But as the winds of destiny shift, new alliances must be forged, and forgotten powers awaken. What happens when the monsters of Tempest meet the Archons of Teyvat?

Rimuru Tempest, now at the absolute pinnacle of his power, stands as the revered leader of the Jura-Tempest Federation. He has seen it all: triumph and heartbreak, loyalty and betrayal, the rise of his nation, and the tragic price of war. But what if he could do it all over again? Ciel performs an unprecedented feat-sending Rimuru's consciousness back to the very moment of his reincarnation. This isn't a second chance; it's a New Game +. Armed with the wisdom of a god-tier being, the memories of a fulfilled future, and the power of a True Dragon, Rimuru must navigate the pitfalls he once faced as a naive, newly-reborn slime. This time, he won't be caught off guard by the schemes of Falmuth, Clayman, or the complex political machinations of the world. With his foreknowledge, Rimuru is determined to build a true paradise, a nation where no friend is lost and no sacrifice is in vain. But even with his immense power and knowledge, the past isn't so easily rewritten. New variables and unforeseen challenges await.
