The Yong Dynasty was established for more than a hundred years and after three emperors, the fourth emperor Xiao Yan became dim-witted in his later years and was addicted to elixirs. He allowed his wife Wei and his powerful minister Lin to fight. The prince's fight for the right to inherit the throne became more and more fierce.

The dynasty seemed prosperous, but in fact it was troubled by internal and external troubles.
