Just from the perspective of the Shadow Tower, recording every scene he sees, including details like breath and sound, then transmitting them to the image stone in his hand—in simple terms, it's livelier surveillance.
And he would use these images as clues to find traces of the "Qing Ge Master" and use it as evidence.
However, the assassination plan encountered some unexpected issues later, as Ying Mingyue rescued Qing Ge, not that mysterious "Qing Ge Master".
So he could only accept the bad luck without thinking much.
He casually scanned these shadows at the time and didn't find anything unusual, so he dropped the matter.
But now he unearthed these shadows again, unwillingly examining them meticulously:
The Shadow Tower appeared in the Sen Luo Tower.
That's when he intercepted the shadows.
The images kept moving.
Because the Shadow Tower was observing the surrounding environment and people.
This is a habit only a Dead Soldier skilled in assassination possesses.
