The exertion of the field will consume its own strength, including the strength of the whole body, as well as the strength of the body.


    However, the consumption is not much. Every strong person in the field can expand the field for a long time.


    However, if the field is expanded and the strength of the field is used again and again, the consumption of strength will be accelerated.


    Well, for example, when you cast the art of domain shock, each cast will consume part of your power. After multiple casts, if the power is insufficient, the domain will automatically disintegrate and disappear, but it will not disappear forever. When the power is restored, the domain can naturally be used again.


    Before, the skeleton swordsman used the technique of concussion in the field for many times, and used the technique of chopping in the field again, which consumed a lot of power. At once, he was traumatized, so that the power operation was not as smooth as before. Under the influence of various aspects, coupled with Tang fan, he first used the claw of bones, deliberately causing the other party to use the technique of concussion in the field.


    The casting of the art of domain shock can''t last all the time. It''s like a skill. After casting, you need a buffer time to cast it again.


    When the skeleton swordsman performed the art of field shock and disintegrated the claw of white bone, Tang fan seized the buffer opportunity and quickly approached the field. In a moment, the skeleton swordsman had disintegrated because of the sluggish field of power flow.


    Without the protection of the field, Tang fan approached again, and the technique of field concussion went away again, directly breaking the bones of the other half of the skeleton swordsman''s body.


    "White bone claw!"


    Suddenly, the white bone claws appeared and fell again.


    This time, the skeleton swordsman with only one head could not resist and was directly caught by the white bone claw.


    Tang fan''s thought moved. The White Bone Claw trembled and bloomed a pale luster. Then, it shrank miraculously and finally became a bone claw thicker than the human arm. It just grabbed the skeleton head of the skeleton swordsman in his hand and squeezed it.


    With a click, the skeleton swordsman''s skull broke.


    Bone fragments scattered from the gaps of the white bone claws. When the white bone claws spread out, we saw a dark purple gray soul fire burning and swaying on the white bone claws.


    Immediately, the flame became smaller and smaller, and gradually contracted, revealing a dark purple gray crystal thick and thin on the thumb finger.


    Tang fan can feel a strange power from the dark purple gray crystal. It seems that there are fluctuations in the power of the soul and other power fluctuations. In a word, it is a mixed power fluctuation.


    Under Tang fan''s gaze, the attribute of this dark purple gray crystal also appeared in Tang fan''s mind.


    "Soul crystallization: after understanding the field, the soul origin of the strong will change qualitatively and form a crystal. The crystal contains the pure power of the field origin, which can absorb and improve its own field power. Quality: second order."


    The attributes in his mind made Tang fan stunned first and then happy.


    "It''s such a good thing." Tang fan quickly grasped the crystallization of his soul in his hand. In a moment, the claws of white bones disintegrated into countless white dots.


    Originally, Tang fan was still thinking that he had understood the field, but it was only the first level, and the field seemed to have ten levels. When the tenth level was perfect, he could completely master the field.


    However, before, I was able to improve my spiritual power through the absorption, purification and absorption of soul power, so that I can quickly become strong.


    However, after understanding the field, the spiritual power has reached the limit. Even if you absorb more soul power, you can''t make any progress in the spiritual power. Everything is transformed into the mastery of the field.


    Tang fan is completely unfamiliar with the field, and he doesn''t know how to quickly improve his mastery of the field. You know, for example, iopalas and Robert, it took them decades and hundreds of years to master the first-order field.


    Unexpectedly, there is such a thing as soul crystallization, which contains the original force of the field, which can be used to absorb and accelerate the mastery of the field.


    Tang fan can''t wait to absorb the power of this soul crystallization, but he doesn''t know how to start.


    "Master, maybe you can expand your field and wrap this soul crystal with your field strength." Derek appeared at the right time and suggested.


    Tang fan thought a little, it seemed feasible. The field expanded again and directly wrapped the soul crystal.


    In an instant, the soul crystallized and broken, and a pure source force of the field spread out, as if volatilized into gas. Tang fan felt that his field seemed to be absorbing this force and strengthening it a little bit, and the silver gray silk thread seemed to increase a little.


    This absorption took about a minute to complete. Tang fan felt that his field strength had increased again, about one tenth.


    "In other words, I still need to absorb nine second-order soul crystals before I can raise my field to the second-order level." Tang Fan said to himself: "if it is a first-order soul crystal, I don''t know how many pieces it needs."


    "Yes, master, you will strive for the crystallization of your soul in the future," Derek said with a strange smile.


    Tang fan feels that this is indeed the case. In the future, the strong in the field can no longer attract Tang fan''s interest. Only by mastering the strong in the field can Tang fan arouse his desire to hunt.


    "By the way, since I can absorb soul crystallization to improve the level of my field, IO Palas and Peter should also do so. As long as there are enough soul crystallization, we can rapidly improve the level of our field." Tang fan''s eyes brightened and thought.


    Then, Tang fan quickly flew back to the outside of the skeleton city. Augustone had fallen the skeleton Legion and completely killed the other''s skeleton legion, and IO Palas and Peter returned to the team again.


    This intermediate skeleton city has belonged to Tang fan since then.


    However, Tang fan''s goal is not here. Therefore, this intermediate skeleton city is only a turning point for Tang fan in the end, a transitional place and a temporary point for Tang fan to temporarily accumulate strength and set out again.


    The order was issued. Soon, everyone took action. The skeleton city was renamed the eternal city again. The news of recruitment spread again. Augustone also quickly strengthened the training of the skeleton Corps. Everything was prepared for the next expedition, because Tang fan''s goal was the advanced skeleton city. (to be continued.
