'Look like I needed to learn the technique that is used by those people from other planets who came to Eden Blue.
I think only that technique did not have this kind of restriction. Other than that I did not have any other way to bring my grandparents and my aunty to Eden Blue.'
Naturally Sam wanted to bring his grandparents and his aunty to his planet. Using the World bridge technique that he knew would not be able to help him in this matter.
His grandparents would not be able to tolerate all The spiritual fluctuation created by the space. Sam is thinking about this matter.
At this time, he also became very curious about the way that he went to Eden Blue. Unfortunately his grandparents did not know anything.
Sam even decides that he will go to that place from where Hina travels to Eden Blue. What if some kind of clue is present in that place?
