Reincarnated as The Second Son of the Richest Man: The Whole Family Turned Villains

Lu Xingheng transmigrates into the body of the second son of Yuncheng's wealthiest family, a character destined to become a cannon fodder who steals documents, causes his family's bankruptcy, and dies in prison. Upon waking under his older brother Lu Yun's bed, he discovers the document he intended to steal is merely a physical examination report, averting the immediate crisis. Lu Yun, a cold and ascetic family patriarch, forgives him after a tense confrontation and deposits one million into his account. Lu Xingheng resolves to prevent the Lu family's downfall within the next hundred days, uncover the truth behind his parents' murder, and keep the novel's male lead, Ning Tianyi, away from his siblings to avoid their tragic fates.

At school, Lu Xingheng attempts to mend his relationship with his younger sister, Lu Xingrou, who is destined to become a love-obsessed villainess. He intercepts her from meeting the male lead, but later discovers she is secretly communicating with Ning Tianyi and burning evidence, harboring a dark intent to kill her own brother. Meanwhile, Lu Xingheng confronts Meng Jiao, the male lead's future ally, who maintains a facade of perfection while subtly manipulating social dynamics against him. The tension escalates when a classmate, infected by a Pseudo-Human parasite, attacks Lu Xingheng under the wisteria trellis. The creature reveals itself as a mimic with compound eyes and sharp fangs, driven by an obsession with Lu Xingheng's scent.

Lu Xingheng defeats the mimic by shattering his expensive diamond watch and using the shard to destroy the creature's eye, saving his life but sustaining severe injuries. Lu Xingrou witnesses the aftermath, and agents from the Seventh Special Affairs Bureau arrive to handle the incident. Lu Xingheng is hospitalized, where he learns that the Bureau covers all expenses and manages the cover-up. He recognizes the team leaders, He Sheng and Gu Yumeng, as characters destined to die or retire early in the original plot, prompting him to reconsider his passive approach. The appearance of Pseudo-Humans is accelerated, indicating that the timeline has shifted due to his interference.

As Lu Xingheng recovers, he realizes the original host's stupidity was a cover for a deeper conspiracy. The Lu family's bankruptcy was not caused by a simple theft but by a systematic dismantling orchestrated by external forces. Lu Yun's scarred hand and cold demeanor hint at a hidden past involving combat against Pseudo-Humans. Lu Xingheng decides to actively investigate the source of the parasites and the mastermind behind the family's ruin. He begins to train, leveraging his knowledge of the future to gain an edge. The story shifts from a survival drama to a strategic battle against supernatural threats and human conspirators. Lu Xingheng must navigate the dangerous world of the Seventh Bureau while protecting his family from the encroaching darkness.

The narrative introduces the concept of Pseudo-Humans as ancient parasites that have lurked in society for centuries. Lu Xingheng's unique scent makes him a target, suggesting he may have a special connection to these creatures. Lu Yun reveals glimpses of his own abilities, hinting that he has been fighting these entities in secret. The relationship between the brothers evolves from distant and suspicious to a tentative alliance. Lu Xingrou's dual nature becomes a central mystery, as she oscillates between affection for her brother and devotion to the male lead. Lu Xingheng must determine whether she can be redeemed or if she is beyond saving. The impending college entrance exam serves as a deadline for the family's destruction, adding urgency to his mission.

Lu Xingheng's investigation leads him to uncover a network of individuals manipulating the Lu family for their own gain. Meng Jiao's role in the conspiracy becomes clearer, as he uses his charm and intelligence to isolate the siblings. The male lead, Ning Tianyi, emerges as a powerful figure who exploits Pseudo-Human incidents to rise to prominence. Lu Xingheng recognizes that preventing the plot requires more than just avoiding key events; he must dismantle the entire system that supports the original storyline. He begins to gather allies within the Seventh Bureau, aiming to change the fate of those destined to die. The story builds towards a confrontation with the primary antagonist, who seeks to use the Lu family's wealth to unleash a greater catastrophe. Lu Xingheng's journey transforms him from a passive observer into an active participant in the war against the Pseudo-Humans.
