Swan Lake?
Looking at the simple line drawing of a map on the clue, and the only place name marked Swan Lake, Sean Knight felt somewhat regretful.
Is this it?
Is this what to use to find the treasure?
"Take a look at the backside," Brown smiled when he saw Sean's expression, "The back is a route that my ancestors took before, and the marked points are the places they visited. I believe it will make it easier for you to find."
Sean felt that this seemed more reliable.
"I'll provide you with a satellite phone. I'll be at the base waiting for you and possibly join a random team to search. Keep in touch with me if there are any updates."
Brown gestured, and a beautiful maid brought over a box. Sean opened it and found a satellite phone inside.
After taking the box, Sean tested it. The signal was full - of course, this was in the city, he didn't know how it would be in the wilderness.
"I've prepared three spare batteries for you. I believe that should be enough."
