"I see, this time the official wants to take the test for this ......" After Xiaolu mentioned it, Yang Yunyi suddenly realized, but he was also the same as Xiaolu, he didn't show much surprise, and among the three, only Ye Yu was a little dumbfounded.

"Qimen Dunjia? Do you mean...... The one in metaphysics?? Ye Yu asked nervously.

"Many people do regard 'Qimen Dunjia' as a kind of divination, so it is rumored to be mysterious, but it is essentially a high-level astrophysics, including our nation's philosophical wisdom, calendar, cosmic social outlook, astronomical knowledge, war, strategy, and so on." Yang Yunyi explained.

"'Qi' refers to the three odds, namely B, C, and D; The door refers to the eight gates, namely "opening, resting, life, injury, Du, scenery, death, and shock"; "Dunjia" refers to the first escape into the six instruments in Liujia, that is, "E, Ji, Geng, Xin, Ren, and Gui". In ancient times, "Qimen Dunjia" was used in warfare, which could play a role in winning a hundred battles, so it was also a compulsory course for all people in the military system. ”

"It feels so profound...... It's a pity that mortals like me don't understand it. Ye Yu spread his hands and said with a wry smile. All you have to do is explain to me a little bit what the situation is. ”

"The situation is that we have to use the large compass in front of us to calculate the way out, otherwise we will never be able to get out, and you can't even see this?"

Xiaolu glanced at Ye Yu with eyes that seemed to be looking at a stupid person, and her words were prickly, but Ye Yu didn't bother to bother with her at all, he directly ignored the other party, and then turned his head to look at Yang Yunyi and continued to ask: "Then since you have learned this science, there must be a way to find a way out, right?" ”

"There are methods, according to the theory of "Qimen Dunjia", in the "Eight Gates", the three gates of opening, rest, and life belong to Jimen, death, shock, and injury belong to the murder gate, and Dumen and Jingmen belong to Zhongping, although there are some special circumstances, but in terms of direction, Jimen means a way out, especially "Shengmen", that is to say, as long as we find the direction of "Shengmen", we can leave here safely, but ......" Yang Yunyi said and cast his eyes to the center of the square, looking a little worried and dignified.

"But it is not easy to find out the 'Shengmen' accurately, not only must we first determine the current position, but also we must not make any mistakes in the process of deduction with the help of the compass, otherwise we will miss the slightest and make a thousand mistakes. In terms of the current position, we can use the 'Sinan' in the center to make a determination, but the compass is a big problem......"

Ye Yu followed Yang Yunyi's line of sight and looked at the square, and immediately reacted.

What is presented in front of them now is a "broken" compass, dense text patterns are distributed in a disorderly manner on the hundreds of floor tiles in the center of the square, not to mention whether to find each corresponding fragment for the time being, even if it can be found, how to splice it is a problem, this time it is not as easy to operate as the nine-square grid slider on the previous Qinglong stone door, and Ye Yu did not find that there are vacant floor tiles in the square, obviously the operation method this time is also very different from before.

"However, according to the official instinct, I am afraid that there is a mechanism for restoring the compass hidden on these floor tiles, as long as you can successfully find the mechanism and piece the compass together, it will no longer be difficult to find the 'Shengmen'......" Yang Yunyi retracted his gaze, looked left and right for a moment, and then picked up a stone from not far away.

"Do you want to ......?" Seeing Yang Yunyi's actions, Ye Yu suddenly realized his intentions.

"It's not a way to be stunned here, so it's better to go up and try it." Yang Yunyi signaled Ye Yu to step back, and he stood at the edge of the square with a stone, while Xiaolu at this time had already retreated, watching Yang Yunyi's every move with a wary expression.

After everything was ready, Yang Yunyi cautiously stretched out his hand and threw the stone in his hand towards the center of the square, and at the same time immediately turned around and retreated to Ye Yu's side.

"Smack...... Trample... Tread..."

The stone made a long arc in the air and fell on the surface of the densely patterned floor tiles; And with the gentle bounce of the stones on the floor tiles, the fragments of the patterns reflected on the floor tiles were like shadows on the water surface being disturbed, inexplicably causing ripples, but in the end they were restored to their original state due to the stillness of the stones, and returned to calm.

Yang Yunyi stared nervously at the location where the stone fell, and after waiting for a long time, he still found that there was no other movement in the square, so he had the courage to throw a second stone.

Again, the same ripples, the same no response.

“…… It seems that just throwing stones is not enough, so I'll go up and take a look. Yang Yun said a word, and then walked lightly to the nearest floor tile.

"Wait, I'll go with you." Seeing this, Ye Yu hurriedly wanted to step forward together, but Yang Yunyi stretched out his hand to block it.

"You stay where you are, don't come along!"

"But are you all right? In case ......"

"It's okay to get in the way when there are too many people? You stay there and don't move, I can handle it alone. ”

Yang Yunyi's attitude was tough, and Ye Yu was about to say something more, but he heard Xiaolu's slightly contrived sweet voice float over from behind him.

"If people want to be a guinea pig, let him be a guinea pig, there are never a few stupid people in this world who like to be heroes."

Ye Yu turned his head and glanced at the source of the sound, but saw that Xiaolu began to leisurely examine his nails again, looking like he didn't care about himself. Ye Yu sighed secretly, and when he looked back at Yang Yunyi again, he found that as soon as he turned around, one of the other party's feet had already stepped on the floor tiles covered with strange black pattern fragments.

The black pattern rippled again, like the surface of the water, spreading all the way around Yang Yunyi's moving feet. Yang Yunyi cautiously walked step by step in the direction of the central "Sinan", while closely monitoring the movements around him, but until he walked in front of the huge "Sinan", except for the fluttering patterns on the ground, nothing unusual seemed to happen around him.

"How's it going over there?" Ye Yu's rear shouted anxiously.

As soon as Yang Yun turned around, he made a "temporary safe" gesture to Ye Yu, and then turned his head to look at the giant "Sinan" in front of him.

This "Sinan" is two people tall, smooth in appearance, black throughout, and the material should be made of a magnet, but the strange thing is that the surface of this "Sinan" is faintly covered with a light layer of blue light.

"This light...... It seems to be shining through from within. ”

Just as Yang Yunyi was carefully looking at the "Sinan" in front of him, he suddenly heard Ye Yu's voice next to him, and turned his head to find that Ye Yu had also come over at some point, standing beside him and looking up at the huge "Sinan" in the center.

"But then again, since this thing is also a 'part' of the compass, could it have something to do with the fragments of words under our feet? Or rather...... Is this a key to unlocking the mechanism here? Ye Yu moved his gaze to Yang Yunyi and asked softly.

"Maybe, but I haven't found any clues yet......" Yang Yunyi lowered his head and pondered. Besides, I think there's something strange about this light, so we're careful not to touch it...... Alas? This is!! ”

Before Yang Yun finished speaking, Ye Yu suddenly felt the blue light around him, but this time the light source did not come from the "Sinan", but from below the two of them!

Ye Yu was shocked, looked down, and suddenly found that on the two square stone slabs under the feet of him and Yang Yunyi, at some point, there was a blue glow that was exactly the same as the surface of "Sinan", and the black pattern fragments on the stone slabs not only fluctuated even more, but also rose slightly, floating on the surface of the floor tiles, and looked more and more dazzling and weird against the blue light.

"Not good! Come on!! As soon as Ye Yu saw that the situation was wrong, he pulled up Yang Yunyi and was about to withdraw, but what happened next greatly surprised the two of them.

At that moment, the floating black fragments under the feet of the two seemed to be pulled by a force, flying towards each other against the ground.

Ye Yu only saw a flower in front of him, and before he could move his steps, the blue light on the ground suddenly dimmed, and the original floating pattern seeped into the floor again, only this time, the original black fragments turned blue, and it seemed to be fixed, and there were no more fluctuations and ripples from before.

"It's ...... What's going on?! Wait a minute...... The pattern on the floor tiles seems to have changed as well?? Yang Yun compared the patterns of the fragments on the floor tiles under Ye Yu and his feet back and forth, and was shocked to realize that the patterns on the two floor tiles they had stepped on before had been swapped with each other in the previous series of processes.

"Oh, you two are lucky, you guys stumbled upon the mechanism by mistake." Shinolu's voice rang out from behind the two of them. Ye Yu turned his head to look, and saw that Xiaolu was finally willing to step on the floor tiles and walked towards the two of them.

"Did you see it all over the side just now?" Yang Yunyi asked.

"Heh, of course." Shinoru chuckled disdainfully, and instead looked at the tiles the two had stepped on. "Obviously, there is a sensor device under the floor tiles here, as long as the pressure of the human body weight on the specific two floor tiles at the same time, it will trigger the mechanism to swap the patterns on the two floor tiles."

"Specific floor tiles? There are hundreds of dollars here! Is there any pattern to find out which floor tiles correspond to one by one? Ye Yu questioned.

"It's a pity that there is no pattern. But ......" Xiaolu said and slowly walked back to the edge of the square, then turned around, stretched out her slender jade hand and pointed at Ye Yu casually. "You, three squares to the right in parallel; And Young Master Yang next to you, move two squares to the left and then go two squares to the front. ”

"What do you want to do?" Yang Yunyi stood still, obviously still wary of Xiaolu.

"Show you the way." Shinoru smiled indifferently. "By the way, you and I are in the same boat."

Yang Yun thought for a moment, raised his head and glanced at Ye Yu, and then the two of them no longer hesitated, and tried to act according to Xiaolu's instructions.

And at the moment when the two were in place, the same situation played out again, and the "fragments" on the two floor tiles changed from black to blue after being swapped, and finally fixed.

"How do you know ......??" Ye Yu looked at Xiaolu in surprise, but the latter didn't explain, only to see the corner of her mouth hooked slightly, and a trace of complicated emotions flashed in her beautiful eyes.

"Thankfully, you've met me."
