  We investigate weak cosmic censorship conjecture in charged torus-like black
hole by the complex scalar field scattering. Using the relation between the
conserved quantities of a black hole and the scalar field, we can calculate the
change of the energy and charge within the infinitesimal time. The change of
the enthalpy is connected to the change of energy, then we use those results to
test whether the first law, the second law as well as the weak cosmic
censorship conjecture are valid. In the normal phase space, the first law of
thermodynamics and the weak cosmic censorship conjecture are valid, and the
second law of thermodynamics is not violated. For the specific black hole under
scalar field scattering we consider, in the extend phase space, the first law
of thermodynamics and the weak cosmic censorship conjecture are valid. However,
the second law of thermodynamics is violated when the black hole's initial
charge reaches a certain value.
