At this time, at Locke's home, he took out his smartphone and planned to call Roy Auction House in the Blue Kingdom to ask if there was an auction of the divine spar.
The owner of a level three castle could also add a summoning system. Before Locke became the master of a level four castle, he wanted to add a summoning system first.
"Hello, Roy Auction House. What can I do for you?"
A gentle voice came through the phone.
"I want to buy divine spar. I wonder if you have such resources now."
Locke said.
The divine spar was very rare, but for ordinary castle owners, if they obtained such a treasure, they would rather exchange it for crystals.
Because for the owners of ordinary castles, even if they could cultivate one more system of castle creatures, they did not have enough crystals to cultivate more castle creatures.
