Hua Cheng is the male lead of the novel. As one of the Four Great Calamities, Hua Cheng is known as the richest and most dangerous of the three Devastation class Demons. One learns to fear the silver butterflies and blood rains for they are the heralds of his presence. He is charismatic and intelligent, with a nonchalant attitude. He cares little for others and mostly acts in his own best interest. However, to Xie Lian he is very gentle, treating him with the utmost care and respect and offering him anything he desires. Despite being a ghost king, he is not outright evil, seemingly neutral as he neither undertakes altruistic actions nor engages in evil or barbaric acts. He seems to have a love of collecting rare treasures, having a large collection of antiques and priceless artifacts and weapons, some of which are thousands of years old. Ironically, he treats them rather poorly. He does not care when they are destroyed and has been shown to abuse or misuse them himself on occasion. He is confident in his abilities, though rightfully so as he is one of the most powerful beings. Despite this, he does have a more vulnerable side. (Source: Heaven Official's Blessing Wiki)
