We study the evolution of relic D3-branes after the $\mathrm{D}3/\overline{\mathrm{D}3}$-brane inflation in string warped compactification. The motion of D3-branes can be frozen under certain conditions during the radiation/matter domination. These D3-branes cannot be released until the $\mathrm{D}3/\overline{\mathrm{D}3}$-branes potential energy becomes dominated at late time. Subsequently, they will move towards to $\overline{\mathrm{D}3}$-branes, which play the role of uplifting AdS minimum to dS minimum, near the apex of throats. The annihilation of $\mathrm{D}3/\overline{\mathrm{D}3}$-branes leads to the disappearance of dS vacua. This process may be regarded as a rapid decay channel of present dS vacua. We discuss the parameter spaces required by this process and calculate the decay time.
