Wang Yi gets a key, opening a door in 2022 will lead to 1982, and opening a door in 1982 will return to 2022.

Two very different great eras appeared before him:

Abundant dietary protection, developed industrial products, miraculous medicines, and explosive information, this is 2022.

Simple folk customs, rich wild resources, scattered antiques, and treasures of the age, this is 1982.

Traveling between these two eras, Wang Yi didn’t think much of it, he just wanted to live a good life.

- Description from novelbuddy

Set in a Pokéverse where the remnants of our civilization's Earth lie buried under the resurgent human/Pokémon societies, this epic Saga follows the protagonist through his journey to the heights of Pokemon Training and beyond, across a planet that was only saved from ecological disaster by an act of Arceus. As Humanity and Pokémon coexist in this fusion of settings, the story will explore themes of war, oppressive cults, and Shadow infusion, in a world where Pokémon healing and battles echo the anime in realistic, but not overtly graphic ways. Pokémon do not rip each other apart in Battles, though it can sometimes happen in the wild.This is a very long journey fic that's kind of a Crossover with everything. But with Pokémon. So you might see characters like Shaggy Rogers, or Izuku Midoriya, but with Pokémon teams. Pokémon legends like Red, Gary Oak, and the reigning World Champion, Ash Ketchum, are also, naturally, present in the setting. Think of this slice of the Pokéverse as one where it's all coming together.

Xu Xiuwen, who was battered and bruised, was reborn and found himself back at the farewell dinner after the college entrance examination. It was the year 2005. Facing the aggressive former love rival and the childhood sweetheart he once had a crush on, he decided to start a new life. After being reborn, he not only wants to recover the white moonlight that he missed in his previous life, but also builds his own business empire. Fame and fortune, career and love, he wants them all!

One day, spatial tunnels opened in the very fabric of reality, connecting Earth to a planet that came to be known as Xavier, a planet that has a lot of deserted settlements belonging to the civilization that lived on this planet before we started exploring it.

Each settlement not only hides a secret of its own but also treasures, knowledge, and unthinkable technologies.

In this new world, magicians rule the world and make the rules.

They are those who can contain magic energy, an energy source present in Xavier, in their bodies.

This energy is used to mainly empower supernatural cells.

One can get them by consuming evolution materials.

These supernatural cells suck magic energy to manifest one's superpower in the real world.

Elliot, once the son of magicians in the channel opening stage, now lives the life of an orphaned and poor boy.

Elliot is the weakest magician to ever exist in the world, a world where the strong are respected and the weak are disdained.

With the death of his parents, the ones who used to look down on his has no reason to control their feeling.

With a dim fate ahead of him, he grits his teeth and silently moves on to the day the light of glory shines on him, setting him apart from others in a single day, letting him taste what it means to be God!
