No. That's no it. Thank you. For your help. But I found it. I went through all of the manga. It was "Constellations Are My Disciples". Thank you for help. :)
No problem. Glad you found it anyway
I been trying to look for this manga. But I only remember part of it.
He was transmitted or went back to Earth, digging his treasure and different location.next part was. this girl and her brother/cousin were doing a test but the cousin/brother use dark magic ( I think)
That's all I remember.
