Like Yang Tian's Immovable Bastion skill and Nangong Lei's Lightning Spirit Possession, Fire Leviathan was Yao Mei's most powerful skill at the moment. Also, like the two skills mentioned above, Fire Leviathan was strictly linked to Yao Mei's power in the real world.
When Yao Mei obtained her Fire Spirit class, she acquired six skills in total. Of these six skills, two of them were linked to Yao Mei's fire control and, although they were extremely powerful, they also had consequences for being used. What happened with Nangong Lei was a clear example of the possible consequences of using skills that put too much strain on the player's brain.
One of the two special skills Yao Mei obtained was Meteor Storm; this skill caused constant fire-type damage to all targets within the area affected by the meteor rain for ten seconds. The most amazing thing was that the area of effect was really wide, almost two kilometers long!
