Name: Wang Bing Long
Status: 1st life (Died after being run over by truck-kun) / 2nd life (Alive)
Bio: Wang Bing Long is the protagonist of the "Transmigrated into The Body of a Chinese Prince even though I'm Japanese." In his previous life, Wang Bing Long was just an ordinary Japanese High School student who lived in an apartment complex located in Tokyo City's China Town. He was killed via being hit by truck-kun after saving a female disciple of Confucianism from being hit instead. Instead of passing through the pearly gates, the soul of this Japanese teen would transmigrate into the body of the recently deceased prince Wang Bing Long of the Chinese-like nation known as the Qin Empire (Other than the name there is no relation to the Qin Empire in Chinese history). The new "Wang Bing Long" would then do his best to ensure that he could live a slow peaceful life mooching off the royal treasury, but his actions had the unintended consequences of him rising through the ranks of the Qin Empire eventually deposing the previous crown prince to become the crown prince himself.
Inspired by: Wang Bing Long is inspired by 2 fictional characters and 1 character type. The first is Tanya Degurechaff from Youjo Senki, the second is Suzuki Satoru or Ainz-sama from Overlord in regards to his actual personality, and the last are the cold male leads of female protag cultivation novels like Jun Wu Yao from "Genius Doctor: Black Belly.
Name: Ye Fei
Status: 1st Life (Died from falling from great heights) / 2nd Life (Alive)
Bio: Ye Fei is the female lead of the story who in her previous life (also "totally coincidentally named" Ye Fei) was the young lady of the Ye clan who specialized in pharmaceuticals made from eastern and western styles of medicine. She was just about to succeed in becoming the next head of the clan when she was suddenly betrayed by her half-sister who she until that moment thought could be trusted with her life. Ye Fei's half-sister and her followers pursued her until she was surrounded demanding that Ye Fei hand over the clan's ancestral artifact and the key to their power as a pharmaceutical base… the mystical Nine-headed Azure Dragon Ring. Preferring death instead of handing it over, Ye Fei jumped off the tall cliff. She suddenly blacked out mid-fall as the ring started to glow before waking up in the body of a bratty young wastrel missus of one of the Qin Empire's most prestigious military families.
Inspired by: Female leads like Gu Ruoyun from "Evil Emperor's Wild Consort" or Ling Lan from "It's Not Easy to Be a Man After Travelling to the Future"
Name: Ye Wei
Bio 1st Life (Died from a spear through the heart)
Ye Wei is the child of the Great Qin Empire's old war god Ye Fang and is a member of the Ye clan, who have several generations of military service. He wanted to rise to the ranks and become a great general like his father and ancestors but never made it past the rank of being a 100-man commander due to a combination of his arrogance founded in pride and hot-bloodedness among a few other factors. Even so, he was still loyal to the nation and far from being stupid as he saw his Qin Empire slowly torn apart by corrupted civil and military officials while being completely powerless to stop them. He would die in the Qin Empire's (ultimately failing) last stand. The next thing he knew…. He found himself back in his room at the Ye family home as a young boy. Grateful of heaven's mercy, Ye Wei swore to change the fate of his homeland. He would start by becoming a follower of Prince Wang Bing Long... a member of royalty Yei Wei found to be an anomaly in his new life because at the same point of time in his previous life... Prince Wang Bing Long had long been deceased.
Inspired by: A combination of Wang Chong from "Records of the Human Emperor" and Roan from "I am the Monarch"
Wang Cao
Bio: Wang Cao is the father of the novel protagonist and 8th prince Wang Bing Long and is the 18th emperor of the powerful Qin Empire. Several years before the start of the novel, Wang Cao noticed that his father the 17th emperor of Qin (though not the talented of rulers) was slowly becoming corrupt and lusting after riches. Before the 17th emperor took the Qin Empire past the point of no return, Wang Cao gathered like-minded supporters from the civil and military officials to launch a coup d'é·tat and remove his father from power and ended it by personally killing his father with his own two hands. Wang Cao has spent the following years working to bring back stability to the Qin Empire. He had wanted to marry out of love, but tossed that thought aside for the sake of Qin's stability by taking in a few concubines from his supporters. Still.... there was one woman he truly loved, and it's a shame she died before she could both become his empress and see their son grow
Eunuch Bai
Bio: Eunuch Bai was a teenaged morally-upright eunuch assigned to Wang Cao as his personal assistant back when he was just a prince of Qin rather than the emperor. At first, he didn't think much of the child prince due to the budding corruption of the 17th emperor, but would later swear undying loyalty after seeing Wang Cao grow up and maintain his sense of honor and morality despite the actions of his father and his siblings and would assist in Wang Cao's plot to overthrow his father. In fact, Eunuch Bai would say that the emperor's greatest trait is him being fully objectively aware of everything he lacks and what it is he must do to fill in the gaps.
Eunuch Yunfei
Bio: If Eunuch Bai is known as the right hand of the emperor then Eunuch Yunfei is known as his left. His appearance and tone of voice perfectly match the epitome that is being a "Shady son of a b****", and to no surprise to those in power the emperor trusts him personally to dish out the punishment to sinning officials and handle matters in the dark the emperor cannot entrust to his shadow guards nor the Qin's spymaster. What does surprise those in power, however, is the fact that he remains implicitly loyal to the emperor despite his demeanor suggesting he'd be anything but.
