Story:
During the Sui Dynasty, Yang Guang was plotting to seize the position of Crown Prince. Influenced by Yuwen Shu, he exploited an opportunity to persecute individuals with the surname Li, causing many to flee for their lives.
However, Li Jing, undeterred, visited a temple to seek a divination.
There, he audaciously proclaimed his ambition to become emperor, a desire far beyond his actual standing. Regrettably, the divination revealed that he was destined to be merely an influential minister. Consequently, he had to wait for a more opportune moment.
