Please Leave My Island Before Midnight

All the people were thrown into the endless sea, and each person only had an island, a core, and a fog bridge that appeared randomly every day. When midnight arrives, the bridge is broken and no one is left; killing people cannot take over the island, only destroying the core will make the island owner lose everything. Ouyang Chen wakes up on the abandoned lighthouse island. He can identify hidden traces from the objects he touches with his own hands, but he can never see through people's hearts. A glass of water can exchange lives, or buy betrayal; a rescue may lead to an alliance, or it may bring the murderer to the door. There are no laws, no judges, and the promise is only worth the price you are willing to pay. What he wants to protect is not just an island, but the freedom to still say "no" every time. Please leave my island before midnight.
