With Monte Carlo methods, we simulate the critical domain-wall dynamics ofmodel B, taking the two-dimensional Ising model as an example. In themacroscopic short-time regime, a dynamic scaling form is revealed. Due to theexistence of the quasi-random walkers, the magnetization shows intrinsicdependence on the lattice size $L$. A new exponent which governs the$L$-dependence of the magnetization is measured to be $\sigma=0.243(8)$.
