Four top scientists checked into the research cabin of the mysterious island and were ordered to investigate strange places around the world. The time and space wounds in the Bermuda Triangle, the living labyrinth underground in the Maya, the language-devouring rainforest, the Shennongjia folding space... Every time they unravel a mystery, they get closer to the truth that subverts their cognition: these strange places are not isolated phenomena, but the scars left by a grand "experiment" that spans thousands of years.
And they gradually discovered that the data they collected on each expedition were passively executing an unknown "final agreement." The research cabin is not a shelter, but a petri dish; they are not observers, but the most critical samples. When the tenth door opens, they will have to face the ultimate choice: to complete the agreement and welcome an unimaginable "new world"; or to betray the mission and save the last fire for mankind in the apocalypse.
The archives of the global mystery are being written automatically, and the last page will be decided by their own hands - whether it is the truth or destruction.
