Henrick did nothing except for watching what his half master was doing with full focus fearing that he might miss something important.
However, so far he didn't feel any of the steps hard. To be honest he felt simple and easy and he could refine a weapon within his first attempt.
"After pouring the molten metal into the mould, allow it to naturally cool for some time," Alaster waited for a few moments before placing his hands on the mould with his eyes closed as he continued saying, "Now, comes the most important thing in the common process to forge a weapon."
All of a sudden, Henrick could sense his surroundings become a little tense for some reason; however, that change in his surroundings only made him pay even more attention to what Alaster was doing.
'Huh?'
Soon, Henrick noticed there was some movement in the mould as though his half master was making it and that made him puzzled; however, he didn't disturb his half master as he waited for Alaster to explain what was happening inside the mould.
"Once you are at this stage, you should be able to see the inside of the mould and you have to use your physical strength in a any way that all the impurities inside the metal should come to the surface of the product,"
Alaster continuously changed the places where he was keeping his hands on the mould.
Even though it appeared that he was snot using any force, Henrik could now understand why there was a sudden change in his surroundings earlier because Alaster was actually using the force much greater force which could not be seen but only felt.
"Later, the impurities will be absorbed by the sand," After finishing that line, Alasted retracted his hands and didn't place on the mould any more as he turned to look at Henrick before asking, "So, until now, do you have any doubts?"
"Huh? Is it over already?"
Henrick unconsciously asked as he looked at the mould on the table.
"Nope. The actual process starts after a few moments from now on. So, before that, do you have any doubts?"
Alaster shook his head as he asked whether he had any doubts about the process till now.
"I have two doubts,"
Henrick didn't think much as he directly replied to Alaster because he had already planned to ask about them after Alaster finished his refining process.
'Only two?'
Alaster raised his brows after hearing Henrick's words; nevertheless, he asked, "What are they?"
According to Alaster, any cultivator that watches the weapon refining for the first time would get many doubts. So, when Henrick said he only had two questions, Alaster felt Henrick was not paying attention to him.
"How can I see the molten metal inside the mould as my cultivation is still low," Henrick didn't feel anything as he continued asking his second doubts, "Moreover, how can the sand mould absorb the impurities from the metal?"
'Common questions,'
Alaster silently thought in his head as he answered, "Foro both of your questions, there is only one answer and it is that sand is not normal sand."
"Then?"
Looking at the sand at the corner of the weapon refining room, Henrick asked his master with a frown on his face.
From the appearance, the sand looked just like normal sand in appearance.
"Yes. This sand is called 'Forging sand'," Alaster revealed a slight smile on his face as he explained, "Even though there are various manual forging techniques using the hammer, with the help of Forging sand, you can replace the hammering and other commonly used tools. Moreover, this sand helps us to connect with the metal inside it. So, what do you think?"
Alaster revealed a proud look on his face as he explained about the Forging sand.
"Th..this is excellent. I mean very good,"
Henrick didn't know what he was thinking while replying to Alaster as he thought something else in his mind, 'This forging technique looks similar to 'Purification with the thought'. Is this method derived from that method or vice versa.'
He related Alaster's forging technique to the refinement technique he learned from the projection inside the inheritance building. Both the techniques look almost the same except for using external fire and forging sane in the place of his internal fire energy.
"Now, it is very important for you to take out the product you refined inside the mould without any damage. For that, you need to be very focused and careful,"
Alaster turned very serious at the last step of the weapon refining as he slowly made a hole using the heat from his internal fire energy.
Although he could produce his internal fire energy outside his body, for the sake of Henrick, Alaster only used the heat of his internal fire energy.
'Huh?'
Surprisingly when Alaster did that, the fine particles of the forging sand separated on its own at a specific temperature and allowed Alaster to take out a perfectly refined longsword from the mould.
"When you touch the refined weapon, you need to protect your head with your internal fire energy; otherwise, you will know what will happen, right?"
As soon as he took out the weapon from the mould, he casually threw the sword into a water tub.
'Sizz'
Soon, vapours started coming out of the water tub cooling down the weapon.
"Also, this water is also not regular water. In this water, many low-level spirit stones are dissolved,"
Walking to the water tub, Alaster slowly took out the sword from the water while explaining about it.
Henrick nodded his head as he looked at the sword in Alaster's hands and became excited.
From the look anyone could say that it was a rank 1 weapon because Alaster didn't use any special materials; instead, he used only a single low-quality metal to refine.
'This sword gives me a terrifying aura from it,'
Henrick silently muttered in his head when he looked at the rank 1 sword.
"Did you understand? Or do I need to repeat this refinement process one more time?"
Alaster felt that Henrick didn't understand the whole process; however, he still asked and prepared to repeat the process one more time for Henrick's sake.
'Even my master forged 5 times before I was able to understand something and after that, I took nearly 10 refinements for successfully refining a weapon,'
Alaster could understand the problem with refinement. So, he was not strict that his disciple should learn everything at a single glance. If there was something wrong, he could repeat the process many times.
"I understood everything, Master,"
Henrick revealed a smile as he nodded his head.
"Okay then...I will repeat….Huh? What did you say?"
Alaster was mentally prepared that Henrick would ask him to repeat the process one more time. So, he was about to repeat the process one more time; however, when he recalled his words, he didn't even finish his words due to shock as he asked Henrick one more time.
"Yes, master. I understood everything,"
Henrick nodded his head as he was too excited to try the technique that his master had just used and compare this experience with how he felt when refining using his pure internal fire energy.
