Spirit summons? I want to do it myself!

Regarding the hypothetical world tree, Lido believes that even if it is not the world tree, it should be a similar existence.

Lido also has reasonable guesses about the part above the trunk.

If monsters are the dark side of the magical continent, then elves are the opposite pole of purity. The connection between the two is so deep that they are like two sides of the same coin.

If the roots of the World Tree are spread throughout the earth veins of the entire planet, then the part above its trunk is likely to be located in the secret realm of the elves.

Perhaps, elves and monsters were both born from the World Tree, but one was born from the dark roots buried deep underground, and the other was born from the Tree of Life bathed in sunlight and the purple moon.

That is why there are two species with such opposite characteristics, which are natural enemies of each other and can devour each other's energy to grow.

Some people may ask, why has no one discovered the existence of the World Tree even though monsters and elves have been around for nearly three thousand years?

Because so far no one has reached the secret realm of the elves, no one has reached the place where monsters were born, or no one has brought the news out of the lava cave alive.

And there is no evidence that the trunk of the World Tree must be towering into the clouds and covering the sky, right?

The technology in the magic continent is underdeveloped, and the supernatural system is actually very fragile. Since the places where monsters are born are protected by dark barriers, it doesn't make sense that the elves' secret realm has no protective measures, right?

It must be a powerful and secretive protective measure! So it's normal that no one noticed it? !

After talking about the general guess about the World Tree, the second question is the mystery of the birth of the Black Skull.

The tomb in the lava cave must have existed before the meteorite fell.

The owner who could dig rocks and build a tomb of this size in such a dangerous place must be powerful and cruel! Because the manpower and material resources consumed and the casualties caused must be numerous!

Although there is no evidence of the original appearance of the tomb after it was sealed, from the luminous pearl on the top of the tomb that has been shining for thousands of years and the three huge coffins, Lido can imagine the richness of the burial objects at that time, and most importantly, the number of people buried with the tomb was probably not a small number!

Originally this was nothing, as many ancient tombs unearthed on Blue Star in the previous life had similar situations, but an accident happened!

Lido didn't know when this lava cave was created, but it must be thousands of years old.

When an energy node was formed here and the World Tree took root, it must have pierced through the mountain wall and entered the two burial chambers.

As mentioned before, not every lava cave will give birth to monsters like ghosts, and monsters like skeletons usually appear with ghosts, and ghosts and skeletons are usually born in burial places with dense corpses.

Because the World Tree took root in the tomb and there were a large number of corpses in the tomb, this was equivalent to the special factors encountered when runes were generated inside the roots of the World Tree, which made the roots of the World Tree eventually form the birthplace of the two monsters, ghosts and skeletons.

But we must be clear that not all ends of the world tree roots will form lava caves and the birthplace of monsters!

The energy erupted from some geomagnetic energy nodes is not enough to breed a large number of monsters, so lava caves will naturally not form. However, they may form the birthplace of monsters, that is, a small monster group.

The energy erupted by some energy nodes is only enough to give birth to a wave of monsters. If this energy node happens to be located in a burial ground, and a root of the world tree happens to extend over it, then it is very likely that a wave of ghosts and skeletons will be born here, providing a suitable environment for the monsters to grow.

This is also the main reason why burial is not popular in the magical continent nowadays and cremation is chosen instead.

There is no need to say much about the ghost issue, let’s get back to the black skull issue.

The roots of the tree where the skeleton is born actually nurture the soul fire in the skeleton's eyes. Only when the soul fire is attached to the corpse will the monster skeleton be born.

Therefore, soul fire is the lifeblood of the skeleton. It should have similar characteristics to the ghost, but each has its own focus.

The objects that the soul fire attaches to should not be limited to human corpses, and it is probably not picky about the degree of decay of the corpse. As long as the bones are still there, it will be fine. Even a fresh corpse will probably quickly decay to the point where only bones are left, and the soul fire will strengthen the bones of the corpse.

There are the bodies of the tomb owner and a large number of buried companions in the tomb, and there should have been quite a few skeletons born at the beginning.

However, due to the special location of the tomb, it is not only located in the mountain wall, surrounded by hard stones, but also located on a cliff. The bronze door closing the entrance is also very thick and tough.

However, the skeletons have physical bodies, and the first white skeleton that was born naturally did not have the ability to dig mountains and rocks, which resulted in all the skeletons that were born being trapped in the tomb.

Skeletons, like ghosts, can advance by devouring their own kind, most likely by devouring the opponent's soul fire and the energy in their bones. Judging from the situation in the tomb, the devoured skeletons should have been shattered into pieces in a physical sense.

Since they can’t get out of the tomb, the skeletons can only kill each other!

No matter how many corpses there are in the tomb, they are limited after all. The only winner decided by the skeletons devouring each other is the predecessor of the black skeleton!

Lido didn't think that the number of skeletons born from the corpses in the tomb could directly advance to a black skeleton, and estimated that the only winner in the end would be a gray skeleton.

However, although the speed of soul fire being bred in the place where the skeleton was born was very slow, it was still continuously producing soul fire, and there were no other formed bones in the tomb except the gray skeleton, so the final destination of these newly born soul fires was to be swallowed by the gray skeleton.

The gray skeleton was able to continue to advance, and eventually advanced into a black skeleton over time.

However, while the Gray Skeleton was getting stronger as it advanced, the stones in the surrounding mountain walls became harder due to the long-term infiltration of dark magic elements and turned into obsidian ore, which hindered the Black Skeleton's efforts to dig a passage out.

Until the attack power of the black skeleton increased to a level that exceeded the strength of the obsidian ore.

However, over the long years, Black Skull has not been able to successfully dig a tunnel. This has created a kind of inertia, causing Black Skull to no longer pay attention to the matter of digging tunnels, and it seems to be more of a random formality.

So the Black Skull was trapped in the tomb, and no one discovered any trace of its existence until Lido arrived!

Lido's action of widening the entrance and exit passage for ghosts was undoubtedly the clearest guidance to the Black Skull, and also gave it the motivation to dig the passage, which led to the subsequent development!

And why did Lido say that no more skeletons would be born in the lava cave?

Obviously, the roots of the World Tree can still breed soul fire! Even if there are no bones in the tomb, now that the passage has been opened, the soul fire can still float out and find an object to attach to.

Well... let's put it this way, Lido plans to use obsidian ore to completely seal the tomb where the skeleton was born, all the way to the main tomb chamber.

With the isolation of the obsidian ore, the soul fire cannot come out, and without an object to attach to, the soul fire will eventually go out.

From now on, Lido does not plan to move this tomb. Even if someone comes in later to mine obsidian ore, Lido will specifically avoid the side where the tomb is located.
