Yes, a loess road, and in the center of this loess road, there is also a track built, which should be used to transport the loess excavated from the loess cave at that time.

I glanced at it quickly, and fortunately, in this big loess hole, there are also dense ghostly insects floating, so that we can't see anything.

We didn't stay long, and after determining the general situation of the loess cave, we marched towards the front of the loess cave.

Leaning on the wall on the left side of the loess cave, it was neither fast nor slow, until in the process, a large rail bucket car gradually appeared on the track in the center of the loess hole.

Sure enough, as I had thought, this track was the tool used to transport the loess excavated from the loess cave...... Wait a minute!

My heart trembled suddenly, and I also stared at the transport bucket truck on the central track of the loess cave, because I only saw that the transport bucket truck on the central track of the loess cave was filled with a dark red block!

Yes! A dark red lump! It's like blood after it has clotted!

"Grass ......"

I couldn't help but curse, and Shen Li, who was on the side, directly reached out and touched the bucket cart, and rubbed the dark red lump in the bucket car.

"It's ...... Earth"

"What's that?"

My heart moved, and I reached out and picked up the dark red lump in the bucket cart.

Shen Li is right, it's not blood, if it's blood, this handful will definitely be powdered, and the feel of this dark red lump is obviously earth.

I really haven't seen the dark red earth like blood after it has coagulated......

"Grass, what did these little devils dig in this loess back then?"

Scolding in a low voice, he also looked at the front of the big loess cave, and his heart was uneasy and curious.

Of course, we didn't stop long, and after making sure that it was not blood in the bucket truck, but dark red soil, we continued to walk forward against the big loess hole.

Only this time, we found many skeletons pushing bucket carts, on both sides of the tracks of this loess cave.

The bucket carts pushed into the loess cave are empty, and the bucket carts pushed outside the loess cave are also full of blood-red clods, which shows that the little devils in the underground fortifications had an accident after excavating the blood-red clods.

Breathe deeply, but even the air inhaled is gloomy and cold, and with us moving forward, finally, after ten minutes, the scene in front of us is no longer a deep loess hole.

Yes! The scene in front of us is no longer a deep loess hole, but a dark red blood red!

Not bad! Dark red blood red! The depths of this big loess cave have completely turned into a blood-red hole, and the walls around it that should have been loess have completely turned into blood-red walls!

It's like a cave surrounded by blood, or every inch of the dirt in this cave has been soaked with blood!

He was completely stunned, and his heart couldn't stop trembling at all, while Shen Li, who was beside him, looked at the cave wall beside us with a calm face.

I also looked at Shen Li's line of sight, and I couldn't help but feel a sigh in my heart.

For I only saw that the wall of the cave beside us, where the loess joined the blood-red earth, was a straight line......

Yes! A straight line! Just like the Chu River and Han Realm in chess, one side of this line is loess, and the other side is blood-red soil!

The rules and regulations are not a little out of bounds, which shows that this is a junction......

"Look here......"

At this moment, Lin Mu beside him pointed to the other side of the cave, and then, Shen Li and I looked over one after another, and our hearts couldn't help but tremble.

Because I only saw that on the other side of the cave that Lin Mu pointed to, there was a thick wall on the 'line' that divided the loess and the blood-red soil......

Yes! A piece of wall, at least a meter thick, but only one corner was built, just enough to frame the blood-red cave wall on the other side of the loess.

"It was built by the little devils back then?

They noticed that something was wrong, so they wanted to build a red brick wall like the one in the previous underground fortifications, and plug the blood-red cave inside? ”

As I spoke, Shen Li shook his head decisively.

"Jiang Wusheng, if the little devil back then found something wrong and wanted to block the blood-colored cave on the other side of this loess, then how could he continue to dig this cave?"

I frowned when I heard it, but I had to admit that Shen Li's point of view was right.

Shen Li's point of view is of course right, the carts of the skeletons pushing the bucket cart towards the outside of the cave are all transporting the red soil of this blood-red cave, indicating that the little devil has been digging this blood-red cave......

But since this blood-red cave has been excavated, why build a wall at the junction of this blood-red cave and the loess cave to separate the two sides like the red brick wall in the previous underground fortifications?

Without waiting for me to think about it more, Lin Mu on the side opened his mouth in a low voice.

"This wall is not a ...... built up"

I was stunned when I heard this, and saw Lin Mu pointing uprightly to the wall at the junction of the blood-red cave and the loess cave on the side.

Of course, I looked along and couldn't help but feel a sigh in my heart.

For I only saw that the walls of the junction of the blood-red cave and the loess cave were full of traces of crumbling on the top and side edges.

But if it is a wall built of bricks one by one, how can it be damaged?

Therefore, as Lin Mu said, this wall was not built, but ...... Chiseled!

Yes! This wall was not built at zero hour after the little devils discovered the strangeness of the blood-red cave, but this wall was originally in this loess cave, isolating the blood-red cave on the other side of the loess cave!

It was the little devil who chiseled open this wall to enter the blood-red cave and continue to dig in the blood-red cave!

For a moment, my eyes were completely wide-eyed, because when I thought about it this way, this wall was actually a wall that had been buried deep in the depths of the cave!

I have seen in some of the countries that are at war every year, and in order to prevent the enemy from digging tunnels through the ground, those kingdoms will build walls under their own lands to defend the whole country.

Of course, this situation only exists in the middle, but the chiseled wall in front of us does exist......

"Remember the annotations on the map?"

At this moment, Shen Li took over and spoke.

"The other two underground fortifications marked on the map are 'forks', only this underground fortification is 'hook', maybe these three underground fortifications are all excavated, but those two underground fortifications did not dig what the little devil wanted back then, and this underground fortification was excavated to ......"

I nodded slightly, and let out a long breath of cold air.

"In other words, the little devils back then, digging deep in this evil cave, is this wall, or rather, the blood-red cave in the wall......"

"Not a cave......"

Shen Li shook his head again.

"Before the excavation of this blood-red cave, it was a piece of blood-red soil, the so-called cave, but the little devils dug out the cave back then, that is to say, what the little devils were digging and looking for was this blood-red area......"

I nodded again, and looked straight at the blood-red cave in the middle of the border.

The little devil came to the source of this evil cave to find this area of blood-red soil, so what is there in this area of blood-red soil that can make the little devil dig so much trouble back then?

And what happened to the blood-red cave dug by this little devil back then, so that those who dug the cave could die in an instant?

Of course, it is impossible to speculate, and all we can do is keep moving forward until the answer comes to mind.

Everything is strange in this evil hole...... The little devil at the beginning, the current Nanyang Yiren, secretly helped our black-robed people, and Huang Jue, who also entered this underground fortification with the Puliang puppet......

The answer to everything is in the depths of this blood-red cave, and the charm we are looking for is also in the depths of this blood-red cave according to the guidance of the Buddha card.

All this ...... Isn't it a coincidence......
