Four shichen before Li Xuan executed Yexian, a continuous drizzle fell over Beijing.
Inside the Wenhua Palace of the Forbidden City, Yu Hongshang was sealing documents delivered by the cabinet with a white-bright lamp.
At Yu Hongshang's lower left, the Sili Bureau eunuch Qian Long, standing to one side, was momentarily distracted by the nearby white-bright lamp.
The white-bright lamp was a recent invention, and according to The Court's patent law passed half a year ago, the patent was registered under the name of County Prince Fenyang, Li Xuan.
These lamps, powered by electricity, were ten times brighter than candlelight.
Therefore, when introduced in early June, they became explosively popular within Capital City.
The official residences and homes of nobles and the wealthy in Capital City almost universally adopted them; just by running an electric wire and installing a few dozen white-bright lamps, their estates were brightly illuminated.
