A history graduate student with a modern theoretical knowledge of agriculture and handicrafts that transcended the times traveled to the Liang Dynasty. There was no golden finger plug-in, and he could only rely on his own knowledge and deduction ability to improve agricultural tools, increase per-acre yield, build water conservancy and other hard-core farming methods. Step by step, he became a world-famous "Ministry of Industry Wizard". He used solid scientific logic to compete with ancient intrigues in court disputes, imperial examination fraud, and border grain and grass disputes, and embarked on an unprecedented path to the rise of a bureaucrat.
