In a fictional business competition story, a character who destroys the reputation of an opponent by spreading rumors can follow the following framework. Here, take the technology industry as an example to construct a complete plot.： **Story background：** "Dark Blue Technology" and "Star Obsidian Intelligence" are competing in the field of AI medical imaging diagnosis. The villain Lin Shen (CEO of Dark Blue) planned a systematic public opinion war to stop Xingyu's IPO plan. **The first stage: intelligence collection and weakness positioning (paving the way)** 1. Lin Shen bought a former laboratory assistant of Xingtai to obtain a vague record of its data labeling process in 2019. 2. Forged a PDF containing the words "85% data fraud" by hackers to imitate the electronic signature of the CTO 3. Anonymously broke the news in an industry forum: "The training data of a cutting-edge AI medical company has an astonishing water content." **The second stage: Multi-dimensional rumor matrix (upgrade)** 1. **Technical level**: Hired navy disguised doctors to complain at the Lilac Garden Forum that "the Star Obsidian system mislabeled malignant tumors as benign" 2. **Financial level**: The short-selling report of "Star Obsidian B round financing data has increased by 3 times" was distributed on <url> through overseas servers. 3. **Ethical level**: Falsifying a protest video of an environmental protection organization, accusing Xingyuan Yunnan data center of destroying rare plant communities **The third stage: grafting real events (combining reality and reality)** 1. "The CTO of Star Obsidian said at the technology summit that "there is no perfect medical AI", edited into "Our system is fatally flawed". 2. When a misdiagnosis accident occurs in a top three hospital (it has nothing to do with Xingji), immediately buy the hot search topic #Xingji AI kills patients 3. Use Deepfake to generate fake news conferences, showing that the CEO admits that "there are ethical loopholes in the system" **The fourth stage: systematic dissemination (detonation)** 1. Simultaneously publish a series of articles on "Qidi Xingda Capital Bureau" through 22 zombie public accounts 2. In Zhihu Manufacturing Wanzan answered, using professional terms to analyze "Why Xing Obsidian's technical route is destined to fail". 3. Buying key people: A distant relative of the FDA examiner revealed to the liquor bureau that "Star obsidian certification may be revoked" **The fifth stage: manufacturing internal cracks (patching knife)** 1. Fake headhunting emails were sent to the core team of Xingyu in bulk, suggesting that the company is about to lay off workers. 2. Post a screenshot of the chat history of "a VP of Xingmai accepts rebates" in the anonymous area of the pulse 3. Arrange for commercial spies to deliberately leak fake news that "venture capital is preparing to divest" on the board of directors **Key turning point design：** -Xing Obsidian cleaners found draft forged documents left by the printer -The sky outside the window in a breaking news video does not match the claimed shooting date -The monitoring of the hospital on the day of the misdiagnosis accident showed that the star system was not activated. **Finishing mechanism：** 1. On the 37th day of the spread of rumors, the Internet Information Office launched the "Qinglang·Special Remediation of Commercial Slander" 2. The blockchain depository company verifies that the MD5 code of all "evidence" documents is abnormal. 3. Lin Shen was arrested for the crime of sabotaging production and operation, and Dark Blue's stock price plunged by 40%.% **Narrative skills：** 1. Enhance realism with technical details: When describing forged PDFs, emphasize "create metadata with the 2018 version of Adobe" 2. Set the time pressure: the countdown to the Star Obsidian IPO is advancing synchronously with the speed of rumors. 3. Retain moral grayscale: Let the villain team struggle with conscience, and a hacker leaves a back door because his mother benefited from Star Obsidian technology. This structure not only shows the complexity of modern commercial warfare, but also warns of the destructive power of technology to do evil. The key is to embed every rumor in real industry pain points (such as the ethical controversy of medical AI), so that the fictional plot has a sense of reality projection.
