The Riverboat Return and the Snuff Bottle Breakthrough
Qi Menglin wakes after spending a full day and night unconscious from his river ordeal. Luo Su stays right beside his sickbed throughout the vigil, prompting him to feign a lingering lack of appetite just to prolong her company. As they board the boat back to Linfen, their banter carries genuine emotional weight.
"I would rather you owe me a debt. That way, I will always have the reason and the strength to seek you out, wherever you go under the skies."
Linfen County faces an engineered crisis orchestrated by Song Kun and Wu Zhuangyuan to frame Magistrate Han Muzhi for judicial misconduct. In court, Wu Zhuangyuan mounts a seemingly airtight alibi, presenting corrupt local clerks and bribed herbalists who claim he was bedridden with illness.
Luo Su dismantles this defense through material testimony. Witnesses from the Hejin jail independently described an instigator repeatedly inhaling from a miniature bottle featuring an exotic blonde portrait. Luo Su demonstrates that this rare Western snuff bottle belongs exclusively to Wu Zhuangyuan across both jurisdictions.
Han Muzhi backs her deduction by trapping the compromised senior clerk Wei Dianli at a local tavern, forcing a full confession between administrative ruin and total familial purge. The public collapse of Wei Dianli secures a clean exoneration for the magistrate while establishing order in the yamen.
Rejecting the Concubine Trap for the Bailiff Badge
The resolution of the courthouse frame-up reveals the harsh bargain behind Luo Su's legal release. Liu Wan had delivered the emancipation certificate to Han Muzhi under a punitive condition designed to trap both parties.
"If you insist on taking her into your household, she can only be a lowly concubine. My noble standing will never tolerate a broken engagement, so choose between your family alliance and her freedom."
Liu Wan expected Luo Su to either become a powerless concubine subject to inner-quarter abuse or remain trapped in social limbo. Han Muzhi surrendered his personal affections to secure Luo Su's papers unconditionally, granting her self-determination rather than domestic ownership.
"Starting tomorrow, you are an officially registered bailiff of Linfen County."
Luo Su accepts her registry documents but refuses a quiet civilian retirement. Instead, she requests an active post as a field investigator. While minor clerk positions carry little glamour, holding an official title gives her sovereign authority over her own movements and intellect.

The Walled Compound Ambush and the Confidante Blunder
Luo Su's new position is tested immediately when she mediates a violent water rights clash between neighboring farming communities. While returning in dust-streaked clothing, she is ambushed and abducted by Liu Wan's retainers, who accuse her of violating their unspoken pact by staying near the magistrate.
"My clothes were disheveled because I was pulling brawling villagers apart. Doing honest work with my own two hands every day is the life I truly want."
Qi Menglin discovers her absence and frantically scours the area despite his unhealed injuries. Tracing her scent to the estate of Lady Lin, Liu Wan's married cousin, he scales the perimeter wall, only to be tackled by guards, bound in ropes, and sentenced to a severe public caning as an alleged thief.
With Lady Lin's household gathering to investigate the intruder, Liu Wan panics over the risk of exposure. Luo Su leverages the household's delicate internal hierarchy to flip the situation.
"This gentleman came here looking for me, and I am the young lady's close personal confidante."
Appearing in elegant silk garments, Luo Su rebrands Qi Menglin as her personal caller and claims an intimate friendship with Liu Wan. This quick-witted lie halts the beating, saves Qi Menglin's life, and forces Liu Wan into an awkward silence to protect her own family standing.
Faction Clashes and Narrative Trajectories Ahead
The resolution of the snuff bottle conspiracy settles Wu Zhuangyuan's immediate scheme, but it leaves several dangerous power dynamics active across the region:
- Governor Liu's Looming Backlash: Even though Wei Dianli confessed, his patron Governor Liu still controls judicial leverage over Han Muzhi's magistracy.
- Liu Wan's Humiliation: Having her kidnapping thwarted and being forced to accept Luo Su as a nominal social equal leaves Liu Wan searching for harsher retribution.
- Qi Menglin and Military Reinforcements: Qi Menglin's determination to shield Luo Su pushes him closer to utilizing his familial ties with the Pingyang garrison, setting up future official friction.

Frequently asked questions
Why did Luo Su choose to become a bailiff instead of accepting concubine status?
Luo Su refused to exchange her newly acquired emancipation for a life of subservience. Entering Han Muzhi's household as a concubine would leave her vulnerable to Liu Wan's domestic control, whereas serving as a county bailiff allows her to pursue justice and support herself through her own skills.
How did the Western snuff bottle expose Wu Zhuangyuan in court?
Jail witnesses from Hejin testified that the instigator carried a distinct flask featuring a blonde portrait. Luo Su demonstrated that this foreign luxury item belonged solely to Wu Zhuangyuan throughout the Linfen and Hejin jurisdictions, completely destroying his fabricated illness alibi.
Why was Qi Menglin captured and bound in Lady Lin's compound?
After discovering that Luo Su had been abducted while mediating a village dispute, Qi Menglin scaled the compound wall to rescue her. The estate servants caught him trespassing, assumed he was a common prowler, and prepared to cane him until Luo Su intervened.
How did Luo Su save Qi Menglin from the household guards?
Luo Su quickly changed into fine garments and presented herself as Liu Wan's close personal companion. By claiming Qi Menglin was visiting her, she stopped the punishment and trapped Liu Wan into playing along to avoid social disgrace.
