Sebastian's new system status dropped like a bombshell to him.
Once he saw his new status, his excitement knew no end as he celebrated like a mad Megalodon. No intruder was there to serve as a spectator, so he was free to express his joy in any manner that he deemed fit.
Of course, Sebastian didn't celebrate forever, he didn't have the luxury for that, he was still in a region that was infested with bloodthirsty predators that were ready to rip his face off. After celebrating to his fill, he finally calmed down.
This was when Sebastian started analyzing his new system status.
Everything that transpired after he regained consciousness was so unbelievable that he found them hard to believe, but they were true.
Sebastian first navigated back to his 2nd system notification after he regained consciousness, which was about how he fulfilled the requirements to access the Ocean King's hidden inheritance reward.
