The Stable Hanging and the High-Speed Cart Chase
Episode 22 opens with shock inside the Zhou residence when groom Wu Dali is found hanging in the stable. While the household attempts to treat his death as a straightforward suicide, concubine Xiao Yue moves quickly behind the scenes. She hires laborers to smuggle Dali's corpse out of the estate for a clandestine burial. Alerted to the suspicious transport, Zi Yan immediately notifies Luo Su and Liu Wan.
Without a second thought, Luo Su calls on Qi Menglin, who waits outside on horseback. Menglin spurs his horse into a rapid gallop to intercept the fleeing cart before the evidence disappears forever.

"Hold on to me tightly." — Qi Menglin
Thanks to Menglin's intervention, the magistrate's team recovers the body intact. Luo Su summons the imprisoned leader of the Xiangdang sect to examine the deceased. Looking at the corpse, the sect leader confirms Wu Dali's previous identity as his former disciple, Wu Lisheng.

"He was once a disciple under my sect, and his name was Lisheng." — Xiangdang Sect Leader
This identification brings past grievances into focus. Years earlier, Xiao Yue fell prey to the corrupt Xiangdang sect while desperately praying for a child. Dali recognized her secret and used it to subject her to relentless extortion. Xiao Yue had previously conspired with Dali to frame legitimate wife Xue Wenyi for adultery to secure her own position, but Dali's greed soon pushed her to the brink.
Forensic Revelations and the Incense Burner Trap
Gathering Zhou Xuan and the household members together, Luo Su breaks down the physical evidence from her examination of the corpse. The ligature marks encircle the neck horizontally rather than rising in an inverted V-shape, and blunt trauma marks mark the back of the head. These findings establish that Wu Dali was murdered prior to being hung up in the rafters.

"Wu Dali did not hang himself. This is a murder staged as suicide." — Luo Su
Suspicion immediately shifts toward Xiao Yue, who hired the corpse carriers. Panicked and furious, Zhou Xuan questions the lineage of their son and physically assaults her in front of the witnesses. Xiao Yue fires back, condemning his vanity and pointing out his own physical inadequacy.

"Did you never consider that you were the one incapable of fathering a child?" — Xiao Yue
While Xiao Yue admits to framing Xue Wenyi under Dali's blackmail, she adamantly denies striking the fatal blow. Luo Su notices discrepancies in the narrative. Knocking down a man of Dali's stature required a heavy metallic blunt object. Luo Su and Liu Wan stage an audible conversation within earshot of the courtyard, claiming the murder weapon must be a missing bronze incense burner.

"It is very likely the heavy incense burner that was kept in the room." — Luo Su and Liu Wan
That night, the investigation team catches someone sneaking in to dispose of the burner. The figure stepping out from the shadows is not Xiao Yue, but first wife Xue Wenyi.

"I killed Wu Dali." — Xue Wenyi
Xue Wenyi tearfully recounts what happened in the stable. Having overheard Xiao Yue and Dali conspiring against her, Wenyi offered Dali double the bribe money to clear her name. Instead, Dali attempted to assault her on the spot.

"I am doing this because I want you." — Wu Dali
During their struggle, Wenyi grabbed the nearby incense burner, struck him over the head in self-defense, and hung his unconscious body out of panic. Recognizing that Dali initiated the attack, Luo Su ensures the court records the act as justified self-defense rather than premeditated murder.
Zhou Xuan's Downfall and the Wind and Tree Dialogue
The resolution of the homicide exposes Zhou Xuan's moral bankruptcy. While boasting of scholar ancestry, he relied on his wife's family wealth to buy official recognition while abusing both women behind closed doors. Magistrate Han Mozhi delivers a swift ruling.

"Zhou Xuan's virtue does not match his office. As of today, he is dismissed from his educational post in Linfen County." — Han Mozhi
Despite uncovering the truth, Luo Su finds little joy in the outcome. She reflects on the systemic trap that forced two women in the same home to ruin their lives.

"We all lost. No one truly won this fight." — Luo Su
Liu Wan contrasts her position with Luo Su's independence, noting how Luo Su moves freely across boundaries while she must remain anchored to protect her family estate.

"You live like a gust of wind, free to dream. But I am like a tree, rooted to protect this corner of the world." — Liu Wan

Looking Ahead to the Finale
With the Zhou estate case concluded, the series sets up its final two episodes. Luo Su prepares to resign from the Linfen yamen to travel freely. Qi Menglin makes his loyalty explicit, promising to stand by her side across any landscape.

"Whether through the misty rains of Jiangnan or the northern desert dunes, I will go with you." — Qi Menglin
