Genshin impact : Heaven's Will, Let Teyvat Become The Supreme World

Good news: I takumi have crossed over to Teyvat and become Celestia. Bad news: The Teyvat world doesn't have much time left. Good news: I have a system that allows me to annex two-dimensional worlds. Takumi looked at countless familiar worlds, tears of sorrow streaming down his face, and declared on the spot: "I am not only Teyvat's Celestia, but I will also become the Celestia of countless worlds." "Therefore, my rules are the rules." From that point on, a Celestia and a group of fierce and intimidating demon gods embraced each trembling world. Annexing the Demon Slayer world: Teyvat world's lifespan increased by 5,000 years, Lower Realm +1. Annexing the Akame ga Kill world: Teyvat world's barrier strength increased 100 times, Lower Realm +1. Annexing the Inuyasha world: Teyvat formed a cycle of the Underworld, Lower Realm +1. ... Until one day, a joyful Aeon from next door discovered the Teyvat world. Before they could take a look, countless hands slapped them, each resounding slap puffing up their face.
