The Book Immortal saw the answer, yet finding it only deepened his confusion.
If a question was without an answer, like involving a taboo, he would sense it, knowing that he ventured into forbidden territory and would thus desist.
But he merely changed the way he phrased the question, and the Heavenly Book provided an answer.
In this answer, Lin Yun was already a dead man.
An identity not to be spoken of, the Book Immortal knew clearly in his heart.
Lin Yu was the White Tiger, different from those who received the Power of the Four Kings. Others received Divine Power, but Lin Yu was the White Tiger incarnate, whose true name must not be uttered, yet the Book Immortal knew who it was.
And when Lin Yu had previously interacted with the Heavenly Book, it had also revealed her destiny. Even as the White Tiger incarnate, she couldn't escape the prophecy. Who, then, was Lin Yun to be sacred?
