Observed protostellar outflows exhibit a variety of asymmetrical features, including remarkable unipolar and bending outflows. Revealing the formation early evolution such outflows, especially is essential for better understanding star planet because they can dramatically change mass accretion angular momentum transport to protostars protoplanetary disks. Here, we perform three-dimensional non-ideal magnetohydrodynamics simulations investigate in magnetized turbulent isolated molecular cloud cores. We find, first time our knowledge, that outflow forms even single low-mass system. The results show driven weakly cores with dimensionless mass-to-flux ratios $\mu=8$ $16$. Furthermore, find $\textit{protostellar rocket effect}$ outflow, which similar launch propulsion rocket. ejects system from central dense region outer parent core, ram pressure caused by its ejection suppresses driving additional new In contrast, bipolar moderately core $\mu=4$. ratio magnetic energies may play key role
