What is the fundamental reason why gods and demons, or the Holy Spirit and demons, can firmly sit in the divine position?

Is it their power? Or an invincible realm? Or is it the will to slaughter sentient beings with just one thought?

They are all, it can be said that these are the support for the Holy Spirit and the Demon God to sit firmly in the God's position, but they are not their roots.???

As the primordial spirits born from chaos, each primordial spirit represents a concept and a truth. As long as this world (not only the world of Nain) still exists, these primordial spirits cannot be destroyed, and the essence of the Holy Spirit and the Demon God is still the primordial spirit, so they are also immortal. Even if they destroy the body, soul and even consciousness of the Holy Spirit/Demon God, they will be reborn in the realm.

Of course, there are not no Yuanlings that have fallen, but even after these Yuanlings "dead", these Yuanlings still "exist" in this world.

The existence form of the Yuanling is difficult for humans to understand. When they first created the world (Neen World), a large number of Yuanlings died. Their bodies turned into nourishment for this world, and their consciousness no longer exists, but they are still "living" because the living beings they incarnate still exist, and the concepts they represent are still spread throughout the world. Therefore, these fallen Yuanlings still exist, and as long as they gather enough strength again, they can be reborn again and resurrected in a complete form.

The killed Lock Khan is actually "alive". His body was torn apart and turned into two moons in the air. His heart (core of power) was buried in the Red Mountain (but the dwarf who was killed thousands of years ago was dug out again), but He is still alive because the concept of "space" represented by Lock Khan still exists, so Lock Khan exists.

However, because Lockham's body and heart were not destroyed, but turned into bimoons and some source of power, he could only wander in the world of Nain in the form of consciousness, but could never be resurrected again.

Unless someone puts the two moons together and then puts Lock Khan's heart into it, then with the help of the ubiquitous concept of "space", Lock Khan can be resurrected and exist in this world in a complete form.

Having said so much, I believe you have a rough guess about Sawyer's understanding of the "existence" rules.

That's right, the "existence" rule that Sawyer realized is like the foundation of the Holy Spirit and the Demon God. As long as the corresponding concept still exists and the world still exists, then the creatures with this rule are immortal.

However, the "existence" rule that Saoya is perceived is a castrated version. There is no way. After all, Saoya is just a natural elf. Although his bloodline is noble and his connection with Yuanling is far from other creatures in the Nain world (1), he is not Yuanling after all, so he cannot represent a certain concept.

Note 1: The origin of all the wise creatures on the Nain Star is actually the "meat" of the fallen Yuanling. It has a trace of Yuanling's characteristics in the bloodline. However, due to the countless Yuanling incarnations and tens of thousands of years of reproduction, this characteristic is so thin that it is undetectable.

So Sawy's existence can only rely on his "traces" in this world.

What are the traces of Sawyer left in this world?

What he did and was recorded, the changes he had made to the world, and most importantly, the impressions of Sawyer, or memories.

In the previous consciousness space, those endless light spots actually represent smart creatures. The stronger the soul, the larger the light spots, and the silk thread represents the connection between these creatures and Soya. The closer the relationship and the deeper the impression, the thicker the silk thread will be.

However, understanding "existence" does not mean that Soya is immortal. For example, when encountering the power of elimination, with Soya's weak power, even if he understands the rules of "existence", he can only barely protect himself. In the end, he barely preserved his consciousness after sacrificing the impression of most people of him.

So once Saoya encounters a legendary strong man who has some understanding of the "existence" rule, as long as the opponent launches targeted attacks, Saoya will eventually be completely killed and unable to be resurrected.

As for why I realized the Elf King’s perception of swordsmanship during resurrection, I can only say that Soya and the Elf King are too close, and the Elf King is the most powerful among the people who have close ties with Soya. Therefore, when the "existence" rule resurrected Soya, it "by the way" helped Soya gain some benefits.

Of course, there are also reasons why the Elf King is not resistant, otherwise it would be very easy to resist the shallow "existence" rules with the strength of the Elf King.

However, the Elf King let Soya take a big advantage. Who is the Elf King Seluya? He is a level 95 demigod. A little bit of things exposed in his fingers is enough to make Soya eat enough!

So Sawy was really overwhelmed...

Just when he was resurrected, if the "existence" rules were not constantly protecting Soya's consciousness, plus the system, and the [Mysterious Veil] and other characteristics were also constantly working, maybe Soya would have been lost in the vast and infinite swordsmanship insights of the Elf King.

However, the benefits are obvious. Originally, Sawy's swordsmanship level was only level 45, and he was just touched the edge of "proficiency level". Under the insight of the Elf King, in just half a minute, Sawy's swordsmanship level soared, breaking through two bottlenecks in succession, skipping the "proficiency level" and directly entering the "expert level"!

So, the system went crazy. The rule of the system is that as long as the skill level is improved, even if the experience is accumulated, as long as the experience is accumulated, then you have to upgrade and strengthen your body!

So, the little energy accumulated in the system was instantly consumed, and the energy in the world had to be absorbed to replenish itself, and then converted into energy suitable for Soya to strengthen Soya's body.

Under the powerful power of the system, the energy of the heaven and earth within a radius of ten miles was directly stirred, and it gathered into a huge vortex and poured directly into Soya's body. Such a strange phenomenon naturally alarmed many old monsters living in seclusion. If the energy fluctuations were not too small, I would have thought that someone near the Somo Embassy had broken through the legend!

However, even if someone was not promoted to the legend, these old monsters still sent their descendants and subordinates, after all, judging from the scale of this strange phenomenon, it was at least a historical treasure that appeared in the world!

There were even a few "paupers" who had just been promoted to legend. They didn't even want the face of being a legendary strongman, and left their seclusion and rushed all the way to Sawyer's place.
