He was also bound to a useless gossip System. It was the resource-scarce 1970s, and looking at his family, all gaunt and at risk of dropping dead at any moment, Jiang Le was close to breaking down. Until... When Auntie Zhang from next door came around to bully them yet again, the useless System suddenly got excited. “Host, Auntie Zhang’s husband is infertile!” Jiang Le looked at Auntie Zhang’s five sons and three daughters. “!!!” System: “Beep! Tell Auntie Zhang’s husband the truth and you’ll earn 100 Gossip Coins!” When the factory director tried to abuse his position to steal Jiang Le’s cousin’s job for his own niece, the System got excited again. “Host, the director is colluding with the purchasing manager to line their pockets! Expose him and earn 500 Gossip Coins!” When the educated youth who had a crush on the female lead spread rumors about Jiang Le, the System got excited once more. “Host...” Looking at the System’s shop, where malted milk powder cost just five Gossip Coins and a white-flour steamed bun cost one, Jiang Le felt like he was getting rich... From then on, while the original male and female leads struggled to get enough to eat, Jiang Le used the gossip he collected to buy White Rabbit candies, precious milk powder, and beautiful clothes unavailable even at the department store, raising his gaunt family until they were rosy-cheeked and thriving. The original leads kept breaking up and getting back together, scheming against each other. By the time they came to their senses, the little cannon-fodder Jiang Le they’d looked down on had gotten into Peking University! But Jiang Le had no time for them. He was still thinking about what had kept him reading that bizarre, worldview-shattering book in the first place. That dazzlingly talented person hadn’t even survived the winter. Jiang Le clenched his fists. He would make sure it didn’t happen again! But the more he protected that person, the stranger their gaze toward him became. Why? Theme: Strive with all your might
