  We present a fully-kinetic simulation of the full life cycle of strong
Langmuir turbulence (SLT) excited by electron beams that are accelerated under
the solar corona conditions. We find that (1) most packets ($\sim$80%) are
affected by their neighbors during their collapse, as a result, their spatial
scale variations present non-standard evolutionary features, i.e., deviating
away from what was predicted by the Zakharov model; (2) the collapsing cavity
is too shallow to trap the wave packet due to the growth of the Coulomb force,
as a result a majority ($\sim$70%) of the packet energy runs away and a
secondary localization may occur. The study indicates that the non-standard
Langmuir collapse may play an important role in coronal plasmas interacting
with an intense electron beam, that may be eventually confirmed by humanity's
first mission to fly through the corona.
