  The precise control of Weyl physics in realistic materials oers a promising
avenue to construct accessible topological quantum systems, and thus draw
widespread attention in condensed-matter physics. Here, based on rst-principles
calculations, maximally localized Wannier functions based tight-binding model,
and Floquet theorem, we study the light-manipulated evolution of Weyl physics
in a carbon allotrope C6 crystallizing a face-centered orthogonal structure
(fco-C6), an ideal Weyl semimetal with two pairs of Weyl nodes, under the
irradiation of a linearly polarized light (LPL). We show that the positions of
Weyl nodes and Fermi arcs can be accurately controlled by changing light
intensity. Moreover, we employ a low-energy eective k p model to understand
light-controllable Weyl physics. The results indicate that the symmetry of
light-irradiated fco-C6 can be selectively preserved, which guarantees that the
light-manipulated Weyl nodes can only move in the highsymmetry plane in
momentum space. Our work not only demonstrates the ecacy of employing periodic
driving light elds as an ecient approach to manipulate Weyl physics, but also
paves a reliable pathway for designing accessible topological states under
light irradiation.
