The Great Yuan's Works Inspector's Notes

Xiao Lanyun, a modern mechanical engineer, unexpectedly transmigrated into the body of a young carpenter in Dadu, the Yuan dynasty, who was constantly bullied. It was an age of rigid class divisions, when artisans were treated as slaves. Fortunately, he awakened the Divine Craftsman System. In his eyes, any tool or machine could be analyzed, optimized, and upgraded. Starting by firing a batch of top-grade charcoal that would revolutionize the age, he improved bellows, transformed ironmaking, and built firearms… With knowledge and skills far beyond his time, Xiao Lanyun rose step by step from the lowest rung of the artisan class to become a Great Yuan Director of Works who shaped the course of the realm amid turbulent times.
