It turned out to be a bunch of fireflies!
Perhaps because there were lights on in the house, the fireflies weren't very bright. Xiu Xi noticed this, glanced at Ruan Jiaojiao, and turned around to turn off the lights.
"What's going on, why did the lights go out, is there no electricity..." Just as a member of the Ruanlin Family approached the doorway, she saw the lights go out and thought there was a power outage, muttering suspiciously for a moment. When she caught sight of what was happening inside the room, she fell silent.
Kneeling in the mosquito net, Ruan Jiaojiao looked up at Xiu Xi, who was standing outside the net with a glowing bottle in his hands. The bottle was quite big, a clean, shiny glass bottle, with a piece of red gauze tied around the top. As the bottle glowed, the red cloth atop it shimmered as well, incredibly beautiful.
