Amelia stared blankly before asking, "If I'm not wrong, it hadn't recorded your mana signature, right?"
This lock has only been invented around 8 months ago.
And at that time, it had already caused quite a stir because people felt that they would have additional security in many things.
After all, everyone's mana signature is different.
Just like fingerprint.
No one has the same fingerprint in the entire world.
The mana signature was the same and they already have device to record the mana signature through inputting mana. Though, the amount of mana needed to input was still not efficient enough and the researchers were still working on it.
But it was good enough for them.
After all, they would not really record more people's mana signature into this system.
And when this device was made, Riya was clearly still in the other world. Samuel had only recorded his mana signature these days after his return since he wanted to modify the training grounds.
But how about Riya?
