It is very dangerous to be distracted in battle, Xin Yao only cared about observing Aunt Lu, and forgot that she was in danger for a while. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

only heard a loud noise, countless gravel fell, Xin Yao couldn't dodge, and was almost hit on the head by the gravel, but Binlu reacted in time, dragging Meng Qingzhi and Xin Yao from left to right and quickly rushed away from here.

Xin Yao saw that Aunt Lu was clearly struggling forward, her arms were level, maintaining her body balance at high speed.

So, where does the power of hugging your waist come from? This is clearly an empty sword, and you can do whatever you want.

Binlu rushed to the outside of the corridor with lightning speed, and when he looked back, it turned out that Binlu's attack on the back of the head of the tenth male stone statue completely defeated the stone statue, and that loud bang was the thick wall at the end of the corridor, slowly opening.

The mechanism of the long corridor of the man's stone statue was solved by the joint efforts of the three of them.

Finally waited until there was no movement on the other side of the corridor, the three of them cautiously approached again, only to see that on the other side of the wall, there was still a corridor, but the next corridor had no stone statues, it seemed to be open, and the three of them looked around while continuing to move forward hand in hand.

The three of them were vigilant, cautious, and step-by-step, but they came to the end of the corridor unimpeded, which was quite surprising.

"Great, this corridor is not dangerous." Binlu rejoiced.

"Aunt Lu, although there is no danger, I can't find any way to crack the mechanism." Xin Yao looked around, the corridor was empty, although there was no crisis, but there was no life.

Xin Yao was reasonable, the three of them wandered in the corridor for a long time, there were no caves, no stone statues, no abnormalities, and the biggest abnormalities.

The ground was smooth ice, the walls were as bright as new, and when you touched the flat wall, you could only feel a chill from your heart, and you couldn't even touch a single protrusion, let alone a mechanism.

"Hey, it's ice on all sides, it's bare, it's slippery, how can you open the thick, hard wall at the end of the corridor." Binlu said in frustration that she would rather fight with those stone statues now, at least with a clear direction.

Meng Qingzhi suddenly thought of something, and he walked to the stone wall at the end of the corridor again, stopping and thinking deeply.

"Why don't we attack this stone wall together, and we force a breakthrough?" Binlu suggested.

"Wait, little aunt, this stone wall is the only place in the entire corridor that is not flat, maybe the mechanism that opens the stone wall is hidden in the stone wall itself." Meng Qingzhi touched the uneven wall, some of the small stones were quite sharp, and there was still pain in his hands.

Suddenly, Meng Qingzhi touched a small protruding stone, and with a little force, the stone was pushed, and it turned out that these sharp small stones were actually movable.

Meng Qingzhi hurriedly took a few steps back, taking in the entire stone wall, his brows were deeply locked, the arrangement of these small stones seemed to have another mystery.

Looking at these small stones, Meng Qingzhi obviously felt very familiar, but he couldn't explain why he felt familiar.

"I counted the small sharp stones, a hundred and seven in all." Xin Yao had nothing to do, counted the stones, and didn't know how to help.

Meng Qingzhi suddenly had an epiphany, sharp stones can move, but sleek stones can't, he quickly counted the sleek stones, which are also one hundred and seven, there must be some mysterious clues hidden in them, and this clue is the key to cracking the mechanism.

"Those who are dissatisfied with the law will be ordered by the law; His mother is the same as him, and he is directly subordinate to him. Meng Qingzhi muttered to himself, sometimes touching the smooth stone, and sometimes pushing the sharp stone.

Binlu and Xin Yao silently retreated and stayed quietly not far away, lest they disturb Meng Qingzhi, who had already fallen into a trance.

Meng Qing's mind flew over, he kept fiddling with the stones, and every time he moved a sharp stone, he would stop his movements and silently calculate in his heart, which piece to push next, and said something that Binlu and Xin Yao couldn't understand at all.

"I see, I see, it's so simple." Meng Qingzhi's thinking became clearer and clearer, and he pushed the stone for a whole hour, and now it finally became clear.

"What's the easy way?" Binlu tried to interact with Meng Qingzhi, which was the only thing she could interact with from Fang Cai to now.

"Stand back and watch me push the last little rock." Meng Qingzhi instructed.

"Aren't we standing back enough?" Bin Lu said with a smile, Meng Qingzhi was so focused that he and Xin Yao had been standing far away for a long time, and he didn't notice it.

Meng Qingzhi saw Binlu and Xin Yao not far away, he smiled awkwardly, and then his finger landed on a sharp stone in the upper left, and with a little force, the stone was pushed downward.

After the stone was pushed into place, Meng Qingzhi hurriedly retreated, and with it, a familiar loud sound rumbled throughout the corridor.

The stone wall was opened, there was no fighting, no effort was expended, just a few stones were pushed by Meng Qingzhi, and it was easily opened.

"Aoyuki, you're amazing!" Xin Yao admired from the bottom of her heart, and her eyes looking at Meng Qingzhi were full of love and admiration.

"What is ordered by the Dharma, and what is directly obeyed, is this the inner strength of the mind?" Binlu also secretly said to himself, Meng Qingzhi, this kid, does have two brushes, and I don't know what method he used to unlock the mechanism.

"Oh, those are not the inner strength of the mind, but the content of the nine chapters of arithmetic, namely decay, lessenance, equations, and Pythagorean." Meng Qingzhi explained,

"Listen, I don't understand." Bin Lu shook her head sneeringly, what is the decay is less wide, the equation Pythagorean has never heard of it at all, but she has heard of the nine chapters of arithmetic, it seems to be a particularly complex and mysterious mental technique, right?

"In short, I found that there were some patterns in the number series and shape of these stones, so I tried to rearrange them according to the rules by solving the equations, and I didn't expect to succeed." Meng Qingzhi patiently explained.

In the library of the Western Desert Sect, in addition to the internal strength of the heart method and the major pharmacopoeia, there are also nine chapters of arithmetic and various formation books, which are just these ancient books left by the ancestors, and no one has ever read them.

The Northern Sect moved out of the Tianshan Mountains, and all the books in the Library Pavilion were copied, even if it was an ancient book that could not be understood, Master Yang Lin also asked to carefully copy it word for word, in case he met a disciple who understood it.

For the study of formations, Meng Qingzhi can be said to be self-taught, and no one in the Northern Sect taught him any knowledge of formations and arithmetic, but Meng Qingzhi held a book, studied and explored alone, and read the book a hundred times to see the meaning of it.

Meng Qingzhi felt that the nine-chapter arithmetic was a very interesting knowledge, although the content was unfathomable and looked like a book from heaven, but after mastering the nine-chapter arithmetic, he would find that in fact, many small details in daily life could be applied to the nine-chapter arithmetic.

At that time, Meng Qingzhi turned over all the books in the library because of his personal interest, but he didn't expect that it would come in handy at the moment.
