"It's really unpleasant to feel like this being calculated......"

At this time, Lin Mu on the side shook his head, but while shaking his head, he raised the handle of the embroidered spring knife in his hand and slammed it on the red brick wall beside us.

I was shocked, and the red brick wall collapsed directly in Lin Mu's swing, revealing a large hole for adults to enter and exit.

For a while, the dust was everywhere, and Lin Mu didn't care about it, and after fanning it casually with his hand, he stepped into the big hole in the red brick wall that he smashed out with the handle of the embroidered spring knife.

Seeing this, Shen Li and I, of course, also followed Lin Mu, and together we entered the space on the other side of the red brick wall.

It's just that when Shen Li and I followed Lin Mu into the other side of the red brick wall, Shen Li and I couldn't help but stop.

It's not because we found anything wrong, but Lin Mu, who was the first to step into this red brick wall, stopped at the side of this red brick wall, with a pair of frowning eyes, staring straight at the standing figure in front of us.

Seeing this, of course, I also looked at the figure standing in front of us, but I was stunned when I saw the figure clearly.

Because at this time, the figure we saw in front of us, that is, we saw through the small hole on the side of the red brick wall just now, is not a sculpture at all, but a real person......

Yes! A real person! A man dressed in shabby clothes, all facing the red brick wall!

It's just that this person has no flesh and blood, only a dry bone remains, but even so, this dry bone is standing straight, and one hand is still stretched straight in the direction of the red brick wall.

Don't think about it, before this dry bone died, he must have tried to escape from the red brick wall, but when he stretched out his hand towards the red brick wall, something took his life.

And the thing that took his life must have been very fast, otherwise it would not have allowed this dry bone to maintain a standing and outstretched posture after death......

"This man was pierced through the heart and died......"

At this moment, Lin Mu on the side opened his mouth again and pointed to the position of the dry bone's chest.

I looked along, and sure enough, I only saw the bone in the chest of the dry bone, and the bone in the chest of the dry bone was obviously damaged, and its damage was also in the shape of a very neat round hole, indicating that the dry bone, as Lin Mu said, was killed by something that directly penetrated the heart at a very fast speed.

It's like a bullet that directly ends the life of this dry bone in an instant, so this dry bone will keep a standing posture and not fall...... Wait a minute!

My heart moved, and I stared at the red brick wall directly in front of the dry bones, and of course at the small hole in the red brick wall.

Really! The small hole in the red brick wall is completely straight to the small hole in the chest of the dry bones, indicating that what penetrated the chest of the dry bones also penetrated the red brick wall after penetrating the chest of the dry bones......

How powerful does this have to be? Bullets alone won't do it anyway!

Surprised, Shen Li on the side shook his head again.

"If there's really anything that can penetrate a person's chest and then a red brick wall, then there's only one possibility......"

"What is possible?"

I stared at Shen Li and asked.

"Sniper Rifle ......"

Without waiting for Shen Li to respond, Lin Mu on the side took over again.

"This kind of power can only be achieved by a heavy sniper rifle."

I listened suddenly, and Shen Li on the side shook his head again.

"But when the little devils invaded our country, heavy sniper rifles were not popularized at all, and there was no trace of gunpowder or metal friction in the round hole in the red brick wall and the wound on the chest of the dry bones......"

"That means ......"

I stared at Shen Li and frowned, and I couldn't help but sigh in my heart.

Shen Li nodded, staring straight at the small hole in the red brick wall.

"It is not bullets that penetrate this red brick wall and dry bone chest......"

I listened widely, and of course I also asked Shen Li, if it weren't for bullets, what could have penetrated the red brick wall with such great power, while penetrating the chest of the dry bones.

"I don't know ......"

Shen Li turned back and looked into the depths of the space behind the red brick wall.

"But that thing, maybe it's still in this underground fortification......"

I shuddered as I listened, and I also turned my head to look into the depths of the space on the other side of the red brick wall.

It is still a concrete passage, and there are still a lot of ghostly insects floating, but unlike the previous two underground fortifications, the passage of this underground fortification is filled with a strong and lingering aura of resentment.

"Let's go, I don't know where Huiguo went......"

Lin Mu shook his head in a deep voice, took one last look at the dry bones standing, turned around and walked towards the depths of the passage in the red brick wall.

Seeing this, Shen Li and I of course followed Lin Mu, and of course we always held our respective weapons tightly, guarding against attacks that might come at any time.

We walked through the passage with trepidation, until a corner appeared in front of the passage, and when we turned the corner, we couldn't help but stop walking.

Because behind this corner is a scene that has not appeared in the two underground fortifications we have passed before.

Yes! Behind this corner, though still a passageway, it was wider than any underground fortification passage we had entered, and on the right side of the passage, at intervals, there were iron doors that seemed to be divided.

He glanced at Shen Li and Lin Mu, and was about to ask them if they wanted to search every room.

At this moment, a black shadow flashed through the depths of the passage directly in front of us, and directly entered the iron door of the third room on the right wall of the passage.

"Huiguo!"

Without hesitation, Lin Mu chased after the first one with a low voice, of course, Shen Li and I also followed Lin Mu closely, until we ran to the door of the third room on the right side of the passage, the right wall of the passage and the door of the third room had already opened, of course, it must have been the black shadow that flashed into this room just now.

As for whether the black shadow is Huiguo or not, none of us is sure......

Thinking of the dry bones standing in front of the red brick wall just now, Shen Li and I grabbed Lin Mu's shoulders at the same time and made a silent gesture at him.

Although Lin Mu looked anxious, he also nodded slightly after seeing our silent gesture, and did not rush directly into this room.

Then, holding his breath and lowering his pace, he entered the iron door of this room step by step.

Of course, after entering the iron door of the room, he leaned directly against the wall on the side of the iron door of the room, and quickly scanned the entire room.

Then, I saw that this room was only twenty or thirty square meters, and there were also a lot of ghostly insects floating in it.

And by the light of these ghostly insects, I saw that the room was surrounded by a mess.

A collapsed bookshelf in the corner, an old wooden table against the wall in the center, a mess of paper, pens and small objects on the wooden table, and an old wall clock hanging on one wall.

Glancing, a heart gradually sank, because although this room is boxy, there is no other layout, can be completely seen, but because of this, we did not see any trace of 'people' in this room......

Yes! There was no sign of a 'person' in this room, and we had just seen a figure enter this room!

Of course, this made me feel uneasy, and Lin Mu followed and pointed to the collapsed bookshelf in the corner of the room.

I nodded, and with Lin Mu, I walked around behind the collapsed bookshelf in the corner of the room.

If there was any room in this room where there was a single person, it would be the collapsed bookshelf in this corner.

Although the collapsed bookshelf in this corner can only cover a person lying on the ground, it is still possible......

Holding his breath, he also clenched the black knife in his hand, and walked with Lin Mu step by step around the collapsed book sword and walked to the back of the collapsed bookshelf.

However, there was nothing, the back of the collapsed bookshelf was empty, and there was no one hiding in it......

But since there is no one behind this bookshelf, where is the figure we just saw outside and flashed into this room?

Could it be that the figure had gone out of the room through the door again before we entered?

No way! If that were the case, we'd be aware of it, because we'd been staring around the door when we were running to it.

So, the figure that flashed into this room, whether it was Huiguo or not, where did he go at this time?

Could it be that after entering this room, the world has evaporated?

Thinking about it, the uneasiness in my heart became more and more intense.

And at this moment, behind me and Lin Mu, there was a sound of Shen Li's "huh".

My heart moved, and I quickly looked at Shen Li, thinking that Shen Li had found the trace of the figure who entered the room?

However, when I looked at Shen Li, I realized that Shen Li at this time was staring straight at the top of the wall on one side of the room.

And above the wall on one side of the room, she was staring at the old wall clock.

"What's wrong? What's wrong with this wall clock? ”

I stared at Shen Li and whispered, Shen Li shook his head slightly, and his eyes never left the wall clock.

"This wall clock is still walking......"

I was stunned for a moment, and took a closer look at the wall clock again, and sure enough, although the wall clock was old, the second hand in it was indeed still moving!

But how can a wall clock that has gone through dozens of years and nearly a hundred years still move around as usual?

Can't you run out of battery power in this wall clock? Or is there something else, like something changing the battery for this wall clock all the time......

With a slight tremor in his heart, he also went to Shen Li's side, and also looked at the wall clock on the wall.

"Jiang Wusheng, do you think that although this wall clock is old, the dust on it is obviously thinner than the dust on the surrounding walls?"

Shen Li asked, and I also forced down the horror in my heart and nodded.

Yes! The surface of the wall clock on this side of the wall is obviously not as thick as the dust on the surrounding wall, which indicates that the wall clock is not hanging on the wall all the time, and at least every once in a while, something removes it, so the dust on this wall clock is thinner than the surrounding wall......

Of course, if there is really something that removes the wall clock from this wall every once in a while, then it must be to replace the battery of this wall clock and correct the time of this wall clock......

In other words, 'time' is very special in the underground fortifications at the source of this evil cave, and it must be accurate at all times......
