When Lin Yuan used True Data to check this source-type item that was like an amber button-shaped crystal, he immediately decided that he was going to win the auction for this no matter what. This was a source-type item that he had been yearning for.
If he nurtured it properly, not only could it protect himself, but it could also play a controlling and attacking role. However, its contract conditions were a little too harsh, so harsh that it would make everyone flinch.
A Creation Master would appraise auctioned source-type items on the spot so that the Creation Master could judge what contract conditions it required.
