Keyboard Immortal Chapter 863: The secret of King Qin’s gallbladder

"Linear algebra?" Zhao Ruizhi frowned, and he didn't have time to get angry, but was thinking about what kind of magic tricks this is, why have I never heard of it?

Not to mention him, even Mi Li, who had finished reading the library of the Qin royal family, was at a loss. What is linear algebra? Why don't I know?

Only Bi Linglong was thoughtful, thinking of the information he had previously investigated Zaan, he seemed to be the math teacher of Mingyue Academy? Moreover, he went to the National Academy before, and even those teachers Hou Shan, whose eyes were higher than the top on weekdays, admired his profound knowledge. He thought that linear algebra should be one of his abilities.

Zuan confirmed their inscription to Zhao Ruizhi again, and muttered to himself: "Xuanyun is to Tianmen, it is to describe the situation when we went to the island before..."

But the latter statements involve ancient astrology, which Zaun doesn't know too well, but luckily he has an active woman by his side.

He hurriedly asked Mi Li, and only then did he roughly understand the secret in the inscription.

Tianmen belongs to Spica in the twenty-eight constellations, and Tianri naturally refers to the sun behind. Historically, Jinque generally refers to the palace where heaven and earth live, while Ziweiyuan in ancient astrology corresponds to the residence of heaven and earth.

Ancient astrology divides the sky into three constellations and twenty-eight constellations. Three constellations are three vast constellations in the sky above. Each constellation contains many constellations and stars, known as Ziweiyuan, Taiweiyuan, Sky City Wall.

Then the constellations near the ecliptic are turned into twenty-eight regions, which are called twenty-eight constellations. The twenty-eight constellations are grouped into groups of seven, and can be divided into four images of Qinglong, Suzaku, White Tiger, and Xuanwu according to the south, east, and northwest.

The southern star should be the guide star, the star of the seven stars in the north; Yuheng should refer to the Yuheng star of the Big Dipper. It is difficult for the southern star to orbit the Big Dipper according to common astrological phenomena, which is why the previous emperor was so desperate , but now this slate corresponds to the starry sky, you only need to match the respective signs, you don't need to really pull the stars.

Huangai means purple, cangai refers to the Canopy star of Ziweiyuan, and purple refers to Ziwei Dixing;

Yayin entered Zheng, Yayin refers to Xia Yin in ancient times, and Xiaren is Xuanyuan after Xuanyuan, it should refer to Xuanyuan star in the constellation; Zheng refers to Zheng Xing in the city wall.

With Mili's help, Zaan quickly deciphered the secret in the inscription, and all that remained was to align the corresponding constellations.

This kind of movement of one pillar will affect several other pillars to rotate together. It is easy to brute force cracking if it is simple, but it is obviously useless to randomly try a relationship as complicated as the inscription.

However, although this ancient mechanism is mysterious, it should not be difficult for a university-educated person. It is completely a linear algebra application problem.

He first arranged the order of each column, the first column was rotated once, and the number of times of the corresponding other columns was recorded. Assuming that the second column did not rotate, it was recorded as 0, and the third column was recorded as 1 once. The quadratic rotation is recorded as 2, and so on, and finally it can be recorded as d1=[1, 0, 1, 2...]T (Note: Here T is a superscript, which means transposition, and the mathematical symbols of the codeword software are marked does not come out).

Then set the first column to be rotated X1 times, then the state of the column will become X1*d1;

Then set the second column to rotate X2 times, then the column status will become

X2*d2;

And so on, the final state of the column is X1*d1+X2*d2+X3*d3+…=b.

b is a certain constant, because according to the previous inscription information to determine which patterns correspond, it is possible to determine the final state of each pillar and how many times it was rotated at the beginning.

This is equivalent to solving an inhomogeneous linear equation system, X1, X2, X3... can be solved, which corresponds to rotating the corresponding column several times, and the state described in the inscription can be achieved.

Zhao Ruizhi watched as Zaan drew some symbols on the ground that he had never seen before, exactly like reading a book from heaven.

He couldn't help but secretly glanced at the other people, and found that whether it was Bi Linglong or He Li and others, they all had mentally retarded and confused expressions on their faces, and his bursting mentality instantly calmed down a lot.

After a while, He Li, who was next to him, couldn't help but sneak a peek at him, and found that Zhao Ruizhi was watching the ghosts painted by Zu An and kept nodding slightly. The emperor really deserves to be the emperor, even this can be understood.

After a while, Zaun finally stood up: "Okay!"

He then came to the slate array, thinking about the answer he just calculated, and turned the corresponding pillars a few times.

As expected, after turning it in this order, all the patterns are aligned!

Then there was another roar from below, apparently the mechanism was starting to work.

Suddenly, a ray of light appeared on the entire slate, and then the rays of light rose rapidly, and the night pearls that were placed in the potholes all lit up.

A beam of light passed between those luminous pearls, and finally hit a certain spot on the slate. The slate was obviously inclined at an angle.

But after a while, nothing happened, Zhao Ruizhi frowned: "What's going on?"

He wasn't in a hurry to ask for guilt, because the previous indications were that Zaun's solution was correct. Is there something wrong?

He didn't have the slightest clue after thinking about it for a long time, so he looked directly at Zaan. As the emperor, of course, he didn't have to do everything himself. The headaches were left to his subordinates to think about.

Zuan is also confused, everything is going well, why didn't anything show up?

At this time, Mili's voice suddenly sounded: "Do you remember the last sentence of the stone tablet we found?"

"The moon enters the center for the noble..." Zaan read that sentence silently, noting that the slate illuminated by the beam of light had a slightly sunken groove, and the shape of the groove seemed to be like a mirror.

With a move in his heart, he took out from his arms the gallbladder mirror that King Qin had found in the treasury of Liangtian Biyuejiao before. Sure enough, the shape was just right.

Zuan had tried every means to activate this mirror after getting it before, but unfortunately it was like a dead thing from beginning to end, and it didn't move at all.

But at this moment, that beam of light shines on the mirror, and it has been silent before, and it suddenly shines brightly, like a small sun, making people unable to look directly.

I saw a bright light shot from the mirror, shot straight into the sky and shot to the third immortal island, I don't know where.

Then a shocking thing happened, I saw a bright yellow light more than ten feet wide slowly spread down from the third immortal island.

Yes, it was spread like a carpet, and it didn't take long for the light to reach the second immortal island.

Then the second immortal island was facing their direction, and there was also a bright yellow light spread over, and it was soon embedded near the slate array, forming a transparent line between the two islands. light bridge.

When the bridge of light was formed, the bright night pearl light on the stone slab slowly disappeared, and the King Qin's bile mirror returned to normal.

Zuan hurriedly took it back, it was clearly a treasure, and he couldn't bear to leave it here.

Zhao Ruizhi glanced at him, and obviously realized that his mirror was extraordinary. He was about to grab it and remove Zaan, but he immediately thought of what the other party just said, and saw his ability to draw talismans. I thought that this guy is really good at solving these organs, so let's wait first, there is still some use for him if there is no guarantee in the back.

Pressing the murderous intention in his heart, he walked to the bridge of light alone.

I was a little cautious at first, but I soon discovered that although the light bridge looked transparent and scary, it was like a solid step on it, and there was no fear of falling.

"Is this the method of the Xianjia?" Zhao Ruizhi looked at the palace in the distance, his eyes became more and more eager, his figure turned into an afterimage, and he soon landed on the second island.

He Li and the others hurriedly followed after seeing this. After all, there might be a fairy tale in front of them, and who wouldn't want to take a piece of the pie.

Zuan screamed a pity, just now he tried to close the light bridge and took the opportunity to kill the emperor, but unfortunately, whether it was beads or pillars, they seemed to be welded to death and could no longer be moved.

"Forget it, let's find other opportunities later." Zaan also took Bi Linglong to the bridge of light.

Bi Linglong was shocked all the way, and looked around at the Guangqiao with excitement everywhere.

Zuan's previous life has seen many such scenes in various Xianxia movies and TV series and various games, so naturally there is nothing new.

He silently took out the King Qin's gallbladder, which seemed to have been activated just now. I don't know what function it has?

It's a pity that I held it in my hand and studied it for half a day, but it was still unremarkable and could not see any difference at all.

"Is it just my delusion?" Zaun frowned,

As he was about to take back the mirror, Bi Linglong suddenly came to him: "What are you looking at?"

At this time, Zaan was holding the mirror, and Bi Linglong was standing behind the mirror looking at him suspiciously.

Zuan looked down at the mirror and saw two nosebleeds in an instant.
