We conduct an indirect dark matter (DM) search in the Galactic Center, focusing on a square region within 9^ in Galactic longitude and latutide, using 2, 865 days of data (8 years) from the High-Altitude Water Cherenkov (HAWC) Observatory. We explore DM particles within the Weakly Interacting Massive Particles framework with masses from 1 TeV to 10 PeV. Analyzing three annihilation channels (bb, τ^+τ^-, W^+W^-) and three density profiles (Navarro-Frenk-White, Einasto, Burkert), we find no significant excess and set 95\% confidence-level upper limits on the velocity-weighted annihilation cross section. Our results provide the first constraints on DM particles well above 100 TeV using gamma-ray data from the Galactic Center, with the strongest limits O (10^-24) ~cm^3/s, from the τ^+τ^- channel and the Einasto profile.
