"Chirp chirp!"
Released from their commands, Rock Sparrow and the two crows pecked frantically at the feed on the windowsill. Inside, Jing Yang and Shizuku were both releasing dense aura throughout their bodies to maintain Ken, cultivating without moving.
The clock used for timing sat on a nearby table as time trickled away with each changing digit...
