When they first met, Tang Wan sighed, “The fifth young master of the Jiang family is just as the rumors said. He’s celibate, aloof, prideful, and is a man to be revered. Unfortunately, he’s so smart that he no longer has any will to live, which made him sickly, and he’s going to die soon… Later on, the fifth young master brought her into his room. When she came out, everyone stared at her in shock. Why was she crying? …… Later on, it was said that the fifth young master returned after he recovered from his illness, and he brought a girl back.

Its indicators said that its host was indeed mortal. But why did it feel like something was wrong with its host? Dorian lightly chuckled in amusement. He would also like to ask the same question. What exactly was his identity? Well, this would be the biggest mystery of all. But Dorian wasn't in a hurry. Who were his enemies, and who were his allies? Soon, he would find the truth. In the meantime, why not play a little? "Demon! stay back!" "Oooo~~~... I... I want to go back to the underworld where it's safe." "Run for your lives! The demon is here!" …..
