When Lu Zhiyu walked down, the bell of the tower also rang, and the students inside the tower had already gathered in the classroom, today was the time for Lu Zhiyu to go to class, and it was also the last lesson that Lu Zhiyu gave them.

The more than forty wizard apprentices who came here at the beginning, after five years, everyone has undergone earth-shaking changes, and each of them exudes the light of confidence and wisdom, which is the charm that can only bloom after having enough knowledge and strength, a beggar and a person with poor knowledge will never have such a spirit.

When Lu Zhiyu walked in, he saw everyone standing up and saluting him, Lu Zhiyu looked at everyone present, compared with five years ago, he was more mature, and the change was more in appearance, when he came, he remembered that there were many people who looked more frustrated, and now at a glance, he was full of handsome men and women, and the same as coming out of the painting.

More than forty apprentices have all exceeded the seventh scale of spiritual power, reaching the point of releasing spiritual power and becoming official wizards, and less than ten wizard apprentices have become second-level wizards, and they are basically hovering on the edge of twenty-nine scale spiritual power, while only Bol's spiritual power has broken through sixty-three and become third-level wizards.

The qualifications of these people are still carefully selected by Lu Zhiyu in the mainland, but at present, it seems that there is only one Pol who has potential, and those second-level wizards, if there are no adventures or outbursts of wisdom, there is basically nothing to look forward to, and these first-level wizards are estimated to have no possibility of becoming a third-level wizard in their lifetime, which is Bol's current achievements.

Lu Zhiyu gave them the last lesson, Lu Zhiyu rarely explained witchcraft to them or anything, at this point, the only witchcraft that they can use is low-level witchcraft, for Lu Zhiyu, just like a child's house, Lu Zhiyu has never developed this kind of low-level witchcraft, and will not focus on this, more to tell them the principle and some far-reaching basic witchcraft, by them to open their minds to create themselves.

Lu Zhiyu currently divides witchcraft into four stages, apprentice witchcraft: acting on itself, carrying out superficial body adjustment and transformation, and activating bloodline ability.

Low-level witchcraft, witchcraft used in first-level to third-level witchcraft, apprentice witchcraft: acting on oneself, carrying out superficial body adjustment and transformation, and activating bloodline ability.

Intermediate Witchcraft: Begin to get in touch with supernatural abilities, blood transplantation of mythical creatures, the manufacture of magic instruments, alchemy of life, and more.

Advanced Witchcraft: Become a mythical creature, start to contact the rules, control the rules, this kind of witchcraft, is all about the rules.

At present, they are beyond the existence of those bloodline knights, ordinary bloodline knights, and they are not their opponents in a dozen fights, but in the past five years, they have also developed a lot of low-level witchcraft.

Among them are sorcery that can be performed with the help of spellcasting materials: fireballs, flame explosions, poisonous smoke, and dead space, among others.

Among them, the dead space is a witchcraft developed by Levi, because when Lu Zhiyu said in class, the environment in which ordinary life lives live needs air, and he wants to create a large area of dead space in an instant through combustion and air extraction, and Akkad, who was proficient in alchemy at that time, developed a high-energy fuel, which happened to be used.

This kind of witchcraft is extremely terrifying, which reminds Lu Zhiyu of the cloud burst bombs and air bombs in the earth world, which can instantly kill everyone in a town and kill thousands of people, for ordinary people, it is simply irresistible, but for wizards, it is nothing, it is simply a sharp weapon to kill ordinary people.

However, Akkad could not easily make this high-energy fuel, and because it was too terrible, it was recommended by Pol to blockade it, and it was not allowed to be taught at will.

In addition, there are witchcraft that is convenient for the use of mental power: wizard's hand, spiritual charm, illusion control, spiritual detection force field, lie identification, etc., most of these witchcraft about the use of mental power were developed by Catherine and Wendy and Wolft of the elven race, who have very high talents in this area.

Then there is the sorcery of life modification and synthesis: healing, disease healing, bloodline talent awakening, Clermo's body modification, amputated limb regeneration, and memory enhancement wisdom, most of which were proposed by Pol or jointly developed with others, including his friend Uruk the pigman.

In particular, among them, the Clermo Body Transformation Technique and the Strengthening Memory Wisdom Technique, Lu Zhiyu affirmed Pol's talent in this regard, and the latter one is even comparable to the wisdom auxiliary brain technique created by Lu Zhiyu, which transforms and adjusts the structure of the brain, which can strengthen people's memory and wisdom.

And the Clermo Body Transformation Technique, which was proposed in the first class, imitates the bloodline talents of other bloodline knights and transforms them, although this witchcraft has not yet been perfected, but there are already several bloodline talent transformation techniques.

Many of the witchcraft apprentices present have learned this witchcraft, each of them has at least a few bloodline talents, and it is a more practical kind, even if they don't use witchcraft, with their physical and natural strength, they can become the strongest and top warriors on the battlefield, not to mention the various witchcraft they master that are extremely mysterious to ordinary people.

The last one is alchemy, which is still very early in its form, and the main representatives are Akkad and Pol, who are very keen on this aspect, and Pol has created a variety of healing potions, disease potions, and body modification potions, as well as his latest work, meditation potions that can assist meditation.

Akkad was born into a family of craftsmen, and most of his developments were the product of some strange mechanical alchemy, and he did not miss a single lesson in mathematics and geometry, and he was also the best in this area.

Akkad is good at purifying all kinds of metals through mental power control of flames, and with other conditions, to make various alchemy products, gunpowder and high-energy fuel are Akkadian Farmin, he made cannons, and later tried to miniaturize, made hand cannons, and even recently began to study the early muskets that Lu Zhiyu knew, but they have not yet been developed.

In addition, there are exquisite repeaters, gloves that can release thunder and lightning, mechanical puppets that require mental power to control, crystals that can glow, etc., some of which are very practical, and some of which have no effect at all, but Lu Zhiyu is very optimistic about Akkad, and even thinks that the origin of alchemy in the later stage of wizarding civilization may start from him.

Lu Zhiyu carefully observed everyone present, as this class was finished, Lu Zhiyu did not leave immediately as usual, everyone in the audience was silent and silent, everyone knew that the five-year period was up, and when they came, they were still ignorant teenagers and young men, and now they have become mature wizards.

They believe that no matter where they go, they are definitely the highest group of people, with the knowledge in their heads, with their witchcraft, if they return to the human world again, they can definitely easily stir up the storm.

Before today, each of them was looking forward to the arrival of today with joy, hoping to return to their hometown one day sooner, and stay here for five years, so that everyone had a sense of detachment from the world, as if they were locked in a cage, but when it was time to leave, they became reluctant, the wizard's tower is a temple of knowledge, a sacred place for wizards, and a place where the mentor Anthony is.
