The Plague Reaper became Adam's strongest opponent after Essence Thunder Demon. This was not surprising since one of them was a Top-1 and the other a Top-2 among all Purple Threat monsters.
Oddly enough, it was the meat of these two monsters that Adam had tasted. Each time it was not by choice but by coincidence.
At the Red Feast where Magnus had invited him, the main course was the meat of the Essence Thunder Demon, the one he had killed.
Now he had the heart of the Plague Reaper in front of him, and the credit for that went entirely to Osana, for she organized the whole thing.
It was worth realizing that the rarity of their meat on the market of the Red Feast was drastically different. It wasn't just the gap in their strength and frequency of appearance, the Plague Reapers were much fewer than the Thunder Demons and they showed themselves much less often.
Their size was also important.
