  Motivated by the recently proposed Trans-Planckian Censorship Conjecture
(TCC), we propose a gauged $B-L$ model of inflection-point inflation with axion
dark matter. The Hubble scale during inflation ($H_{\rm inf}$) satisfies the
TCC bound of $H_{\rm inf} \lesssim 1$ GeV, the axion dark matter scenario is
free from the axion domain wall and isocurvature problems, and the axion decay
constant can be larger than $10^{12}$ GeV. The seesaw mechanism is
automatically incorporated in the model and the observed baryon asymmetry of
the universe can be reproduced via resonant leptogenesis.
