Peter didn't say anything else to Sean Knight, but just waved his hand and let him leave, staying behind to learn more details about how Sean had found the box.
"…He went to a bay and said that it should be a place where small boats could stop. He guessed that if large boats couldn't stop, they might send small boats to unload things and start digging for traces nearby. Then, he dug up this box under a tree."
"How deep did he dig?"
"About a meter deep."
"Only this box, and nothing else?"
"Yes. When the box was opened, I was watching. There was nothing inside but seawater."
"Well, keep a close eye on him tomorrow, I think this guy is trying to play tricks…"
…
The next day, Sean still got up early. After eating breakfast, he continued to "patrol the island" with his backpack.
Charlie followed him silently.
To Sean's surprise, Peter and the others came not long after them.
