The second was an ordinary notebook, roughly two centimeters thick and ten centimeters long and wide, small and exquisite.

But this gray layer did not impair his vision. Dark places became slightly brighter, while the brightest light sources grew correspondingly dimmer.

He looked at Tangyuan and likewise saw no obvious traces.
The Clairvoyance Glasses could only reveal obvious traces, and these two things clearly could not produce traces of that kind.

In addition, while searching outside, Captain Luo had once used an item that bathed the entire city in golden light, making the traces left by abnormal things extremely obvious.
