"It's regular, these seven spaces are filled in with unfilled numbers from 1 to 36......"

Song Yang quickly filled in the seven blanks, "Look, it's like this now:

28~43~4~3~35~10

36~18~21~24~11~1

7~23~12~17~22~30

8~13~26~19~16~29

5~20~15~14~25~32

27~33~34~6~2~9

……”

"What's the mystery?" Mu Yuhan looked left and right, but did not find any rules.

Notice that the sum of the six numbers in each row, column, and two diagonal lines of this magic square is equal, 111. For example, the sum of the six numbers in the first row is 28 + 1 + 3 + 31 + 35 + 10 = 111.

This sixth-order magic square is not an ordinary magic square, it also has two unique properties.

First, the magic square is a quadratic magic square. The sum of squares of the six numbers in the first and sixth rows of the magic square is also equal:

28^2+4^2+3^2+31^2+35^2+10^2=3095

27^2+33^2+34^2+6^2+2^2+9^2=3095

The sum of squares of the six numbers in the first and sixth columns is also equal:

28^2+36^2+7^2+8^2+5^2+27^2=2947

10^2+1^2+30^2+29^2+32^2+9^2=2947

Conventional squares do not have this property at all.

This is not the main thing, the key is here, this magic square removes the outermost layer, and the remaining part in the middle is still a fourth-order magic square. You see, this fourth-order magic square is made up of 16 numbers from 11 to 26, and the sum of the four numbers in each row, column, and two diagonals is 74. Like what

18+21+24+11=74

20+15+14+25=74

21+12+26+15=74

24+17+19+14=74

What's even more peculiar is that this fourth-order magic square is still a perfect magic square. It is also called magic paradise, that is, the sum of the 4 numbers on each pan-diagonal is also 74.

For example, 18 + 15 + 19 + 22 + 74

Magic squares of this nature are rare. As you can imagine, the difficulty of designing such a magic square is breathtaking. ”

"It's so complicated, what does it have to do with the agency?"

"The magic square has a very close relationship with the Bagua I Ching. Bagua, the so-called "Taiji gives birth to two instruments (that is, yin and yang), two instruments give birth to four elephants (that is, less yang, sun, less yin, too yin), four elephants perform eight trigrams, eight eight sixty-four trigrams, this is Fuxi gossip, also called innate gossip. These 8864 hexagrams, Qianyi, Dui2, Li3, Zhen 4, Xun 5, Kan6, Gen7, and Kun 8 are all ranked into the 64 Hexagram Hexagram with a difference of 9 numbers, and the 36 hexagrams are all ranked into the Magic Quadrant Hexagram with the difference of 7 numbers.

A small Zhou Tian is the sixteen hexagrams, look, this perfect magic square is exactly the Zhou Tian sixteen hexagrams. So there is the structure of the entire tomb in it, if you don't understand this, after entering it, it will be a big labyrinth, but if you take the wrong step, you will lose everything......"

"......" Mu Yuhan only felt that there was a gold star in front of him, but he didn't expect that an iron plate actually hid so many things, and the handsome face that looked at Song Yang began to light up.

"Even," Song Yang pointed to the eight doors around him, "Among them, only this one is the door of life, and that one is the door of death, it is estimated that there are a lot of organs inside, and there are many bad people who break in, and his six doors should be the number of mazes, of course, except for the door of death, we can go in and have a look, follow me ......"

Death door, I didn't dare to break into it easily, and find out. But in addition to the other six stone gates of life and death, they are twisted and twisted, like a labyrinth, but they are actually all connected. It took two hours before the two of them came out in a circle.

"Let's go, let's take a look inside the door, I guess something is also in here."

The closed door opened a dark gap, and it was impossible to see inside.

There was a faint outline in the darkness, and it was impossible to see what was inside, and then suddenly a little light appeared, like a green lamp being lit, which was dispelling the darkness around it, leaving a bright scene, swaying, fluttering like the wind, and with the flames swaying from side to side, the brief light began to flicker.

Ah, after passing through the darkness, the vision suddenly opened up, and a large hall appeared in front of me, and there was a cave inside, which was actually a natural grotto.

"It's so big, there's an opening here to go out, you see, it's going up the mountain again, it looks like there are mountains and water, and there is the sound of a waterfall, it's not right, so why doesn't anyone find out?" Mu Yuhan said strangely.

"In the whole burial chamber, the corridor is all the way down, and it is possible that we are in a closed valley and cannot enter at all." Song Yang had a suspicious look on his face.

"Well, the place chosen by the ancestor is really good."

Directly above the main hall, two statues are side by side, holding each other with one hand, and in their hands, there is an iron plaque.

Mu Yuhan hurriedly stepped forward, pulled it out, and after carefully examining it, crystal tears began to flicker.

"Grandpa, I found it, I found it!"

"How so? Isn't that right? He muttered to himself.

"What's wrong? What's wrong? ”

"Isn't it said that there is always treasure in the tomb? How could there be no such a good place to hide treasures? ”

"Why are you so money-obsessed?" Mu Yuhan, who was still excited just now, suddenly had a cold face.

"I didn't say I wanted to take it, I just appreciated and appreciated, as the saying goes, everyone has a good heart......

"Crooked!" She asked.

"Crooked reasoning is also justified." Song Yang argued.

"Don't pretend, I know you're not that money-addict." She actually said.

"Oh?" Song Yang had doubts, she knew herself so well.

"You're preoccupied, and now, you're pretending too much! I noticed it then, or I would have ...... you in the first place," she whispered.

"Ah......" Song Yang was speechless, he didn't expect that last time he thought he was hunting, it turned out to be ......

"Coming in from the raw gate, in the aisle, there are so many plants here, but the flowers are so black and beautiful,"

She reached out and plucked one, wanting to put it in her nose and smell it.

"Don't!"

Song Yang stopped.

"How?"

"Don't you think there's something wrong with this flower?"

"I think it smells good."

"Incense, but that's a black mandala, the seeds are medicine, but the fragrance of flowers is poison, so in a closed environment, if we stay for an hour or two, we will all be fascinated, and it's not easy to live in the door."

"Mandala Flower ......"

"Let's go back to the hall and take a closer look, I may still have overlooked, there should be something I haven't found. You can't stay here for a long time, especially inside, the smell is too strong. ”

The two had just returned to the hall.

She suddenly "shh......h
