The Departure from the Original Contract

The protagonist is Zhongli. After the continent of Teyvat is destroyed, Zhongli sacrifices his status as a Demon God to protect Liyue. But because of his authority as the spatial ruler, he is sent to a timeline with no gods. Of course, other gods will join later, and there should be a space that allows him to stay in contact with Liyue. Note: Guizhong will be revived, but there will be a price. As for when she'll appear, take a guess.
