Nine palace gossip --- originated very early in the history of Yang Yi in the previous life, and there is a record in the ancient Fuxi period of the river Tuluo book, the nine palaces, is to divide the heavenly palace into a tic-tac-toe Qiangong, Kan Palace, Gen Palace, Zhen Palace, Middle Palace, Xun Palace, Ligong, Kun Palace, Dui Palace nine equal parts, Qimen Dunjia Houtian Bagua, Luoshu, 24 solar terms, space, and number to match to form the basic pattern and structure. This pattern and architecture is multidimensional.

Time, seasons, spatial orientation, astrophysics, odd door formations, numerical arithmetic, it can be said that the nine palace gossip has been widely derived and used in countless fields, and the most important thing of numerical arithmetic has been mentioned relatively little, in most of the Confucianism period, specializing in arithmetic is not considered orthodox, and even reduced to a singular skill.

A seemingly simple nine-square diagram is actually unpredictable, and in later generations, a modern mathematician took three months to make a pair of Sudoku nine-square grids known as the world's most difficult, and I don't know how many people's brain cells were burned.

What makes Yang Yi secretly happy is that the bluestone sixteen palace diagram on the altar is just a simple nine-square grid derivative diagram, if the flower patriarch also comes to a Sudoku nine-square grid, it is estimated that even Yang Yi will have to count it for several months, but in this era, it is estimated that no one knows what Sudoku is.

Moreover, if the normal method of cracking is followed, this sixteen palace gossip diagram should use the five elements of the eight trigrams, in order to restrain each other, hexagram position array gate and other ancient metaphysical knowledge, this is a huge and extremely complex method of position, it takes a long time for a knowledgeable person to decipher.

Yang Yi, as a traverser, stole a trick, replaced the five elements of gossip with corresponding numbers, and then used the laws of the nine palaces and sixteen palaces summarized by later generations to play a complex set of nine palace gossip Qimen Dunjia formations into a number game.

Yang Yi wrote down the arrangement of the formations in his heart, and hurriedly slipped down from the stone pillar, and exclaimed urgently: "Pen!" Pen! Who has a pen! ”

He Qu saw that his expression was solemn, and he seemed to really see what was the doorway, and he took his Tiehao pen and asked, "The old man's pen lends you!" ”

Yang Yi stared at the iron pen that was thicker than a steel drill, and scolded in a low voice: "Neurotic... Such a big 2B pen can only be used by you in this 2B... Damn.."

Seeing that he couldn't find a pen and paper, Yang Yi simply sat on the ground, picked up a bluestone fragment, and began to carve coordinates on the slate, calculating the number of sixteen square grids.

Master Chan Zhan, who was standing on the side, waved his hand to stop He Quai, who wanted to get angry, and everyone stared at Yang Yi, who was squatting on the ground and calculating attentively.

Time passed minute by minute, Yang Yi would sit for a while, squat for a while, scratch his head from time to time, and touch his chin from time to time, he only hated himself for being a liberal arts student before, if he was a modern person with solid mathematics, it was estimated that he would be able to calculate it in less than half an hour, and Yang Yi's head was about to explode, but the progress was not fast.

The sky has gradually darkened, Yang Yi doesn't know how long he has been counting on the ground, during this period, He Qu has been sick for a long time, and Master Chan Chan has also stood by and observed for a long time, but no one can understand what these messy symbols Yang Yi painted are, but one thing is for sure that he must not be scribbling, because those symbols seem to be arranged extremely neatly.

Yang Yi naturally didn't worry about what they could see, if they wanted to learn Arabic numerals, they had to take a 108,000-mile journey to India.

There was no moonlight tonight, and Yang Yi's eyes, which had been concentrating since it got dark, were sour. Suddenly, the day next to him brightened, and when he turned his head, it turned out to be a flowery saint dressed in white holding a torch to help him illuminate.

Yang Yi was stunned, the flowery saintess under the blazing fire was very beautiful, although the veil covered her face, but those crystal eyes allowed Yang Yi to see her figure from inside.

Seeing Yang Yi staring straight at herself, the Blossom Saintess gently shook the torch in her hand, Yang Yi came to her senses, smiled a little embarrassedly, and went down to continue to calculate.

Another two hours passed...

"There it is! Damn it! Yang Yi suddenly clapped his hands and fought, looked at the neat sixteen-square grid number map on the ground, and smiled with satisfaction: "Please call Lao Tzu Xueba!" ”

Everyone raised their heads to look at Yang Yi, and He Quzhi hurriedly walked up, staring at the strange symbols written by Yang Yi, and said suspiciously: "Have you developed this gossip array?" ”

Yang Yi smiled: "Just because you're stupid doesn't mean that everyone else is stupid, we're going to break the formation, and the idle people get out of the way." ”

He Quai's face was embarrassed, he used to be the oldest qualified elder in the Blossom Valley, and the way of the formation was incomparable, but when he arrived at Yang Yi, he became an idle person, and said coldly: "Hmph... You don't have to fall into the hands of the old man, otherwise you will not be able to live or die! ”

Yang Yi smiled, knowing that this guy was worried about the exercises of the Junxin Knife, even if he was kind to him, he couldn't treat himself well, and he naturally couldn't miss it if he could take advantage of it.

Seeing that He Qu was sick and left, Yang Yi came to the bustling saintess. The Prosperous Saintess also looked at Yang Yi and said suspiciously: "You really see the method of breaking the formation?" ”

As the saintess of the Valley of Flowers, she naturally knew how many people in the past generations had tried to find the relics of the ancestors, including many martial arts masters and sages of the time, but no one could enter for hundreds of years.

Yang Yidao: "The method is eight or nine, and only God knows whether it can succeed." ”

The Blossoming Saintess nodded, it is useless to say more now, she can only use the dead horse as a live horse doctor, and she will listen to Yang Yi's explanation intently.

"This altar is actually a Bagua Sixteen Palaces map, I have guessed the direction, after you remember the Bagua position later, you and I will enter the formation at the same time, and then step on the stone slab on the ground with the steps of the king."

"Remember, the pace must be synchronized, which is why you must learn the Junxin Sword and the Ruoyi Sword to open the entrance,"

The Prosperous Saintess nodded, then said no more, and listened attentively to Yang Yi's explanation of the method of cracking.

In the thick of the night, the two of them each walked to the side of the stone pillar, entered the bluestone formation from the position of innate gossip and acquired gossip respectively, and stepped into the formation according to the mantra of the Junxin Sword and the Ruoyi Sword. The two of them are not proficient enough to learn the exercises themselves, especially Yang Yi is still in contact with martial arts for the first time, and they can't find the key for a while, and if they accidentally take a wrong step, or if the pace is uneven, they have to start all over again.

"Hey! Wait, I went wrong, start over! ”

"Wow! Wrong again, come again! ”

"Wrong, come again...."

Under the gaze of everyone, the two of them have been repeated, and they don't know how many times they have walked, the prosperous saint has a deep foundation and quickly mastered the trick, and Yang Yi has gradually become proficient in the exercises, the only problem is that the two of them are difficult to have the same mind, and it is difficult to reach the realm of Zhang Junxin and Shu Ruoyi.

I don't know how many times the two have tried, and they have been failing and starting all over again, but each time it seems to be a few more squares out of the box than the last time. Yang Yi was embarrassed from the beginning, and gradually had a bit of domineering meaning of the Junxin knife, and the broken knife of Zhang Junxin in his hand made it no longer so difficult, and the steps under his feet also seemed elegant and skillful.
