From that corner, about twenty or thirty meters ahead, a huge hole appeared. A white glow appeared at the entrance of the cavern, like the glow of some kind of bright lighting system. From time to time, there were one or two square, gray shadows, whizzing from the bottom to the top of the cave. Although the spotlight on Haoyi's armor can shine on those square things, it can only be seen roughly, and it seems to be some things in iron boxes.

Hao Yi frowned, thought for a moment, then turned off the tactical spotlight on the armor, closed the holographic mask, turned on the night vision system, raised the rifle, and slowly paced towards the hole step by step.

"Whew-whew!" The squares whistled past the hole about every half a minute, with the faint roar of a machine engine.

"Click, click!" The sonorous sound of CMC's armored combat boots stomping on the ground and the low roar echoed in Haoyi's ears, and the aiming aura in the holographic helmet had already lassoed the whistling square object, and the thumb had hooked the trigger. Once there was any change in those things, Haoyi would not hesitate to let them taste the taste of the spike bullets.

However, when Hao Yi walked all the way to the light at the entrance of the cave, those things were still shuttling up by themselves, ignoring Hao Yi who was approaching with a rifle.

"I'm X, what's this?" Hao Yi saw that the light at the entrance of the cave was too strong, so he turned off the night vision system, and a spectacular scene appeared in front of him.

A large crater with a diameter of nearly 100 meters, like a giant interstellar missile silos, is connected from top to bottom with thick steel cables, and on the steel cables are hung open iron boxes three or four meters wide and two or three meters long. The iron boxes were divided into two groups, and the iron boxes on the two adjacent steel cables ran in opposite directions, one group flying upwards and one group falling down. The upward swinging iron box was filled with gray-black dirt, like volcanic rock.

Around the walls of the big cave, there is a huge helium lamp at every interval, which illuminates the scene inside the cave clearly. Rao is like this, Haoyi probe looked, above the head can only vaguely see a large platform, a large iron box on the back and forth of the left and right frequent movement, under the feet is like an endless abyss, the bottom of the hole at the bottom of Haoyi seems to be only the size of a grain of rice, a dazzling light, there seems to be a faint sound of human voices and machine roar up.

"What the hell is this place?" Hao Yi was wondering if he had really crossed underground. Suddenly, there was a stabbing sound overhead. The sound was obviously different from the sound of those iron boxes moving up and down, Hao Yi was slightly surprised, looked up and followed the sound, and saw something similar to a cable car car, slowly falling from top to bottom. Haoyi's heart moved, and he hurriedly took a few steps back, flashing to the dark place in the cave.

As soon as Hao Yi hid his body, the elevator slowly swept through the hole where Hao Yi was hiding. Although the elevator was located in the middle of the big hole, and the speed was not slow, Haoyi still had a rough view of the scene on the elevator. On the simple cable car stood two or three soldiers in CMC armor, as well as a man who looked like an officer. Looking at the color of the soldiers' armor and the officers' uniforms, it doesn't look like they belong to the federal army.

"Me X, rebel?" Hao Yi thought in surprise: "Could it be that Lao Tzu has worked so hard to dig holes in the ground like ground mice, and he actually dug into these dogs' nests?" It's not right, these dogs are going to live underground? What do you want to do when you dig such a deep hole? Could it be some conspiracy? Looking at the scene in front of him, Hao Yi couldn't help but be confused, couldn't figure it out for a while, and fell into deep thought.

I don't know how long it took, and suddenly there was a sound of a stone rolling behind him, although it was very slight, but it was still transmitted into Hao Yi's ears through the external sound sensing system on the armor, and Hao Yi woke up suddenly.

Almost subconsciously, as soon as Hao Yi turned around, the muzzle infrared holographic aiming point of light hit it, which was reflected on Hu Erfat's somewhat pale little face. Hu Erpang was holding a rifle in one hand and a small flashlight in the other, and his probe probed around the corner, and behind him was Catherine, who was also a little trembling and only revealing a pair of dark eyes.

"Two fat? Why are you two here? Hao Yi was stunned for a moment, then reopened the tactical spotlight on the armor, and after seeing that it was the two of them, he asked with wide eyes and surprise.

"Brother Hao, what's wrong, what's wrong? No, are you alright? Maybe it was because he was too nervous, Hu Erpang stammered: "We, seeing that you haven't moved for so long, we're a little worried, so let's come and take a look!" ”

"9527, are you alright?" Catherine leaned out from behind Hu Erpang and asked softly with concern.

"Cut! With your wise and martial Brother Hao, what can happen? For the care of the two of them, although Hao Yi's heart warmed, he still shouted in his mouth: "Come here, let you see the new world discovered by Brother Hao, oh no, it should be a new big hole!" As he spoke, Haoyi put away his rifle and beckoned to the two.

"Huh? Why is it a cave again? Hu Erpang moved over, looked at it, and wailed: "Brother Hao, I said what's wrong with us?" If you go around and around, you won't be in the cave maze, right? ”

"No, it's a big hole!" Catherine blinked her beautiful eyes, looked curiously at the scene before her, and said, "You see that the wall of the cave is smooth and clean, as if it had just been dug up. And those cable cars, like, like, like the transport cable cars in the mines. ”

"Second fat, Brother Hao should really criticize and criticize you! You're not as knowledgeable as the nurse sister! Hao Yi pursed his lips and was about to say two words about Hu Erfat, when suddenly a simple elevator rose from the bottom to the center of the big cave, Hao Yi listened to the sound and glanced down, and hurriedly beckoned the two to hide in the shadow of the cave.

There were still a few rebel marines on the elevator, and they seemed to have seen a lot of the small caves around the cave wall and connected to the main mine, so they didn't look carefully at the cave where Haoyi and the three of them were.

After the elevator flew up, the three of them moved to the entrance of the cave and looked up and down at the mysterious giant mine.

"Brother Hao, I'm wondering, is it that these dogs want to build a bird anti-orbital gun here?" Hu Erpang seemed to be apprehensive about the incident of the railgun accidentally injuring friendly troops, and he thought of the anti-orbital artillery base in the conditional launch.

Hearing this, Hao Yi nodded, opened his mask and frowned, staring at the movement under the cave for a while, and suddenly waved his hand and said, "Whatever the hell is the railgun, anyway, we have to think of escaping from this ghost place first!" ”

"Uh, Brother Hao, then how do we escape?" Hu Erpang smiled bitterly and asked, "There is no staircase on this slippery cave wall, and that elevator is at least fifty meters away from us. Could it be that we have to put wings on ourselves and fly up? ”

"......" Haoyi was speechless for a while.
