Lu Ping'an's temporary residence was surrounded by various varieties of Lamplight Grass.
They lit up the area as bright as day, creating a rare source of light in the long night.
Many wealthy families and aristocrats also had firewood and oil lamps burning constantly, but those who lit their homes as brightly as Lu Ping'an did were a rare few.
After all, with the passage of time through the long night, any object with the ability to illuminate became increasingly expensive. As lamp oil reserves dwindled, lighting up one's home became more a symbol of status rather than a practical necessity.
Nowadays, lamp oil for lighting has become a military supply restricted by the territories, and even the fastidious nobles and rich merchants have gone crazy for firewood, which they once sneered at.
