Comments of chapter undefined of Birth of the Demonic Sword

I really enjoy this web novel, but I feel I need to mention something that took me out of the immersion in this chapter and some others previously: the description of geology. The way the ground and/or continents are described in the story is like they float on top of the ocean. In the story, when part of a continent is destroyed, it sinks into the ocean. But that's the exact opposite of reality. In reality, the oceans (and all other bodies of water) accumulate on top of solid ground. If you destroy the ground somewhere, it doesn't sink into the ocean – you just unearth more ground underneath, all the way to the core. I thought the author knew this because of the journey to the core, but the descriptions in this chapter of all continents being destroyed leaving only a few islands floating around shows that's not the case. You could make an argument for the new continent since it fell out the sky into the ocean, but you can't for the old continent. Soil doesn't float. You can throw as much soil, rocks, mountains as you like into the ocean, it will sink. EveOfChaos, I hope you will see this and take into consideration. And while I'm at it, another thing that doesn't fit is the time it takes them to fly around. Assuming they fly about as fast as our airplanes, if it takes them weeks or months to travel from place to place, it would mean their world is as large as our Sun! But at least this could potentially be explained by invoking "Breath" and handwaving. But part with the sinking continents cannot. Aside from that, been loving the story and looking forward to what comes next!
