We hereby present both our experimental and theoretical findings from a comprehensive investigation into the topological surface state of Bi-doped PbSb₂Te₄. Our study demonstrates a compelling observation: a pronounced hybridization with the bulk states has significantly modified the morphology of the distorted Dirac cone.
