Li Xiaojun thought, could these numbers be referring to the book number?

This way, since the bookshelf had the book number, it would only take three numbers to find a book. The number of the bookshelf, the number of the shelves, and the number of the books.

So, the first number 16 refers to shelf number sixteen?

Li Xiaobing walked to bookshelf # 16. This bookshelf was no different from the other bookshelves; there was a thick layer of dust on it. The second number was 19, which should be the number of the building. In other words, the book indicated by the number was on the 19th floor's bookshelf.

Li Xiaojun brought a ladder from the door. This ladder should be used to retrieve books.

Li Xiaobing took the ladder to the sixteenth floor's bookshelf, climbed the ladder, and climbed to the nineteenth floor.

The third number was 13, which meant that it was the number of the book. The number of the bookshelf was arranged from left to right, so the number of the book should also be arranged from left to right.

Li Xiaojun counted down one by one until he reached the thirteenth book. Li Xiaojun discovered that this book was indeed different from the other surrounding books. The surrounding books were all thick leather, and only this one was a red notebook with a cover.

Li Xiaojun took down the notebook from the shelf. As he picked up the notebook, a button that had been pressed by the book popped up.

With a clang, Li Xiaojun turned around and saw that the bookshelf behind him had actually opened a door.

This button was the mechanism of the secret door!

Li Xiao Jun revealed a complacent smile. She placed the notebook in her pocket, climbed down the ladder, and put it back where it used to be. He walked to the hidden door and looked inside. There, he saw a pitch black passageway that led to who knows where.

It might be dangerous, but at this moment, Li Xiaojun could no longer suppress his curiosity and walked through the secret door.

The moment he stepped through the secret door, Li Xiaojun found a black knob on the wall. Li Xiaojun turned the knob, and the door closed behind him. There was no light source in the tunnel, and everything suddenly became pitch black.

This button was used to close the hidden door after entering the tunnel.

Li Xiaojun took out his mobile phone, turned on the flashlight, and walked forward using the light of his flashlight.

This passage was just like the one from before, the surrounding walls were made of concrete.

Li Xiaojun thought that there was a maze of crisscrossing tunnels, but in reality, there was only a single path leading to a single place.

Li Xiaobing walked forward while using the light. He didn't know who had built this tunnel, but he had heard that every Wealthy Class family would build an escape route inside their house for emergency use.

This passage was much longer than he had expected. Although he didn't know where he had reached after walking for a while, he was certain that he had already left the Jiang residence.

After walking for an unknown amount of time for more than ten minutes, Li Xiaojun finally reached the end. At the end was a hidden hole in the wall. Li Xiaoyan crawled out of the hole in the wall. There were several layers of tall grass outside, which perfectly concealed the hole. No matter what, the secret of this hole could not be discovered from the outside.

Li Xiaojun came out from the hole and stood under the sunlight. For a moment, he felt like he had seen the light of day again. When he looked around, he saw that he was by a river. The river flowed with clear water. Li Xiaobing looked left and right. This was a piece of barren land, and the nearest road was at least a few hundred meters away. Behind him was the river, and there was no other way.

Li Xiaojun walked over to the river and looked at his reflection in it. This river was the Mausoleum of Books.

Li Xiao Jun thought of Jiang Wan Ling's uncle, Jiang Hao's mysterious brother who committed suicide. His body was probably found nearby.

Li Xiao Jun was one hundred percent sure that Jiang Hao's brother had escaped the Jiang Residence through this secret passage, arrived at this place, and then committed suicide.

However, this only explained how Jiang Hao's brother escaped from the Jiang Residence, but could not explain why Jiang Hao fled to the outside to commit suicide.

Li Xiaojun walked leisurely along the river towards the main road. He was thinking at the same time.

Jiang Hao's brother had been deprived of all his rights and position because he had colluded with the Li Family to murder his brother. If Jiang Hao did not do anything to him, why did he commit suicide?

Perhaps … He didn't actually commit suicide?

Li Xiaojun shook his head with a bitter smile, and quickly dismissed the idea from his mind. After all, the person who died was the younger brother of the Jiang Clan's clan head. If he was really killed, even if the police couldn't solve the case, how could the Jiang Clan not be able to find out the truth? For a great clan like the Jiang Clan, their network of connections was extremely developed. To the Jiang Clan, no one would be able to escape their pursuit.

Since even Jiang Hao admitted that his little brother committed suicide, there probably wouldn't be any accident.

What if it was Jiang Hao herself?

Li Xiao Jun's body trembled, and she couldn't help but stop her steps.

If the one who did this was Jiang Hao, then he definitely had to hide the truth. It wouldn't be weird for him to claim that he committed suicide.

Li Xiaojun suddenly remembered the notebook in his bosom. He took out the notebook from his bosom and opened the book under the sunlight.

This notebook must be quite old and the paper is turning yellow.

Li Xiaobing opened it and saw that it was a handwritten diary.

"June 16th, sunny. "Everything is going smoothly. As long as the time is up …"

Although he did not sign his name, but after reading a few pages, Li Xiao Jun understood that this was Jiang Hao's little brother's diary.

The first few pages of the diary described his plans to contact the Li family. But the diary stopped halfway through, it was clear that Jiang Hao had found out about the plan and was not in the mood to keep a diary anymore after the east window incident.

Li Xiaojun flipped to the last few pages, and suddenly found the words on the last few pages.
