"And what about the difference? As you said, there should be differences between the four levels of astrolabe to divide into four levels, right?"

As for Shalan's question, Reina seemed to have been prepared, he nodded slowly, and continued to speak: "That's right, there is indeed a difference, my Black Iron Astrolabe is the lowest-level astrolabe, which records the directions and information of the nine worlds around the nine worlds I am in.

In other words, the world recorded on the black iron astrolabe is not fixed, but constantly changes with the user's location, and with the increase of the level of the astrolabe, the more the number of places and information recorded in the world, the farther the astrolabe can be teleported with the higher the level.

As far as I know, the bronze astrolabe on top of the black iron astrolabe recorded eighteen worlds, the silver astrolabe recorded thirty-six worlds, and as for the golden astrolabe, it is said that only three were built at the beginning, and seventy-two worlds can be recorded, and none of the worlds are unreachable!"

Eighteen worlds?

Now Sha Lan has naturally determined that the bronze disk he got with the Molten Fire Staff in his hand is the Bronze Astrolabe, which is a level higher than the Black Iron Astrolabe that Reina had in mind, plus when he saw Reina use the Black Iron Astrolabe before, he also memorized Reina's techniques and spells, and now he needs to use it experimentally.

It was only when Sha Lan was thinking about the bronze astrolabe in his hand that he heard Reina speak again: "In fact, among the four levels of astrolabe, the black iron astrolabe is the worst one.

Its role can only mark the world, and if you want to open the door to another world, you must have a lot of power as support, with the corresponding altars and preparations, before you can really go to another world.

If the astrolabe in my hand was even a bronze astrolabe that was only one grade higher, I wouldn't have to spend so much time and effort preparing these extra things. ”

With a move in his heart, Shalan's face showed a hint of curiosity that had knocked on the benefits, and he asked Reina: "Why doesn't the Bronze Astrolabe need to prepare those, is it only one grade worse than that?"

"In fact, the reason why there are grades is divided is because in the main material world of that era, the black iron astrolabe was mainly used by the people and the military, and it was naturally not necessary to be so delicate when traveling to and from various worlds.

Moreover, due to the large number of Black Iron Astrolabes, in order to prevent some people from privately using the Black Iron Astrolabe to travel to and from the major worlds to do things that endanger the main material realm, the Black Iron Astrolabe must be used with a large device and a huge amount of energy.

Moreover, the channels opened by the Black Iron Astrolabe are all large-scale channels, not made for a few people, and the energy required is naturally very large, so there is naturally no way to add a self-sufficient energy supply device to the Black Iron Astrolabe.

However, the other three levels of the astrolabe are completely different, and those three levels of the astrolabe can open the passage to the individual and the few, and the energy required is greatly reduced.

The Bronze Astrolabe may still need a lot of energy from the user to open, while the Silver Astrolabe and the Gold Astrolabe do not need the user's energy at all, and the astrolabe at this level can be completely self-sufficient.

In fact, I was just going to take a few people such as elves to other worlds, and it was completely fine to open a small passage, but it was not easy to find a black iron astrolabe, and I couldn't prepare for those preparations, and the black iron astrolabe could barely be used. ”

"The Bronze Astrolabe can be used without those preparations, which is really a good thing, but unfortunately we didn't find the Bronze Astrolabe. ”

Listening to Shalan's words, Reina smiled: "Even if it is a black iron astrolabe, its value is equivalent to a daylight-level witchcraft, it is a super high-level witchcraft second only to the legendary witchcraft, if we find the bronze astrolabe, I really don't have anything more to pay you as a reward." ”

At this end of the talk of astrolabe, Sharan chatted with Reina for a few more words, and then returned to his seat to continue meditating.

There was nothing to say all the way, when the train returned to the city of Salingrad on the border of the United States of the British Federation, before the train stopped on the platform, Sharan opened the window, said goodbye to the others, and soared into the sky with the feather badge, and when he came to the sky, he summoned the Nian beast Terry to turn into a huge silver giant bird, carrying Sharan in the direction of Solan City.

I have to say that compared to the planes and airships of this era, the flight speed of the giant bird transformed by Nian Beast Terry has reached an extremely amazing level, and the third-level Nian Beast is really good in terms of speed alone, just in less than five hours, Nian Beast Terry carried Sha Lan back to the sky above Solan City, and then Sha Lan quietly returned to the urban area of Solan City, put away Nian Beast Terry and returned to his home in Ogins Villa.

Knowing from Hugh's mouth that no one had come to him in the past few days, Shalan was relieved, checked the progress of Hugh's meditation method practice, guided him on some deficiencies in schoolwork, answered some questions, and then Shalan returned to his room.

Although he was very curious about the Bronze Astrolabe in his hand, this place was not the place to study the Bronze Astrolabe, once Sha Lan accidentally opened the entrance to a world and ran out of some kind of monster, there was really no way to explain the origin of the monster.

So before finding a suitable place, Sharan did not plan to rashly study the Bronze Astrolabe.

Besides, it's the end of March now, and the end of May is the final exam at the end of the first half of the semester, if this exam is too bad, there is no qualification for the transcendent exam in the next semester, in other words, there are still two months to usher in the final exam of the first semester, at least Shalan must have to get a middle and upper grade, so he has indeed to concentrate a little on some exams and study problems recently.

Fortunately, everything has been on the right track recently, but there is no need for Shalan to worry about anything, and he can study and practice at the same time, and have time to go out with Yi Wen, eat and drink, this kind of life is actually Shalan's favorite kind of life.

It's just that Shalan didn't know that in the Orlan Seven Alliance, which can be regarded as half of his hometown, a blue-white undercurrent gradually spread in the Desert Chieftain Kingdom in the Oran Seven Alliance, as if it had a tendency to spread outward!
