Thinking of this, Wu Mo immediately began to prepare.
He put on the heat-insulating gloves and poured the molten iron in the crucible back into the furnace. Then, he immediately placed his hands near the fire exit and controlled the flame in the furnace to roast the molten iron.
As he injected the mental power in his mind into the furnace bit by bit, the temperature of the flame began to rise.
Soon, the color of the flame, which had exceeded 1,500 degrees, gradually changed from red to orange.
The molten iron inside slowly boiled up, and a lot of impurities were removed.
However, at this rate, it would take at least three days to remove all the impurities in the molten iron. However, Wu Mo did not have that much time to waste, so when the temperature reached 1,700 degrees, Wu Mo abruptly transferred his spirit power at a faster pace!
