Background / History

Transmigration and First Operations

Shen Yan was a modern office worker burdened by overtime, rent, mortgage payments, and a car loan. He transmigrates into an impoverished Shanghai patrolman of the same name after the original body is knocked unconscious by an ox cart. He inherits the patrolman’s memories and awakens in Japanese-occupied Shanghai in the twenty-sixth year of the Republic 1 2.

His first intervention is the rescue of Su Wan, an injured underground Communist courier. He hides her, misdirects Japanese pursuers, and gives her medicine that rapidly heals her gunshot wound. The resulting reward opens his system shop. After purchasing combat training, he kills his abusive superior Wang Panghai with the system’s brick, conceals the body in a dry well, and takes his pistol 2 3.

Shen Yan subsequently protects a pingtan performer from Green Gang thugs and defeats the retaliating Scarface Liu. These incidents establish his reputation as a ruthless protector of the neighborhood. His conduct also wins the approval of veteran patrolman Old Chen, whom he formally adopts as his foster father during a drinking session 4 6 8.

Police Promotion and Resistance Contacts

When Su Wan seeks help for her wounded comrade A Yuan, Shen Yan discovers Japanese agents surrounding their hideout. He eliminates the surveillance team, removes A Yuan’s infected bullet wound, and warns that their organization contains a traitor. Su Wan and A Yuan subsequently leave Shanghai 11.

The appointment of Lu Tinghui introduces a more dangerous superior: Heavenly Eye identifies him as Japanese agent Watanabe Seiichi. Shen Yan survives his questioning with a system-protected backstory and receives a promotion. Using newly available equipment, he intercepts a Japanese document convoy and obtains a purge list naming 62 suspected anti-Japanese personnel. His warnings enable Communist and Military Statistics Bureau contacts to evacuate 14 15 17.

Lu later tests him by presenting Japanese agent Matsumoto Ichiro as a captured Communist. Once Shen Yan identifies the deception, he interrogates the agent brutally while maintaining his cover. Matsumoto dies afterward, while Lu interprets Shen Yan’s performance as proof of loyalty 19.

Family and Special Operations Command

Shen Yan intervenes when Wang Erlai attempts to sell his daughter. Old Chen arranges to adopt the girl into their household, with Shen Yan taking a paternal role. She is later renamed Shen Nian’an, expressing a wish for lifelong peace. Shen Yan buys a more secure courtyard home and gives her a puppy, Big Yellow 20 21 30.

After receiving a public security medal and 500 fabi for his contribution to the Drunken Immortal Tower operation, Shen Yan undergoes a month of Special Higher Police training. He graduates first and cripples Matsumoto Toru, who seeks revenge for his brother Ichiro’s death. Shen Yan then assumes command of the Special Operations Squad, including four Japanese trainees he had previously subdued 24 26 27 30.

Evacuation Cover and the Hongkou Arsenal

Shen Yan works to save a Military Statistics Bureau contact point targeted by his own police organization. The agents escape through a tunnel, while explosives inflict heavy casualties on Li Kui’s prematurely advancing force. The operation culminates in an apparent confrontation between Shen Yan and the masked Scavenger, leaving Shen Yan hospitalized but credited with wounding the fugitive 30 31 32.

While recovering, he sends his clone into the Hongkou arsenal in disguise. The clone plants explosives among artillery ammunition and leaves the signature “CLEANER.” Following the destruction, Shen Yan intercepts looted cultural relics and gold and deliberately creates the impression that the Scavenger is an organization rather than a single operative 33 34.

Xihengjing and Cherry Blossom Hot Springs

Forewarned of an attack on Hou Boquan’s guerrilla unit, Shen Yan prepares an ambush at Zhangjia Dachang. He equips the resistance with heavy machine guns and grenade dischargers, directs the fighting, and helps destroy the attacking Japanese and puppet troops. He distributes captured supplies and urges the guerrillas to evacuate nearby villagers before reinforcements arrive 37.

His conflict with No. 76 escalates when Li Bingkun has him followed and later places a secret bounty on him. Shen Yan turns the bounty into an ambush against Ma Yao, extracts a confession and ten large gold bars from Li, and earns a personal Green Gang token from the Great Master 42 44.

Shen Yan then establishes Cherry Blossom Hot Springs on Wusong Road in Hongkou. The business provides an explanation for his growing assets and Green Gang connections, reassures Kuroiwa Masao that he intends to settle under Japanese patronage, and secretly gathers conversations from Japanese guests through concealed copper listening pipes 45.

Harbin and the Destruction of No. 76

Sent to Harbin to investigate the Scavenger, Shen Yan uses his clone to maintain the appearance of studying official reports while he contacts the Anti-Japanese United Army. He exposes an infiltrator, supplies Commander Yang Chenyu’s forces, and enters Unit 731 disguised as Kobayashi Masao. He photographs the laboratory, opens prisoners’ cells, plants incendiaries, and signals the resistance attack before returning to Shanghai after quarantine 47.

Shen Yan later infiltrates No. 76 using Li Shiqun’s identity, with his clone disguised as Zhang Lu. He poisons 21 agents, frees 18 Communist and Military Statistics Bureau prisoners, removes files and weapons, and plants incendiary bombs. During the subsequent explosion, he shields Kuroiwa to reinforce his cover. He then hunts more than thirty agents named in the seized roster, helping render No. 76 defunct 50.

Appearance

  • Youthful body: Described as not yet twenty when confronted by Scarface Liu 6.
  • Lean, strengthened build: Basic Combat Mastery transforms his formerly scrawny, slack muscles into firm, defined musculature 3.
  • Head scar: A scar on the back of his head becomes a subject of Japanese scrutiny; he explains it through a fabricated account of a Communist ambush 24.
  • Deliberately timid bearing: Slouches, hunches his shoulders, lowers his head, and avoids eye contact to reproduce the original patrolman’s cowardly manner 1 4.

Personality

Shen Yan’s apparent cowardice is largely a survival performance. He readily acts submissive, awkward, poorly educated, or apolitical when dealing with Japanese officials, while privately assessing their weaknesses and protecting his freedom to act. During training, he deliberately moderates his results until a system mission requires him to graduate first 1 25 27.

His opposition to the occupation is accompanied by concern for vulnerable people. He initially saves Su Wan without expecting payment, refuses neighborhood protection money as disgraceful, and assists both Communist and Nationalist resistance personnel. Despite their interest in recruiting or meeting him, he prefers to retain his independence and route communications through Fang Yuan 3 17 20 41.

He is also opportunistic and unusually comfortable with violence against people he judges wicked. He treats enemies as sources of system points, experiments with repeated beatings to extract rewards, and reacts to Wang Panghai’s death with excitement rather than the fear he expected. His humorous internal commentary frequently frames dangerous operations as profitable work or voluntary overtime 1 3 4 10.

With his family, Shen Yan is affectionate and playful. He cares for Old Chen after drinking, promises Nian’an sweets, checks her calligraphy, and tells her stories until she falls asleep. Their household provides a private contrast to his police persona and clandestine violence 8 30 42 44.
