Zach looked into the portal, but he couldn't see anything past the borders of the portal. It was the same when he had summoned the magic shop.
Zach didn't necessarily want to go to the magic shop, but he wanted to meet Xie Lua and ask her about the progress of the bidding of his MP potions.
He simply wanted to check if two people could enter the same portal for a magic shop.
Zach held Aurora's hand and said, "You go first. If only one player can enter, I don't want to ruin your shopping."
Aurora entered the Magic shop without any problem, and then Zach too.
"...!"
They both were surprised, but that wasn't the case.
Only one player was allowed to exist one at a time in the magic shop dimension. However, Zach was now Xie Lua's business partner— a trader, and that gave him the ability to enter and leave the magic shop dimension whenever he wanted to.
Of course, summoning the magic shop was necessary to enter it.
