   Deconfined quantum criticality (DQC), driven by deconfinement and condensation of fractionalized particles, shows fascinating equilibrium critical behaviors beyond the prevalent Landau-Ginzburg-Wilson (LGW) paradigm. Here, for the first time, we study the dynamics of DQC under an external driving. Remarkably, we find that the deconfinement dynamics can invalidate the celebrated conventional Kibble-Zurek scaling, which has bear vast examinations in the driven dynamics of LGW phase transitions. An unconventional Kibble Zurek scaling (UKZS), which takes the driven effects on the deconfinement dynamics into account, is then constructed. Exotic dynamic scaling behaviors are discovered obeying the UKZS. Our work not only provides new insights into DQC and Kibble-Zurek scaling but also raises a prelude to the studies of nonequilibrium properties of the exotic critical phenomena beyond LGW paradigm.
