?

  My thoughts were suddenly drawn to it, my eyes fixed intently on the black donkey hoof that Old Six was holding in his hand. This thing was originally hard to burn, but because oil had been poured on it, a faint flame emerged, with a layer of blue light enveloping its surface, which was a normal reaction when oil was added, and I didn't think much of it.

  Lao Liu held the iron tongs of the smokeless stove in his hand, clamped the hooves, and then raised them high to illuminate. As he looked around the tomb path, I thought that if we really ran into a hard dumpling, it would be dispersed by the black donkey's hoof shining with Tongzi blood. So I said to everyone, "Let's continue moving forward."

  That fatty's surname is Jin, I only heard people call him Jin Er Bao, guessing he was the second child in his family. Jin Er Bao replaced that quickly burning out candle with a new white wax one and said: "After walking through this tomb passage, it's two-thirds of the time, hopefully we won't see this candle again."

  Then we continued to move forward, Lao Lei carrying me on his back. He was sweating profusely, and I felt uneasy about it, so I asked him to put me down. Lao Lei didn't say a word, but looked at Er Shu, waiting for his nod before putting me down.

  I find it strange that this Black-Faced God is as loyal to Second Uncle as Pan Zi was to Third Uncle. I can understand why Pan Zi would be grateful to Third Uncle, but what has Second Uncle ever done for the Black-Faced God to deserve such devotion?

  I followed at the end, leaning against the wall and walking behind, looking at the row of people in front. Among them, a woman was called Minmin by others, which reminded me of Jin Yong's "The Heaven Sword and Dragon Saber". I don't know if this Minmin is as clever as that one. Anyway, she didn't talk much along the way. To be honest, there aren't many women with such low profiles, but since Second Uncle brought her along, she must have some skills.

  That guy called Lao Liu should be an old fighter, judging from the fact that he always has a gun with him and is highly vigilant. Second Uncle invited him to join the fight, I reckon it'll cost a lot of votes. Another one is Jin Er Pao, who isn't really fat, just slightly plumper than ordinary people, but I don't know how he got this nickname.

  Judging from the current situation, it seems that Ershu and his group entered the tomb passage, which is obviously not the same route as mine. Then who blew open that grave door? Ah Ning? If it was them, why would they appear in the burial pit?

  I don't think it's likely to be An Ning's person, just thinking about it, a person suddenly appeared in my mind - Third Uncle! Could it be Third Uncle?

  Three Uncle arrived at Kunlun Mountain a year ago, so is it possible that he has been here? Also, the evil character in the Mao Ball Tunnel was neither written by Second Uncle nor Fatso, so the most likely person is Three Uncle. He's like a bottle of oil, leaving clues everywhere he goes, but strangely, Three Uncle clearly didn't want me to come to Kunlun Mountain, so why did he write the evil character?

  Does this evil word have any other meaning besides hinting at me?

  I ran to the end of the ghost road at that time, and then entered the tomb passage. Is it possible that Third Uncle also came in? Which tomb passage did he enter? What is the relationship between the several branches in the ghost road, and what's behind those branches?

  Just as I limped forward, Jin Erbao's voice came again, this time with a very bad tone, almost scolding, and the scolding was quite vulgar: "Damn it, Xiong is back, what kind of ghost-blowing lamp, damn it." He scolded too loudly, Minmin frowned and said: "Jin, calm down."

  After I finished speaking, no one paid attention to me. It was clear that I had miscalculated twice and these people had already excluded me from their circle. At this time, it was actually my second uncle who looked over and said, "Sit down and rest, you really want to be a cripple!" I quickly sat down with a thud. Probably because my obedient appearance was too ridiculous, Minmin burst out laughing, and the atmosphere suddenly wasn't so awkward anymore.

  I sat against the wall, thinking about my current situation. If it wasn't because of the zongzi, then could it be due to a mechanism? The mechanism in the underwater tomb's wall is still vivid in my memory. Could there be a similar mechanism here? When the mechanism operates, the tomb passage will silently change, causing us to keep circling around the same spot?

  I hesitated before speaking, and had only gotten halfway through when Minmin furrowed her slender eyebrows and said, "A mechanism? One that's so formidable? Do you think this is a Rubik's Cube?" I thought to myself: This is nothing, there are many more where that came from, but she's just a girl, I couldn't say something like that out loud. At least in this tomb passage, it's relatively safe, but if we were at the underwater tomb and encountered that mechanism wall, our whole group would have been turned into meat patties by now.

  I didn't bother to respond to Minmin and continued, "If it's a mechanism, we can approach it from two aspects. Judging from the time period of this tomb, it should be from the Western Zhou or later. At that time, the technology of mechanisms was not advanced, unlike the late Ming dynasty when the art of mechanisms had developed to the stage of internal concealment. All mechanisms before Qin could find external triggers, so our first point is to look for the trigger. Second, you've been in this tomb passage for a whole week, if there's any mechanism inside, you should have discovered it by now, but since you haven't found anything yet, there can only be one reason - the trigger is extremely well-hidden, in places that are invisible to the naked eye."

  I finished speaking and found that Old Six nodded, with a hint of appreciation in his eyes. I couldn't help but feel secretly pleased. People like us who deal with antiques have some knowledge of these esoteric things, but after the Lu Wang Palace incident, I deeply felt my lack of professional knowledge and made up for it by studying hard. Now I can finally say that I haven't wasted my time.

  Speaking of which, I couldn't help but think of the two fingers of the oil bottle, that invincible hairpin finger, if it were here, even if the mechanism was hidden in heaven, he could still turn it over.

  Second Uncle seemed to be thinking of something, and suddenly said: "There are too many places that can't be seen with the naked eye." I understood what Second Uncle meant. The internal mechanisms in the tomb passage have many hidden triggers behind the tombstones. This tomb passage takes about 40 minutes to walk around, from top to bottom, from left to right, and there are countless tombstones. Do we really need to dig out each one?

  At this time, Old Six shook his head and said, "It's not a mechanism." He was clearly the leader of the group in the fight, and as soon as he spoke, everyone turned their eyes to him. Old Six looked at me and said, "The mechanical techniques in ancient tombs are varied and strange, but they can be divided into two types. One type is a one-time mechanism, such as crossbows, which tomb raiders trigger once and then cannot be activated again. The other type is a repetitive mechanism, such as the common flip board in ancient tombs, which can be triggered countless times, but only this small mechanism can achieve this level. What you said about the tomb passage being an operational mechanism is unlikely, the project is too grand, and the time was before and after the Western Zhou Dynasty, at that time there was no technology to create a large repetitive mechanism." Although Old Six's eyes had a hint of appreciation, he still rejected my statement.

  I thought about it and found that what he said was right, including the mechanism of the underwater tomb of Wang Zang Hai, although it is strange and peculiar, but it is also a one-time mechanism, which will not be reopened after being closed. Thinking this way, if a grave passage mechanism operates continuously for thousands of years, it's obviously unrealistic.

  As soon as I thought of this, I suddenly felt my face burning, and silently lamented that I was indeed too tender. All three ideas were rejected. In the past, when I encountered such a situation, it was either a mechanism or a ghost hitting the wall. I had experience, so I wasn't panicked now. But after Old Six said this, it turned out that both of them were excluded. So, it means that what made us appear in this situation is something unknown to me too.

  As soon as I thought of this, my relaxed heart suddenly tensed up. Second Uncle saw me like this and heavily snorted, saying: "No guts, what's there to panic about!" This whole time, it was either being beaten by Second Uncle or scolded by him, still in front of so many people. For a moment, I wanted to find a crack in the ground to crawl into. Moreover, having said the wrong thing three times and wasting everyone's effort, I felt like I had no face left. This time, I really didn't dare speak again.

  I obediently lowered my head, and others had nothing to say either. After this ordeal, it was almost four hours later. The atmosphere of the group was silent. Finally, Minmin spoke up first, but as soon as she opened her mouth, I suddenly felt a thrill all over my body.

  Min said: "Could it be Qimen Dunjia?"

  It was this sentence that suddenly enlightened me, I majored in architecture, and when I was in college, there was an elective course with a very short class time, only five or six sessions, called: Strange Construction and Thinking.

  In class, the teacher took out a triangle.

  As soon as that triangle was taken out, all the classmates exclaimed in surprise, because it can be seen with the naked eye that this triangle belongs to an impossible triangle.

  This triangle has a total of four sides, but no matter which angle you look at it from, you can only see three sides. The extra side that appears plays a magical role, making a flat triangle produce a 3D effect and creating a huge visual impact.

  At that time, the teacher said that this triangle was designed by a German in modern times and is known as one of the buildings that cannot appear in the world. However, if you master its method, you can easily make it.

  The method is to find the connection point of the fourth side with the other three sides.

  I don't understand what Qimen Dunjia is, but after listening to Mingming's words, I suddenly had an idea. Are we in a situation like this? Suppose this tomb passage, neither ghost wall nor mechanism, from start to finish only 40 minutes journey, then the reason why we can never get out, will it be that there is also a fourth side here?

  The more I think about it, the more I feel that my idea is feasible. However, after the previous three mistakes, almost no one has given me a second glance. I thought for half a day and still felt that I should give it a try. I mentally prepared myself: if I fail, so be it; living isn't just about saving face.

  Then I interrupted Minmin's discussion about Qimen Dunjia, and expressed my own thoughts. I don't know if it was because of my poor expression or other issues, but the others all had a look of seeming to understand yet not understanding.

  I also expressed understanding, because when I first saw that quadrilateral triangle, I couldn't understand it either. Moreover, they had never seen that triangle before, and based on my oral description, they couldn't understand it even more.

  I finished speaking, and Jin Er Pao said: "Young Master Wu, what do you mean by that? I don't understand what you're saying."

  I could only smile wryly and spread my hands, saying: "This is just an idea of mine. To prove it, I can only use actual actions. I can't guarantee success, but I hope to give it a try."
