Sam took out a large metal sphere and placed it on the table.
It looked to be the size of a football.
The employee took a look at it and then turned to Sam.
"I found this in one of the underwater sea graveyards. From the runes I found, it is stated that this is a mechanical puzzle lock and inside it has a special blood essence of a mystical sea creature. I have tried my best to unlock it, but I was unable to find the right pattern.
I would like to avail your services to unlock this."
"Are you willing to give out the details of the ruins?"
"Actually, I don't know much about it. But I found some of the stone plaques there and here they are."
Sam took out a bunch of stone plaques and gave them to the attendant.
The person looked through them and noted down every detail.
