Ordinary cultivators don’t dare to behave like this in front of Chen Tuan’s ancestor. After all, people’s names are followed by the word ancestor. Even the top cultivators in this world should respect him when they see him. The land respectfully calls the ancestor, because people's seniority is placed there, and the cultivation base is also placed there. But Li Yifei did it, and Chen Tuan didn't care.

"There is the Yin Cao Jifu!" Chen Tuan said affirmatively. Li Yifei quickly turned his gaze back and said, "Where is it? Underground?"

"here!"

"Here?" Li Yifei opened his mouth wide and couldn't believe it. He quickly asked: "Here? This world is the Yin Cao Netherworld?"

"Not bad!"

This is actually subverting Li Yifei's cognition. He was a little hard to accept, and it took a long time to say: "Then why... there are people everywhere here?"

"Who said that Yin Cao Jifu is the place where ghosts are treated?"

"Um...it's not right, there is a fool, I can feel it!" Li Yifei said.

"The soul, the spirit!" Chen Tuan said leisurely.

I'm going! Li Yifei seemed to have been opened a door. The dialogue between the two was casual and there was not much logic, but now he was shocked, and he could think of many things by linking these things.

Is it possible that this world is the legendary Yin Cao Netherworld on earth, or the so-called heaven or **** in the Western world? In short, the place where people go after death?

"Not a cultivator will also absorb aura, as long as it is a life, there will be aura. The more intelligent the animal, the more aura, the more aura will be released after death, and often after death, the aura Will come to this world, it is also the so-called soul, soul, of course, after the death of ordinary people, the spiritual wisdom disappears, I am afraid that they can’t persist in coming here, which is the so-called go to the underworld, their spiritual wisdom is often at the moment of death. It will slowly dissipate and permeate the world, let alone other animals.":

"So this is the reason for the aura of this world?"

"If there are more cultivators, more auras will be consumed, and more auras will be released after death!" Chen Tuan said.

"But...what does it have to do with the Yin Cao Jifu? Old ancestor, you can just talk about it directly, the kid is really a little bit clueless!"

"Haha!" Chen Tuan laughed loudly. It seemed that he hadn't said so much for a long time. He took a sip of wine and said, "Since you want to listen, I will start from the beginning. These things are the most important principles between heaven and earth. You should also understand!"

"Good!" Li Yifei nodded happily.

"In the beginning, there were two divisions between heaven and earth. One is your earth, which is also the foundation of all things. There are countless kinds of animals in the world, and humans are just one of them, but humans are also the first to understand the truth of the world, so Only in order to cultivate, open up oneself, and create the world of oneself. The second is the world, which is not created by the cultivator, but always exists, exists between the heaven and the earth, and exists in the world."

Li Yifei seemed to be listening to the fantasies, but he did not interrupt Chen Tuan.

"In the two worlds, after the people on the earth die, the aura will either disappear or come to this world. It is said that they have gone to the Yin Cao Netherworld, waiting for reincarnation, the cultivator dies, the aura will dissipate more, and more will come. In this world, if some cultivation bases are strong, then the soul may remain and become evil, and those who have cultivated to the Yuan Ying stage can be regarded as a world of their own, and they have brewed the Yuan Ying, which is often said to have a second. A life, even if it is physically dead, can escape its life, it only needs to re-cultivation."

"Here, the orcs also have spiritual wisdom, and they can also cultivate, which is much easier than on the earth. This balance was broken hundreds of years ago. I just listened to your account of the changes that have taken place on the earth in the past few hundred years. I also feel a little bit. It seems that the original decision was right. I have been stuck with this question for years. Is the original decision right? For practitioners, the world is full of spiritual energy and suitable for cultivation, but it seals the two. The passage of this world will make it impossible for people to return to their hometowns. It also triggered the battle of the world, and the lives were overwhelmed. The original intention was to let ordinary people live a good life, but it was counterproductive and harmed them!"

"However, the earth was saved because of this, but the people in this world are suffering!"

It may not necessarily be saved. People are always selfish and selfish. After all, people’s hearts are separated by their belly. The pollution, wars, and entrapment on the earth have never stopped.

From the aspect of spiritual energy, it seems to be rescued, because Chen Tuan then talked about balance, which is the way of yin and yang balance. If the cultivators were allowed to continue, then the earth would probably be destroyed too. This is not alarmist.

As for this world, four-fifths of the top cultivators died after that great war. Although it was impossible to destroy the world, because the top cultivators died, the resources they needed to occupy became much less. In addition, this world is already full of aura, at least it can be harmful for many years.

Li Yifei couldn't help but feel happy when he heard this. He joined the cultivators to protect the earth, so he drove all the cultivators to this side, and...regardless of the life and death of this side. From the past years, this is a very moral choice.

Through Chen Tuan’s description, Li Yifei came up with a word, which is also a word that can be seen in science magazines in recent years-dark matter! Whether it is China, Europe or the United States, they are all studying this kind of material. Is there any dark matter? The answer is yes. Through scientific observation and analysis of theoretical physics, it can be concluded that dark matter exists, but what is dark matter? What is the explanation for the word dark?

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

Li Yifei didn't believe it when he heard it before, thinking it was natural consumption, but as soon as the ancestor Chen Tuan finished speaking, Li Yifei thought about it.

In other words, dark matter is equivalent to spiritual energy, or spiritual energy, and it also exists in the world. Only the cultivator can feel and experience it. The feelings of different cultivation methods are different. Only when these substances exist, the cultivator can cultivate. Because of the principle of the existence of the two worlds, the spiritual energy on the earth has become less and less. In addition to the loss of the technique, the cultivator can only cultivate to the innate realm, which is equivalent to the entry level in this world.

Although it is already very powerful on the earth, it is also the result of Chen Tuan's painstaking efforts. Li Yifei felt that it was instantly smooth when he thought of this.
