I Just Passed the Exam, What the Hell Is the Immortal Official System?

Song Li traveled through time and became a newly elected Taoist student in the Zhou Dynasty. At first, he just wanted to live in this world where demons were everywhere, immortals were watching, and the dynasty was full of fierce ministers. But—— What the hell is the Immortal Official System? When you were the agricultural official, you were blessed by the immortal official Shen Nong. Lin Technique->Call Wind and Rain When you were a construction official, you were blessed by the divine official. Pavilions->Dongtian Paradise When you were a Horse Controller, you were blessed by the Divine Horse Immortal Official. Royal Horse->Dragon Subduing ... Many years later. Song Li flew up to Heaven and frowned slightly when he heard that the Immortal Official wanted him to go to the Royal Horse Prison. "Why am I invincible?"
