Qingming Cave is relatively straight, but unlike the other caves, its path is down, and it is extremely narrow, allowing only one person to pass sideways. The hole is not high, only one and a half people, barely walking a hundred steps, under the faint firelight, you can see that there are nine round bluestones of different sizes in front of you, arranged in a strange pattern, some are raised, some are sinking, and there is a murderous intention hidden in the chaos.

"In the rain cave before, I have seen a similar kind of bluestone, follow Wei Chang'an's footsteps and write down how to walk, but the formation of the two caves may not be the same, according to the script, it is sloppy ......"

Qingming put Yin Changsheng on the ground, slowly leaned down, pondered for a moment, got up and said: "This is a game of Yang escape, heaven six, earth seven, yin three, and four, the birth gate is at the threshold, Lang Jun settles with me!" ”

"Good!"

Qingming sandwiched Yin Changsheng under the flank, first starting from the third bluestone on the left, then the seventh on the right, then the sixth in front, and finally the fourth from the bottom, and landed gently.

Qingshi lay there quietly, without any reaction!

Xu You drew a scoop according to the gourd, and the last piece was more powerful when it landed because of the distance, and with a bang, the bluestone actually sank down three inches. There was a squeaky sound in the ears, as if the blade of the knife cut through the iron plate, which made people upset and irritable, and the surrounding mountain walls fell dust and gravel one after another, revealing dozens of deep holes as if by magic, only the thickness of the thumb, and if you look closely, you can see the cold luster of the metal.

Qingming was quick-eyed, grabbed Xu You and pulled him behind him, threw himself to the ground, and put the poor Yin Great Sacrifice Wine on the backs of the two of them as a meat shield, just in case.

Sou! Sou! Sou!

The short and rapid arrows instantly sealed the entire bluestone area, intertwined like a net, impermeable, if someone was still on the bluestone and did not react, this would have been shot into a porcupine with the most thorns.

After ten breaths, the sharp arrow whistle stopped, Xu You turned over and sat up, exhaled a long breath, and felt really good for the rest of his life, and said with a smile: "Thanks to you...... Otherwise, if you don't succeed, you will die in this vicious trap......"

"It's because I didn't think it through, I should have borrowed Lang Jun's strength just now!" Qingming is telling the truth, there is a big difference between people who practice martial arts and ordinary people, he is very light, and the weight of stepping on a stone is almost equal to a feather, but Xu You is different, the turbidity is in the chest, the breath sinks, and when you step up, the stone will inevitably move.

"It's not your fault, I should have thought that this last bluestone was so far away from the other stones that it tempting to jump over it with all your might, there must be a trap...... Still careless! ”

Xu You looked at the iron arrows densely pierced into the rocks of the mountain wall, you can imagine how strong it is, how sharp the arrows are, the mechanism behind the mountain wall should be the dark crossbow that has been used in the mausoleum a lot since the Spring and Autumn Period, according to legend, in addition to a large amount of mercury in the mausoleum of Qin Shi Huang, the most is this kind of dark crossbow with huge lethality, but I don't know how to design it. Judging from Fang Cai's situation, as long as he is sure that he can trap people in a small space, I am afraid that even the little grandmaster will be unable to escape.

After a short period of recuperation, the two continued to descend, and after walking dozens of steps, three holes suddenly appeared in front of them, leading to three different roads. In view of Fang Cai's danger, it can almost be concluded that only one is safe, Xu You turned his head to look at Qingming, Qingming smiled: "This is simple, fight to point B, Qingming to." Since it is Qingming Cave, the second position is in the earthquake ......"

Xu You took over and said: "There are eight gates in the sky to pass through the eight winds, and there are eight directions on the earth to respond to the gossip." Gossip, heaven and earth positioning, mountains and rivers are ventilated, thunder and wind are thin, water and fire do not shoot each other......"

Qingming nodded and said: "The positioning of heaven and earth is Qian, Kun, the ventilation of the mountains is Gen and Dui, the thunder and wind are thin and the earthquake and Xun, and the water and fire are naturally difficult and separate." The earthquake is a thunderous hexagram, located in the east, the Lord is not chaotic, and enjoys unobstructed access," he pointed to the road due east, and said, "Go here!" ”

After speaking, he was just about to take a step, Xu You grabbed his arm, Qingming turned around in surprise, and said, "Lang Jun? ”

"How many stones are there in that bluestone henge?"

"Nine!"

Xu You said in a deep voice: "You use King Wen's gossip to deduce the earthquake position, and add the number of hexagrams up and down, left and right to add it to geometry?" ”

Knowing what Xu You meant, Qingming's face became solemn and said, "Ten! ”

"Not bad!" Xu You said: "I am far inferior to you in terms of easy counting, but if you want to estimate people's hearts, you are inferior to me." Although I don't know who set up the formation of these 24 holes, but looking at the grandeur of its pattern, every step has a deep meaning, and it is impossible to set up the bluestone formation for no reason...... So I guess these three paths are not deduced from the gossip of King Wen, but based on the gossip of Fuxi......"

Fuxi is an innate gossip, and the symmetrical number of hexagrams adds up to nine. King Wen is the acquired gossip, and the symmetrical hexagram numbers add up to ten. Qingming almost broke out in a cold sweat and said, "What Lang Jun said is extremely true, I was careless again!" ”

"It's not that you're careless, but the people who set up the formation are too vicious, Bluestone Formation is a game of Yang Escape, but anyone who knows the eighteen games of Yin and Yang can easily break it. After success, you will think that the following formations are also in the deduction of King Wen's gossip, so you will fall into a pre-set trap, this is the terrible thing about inertial thinking! ”

Qingming didn't understand what inertial thinking was, but he understood the meaning of Xu You's words, and said: "The epicenter of Fuxi gossip is in the northeast, then, we want to go to the northeast?" ”

Xu You immediately made a decision and said, "Take a gamble!" Walk! ”

He was about to enter the cave, but Qingming took the first step and said, "I'll come, Lang Jun wait!" "Walking five steps in a row with Yin Changsheng on his back, there is no abnormality, it seems that he is right. Xu You followed in, the fire fold in his hand could only shine three feet around, but at least it was safe, and said with a smile: "I'm a little curious now, what are the vicious traps on those two roads?" ”

Qingming said: "This trap is actually not evil, the previous bluestone henge launched the machine bracket set up in the last stone, if it is set in the middle, wouldn't it be better?" And it has a sound warning first, and then a falling stone warning, as long as you don't panic, you can jump out and dodge those deadly arrows. When I look at this array, there is room everywhere, and there is a way to survive in the dead end, which should be different from those traps that only take people's lives. ”

Xu You showed appreciative eyes and exclaimed: "What you said makes a lot of sense, think about it carefully, after all, Heming Mountain is a place for cultivating and seeking truth, and the strange array in the belly of this mountain may not be set up to kill people, but only for testing, only those who are wise and brave can enter the heart of the heart......

As he spoke, the road under his feet began to become straight, originally obliquely down, but now it became horizontal, and after more than 20 steps, the road in front of him came to an end.

Qingming touched the thick mountain wall, knocked it a few times, and then let the true qi penetrate, and said in a low voice: "It's not a dark wall, there is no road behind!" ”

Xu You also stepped forward to listen to the meeting, tapped his fingers lightly, and muttered: "Could it be that being smart is mistaken by being smart, in fact, it should be the road that King Wen gossip is the first to the east?" ”

Saying that, looking up, there was not the slightest gap in the rugged cave roof, and the depressed person was out of breath, Xu You's heart moved: "In the Fuxi gossip, everything turns from yin to yang in the Qingming solar term, and when you meet the door of death, you will find a way to survive from the yin soil......"

The two of them bowed their heads at the same time, Qingming squatted on the ground carefully, his palm was attached to the hard ground to input true qi, and after three breaths, he heard the metal echo of the buzzing sound, and without Xu You's command, he slid out a short dagger from his sleeve, and entered the soil like cutting tofu, and quickly cleared out the secret door under the ground.

This is a Taiji diagram bronze door composed of yin and yang fish, the eyes of the two fish hang a thick copper ring with a bowl mouth, and an openwork exquisite scroll-style iron lock firmly locks the copper door. The ends of the locks are decorated with lion heads and tiger faces, and the scrolls have eight rotatable gilt rings, each engraved with nine oddly shaped characters, small and scrawled to make them illegible.

"This is Zhong Dingwen, I don't know much, I only know five of them. But there are a total of seventy-two characters on this scroll, and eight characters need to be selected and connected with the carved pattern of the lock. These eight characters are either verses or from classics, and only if you answer them correctly, you can unlock the door. If it's wrong......" Qingming smiled bitterly: "Think about the bluestone henge with a dark crossbow into a net, we are blocked in this dead end, I'm afraid we won't be able to hide." ”

Xu You had read Mr. Rong Geng's "Jin Wen Compilation" in his previous life, which gathered 3,722 Zhong Ding characters, and the ones that could be identified were about 2,420. I have to say that the person who made this lock is full of bad taste, and Zhong Dingwen has completely withdrawn from the circulation field since the Shang Zhou Dynasty to the Qin Dynasty. In ancient times, there were very few people who read and wrote, and those who studied this were even rarer, and it can be said that there was no one in ten thousand. It is difficult to use Zhong Dingwen as a password, but it is deliberately written in cursive, the strokes are messy, and the crooked image seems to be a combination of pictograms and understandings, which is even more difficult.

Think about the vast sea of the hundred schools of thought of the classic anthology, any obscure words, any cold poems may be the mystery of this lock, if not the two of them are well-read, well-learned, and facing an inescapable life and death crisis, in fact, they can give up completely.

Xu You barely recognized the third gilt copper ring, and felt that his eyes were about to be blind, and tears were hidden in his eyes, and he didn't need to look in the mirror to know that he was covered with bloodshots.

"It's not going to work, it's not good for us to delay it too long. I don't know how many mechanisms there are below, so we have to solve them quickly! Xu You asked Qingming to take out all the fire folds in the dark bag, and ignite five at the same time, illuminating the yin and yang fish copper door clearly and brightly, no longer looking at the back five copper rings, only looking for clues that can form verses or classic sentences in the first three copper rings, repeated more than fifty times, he finally found a clue.

"The first one has the word grain, the second has the word god, and the third has the word no...... Qingming, you say, what should the first four words be? ”

Qingming immediately understood, his eyes shone slightly, and said, "The god of Ceres is immortal......

"Exactly!" Xu You let out a breath of turbidity easily, a smile appeared on his face, and said, "The god of grains is immortal!" I'll make a bet with you, the last four words must be 'Xuan's Gate'! ”

Qingming said with a cold face: "I haven't received the money last month, and I know that I will lose and gamble, that's a fool, not to mention that I can't afford to lose Lang Jun!" ”

Xu You almost laughed, but fortunately remembered that this was in the cave, so he could only hold back the strange laughter of eating, and said, "Don't worry, the money is indispensable for you." If you don't learn it, follow the sting to learn these problems! ”

The two of them are arguing in order to relieve the tension that has been being strained, and to relax to a certain extent, so that the attention will not be busy and make mistakes in the case of high concentration.

Laughing and laughing, I have found the word Xuan from the fourth copper ring, and with a conclusion, it will be much easier to deliberately find it, and then the words 牝, zhi, and door have also been found.

The god of grains is immortal, the gate of Xuanjiao!

This is the words in the "Tao Te Ching", and it is explained in the "Wu Zhen Zhizhi": The movement of the god of grains, that is, the gate of Xuanjiao. This door is in the human body for the four major places, in the middle of the heaven and earth, a hole is hung in the void, opening and closing sometimes, the movement is natural, the number is called the entrance of a trick, and the number is called the door of all wonders.

The gate of all wonders is the root of all things in heaven and earth, and the source and end of the Tao!

Xu You turned the copper ring, starting from the word "Gu", one by one to the word "Zhi", then stopped his hand, held the last copper ring, and said: "I have a hunch, under this Yin Yang Fish Gate, it should be the place we are looking for!" ”

Qingming condensed and held his breath, in case there was another hidden weapon. However, according to Fang Cai's guess, there will always be a way to survive in the formation, such as the Yin Yang Fish Gate is so difficult to crack, but the mystery is actually very simple, everyone who has read the "Tao Te Ching" knows this sentence, which is neither obscure nor unpopular.

However, this is an afterthought, without calmness in the crisis, without the accumulation and application of knowledge, it is undoubtedly a fool's dream to unlock the iron lock in such a short time.

Squeak!

The copper ring rotated slowly, the word "door" from the bottom to the top, and gradually came to the horizontal line in the center, with a click, the lock cylinder was aligned with the concave and convex inner shaft, Xu You pulled out a long lock pin, and bang, the copper door visibly vibrated with the naked eye.

"Lang Jun, I'll open it!"

Qingming grabbed the copper ring with both hands and pressed it up, and suddenly his feet were empty, the entire ground collapsed, and the three of them fell down at the same time.

It turns out that this yin-yang fish bronze door is just a bait, and the real trap is to kill people in an invisible chain flipper!
