That ancient book, besides Zhang Yi Yuan, was also read by the sinister-looking man.

Under continuous questioning, in order to change his death sentence to life imprisonment, the sinister-looking man told the truth.

Empress Cheng Yangli, after falling ill at the age of 25, has been pursuing the path of ascension.

She believed in the words of a mysterious Taoist.

Using the entire land of Liang Kingdom as the formation base, with forty-nine tomb chambers as the formation points.

Constructing the so-called Ascension Formation.

The final step of the formation is: cremation to transcend the mortal body.

So the true Cheng Yangli had long turned into ashes, dissipating in the mortal world.

I furrowed my brows and shook my head repeatedly.

No, there must be something wrong.

His and Zhang Yi Yuan's explanations are completely contradictory.

There must be something I haven't noticed.

Until later, I remembered the page numbers mentioned in the recorded conversation.

At that time, when the sinister-looking man handed the ancient book to Zhang Yi Yuan, he clearly said:

"Pages 22 to 23 have what you want to know."

But three pages were torn from this ancient book, yet only two page numbers were missing.

In an instant, I realized:

Between pages 22 and 23, there is an additional hidden page.

What is written on this hidden page is the true secret of Cheng Yangli's tomb.

And only Zhang Yi Yuan knows this secret.

But Zhang Yi Yuan hates me.

He refuses to tell me the truth even until death.

On the day before his execution, he said:

"Lin Qing, you will never know how horribly your sister died."
