In the struggle for succession that year, nearly all the nobles and lords supported Zhi Lan. However, they didn't see Zhi Bian coming and he had the last laugh. Since that time, the conflict between the king and the nobles was deeply rooted.
After Zhi Bian ascended to the throne, he immediately carried out a major purge among the nobility, causing them to live in fear and trepidation day and night.
Then he began to massively promote commoner elites, dividing the nobility and the lords, easily smashing the noble class to smithereens.
If this were to continue, despite the nobles' intense hatred in their hearts, they could only hold their nose and kneel before Zhi Bian, singing of conquest, not daring to harbour any second thoughts.
But...
As time passed, year by year, King Zhi Bian soon turned fifty but still had no sons, only one daughter.
Moreover, it was soon confirmed that King Zhi Bian had a hidden ailment and could no longer have any sons, no longer have any descendants.
