Inside the simulation room, an entirely new environment had been generated. It was a mountain around four kilometres tall, almost half the height of Earth's tallest mountain, Mount Everest. This mountain was actually the site of a unique racing circuit. The racing circuit was built on and within a mountain; in other words, its tracks didn't just cover the mountain but continued within the mountain.
The name of this racing circuit was the Infinite Eight Circuit, and it was the location of the next race of the Nadire Underground League. Of course, this was just a simulated version of the actual venue generated by the Simulation room, but it was still as good as the real one.
Racing circuits were classified into four levels based on their difficulty, and the Infinite Eight Circuit was on the second level. Apart from being one of the longest tracks in all of unofficial drift racing leagues, it had a complex terrain that was filled with varying degrees of risks.
