The Dragon Emperor had extraordinary reflexes and a nervous system that was biologically engineered to make his conscious perception of time exist in a different dimension by itself. And yet, expectations worked against him in this particular moment. He had expected Amare to be completely done.
More importantly, he couldn't have fathomed that Amare would be able to use nature manipulation, something that was exclusive to elves.
This delayed his reactions, causing him to fail to react in time to Amare's swift attack. Leaves, branches, and even wood emerged from her open wound, entering his mouth and piercing him from the inside out.
The inner lining of his mouth was not covered in invintium scales, allowing her to pierce his flesh much more easily than would have been possible on the exterior of his body. Blood splattered from several wounds within his mouth as the wood dug into his flesh, inflicting many wounds from the Dragon Emperor.
