"Li Chunfeng": the hard-core legend of the first "slash youth" in the Tang Dynasty
He was the most awesome "slash youth" in the Tang Dynasty: astronomer/mathematician/Taoist priest/prophet/meteorologist. It can not only measure the stars with the armillary sphere, but also predict millennia with the "Tuibei Diagram". It can also grade the wind and annotate mathematics textbooks - and by the way, it can help the emperor avoid lightning.
This book will help you unlock the hard-core truth behind "divine calculation": there is no magic, only hard-core observation; there is no superstition, it is all logical deduction. See how Li Chunfeng used science to refute false prophecies, used wisdom to protect Chang'an fireworks, and spent his life interpreting - the real divine calculation is to understand God's temper and give the people a stable tomorrow.
