He is just a rich brat!
Holding the magical rusty key in hand, the old wizard moved to the edge of the auction stage to explain.
"Some of you might not know about the importance of this abyssal key. But this key is a token for obtaining one good treasure. Even though we don't know which demi-god inheritance ground awakening this time, one thing is sure.
On every inheritance ground, there will be a treasure trove palace where several rare treasures appear. To obtain these treasures, one must spend hours removing the bind on each treasure. But with this Abyssal key, you just need a second to get your desired treasure.
This key has a single use. But it's definitely worth it, to unlock your desired item in the treasure trove palace. Who knows, you might find a powerful weapon that can turn the planet upside down."
After giving a long explanation, the old wizard placed the key back on the try and let Jia handle the auction.
