Mafu Lake is a peculiar lake formed after a meteor phenomenon, and there have been quite a few records of aliens in this area.
In the early 20th century, someone discovered a cave in this area with an unknown destination. After decades of exploration, no one has truly reached the bottom of the Mafu Lake cave, so there are rumors that this cave leads to hell, and it's the only road to hell on Earth.
Considering that the lizards living in this area can enter the underground, someone once attempted to install camera equipment on the lizards to explore underground, but once entering deeper underground, any advanced equipment would malfunction and fail.
After numerous experiments, the US Government finally ordered the "road to hell" to be covered with a soil mound, until the current international exchange activity, proposed by Lady Serlin, to conduct the final team assessment in this area, bringing it back into the public eye.
