There was a mysterious place that was shrouded in fog all year round. Not only was it inaccessible, but even the most advanced satellites in the sky could not penetrate it and explore. They could only vaguely make out the outline, but they had no idea what was inside.
There had been dozens of scientific research teams that had gone deep into the hinterlands of Shennongjia, using all kinds of cutting-edge equipment and even sacrificing several precious lives.

In other words, this was one of the few unknown lands in the world.
