[Five Viscera Spiritual Fire], as a type of Celestial Fire, naturally would not be simple.
This kind of spiritual fire not only possesses extreme heat but is also a treasure that assists cultivators in breaking through realms.
With the spiritual fire blazing within the Nascent Soul, it can be said to be the most suitable spiritual object for the Golden Core Great Perfection stage when breaking through to the Nascent Soul stage.
It could be said that even Golden Core Cultivators with an Earth Spiritual Root have a great chance of breaking through to the Nascent Soul stage with the aid of this type of Celestial Fire.
Milton Cheney didn't need such a spiritual object when he made his breakthrough to the Nascent Soul.
After all, his Spiritual Root was a Heavenly Spiritual Root.
Of course, he had no way to use it even if he wanted to, because he had not yet obtained this clump of Celestial Fire at that time.
