Receiving such an answer, Catherine felt that her whole person was wrapped in a strong sense of powerlessness. She knew that Yushui did not lie to herself, and as a friend of West Rum, she could clearly feel Yushui's unwillingness and helplessness.

"What does our world look like in your mind?" Rain did not rush to begin explaining the truth of the world.

After a moment's thought, Catherine replied, "I can only answer this question with what I have learned about history and geography." My hometown is the royal city of St. Os, Daxt, located on the eastern continent. The term "Eastern Continent" comes from the Bercy Empire. The great navigator Silphat sailed westward hundreds of years ago, and successfully reached the human empire of Belcy on the western continent through the open sea, and the people of Belcy called Silfer the Orientals, and Syphat called them Westerners. Hence the naming of the two continents.

"After a lot of communication with the human kingdoms of the Western Continent, we slowly confirmed that in fact, the Eastern Continent and the Western Continent are just two ends of an entire continent. Between the two continents lies a vast realm of the dead, a world of the undead, ruled by a maximum of eight kings. The Dead Realm is directly bordered by the Bercy Empire, and is separated from the countries of the Eastern Continent by a vast desert. This is also the reason why the human nations of the Eastern Continent did not know about the existence of the Death Realm for a long time.

"Beyond the continent is the boundless sea, and humans have only explored a small part of the ocean so far, so we don't know if there are other continents in the depths of the ocean.

"Beneath the continent we live in, there is an equally vast underground world. The underground world and the surface world are usually connected by some natural caves. Exploration of the underworld is as limited as the ocean, as there are many abysses scattered in the underworld, and the powerful demons that inhabit the abyss do not welcome human visits. This is what the world has known so far, and which has been proven.

In addition, in the religious codes of mankind on the Eastern Continent, the existence of the heavenly realm is also described. The celestial realm is made up of many floating paradises on which the gods live. The study of the celestial realm is primarily theoretical. But I think you know more about the gods than I do. Because through research, we believe that the Elven Empire was established in the late Age of the Gods, when the gods had not fully returned to the heavenly realm, and they were still active on the continent. By the way, the so-called Age of the Gods is our expression of the earliest historical age that can be examined, about 100,000 years ago. ”

Catherine finished in one breath, and then looked at the rain expectantly. She believes that the rain will solemnly present the truth of the world, which will never be as simple as she says.

Sure enough, Yushui said: "It seems that human understanding of the world is still in its infancy, but I have no intention of teaching you, so I will talk about the appearance of the world explored by the empire in a way that you can understand."

"As you said, the world is divided into three levels, the gods dwell in the upper realm, which can also be called the celestial realm or the divine realm, the middle realm where the continents and seas are located, and the lower realm where the lower realm is located. This division is due to the fact that there are clear boundaries between the three levels, and the creatures and races that inhabit each level are also very different.

"At that time, the empire spent a huge amount of manpower and material resources, and the two elven kings led expeditions to the upper and lower realms respectively. When they returned, scholars sketched a complete picture of our world based on the information and evidence they had obtained.

But the whole picture of the world is not the truth of the world. In the midst of the two expeditions, His Majesty the Elven King Gauvis, who has gone to explore the Upper Realm, discovers a secret of the gods. This secret is directly related to the return of the gods to the upper realm. Unfortunately, the details of this secret are only known to a few Elven Kings. Similarly, the Elven King who went to the Nether Realm to explore was the Sirum you had seen, too...... Gained some secrecy. ”

The rain stopped at this point, and I wonder if it was because of the mention of West Rum. Catherine had heard Rain mention the Mud Elf King before, but this time she could clearly distinguish her different attitudes towards the two Elven Kings from Rainwater's words - the Elven King Gauvester was addressed as His Majesty, while the Mud Elf King was only called Sirum.

Gao Wei is the ancestor of the elves of the Snow Mountain, and it can be said that the northern school of research on this elven king is an authority. Due to the fact that the Snow Mountain Elves live in the snow-capped mountains of the Northern Kingdom and rarely show up, Catherine only happened to see a delegation of Snow Mountain Elves when she was in the Northern Saika. The Snow Mountain Elves are all silver-haired, which left a deep impression on Catherine.

In short, the two elven kings, with their respective discoveries, laid a hidden danger for the later disputes of the empire. Rain obviously doesn't want to go into detail about this history, "and the secrets they have discovered are 'the truth of the world'."

"Unfortunately, I don't know the specifics of 'The Truth of the World'. For so many years, I have only deduced some clues from the actions of your majesty, but some of them have been confirmed by me, which is the 'knowledge' that I can tell you. ”

The rain stopped for the second time, as if to sort out the thoughts. Catherine knew that what was going to be next would be the most crucial thing.

"1. The world we live in is not only the three-level world that we see, but also the soul world of all those who have souls;

"The second and third worlds are not static, and their changes have a lot to do with the soul world of those who have souls;

"3. The world of the souls of all those who possess souls is interconnected.

"The above three points are the 'truth of the world' that I can tell you. ”

After hearing this, Catherine thought silently, the three points that the rain said and her understanding of the spirit world overlapped and corroborated each other. For example, the third point is that all spirit worlds are interconnected, which is very similar to the mystery of the spirit world described by the Will of Fire - all spirit worlds lead to the same place, the so-called ultimate domain. Catherine was able to travel from her own soul world to the soul world of the blood beast, and that was through the ultimate realm.

However, there are other two points that Catherine is more difficult to understand. "I can understand the third point, because the fact that I am here has a lot to do with the third point. So could you please explain a little bit more about the first and second points?"

"To understand the first point, you need to understand the second point first. By 'change' in the second point, I don't mean those natural changes, not rain and thunder, not volcanic earthquakes, not tsunami meteorites, but changes between the three realms. To put it simply, the position of the three realms is not eternal, and after the current realm disappears, the middle realm will become a new lower realm, and the original upper realm will become a new middle realm, and the new upper realm will be reborn. ”

Catherine subconsciously opened her mouth wide after hearing this. "Why did the lower realms disappear?" she asked.
