The 密码

Remember the time you were running around for the Gnomes? I don't know what had happened then because I only stayed here but a letter arrived for you this morning from a Gnome chief. Here, take a look.
Oh you don't know how to read the Gnome language? Hmm. Then I'll read it out for you.

We needed the horns of the monster Borun to read the records. It was because our ancestors had engraved the passwords on its two horns. But the warriors we sent to acquire them were annihilated and only one had barely managed to return alive. He said that they did cut off one of Borun's horns after much difficulty, but it fell down to the rocks and they couldn't retrieve it. So we are requesting for your help. Please hunt <HFFFA7272>Borun<HFFFFFFFF> in <HFFFA7272>Hawk's Plateau<HFFFFFFFF>, and cut off and bring the <HFFFA7272>Left Horn of Borun<HFFFFFFFF> to us. You also need to find the <HFFFA7272>Right Horn of Borun<HFFFFFFFF> in the <HFFFA7272>Rocks<HFFFFFFFF> on the way back.

There are several other requests too but please take care of this first. The Elder has charged me with the responsibility of overseeing this matter. So please come to me when you have obtained the horns.

I don't think you need to think too much about it. Let's just do as the letter instructs. You just need to hunt <HFFFA7272>Borun<HFFFFFFFF> in <HFFFA7272>Hawk's Plateau<HFFFFFFFF> and cut off the <HFFFA7272>Left Horn of Borun<HFFFFFFFF>, and then find the <HFFFA7272>Right Horn of Borun<HFFFFFFFF> in the <HFFFA7272>Rocks<HFFFFFFFF> nearby, right?

Thank you. So these are the horns of Borun.
They look quite heavy, so why don't you give them to me? I will then tell you what needs to be done next.?
