What is the detailed story of Man-eating Island?

One day, a beautiful island appeared in the deepest part of the East China Sea in China. Gradually, curious people began to land on the island. Half a month ago, Katie's good sisters decided to explore with the "donkey friends". A week ago, a seemingly ordinary but bizarre WeChat invited Katie, Qingyun, Loki, Mia and Bozai to get together and take them down to the scenic East Island under the guidance of the boatman. These five people and their party seem to be going smoothly, but they don't know that danger has quietly arrived. Empty islands, the sun rising in the west and setting in the east, the dense green vines crawling, the "caves" dripping with mucus and piled with white bones, the Bitan Lake, which is full of fairy dust but can erode bones, and Bo Zi's bizarre death all make people feel incredible. The sudden appearance of the "Mystery Man" and his suggestion pushed them completely to the near-crazy fear, but they have fallen into an island of death that they cannot extricate themselves from.
