Not bad! A subtle, "woo-woo" sound came from one side of the concrete passage!

I glanced at it, and I couldn't help but feel a sigh in my heart, because I could only see that the direction of the "woo-woo" sound was on the corner of the concrete passage......

Yes! The direction of this "woo-woo" sound is the other side of the corner of the concrete passage, that is, in the passage where the red brick wall is located!

No, we're just in the passage where the red brick wall is. Coming out, there was nothing in the passage where the red brick wall was...... Wait a minute!

My heart moved, of course, I thought of the secret passage, and after glancing at Shen Li, I quickly approached the corner of the concrete passage.

I lowered my pace and walked quickly, until we leaned against the wall at the corner of the concrete passage, and the sound of "woo woo" in our ears became clearer and clearer.

Then, as I leaned against the corner wall and looked to the other side of the corner, I couldn't help but frown.

Because I only found that although on the other side of the corner, there was a constant sound of "woo woo", but this "woo woo" sound was not from the red brick wall passage on the other side of the corner......

Not bad! This "woo woo" sound is not coming from the red brick wall passage, but from behind the red brick wall of the red brick wall passage!

Yes! This 'woo-woo' sound actually came from behind the red brick wall of the passage on the other side of the corner!

I was shocked, but Shen Li shook his head slightly.

"Maybe Huiguo entered the red brick wall because of a secret passage......"

After speaking, Shen Li walked out of the corner and strode towards the red brick wall.

Of course, I followed her, and by this time, Lin Mu, who had been in the concrete passage closest to the gate of the underground fortification, had also come over and asked what we had found.

Hurriedly waved his hand to let Lin Mu not make a sound, and then pointed to the red brick wall in the passage on the other side of the corner.

Lin Mu glanced at the red brick wall, of course, he also heard the sound of "woo woo" that was still coming, understood what I meant, nodded at me, and approached Shen Li at the front with me.

It wasn't until we went to Shen Li's side that the red brick wall was completely pasted, and the sound of "woo woo" from inside the red brick wall was naturally clearer in my ears.

It's just that because of this clearer, I only found that the sound of "woo woo" coming from inside the red brick wall turned out to be a subtle and trembling cry......

Yes! The sound of "woo woo" coming from the red brick wall turned out to be a faint cry, and this crying is still a little familiar, it seems to be ...... It's Huiguo's voice!

I was shocked, and Lin Mu beside me raised his hand directly, and was about to use the handle of the embroidered spring knife to smash the red brick wall on the side.

And at this moment, Shen Li grabbed Lin Mu's wrist and stopped Lin Mu.

"We don't know what's going on inside this red brick wall yet......"

Shen Li shouted in a voice that only we could hear, and Lin Mu gritted his teeth, strode to the side of the red brick wall passage, stretched out his hand and groped the wall to search it, of course, looking for the possible hidden passage mechanism in the red brick wall passage.

Seeing this, Shen Li and I, of course, also went to the wall on the other side of the red brick wall passage and searched the wall on the other side.

Shen Li is right, we don't know the situation on the other side of the red brick wall now, we don't know how Huiguo got to the other side of the red brick wall, and we don't know why Huiguo is crying on the other side of the red brick wall.

So we can only find the secret passage first, and then find the secret passage to enter the other side of the red brick wall, and figure out the situation inside before acting.

However, the development of events has not been as gradual as we imagined.

Just as we searched the walls on both sides of the red brick wall, in the red brick wall, the original faint crying sound of Huiguo suddenly increased, and with Huiguo's crying, another strange muffled sound also came from the direction of Huiguo's crying sound from the red brick wall.

I was shocked, because the muffled sound that came from Huiguo's crying sounded like someone was beating Huiguo!

Yes! The muffled sound was like the sound of a man smashing his fist on another person!

Without the slightest hesitation, and without continuing to search the walls on both sides of the passage of the red brick wall, Shen Li and I ran to the red brick wall, and Lin Mu, who ran to the red brick wall on the other side, was the fastest one, and after running to the red brick wall, he raised his hand and smashed it towards the red brick wall with the handle of the embroidered spring knife in his hand.

For a while, with a loud bang, this already fragile red brick wall was directly smashed out of a half-person-high hole by Lin Mu, and Lin Mu also went directly into the red brick wall and went to the inside of the red brick wall.

Of course, Shen Li and I also hurriedly followed, and at the moment of drilling into the red brick wall, we held the black knife and looked at the source of Huiguo's crying and muffled noise.

However, when we looked at the source of Huiguo's crying and smashing sounds, I only saw that the source of this sound was only Huiguo......

Yes! This is clearly the source of Huiguo's crying and smashing-like sounds, and Huiguo is the only one......

"How so?"

I couldn't help but mutter, and then, I saw that Huiguo, who was crouching on the side of the red brick wall, raised his hand and slammed it into his chest.

There was a muffled sound, and Huiguo also wailed......

I'll go, the reason why Hui Guo's wails and muffled sound of smashing things can be heard from this red brick wall is because Hui Guo is raising his hand to smash his chest?

What's going on?

For a moment, I couldn't help but think of Huiguo being by a baby in that school-like gray building......

No, at this time, Huiguo was taken on by something again?

Of course, I couldn't believe it, and I also let out my perception to probe.

There is no abnormality, and there is no other strange aura on Huiguo's body, which means that Huiguo has not been put on the body by something wrong at this time.

But since Huiguo wasn't caught by something wrong, why did he raise his hand and smash his chest?

Without waiting for me to think about it, when Hui Guo raised his hand again and wanted to smash it into his chest, Lin Mu stepped forward and directly grabbed Hui Guo's raised wrist.

"What are you doing?"

Lin Mu stared at Hui Guo, who was still wailing, and stared straight at him.

"...... not found"

Hui Guo shook her head with a trembling mouth.

"Can't find ...... Can't find ......"

I frowned when I heard this, and it occurred to me that the reason why Huiguo entered this underground fortification was to 'find Huiguo'.

At this time, Huiguo said that he couldn't find ......

Before I could analyze too much, Huiguo, who was grabbed by Lin Mu's wrist and kept shaking his head and saying "I can't find it", suddenly shook off Lin Mu's wrist, got up and turned around and ran to the front of the passage in the red brick wall.

Yes! Hui Guo shouted "I can't find it" and ran to the front of the red brick wall passage!

Of course, this surprised me, and of course I hurriedly chased after Lin Mu and Shen Li.

However, this time, Hui Guo was completely crazy towards the front of this passage, so that we couldn't catch up with him for a while.

It wasn't until we chased like this for a few minutes that we finally got into a distance with Huiguo, who was running like crazy, and we were about to control Huiguo.

However, at this moment, the end of the passage appeared in my line of sight.

Yes, the end of the passage in the red brick wall is not far in front of us at this time, and the moment I saw the end of this passage, I felt a chill in my heart, and I directly stopped chasing Huiguo.

Because what I saw was a hellish scene......

Yes! The end of the passage inside this red brick wall is a completely hellish scene.

A piece of uneven rock, obviously the same as the previous underground fortifications, and when the little devils abandoned this underground fortification, they were also digging the rock layer of this underground fortification.

However, the rock layer at the end of the passage behind the red brick wall is completely different from the rock layer excavated in the previous underground fortifications, because the rock layer at the end of the passage is inlaid with broken limbs......

Yes! In the rock layer at the end of this passage, there are countless limb bones!

There were arms, leg bones, and even so many skeletons, and they all melted into this rock layer, one buried in the rock, one exposed!

Dense, innumerable, all of them were reflected in my eyes, and I could even imagine their struggle at the last second before death from the appearance of these broken limbs......

"Grass ......"

involuntarily scolded, of course, it was instantly determined that the bones in these rock layers must be inseparable from the little devils back then.

Just like the compatriots who were abandoned behind the red brick wall in the underground fortifications we first entered, the bones in these rock layers are only afraid that they are also persecuted by our people.

Gritting his teeth fiercely, Huiguo, who rushed to the front, slammed into the rock layer full of broken limbs, and cried and shouted loudly while waving his hand at the rock layer.

"I can't find it...... I can't find Huiguo......"

I frowned when I heard this, and of course I didn't understand why Huiguo was pulling at this rock layer full of broken limbs and saying the phrase "Huiguo can't be found".

Of course, he didn't think much about it, and Lin Mu and Shen Li stepped forward to control Huiguo.

And this time, Lin Mu directly slashed at the back of Hui Guo's neck with a hand knife, causing Hui Guo to faint as soon as he rolled his eyes.

Seeing this, he breathed a long sigh of relief, and Shen Li, who was beside him, suddenly made a move that made my heart chuckle......

She suddenly grabbed my hand and took a sharp step behind her.

Shen Li, a calm and composed person, would take a step back, which only means that she must have discovered something terrible.

I quickly followed the direction of the rock layer that Shen Li was staring at, however, I found nothing except a piece of bone and bone fragments that were integrated into the rock layer.

"What's wrong, Shen Li? What did you find? ”

As I stared at the rock formations full of broken bones and stumps, I leaned closer to Shen Li's ear and asked.

"Something is wrong......"

Shen Li shook his head slightly and muttered, and the eyes of the stars staring at the rock layer were also completely wide.

"What's wrong?"

I frowned and asked, and Lin Mu on the side took Huiguo and retreated to us in the same way.

"Little Brother Jiang, haven't you seen it yet? Fragmented bones and limbs in these rock formations...... Not people! ”
