After the Geng refining was completed, master Shi stretched out his thick palm, released his spiritual power, controlled the pure gold liquid refined by Geng essence, quickly patted it on AK47, and then painted it on the gun body with a big hand.


    "Hiss, hiss!!!"


    As the pure gold liquid was applied to the AK47, the AK47 trembled violently and emitted wisps of white smoke.


    Under the pressure of master Shi''s soul fire, the Geng * * bodies on the surface were tightly adhered to the gun body, so that the AK47 surface, which was originally a molten slurry fire source and burned as black as ink, was gradually added with golden lines. It seemed that the whole body of the gun had become thicker.


    After the completion of this process, long Bufan saw that master Shi was doing the same again and began to harden the next materials such as blood silver, obsidian, fire molten crystal and so on.


    For master Shi''s repeated refining processes, long Bufan did not feel bored at all. Instead, he was interested and watched without blinking. Like a diligent and studious refining apprentice, he recorded all master Shi''s subtle manipulation and the changing hand movements of Rune printing formula in his eyes and mind.


    Long Bufan''s cheating is obviously intended to show his skills in the future if he can''t find the master of weapon refining. Of course, even if it cannot be implemented, it is useless to learn more.


    As the sky gradually darkened, this non-stop quenching process lasted nearly two hours. During this period, master Shi''s rough face didn''t show any fatigue.


    Long Bufan didn''t Marvel too much at this. He knew that master Shi, whose cultivation reached the half step divine realm, would not have much impact on his physical strength even if he didn''t sleep for half a month. His strong body was enough to support the consumption that ordinary people couldn''t bear.


    Pa -!


    With a light sound, the top-level material melted by the last fire was also melted into liquid by master Shi and adhered to AK47.


    Long Bufan''s eyes were slightly frozen. He saw that the AK47 at this time was very different from the previous ice blue. The color of the gun was slightly colorful due to the adhesion of four materials, which was not fully refined and integrated.


    "Hoo ~."


    Master Shi also breathed a sigh of relief when he successfully quenched the four materials. At least there was no mistake in the preliminary preparation process. Next, he integrated them all.


    The reason why we use these metal liquids is that the material of AK47 itself is too low-grade. It is only refined and cast with some iron. If the demon of Jiuyou ice lion is not integrated into AK47, it can not achieve the power of dragon Bufan when he attacked master Shi with AK47.


    Seeing that master Shi seemed to stop to have a rest for a while, long Bufan asked curiously, "master Shi, what are the uses of these four materials?"


    Master Shi looked at the Dragon extraordinary, and his eyes seemed to despise him. He said faintly: "although your weapon is strange and powerful, one thing is a failure, that is, you used a low-level iron essence, which greatly reduced its real potential."


    After hearing this, long Bufan scratched his head and smiled. He didn''t refute anything. In fact, he also had difficulties. When he first established the storm territory, all kinds of expenses needed a large amount of capital turnover. At that time, his cultivation was low and he didn''t know how to smelt. He casually found some low-level iron essence to refine and cast, but he was also embarrassed by the enemies who fought in the same realm.
