  We show a model of the slow expansion, in which the scale invariant spectrum
of curvature perturbation is adiabatically induced by its increasing mode, by
applying a generalized Galileon field. In this model, initially \epsilon << -1,
which then is rapidly increasing, during this period the universe is slowly
expanding. There is not the ghost instability, the perturbation theory is
healthy. When \epsilon \sim -1, the slow expansion phase ends, and the
available energy of field can be released and the universe reheats. This
scenario might be a viable design of the early universe.
