The temperature of the flame, when reaching a thousand degrees and above, makes every single degree increase extremely difficult.
There were Pill Masters who, in order to refine some high melting point materials, tried every possible method. Experienced Pill Masters all know that flame temperatures are divided into several levels.
Below two hundred degrees is called low temperature. Above two hundred degrees, but below seven hundred degrees, is called medium temperature.
Above seven hundred degrees can be considered high temperature.
If it reaches a thousand degrees, it can almost refine all Alchemy materials. As for 1,500 degrees, it is enough to burn even a Sword Saint to death. Even the hardest to refine materials, such as Meteorite Iron and Ink stone, can be refined.
At this critical moment, the advancement of the Abnormal Fire to third-grade really helped Chu Feng a lot.
