Zhou De said: "Have you been stopping here? Did you go down? ”

Qiu Tian said: "We climbed down for a long time, until we reached the end, and when we saw that there was no bottom, we climbed up again. ”

Nanyang said: "What, you also found something wrong?" ”

Gao Qin said: "We climbed down at the beginning, it was normal, and then after a period of time full of statues and ancient talismans, the surrounding environment seemed to change suddenly, no matter how we climbed down, there seemed to be no end, fortunately I met you, and everyone got together again." ”

Nanyang pondered for a moment and said, "Our experience is the same, we should have reached the bottom of the cave, but for some reason we arrived at this place, it seems that there is indeed a mechanism here." ”

Xu Ming said nervously: "How can there be such a large space in this place?" It seems to be an abyss leading to the center of the earth, how can there be such a place in the ancient ruins? And, how did we get to this place? The rope has always been vertically downward, and we have only been crawling in this direction without changing direction. ”

The pillar said, "No, even if we reach such a deep place, we can't go down to the end, and we can't climb up and up, but the rope we have at hand will never be so long, I have a count of the length of our rope." ”

Everyone thinks so, even if everyone is deceived into going astray, but the length of the rope is fixed, can someone extend the rope infinitely? It's amazing.

Everyone thought for a while, but still couldn't figure it out, everyone came down from the hole under the stone plate, passed through a section of the stone wall carved with ancient rune wall carvings, and arrived at this place, was it really transferred to another space by the magic of the ancients?

Nanyang and the others checked the surrounding stone walls and found nothing special, Nanyang said: "Let's climb up first, if we can go back to the original place, study it carefully, and then come down." ”

Everyone climbed up along the rope together, and climbed for dozens of minutes, but they didn't see any signs of rising, everyone was very tired, and the mood was also very depressed and nervous, originally thought that they were about to arrive at Liu Sheng's burial, but there was such a strange thing. Everyone reluctantly drank some water and rested for a while, Xu Ming gasped and said nervously: "Hell, it didn't take us so long when we came down, why can't we go back now?" ”

The pillar said: "If we hang here all the time, even if we don't fall to death, sooner or later we will starve to death and die of thirst, what kind of place is this?" If you can get in, you can't get out. ”

Zhou De was already tired and panting, and was frowning and thinking about what the situation was here, when he heard what the pillar said, his face immediately changed, and he said nervously: "I know." ”

Nanyang asked, "Master Zhou, what is the mechanism in this cave?" Everyone listened nervously to Master Zhou's talk about what strange arrangements were in the cave.

Zhou De said: "We encountered a situation similar to 'ghosts hitting the wall', this cave is actually not such a large area, but we ourselves are confused. But it's not just as simple as 'ghosts hitting the wall', it's likely to be a more complex structure like Qimen Dunjia. ”

Nanyang, Xu Ming and others are of course familiar with superstitious sayings such as "ghosts hitting the wall" that are circulated among the people, but they don't believe it, and they have never encountered it, but they didn't expect to encounter it in this place and at this time.

Qiu Tian asked curiously: "Master Zhou, what is 'Ghost Hitting the Wall' and 'Qimen Dunjia'?" ”

Xu Ming was a little surprised, and said disdainfully: "Researcher Qiu, you haven't even heard of 'Ghost Hitting the Wall' and 'Qimen Dunjia'?" Are you really from the Celestial Empire? ”

Qiu Tian smiled and said, "I'm sorry, I live abroad most of the time, and I don't know much about these customs and legends in China. ”

Xu Ming said: "'Ghost hitting the wall' refers to people walking at night or in the suburbs, being confused by ghosts, constantly circling in a circle, and unable to get out. This phenomenon is first and foremost real, and many people have experienced it. He went on to say: "There is no such thing as a 'ghost hitting the wall' caused by the real confusion of the 'ghost', and this phenomenon has nothing to do with the ghost or god, but can be explained by science." ”

Gao Qin said: "The emergence of this phenomenon has a great relationship with biology. Do a common simple experiment by blindfolding a mallard and then releasing it, and if there is a wide space, you will find that the mallard must fly out in a circle. Of course, you can also use people to experiment, blindfold people, walk in a straight line according to your own feelings on the school playground, and the final walk will definitely be a big circle. In a word, the essence of biological motion is circular motion. ”

Gao Qin continued: "If there is no goal, the instinctive movement of any creature is a circle, because there are subtle differences in the body structure of living things, and the limbs are not completely symmetrical, for example, there are subtle differences in the strength and muscular development of the two wings of birds, and there are also differences in the length and strength of the two legs of people, so the distance of the steps taken in this way will be different, if the distance of the left leg is slightly longer, and the distance of the right leg is slightly shorter, so that the accumulation will definitely be a big circle, and the same is true for other creatures." ”

At this time, Xu Ming said: "But why can living things keep moving in a straight line, for example, why do people walk out of a straight line?" Because we can use our eyes to constantly correct the direction, that is, to use the brain to locate and correct, so we walk in a straight line. If the work of the eyes and brain fails, the phenomenon of 'ghosts hitting the wall' will appear, and at this time the person will definitely lose his sense of direction, that is, he will be lost. When the correction function of the human eye and brain is wrong, or the correction signal given by the surrounding environment is false and chaotic, although the person feels that he is walking in a straight line, he has actually been confused by himself, and it must be a circle when he comes out, and the cycle does not stop. ”

"Therefore, in special environments, people are prone to confusion about the signals around them, because people recognize the signs whose direction is mainly on the ground, but these signs sometimes create false impressions and give people wrong information. Since ancient times, legend has it that many masters have mastered this scientific secret called 'alien art', and when they build buildings, they will artificially arrange some ground markers, showing a lot of false information, which confuses people's judgment, and it is easy to get lost, and feel that they have encountered a ghost hitting the wall. ”

Nanyang said: "No, there is a problem in saying this, we climbed down the hole in the ground, although we also saw the environment here with our eyes, but mainly by ropes to descend. Because of gravity, the rope is vertical, and people can be deceived by the environment here, but the rope is impossible to be deceived, so we have been climbing straight up and down, and we won't go around in any circles here. He continued: "Moreover, the length of the rope is fixed, and how it can become endless, is not just a matter of human error." ”

After listening to what Nanyang said, everyone thought that if there was some kind of factor in this cave that Xu Ming said that would affect people's judgment, it must not affect the rope, let alone extend the rope indefinitely.

Zhou De's expression was grim, and he said: "That's why I said that this place is not just as simple as 'ghosts hitting the wall', I'm afraid it will be a more powerful layout like Qimen Dunjia." ”

Qiu Tian said: "What is 'Qimen Dunjia'? ”

Zhou De said: "According to the records in ancient books, Qimen Dunjia originated more than 4,600 years ago, when Xuanyuan Yellow Emperor fought Chiyou, Chiyou was seven feet tall, invulnerable to iron head and bronze body, and would call for wind and rain, create fog on the battlefield, and make the Yellow Emperor's troops disoriented. The Yellow Emperor fought hard and could not win, so he set up a fast under the Taishan Mountain, and the Queen Mother of the West sent an envoy to give it a charm, and told him to pray for heaven with contemplation, and there will be the induction of Taishang. A few days later, the Nine Heavens Xuannu took the Danfeng, the Yujinglong, wearing the clothes of the nine-colored emerald, descended on the Yellow Emperor's Zhai, and awarded the Yellow Emperor Liujia Liuren Soldier Letter Talisman, the Heavenly Seal Book Dragon Armor Divine Medal, and the Sword of the Ten Peerless Spirit Flags of the Nine Light Jade Festival. According to the contents recorded in the book, the Yellow Emperor created a guide car and finally defeated Chiyou. In addition to recording the method of building weapons, the Dragon Armor Divine Chapter also records a lot of mystical techniques of the five elements of yin and yang, as well as the art of war of sending troops to fight wars. The Yellow Emperor ordered his prime minister, Empress Feng, to interpret the Dragon Armor Divine Chapter into thirteen chapters of the Art of War, twelve chapters of the Lonely Void Law, and one thousand and eighty rounds of Qimen Dunjia.

Later, after Jiang Taigong of the Zhou Dynasty and the old man of Huangshi in the Han Dynasty, it was passed on to Zhang Liang, who streamlined it and turned it into the Qimen Dunjia that has been handed down now. He went on to say: "The number of techniques in Qimen Dunjia is incredible, unfathomable, legend has it that Zhuge Liang is good at Qimen Dunjia and the five elements of yin and yang, and the method of Zhou Yi, creating eight arrays, there is a story that once placed a stone formation in Yubeipu, and besieged Lu Xun, the general of Eastern Wu, in it without getting it. These ancient thaumaturgy are far from being comparable to simple things like 'ghosts hitting the wall', and I'm afraid that what we encounter most now is such a layout. ”

Nanyang didn't believe these at all, and asked questioningly: "Could it be that these ancient legendary spells really have such powerful mana?" Can you extend the rope indefinitely? Or even stretch space-time? ”

Zhou De said: "This is not necessarily distorting the space, but it closes us off and enters a continuous cycle of bureaus, perhaps it makes us have illusions all the time." ”

Qiu Tian thought for a while and said, "I understand, is it so understanding, we are hypnotized." ”
