My System Annexes Worlds To Save Teyvat

Ye Heng thought truck-kun meant an ordinary isekai adventure. Instead, he crash-landed directly on Sky Island, inheriting the mantle of Teyvat's Heavenly Law. Good news: he's suddenly an omnipotent god! Bad news: Teyvat is crumbling from centuries of abyssal erosion, ten years from total annihilation, and he's inextricably tied to its fate. His predecessor died trying to stave off this very collapse. Just as despair threatened to consume him, a god-tier \"Dimension Dominator System\" awakened. Its audacious solution? Annex and absorb entire other worlds! By devouring their unique laws, advanced power systems, and even their very essence, Teyvat can be miraculously healed, strengthened, and evolve into an eternal, supreme realm at the pinnacle of the multiverse. With worlds like Demon Slayer, Akame ga Kill, and Inuyasha now ripe for conquest, Ye Heng won't just save his new home—he'll transform it into the ultimate cosmic empire. But how will Teyvat's Archons react when their new Heavenly Law demands they help conquer other universes and sacrifice their own to his boundless ambition?
