"Buzzing ~!"


    With the coming of the fire of soul and the fire source of molten slurry, the AK47, which was originally quietly suspended in the void, trembled violently at the moment. The small ice blue scales on the surface of the gun body also began to show some signs of melting, and even faintly, a burst of whine came out.


    Obviously, this sound is the cry of the demon of the Jiuyou ice lion, which was previously integrated into the AK47. It is an evil spirit with ice cold attribute. At the moment, it is burned by two flames. Naturally, it is a situation of more or less good and less good, and constantly makes a sound of mourning.


    However, in this case, master Shi was indifferent. He took a molten fire source from the array, waved it with a big hand and wrapped a dark golden Geng essence.


    Geng Jing is the top metal in the firmament. It has the reputation of sharp gold treasure. It is used to penetrate treasure ware and can double its power in terms of sharpness.


    If in the usual burning, this extremely hard metal material needs at least five days to melt and remove impurities.


    However, at the moment, under the burning of the molten slurry fire source, the dark golden Geng essence slowly melted away at a speed visible to the naked eye, forming a dark golden liquid.


    "Hiss, hiss, hiss!"


    Long Bufan''s eyes were slightly stunned. He clearly saw that there were some gray black thick liquid that seemed to be impurities, constantly dripping from the dark golden liquid. As it fell on the floor, it immediately burned out small black holes.


    You know, the stone brick on the floor of the casting room is a very rare tool smelting material called Yuan absorbing stone. Except that it can be destroyed by the kilo force of pure flesh, the yuan force of any attribute system martial arts is invalid and extremely strong.


    However, these impurity liquids can instantly penetrate pores. It can be imagined how terrible the high-temperature heat contained in them is!


    Long Bufan sat in the corner of the casting room, his eyes blinking, staring at every refining process of master Shi,


    As a spirit talisman, long Bufan can sensitively perceive that just when smelting the Geng essence, master Shi''s soul fire was condensed into countless flame filaments, which poured into the Geng essence, changed the metal structure and hardened tissue inside the Geng essence, and then burned it to the liquid faster with the help of the molten fire source.


    This is an extremely complicated and superb skill, and only a powerful spirit caster can achieve such dexterous and subtle control.


    Bang bang!!!


    With the passage of time, the sound of violent eruption of the volcano is still heard. All the molten slurry spewed out is swallowed up by the fire system fusion array, continuously supplementing the fire source energy in the array.


    Under the gaze of long Bufan, the dark golden Geng essence, quenched at such high temperature, also kept making a "hiss" sound and quickly discharged impurities.


    Half an hour later, the dark golden heptane metal liquid was completely transformed into a viscous pure gold liquid. Neither the naked eye nor the spiritual sense could detect any residual impurities in it.


    Originally, it took five days to melt the quenched Geng essence, but now it only took half an hour. With such a huge gap in time, it can be seen that the fire source contained in the molten slurry contains extremely rich energy in this once-in-a-century volcanic eruption.
