Previously, the reason that Sebastian ended up being able to wake up from his deep trance was because his main energy core had been filled to the brim with spiritual energy by the fire spiritual energy that had been constantly entering into his main energy core while his sun energy refining technique was revolving.
As soon as Sebastian's main energy core was filled to the brim with spiritual energy, a weird feeling immediately appeared in Sebastian's dantian, causing Sebastian to open his eyes and regain his consciousness.
As for what that weird feeling was…
To Sebastian, it felt as if his main energy core had been enveloped by an invisible barrier, and that invisible barrier was preventing his main energy core from being able to expand furthermore than it already had expanded.
"So… this must be what the so-called "cultivation bottleneck" that everyone always talked about is…"
