Eliminating Chief Gray

You're the one that helped me get rid of 葛雷族人 the other day at the Kulan Field, right? The research on the force controlling them is just about to be concluded, and it's taken longer than expected, but I'm glad you're here now. I have something else to ask you for a favor. Will that be alright? Would you like to at least take a listen?

Thank you for all your help. Did you know that there are ranks even amongst the Grays? We've found out about high-ranking Grays that have jurisdiction over the other Grays in this area. Each is called a 葛雷元老. There's not that many of them amongst the Grays, so it was really difficult to track them down. Anyway, they should probably be in 克嵐草原Ⅳ and 克嵐草原Ⅴ.

Can you defeat these 葛雷元老 aliens and bring back 5 of their 記事本 things? I think each 記事本 contains some very valuable information. Come back to me when you have them!

Really...? I understand. Everyone seems to get a tad hesitant when dealing with ugly aliens like them. If you ever change your mind, however, I'll be right here.

Ah, you got the 記事本! It took me a while just to find those guys... I guess I need to work harder! Anyway, here's your reward for helping out! I know this isn't much, but please take it!

Thank you so much. Now, let's try to decipher this note. Just as I thought, this is written in alien language, so it's near impossible to understand what's written here, but with a little time, I'm confident that we can decipher this book. I gotta get this going, so I'll see you around!

It seems like you're still missing a 記事本 or two. Go find the high-ranking 葛雷元老, get their 記事本, and come back. 記事本 probably contains some juicy secrets!
