Lin Mu returns to the age of eighteen, just after the college entrance exam, before everything has even begun. In his previous life, he experienced firsthand which stocks would rise, which emerging trends were about to take off, and all the insider knowledge that others would have to pay a fortune to obtain. In this life, that knowledge is his trump card for crushing the competition. With 100,000 yuan in starting capital, he dives into crude oil futures. His three roommates all find their own paths to success with Lin Mu's help: a genius who codes his way to a trillion-yuan valuation, a private equity heir who watches candlestick charts until he gets wiped out, and a grassland man who only wants to play video games. Together, they make strides in finance, real estate, food and beverage, and technology, with Lin Mu getting ahead of everyone to seize every emerging opportunity.
