We develop a resurgence analysis for large central charge (large C) expansions in two-dimensional CFTs using the Coulomb gas formalism. Through the exact Borel-Laplace representations of the conformal blocks I1(C, z) and I2(C, z) associated with the four-point correlation function \(\langle {\phi }_{2,1}\left(0\right){\phi }_{2,1}\left(z, \overline{z }\right){\phi }_{2,1}\left(1\right){\phi }_{2,1}(\infty )\rangle \) , we demonstrate that I1(C, z) participates in the Stokes phenomenon of I2(C, z) (and vice versa), and establish that monodromy in z arises from alien calculus in the Borel plane variable ζ (Borel dual to C). From a given conformal block, resurgence theory thus enables us to discover other internal operators (conformal blocks). This approach establishes a non-perturbative connection between conformal blocks, shedding light on the resurgence phenomena in more general quantum field theories.
