"Can you speak now? But I have to say it first, if the source of what you say is not verifiable, then this question does not count. ”

Cen Shan just wants to hold on to this issue, as long as Su Caiyin can't tell the exact source, then he has nothing to be ashamed of.

In fact, he was very sure of his judgment, this question was simply made out of nothing, maybe the names of those two herbs were made up by Su Caiyin himself.

"There is a relevant record in the second volume of the book "Secret Record Examination".

Suddenly, a voice came, the voice was old and calm, and answered Cen Shan for Su Caiyin.

Su Caiyin was slightly surprised and looked somewhere.

Yu Lao was wearing an inconspicuous robe, sitting there like an invisible person, if he hadn't spoken out, I'm afraid few people would have noticed him.

""The Secret Record"? Why haven't I seen this book, it's a wild history? Cen Shan's heart jumped and asked in a cold voice.

"Noshi? Hehe. ”

Yu Lao laughed lightly and shook his head, "You don't know, it's because there are too many books, and you can't see every one, but if you don't see it, it doesn't mean that it doesn't exist." ”

Cen Shan's face was even worse, and he was about to continue asking, but he saw Yu Lao waving his hand somewhere.

There were too many people everywhere he looked, and Cen Shan didn't know who he was waving to, and he didn't see anything when he went to look.

"Don't worry, you'll know when the book comes in a moment."

As he spoke, Yu Lao closed his eyes slightly.

There were whispers in the field, and the students looked at Yu Lao for a while, and Cen Shan for a while, and they didn't know who to believe, but they even said the title of the book, so there shouldn't be anything wrong, right?

Su Caiyin's gaze seemed to be retracted from Yu Lao with deep meaning, and she couldn't help but think that this Yu Lao was definitely not a simple character.

The field was quiet for a while, waiting for someone to bring the book, and it didn't take long for a white figure to walk in front of Cen Shan's Su Caiyin.

This is a gentle and elegant man, as clean as a mountain spring, he behaves modestly, and when he walked over, he first saluted Cen Shan, and then smiled at Su Caiyin.

"This is the "Secret Record", please check it out."

As he spoke, he handed over a very shabby book in his hand.

Su Caiyin looked at him, and he smiled back.

This was the unknown man in the Scripture Pavilion of the Dan Academy, it turned out that he was in the crowd before, and she didn't even notice it.

As soon as Cen Shan saw the book, he reached out and grabbed it, and seeing his movements, the man in white couldn't help frowning, as if he was a little dissatisfied with this rude action that hurt the book.

The sound of flipping the book sounded, Cen Shan's eyes were firmly fixed on the book, and everyone else was staring at his movements, wanting to see some clues from it.

Finally, his movements stopped, and gradually, his face turned a little pale.

"How? Can Dean Cen see clearly? ”

Su Caiyin said softly, "The reason why the medicine was changed was because the effect of the former was ineffective, so after two years of testing, Master Menghui finally found a more suitable medicinal material, so he replaced it, and not long after he changed the pill, Master Menghui fell off the cliff because he went to collect medicine himself, thus losing his life." ”

Su Caiyin was not so much for Cen Shan as for the others present, after all, not everyone could see this book.
