This ear-splitting sound, like the tolling of a bell, isn't actually a real bell. If you listen closely, you'll notice a crisp mechanical undertone at the end—it's not a bell, but the unique melody of clock hands turning.
When the three clock hand noises rang out, the plaza erupted in applause and cheers. The adults shouted, "A new day begins!" and children hopped around clamoring for breakfast. The same daily clock sounds may seem meaningless, but everyone in the plaza is joyful for this moment.
Xu Huo followed the crowd, stopping behind several people standing at the edge of the plaza, calibrating their clocks to the Time Tower.
Calibrating the time isn't done by hand; first you use a calibration device to select the clock on the Time Tower, then the device starts working, adjusting the new clock according to the tower's time till it's perfectly precise.
