On the Er traversing ship, in addition to those refining knowledge, the most important thing is these space studies.

With the space science of the wizarding world today, it is absolutely impossible to travel through the world, and Phil was able to do this for other reasons. Just like when he was in the Black Rope Tower Academy and in the Black Rope Fortress, the maximum distance of the teleportation array was far from meeting the requirements of traveling through the world, and it was already the highest-level spatial science in the Dark Wizard Regional Academy, and every time he teleported, there was a very uncomfortable feeling.

That's because, the spatial principle of the teleportation array is that in the space between two locations, a passage is directly torn apart, which is very barbaric and extremely inefficient, which is because the city does not know much about space.

During the ancient wizarding period, the powerful wizards at that time had more profound spatial knowledge, and their application in teleportation was also very good, such as the spatial transformation illusory portal of the first ruin encountered by Riffel in the Forgotten Lands, and the spatial gate at the entrance to the inner ruins not long ago, all of which were their applications of spatial science. Their principle seems to be able to fold the space, to fold the space between two locations very thinly, so that it is very easy to teleport. It's just that I only know the general principle, and it is very difficult to restore it, countless wizards have conducted research on this space door technology, but they have obtained very little, they have faintly come up with an answer, if you want to create this kind of space door, in addition to the necessary space knowledge, it seems that you also need a very strong strength, which is not something that a third-level wizard can do.

Today's teleportation array, compared to the space gate, is simply a world of difference, and the space technology of the ancient wizard period is much more powerful than the ancient wizard period.

The space gate technology of the ancient wizard period, no matter how powerful it is, is only a teleportation between points and cannot be changed, but the space technology of the ancient wizard period can allow Phil to teleport back to that starry sky anywhere in the wizarding world!

The spatial knowledge contained in it can no longer be understood by a little wizard like Phil, even if his strength has reached the level of an ordinary third-level wizard, even if he has a cactus ball elf, it is difficult to understand.

For example, Phil is currently an elementary school student learning addition, subtraction, multiplication and division, if a teacher explains to him what an equation is and what a function is, he is still a little familiar with it, but if a teacher is talking to him about group theory, topology, Galois theory, Fermat's theorem, Poincaré conjecture or something, he can just take out the wizard rope and blow you up, understand?

The wizards of the ancient wizard period directly developed spatial science to the extent of traveling through the world and invading the world, almost standing directly at the pinnacle of spatial science.

Therefore, the cactus ball elf is not omnipotent, and some things can only be truly understood after he reaches that level.

Of course, these confusions about space science did not stop him from using the space technology of the ancient wizard period to travel back to the starry sky in the ruins of the inner layer.

It stands to reason that he can shuttle back from any place in the wizarding world, which means that he can use this ability to escape in an emergency, but this is only theoretical, if you want to shuttle back, you need an extremely large amount of spiritual power and magic support, and the farther the distance, the required mental power and magic power will increase exponentially.

With Phil's strength, he can probably only shuttle back from Desert City.

So as soon as he returned here, he couldn't wait to walk into the crossing ship, sit down to meditate, and regain his strength.

It's only been a few days since he'd left here, and the long-awaited Voyager hasn't changed in the slightest, and it's been a long time before he can actually start repairing it.

He didn't stay long, and after recovering his strength, he went out to have a look.

There is a circle of lizard monsters around the space door at the entrance of the inner ruins, and they are forbidden to approach around the space gate, after all, even if the original lizard monster shooting designer planned to use these lizard monsters to guard the ruins, it was impossible for them to destroy the things kept by the refining masters in the inner ruins.

These lizard monsters, which had lost control, fled one after another after encountering Phil, who had completely let go of his strength, and then a figure more than three meters tall rushed out from the surface ruins, which was the lizardman who had fought with Phil before.

When the enemies saw each other, their eyes were red, and the two immediately fought together.

Not long after, Phil was defeated and fled back to the ruins, meditating on his recovery while reflecting on his previous battles and summing up his gains and losses.

After that, you will travel through the desert city.

For a long time after that, Phil would return here to fight the lizardmen, which allowed him to grasp his true strength little by little, and in the end, the lizardmen's strength had recovered to the strength of a third-level wizard, and was finally defeated and killed by Phil, ending his long sparring career, of course, those are all for later.

The chaos in Desert City finally reached its peak in the second half of the night, and countless wizards and wizard apprentices fought each other, and the scope of the battle soon spread from the location of the Central District near the Xicheng District to the entire Central District, and part of the southern part of the ruins. Only Xicheng District is still quiet, but when it was almost dawn, there was still a group of people coming from Xicheng District, driving out the wizards who had encroached before, and quickly encroaching on the empty single building, the scope of Xicheng District was reduced by half at once, but the original single building here was not affected, and it was not even disturbed.

Phil quickly saw that there should be Elenor's involvement, and only she knew how many wizards were really unable to come back.

The night passed, the Desert City regained its calm, many people noticed the chaos of last night, only the haters understood that the interests in the Desert City had been divided again, and a lot of idle wizards had put all their net worth into it, it was like a big gamble, if the bet was won, they still had a way forward, and if they lost, there would be nothing.

In this gamble, the White Wizard Regional Academy won the lion's share and became the only winner, and the Dark Wizard Regional Academy lost a little, they underestimated the strength of Wizard Heloise and her hatred of the Dark Wizard, and they did not expect Wizard Elenor to return in time.

But they are not the worst, the worst are the idle wizards.

After this night passed, there were many people who were never seen again.

But none of this had anything to do with Phil, and he wasn't even in the mood to watch, until early in the morning, the wizard Elennor came to pick up Lina and Aboud, and he invited her to the parlor to discuss something with her.
