  "abstract": "Lieb-Robinson bounds formulate emergent causality in quantum many-body dynamics. In this Letter, we study interacting bosonic systems with long-range interactions, in which both the standard assumptions of short-range interactions and uniformly bounded local energy scales are absent. We derive upper and lower bounds whose effective light-cone exponents are governed by a nontrivial interplay between the decay exponent $α$ and the bosonic interaction order $p$. The propagation protocol concentrates bosons within blocks, creating a mediating sublattice with amplified interactions. For $p\\ge4$ and $2d<α\\le2d+1$, the resulting exponents coincide, determining the optimal leading light-cone power. The upper bound includes $α=2d+1$ with arbitrarily small exponent loss, using a fixed-$k$ extension of the bounded-interaction result. Our results reveal that the interplay between long-range couplings and unbounded bosonic degrees of freedom gives rise to a richer light-cone structure than in either long-range bounded systems or short-range bosonic systems alone.",
