Cheng Tianyi, a modern white-collar worker who is proficient in the Internet and business management, traveled to the prosperous Northern Song Dynasty after a car accident (in an imaginary background).
He was so excited that he firmly believed that the "high-dimensional knowledge" he had mastered would allow him to achieve great success immediately: making glass, smelting steel, engaging in marketing, and implementing scientific management. With the ambition to change the world, he started the grand "Dimensionality Reduction Strike" plan.
However, reality was like a basin of ice water, pouring him from head to toe:
He knew the principles of steam engines, but he couldn't even build refractory stoves and precise parts; he wanted to implement a market economy, but was hampered by the complex currency, logistics, and acquaintance society of ancient times; he wanted to use "efficiency" to persuade officials, but he was regarded as a fanatic who despised sages. Modern theoretical knowledge is useless without the support of ancient materials, techniques and systems.
From being the "Chosen One" to being an "ancient waste" who couldn't even make a fire to cook, Cheng Tianyi finally understood that ancient survival wisdom was far more practical than the PPT and Excel spreadsheets in his mind.
In order to survive, he had to give up the fantasy of subverting the world, learn traditional Chinese characters, farming, and worldly ways from scratch, and apply modern logic, mathematics, and dimensionality reduction to accounting and management that was acceptable in ancient times...
