Chapter 195: bronze sword embryo

& lt; remove impurities! Master, what should I do? &”Asked Luo Yu.

&”As a teacher, here is a piece of ordinary material, bronze and iron essence! Try to make a bronze sword with this bronze iron essence. Now I'll teach you how to remove impurities from it.

&”Mm-hmm.

& lt; to cast swords, preheat the melting furnace first & gt; haolao Dao

Luo Yu nodded, raised Lei Yan beast fire in his hand, and put his hand on the wall of the furnace. Lei Yan beast fire was absorbed by the red copper furnace. After the fist size beast fire was inhaled by the red copper furnace, it turned into a raging fire in the furnace with the blessing of the inscription.

This is one of the functions of the melting furnace, which is to strengthen the flame of the fire controller and save energy when melting. Haolao's nine flame is separated from the furnace, and he only needs to control the ordinary weapons with his divine sense, which is very convenient

the preheating of the melting furnace is to prevent the danger of furnace explosion when the temperature rises suddenly.

After the Leiyan beast fire in the real red copper furnace burned for a moment, Hao threw the bronze iron essence into the melting furnace & lt; you first try to find the melting point of the bronze iron essence, and then keep the constant temperature & gt;

& lt; HMM, I know! &Quot;

Luo Yu nodded and practiced the mental method of swallowing and refining the body. He controlled the temperature of Lei Yan beast fire by mobilizing the Lei Yan beast fire in his body. The temperature of Lei Yan beast fire gradually increased, and the Lei Yan beast fire in the melting furnace wrapped up the bronze and iron essence and burned.

The high temperature inside the melting furnace is frightening, reaching several thousand degrees, but there is only a slight heat outside the melting furnace. The wall outside the melting furnace is only slightly warm and not hot at all. This is the second function of the melting furnace. These magical functions come from various inscriptions with unpredictable power.

The temperature in the furnace is getting higher and higher. Twenty minutes later, the bronze iron essence gradually begins to melt. After a while, it will completely melt into liquid. Luoyu also slowly reduces the temperature of the flame in the furnace and keeps it at a constant temperature.

&”Very good. Now heat up slowly. Remember, heat up slowly. When the impurities are found to be burned and evaporated, keep that temperature. If the temperature rises, the refined melting liquid of Taiyuan bronze iron will be burned.”; Haolao said

Luo Yu did what haolao said, and gradually raised the temperature of Leiyan beast fire. When the temperature rose to a certain level, the melting liquid of bronze iron essence emitted a trace of black smoke, which were the impurities contained in bronze iron essence. At this time, Luo Yu also kept the temperature at this level.

The impurities in the molten bronze were burned and evaporated, and the volume of the molten bronze was also slowly decreasing. After half an hour, the refined molten bronze iron was one-third of its original volume in an instant.

&”It's almost done. Cool down, then turn off the engine, and then melt it. The material will be discarded.”.

Luo Yu slowly lowered the temperature of the flame, and then took back the Leiyan beast fire. After the bronze melt cooled down, it slowly solidified into an irregular red iron block.

Old Hao waved, and the bronze iron essence was taken out by a force.

&”Well, it's true that 80% of the impurities were removed in the first melting and refining. You really have the talent of a caster & “ Hao said with a smile.

&”Haha, it's all the master's good command.” Luo Yu, with a smile, dare not be proud.

&”OK, now let's start the second step, forging. As it's just to make a pure bronze sword, there's no need to melt other materials & “
