The Emperor Who Transmigrated Into a Book, and the Eunuch Is Actually a Doubao

After four years of lying flat in college, Lu Yan had successfully returned all his knowledge to his teachers.

And just then, he transmigrated into a novel as an NPC emperor.

Lu Yan clutched his head and wailed. How was iron made again? How did you make concrete? What went into gunpowder?

He'd forgotten! He'd forgotten everything!

And now the eunuch beside him was just staring silently.

"Aren't you going to comfort me?"

The eunuch spoke up. "Haha, I totally get you. I'm completely on your side!"

Lu Yan froze. His expression changed, and he asked cautiously, "Who am I?"

"All right. I'll explain as plainly and directly as possible. You are Lu Yan, the emperor of the Great Zhao Dynasty. You are nineteen years old. Your birth mother is Empress Dowager Su, and your birth father is..."

Lu Yan let out an evil cackle. So my head eunuch is Doubao?
