their seniority is there and their cultivation is there. But Li Yifei still did it, and Chen Tuan didn't care.

"There is an underworld!" Chen Tuan said affirmatively, and Li Yifei quickly turned his gaze back and said, "Where is it? Underground?"

"here!"

"Here?" Li Yifei opened his mouth wide, looking disbelief, and soon asked again: "Here? Is this world an underworld?"

"good!"

This subverted Li Yifei's perception. He was a little unacceptable. After a long time, he said, "Why are there people everywhere here?"

"Who said that the underworld is the place where ghosts stay?"

"Uh, right? I can feel it if there are fools!" Li Yifei said.

"Soul is spirit!" Chen Tuan said leisurely.

I went there! Li Yifei seemed to have a door opened. The conversation between the two was casual and not much logic. But now he was stunned for a moment, and then he could think of many things after connecting these things.

Could it be that this world is the legendary underworld on Earth, or it may be the so-called paradise or hell in the Western world? In short, it is the place where people lead to after death?

"If a cultivator is not a cultivator, he will also absorb spiritual energy. As long as it is life, there will be spiritual energy. The higher the spiritual energy, the more spiritual energy it has, the more it will be released after death. Often, after a person dies, spiritual energy will come to this world, which is also the so-called soul and soul. Of course, after ordinary people die, their spiritual intelligence disappears, and they may not be able to persist in coming here. That is, the so-called going to the underworld. Their spiritual intelligence will often slowly dissipate in the moment of death and spread in the world, let alone other animals.":

"So this is the reason for the high spiritual energy in this world?"

"There are more cultivators, so the more spiritual energy they consume, and the more spiritual energy they release after death!" Chen Tuan said.

"But what does it have to do with the underworld? Ancestor, you just said it directly. The boy is really a little confused!"

"Haha!" Chen Tuan smiled loudly, as if he hadn't said so many things for a long time. He took a sip of wine and said, "Since you want to listen, I will start by saying it from the beginning. These things are the ultimate principles between heaven and earth, and you should understand them!"

"Okay!" Li Yifei nodded happily.

"At the beginning, there were two different parts of heaven and earth in the world. One is your earth, which is also the basis of all things. There are countless animals in the world, and humans are just one of them. However, humans are the first to understand the principles of the world, so they can practice, open up themselves, and create their own world. The other is this world, which is not created by practitioners, but has always existed, existed between heaven and earth, and existed in the world."

Li Yifei seemed to be listening to a fantasy, but he did not interrupt Chen Tuan.

"When the people on Earth die, their spiritual energy may disappear, or come to this world. It is called "going to the underworld and waiting for reincarnation. When the cultivator dies, the spiritual energy will dissipate more, and more people will come to this world. Some of them have strong cultivation, so the soul may remain and become evil things. People who have cultivated to the Nascent Soul stage can be considered as becoming their own world and brewing the Nascent Soul. It is also what people often say that having a second life, even if the physical body dies, they can escape their lives. They just need to practice again."

"Here, the beast tribe also has the intelligence and can practice, which is much easier than on the earth. This balance was broken hundreds of years ago. I just heard your story and the changes that have taken place on the earth over the past few hundred years. I also felt a little touched. It seemed that my decision was right. I have been confined to this problem over the years. Was the decision right? For cultivators, the world has a strong spiritual energy and is suitable for cultivation, but if the passage between the two worlds is blocked, it will make people unable to return to their hometown. It also triggered that great battle and the creatures were devastated. I originally wanted to let ordinary people live a good life, but the result was backfired and harmed them!"

"But the earth was saved because of this, but it only made people in this world suffer!"

It may not be saved. People are always selfish and only care about their own interests. After all, people's hearts are separated from their stomachs, and the pollution, wars, and harming others on the earth have never stopped.

In terms of spiritual energy, it seems to be rescued, because Chen Tuan then talked about balance, that is, the way to balance yin and yang. If the practitioners were allowed to continue, then the earth would probably be destroyed. This is not an exaggeration.

As for this world, four-fifths of the top cultivators died after that war. Although they could not destroy the world, because the top cultivators died, the resources they needed to occupy became much smaller. In addition, the world is already full of spiritual energy, and at least it can harm many years.

Li Yifei couldn't help but be happy when he heard this. He told the practitioners that they were here to protect the earth, and then regardless of their life or death. From the past, this was a very moral choice.

Through Chen Tuan's description, Li Yifei thought of a word, which is also a word that can be seen in scientific magazines in recent years! Whether it is China, Europe and the United States, they are all studying this matter. Is there any dark matter? The answer is yes. Through scientific observations and theoretical physics analysis, the existence of dark matter can be concluded, but what exactly is dark matter? What is the explanation of the word dark?

The theory of yin and yang corresponds to normal air and spiritual energy. So whether spiritual energy is dark matter, it is a matter that cannot be observed by our current scientific means, and it also exists in the world. There are rumors that there is some difference in weight after death and before death, and this gap is the soul.

When Li Yifei heard it, he didn't believe it and thought it was natural to consume it. However, as soon as Chen Tuan's ancestor finished speaking, Li Yifei thought about it from this.

In other words, dark matter is equivalent to spiritual energy, or even spiritual energy, and it also exists in the world. Only practitioners can feel it and experience it. Different cultivation methods are also different. Only these substances exist can practitioners practice. Because of the principles of existence of the two worlds, the spiritual energy on the earth becomes less and less. In addition, the loss of the exercises makes practitioners only able to practice to the innate realm, which is equivalent to the entry level in this world.
