"Feather of Ruin Unleashed!!"
Mei raised the Tianhuo Greatsword in her hand and swung it forward with all her strength.
The power of the strongest Key of "Destruction" was completely unleashed.
Tianhuo, capable of destroying everything, swept through the entire surrounding Higanbana Sea.
Before the terrifying Tianhuo, none of the Higanbana could last even 0.0001 seconds. They vanished instantly.
"No..."
The twelve kimono girls only managed to utter one word before Tianhuo swallowed them, leaving not even ashes behind.
Tianhuo rapidly spread outward. In the blink of an eye... it had expanded hundreds of kilometers.
At that moment, Mei's body was also completely reduced to nothing by Feather of Ruin Unleashed. In the instant of death... she regretted it somewhat. She should have switched to Kallen's or Fu Hua's body before using Feather of Ruin Unleashed, even if it would have cost her one chance to switch.
But... dying did not feel good, even though Mei had long prepared herself for it.
The terrifying Tianhuo continued spreading outward until it had completely destroyed every Higanbana Sea. It even advanced several hundred more kilometers, turning an area roughly equivalent to central Japan completely into nothingness.
Only the Sanzu River, the foundation of the underworld, barely managed to block the terrifying flames. Of course, that was also because only the outermost flames had reached it, weakened by an unknown extent.
Fortunately, the underworld was vast and sparsely populated. Furthermore, this area was almost entirely Higanbana territory, so not many souls died in Tianhuo.
If something like this had been unleashed in the Human World, Japan would have basically ceased to exist...
The entire Higanbana Sea had completely disappeared, leaving nothing behind. Even the roots and seeds underground had died beneath Tianhuo's intense heat.
There was nothing left in this area
