A jobless weapons-engineering graduate binds a God-tier Origami System, livestreaming paper rifles that shock the nation. Banned at his peak, he’s secretly recruited by the National Arms Institute, unlocking anti-tank mines, rocket launchers, and more folded-paper firepower. From nobody to a hidden military ace, he becomes the sharpest weapon behind national defense.

The protagonist, Chen Wen, attracts the attention of the Capital City Police Department due to suspicions of manufacturing firearms during a Douyin live stream. The Capital City Police Department sends a request for assistance to Jingling City, where Chen Wen is located. Director Zheng and Criminal Investigation Captain Liu Bo of the Jingling Police Department attach great importance to this case. Although initially disbelieving, after reviewing the video evidence, Director Zheng immediately orders the deployment of the SWAT team to apprehend Chen Wen. However, when Liu Bo leads his team to intercept Chen Wen, who has just returned from shopping, at the entrance of his residential complex, Chen Wen remains unusually calm and cooperative, leading the police to initially assess him as non-threatening and cancel the SWAT support.

Protagonist Chen Wen is taken in for questioning by Criminal Investigation Captain Liu Bo for using paper to make a gun during a live broadcast. The police are shocked to find a paper assault rifle in his home. During the interrogation, Chen Wen explains his actions were to apply for a job at China Ordnance Industries Group, his absurd reason leaving the detectives speechless. However, just as the police contact the Beijing police station to verify the situation, the 208 Research Institute of the Ordnance Group surprisingly approaches them, confirming they were indeed looking for Chen Wen, leading to an unexpected turn of events.

Genius youth Chen Wen, who gained attention for creating guns out of paper, has his whereabouts pinpointed by the 208th Research Institute of China's Arms Industry Group. The security department of the 208th Institute quickly takes action, obtaining information from the Beijing Police Department and learning that Chen Wen is at the Jingling Police Station. Professor Lin Yongming, the chief designer of the Type 191 firearm family, attaches great importance to this matter, believing Chen Wen to be a key talent capable of advancing the nation's firearms technology. He immediately decides to fly to Jingling with his student Zhou Yuchen to recruit him. Meanwhile, Liu Bo, the captain of the Jingling Criminal Investigation, undergoes a complete 180-degree shift in his attitude towards Chen Wen after receiving instructions from his superiors, now treating him as an honored guest.

After being cleared of suspicion, protagonist Chen Wen is politely asked to stay at the police station by criminal investigation captain Liu Bo, to await an important figure from the "Weaponry Industry Group" in Beijing. After hours of waiting, the visitor turns out to be Professor Lin Yongming, a leading authority in firearms design, and his student Zhou Yuchen. Chen Wen is shocked to discover that this prominent figure is none other than the idol he greatly admired during his university days. This unexpected meeting marks the beginning of Chen Wen's extraordinary talent being discovered and recognized.

This episode details the first meeting between firearms design genius Chen Wen and Professor Lin, an expert from the 208 Research Institute. Professor Lin greatly praises Chen Wen's design talent showcased in his online videos and is curious why he didn't apply to the Arms Industry Group back then. Upon learning that Chen Wen was rejected due to fierce competition, Professor Lin formally extends an invitation to him. To continue receiving rewards through his "system," Chen Wen accepts the invitation while also proposing special working conditions to Professor Lin, citing his "research quirks" (live-streaming science popularization and origami).

This episode sees protagonist Chen Wen explaining his "quirks" of live-streaming creations and using origami to Professor Lin at the 208 Research Institute. He frames it as "Feynman learning" and system limitations. Professor Lin expresses understanding and successfully recruits Chen Wen into the 208 Research Institute by offering to help him restore his livestream, tasking him with assisting in the improvement of the 191 new firearm family. Chen Wen gladly accepts. Afterward, Professor Lin not only takes Chen Wen's paper rifle model for reference but also leverages his connections to have a student working on the Douyin platform unblock Chen Wen's livestream, clearing his obstacles.

Professor Lin's student, Xiao Zhou, worries that Chen Wen's livestreams will implicate his mentor. However, Professor Lin expresses full confidence in Chen Wen and has paved the way for him. Meanwhile, Chen Wen is pleasantly surprised to find his livestream account unblocked, officially verified, and boasting millions of followers. Greatly encouraged, he decides to seize the opportunity and immediately begins preparing for his next livestream: making anti-tank mines. Remembering his promise, he takes precautions to handle the core components in advance to prevent leaks.

After being banned for live-streaming gun making, protagonist Chen Wen is unblocked through Professor Lin's connections and embarks on a bolder "landmine making" live stream. This sparks excitement among fans and new viewers, causing his popularity to soar and online viewership to quickly exceed one hundred thousand. He Zong, an executive at the Douyin platform, notices Chen Wen's immense traffic value and sees it as a prime opportunity to surpass competitors. He orders the technical department to give Chen Wen's live stream maximum promotion, pushing the event to a new peak.

He Zong, an executive at the Douyin platform, decides to take a risk and promote streamer Chen Wen's hardcore live stream in a bid to defeat his rivals. Despite his subordinates' concerns about the potential legal risks of his live stream content (making landmines out of cardboard), He Zong overrides their objections and takes personal responsibility. Meanwhile, Chen Wen's live stream gains immense popularity, attracting many entertainment seekers and students from military engineering majors. However, due to the tedious production process, the online viewer count struggles to break the system's requirement of one million. After completing a crucial component, an exhausted Chen Wen begins interacting with the audience, explaining how his cardboard anti-tank mine is designed to evade mine detectors.
