Lamute's Secret Code

Benns Ruberen's Mind-boggling Letter Greetings, I am Benns Ruberen, the proud leader of the Lamute Gang. I'm the one who sent you our gang's journal and notes. Have you gotten to know our crew? To achieve great things together, we must understand each other well. If you're still feeling awkward around our members, there's no need to read further. Conquering the world's most mind-boggling island alone is impossible. Aren't you curious about that island? It's said to hold a treasure worth a fortune. However, there's a problem. Our members who infiltrated the island haven't returned. I need your help to find our missing members! But our crew isn't fond of working with strangers... If you pass our gang's final entrance test, we'll share a secret known only to us. Discover Lamute's secret code from Carter, Euron, and Chasey!
