An extraordinary store system connects two time and space, two people, two hearts and a relationship. A peaceful citizen of the earth in the 21st century, a doomsday survivor of the earth in the 21st century, a trading system that travels through time and space connects the fate and marriage of the two.
"What the hell kind of trading system is this? It doesn't even have a price!?"
"Hey, both parties to the transaction have selected the items respectively. When both parties agree, the transaction will be successful and the items will be swapped. Okay, it's over."
There is no way to know the value of this unknown thing, knowing that this thing is worth a sky-high price. Different time and space, different item values, buyers and sellers can communicate to achieve the same purpose, take screenshots, text communication, voice communication, and, in that case, why not communicate face to face, right~
