Honkai Impact: the Herrscher Born in the Sea

(No heroine) The silent sea surges in an instant The souls in the sea will set sail here Collapse... A desperate disaster ***: Against Honkai... Can we... Really win... Miracle, when will it come? Civilization collapses, the world dies This is reality, miracles do not exist... A miracle, a "Herrscher" was born from the sea. He knows his "past", he knows his "future", a person from another world who has traveled through time... Do you really know everything about yourself... (The introduction is very weak, let's read the text) (I would like to reiterate that this is a fan work from MiHoYo's Honkai IP. It is located in the world of Shuhai. The world where the protagonist is located is neither Honkai San nor Bengtie, but a completely different universe. The humble author will use the settings of Shuhai as the basis to create a brand new story. I would like to reiterate that if familiar people or objects appear, they will be counted as the same body.)
