To Turn the Tables, I Was Born by My Nemesis

[Adorable child + female lead with no romance + mortal enemies become father and daughter + feel-good story] Immortals and demons are sworn enemies. Li Nuannuan, leader of the righteous path, was determined to eliminate demons and uphold justice. But her opponent was too powerful. She was reborn three times and never won once. So she took an unconventional path. And ended up as the “biological daughter” of her mortal enemy, who was in the middle of undergoing a tribulation. You never know until you try, and when she did, she was stunned. Before, whenever Li Hanjue saw her, he would strike to kill. Now, whenever Li Hanjue sees her, he bursts into tears. She falls down. Her father sheds tears. She doesn't eat much. Her father sheds tears. Nuannuan pouts. Her father sheds tears. What happened to the demon-slaying, murderous Demon Lord? Who is this crybaby in front of her?
