Koop's Deal

After I used those Red Tomes to negotiate with the MoonElf Ambassadors, we concluded they would pay me well for those Books. They will pay me one hundred million 金币. Isn't that quite a price?
Those Books? Ah. After some research, I discovered Dallain dug up the Books in Silancium. When I heard this story, the guy who was telling it paled and said those Books are 'ancient documents for those who desire great power,' but how can documents give any power, am I right?
Anyway, I'm to negotiate. I heard the MoonElves put 'Beast 宝石' on the foreheads of the monsters around the area. This let's them control the monsters. I think they're plotting against me. So while I lead my men out, I have another order to give you that will cause them some trouble.

We are going to meet the MoonElves in the <HFFFA7272>Northwest of Baran Dyke Fortress Three<HFFFFFFFF>. Go there and kill <HFFFA7272>Dark Wyverns<HFFFFFFFF> until you get <HFFFA7272>10 Beast 宝石<HFFFFFFFF>! Got it?

Hurry up so we can make the appointment. Kill <HFFFA7272>Dark Wyverns<HFFFFFFFF> in the <HFFFA7272>Northwest of Baran Dyke Fortress Three<HFFFFFFFF> until you get <HFFFA7272>10 Beast 宝石<HFFFFFFFF>.

I dealt a really good blow to them. One tried to summon a monster as I expected, but it failed since you took the jewel out of the monster's forehead. They had to accept all my terms. Of course they'll get the book they wanted. If you have a very powerful weapon, you may get hurt yourself if you keep wielding it too often. That's common knowledge. Anyhow, you've done well.
