The protagonist, Lin Yuan, was the last prince of the Xia Dynasty in his previous life. He had a tolerant and calm personality but missed opportunities due to his indecision. In the end, he was betrayed by his henchmen when the rebels broke through the imperial city, and he committed suicide in hatred. When he was reborn and returned to the age of sixteen, he was still the deposed prince who was shunned by powerful ministers and ostracized by his brothers, but his soul had been tempered into a furnace of iron, blood and strategy. The character becomes soft on the outside and strong on the inside. On the surface, it is as gentle as jade, but in reality, the heart is like a mirror, taking care of everything at every step. The growth arc transforms from "Avenger" to "True Emperor" - at first he just wants to liquidate his enemies in the previous life, but in the process of regaining lost territory and rectifying the imperial court, he gradually takes on the responsibility of revitalizing the dynasty and saving the people from misery. Finally, he sublimates from the obsession with revenge and becomes a generation of holy kings.
