"Not enough, not enough, the flame is still too weak, the temperature can't reach the standard to melt Geng Metal."
Zhong Lin looked at the Geng Metal that was heated to a crimson red in the Pill Furnace but still showed no sign of melting. With a thought, he began to circulate the "Five Elements Mixed Essence Skill."
In an instant, a crimson flame ignited in the palm of Zhong Lin's hand.
This was the Red Flame Spirit Fire, originally a secret technique contained within the "Red Flame Technique," which Zhong Lin later integrated into the "Five Elements Mixed Essence Skill." With the circulation of Spiritual Origin, it was easily summoned.
With the addition of the Red Flame Spirit Fire, the temperature of the flame began to soar once again, and there were finally signs of the Geng Metal Iron Ingots melting.
