Chapter 1275 'Children' part 4
The Sea of Life, it nurtures and gives birth to life so it is not allowed to be disturbed and cause 'harm'. Even Tiamat herself was only allowed to fill it until the boundaries of the land because anything further is antithetical to its existence.
The sea is where it originated and the land is where it would end before it could return to the sea.
The Sea of Life's ability to produce life is undoubtedly a form of miracle, but to freely use this miracle, it has to abide by its own rules. Such is an authority. An authority is only imposed if the foundation of its concept is adhered to.
Of course, there are exceptions. It could be used at smaller scales even if not all the conditions are met like what Kisuke did to reverse Kirio Hikifune's ability.
But in this case, no matter how chaotic the battlefield had become, the Sea of Life had remained mostly still with the waves rising only a few feet high.
[So how is she doing this?] Benihime asked while watching Sona raise the sea and usher in a sight that could only be described as a biblical apocalypse. The 'sea floor' under Kisuke's feet became visible and the black mud slowly rose up, 5, 10, 15, 20 miles up.
And just like how the insects would forever disappear the moment they fell into the sea, all those who were gobbled up, without being able to fight back were swept away and were forever incorporated with the black mud.
"Well, it's probably thanks to the other late lady." Kisuke briefly answered Benihime's question.
Benihime didn't really understand but thankfully, Tiamat supplemented Kisuke's answer, [Hestia, one of the first few Deities that were born from Null with my help. She inherited the 'nurturing' aspect from both of us. Through countless years, that 'nurturing' aspect gained an identity of its own which became known as the [Hearth's Flame]. Just like the name suggested, it's a flame that protected and nurtured all those who occupied its 'home'. And right now, this 'Hestia' has designated the entire Sea of Life as her 'home', thus, any changes in it are deemed as 'normal', just like a normal home.
