According to Emperor of Shang, the location of Destiny Platform was called Dimensional Airspace. The so-called airspace was an area void of everything.
In that area, there was nothing other than the Destiny Platform. Furthermore, it was virtually infinite. To find the Destiny Platform in the dimensional space depended on whether one was destined to find it.
Currently, most of the creatures that had ascended the Destiny Platform's staircase had likely gone through the Cube. They had never been to the Dimensional Airspace.
It looked like the Cube had reduced the difficulty of ascending it, but in fact, it had increased the mortality rate.
In the past, people couldn't find the location of the Destiny Platform by going through the Dimensional Airspace. They knew that it wasn't their fate. Giving up on ascending the Destiny Platform gave them a chance to escape from the Dimensional Airspace.
