Darkness, like a huge net that swallows space, spreads step by step along the breath and along the heartbeat.

The white light, like a sharp blade that splits through chaos, shines brighter and brighter through the wrench, reflecting the truth layer by layer.

The violently beating heart gradually calmed down, and his breathing was no longer trembling rapidly due to nervousness, Shen Xiao stopped, looking at the so-called weird "human form" in front of him, and he couldn't cry or laugh in his heart.

It seems that I was really nervous just now, how can I think of this thing as a "person"?

Shen Xiao laughed at herself inwardly, and once again raised the wrench that she used as a flashlight, focusing the light on the object in front of her.

In the white light, an old valve controller with a joystick was quietly placed in a hidden corner.

I saw that this controller is almost half a person tall, and the size is not small. The appearance of the main body is similar to a regular triangular pyramid, a long metal control rod extends from the top of the side of the triangular pyramid, reaching straight in one direction, and the end of the control rod is covered with a spherical handle, but this handle is wrapped in layers of heavy isolation cloth, making the volume of this sphere appear a little too large - this is also the part that was mistaken by Shen Xiao for a "human head" before.

When viewed from the side, the silhouette of the entire instrument does resemble a "person" sitting on his knees, not to mention that it is in such a chaotic and unclear environment before. However, the direct reason that caused Shen Xiao to admit his mistake was another point-

"Temperature".

This is also the strangest thing about this instrument.

Shen Xiao cautiously approached the controller and squatted down lightly on the side. Sure enough, as shown in the previous infrared thermal image, the main body of the controller was exuding bursts of unusual heat, and even Shen Xiao on the side could faintly feel the bursts of heat.

Shen Xiao carefully observed the controller in front of him, and then seemed to have discovered something, so he immediately adjusted the wrench switch and concentrated the light on an area below the right side of the main body of the instrument.

I saw that a square shell was missing from the side of the controller, and when I looked inside the machine through the broken shell, I could see that there was a large circuit board inside, and the components on it were bouncing with bursts of electric sparks.

With just one look, Shen Xiao discovered the problem, and at the same time, she finally understood the reason why the machine emitted such unusual heat.

Short-circuited...... And it seems that someone has deliberately tampered with it.

Shen Xiao stood up and swept forward with the light on the wrench, only to find that a few steps away from this valve controller was a stone wall, which meant that the position she was in now was a dead end.

Out of the way? That is to say......

Shen Xiao once again moved his gaze back to the short-circuited old-fashioned valve controller, and suddenly had a number in his heart.

Obviously, it seems that only through this controller can a new channel be opened, and as for how to repair this artificially damaged controller, this is not a difficult task for ace mechanic Shen Xiao.

Shen Xiao carefully observed the circuit board inside the machine again, and then decisively removed the black wrench on his thumb, and in just a moment, the wrench changed shape again and returned to the mechanical beetle at the beginning.

After setting some parameters, Shen Xiao flicked his fingers, and the beetle began to move, passing through the gap on the side of the controller and flying straight into the machine.

Soon, the temperature of the controller gradually cooled down, and after adjusting it several times with full concentration, a happy smile finally appeared on Shen Xiao's face.

Nailed it.

The dim indicator light is on again, and the sound of "Zizi" indicates that the controller has regained its basic vitality.

Now that the machine has been repaired, the next step is to hurry......

Shen Xiao was worried about the safety of his companions, so he hurriedly reached out and grabbed the spherical handle at the top of the control lever and pulled it down hard.

"Boom—"

With the activation of the controller, the passage suddenly vibrated violently, but to Shen Xiao's surprise, there was no secret door around to open in response, but as if something had been activated, and the friction sound of mechanical gear occlusion suddenly sounded around it.

"Click...... Click...... Click......

"Click...... Click......

"Click......

The sound came from near and far, and it seemed that it was all moving in a certain direction. As soon as Shen Xiao, who was shocked, came back to his senses, he suddenly felt a strange feeling rushing from behind him.

"Who ......!"

Before he could say anything, he received a blow to the back of the head. Before Shen Xiao, who had no time to turn back, his eyes suddenly darkened, and then he completely lost consciousness.

－－－－－－－－－－－－－－－－－－－－－－－－－－

"Huh......?"

Ye Yu stopped and looked up at the top of the square with some hesitation.

"Why are you still stunned?? Hurry up! Xiaolu stood on the periphery of the square, with one hand on her waist, and the other hand pointing at Ye Yu in the square.

"You ...... Did you hear anything just now? Ye Yu retracted his gaze and turned to the other two companions and said.

"Are you hallucinating? What a sound! Xiao Lu pulled her sweet voice and rolled her eyes dissatisfiedly at Ye Yu.

"Strange, I obviously ...... just now" Ye Yu just spoke, but was blocked back by Xiaolu.

"Okay, don't bother anymore, it's all because you're so slow that this girl wasted hours here!"

"This place is so big, if you think we're slow, why don't you go into battle yourself?" In Xiaolu's chatter, even Yang Yunyi was a little annoyed.

"Because of this girl, I have to show you the way." Shinoru smirked, making no secret of the sarcasm in her words. "If Young Master Yang has any dissatisfaction, why don't you take command? Oh yes, if you can memorize all the details on the compass~"

Yang Yunyi's face froze, and he sighed secretly. Although he was unhappy, he could only swallow his anger, because the reality was that among the three of them, it was true that only Xiaolu knew the details on the compass, and thanks to her, he could restore the broken "Compass Square" to this point.

There was not much left of the black pattern on the ground, and in its place was a large complete blue text and pattern, which formed a concentric circle after ring around the central "Sinan".

"If it weren't for the knowledge that this girl had accumulated before, even if you knew the mechanism here, you would be helpless, right?" Shen Xiao looked at Yang Yunyi's helpless look and smiled even harder. "Okay, stop talking nonsense, there are only the last two pieces left, hurry up!"

Ye Yu and Yang Yunyi didn't want to delay any longer, and immediately found the only two remaining floor tiles with black pattern fragments according to Xiaolu's instructions.

"This is the last, are you ready?" Yang Yunyi raised his head and exchanged glances with Ye Yu, who nodded and stared nervously at his feet.

"I counted down to three seconds and stepped on it together. Three...... Two...... One! ”

At the moment of the countdown, Ye Yu and Yang Yunyi stood on the floor tiles at the same time, and at the moment when the floor tile patterns under the feet of the two were exchanged, the difference suddenly rose.

The blue light on the giant "Sinan" in the center suddenly flourished, not only that, but the words, patterns, and even the cracks in the floor tiles all had blue light transmitted from the ground, and the entire space was suddenly surrounded by a piece of blue.

At the same time, the three of them suddenly found that the "Compass Square" in front of them actually began to move on its own, this "movement" was not the physical movement of the floor tiles, but the complete compass pattern reflected on the floor tiles began to rotate on its own with large and small concentric circles.

Ye Yu and Yang Yunyi hurriedly withdrew from the inside of the square, and together with Xiaolu, they witnessed everything that happened in front of them at the edge of the square.

After a few moments, the movement subsided. I saw that the huge compass finally stopped, and at the moment when the dust of the compass settled, eight secret doors of different colors suddenly appeared on the wall of this closed circular square.

Eight secret doors, eight directions, around the central "Compass Square", opened a circle.

"Open, rest, life, injury, Du, scene, death, shock...... That's right, these secret doors correspond to the direction of the "eight gates" on the compass! Yang Yunyi pointed to the circle of words in the center of the compass and said excitedly.

"That means that we are going to take the ...... corresponding to the direction of 'Shengmen'" Ye Yu followed the words 'Shengmen' on the compass and moved his gaze to the black secret door directly in front of him.

"Now that we've found a way out, why are we still stunned?" Xiaolu raised her hand and glanced at the rest of the exam, anxiously urging the two of them.

"Okay, then let's ...... Alas? Ye Yu suddenly stopped and looked up at the top of the square again.

"What's wrong with you?" Yang Yunyi, who was in front, turned his head and looked at Ye Yu and asked.

“…… Forget it, it's nothing, let's hurry up. Ye Yu said, and together with Yang Yunyi and Xiaolu, he stepped into the black secret door.

……

"Click......

A faint sound came from the top of the square.

"Click......

"Click...... Click......

"Click...... Click...... Click......

The sound of the mechanical gears clashing became louder and louder, penetrating through the ceiling and along the walls, gradually penetrating into the underground of the "Compass Square".

In the noise, the central "Sinan", which had been stationary before, actually began to rotate slowly, and with the change in the direction of "Sinan", the "compass" on the ground also began to rotate again, but this time, the speed of the "compass" accelerated significantly, and at the same time, the blue light that originally enveloped the entire space also unconsciously turned red like blood.

……

"Sinan" slowly stopped turning, the red light gradually disappeared, and the compass on the ground finally came to a complete standstill.

"Open, rest, life, injury, Du, scene, death, shock".

There are still eight secret doors standing in eight directions, but this time, the words in the compass pointing to the black secret door that Ye Yu and they entered have quietly changed-

"Death's Door".
