In the void, a massive door flickered in and out of sight.
Just like the chains from before.
Amid the flickering, Qin Ran made out the door's appearance.
It was entirely black, with the texture of stone and an extremely rough surface. Apart from being rectangular and vaguely resembling a door, it had almost nothing that could be associated with one.
There was no frame, no handle, and no decoration whatsoever.
However, it had guards.
Before the flickering door, an intense sense of danger kept surfacing.
Even though there was nothing within Qin Ran's field of vision.

There were still subtle differences.
It was not entirely about their presence.
There was also where they stood.
The former could be concealed to a certain extent through training, but the latter would not change.

When he moved away from that flickering chain, the sense of danger
