Perfectly Round and Bright Moon

The farther Qin Mu walked, the more spirit weapons for everyday use he could see. There were also scholars near Surging River Academy that were testing flying carts which could carry passengers into the sky. The pill furnace was slightly smaller and didn't exhaust as many medicinal stones as flying ships, perfect for short distance flights.

He could still see some scholars forging Ice Dragon Fridge and selling the spirit weapons to the big families nearby. Ice Dragon Fridge was square like a big cauldron, but there was also a cover. Four bronze dragon sculptures were occupying the four corners. With medicinal stones, the green dragons would breathe out icy breaths.

During summertime, it would cool the air in the house and also store food by making it harder for food to rot.

There were mines beside the river, and numerous machines were mining while scholars were supervising and recording at the side.
