The Doppelganger And Invisibility Unique Skill!

Entering the Sea King Inheritance ground was a life-changing encounter to Sebastian, it was an encounter that changed his story for good.

Inside the inheritance ground, Sebastian chewed on mana cores and even the natural cores like candy, he fulfilled a pivotal goal by evolving to the purple tier, he learned a lot of priceless information, but still, all these gains could not compare to one of them.

Getting his 2nd unique skill trumped all these gains by a sizeable margin.

For a long time after he transmigrated into this world and after the unique skill hunter mission was revealed to him, Sebastian made hunting for these special priceless skills his main goal alongside his ultimate dissection ambition.

To achieve this goal though, Sebastian could guess the threats involved and easily decided to stay prudent and to accumulate strength first.
