Why was Cao Pi, who was inferior to Cao Zhi in literature and inferior to Cao Zhang in martial arts, able to seize the throne in one fell swoop? Why would Cao Cao, who values force most, give up his throne to the "inconspicuous" Cao Pi? Why did Jia Xu, "the most poisonous person in the world", support Cao Pi in the end? There are too many mysteries in all of this, and this book "Han Cicada" will show a hearty battle of intelligence and thinking. And uncover one mystery after another.
