The thousand-year cold iron was very rare and precious . This kind of iron originated from extremely cold places, and it carried low temperature by itself . It would require a very high temperature to melt . Thus, the control of the temperature must be very accurate . Any mistake would damage the coldness of the cold iron itself .
“The body of the Remnant Ice Sword is extremely thin . It’s a problem for us now to cool it down and forge its shape . If we place it into ice water for immediate cooling, the sudden change of temperature may break the sword . If we cool it down slowly, the shape of the sword body may be altered during the process . ”
The incharge had a very bad headache thinking about the problem . The shape of the Remnant Ice Sword had been forged earlier on . However, they could not find a way to cool it down as the body was too thin . They had dragged on for a few days now . If they continued dragging on, the special property of the ice iron might be damaged .
The body of the sword was so thin that it was extremely difficult to forge . Even the same batch of blacksmiths also could not guarantee that they could forge another one .
“Little girl, what do you think? What’s the best way to cool down the Remnant Ice Sword?” The incharge asked Ye Qingtang .
Ye Qingtang did not reply immediately .
The incharge’s question caught the blacksmiths’ attention . They turned their head to find out the person whom the incharge asked .
They thought that the person must be a senior blacksmith but…
They saw a fifteen-year-old girl standing in front of them .
Their faces changed immediately .
How much forging knowledge could a young girl know?
They only treated it as a random question and returned to their discussion .
Ye Qingtang stared at the Remnant Ice Sword for a while and said slowly, “Cold water may break it . Hot water may alter its shape . I think the frost condensate water may work . ”
“Frost condensate water?” The incharge was stunned for a moment .
The frost condensate water could not be considered as water by its properties . It was more like a thick liquid with strong adherence . It was ductile with a low temperature and could bear with high heat .
It was usually used to fill in the boxing gloves temporarily under high temperatures as it would not evaporate .
However…
He had never heard of using it to cool down weapons .
The incharge hesitated .
Ye Qingtang’s words caught the blacksmiths’ attention again . They looked towards Ye Qingtang, and their eyes were full of disagreement .
“Little girl, don’t talk when you don’t understand . How can the frost condensate water be used to cool down weapons? Are you joking?” one of the blacksmiths said unpleasantly .
Though the frost condensate water would not evaporate, its conductivity was strong . Its own temperature would increase when it was in contact with hot objects . It could not maintain a low temperature for cooling down .
The blacksmiths only treated her as a young girl who did not know anything, and her suggestion was like a joke to them .
Ye Qingtang shrugged her shoulder and did not say anything . The Remnant Ice Sword was not hers . She was just answering the incharge’s question .
The Remnant Ice Sword must be cooled down today, and no one found an appropriate method until now . The incharge looked at Ye Qingtang and said, “Little girl, how confident are you if I ask you to take over the task?”
