It had been a couple days since the successful operation on Megara's face but Veena kept her under watch in the infirmary as she healed her face slowly, Ryuu had watched the entire process from draining of poison to applying of antidote to making it harmless then removing parts of the face, before regrowing the right side of the flesh the eye and most importantly the brain.
If it were my previous world people would have laughed at the thought of regrowing a brain yet it was possible in this world and it certainly helped as his curiosity was being satiated by Maheswara, and a couple of days later Megara awoke from her medicine induced coma.
