After Crossing the Mad Imperial Preceptor, She Ruled the World

(Transmigration + pocket dimension + two equally powerful leads + sweet romance) Liuli dies trying to save her younger brother. At the same time, Chuxia, from the 21st century, dies unexpectedly and triggers the power of a pocket dimension, transmigrating to the Li Kingdom. The utterly ordinary Chuxia becomes Liuli, runs afoul of an unhinged Imperial Preceptor, and turns into a Grand Princess who can control the court and wield power over the realm. The unhinged Imperial Preceptor smiles like a spring breeze. “My Li'er, where else would you want to go besides my side?” Liuli thinks she's the one who flirted with the innocent Imperial Preceptor, but it turns out he's a wolf in sheep's clothing. “How is he innocent at all!” She thought she was the only one with a secret identity, but the person who dotes on her has one too. How will their relationship turn out in the end?
