Su Xiao opened the huge scroll. It was really a catalog. The crystallization system was more complicated than he thought. He flipped through it for a while and found the two parts "Energy Crystallization" and "Soul and Crystallization". He was very interested in these two aspects.

interest.

"I want both parts."

Su Xiao clicked on the record on the scroll. Seeing this, the old dean smiled and shook his head and said:

"This is a secret of our Dragon Academy. They are all stored on the top floor of the big library. Even if the tutors of our academy want to borrow them, they must make a reciprocal contribution."

"I exchange the records in the second half of the Book of the Sun."

"Young man, your generosity is gratifying."

The old dean closed the big scroll. What secrets were not told? Once the bid was high enough, they were immediately told.

The old dean stood up. Seeing this, Su Xiao also joined him. After leaving the study, tutor Leopold and apprentice Nita were waiting outside.

Seeing the old dean's expression, Tutor Leopold immediately changed his attitude. He walked side by side with Su Xiao, stuffed a small bottle containing blue liquid into Su Xiao's hand, and said: "There will be opportunities in the future.

If so, we will cooperate again.”

Tutor Leopold smiled and didn't mention anything about what happened before, which meant that this was the end of the story.

Along the way, Tutor Leopold began to talk about the history of Dragon Academy and how many outstanding students it has produced.

When the group arrived at the door of the big library, they had to go through several levels of interrogation before entering, even if the old dean personally led them.

The large library has four floors in total. The first three floors are connected and have a somewhat responsible layout, while the fourth floor is completely independent.

Half an hour later, the group arrived at the metal door on the fourth floor. The old dean took out the key and opened the door himself. In the entire Dragon Academy, only the old dean had the key to the fourth floor of the big library.

"Baiye, the amount of knowledge stored on the fourth floor of the big library will definitely exceed your imagination. Many people have tried to steal the precious books inside, but no one has succeeded."

As Teacher Leopold spoke, the metal door on the fourth floor of the large library slowly opened.

"This is the foundation of our Dragon Academy."

Instructor Leopold put his hands behind his back and raised his chin slightly. When he saw the scene in front of him clearly, he almost suffered a brain congestion.

On the fourth floor of the huge library, not to mention ancient books, even the bookshelves were gone, with only three or five pieces of paper left on the floor.
