In front of the fire attribute bookshelf, Long Yuan and Long Rou separated, and in the envious eyes of everyone, Long Rou walked up to the second layer.

Watching Long Rou go up to the second floor, the children hesitated for a moment, as if they suddenly understood, even if they couldn't choose the scroll on the second floor, it must be okay to look at it, the old man in the white robe only said that he was not allowed to take more, and he didn't say that he was not allowed to look at it, thinking about this, suddenly a few children who had chosen the scroll followed closely to the second floor.

Children, always full of infinite curiosity. Long Yuan looked at the backs of those children and thought funny.

The fire attribute exercise scrolls are far less than the other attribute scrolls, and more bookshelves are vacant, and soon, Long Yuan finished reading those scrolls, and he was not very satisfied, and the exercise level was also above the third level, helplessly, Long Yuan finally chose a third-level subordinate master scroll called Heart Control Fire, this scroll has the characteristics of enhancing the spiritual energy of the subordinate teacher, and Long Yuan intends to use it together with the mimicry technique in the future.

Looking up at the second floor, there is a lot of time anyway, go up and see what scroll Long Rou chooses, and then look at what kind of exercises the fire attribute scrolls above the junior subordinate master are, thinking about Long Yuan, he took the scroll and walked up to the second floor, when he went up, Long Yuan suddenly found that from the bottom of his heart, he was also a curious child, or rather, everyone was a curious child?

At the beginning of the second floor, Long Yuan couldn't help but feel a cold breath rushing towards him, the area of the second floor is also quite large, the original wooden bookshelf has also become a stone bookshelf, the blue-gray color seems to reveal a cold feeling, on the first two floors, Long Yuan found that the bookshelf at the door is the fire attribute, and he opened a scroll casually, and the four black characters of the flame ring are clearly displayed, and after a cursory introduction, this kind can compress the energy of the division into an energy ring for attacking skills, and the cultivation level is seven.

Putting down the ring of flames, Long Yuan was about to take down a scroll, when his heart suddenly tugged, and an inexplicable feeling came to his heart, that feeling, it seemed that something was calling him, and that thing was on the second floor at this time.

Looking up at the staircase leading to the third floor, that feeling was even stronger, what would be something looking for and summoning himself in this library pavilion? With doubts, Long Yuan turned around and walked towards the third floor of the stairs, and as soon as he stepped up the stairs of the third floor, he heard the voice of an old man suddenly sounding above the stairs: "Little friend, these three floors are not something you can go up to, let's go down!" This voice was the same as the one who was talking to the old man in white robe at that time, and it was the person who was called the old ghost by the old man in white robe.

Stopping, Long Yuan frowned slightly, and looked at the top of the third floor, due to the light, it was black and mushy, and he couldn't see anything, "I just want to go up and have a look, I don't have any other ideas, can't I?"

The other party seemed to be a little surprised by Long Yuan's answer, under normal circumstances, after being said like this, the children would retreat down the stairs, just like just now, but this child insisted on going up, and judging from the demeanor and tone of the answer, there was no panic in the slightest, just like an adult.

"It's okay if you insist on going up, but the things on the third floor want you not to move, and those things are not something you can touch. The black old ghost didn't know what Lu Dao was for, to say that he would never let these children go up to the third floor, but in the face of Long Yuan, he had a strange feeling, he felt that Long Yuan went to the third floor was not simply curious, he wanted to know what Lu Dao, what did this child want to do on the third floor.

"Thank you. Smiled and nodded, Long Yuan walked up to the third floor step by step, when he walked up, a stream of cold air came down from the third layer, and when he reached the top floor, it was even more cold Long Yuan's body couldn't help but shiver for a while, and above the third layer, Long Yuan suddenly entered a white world, the third layer is completely different from the first and second layers, the entire third layer seems to be surrounded by a white stone, the white stone is surrounded by a faint white mist, looking around, in the middle of the white stone, a small space was taken out, and there were scrolls of scrolls in the small grid。 ...,

His eyes swept over those scrolls, and Long Yuan continued to walk towards the fourth floor without hesitation, going up to the third floor, the feeling of calling was even stronger, Long Yuan was already able to determine that it was something on the fourth floor that was calling him, gifts? Suddenly, Long Yuan remembered last night's dream......

"I ...... I got a gift for you......"

"Could it be ......," muttered in a low voice, and Long Yuan stepped onto the fourth-story staircase. The black old ghost in the dark laughed secretly in his heart, I don't know the height of the sky, it's already good to let you go up to the third floor, but I want to go up to the fourth floor, the stairs between the third and fourth floors are set up with formation protection, without his lift, whoever wants to go up will be bounced out, silently, the black old ghost waited for Long Yuan to be deflated by the rebound of the formation.

"Wow, ......" Long Yuan's footsteps on the stairs sounded continuously, and the expected rebound did not appear, and the black old ghost in the dark stared widely, this ...... What the hell is going on? It doesn't feel good, the old black ghost immediately went to sense the defensive formation on the stairs, and after a second, the old black ghost felt a chill all over his body, and the defensive formation from the third layer to the fourth floor was actually broken?

It's not good, there is something wrong with this kid! Thinking about it, the old black ghost also appeared, and followed up to the fourth layer, and the subordinate master's exercises above the fourth layer had reached the master level, and he couldn't afford to lose every scroll of exercises.

When the black old ghost ran up to the fourth floor, he was faced with a quiet back, at this time, this back stood silently in front of a sandalwood table, and the black old ghost remembered that there was a fire attribute scroll on the table, and that thing......

Turning his head slowly, a slightly immature little face was so calm, "Heh, you are the one who spoke, don't worry, I won't move things without your permission." The boy said lightly to the old black ghost.

Feeling his gaffe, the black old ghost straightened his robe, moved lightly, came to the boy in a few steps, and looked at the boy carefully, at this time, the black old ghost suddenly found that the fifteen-year-old child, the immature breath on his face seemed to reveal a mature breath, that kind of calm feeling, not at all like a child can have, with doubts, the black old ghost turned to the sandalwood table in front of him, at this time on the table, there were three fiery red scrolls and a red and black box, there was no trace of passing.

"Whew......" exhaled softly, the feeling of being summoned had disappeared at this moment, Long Yuan's gaze fell lightly on the table, or on the red and black box with seven corners, Long Yuan confirmed, after a long time, it was this thing that summoned himself, Long Yuan was very curious, a box, can summon himself, or rather, the things in the box. "I ...... Can you take a look at the contents of this box?" Long Yuan asked the old black ghost who was standing in front of him wearing a black robe.

The corners of his mouth showed a strange expression, and the old black ghost began to recall the things about this seven-sided treasure box in his mind, and when he wanted to talk about it, he had to recall it fifteen years ago, one day fifteen years ago, he happened to be on duty that day, and when he was also patrolling as before, he suddenly found that in the middle of the hall on the fourth floor, there was one more person at some point, and that person was covered in a black cloak, and he stood silently in the hall like that, a kind of coercion from the soul attacked, so that the black old ghost couldn't move his whole body, as if the other party only needed to move a finger, and he would disappear into this world。

"Are you the guardian of this library?" a deep voice asked slowly.

"Yes, I'm ......" fully mobilized the energy of the subordinate teacher in his body, and the black old ghost finally barely resisted the pressure and returned with difficulty.

A pair of iron armor stretched out from the cloak, and in his hand, he held a red and black seven-sided box, "The name of this treasure box is the seven-sided treasure box, I put it here, and in fifteen years, someone will come to pick it up." As he spoke, the black-robed man placed the box on the fire attribute table. "Whew......" A gust of wind blew, and the black-robed man disappeared silently in the next second.

"Remember, you don't need to do anything, and don't do anything, otherwise, you will disappear from this world......" Just when the black old ghost breathed a sigh of relief, the voice of the black-robed man sounded in the ears of the black old ghost again, the voice was cold and cold, without any emotion, and the black old ghost felt that the cold hairs on his whole body seemed to stand up at this moment.

After waiting in place for an hour, the old black ghost really confirmed that the man had really gone away, so he dared to sit down on the ground, and then he realized that his back was covered with cold sweat, but he didn't realize it at all. Looking at the red and black seven-edged treasure box, the old black ghost has complicated feelings!
