"About the meat…" and when they felt they'd gain little in the end, William slowly added, "you can have it. Distribute the meat after salting it properly. Store these in your rings, as we'll depend on this meat for a long time."
William knew that eating monster meat wasn't just used as a tasty and rich food in energy, it could even support one's physique and enhance one's spirit power to a limit.
The knowledge about eating monster meat was quite limited in this world compared to the outside one. Eating monster's meat of higher grade wouldn't just enhance one's physique and power, but also would help in cleansing all the impurities in one's meridians and main nodes, ending up accelerating the speed of one's training and increase in spirit power as a result.
William didn't expose any of that, and simply let them accept such trivial gain in their eyes.
As for when they'd realise how precious and extremely rare this chance was, William didn't care or even think about that.
