Tomb Robbers’ Chronicles: Any Angsty Stories Where the Protagonist Saves Everyone but Himself? 盗笔，有没有虐文，救了所有人却不救自己

Looking for something like The Grave Robbers' Chronicles: Dual Birth of Yin and Yang. The protagonist knows everyone's fate and tries desperately to save them from the start. They're extremely powerful, have a special bloodline, and don't care about their own well-being. They use their own blood without hesitation, save everyone else but themselves, and the story is absolutely heartbreaking.
