Although Locke is in the Loki plane, his soul has long been branded with the undead plane. Locke was able to sense the connection between his soul fire and the undead plane, and as long as he communicated the connection with the soul of the undead plane a little, it would not take a few minutes for Locke to return to the undead plane.

Therefore, when Locke faces a desperate situation, the undead plane will also be Locke's retreat.

And now, when Locke saw the undead summoning this undead magic in the necromancer's codex, a new idea arose, maybe he didn't need to return to the necromancer realm, he could improve the soul fire in the Loki plane and promote to a higher-level skeleton creature, instead of purely refining the bone essence of the strong to improve his bone strength.

Determined to learn the magic of summoning the undead, Locke also put all his mind on these pages of the Codex.

First of all, of course, is the introduction of undead summoning magic.

As a highly applicable necromancer, there are pages of information about undead summoning magic. There are even various derivative necromantic spells summoned by the undead, which can summon some specific undead creatures. Changing the spell a little bit and paying a bigger price is that you can only summon undead creatures that suit your needs.

And the undead summoning, as well as advanced magic, can directly communicate with the undead plane through a large number of corpses to summon a large number of undead creatures at one time, which is the terrifying place of necromancers, this advanced magic has another name, called the undead disaster.

Necromancer summoning is a necromancer who summons creatures from the undead plane to fight for himself through the spell of undead summoning magic.

Generally speaking, necromancers can summon undead creatures that are lower than themselves or at the same level as themselves, and it is difficult to summon undead creatures of higher level than themselves without the help of alchemy potions, magic scrolls, and magic items.

Whether it is the derivative magic summoned by the undead or the advanced magic, it is not suitable for Locke's research at this time.

Although Locke has been able to study and learn its derivative magic, its consumption is much greater than that of the undead summoning of the same level, and even if Locke masters it, the success rate of casting it will be extremely low.

As for the advanced necromancer, Locke at this time did not even have the qualifications to study, the undead calamity, it is difficult for ordinary seventh- or eighth-level high-level necromancers to perform it without the help of props, and only some ninth-level necromancers can cast it freely.

And once a ninth-level necromancer casts a necromancer, he will be able to compete with the weaker Sanctuary as a ninth-level mage, which shows the horror of the necromancer. You must know that under the Holy Domain, there are still many strong people who can challenge the level with the help of equipment and combat skills, but it is almost impossible for a ninth-level professional to challenge the strong people in the Holy Domain.

The author of this mage's codex, Kaneski, is an existence who can leapfrog and challenge the powerhouses of the Sanctuary. Of course, although it has a strong strength comparable to the weakest Sanctuary powerhouse, but its luck is still a little worse, and the object of the challenge is slightly stronger than the Sanctuary it can challenge, and it can only fall completely, leaving only a few powerful undead magic items and this mage codex.

After roughly skimming through the pages of records about the summoning of the undead, Locke naturally turned his mind to the simplest summoning of the undead.

The spells summoned by the undead are also quite complex, at least much more complex than undead magic such as bone spear shooting, and to cast them, you need to establish a connection with the undead plane first.

Of course, those who can study magic can't be intellectually deficient. The intelligence of ordinary humans on the Loki plane, when placed on the undead plane, is also equivalent to the intelligence of lord-level or close to lord-level existence. Therefore, even if the spells of necromancy are complex, as long as the necromancer's magic and mental power are sufficient, he can still study and learn.

And those ordinary middle and low-level undead creatures want to study undead magic, in addition to talent, intelligence is also a major factor. Locke is a high-achieving student from the earth, and in terms of intelligence, he is only higher than ordinary humans in the Loki plane, and naturally there will be no wisdom problems when studying necromancy.

It only took ten minutes for Locke to memorize the magic spell summoned by the undead in his mind, and Locke also remembered some of the points of attention for researching and casting.

First of all, Locke needs to establish contact with the undead plane, communicate with the undead plane, or locate the coordinates of the undead plane. Without the slightest difficulty, Locke easily mastered the first step of casting the summoning of the undead.

To know the Dao, many necromancers need to spend a day or even days on this step.

After completing this condition, Locke naturally needs to chant a magic spell and directly release the undead to summon magic.

As soon as his mind moved, Locke used the soul fire directly in his mind to chant the magic spell summoned by the undead.

As Locke chanted, Locke's spiritual power began to slowly consume. However, the undead magic power in Locke's body did not decrease in the slightest, and no undead creature appeared, and Locke knew that his first spell must have failed.

However, the failure of the spell was also expected by Locke, even if the genius happened, the chance of the success of the first cast was very small, and if it was not accidental, it basically would not appear.

Despite the failure of the spell, Locke sensed that his mental power had been depleted a little. Locke found that he was studying the cost of using the undead to summon mental power much faster than he had studied the techniques of weakness and retardation in the undead plane.

And just like that, hours passed in a flash. To Locke's disappointment, his undead summoning magic was unsuccessful once. And Locke's spiritual power was also consumed in the soul fire chanting spell casting again and again, and it was about to bottom out.

This is different from what is written in the Magic Codex. It is important to know that for a necromancer who has not been in contact with necromancer magic for a long time, it may be difficult to complete the spell of undead summoning, and it will take a certain amount of time. And Locke is not a low-level necromancer, but a fifth-level necromancer, and he has not succeeded in casting the undead summoning, which naturally surprised Locke.

Undead summoning is a direct communication between the undead plane to summon undead creatures from the undead plane. The lower the level of the undead creature summoned, the less mana and mental power it needs to consume, and the higher the chance of a successful summoning. As a mid-level necromancer, Locke should summon a low-level undead creature without hindrance.

After performing it hundreds of times in a row and ending in failure, Locke couldn't help but be a little discouraged. Although the spiritual power consumed by the failed spell casting is not much, but the number of times is too much, the consumption is still very high for Locke.

Locke Zhilu said, with the spiritual power he still has preserved, he casts the spell several times again, and he must stop researching, and he needs to rely on meditation to recover his spiritual power before he can continue to study.

Picking up the necromancer's magic codex again to see if there were any points he had missed, Locke found that his spells and steps were not in the slightest.

Under such circumstances, Locke couldn't help but start thinking about what the problem was. As a necromancer, apart from encountering other necromancers, he has no opportunity to exchange magic research experiences with other mages, otherwise he will be hunted down by the church and a large number of nobles.

"Is it because I'm an undead creature that I can't release the undead summon like other human necromancers? Locke couldn't help but think about the possibilities.

Inadvertently, Locke couldn't help but think of the time when his sister Rowling released water magic at noon. In my memory, every time my sister whispered a spell, a water magic would attack her. Even though Rowling was only a low-level water mage, she had a nearly eighty percent chance of casting a spell after chanting it.

Locke kept recalling how he had used his necromantic magic, comparing it with his sister, hoping to see if there was any difference other than his identity as an undead creature.
