But why keep the time accurate? And what will be the 'thing' that keeps maintaining this wall clock and not letting time go wrong?

Could it be the one that pierced the chest of the skeleton in front of the red brick wall and killed it?

Of course I couldn't figure it out, and at this moment, Lin Mu, who also came to us on the side, stared at the wall clock again.

"On this wall clock...... It seems to be marked......"

I was stunned for a moment, and Lin Mu pointed to the top of the wall clock, the time scale position of twelve o'clock.

I took a look, and sure enough, there was a red mark on the twelve-o'clock scale just above the wall clock, and that mark was the same as the other underground fortification markers on the cowhide map, a 'cross'......

"What do you mean?"

I glared at Shen Li and Lin Mu, but I already had a guess in my heart.

Lin Mu shook his head slightly and pointed to the wall clock again.

"It's already eleven fifty-six, and we'll know what the mark on the wall clock means in ten minutes."

I frowned when I heard this, and quickly looked at the wall clock again, and it was only then that I noticed that the time on the wall clock was exactly 11:56 as Lin Mu said, and it was only four minutes away from the 12 o'clock marked in red......

Secretly swallowing his saliva, Shen Li on the side turned sharply again, facing the wooden table against the wall on the other side of the room.

My heart moved, and I also turned to look, but I saw that Shen Li had already grabbed the pens scattered on the wooden table, and quickly drew a stroke towards his palm.

That's right, the pens scattered on the wooden table, painted on Shen Li's hand, are exactly the same red as the wall clock mark......

"The mark on this wall clock was drawn by the little devil back then......"

Shen Li said, staring straight at me.

"Jiang Wusheng, according to the marks on your map, the 'fork' and 'hook' of the little devil should have the same meaning as the marks of our country, one represents good, and the other represents bad.

That is to say, when the clock goes to twelve o'clock, something bad will happen in the underground fortifications......"

After speaking, Shen Li strode to the door on the side of this room and locked the door directly.

Seeing this, of course, I also tightened my heart, and stared straight at the wall clock on the side of the wall, of course, I also stared straight at the second hand in the wall clock.

It wasn't until Shen Li turned around and walked back, pulled me and Lin Mu, and squatted beside the wooden table against the wall, of course, after squatting down against the wooden table, staring straight at the time on the wall clock.

In this way, as if everything had frozen, we stared intently at the wall clock until it came to the last seconds of twelve o'clock under our watchful eye.

Five...... Four...... Three......

I counted silently until I counted to one, and suddenly, a loud alarm bell exploded from outside the door of the house, and resounded throughout the underground fortifications......

Yes! There was a banging alarm bell, and when the wall clock reached twelve o'clock on this wall, it exploded directly outside the room, and my heart was beating wildly when I heard it.

It's as if when this alarm bell rings, the war that has been sealed in the long river of history will strike again......

For a while, he stared at the surroundings of the room, especially the door on one side, and his perception was also released to the greatest extent, alert to everything that was coming.

However, nothing came, and after a few minutes, there was still silence in the room and in the passage outside, and nothing happened at all......

"That's not right......"

Shen Li beside him muttered.

"That's right, don't you really expect something to happen?"

I stared at Shen Li and raised my eyebrows, and I breathed a sigh of relief, but at this moment, in the corner of this room, in the direction of the collapsed bookshelf, there was a sudden strange noise......

Yes! There was a strange sound, it was the sound of the books in the bookshelf hitting the ground, as if something was hiding in the bookshelf and moving in the bookshelf, so that the books in the bookshelf that had collapsed fell directly to the ground......

For a moment, Lin Mu and I looked at the collapsed bookshelves, and of course thought of the figure that flashed into this room through the outside passage.

Yes! The figure vanished into the room, and now it seems likely that it was hiding in the bookshelf......

When we went to check just now, we only looked at the back of this bookshelf, not the bookshelf, and learned that the various squares in this bookshelf were the hiding places of the figures that flashed into this room!

Without hesitation, he clenched the black knife in his hand, and once again approached the bookshelf in the corner of the room with Lin Mu.

Of course, this time we didn't stare at the back of the shelves, but at the inside, alert for any anomalies that might happen in the shelves.

It wasn't until we stepped to the side of the bookshelf and looked carefully at the bookshelves.

Once, twice, other angles......

It wasn't until Lin Mu and I held our respective weapons and looked at the collapsed bookshelf several times from all angles.

Surprisingly, there was nothing in the collapsed shelves, or rather, at least in our search, nothing but a mess of books scattered on the floor.

Could it be that the sound just now was just the sound of the books on the bookshelf falling to the ground?

But I don't know how many years ago, after so many years, when did it not fall off, but we only fell off when we entered this room?

Of course, this is a very coincidence, and all the coincidences in this world may not be coincidences......

Glancing at Lin Mu, they grabbed one side of the bookshelf with their hands that were not holding weapons, and after nodding their heads at each other, they worked together to move the entire bookshelves and throw them to the other side of the corner of the room.

Of course, while lifting the bookshelf, he stared at the scene under the bookshelf.

However, there was still nothing unusual, the scene under the bookshelf was a messy number of books that had fallen on the ground, and there was no trace of anyone at all.

Of course, this made me frown, and Lin Mu on the side also scolded in a low voice, raised his leg and kicked the messy books on the ground.

However, it may have been the injury, although Lin Mu successfully kicked the messy books on the ground, he also turned pale and squatted aside and hugged his feet tightly.

"Are you alright?"

Of course, I also looked at Lin Mu, and I also saw that Lin Mu was holding his injured foot and gritting his teeth.

However, at the same time as Lin Mu gritted his teeth, his eyes followed the ground of the books he had just kicked into.

"Grass ......"

I felt a pang in my heart, and I couldn't help but widen my eyes as I looked at the same.

Because I only saw that as Lin Mu kicked those messy books, a big hole appeared in the ground under the books!

Yes! A big hole! It looks like it should be just enough for an adult to come in and out!

Surprised, Shen Li also surrounded him, squatted down and looked into the big hole.

Seeing this, of course, I also stepped to Shen Li's side, and also looked at the big hole.

However, at a glance, I couldn't help frowning, for I had only seen one bead in the big hole......

Not bad! There are potholes in this big hole, which is obviously not an underground fortification project, otherwise it would not be so rough in construction, but more like it was made out of something, such as a large adult master. Big rats.

And in the midst of this big hole, in a dark scene, there was a round bead glowing with blue light, which fell in the depths of this big hole.

"What's the situation? Jewel? ”

I turned my head to look at Shen Li, Shen Li also shook his head, and at this moment, Lin Mu, who was coming around, stared at the big hole again.

"Whatever it was, the figure that came in must have entered this big hole, otherwise it would not have disappeared in this room."

I listened, of course I understood what Lin Mu meant, he was about to enter this big hole, because none of us could say for sure whether the figure that flashed into this room just now was Huiguo or not.

"Be careful, come up whenever something is wrong."

Shen Li stared at Lin Mu and said, Lin Mu also nodded, sat on the side of the big hole, and stretched his legs. If you go into a big hole, you have to slip. Into the hole.

However, just when Lin Mu was ready to slide. When I entered this cave, I stopped Lin Mu with a glare.

"What's wrong?"

Lin Mu looked at me and frowned.

"Something is wrong......"

I said, pointing to the hole.

"How did the beads in this hole become two?"

Yes! The blue beads that had only one in the big hole just now turned into two side by side......

Lin Mu was stunned, and Shen Li also leaned over to look at the big hole.

"Is there a ...... down there?"

Suddenly, before Shen Li finished speaking, the two blue beads in this big hole disappeared one after another......

Of course, this made me frown, and just for a moment, the two beads appeared again, and this time, of course, I also suddenly realized what these two beads were.

Grass! The two beads in this big hole are not beads at all, but a pair of eyeballs!

Yes! The two blue beads in this big hole are a pair of eyeballs!

Frightened, it was like pulling Lin Mu into the room, but at this moment, the two bead-like eyeballs in this big hole flickered, and a black shadow with a slender arm suddenly poked up and grabbed Lin Mushen directly. The feet that entered the cave suddenly dragged Lin Mu into the hole.

Grass!

I scolded in my heart, and I also took advantage of the situation, and grabbed Lin Mu's shoulder.

Of course, Shen Li also pounced, and also grabbed Lin Mu's other shoulder, and pulled Lin Mu with me like this, so that Lin Mu would not be dragged into the hole by the things in the big hole.

"Hold on!"

Stared at Lin Mu, and was shocked in my heart, because I only saw that Lin Mu's face had turned pale in this instant, but he kept clenching his teeth and didn't shout.

"It'...... It's powerful......"

Lin Mu almost spit out these words from between his teeth, and I also suddenly realized that the reason why Lin Mu's face was pale was because we were pulling with the thing below, tearing his body......

Of course, it was impossible for us to let go of that thing and take Lin Mu off the big hole, so I asked Shen Li to grab Lin Mu's shoulders, and then rolled and went to Lin Mu's back.

And Lin Mu was lying on the edge of the big hole, and there was of course a little gap in the big hole behind him.

I didn't think much about it, and put the black knife in my hand into the gap, and at the same time mobilized the burning in my heart. The hot breath is infused with the black knife.

For a while, scorching. The firelight brought by the hot breath illuminated the entire big hole, and I also saw in this firelight that the one pulling Lin Mu under the big hole was a humanoid creature with slender arms, and the face of this humanoid creature was like the face of a spider, with a pair of big pincers in its mouth, one by one, extremely terrifying......
