The Fifth Elder took a cold breath. Given this effect, it could be claimed that the Pure Yang True Fire ranks first among the 108 types of True Fire.
The functions of the 108 types of True Fire vary. Some fires are weak, unable to even burn mortals, but have significant efficacy in burning spaces; some are powerful but hard to control and are likely to explode; others do not burn the body but only the soul. For these reasons, it is hard to differentiate the various types of True Fire, let alone rank them as first or second.
But if you claim that your True Fire can invigorate Yang...
No one else dares to assert this, the Fifth Elder would cast a vote for Pure Yang True Fire.
"I'll research to see if your Pure Yang True Fire can be stabilized into a Fire Seed."
"Also, I'll research your Three Flavored True Fire."
The Fifth Elder took the True Fires from Lu Yang and Meng Jingzhou, planning to create Fire Seeds that can burn continuously.
