Jiang Shiyu did not think about all this, and pointed to the big doors of the library: "You have a way, when I walked in just now, it was as though I was blocked by something, and cannot go in."

Cheng Yu continued: "Moreover, this is only the first door. If you want to enter the small room, there must be at least two other doors blocking you."

Jiang Shiyu laughed in his heart. He didn't point out that there was something wrong with his words. Cheng Yu looked really close to him, but if he was unwilling, even kowtowing to him after begging him a thousand times wouldn't do.

Cheng Yu nodded, "Close your eyes."

Jiang Shiyu: "I can't look?"

Cheng Yu nodded slightly.

Jiang Shiyu obediently closed her eyes. Although she was curious as to how Cheng Yu broke the formation, since she didn't want to see it, she naturally couldn't see it.

Jiang Shiyu felt like she had only closed her eyes for a short while, when she heard Cheng Yu's voice.

Jiang Shiyu opened her eyes and tried taking a step forward. Then, she took another step and went in. The transparent door was indeed broken.

Jiang Shiyu was ecstatic, she immediately rushed in, and thought about the two doors inside, she was afraid that none of them could be broken, and stood there waiting for Cheng Yu.

Jiang Shiyu judged that Cheng Yu was not anxious at all when it came to doing things, he was also walking in, and was not the least bit anxious, so Jiang Shiyu quickly urged him: "Hurry."

Cheng Yu looked at her, "You don't have to wait for me, go in first."

Jiang Shiyu felt that Cheng Yu did this on purpose.

He just stood there, waiting for him to arrive. Although Cheng Yu was not running, but he was tall, with long legs, he caught up to Jiang Shiyu within a few steps. The two of them walked in side by side.

This was the first time Jiang Shiyu came to the secondary building, but she did not know what was happening inside. There was a long corridor, with a few beautiful landscape paintings hanging on both sides of it, it was extremely dark.

Cheng Yu walked over first.

The wooden staircase looked very old, and the creaking sounds of people stepping on it sounded as if it would fall apart at any moment. However, it still existed here for so many years.

Jiang Shiyu and Cheng Yu stepped forward together. Other than sound, nothing else happened.

Jiang Shiyu was a little curious, "We just passed by a long corridor, and there are some rooms on both sides.

Cheng Yu: "They are also books, and are all very precious."

Jiang Shiyu took a deep breath, "We just passed by 8 rooms, the sides of the rooms are symmetrical, there are 16 of them, and every room is filled with books, and inside that are …."

"There aren't that many. No need to be surprised. Although the ones below are also very precious, they're still nothing compared to those on the second floor." Cheng Yu said lightly, "We have reached the second floor, this is the second door."

The two of them had already reached the end of the wooden staircase and there was a wooden door above them. On it was a drawing of the Nine Heavens Academy's forehead, Cheng Yu held onto the handle and pushed it in.

Jiang Shiyu held her breath.

"You can't open it like this." Cheng Yu pushed but he did not push his away as he explained to his in a light tone.

Jiang Shiyu took a deep breath, "..."

Cheng Yu teased Jiang Shiyu a little, "Do you know the symbol on the door?"

Jiang Shiyu nodded, "It's the school mark of Nine Heavens Academy."

Cheng Yu nodded, "When Nine Heavens Academy first established this institution, it was not used for the sake of the academy. It was only for one thing."

Jiang Shiyu: "You can talk about this later, hurry up and open the door!"

Cheng Yu turned around and said, "If you don't listen, you will regret it in the future."

Jiang Shiyu's eyes and heart were currently filled with the desire to quickly move the book. All of these things could be discussed later, but once she thought about the fact that the Nine Heavens Academy was about to be destroyed, she said after thinking for a moment: "Open the door, and tell me while you're at it."

Cheng Yu said coldly, "If one chance is lost, then it's gone."

Jiang Shiyu touched her nose awkwardly, and did not bring up the matter anymore.

Cheng Yu said again: "Close your eyes."

After the first time, Jiang Shiyu immediately closed her eyes.

When she heard the creaking sounds of the wooden door, she opened her eyes. Cheng Yu had already entered, and she followed him in.

When he reached the second floor, he found that the layout was a little different. There were two rows of tables and chairs arranged neatly. The tables and chairs were very smooth.

"Pata ~ ~ ~"

The overhead light was turned on.

Jiang Shiyu was shocked, "Cheng Yu, quickly turn off the lights, we will be discovered."

Cheng Yu chuckled, "Look around first."

Jiang Shiyu only knew that lighting a light would attract people, after hearing Cheng Yu's words, he looked around.

"Here... There are no windows, only walls on all four sides, completely sealed off! " Jiang Shiyu was shocked, "Where is this?"

Cheng Yu walked in front of the innermost door, "Can't tell? The books in the secondary building are not allowed to be borrowed. You can only read them from inside. "

"However, it was sealed off from all four sides, and not a single ray of light leaked in. This is too bad."

Cheng Yu nodded his head: "Usually that's the case, but the books on the second floor are very precious. Some of them have existed for many years and cannot be exposed to the light, otherwise, they would slowly break down."

Jiang Shiyu understood, "So it's like that."

Cheng Yu stood in front of the door and waved, "All of the solitaries are here. "About a small room."

Jiang Shiyu still had not gone in, but an excited feeling had actually risen in her heart.

Cheng Yu looked for a moment, "Eh, someone has been here before, the pattern on it has changed."

Jiang Shiyu didn't understand, so she said: "You can read the books in this orphanage, but in order to preserve them better, only three people are allowed to enter and exit this room every day. Look at this design. If no one enters, it will be a proof of achievement. After the first one enters, it will become the sun. The second person to enter became the moon and the third person to enter became the stars. Once you become a star, no one will be able to open this door. "

"Look at the pattern on the door."

This place was the innermost area, even if there was light, this place would still be dark. Jiang Shiyu moved her face closer to look and saw that it was a circular sun that was emitting light. However, the light seemed to be drawn on it, not at all bright.

Jiang Shiyu said: "Someone has already entered."

Cheng Yu nodded, "Yes, moreover, this person should still be inside."
