Modern Knowledge in a Chaotic World

Lin Huaijin wakes up to find himself as a starving, down-and-out scholar in an alternate chaotic era. Destitute and repeatedly failing the imperial exams, he is beaten and robbed by bullies, having not eaten a full meal in three days. In his dire straits, the 'Modern Knowledge System' activates—unlocking one piece of knowledge each day, starting from basic salt-making to mathematics, physics, medicine, chemistry, engineering, and then management, economics, and political science. A pound of crude salt trades for three liters of rice, and salt permits are the lifeline of the imperial court. He uses salt-making knowledge to earn his first full meal, uses mathematical calculations to set a trap and turn the tables on the bullies, and uses the principles of leverage to organize refugees for self-rescue. From a shabby temple in the slums to the powerful elite of Qingzhou City, from a starving scholar to a warlord in troubled times—this time, he will use modern knowledge to break through this chaotic world. — Description from novelcodex.org
