Transmigrate as a Noble Consort with a System: The Emperor Spoils Me Rotten

[One True Pairing + Sweet Romance + Transmigration + System] Tang Wan was about to get promoted. She went out for a celebratory meal, only to run into a love-struck fool who was about to throw herself into the sea for love. Tang Wan failed to talk her out of it and ended up losing her own life trying to save her. When she woke up again, she had gained a System and been made a noble consort. Before she could even celebrate, she was told: “You’re in debt, dear! Saving you used up all 588’s energy, so 588 is going into hibernation now. But I’ve left you with a sub-System that you can still use!” Fine, so she’d just lost her little sprite. The System’s functions were still there. But why was the sub-System so “stupid”?! Tang Wan was at a loss for tears. In a fit of anger, she tried to flip the script. Flip, flip… Since she couldn’t manage it, she chose to lie flat. This is the story of Tang Wan transmigrating to ancient times, making friends and finding love, face-slapping cannon fodder, and striving to climb the ranks.
