Metropolis: I Have a Trading System

If you like relaxed and refreshing articles and urban systems, you can come and have a look. Transactions do not have to be reciprocal. Sometimes a piece of ordinary bread can sell for a sky-high price. When the trading system comes, the originally ordinary items are no longer ordinary. The past, future, another world, and parallel time and space can be traded as long as necessary. Gold, silver, jewelry, black technology, you will never imagine what you can get from trading! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
