The top of the library is engraved with complex alchemy inscriptions, and the surrounding walls are inlaid with fist sized night pearls for lighting.

    Rows of bookshelves are neatly placed in the library, which makes it an illusion to come to the university library. In fact, this is indeed the library in MEL city.

    Fang Cheng walked around at will, looking at the neat wizard books on the bookshelf, excited.

    "Wizard origin, soul theory, basic theory of alchemy, basic theory of pharmacy, spell model, simple spell scroll making..."

    Fang Cheng said.

    "Just this one." He stopped and pulled out a book, which was the soul theory Phil had recommended to him.

    Fang Chenggang opened his books, and a huge data stream poured into his sea of consciousness.

    "Drop, strange data stream detected, enter or not."

    The voice of intelligent learning machine sounded in my mind.

    "Enter." Fang Cheng ordered.

    "Drop, input completed." As the voice fell, a book called soul theory was added to the database of the intelligent learning machine.

    Fang Cheng was not in a hurry to enter other books and looked at this book carefully.

    The soul is the foundation of all living creatures.

    The preface of the soul theory records such a sentence. Fang Cheng continued to read it. When the soul is weak, people can''t feel their spiritual power. They only have consciousness. Weaker creatures don''t even have basic consciousness, such as ordinary plants.

    Fang Cheng nodded and continued to look.

    The existence of consciousness is the embodiment of weak spiritual power. In other words, spiritual power is strong consciousness, and spiritual power and consciousness are the external embodiment of the soul. The soul is the foundation, and the spiritual force is the external embodiment.

    The soul theory summarizes this sentence.

    Fang Cheng suddenly felt enlightened. Think about it carefully. It''s true. He used to control the intelligent learning machine with consciousness, but now he can control it with mental power.

    It turns out that the two are integrated. Spiritual power is consciousness, and consciousness is the weakened spiritual power. In this way, everyone has spiritual power, but the spiritual power of ordinary people is too weak, which can only extend to a distance of a few meters outside the body, and the induction is very vague.

    People often have this feeling. When a person stands behind you, you can "feel" it. This feeling is actually the feedback after your conscious contact, but because ordinary people''s consciousness is too weak, the induction is very vague.

    If you change to a wizard apprentice, you can not only feel the people behind you, but also see him clearly all over his body.

    This is the difference between mental power and consciousness. It is essentially the same, but the intensity is different.

    Fang Cheng showed an interested expression. Interestingly, on earth, human beings have not even studied and cleared their consciousness. It is unexpected that wizard civilization has studied the soul so thoroughly.

    Fang Cheng continues to watch.

    With the continuous enhancement of spiritual power, ordinary people will transform their soul after reaching a limit. This transformed state is called wizard apprentice.

    It turns out that the biggest difference between a wizard apprentice and an ordinary person is that Fang Cheng nods in his soul.

    The meditation of witches, the construction of magic runes, including the taking of witches'' potions, are all to enhance spiritual power, so as to achieve the goal of ultimate soul transformation. The second threshold of soul transformation is when witches'' apprentices transform into formal witches.

    The later the soul changes, the more difficult it is. But every change will bring new life to the person who changes.

    Later, various secrets of the soul and various applications of spiritual power are introduced in detail. Although Fang Cheng did not become a wizard apprentice at this time, his spiritual power has far exceeded that of ordinary people.

    For example, Fang Chengcheng has easily learned the spiritual exploration skills introduced in the soul theory.

    Consciousness is a weak spiritual force, spiritual force is a strong consciousness, and the soul is the foundation. If the spiritual force is increased to the limit, the soul will degenerate.

    This is the subject overview of soul theory. The system of wizard civilization is based on the soul theory.

    In other words, the soul theory has the same significance for wizard civilization as Newton''s first law and second law on earth have for modern physics. It is the most basic foundation theory.

    Although simple, it is extremely important, which is the basis of wizard civilization.

    Fang Cheng now knows that the earth civilization is more inclined to foreign objects, while the wizard civilization is more inclined to itself.

    Although, as far as we are concerned, it is not easy to make a conclusion about who is stronger or weaker. However, at the same time, wizard civilization is definitely not the opponent of earth civilization. However, the development time of Earth Science and technology civilization is too short. Until now, it is only a few hundred years.

    But what about wizard civilization? It can''t be verified. It can only be described as having developed for countless years.

    Hundreds of years of earth technology and the destructive power of the strongest weapons made by human beings on earth have been enough to easily destroy a city, but what about Wizards? Although Fang Cheng doesn''t know how strong the official wizard is, he still hasn''t been so fierce.

    So, can''t wizard civilization compare with scientific and technological civilization?

    Everything about wizard civilization is ultimately for its own service. In the final analysis, pharmacy, alchemy, alchemy materials, curse, spell models, all kinds of knowledge and means are secondary.

    For wizards, the most important thing is the transformation of their own soul, which has never changed.

    Endless life and invincible power are what wizards pursue. Other foreign objects are just means to serve this purpose.

    It''s hard to judge whether the two civilizations are better or worse. However, wizard civilization obviously opens another direction for earth civilization.

    The direction of development.

    Thinking of this, Fang Cheng madly entered the knowledge in the library into the database. Each book in the library applied a special spell. As long as you open it, you can directly instill the knowledge into the sea of consciousness.

    Ordinary wizard apprentices pick up at most two books every time they enter the library, and the sea of consciousness will be filled with them, which makes them feel dizzy.

    But Fang Cheng is different. These knowledge only passes through his sea of consciousness, and then all are entered into the database. Therefore, Fang Cheng keeps turning over and looking at books without any difficulty.

    Fortunately, there was no one in the library at this time, otherwise I would be stunned.

    I haven''t seen such a terrible person. Aren''t you afraid of the explosion of consciousness and directly become dementia?
