The powerup and him knowing where to go was kinda random, ngl. Wouldve made more sense if he had went back like 100 years ago or something so all the clues of "unclaimed" treasures, he wouldve been the one to get it first. Or, idk, using his memory of having been regressed from the future to his advantage. Or maybe this was a condition to activate his primodial vampire blood or some sht xD. Anything goes, I guess.
Just a casual reader binge-ing all interesting manhwas that I came across
