After walking for about ten minutes, the straight wall changed, and there was a turn of more than 90 degrees in the oblique stab.

Between the two passages, an obtuse angle is formed, and on the opposite side of the obtuse angle, there is an additional arch, the internal test of the arch, a round room reason, something similar to an incense burner is placed in it, three legs, three ears, there is a pattern on it, judging from the shape of the utensils, it looks like something from the Sixteen Kingdoms, looking at the material, it is no longer bronze, it is iron, or, a kind of pitch-black, unknown iron.

Many modern people don't know, in fact, the ancients had a high understanding of alloy technology, in the past, often seen large metal objects, alloy accounted for more than half, estimated, this thing, can also be regarded as a masterpiece.

I walked over to take a look, the tripod, how tall can there be a person, the relief on it, very abstract, like words and not words, made me a little messy, in the mouth of the tripod, and the position of the foot, some details have been carefully handled, from this point of view, this thing, it is really possible to have something to do with the ruling class at that time.

Thinking of this, I didn't pay much attention to it, jumped up and took the tripod and looked inside, there, there were some, like firewood black charcoal, I was more curious, so I grabbed a handful very much, crushed the things in my hand and looked carefully with a flashlight, and felt that the whole person was no longer beautiful.

What is in there is a bone, which has been scorched and has become a bone similar to a charcoal fire, Maoshan, which was made by burning a living person when some strange ceremony was held, which is a bit disgusting, but it is more real.

Out of all these considerations, I didn't tell Ding Ling and Xiaopang the truth, clapped my hands to get those things off, and followed them back along the next section of the passage to the inside, walked a few steps, stopped, a spiritual light flashed through my mind, I quickly ran back, and looked at the angle formed by these two straights

This angle is a bit special.

After thinking about it for a while, I asked Ding Ling and Xiaopang to help, and used a red rope to extend the straight line formed by the passage, and formed an angle between the new wall and the straight line sandwiched from the ground, and very carefully and carefully made three perpendicular lines to the red rope where the red rope was sitting, and at that time, three isosceles right triangles of different sizes appeared under the beam of the flashlight

According to the sum theorem of internal angles, the sum of the three angles in the triangle is 180 degrees, and the right angle that we deliberately made is 90 degrees, and then two bottom angles of exactly the same size can be obtained, and the complementary angle of the angle between the two channels is 18 minus 90 and then divided by two, that is, 45 degrees, from this point of view, the angle formed by the two channels is 135 degrees, one point is not much, one point is not much.

One hundred and thirty-five degrees is a very important angle, as far as I know, each inner angle of the Bagua shape is an angle of one hundred and thirty-five degrees, if this angle is not a coincidence, it means that this underground palace is very likely to be a fairly regular octagonal shape, and the whole is a gossip.

Thinking in his heart, he seemed to understand something, and trotted over with a flashlight, and sure enough, in front of him, he met a corner exactly the same as before, and on the opposite side of this corner, there was also a round room exactly like the one he had just seen, and a black tripod more than one person high.

Chubby has encountered a few ghosts hitting the wall, and when he saw this situation, he was furious, I told him not to panic, and turned out a pen and paper in his backpack to draw a simple schematic diagram, which is calculated, and it is understood.

At the beginning of the passage we entered, we came up clockwise, passing by two angles, each of which had a similar tripod, and each angle was one hundred and thirty-five degrees like a scene, which showed that this was really a bagua-shaped structure.

One of the Bagua-shaped walls was empty, and there was no passage like the one we walked through when we came, which means that, unlike the tall black ding, the straight passage to this Bagua is not eight, but four, or two, and according to my understanding of the ancient Qimen phalanx, four is more likely.

Because, in fact, these four channels are to cut the eight tripods into four small parts that are divided into two and two, which coincides, and in the theory of yin and yang, the four elephants are divided into eight trigrams.

Thinking of this, I came to the spirit at that time, and simply told the little fat and them what I thought, and I didn't care about explaining carefully like two guys in the clouds, so I pulled them to chirp and run forward, stopped breathlessly, and suddenly brightened up in front of us, because, in front of us, the passage that was exactly the same as the one when we came in, was lying gorgeously in front of us!

"Oh, what does that mean? Boss, are we going to encounter a ghost hitting the wall again? There is a deep resentment for this infinite loop of landscape, Chubby grinned.

"Don't talk nonsense, it's not a ghost hitting the wall, it's another way." As I spoke, I hurriedly looked around with a flashlight, and when I turned my head, I saw that in the same position as the stone gate I pushed last time, a big black hole, was standing quietly on the pile of rubble, yes, this is it, sure enough, someone has been here.

Thinking of this, I hurriedly pulled Ding Ling and the others to run over there, a kind of throbbing that was about to find the treasure spontaneously, but, when I ran over to take a look, I was speechless, looking at it from a distance, I didn't feel anything, I really got closer, only to find that there were many corpses lying at the door that I don't know how long.

One by one, all that was left with tattered clothes and gray-black bones, a kind of thing, I don't know if it was hair, was scattered among the corpses, and before the people passed, the wind was blowing, and the sound of ghosts crying and howling wolves was faintly visible.

In this kind of underground palace, there will definitely not be such a strong air flow, and even if we have been in battle for a long time, we realize that we are in danger at the same time, I don't need to say, Xiao Fat pulled out his peach wood sword and formed a corner with me, protecting Ding Ling behind him, but the faint voice was still wrapped in the yin wind, and he refused to leave for a long time

"What is this?" Grabbing my clothes nervously, Ding Ling asked me weakly.

"I don't know, it should be, when I come, the soul of the dead who died under the random arrows." I said, exhaling a long time.
