The materials required for the police bell weren't extensive, but they did include copper.

[Hundredfold Amplification Triggered, Obtained Police Bell x101]
In an instant, 101 police bells appeared before Fang Hao's eyes.
The bell bodies were not large, with a base diameter of approximately 40 centimeters and a height of 50 centimeters.
They were entirely iron-green, with complex patterns carved on their surfaces.
Inside each bell body, a hanging clapper was suspended. A gentle swing was enough to strike the bell.
Summoning a few patrolling skeletons, Fang Hao instructed, "Place these four on the arrow towers separately."
The police bells could be mounted on the arrow towers to sound an alert when danger was detected.
