With this kind of sight, creating a Supreme Law is something they can do with their eyes closed. With their eyes open, they can track their data clip all the way to Monarch High Heaven.
The only caveat is that their sight is not hidden. Many powerful entities can sense their gazes on them. Even Supreme Origin gods can sense their gaze.
So they didn't focus on the courier transporting their data clip. They only focused on the data clip itself so as not to alert the Supreme Origin god. Eventually they saw Monarch High Heaven pick up the data clip and go to his base.
They couldn't see into his base because it was protected by a Supreme law. They could try to break in, but that would surely alert the owner of the Supreme law if they haven't already been alerted to their prying eyes.
