“Any who don the title of 'king' or anything of the sort in my presence is nothing more than an ignorant fool. This is my land and I shall be reclaiming it soon. I am Cacophony, the Vampire Empress!”As those words left her lips, every cell in my body reacted. It was unreal—no, it was otherworldly. Her beauty, her power, and her overwhelming arrogance. It might've been then that I realized that my normal life had ended.How did it come to this?Ah, it was curiosity. Yes, a deathly curiosity brought me to that graveyard that day.It was there that I stumbled upon her coffin. I had absolutely no clue what I was doing then, and even now I have no idea what possessed me to touch it—that single moment changed the course of history for the entire world. I found myself delving into a completely unknown world.Should I regret it? Maybe. But the truth is, I don't.Exploring the world’s hidden secrets, forging unexpected bonds, and living alongside the revived empress—it’s exciting.“Even if it's wrong, I think I'm going to enjoy every moment of it.”

Ye Zhen, a female Ph.D. in the Department of Mathematics of Huada University, changed her career to enter the entertainment industry in order to investigate the death of her birth father, Film Emperor Ye Yi. During her interview, she accidentally made CEO Rong Cheng Jue lose face in public. Yet Rong Cheng Jue, unlike what was to be expected, didn’t take old grudges into account and let Ye Zhen join his company. When everyone thought Ye Zhen would become Rong Cheng Jue’s personal secretary, she actually joined the entertainment department. After several twists and turns, Ye Zhen became an errand reporter for Rongcheng Entertainment’s “Treasures of Great Tang”.

Her colleagues’ bullying towards her, the pressure of changing career, and the many obstacles in her investigation all left her confused. Under Rong Cheng Jue’s silent guardianship, she didn’t forget her original purpose, overcame every obstacle, and eventually became an ace producer.

Ye Zhen and Rong Cheng Jue shared a common belief : no matter how bleak the hope is, how thorny and dark is the road ahead, they had only one thought in their hearts: to uncover the truth, and therefore bring peace to the soul of the Film Emperor Ye Yi.
