For ordinary players, most of them lack the ability to kill too many zombies, and the scattered zombie Essences in their hands leave them completely clueless on how to use them.
Because they haven't reached the level where they can utilize zombie Essences, they were overjoyed upon seeing Ryan's pricing.
[Great! I happen to have a few zombie Essences on hand.]
[An utterly useless Essence can actually be exchanged for a bottle of drinking water? Food and water are quite scarce in this dungeon.]
[I was just worried that this thing was useless, and now I can trade it for food. What a profit!]
Ryan quickly received a large number of zombie Essences. Although each player had only a small amount, the sheer number was impressive!
In a channel with over a thousand people, Ryan opened the trading page and found that a staggering three hundred players were trading, and the supplies he had put up were nearly snatched up.
