The wizard world is powerful.
So powerful that Earth civilization is utterly unqualified to resist it.
Let alone a full-scale invasion by the wizard world, the entire Earth could not even withstand a single student from a wizard academy in the Put Kingdom.
Elva had studied sorcery in this academy for a year. He could guarantee that if he brought one hundred first-year students from this academy, one hundred students who had stepped into the "apprentice sorcerer" rank, to Earth and had them all obey his commands, he could dismantle the governments of all Earth nations and make the entire planet submit to the sorcery of these apprentice sorcerers.
This demonstrated how powerful the entire wizard world must be.
Although the civilization level, living environment, and living standards of the entire wizard world had remained at a medieval level for hundreds of billions of years, these extraordinary individuals had reached the peak of their power.
Elva's only solace was that the introduction to myriad worlds class did not mention any traces of Earth civilization.
However, he then thought that the absence of Earth civilization's traces did not mean it had not been invaded by the wizard world.
Consider the worlds invaded by the wizard world.
Take the Shadow World, for instance. It was a world with the volume of an infinitely large universe, composed of countless planets, stars, and galaxies.
Who could guarantee that among the countless star systems in the Shadow World, not one had eight planets, and one of those planets was Earth?
Earth, in the Shadow World, was infinitesimally small. Would the sorcerers who invaded the Shadow World meticulously record every single planet in the universe and explain it in the introduction to myriad worlds class?
It was impossible to even think about it.
In such a vast inter-world invasion, even the Shadow World was considered a very weak world among the many invaded by the wizard world.
There was not much record of the entire Shadow World, the entire world. The focus of the class was on the powerful worlds that opposed the wizard world, especially the divine worlds.
There would not be many records left in a weak world like the Shadow World, a world that could be completely destroyed by a Level Seven Rule Sorcerer in three seconds.
The civilization of the wizard world would not value such a mere weak world.
If Earth civilization were just a planet in the universe of the Shadow World.
Even if it truly existed, it would not be recorded by wizard civilization, simply because extremely insignificant things are not remembered or recorded by the powerful.
Therefore, Elva could not determine whether Earth civilization had been invaded by the wizard world.
He also could not determine whether Earth civilization existed in a world destroyed by the wizard world or in a world not destroyed by the wizard world among the myriad worlds.
At this moment, he could only strive to cultivate sorcery and improve his wizard rank. Perhaps after reaching Level Four Morning Star Sorcerer, he could travel to other worlds and find the Earth civilization of his past life.
Level Four Morning Star Sorcerer.
What did that concept entail?
There were nine levels of sorcerers.
Sorcerers at Level Seven and above controlled rules, hence they were called High-Level Sorcerers.
High-Level Sorcerers were the absolute foundation of the wizard world; it was precisely because of the numerous High-Level Sorcerers that the wizard world had the capital to invade other worlds.
Many worlds did not have beings comparable to Level Seven sorcerers. Among the myriad worlds, only a very few worlds possessed beings comparable to Level Seven sorcerers or higher.
Level Eight sorcerers were also known as True Spirit Sorcerers. Beings comparable to Level Eight sorcerers were extremely rare among the myriad worlds.
Only in the divine worlds did beings comparable to Level Eight sorcerers exist, known as gods with "Great Divine Power."
The realm of Level Nine sorcerers was a fantasy realm proposed by sorcerers. Since ancient times, no sorcerer had ever reached Level Nine. In the exchanges among High-Level Sorcerers, it was believed that perhaps only when the wizard world had devoured all the worlds in the divine worlds and the star realms could the conditions for the birth of a Level Nine sorcerer be met.
Currently, Level Nine sorcerers were merely legends, mere fantasies, hypothetical realms that no one had achieved.
Sorcerers from Level Four to Level Six were called Middle-Level Sorcerers.
If High-Level Sorcerers were like stabilizing pillars, the absolute trump cards, foundations, and killing moves of the wizard world,
Then Middle-Level Sorcerers were the soldiers fighting on the front lines.
In the wizard world, Middle-Level Sorcerers were the backbone. Only by reaching the rank of Level Four Morning Star Sorcerer did one possess the qualification to fight externally.
Low-Level Sorcerers, who were not Middle-Level Sorcerers, would die instantly upon stepping into the endless star realms, thus naturally lacking the qualification for external combat.
Sorcerers from Level One to Three were Low-Level Sorcerers.
Low-Level Sorcerers were the bottom-tier forces of the wizard world, but this referred only to the central continent, the thirteen underground layers, and high-dimensional worlds.
If it were a remote continent like the Emerald Continent, a Level Three sorcerer could still live quite well.
After all, the Put Kingdom only had a single-digit number of Level Three sorcerers.
Level One sorcerers were not the lowest existence.
This was because Level One sorcerers also had another title: Formal Sorcerers.
Since there were formal ones, there was also the concept of informal ones.
In the wizard world, the title of sorcerer was sacred and the only cultivation system. Naturally, one could not be called a Level One sorcerer simply by learning some sorcery.
Only by condensing a crystal in the sea of consciousness that could inscribe permanent sorcery was one a true Level One sorcerer, a Formal Sorcerer.
Those who could only temporarily construct mental runes and sorcery runes in their sea of consciousness to cast sorcery were merely apprentice sorcerers, not Formal Sorcerers.
Whether there was a crystal in the sea of consciousness and the ability to inscribe permanent sorcery was the standard criterion for distinguishing between Formal Sorcerers and apprentice sorcerers.
Apprentice sorcerers were those who studied sorcery, could use sorcery, and had not yet entered the Level Nine sorcerer system; they were the reserve forces of Formal Sorcerers.
Apprentice sorcerer itself was a transitional stage. In sorcery academies in places like the central continent, apprentice sorcerers were not further classified, as it was not difficult for these academies to help someone transition from a mortal through the apprentice sorcerer stage to a Level One sorcerer.
However, for rural academies, the apprentice sorcerer rank could be further divided into first-class apprentice sorcerers, second-class apprentice sorcerers, third-class apprentice sorcerers, and so on.
There was no other way; it was difficult for remote continents to treat the apprentice sorcerer stage as merely a transitional realm, as a mortal might spend a hundred years studying sorcery and only remain an apprentice sorcerer.
This situation was common, widespread, not an exception.
It was like how amateur Go players were divided into nine dan.
Even though apprentice sorcerers were amateur and not professional, due to their sheer numbers, internal ranks still needed to be established, otherwise, it would be difficult to differentiate the combat power between two apprentice sorcerers.
Elva was merely an apprentice sorcerer.
