Feng Chou spent more than a year to refine this spell into a mudra spell. As long as he wanted to, he could keep the teleportation halo active.
The number of spatial spells among the level-seven spells suddenly increased. This was because it was not difficult for mages above level-13 to understand and leverage the rules of space.
The spatial spells among the level-seven spells included "Mage's Mansion," "Advanced Teleportation," "Otherworld Teleportation," "Phase Gate," "Banishment," and so on.
The spell "Mage's Mansion" was similar to the Mage's Secret Chest, but it was obviously much more advanced.
Just like the Mage's Secret Chest, the Mage's Mansion was also a ritual spell that was difficult at first but easy later on. In order to use this spell, the Mage had to perform a very complicated ritual. Under the blessing of this ritual, the Mage would project his soul into the Astral Plane.
The astral plane was a very strange plane. Some mages even thought that it was not a plane.
The astral plane was very vast, more vast than any known plane. Even the bottomless abyss could not compare to the astral plane because no one knew where the boundary of this plane was.
Another amazing thing about the Astral Plane was that it seemed to be adjacent to any other world. In the Arcane Era, there were even arcanists who believed that all planes were actually part of the Astral Plane, and that the Astral Plane was the main body of the world.
According to this arcanist's theory, Feng Chou felt that the astral plane was like the space of the universe in Feng Chou's previous life, and the various planes and worlds were equivalent to the planets and galaxies in his previous life. It was just that the way they existed was completely different.
After the soul projection reached the astral plane, it would find a suitable place. Through the power of the ritual, it would create and nurture a small independent space in the astral plane that was similar to a half-plane but not up to the standard of a half-plane.
Under the effect of the ritual, the independent space would grow to the size of a mansion of hundreds of square meters and finally stabilize under the effect of the ritual.
After the space stabilized, the mage would anchor this space to the main material plane.
After the anchor was successful, the mage would set up an otherworld teleportation circle in the mansion to connect the mansion's plane to the main material plane. The owner of the mansion could activate this teleportation circle at any time to transport items and creatures in and out of the mansion.
At this point, the Mage's mansion was basically completed, and the ceremony was over. As for how to decorate the interior of the mansion, it was up to the Mage. Some Mages would even imprison beautiful women in the mansion.
Mages who owned Mages' Mansions no longer needed Space Items. Mansions could completely replace Space Items.
The security of a mage's mansion was very high. The astral plane was vast and boundless, and there was almost no life. Moreover, in the astral plane, you couldn't see the mansion's space, just like how you couldn't see the main material world, lower planes, or upper planes. The relationship between the planes and the astral plane was very strange. They coexisted in a relationship similar to parallel space.
Therefore, a small mage mansion hidden in the Astral Plane in an invisible way was almost impossible to find.
Although there were many benefits to a Mage's Mansion, there weren't many Advanced Mages who owned one. The main reason was that this spell was too difficult.
In fact, Mage's Mansion was a low-level version of a legendary mage's demiplane. It was almost as difficult as the level-nine spell "Time Stop" among the high-level spells.
There were very few Advanced Mages who could master this spell. Most Mages would only learn this spell after advancing to Great Mage.
A Mage's Mansion was also the lowest standard of a Dimensional Merchant.
Unfortunately, this spell wasn't worth refining into a Magic Seal spell.
"Greater Teleportation" was an advanced version of Teleportation. It could teleport farther than Teleportation, but it was more accurate and had a complicated error prevention mechanism.
Because of the experience of refining Teleportation, Feng Chou used less than two years to turn this level-seven spell into a Magic Seal spell.
"Otherworldly Teleportation" was a spell that broke through the power of the boundaries between planes and sent the target to another plane. To use this spell, detailed magical data of the target plane was required. This data wasn't just a simple map, but also complicated spatial data. Otherwise, the teleportation spell would randomly throw you to any possible corner of the target plane. As for whether the environment would kill the teleporter, it was completely up to luck.
The spatial data of every safe teleportation point was extremely precious. Most of them were in the hands of Dimensional Merchants. Currently, Feng Chou didn't even have such coordinates.
Feng Chou, who had tasted the benefits of Dimensional Transactions, was very interested in this spell. He spent nearly two years turning this spell into his own Magic Seal spell.
"Phasing Gate" was a rather obscure spell that didn't have much use. Feng Chou had only dabbled with it for two weeks. After establishing a stable connection with the relevant laws, he stopped refining it.
"Banish" and "Expel" had similar advantages. The difference was that Expel could only expel creatures from other planes, while Banish could expel creatures from the prime material plane to other planes.
Banish actually made use of the prime material plane's natural rejection of creatures from other planes. The reason it could expel creatures from this world was because it used magic to deceive the world's laws, making them think that the target creature was the kind of creature the mage wanted him to be.
Therefore, Banish had another characteristic. It didn't expel creatures back to their original plane, but to the plane the mage wanted them to go to.
The advantage of Banish was that it could instantly get rid of a powerful opponent. Even if the opponent was protected by a legendary defensive spell, it could still make use of the world's laws to expel them to an unknown, distant plane in an instant.
Like Expel, Banish wasn't purely a spatial spell. In this spell, the laws of space only played a supporting role. It was used to strengthen the power of expulsion and reduce the resistance of the plane's boundary force. It occupied less than a third of the spell's length.
However, Feng Chou still spent nearly three years to forcibly refine this spell into a Magic Seal spell. This was because it was indeed a rather useful spell.
It could allow you to expel an enemy from the battlefield in an instant. It was a spell that could instantly change the situation of battle.
… …
After refining Banish, Feng Chou left the isolated deserted island and teleported back to Green Dragon Island.
In fact, Feng Chou had wanted to go back as early as last year. Unfortunately, refining Banish was at a critical juncture, so he could only postpone the plan.
Compared to six years ago, the Green Dragon Island of today had undergone a great change.
