I Am Reborn as a Queen in the Palace

From the innocent girl in the Jiangnan water town to the ignorant promise in the deep palace, every step must be done on thin ice; fade away the youth, use wisdom to resolve the crisis, and win over the available people in the cracks; refuse to be bound by factions, use "purity" as a weapon, and maintain your true heart in the whirlpool of power; get involved in a deeper conspiracy, confirm each other in the test of life and death, and no longer back down.
