  We explore the dynamic shear viscosity of the undoped ABC-stacked multilayer
graphene based on the chiral-$N$ effective Hamiltonian, where the chirality $N$
is equivalent to the layer number. We investigate the dependence of the dynamic
shear viscosity on the frequency in the collisionless regime and calculate
Coulomb interaction corrections by three leading order Feynman diagrams:
self-energy diagram, vertex diagram, and honey diagram. We propose that the
dynamic shear viscosity is generated by the relaxation of momentum flux
polarization through electron-hole excitations, and that the interaction can
amplify this effect. Furthermore, our research indicates that the dynamic shear
viscosity exhibits a robust linear positive dependence on $N$. This finding
suggests that by making modifications to the number of layers in graphene, it
is possible to finely tune the electron viscous effects.
