A modern grassroots civil servant has the soul of a poor scholar in the Tang Dynasty. He has no gunpowder glass, no gold and iron horses, only an original intention to do things for the people and a brain full of "stupid ways". He started by rescuing a military horse, worked his way up the imperial examination step by step, struggled through the quagmire of officialdom, and finally used the simplest principles to live his life as the most extraordinary person of this era.
