There is a large hole underground in the square, with a diameter of about five meters, surrounded by the wreckage of architectural debris, empty water guns, and overturned damaged vehicles.
Besides small water guns, there are also large water guns here, but still no traces of bodies.
A music box made of shells is placed at the edge of the hole, and to transmit sound so far to the outskirts of the city, I thought the music box must be quite large.
It turns out it's about the size of a tablet, with every component exposed outside, and the material of the parts is unusual—some kind of glowing liquid.
The liquid acts as components in operation, producing the sound of the music box. They are in the shell, seemingly bound and drawn by some force, cycling continuously, spinning without rest, gathered but not scattered.
Why it can keep spinning, I really can't see, and don't have the time to think carefully, because Bi Shi had already picked it up.
