The Nirvana Demon Flame was kind of flame that had been formed from Nirvana Qi. However, it was several times more powerful than any ordinary Nirvana Flame.
This kind of flame was not scorching hot but it possessed an usual melting ability. Under the wrap of that flame, even the powerful Nirvana Golden Body would be melted into a puddle of blood.
Normally speaking, this kind of Nirvana Demon Flame would only appear after one experience three Nirvana Tribulation. Such a flame was born from within. If one was careless, one would be stealthy melted down by it. At that time, other people might not see any change from the outside but the interior of one’s body would likely become completely empty and one’s flesh and bones would cease to exist. It was an extremely frightening and strange fate.
