  In this work, we define a quantum gravity state on a nice slice. The nice
slices provide a foliation of spacetime and avoid regions of strong curvature.
We explore the topology and the geometry of the manifold obtained from a nice
slice after evolving it in complex time. We compute its associated
semiclassical thermodynamics entropy for a 4d Schwarzschild black hole. Despite
the state one can define on a nice slice is not a global pure state,
remarkably, we get a similar result to Hawking's calculation. In the end, we
discuss the entanglement entropy of two segments on a nice slice and comment on
the relation of this work with the replica wormhole calculation.
