PinCell use new_unchecked

Please note that there is a problem with this code. If Drop contains 'scope, try to call drop it will fail.
Consider erasing the 'scope of the Scope and using the 'scope of WScope package instead to ensure the correctness of the correct API.

This is also the direct reason why I designed to use WScope to wrap Scope, but I forgot it for a while. :rofl:
