"Understand, please master Lin." long Bufan nodded. Like alchemy, there is a failure rate, which he can understand.


    Although the failure rate of 10% is already a very good probability, it also makes long Bufan a little nervous. However, compared with the failure rate of more than 70% of other middle and low-level spiritual casters, he still feels to spend more money and feel at ease.


    "Hoo --!"


    Long Bufan took a deep breath and sat cross legged on the spot. The evil sword is very important to him, and the people are separated from the belly, so he doesn''t intend to leave for half a step in these two days!


    "Zhizhi ~" Xiaobai also jumped from long Bufan''s shoulder to the side and lay down lazily against long Bufan''s side. The temperature of the casting room makes it feel very warm.


    Seeing that the young man longbufan chose to stay here, master Lin just glanced at longbufan, didn''t say much, and then carried the materials to a tripod furnace on the inside.


    Looking at master Lin who was about to start work, long Bufan prayed silently in his heart: "we must succeed..."


    "Hiss ~!"


    Then, master Lin waved his big hand, and the evil sword with black awn suddenly floated in the air. At the same time, in his sharp eyes, two groups of strange purple awns flashed, which immediately penetrated his eyes and burst out, condensing into a purple flame in front of him.


    "Fire of soul!"


    Long Bufan looked at the dark purple flame suddenly condensed in front of master Lin, and his heart was shocked. He understood that this is the soul fire that can be displayed by the spirit caster. It is a powerful flame that can be produced only after the spiritual power is condensed to the extreme. Its blazing temperature is comparable to that of the fire essence.


    The main reason why the spirit caster is far more than the ordinary tool refiner is that he can condense this kind of soul fire. Even the hardest things can melt instantly.


    Moreover, in the face of the attack of this soul fire, Rao is a martial arts practitioner who has reached the Shenhai territory, and he does not dare to make a hard connection. After all, this is a terrible flame that even the yuan God can burn and erode. If the yuan God is injured, it will be an extremely serious sequelae for the martial arts practitioner and have a great impact on the martial arts in the future.


    After sacrificing the fire of the soul, master Lin''s expression was gradually dignified. Then, when the sleeve robe was waved, the fire of the soul diffused and opened, just like the virtual shadow of a fire beast, and swallowed the spirit devouring evil sword suspended in the void in an instant.


    "Buzzing!"


    The spirit devouring evil sword suddenly trembled violently under the package of soul fire, and sent out bursts of sword chanting.


    In this case, master Lin looked calm and unhurried. He took out a dark golden iron essence from the nearby pile of materials. Immediately, his eyes stared, a fire of soul came out again, and wrapped the iron essence the size of a brain fist.


    "Hiss, hiss!!!"


    The hard and incomparable iron essence melted gradually at a speed visible to the naked eye under the burning of the soul fire. Some gray and black impurities were eliminated and dropped on the floor under master Lin''s spiritual knowledge, and immediately corroded into small holes.


    It is conceivable that the temperature has reached a terrible height.


    Long Bufan, sitting beside the door of the casting room, stared at each refining process of master Lin in surprise. He could see that while smelting the iron essence, master Lin''s spiritual power was transformed into thousands of spiritual filaments, which poured into the iron essence and changed the hardened organization of the internal structure.


    This is an extremely complex and superb skill, and only a senior spiritual caster with strong dexterity can achieve such dexterous control.
