Dr. Wilkins finished speaking and thought for a moment, and said seriously: "It's nothing to say that you two basic magics are all about the Undead system. I have been a bit involved in the Undead system a few years ago, but you should know that I am in the Energy Plastics Department. Although I have studied the Undead system, I have not learned it myself. I cannot guarantee whether I can learn it or how much I can learn it. You must know that magic is the most precise. It is a slight difference that can be missed. If you miss a syllable when chanting a spell, or a symbol when condensing a magic ring, it will lead to the failure of the magic, or the power will be greatly reduced."

"It doesn't matter. I'll admit what I can learn. Please teach me a doctor." Xu Mu answered very solemnly. If ordinary people hear this reminder, they will consider it. However, Xu Mu has a cemetery system. No matter what magic, as long as the cemetery is certified, he can use it normally.

Seeing that Xu Mu was like this, Dr. Wilkins nodded and agreed, and it was not a big deal.

However, it was impossible for him to teach magic step by step. After nodding, he only ordered the students to get two magic books from the study and hand them to Xu Mu.

"These two are all magical magic in the undead system, one is a soul-spray based on the undead mage, and the other is a bone spur technique for melee defense." Dr. Wilkins was very kind and took out two magics at a time. In addition to the soul-spray that Xu Mu urgently needed, he actually provided one, which made Xu Mu very grateful.

In fact, Dr. Wilkins also wants to take the opportunity to make a good relationship with Xu Mu, and be able to embark on the path of magic on his own. He either has extremely high talent or has another adventure and will definitely achieve extraordinary achievements in the future. He will send two irrelevant magic books today, which may bring the favor of a powerful undead mage in the future.

Xu Mu took the magic book and thanked him repeatedly, and left the top floor of the castle with Vincent with satisfaction. Then the two broke up. Xu Mu returned to the room alone and immediately closed the door and couldn't wait to open the magic book that recorded the soul-summoning technique.

Spiritual conjuring is the introductory spell of the undead magician and the basis of most undead magic. As a necromancer, the greatest combat power is the undead troops under his command. However, no matter what kind of undead creature, skeleton, zombie, or powerful black knight and skeleton dragon, the soul-summoning technique used to summon them is soul-summoning technique. However, it is enough to summon low-level undead such as skeleton soldiers, which is enough to use the ordinary version of soul-summoning technique, while summoning black knight or undead dragon, you must use the advanced spell of soul-summoning technique - spirit-summoning technique!

In fact, the undead creatures driven by the undead mage did not come out of thin air. There is still debate in the magic theory community today about the form and source of the existence of undead creatures.

It is mainly divided into two perspectives:

The first is the Void Psychology School, which believes that undead creatures are spiritual fragments in the void, driven by undead magic, and then act on real matter to form puppets with intelligence. This kind of puppet is not necessarily a skeleton or zombie, but it can also be soil, rock, steel and other substances. However, the corpse of a creature has a higher affinity for undead condensation, making the magic completeness higher and easier to use. The biggest evidence of this view is that the more alternative summoning stone demons, clay stone demons, blood stone demons, and steel stone demons. These stone demons are not biological corpses, but can be summoned as undead creatures.

The second type is the Necropolis Dharma Realm School, which believes that the undead creatures are not spiritual fragments, but exist in another world, which is generally called the Necropolis Dharma Realm. The necropolis mage uses magic to summon the undead creatures in the undead Dharma Realm and drive the undead creatures to fight through contractual relationships. This view was very popular before the Industrial Revolution, and combined with theology, giving birth to religion and worship the gods of the underworld who control the undead Dharma Realm. The more powerful evidence of this view is the existence of the undead dragon.

The undead dragon is the most powerful undead creature to date. From the first point of view, it is impossible to explain the existence of the undead dragon, and it is even more impossible to summon the undead dragon by condensing the vile energy fragments. It is necessary to use a specific sacrificial magic array to communicate the dragon's souls and recognize each other through spiritual communication to reach a summoning contract. Obviously, the undead dragon is not a undead creature temporarily condensed by the spiritual fragments, and then proves the existence of the undead Dharma Realm from the side.

Fortunately, Xu Mu didn't need to think about it so much. He had a cemetery system, such as void spirits, or the undead Dharma Realm. He only needed to increase the level of the cemetery, whether it was a high-level black knight or a undead dragon. Unlike many miserable undead mages who still had no contracts for a real high-level undead creature even if they were promoted to a magician.

Xu Mu sat in front of the desk, holding the magic book of soul-summoning in his hand and reading it carefully.

As a magical link, soul-summoning is not complicated and the difficulty is even lower than that of Xu Mu's mastery of Death Spirit Vision. In fact, normal necromancer apprentices also learn soul-summoning skills first and then death Spirit Vision. Unfortunately, Xu Mu's situation is special, which causes one after another to be reversed.

Spiritual conjuring is said to be a magic, but the magic book given by Dr. Wilkins records three magics, namely "summoning skeletons", "summoning zombies", and "summoning ghosts". The difference between the three magics is the combination of the void spirit after condensation and matter. If it is combined with the bones of a creature, it is summoning skeletons. If it is a corpse, it is summoning zombies. If it is not combined with matter, it is summoning ghosts.

"It seems that this magic book comes from a necromancer of the Void Psychology." Xu Mu knew in his heart that there were not many words in the entire magic book, but he took a lot of notes on all sides. It should be Dr. Wilkins's views and experience on this magic have given him a lot of inspiration to Xu Mu's understanding of the core of soul-summoning.

Xu Mu read the magic book several times, closed his eyes and pondered, trying to recall the content of the magic book in his mind, and then simulated the use of it, how to condense the magic rings and how to cooperate with the spells. If you find the feeling of discomfort, you will not read the magic book immediately, but will remember it silently. After half an hour, you will find three problems and read the magic book again.

Almost seven or eight hours later, Xu Mu finally learned the soul-summoning technique. When he entered the cemetery and opened the character state, he found that there was an additional soul-summoning technique lv1 in the skill column.

Xu Mu was secretly happy, but he retreated from the cemetery with some trepidation, took a deep breath, and used the soul-suming technique.

As the spiritual energy gathered in his body, a gray-white light ball began to condense on Xu Mu's hand. The light ball was very dim and was about to be extinguished at any time. However, in the gray-white light ball, a red magic ring surrounded Xu Mu's palm began to form. Xu Mu concentrated his mind and did not dare to be distracted at all. The red magic ring was finally formed intact. The next moment, suddenly, as he chanted the magic spell in a low voice, an enlarged red magic ring appeared in front of him, and a whirlpool appeared in the center of the magic ring. At the next moment, with a bang, a white skeleton arm stretched out from inside...
