The fourth floor of the stone pagoda is still a room for living, with the same layout as the third floor, Song Rui searched carefully, but still did not find it.

The fifth floor is slightly different, it is still a living room, but the style is slightly softer, and the arrangement is slightly more, with a few shelves on one side of the wall, and a row of cabinets on the other wall, some high and some low, staggered.

Although there are not many feminine colors and decorations in the room, Song Rui still feels that this should be a woman's room, which is groundless but accurate.

There is not much dust in the room, just like the owner has just left, it seems that the tables and chairs are all with the residual warmth of the owner, and even if a cup of hot coffee appears on the table, there is no sense of disobedience.

Song Rui sighed, I don't know if it was because of the helplessness of searching for a long time without results, or because of the loneliness of this person going to the empty building.

Zebra stood at the top of the stairs, with no intention of coming in, he leaned on the handrail of the stairs and watched Song Rui busy in the room.

Song Rui searched from the shelves closest to him, and there was nothing on the shelves, but because the shelves themselves were wooden, once something was placed on it for more than a year, it would leave permanent traces. Song Rui speculated based on the traces of each lattice that there were a lot of things placed on the shelf itself, and the items were very miscellaneous, so it was difficult to guess what items were placed through the traces, but at least it was certainly not a book.

After recording every remaining trace in detail, Song Rui's eyes turned to the table next to him, and there were also traces of items placed on the table, which should be a book shelf, an inkwell, and a pen holder. There had been at least three books on the shelves, all of them thick, at least a thousand pages, with a slightly wide cover and untidy edges...... It is made of sheepskin or cowhide.

The wall above the desk is inlaid with a lit stone, which is positioned in a way and at a reasonable angle to cast a soft white light on the desk.

The table has no drawers, and a chair is placed in front of it, both of which can be seen to be handmade, simple in shape, polished, but not carved and hollowed.

The bed on the other side was empty, and I searched up and down carefully, but found nothing.

On the wall opposite the desk is a row of cabinets, which seem to be wardrobes, Song Rui opened each cabinet door, searched carefully up and down, left and right, and finally found it in the gap under the cabinet.

"Hah!" It's a hair!

Song Rui lay on the ground, carefully removed the cabinets on both sides, pinched the hair in his hand, kept it in a transparent sealed small bag, and put it away closely. It suddenly occurred to me that the act of collecting other people's hair closely, as if only boyfriends and girlfriends would do this?

The hair is blonde, long and soft, with two curved arcs when pinched, and the tail is playfully curled upwards for a smooth and shiny finish.

Song Rui once heard that people with soft hair are soft-hearted people, gentle and slender, and have keen feelings.

That's not the point, though! There is no doubt that this hair is human hair! And it's quite possible that it's a woman's hair! Although men also have long hair, such as Sani, Song Rui prefers to believe that it is a woman's hair.

Song Rui touched his left arm, a piece of the forearm that was gnawed off by Nitro has not grown yet, this place is indeed the remains of Nitro! But there are signs that humans have survived here, and this ...... This...... What's going on?!

And, judging from the decoration and layout of this room, this person is still living comfortably here?

Song Rui felt that his brain was knotted again, because this was completely unscientific! Nitro keeps humans in captivity? Humans breed Nitro in captivity? Mutual captivity? Judging from the three situations he considered, the brain circuits of this thing have been wound around in a fancy way!

But, again, this is completely unscientific! What kind of creature is Nitro? Unparalleled appetite, super combat power, a fiery temper at the slightest bit, and, most importantly, they also cook humans! Material! Reason! Person! Kind!

It can be said that Nitro and humans are two creatures that are absolutely opposites, and if there is anything to do with them, it is probably the relationship between diners and ingredients...... Of course, this kind of food is free-range, and from time to time it is teased by diners......

Therefore, captivity or anything should be completely non-existent, and therefore, it is completely unreasonable for a human hair to appear here!

Zebra couldn't figure out what was going on, so the two of them went up to the sixth floor in a full stomach.

The sixth floor is not an independent space, Song Rui visually predicted, it should be the sixth, seventh and eighth floors of the tower in the middle of the opening, connected into one.

After coming up from the staircase, there is a passage that leads to the center of the sixth floor. With the center as the center of the circle, extending upwards in a stepped shape, is a circle of bookshelves, the bookshelves are arranged on eight sides, just in line with the shape of the tower, there is a narrow passage in the middle of each two sides, and the passage where Zebra and Song Rui enter is one of them.

The moment he saw the six-story layout, Song Rui felt a burst of excitement in his heart, and then a burst of disappointment...... Excitedly, it looks like a place to store books, but disappointed, the shelves here are empty!

The bookshelf is also wooden, the style is as simple and simple as ever, and the small lattice of each bookshelf is inlaid with this pearl, standing in the center of the sixth floor and looking up, there is an illusion of being in the sea of stars.

Song Rui glanced at the bookshelves hastily and confirmed that they were basically empty, so he set his eyes on the center of the sixth floor, where there was the only book here.

The book is made of parchment, the craftsmanship is meticulous, the surface is smooth, the feel is soft, but the binding is slightly rough, the text on it is unconventional, the ink is clear, and the color is full. But...... The Babel language is still used, that is...... I don't understand it for the time being!

Song Rui felt that his exploration along the way was too breathless! Either there are no clues, or there are no direct clues! It feels like an open-book exam, but all the questions are comprehension questions, and the answers are either not found or not used!

"Okay...... You've got a kind! Song Rui didn't know who he was angry with, so he put the book away indignantly, and made up his mind to study the language of Babel well! And then use this language to write a million spit text to take revenge on society!

He thought so, but the movements of his hands were very careful, he put the parchment book in the middle of the backpack, pressed it with his hand, and still felt uneasy, and turned the backpack behind him to the side and hugged it in front of him.

This is very precious information, if he accidentally loses it, Song Rui feels that he should swallow feces and commit suicide.

At a very fast speed, they checked the space of six, seven and eight floors to confirm that there was no omission, and the two of them went up to the ninth floor, which was the last floor of the stone tower.
