Transmigrated into a Brain-Dead Cannon Fodder Female Character, I Decided to Lie Flat

Shen Mianmian, a modern woman, transmigrates into the body of a cannon-fodder courtesan in the novel After Rebirth, I Dumped My Scumbag Husband and Married the Regent Prince. She awakens on her wedding night with Bai Qingzhou, the foolish heir of the Marquis of Anning, who is destined to be the male supporting character obsessed with a transmigration heroine. Shen Mianmian realizes she is trapped in the book and learns from a voice in the thunder that she can return to her original world only when the novel's plot concludes. Her primary goal becomes surviving the household intrigue and ensuring the story reaches its ending so she can escape.

The novel's female lead, Jiang Yinjin, has been reborn with memories of her previous life. In her past existence, she was humiliated by Bai Qingzhou and the transmigration heroine, leading to her tragic death. Now, she seeks revenge by destroying the Marquis estate and aligning herself with the future Regent Prince. Jiang Yinjin expects the original plot to unfold with the courtesan causing chaos, but Shen Mianmian deliberately subverts these expectations. Instead of fighting for status or inciting conflict, Shen Mianmian accepts a low-ranking concubine position and behaves with submissive obedience, confusing Jiang Yinjin's schemes.

Jiang Yinjin attempts to manipulate Shen Mianmian into becoming a rival by offering to raise her status and suggesting she compete for the heir's favor. Shen Mianmian sees through these tactics and instead challenges the heroine's fabricated stories about historical courtesans marrying scholars, exposing the logical inconsistencies in Jiang Yinjin's plans. Realizing that Shen Mianmian will not be provoked into causing trouble, Jiang Yinjin shifts her focus to gaining the trust of Madam Ding, the matriarch of the estate, to accelerate her political maneuvering against Prince Jin.

Bai Qingzhou, initially infatuated with Shen Mianmian's unconventional modern views, becomes confused and hurt by her sudden change in demeanor. He confronts her about her rejection of his promises of monogamy, but Shen Mianmian maintains her distance to avoid becoming a target in the household war. Despite her efforts to create distance, Bai Qingzhou's erratic behavior forces Shen Mianmian to constantly manage his actions to prevent him from disrupting the main storyline. She narrowly avoids disaster when he attempts to consummate his marriage with Jiang Yinjin out of spite, eventually calming him down by feigning interest while ensuring he does not cross the line.

As the story progresses, Shen Mianmian is summoned by Madam Ding for punishment after Bai Qingzhou demands her rank be raised. Utilizing her knowledge of ancient superstitions, she performs an elaborate oath to prove her innocence, successfully deflecting the matriarch's anger. Throughout these events, Shen Mianmian remains focused on her ultimate objective: navigating the dangerous political landscape without altering the core plot points that lead to the Regent Prince's rise and the novel's conclusion. She must balance her survival against the relentless ambitions of a reborn heroine while managing the emotional volatility of her naive husband.

The tension escalates as Jiang Yinjin recognizes that her traditional methods of sowing discord are ineffective against a concubine who refuses to play the game. She begins to suspect Shen Mianmian might also be reborn, given the drastic changes in behavior. Meanwhile, Shen Mianmian discovers that her beauty, while advantageous for survival, attracts unwanted attention and complicates her attempts to remain inconspicuous. The narrative follows her strategic avoidance of key plot triggers, such as the rebellion of Prince Jin, while she waits for the story to reach its natural endpoint.

Bai Qingzhou's internal conflict deepens as he struggles between his affection for Shen Mianmian and his duty to his wife. His visits to Peony Courtyard and subsequent retreats create a volatile atmosphere that Jiang Yinjin exploits to further her own goals. Shen Mianmian remains an observer of the political machinations, carefully steering clear of the treasonous alliances Jiang Yinjin is constructing. Her journey is defined by the precarious balance between maintaining her cover as a submissive courtesan and ensuring the novel's romantic conclusion occurs, which is her only ticket back to the modern world.

The story concludes with Shen Mianmian still trapped within the narrative, having successfully avoided the immediate dangers of household warfare and political treason. She continues to endure the absurdity of her situation, relying on her knowledge of the plot to anticipate the moves of both the reborn heroine and the foolish heir. The path to her return remains uncertain, dependent on whether she can preserve the integrity of the original story long enough for the romance between the true leads to fulfill its destiny.
