Chapter 629: Consumable Demon Vessel

[Fire Qilin Scale (Consumable Demon Vessel):

[When you add it into the refinement process, you can ensure that the temperature of the flames will be at a stable level. It is a gentle medicine, and it increases the success rate of refinement. In fact, even when the flames in the furnace are extinguished, it will ensure that the weapon will be unharmed and that the heat around the weapon remains at scorching temperatures.] 

The description of Fire Qilin Scale was very detailed, but in conclusion, adding the scale during the refinement process was the same as having an unseen spirit watching over it. There was just no possibility of failing. 

The scale could allow a third-echelon weapon to be upgraded to a fourth-echelon weapon with one hundred percent certainty!
