"I really didn't expect that there would be artificial buildings under this abyss!"

Li Daoyi, who was walking in the underground passage, looked around, "I don't know how those ancients came down?" Tsk, this is not a project that can be completed in a short period of time......"

"Alas, it's all done with human life...... What does that mean? The people are suffering, and the people are suffering! ”

Liu Ru's crisp voice is as pleasant as a silver bell.

"Huh? You see, the passage ahead has widened! ”

Wei Zede paused, he pointed to the passage ahead and whispered.

This is the junction of a very different passage, from where the passage expands from the width of three parallel to the width of ten.

Just as Wei Zede and the others were observing, a firelight suddenly lit up from their side and snaked forward.

"What's going on?"

Wei Zede hurriedly looked sideways, only to see Liu Ru sticking out his tongue in embarrassment and explaining, "...... I saw that there was a 'rope' here, so I wanted to get closer and see what it was...... I didn't expect it to burn on its own! ”

Just as Liu Ru was explaining, the ignited flames had turned into two fire dragons, illuminating the passage ahead.

"Look! The layout here is obviously 'Double Dragon Spitting Pearls'......"

Professor Liu observed fixedly for a while, and said in a deep voice, "...... This 'double dragon' is supposed to allude to the flames on both sides, and the 'bead' is supposed to be the mechanism that opens the passage ahead. ”

"Be careful, everyone, don't act rashly!"

Li Daoyi's face changed, and he repeatedly instructed and emphasized the danger here.

Then, the group focused their attention on the chessboard-like cyan slabs in the passage ahead.

"Except for the layout of 'Double Dragon Spitting Pearls'...... This is still a 'Nine Palaces'! ”

Wei Zede muttered to himself: "The nine palaces, that is, two or four are shoulders, six or eight are feet, three on the left and seven on the right, wearing nine shoes and one, and five in the center." ”

Li Daoyi said: "That's right! Moreover, this 'Nine Palace Diagram' is also a kind of 'Nine Palace Diagram'...... You see, the floor of this passage is made up of ninety-nine-eighty-one bluestone slabs. ”

"Isn't this a nine-square grid?"

Liu Ru suddenly realized: "We can go over as long as we follow the law of numbers......"

"That's not right!"

Li Daoyi retorted: "It's not that simple! If you consider the layout of 'Double Dragon Spitting Pearls', the law of this 'Nine Palaces Diagram' has changed a lot! ”

"What then?"

Liu Ru blinked her eyes and asked, "Could it be that we have to go back the way we came?" ”

"If we want to get through it alive, then we must find a 'way to live'!"

Wei Zede calculated: "The ancients were cloudy, and life and death were reversed...... Anger turns upward, like a sheep's horn and rises, ......"

That is to say, from the perspective of the five elements, walking with the sky is left-handed, and going against the sky is right-handed. The so-called 'shun life and death, left-handed master is also born', which should be the meaning! ”

"Let me try it first!"

While speaking, Li Daoyi took a step.

"Boom"!

When Li Daoyi stepped on the first nine-square grid, a sudden change occurred!

The passage where Wei Zede and the others came was blocked by a huge rock, and the flames on both sides of the passage where the "Nine Palace Diagrams" were located also turned a gloomy green.

"Am I on the wrong side?"

Li Daoyi stood on the bluestone slab, not daring to act rashly.

Wei Zede took out the ancient book again, and calculated it with his left hand according to the method recorded on it.

"Yi one yin and one yang, combined into fifteen, is the Tao. Yang becomes 9 out of 7, Yin becomes 6 out of 8, and it also coincides with 15 ...... The number of days is divided, with yang out, with yin in. The yang starts from the son, and the yin starts at noon, which is the ninth palace of the ether, starting from the Kan Palace......"

After hearing Wei Zede's calculations, Li Daoyi said in a deep voice: "It seems that the person who set up the formation here is also a master-level figure!" ”

"He used the 'Double Dragon Bead Throwing Array' as bait and the 'Transformation Nine Palace Diagram' as the base, and there was another strange array hidden here."

"This is going to kill them all! This person's longevity must be detrimental to ......"

"Comrade Li, Comrade Wei, don't think about what will happen to the people who set up the formation!"

Liu Rujiao said in a coquettish voice: "No matter how you research, this guy has been dead for thousands of years, so let's talk about how to break the formation?" ”

"What's the hurry!"

Wei Zede said indifferently: "If you can't guess the source of the strange array here, how can you break the formation?" One wrong step will inevitably leave no bones! ”

"That's right!"

Li Daoyi then analyzed: "From the layout here, it can be seen that this place is specifically for people like those who know a little bit about Xuanmen thaumaturgy!" If it's a half-ass, hum! Would definitely plant here......"

After some explanation, Wei Zede continued to calculate the steps to break the formation.

"This is the bottom of the abyss, and it must be based on 'earth' and 'yin'!"

"Qimen Dunjia is divided into four plates: heaven, earth, man, and god, and only the land is immovable among the four plates, which is to sit on the mountain...... Nine palaces, five element parameters, like a circular ......"

"In this case, we should go to the four Yin Palaces of 'Xun, Li, Kun, and Dui'!"

"Taoist!"

Wei Zede said to Li Daoyi: "My inference is for reference only...... What to do depends on your decision! ”

"Hey, hey!"

Li Dao smiled, "Compared to you, I don't even have a clue to break the formation...... Let's do as you say! ”

As he spoke, Li Daoyi calmed down and jumped towards the next bluestone slate.

"Whoosh!"

When Li Daoyi stood still, a sound of breaking the sky came from all directions.

"Oops!"

Wei Zede was shocked, and he hurriedly conjured a tarot card that had been prepared for a long time.

[Consumes 150 skill points, Transmog Card: Steel Shelter of the Wand. 】

"Bell, bell, bell!"

Appearing out of thin air, towering over the steel walls around Wei Zede and the others, a series of rapid crashing sounds sounded.

The steel wall lasted only a few seconds, and when it disappeared, Professor Liu Kai'an and Liu Ru were shocked by the dense array of arrows that sank into the cyan stone slabs.

"This ...... This ......"

Professor Liu Kai'an was dumbfounded and asked, "What happened just now?" ”

"Daoist! How are you? ”

Without bothering to answer Professor Liu's question, Wei Zede set his eyes on Li Daoyi, who was shot by an arrow next to his shoulder.

"I'm fine!"

Li Daoyi, who was covered with cold sweat, gritted his teeth and said, "Good Daoist, I have also practiced a few hands......"

After this crisis, Wei Zede and others smoothly passed through the three Yin Palaces of "Xun, Li, and Kun", and came to the "Middle Palace" located in the center of the passage.

"Whew!"

The tired Liu Kai'an father and daughter gasped for breath and asked, "What's the ...... here?" Why is there nothing? Call...... Are you sure...... Are you sure this is where the 'core of the agency' is located? ”

"That's right, this is it!"

Wei Zede, who was treating Li Daoyi's injuries, replied affirmatively.

"You two wait a minute......"

After Wei Zede bandaged Li Daoyi's wounds, he stood on the "Middle Palace" position and stomped heavily.

"Click, Click, Click......"

With the sound of the mechanism operating, a small stone platform slowly rises, and on top of this stone platform is a game of chess pieces.

"The chess game is seventeen vertically and horizontally, two hundred and eighty-nine ways!"

After seeing this chess game, Professor Liu Kai'an said: "This is the ancient Go game before the Wei and Jin dynasties, and it is different from the 19 Go that is popular now!" ”

"I can't think of it!"

Li Daoyi said with emotion: "This final mechanism will actually be an endgame......

"The people who laid it out are really painstaking!"

Wei Zede also nodded and said, "Most of the people who can arrive here are people who are proficient in metaphysics...... Where do they have the energy to study any more 'chess'? ”

This is one of the 'Seven Chapters of the Book of Qi' unearthed in Dunhuang...... Well, that's how it should go......"

Professor Liu Kai'an, who is proficient in chess, took out the black and white chess pieces from the stone box next to the chessboard, and played them while thinking.

After a while, after Professor Liu dropped the last sunspot, the sound of the mechanism operating sounded again, and a swarthy hole appeared above the heads of Wei Zede and the others.

"The exit is actually up there?"

Li Daoyi was surprised: "The people in this layout are really painstaking!" ”

Just as Wei Zede pondered how to go up, there was a slight vibration under his feet.

"What is this? Is it an elevator from ancient times? ”

In Liu Ru's incredulous low voice, the bluestone slab where Wei Zede and the others were standing slowly rose and moved closer to the hole that appeared above.
