Cultivating as a Nascent soul realm cultivator was… it was almost divine! His control over spirit energy had improved drastically, and that improvement carried onto other aspects of his cultivation as well.
The rate at which he absorbed Dragons Might also increased drastically, and that was before Pel gave him a bunch of exercises showing him how it was actually supposed to be used. He could feel himself improving, and that was after consciously trying to keep his actual cultivation from increasing. Fortunately, there were countless other areas he could improve in, so stopping a single aspect of cultivation was no burden.
