The auction last part

The quiet mood left Aruna and Maev a little apprehensive, they were feeling like they were in the middle of a forest with ferocious beasts and the trio were the prey.

"Does anyone give more?" Talbot saw that no one else spoke of an offer so he asked before starting the count.

"I offer six hundred and four crystals from the mine" Another person offered.

As Liu Yang had offered something worth around 574 crystals from the mine, he had to increase the value a bit according to the rules. So he offered six hundred and four crystals. Thirty crystals above the value offered by Liu Yang.

This bid was not to buy the device itself, but it is to see if Liu Yang will offer a higher bid or not. The nobles were curious as to whether he had more crystals or not.
