I debugged the code, found the value of "db_service[key]" is "region!child@1", and it was created by the method add_cell_to_compute_node which is from "nova/cells/utils.py" .
I also tried "nova hypervisor-list", and got the following result:

    +----------------------+--------------------------------+
    | ID | Hypervisor hostname |
    +----------------------+--------------------------------+
    | region!child@1 | devstack |
    +----------------------+--------------------------------+

The ID is also not an integer, which is different with not installed n-cell one.
