Goddess of Ice; Reborn as Naruto's twin sister - Chapter 538: The Forgotten One

Because I like to collect antiques, I was accidentally brought to a magical world by a crystal skull in my collection.

- Description from novelbuddy

Ye Chen, once the unrivaled immortal standing at the pinnacle of the cultivation world, fell at the final hurdle—his last heavenly tribulation. Struck down by the wrath of the heavens, his body was destroyed, his cultivation shattered. Yet, instead of vanishing into oblivion, his soul defied fate itself.When he opened his eyes again, he was no longer in the vast cultivation realms but in the familiar yet distant world of modern Earth—inside the body of his younger self during his high school days. Armed with the knowledge and power of an immortal, he would rise once more, overturn destiny, and reclaim his supremacy in this new world.

Mochizuki Touya, a 15-year-old boy, who got zapped by a flash of lightning due to a freak accident caused by God, wakes up and finds himself face-to-face with God.

The Earth of the future is united under a single government, but not all things are well. The shape of the playing field may be changed, but the powerful still rule the weak.And those who do not conform with the rest of society are exiled to another world. A world that not even the technology of the future managed to tame.It should have been humanity's New World but ended up as nothing more than a penal colony. A place where the exiled are sent to die.Motivated by revenge, Magnus sets out on a quest to bring his own justice to his enemies. For that purpose, he is willing to go further than most others.But then he learns that if he truly wishes to change things, he can only find his answers beyond the gate.Having lived most of her life as an exile, Astra is a woman of few interests aside from survival and climbing the ranks of her clan.To achieve those goals, she certainly won't be squeamish when a chance literally falls into her lap, or will she?———————————————————————————————I am trying to go with a survival/“no modern tech” setting in this one. People from a technologically advanced society are thrown into a world where they can't maintain their tech. They are forced to rely on what the world provides where they have to make do with the limited resources they have and what little of their old technology is still working. Their gene manipulation allows them to have something akin to superpowers, but that doesn't help much against the monsters of their new world. Not sure yet whether sufficiently advanced technology will be discovered later on to count as magic.It turns more political between the various clans later on.
