Gawain didn't know what kind of changes happened to his soul, but he was sure that his soul had already transformed completely when he transmigrated. Otherwise, there was no explanation as to why a person could remain in the sky for millions of years and still remain sane. Furthermore, it wasn't just a sane state of mind, he also had a clear memory. The horrific and massive amount of data that he had collected from millions of years of observation had actually been preserved in his memory; it didn't have any damage and was unscathed. Even until now, Gawain could still accurately retrieve the data.
However, there was something certain: the souls of the Eternal Sleepers' followers obviously didn't go through such reformation.
In just a few short seconds from reading the massive observation data, it caused a destructive impact to the heretic who still had a fundamentally human soul.
