It was a common theme in stories that one could only rise above others through enduring hardships.
The Third Prince, who had been poisoned from a young age and then cultivated an unparalleled mystical technique in the face of adversity, followed the typical trajectory of many male protagonists in books.
In the book's plot, the Third Prince had been hunted down by his Eighth Imperial Uncle, who had already ascended the throne, and they were on the brink of a deadly confrontation. Their only recourse was for the Third Prince to dethrone the Eighth Imperial Uncle if he wished to survive. Being the male lead, he was fated to become the emperor.
Now, the Third Prince was being relentlessly pursued by the Crown Prince. If he didn't succeed on his first attempt, there would inevitably be subsequent attempts. The Crown Prince and the Third Prince were locked in a life-or-death struggle, and the Third Prince had to eliminate the Crown Prince to ensure his own survival.
