"The defect was caused by this reason after all," Lin Tian realized suddenly.
As someone from an era with advanced heavy industry, Lin Tian had no trouble grasping this concept. The basic condition for metal casting was the temperature of the fire. The more special the metal, the harder it was to melt, requiring even higher temperatures.
If the metal couldn't melt, casting was out of the question. In professional terms, it was a matter of the metal's melting point.
However, Lin Tian still had questions. He asked, "That still doesn't clarify the connection between the defective golden sword and my weakness."
