This is a small game developed independently in C++/OpenGL, and the current development work has not yet been completed. The game features a 2D God perspective, similar to a game developed by RPG Maker, where players can explore a vast world that is carefully constructed.

In the depths of a fog-covered forest, 19-year-old Lin Xiaoyu goes back and forth between school and home day after day. This girl, who lives alone on the edge of the forest, lost her mother when she was eight, and her father, "working overseas," only keeps in touch with her through cold emails. Until one day, her friend Xiaoxia discovers a mysterious iron door in the forest, and their peaceful life starts to crack.

At the same time, the multinational biotech giant Tanxl is carrying out a secret plan in the town. This company, known for its medical research, has set up an underground lab deep in the forest. As time goes by, the town begins to experience all sorts of strange occurrences: withered trees, missing residents, bizarre weather... and all of this seems to be related to Tanxl.

When Lin Xiaoyu decides to uncover the truth, she finds that her fate has long been intertwined with this mysterious organization. In this isolated town, a life-and-death adventure is about to unfold...
