Eliminating Chief Gray

You're the one that helped me get rid of 白外星人卫兵 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 白外星人司令. 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 库尔兰草原 and 库尔兰草原.

Can you defeat these 白外星人司令 aliens and bring back 5 of their 笔记本 things? I think each 笔记本 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 笔记本! 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 笔记本 or two. Go find the high-ranking 白外星人司令, get their 笔记本, and come back. 笔记本 probably contains some juicy secrets!
