Silas was silent for a while and frowned.
Even though this stack of scrolls are common, would the people sent by the Fourth Head of the Wansu City not try to check it?
Negligent?
Silas was not sure but there was also another possibility.
That another person put it here after the people sent by the Fourth Head of the Wansu City came here.
'There are only four mana signatures in this living room. Three are from the people sent by the Fourth Head while the other one is Aya.'
Silas had developed his dark magic to the way that he could detect the mana signature from different people. Mana signature was the hardest to change.
A person's appearance could be disguised and they could use some method to cover up their real appearance.
But a mana signature was developed along with their growth. It would not change easily.
'I'll check later.'
