In the confinement tower, a figure shuttled through all the floors, so fast that it blurred the vision, and it was almost impossible to tell if it was a human shadow or not.

At this moment, it is obvious that the dust on each staircase is slightly rolled up, although it is very light, but in this silent night, along with the lit candlelight, it is the only movement.

Yun Yu ran mechanically, although he had clearly felt his rapid panting, but it seemed that a magic force appeared, making him want to stop, as if the legendary madness could not be stopped.

"Bang!"

A loud bang, followed by a loud bang, Yun Yu suddenly paused and threw himself backwards from a few steps up.

He took a quick deep breath, looked at the darkness in front of him, and couldn't see his five fingers, just asked about the faint smell of blood.

Yun Yu wiped his forehead with his palm, and he felt the viscosity of the blood, yes...... Did you hit it?

When he came back to his senses, Yun Yu realized that he was not on the thirteenth floor where the oil lamp was lit at all, but the pitch-black fourteenth floor, and it was the passage from the fourteenth floor to the fifteenth floor.

Yun Yu couldn't help but feel a chill, the last time he was here, he was beaten back to the thirteenth floor by Xia Yuan in a few moves, and that sense of terror is still there.

After adjusting his breathing, Yun Yu slowly stood up, and a strong force in his brain prompted his legs to walk towards the fifteenth layer of the iron door.

Now, Xia Yuan is no longer in the confinement tower, thinking of this, those trembling legs slowly regained their calm, took out the sunstone from the jade belt, controlled it with spiritual power, and in an instant, it lit up.

The windows on the fourteenth floor of the Confinement Tower are windowless. Therefore, the light was too strong to inevitably attract the attention of the outside, and Yun Yu quickly suppressed the aura and adjusted the light of the sunstone to the intensity that was not enough to transmit outside the tower.

Cautiously, Yun Yu walked to the locked iron door again after many days, and raised the sunstone to the side of his face, Yun Yu looked at the fifteenth floor.

The fifteenth floor is the spire, and the space is much smaller than the other floors, but Yun Yu has seen the layout in this room before, and there is no change. There were still tables, chairs and beds as before, but moving his eyes to the bookshelf next to the bed, Yun Yu couldn't help but be stunned, this ...... Someone has been here!

The last time I visited, the bookshelf was covered in dust. And this time, although the dust does not abate. But the door panel at the lattice on the cabinet was different from before.

Previously, each compartment was closed with a door panel. And now there is clearly a door panel that is hidden, it must have not been closed when leaving, and there is no window at the top of the tower to shelter from the wind, it must not be blown open by the wind.

When he looked at it carefully, Yun Yu was more sure of his judgment, and there was obviously a faint handprint on the door panel. Although there is sometimes some dust after leaving, there is obviously less dust on the fingers.

Who would enter this forbidden area?

Seeing God, Yun Yu forgot about himself, and inadvertently took another step closer. But the iron door itself had already been affixed, and further it made a door sound, followed by the sound of iron chains.

In order to prevent the sound from spreading, Yun Yu buckled the chain, and the echo disappeared in an instant, but Yun Yu's hand groped along the chain again, and he didn't find a lock!

Maybe the last time I came, I didn't notice this, and the summer courtyard appeared quickly, and then I didn't care about going up to the top floor, and the iron chain was clearly hung on the door, not locked.

Yun Yu carefully lifted the iron chain layer by layer, until it was completely separated from the iron fence gate, and then slowly squatted down and placed it on the ground.

"Squeaky ......"

There was a rusty sound, and the iron door was slowly opened, and because the sound was too loud, Yun Yu only opened a little bit, enough for himself to enter, and did not pull it out again.

Creeping into the fifteenth floor, Yun Yu could clearly feel that his heart was beating violently, and for a while, the tension had reached the limit, Yun Yu thought to himself: If Xia Yuan appeared at this time, he would be able to scare himself if he didn't make a move.

Walking to the depths of the top of the tower, Yun Yu slightly increased the brightness of the sunstone and placed it on the table, which could illuminate the entire room, after all, there were no stone windows on this floor, so as not to expose the light to the outside of the tower.

For the table, chair, bed and other furnishings, Yun Yu did not have a trace of curiosity or interest, and there was no mystery at a glance.

The bookshelf in front of him exudes a mysterious smell, and with each step closer, the mystery grows, so that the curiosity in my heart has risen to the extreme, and I can't extricate myself.

The bookshelf has six large compartments, each of which is preceded by a wooden panel for a door, and the first one on the right hand is the lattice with the door panel hidden.

In order to avoid leaving a mark, Yun Yu inserted a small iron knife into the crack of the plate, slightly warped, and opened it, but the inside was empty, could it be that his judgment was wrong?

Curiosity was haunted, and once Yunyu opened the other five cabinet doors, and like that grid, they were all empty, without placing anything, not even a blank piece of paper.

couldn't help but gasp, Yun Yu began to doubt his judgment, could it be that he didn't pay attention to the hidden cabinet door or the handprint last time, so that he was carried away by curiosity and broke into this forbidden place that pretended to be mysterious......

Ignoring the dust on the ground, the continuous running at high speed had already exhausted Yun Yu, and with the disappointment of this moment, he sat on the ground, and with the dust that he brought up, it filled a small part of the space in the room.

Yun Yu smashed his mouth and thought: If there is nothing in this place, why should it be a forbidden place? These fifteen floors are no different, and even the aura is not as rich as the thirteenth floor, looking left and right, it is just a storage room for waste furniture, how can there be a need for a forbidden place.

After thinking about it, Yun Yu's encircling gaze finally fixed on the two cabinet doors under the bookshelf, it turned out that there were not only six compartments on the top, but a larger cabinet door as the bottom support, which could also be used to place some things.

After climbing two steps forward, Yun Yu couldn't help but be stunned, there were five finger prints on the cabinet door, which was similar in size to the lattice door panel above, could it be from the same person?

Yun Yu quickly stood up, held the sunstone on the table in his hand, walked into the bookshelf with it, and slowly squatted down, and then the light of the sunstone, the mark of the five fingers was even clearer.

With the aging wooden friction sound, the cabinet door opened left and right, hehe, there is Qiankun inside, Qiankun is here.

In the cabinet door, there are dozens of scrolls, obviously, the larger ones are some priceless calligraphy and paintings, and the smaller ones must be spiritual skills or internal power scrolls, and in this pile of scrolls, the most striking is a delicate red wooden box.

The cabinet door was clean with dust, but the surface of the box was very clean, as bright as a mirror, it was obvious that it had been wiped, so he was not afraid of leaving a handprint, Yun Yu took out the box.

The wooden lid of the box is pull-out, slowly opened, and what appears in front of you is a thick stack of paper, which is close to the size of the box, and it is also just put in, very neat.

There were some incomprehensible handwriting on the paper, although it was sure to be the Lingyu font, but the sloppy style made Yun Yu, who was not a literati and ink writer, confused.

But from the neat self and the format of two or three words, it is not difficult to infer that this may be some internal list of Oga Academy, as for what it is, and who the name is, it is unknown.

Sticking his finger along the gap on one side, Yunyu felt that the bottom of the box was not wooden, but very soft, and from the outside, it was indeed made of wood, which should be a soft cushion.

But no matter what, open it first, Yun Yu grabbed the stack of papers, and then held it firmly with both hands and put it aside.

Under the paper, there is a milky white mat, but it can be seen from the gap that this is a large mat folded and cushioned underneath, Yunyu reached out again, and under the mat was the wooden feel, scooped up the mat and slowly opened it.

Opening the soft mat that was originally facing him, Yun Yu almost exclaimed, what kind of mat is that, it is actually a white cowhide map......

Yun Yu was stunned for a long time, looking at the familiar lines on it, touching the familiar feel, and those familiar map lines.

After looking for a long time from the jade belt, I found the white cowhide map given by Tetan in the past, and gently put the two together, although the lines do not match, but from the stroke of the painter, it is not difficult to judge that it is from the same person's hand......!
