Weak Water

In order to prevent the weak water from flooding the world, the dragon princess volunteered to cut out her heart to calm the river. Thousands of years later, she discovered that Ruoshui was actually the suppressed fiancé's soul - he took the blame for her flood and sweetened the poisonous water. When she smashed the river-suppressing monument, he used the last of his power to push her back to the bank: "There are three thousand weak waters, but only one of your ladles has scooped them for me." When the water receded, countless copper bottles appeared at the bottom of the river, each engraved with the chronology of the dragon clan diluting the weak water with their blood - it turns out that the so-called suppression is the use of love to turn poison into rain from generation to generation.
