Wumeng alchemy room.

Ye Yu stands with his hand in his hand, looking at Qingxuan with a light face.

"Taoist Qingxuan, I didn't mean to humiliate you."

Ye Yu's voice is bland, "I'm just stating a fact!"

After hearing what ye Yu said, Qingxuan's face, which was already ugly, turned darker.

What a bully!

Qingxuan wants to cry at the moment.

"Ye Yu! Is the poor way so ignorant in your eyes? "

Ye Yu shook his head and said softly, "it's not ignorance, but limited vision and too little information!"

"How could it be!"

Qingxuan does not hesitate to refute Ye Yu.

Because Qingxuan has this foundation, he is proud!

"Ye Yu, how many ancient books about alchemy do you have in the Taoist League?"

Didn't wait for Ye Yu to answer, green Xuan said proudly, "one hundred and eight thousand volumes!"

"Have you seen it all?" Ye Yu asked aloud.

"What?" Qingxuan was stunned for a moment, but didn't seem to hear Qingyu's inquiry.

Ye Yu looked at Qingxuan calmly and said softly, "have you seen all the ancient alchemy books collected in the Taoist League?"

"·"

Qingxuan was silent for a moment, and then said faintly, "I haven't seen all of them, but!"

"the essence of this is poor, but it has all been studied."

"the essence?" Ye Yu sneer. "It's the essence of Tao Chang himself."

"Eighteen thousand?" Ye Yu laughs, "let's not say how many of them are repeated."

"Let's say that books like exaggeration, mystification and conjecture account for most of them!"

Qingxuan is silent.

Because ye Yu is right!

In ancient times, alchemists paid attention to taking their masters with their disciples.

>

Master chooses disciples to teach them.

There is a saying that goes like this.

Master leads in, practice is personal!

The meaning of this sentence is to encourage the self breakthrough of apprentices.

But at the same time, it has another meaning.

That is to say, master's skills are not all handed down to his disciples!

What's more, the master did this to his disciples.

So when he wrote books and biographies, would he write all the things he pressed on the bottom of the box and let people browse and watch them?

No way!

So say.

After thousands of years, most of the alchemy books that can be widely spread are basic things!

Even if it's something profound, it's just fur!

The real profound knowledge will not be written on paper!

So Ye Yu is determined that most of the ancient alchemy books collected by the Taoist league are floating on the surface.

Otherwise, the alchemy level of daomeng will not be so bad!

green Xuan silent for a moment, looked up and still stubbornly said, "even so, in the collection of Dao Meng, part of it is the real essence!"

Ye Yu nodded and agreed, "the Taoist is right. But what about that? "

"Can the Taoist priest distinguish these really useful things from the vast number of ancient books?"

"Why not?" Qingxuan is very dissatisfied with Ye Yu's skeptical tone.

"Good!" "I know that there is an ancient book of alchemy, which is very popular. There must be a collection in the Taoist League."

"In this ancient book, it is clearly recorded why the Dan Qi has risen, but the Dan medicine has not been completed!"

"How is it possible? Why hasn't this ancient book been read? " Qingxuan looks at Ye Yu with suspicious eyes, "what is this ancient book you said?"

The smile in Ye Yu's eyes flashed, then he said aloud, "this ancient book is... Journey to the West!"
