I invested my expertise to revive a hundred acres of seemingly doomed shrimp ponds. But just as peak season arrived, Wang Hai and his wife discarded me after using my skills, slashing my promised 800,000-yuan profit share to a mere 100,000 yuan in compensation for my hard work. I smashed the water-treatment chemical tanks, took my technical notebooks, and walked away. To save on electricity, they shut down the aerators and switched to low-quality feed. When white spot disease broke out during the rainy season, all the shrimp and crabs across the hundred acres perished, leaving them with a devastating loss of two million yuan. Desperate and out of options, the couple knelt before me late one night, begging me to save their business. I flatly refused and went on to raise premium aquatic products in a new reservoir, while they ended up divorced, buried in debt, and struggling to make ends meet.
