I Rule the Three Realms by Begging for Food

In Shen Xiang's third year of cultivation, her spiritual roots were destroyed, her fortune stolen, and her memories of the past erased. She ended up in the demon realm. All she had with her was a tattered flag. Its blood-red cloth had torn into strips and drooped from the pole. It was incredibly ugly. But the more Shen Xiang looked at it, the more she loved it. Cultivators all have a personal spirit sword. Shen Xiang's personal spirit sword was this tattered flag. The tattered flag said it was hungry, so Shen Xiang went to find it food. She searched and searched, until she found Cang Li, the Demon Venerable. Shen Xiang: "Give me something to eat." Demon Venerable: "? Do you know who I am?" Shen Xiang: "I'm hungry. Give me something to eat." Demon Venerable: "..." The Demon Venerable took in a beggar fairy. This little immortal could really eat. The Demon Venerable wanted to abandon her, but gritted his teeth and persevered because she could at least help with his headaches. But one day, the Demon Venerable suddenly realized that this girl was actually feeding her cultivation to a tattered flag! Demon Venerable: "Throw that rag away, or I'll throw you away!" Shen Xiang hugged the flag close. "Don't underestimate it! When it unfurls, it'll save your life!" Demon Venerable: "...Why would I need it to save me?" Later, the Immortal Realm launched a campaign to exterminate the demons, and the Demon Venerable was besieged by immortal sects from every direction. At the moment of crisis, The dragon banner in Shen Xiang's hands billowed in the gale. A drop of scarlet blood summoned the souls of the dead, and an army of thousands appeared before them. Shen Xiang carried the banner on horseback, valiant and spirited. "Don't be afraid, husband. The soldiers and I are here to get justice for you!" As the blurb suggests: a powerful, tragic Demon Venerable male lead x a sweet, gloomy beggar female lead Beggar fairy: Begs Demon Venerable: Here, have some food. #Demon Venerable, you give me a bite to eat today, and tomorrow I'll bring an army of a hundred thousand to back you up# #It's a bargain!# Demon Venerable, stroking his empty wallet: "Shut up." When Heaven is about to place a great responsibility upon someone, it first makes them suffer hunger, hunger, hunger... Our thick-skinned female lead is a beggar who is bound to achieve great things.
