The Gate of Time and Space Starts from the Handover Country

Geological prospector Lin Yi discovered a "door" connecting to another world deep in the rock formations. Behind the door is the planet Gaia - an apocalyptic world where civilization collapsed due to the forbidden experiment of "Source Crystal". When Lin Yi chose to report to the country, he never expected that he would become the only "key" to the two worlds. What's more, I didn't expect that behind the so-called "source crystal pollution", there is a terrifying truth that spans dimensions. Doors are no accident. Our world has long been marked as the next sacrifice of the abyss.
