Yeah, i believe Option 3 and 5 would lead to the most interesting outcome. As for the other options, it's just not in the interest of the readers (especially for me, going under ryuen is a very dumb plot).

While i know it's for growth and not make the MC so infallible but i still feel like the bs of how the mother died and just having her gone instantly is like, mate i know you want to make the soul and reincarnation power hard but MC could have anchors her soul and fix the body and infused them together. Reincarnation magic is either the hardest magic or just another type of support magic is really dependent on the author. But i think the way of overlord tier magic system where reincarnation isn't hard, and just becomes another magic type is a better power system (to me a human soul isn't worth infinite, you can see it on earth, where you are worth less than dirt to a person of a different nation)
