In 20XX AD, a "Blue Light Event" suddenly broke out around the world - a soft blue light flashed across the entire earth, and all humans instantly lost consciousness. When they woke up again, everyone found themselves on a small island floating on the endless ocean, with an "island survival system" similar to a smart watch in their hands.
The system prompt shows: Human beings have been transported to the "Endless Sea", which is a mysterious world composed of countless islands. The seawater contains special energy, and the islands will slowly "grow" over time (expanding area and increasing resources). The core of survival is "exploration, construction, cooperation", and the ultimate goal is to find the "center island of the endless sea" and unlock the passage back to the earth (or choose to stay in the sea and become an "island lord").
