The Greatest Warrior of All Time Returns - Chapter 51

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.

A world where awakened individuals with special powers emerge due to a system. At the New Spring Kindergarten infant class, Gru awakens as an S-rank Hunter at the age of 4. Along with this, there is a quest assigned to her… [Quest: A child needs a strong guardian!] Why is a guardian needed? That is because Gru has no mother or father. Gru, who had no family, is adopted by the greatest Hunter in South Korea after many twists and turns, and along with that, new skills are developed… [Let’s try registering a new guardian in the slot!] [Children can earn ‘filial piety points’ through various activities, which can be used in different areas.] Gathering guardians enables faster growth? ‘That’s amazing!’ Alright, I’ll gather all the S-rank guardians!
