The Emperor's Secret Tavern Advisor

Stuck in the Tang Dynasty, Zhang Feng inherited a dusty tavern and was told his system would activate in half a year. Six months of boredom later, his only escape is serving bizarre dishes and fielding weird questions from \"Old Li\" – a generous, inquisitive patron who constantly asks about statecraft and politics. Zhang Feng casually dispenses future knowledge, unknowingly guiding the course of the Great Tang. Just as his long-awaited system finally hums to life, \"Old Li\" drops a bombshell: \"It's a showdown, I am Li Shimin!\" Now, Zhang Feng, a common tavern owner, holds the fate of an empire and his own system's first impossible quest in his hands.
