This matter sounded a little convoluted, but once one carefully sorted through it, it was actually easy to understand.
The so-called Time Beacon could be understood as a sealed independent space. Time within that space stood still, forever remaining at the moment it had been sealed away.
The horizontal coordinate of this special space was somewhere in Antarctica, while its vertical coordinate was several days after Liusu and Yao Guang had driven away the outsiders from beyond the heavens. So long as one reached that point, one could obtain the Heavenly Evolution Radiance.
If people of later generations happened to see a fleeting flash of radiance in Antarctica, they were seeing the radiance of the past, unable to touch it. Thus, for tens of thousands of years, no one had been able to obtain the Heavenly Evolution Radiance. It had effectively been hidden away by those two best friends.
There were two ways to reach that point:
The first was to take the horizontal coordinate first. By standing in Antarctica and using some technique to directly communicate with the preset Time Beacon, one could come into contact with the radiance. This was the proper route; this had been why Liusu had originally wanted to go to Antarctica.
The second was to take the vertical coordinate first. The great battle against the outsiders from beyond the heavens several days ago had caused planar turbulence, making it a node through which one might possibly traverse. After returning to that time, one merely had to go to Antarctica and wait there for a few days. That was also quite close.
This was the alternative route, and it was somewhat dangerous. Since the great battle had caused the turbulence of space-time, returning there would inevitably mean facing the aftershocks of that battle. One might
