Genshin Impact: Terrarian Revolution

It had been over three months since Keston found himself thrown into a world based on a game he played in the past, and to make matters worse, it so happened that the world he was isekaied to had none other than the Calamity mod installed. Cause you know, he really wanted that extra danger to his life...

In any case, with determination and a whole lot of manual fucking labour, Keston had been managing to survive the countless dangers in the world. From defeating beings such as the King Slime, Desert Scourge, and more. All of which he did entirely on his own.

However, miracles do seem to happen as he suddenly gains the ability to cross between both this chaotic world and another. With an entire world to his name, just what massive changes will occur within the continent of Teyvat?
