"Damn it, I can't observe anything." Gu Shanhai cursed.
He originally thought to fleece the big nothing a bit, but after observing back and forth, he found that he couldn't effectively observe any other data. It was as if this observation method was specifically designed to track its movement and time.
As for where the observation method came from, it was given by the world when the gods fell and turned into Saints, akin to a gift from heaven. Thus, Gu Shanhai found it quite difficult to modify because its scope was limited from the moment of its creation; even if he tried to change it, he could only play in a snail shell, never achieving the effects he wanted.
After struggling for three days, Gu Shanhai gave up and could only wait to see more when the big nothing came closer.
