  Slowroll after tunneling is a crucial step in one popular framework of the
multiverse---false vacuum eternal inflation (FVEI). In a landscape with a large
number of fields, we provide a heuristic estimation for its probability. We
find that the chance to slowroll is exponentially suppressed, where the
exponent comes from the number of fields. However, the relative probability to
have more e-foldings is only mildly suppressed as $N_e^{-\alpha} $ with
$\alpha\sim3$. Base on these two properties, we show that the FVEI picture is
still self-consistent and may have a strong preference between different
slowroll models.
