It is common sense that the further down we go, the more solid the formation should be, but the opposite is true, the further we drill, the sparse soil is almost like cotton wool.

What's even more incredible is that these insects in the transition are also of different sizes, the big ones are like iron pots, and the small ones are like water scoops, but the outline of the human face can be seen. The beetle with a big scoop of water, with a human face as small as a dead man in a witchcraft bottle in the Amazon jungle, is really hard to imagine how the black mother degraded them.

There was a loud "boom", the stratum under my feet collapsed, my body sank suddenly, and I quickly stabilized my body with the power of imperial qi, and hundreds of tons of boulders fell down from the ground to the ground.

Although it was a false alarm, when I saw the scene below, I was stunned and hovered in the "void".

But below, there is an existence similar to the underground world of the Qinghai-Tibet Plateau, but it is much larger and taller than that, and we hang on the rock formation of the sky, and see a huge, towering pyramid!

The scale of this pyramid is so large that the pyramid of Khufu in Egypt is so large that the spire almost touches the dome hundreds of meters high! The snake-like "Great Wall" encloses the pyramid layer by layer, this is the inner city, and the outer city runs through the entire underground world like the pyramid of Badaling, and there is no edge in sight!

"Looks like we're in luck! It just got to the top of the Black Mother's Palace," Zhang Zhiyan said excitedly.

"...... at the top of the Black Mother's Palace?" I sighed and marveled, could it be that what hangs above our heads is Lake Baikal tens of thousands of square kilometers? I rub! I was drilling hard underground, but I didn't expect... It's already run to the core.

Bai Mei sneered: "Where is this palace?" It's clearly an altar, and the real Black Mother Palace is still far away, you see, this altar is not yet finished. ”

She was right, the huge pyramid was still under construction, and countless "wormmen" crawled around on it, like a kingdom of cockroaches. On the vast earth, a pair of "beetles" carrying huge stone slabs slowly moved and transported them to the pyramid altar.

At first, I thought that whether it was the underground Great Wall or the pyramid altar, it was all built by these insects carrying bricks and stones, but on closer inspection, this was not entirely the case, these insects, one by one, climbed to the top of the pyramid, sprayed some paste-like mud on the wall, and then smeared the limbs and legs evenly, and the pulp was evenly coated into a skin, and after the air dried, the worm-like worm-like worm man squirmed up, spraying corrosive liquid with mouthparts, outlining the pattern on the wall like a carving.

I now understand why the insects I saw at the beginning were just pot-bellied, but I didn't see any bricks and stones on them.

"Wandering, what does this pyramid seem to suppress? It was very useful for the Black Mother to build this altar," Bai Mei said.

I let out a sigh of relief: "You all live, this black mother is a righteous god, but I feel... She's not a good kind at all, you look at so many bugs, how many people are degraded by this, it's no different from the demons in hell. ”

Bai Mei said: "I sensed that not all of these insects are degenerate, and many of them are derived. ”

"Derivative?"

"That's right, if you look closely, those small ones are the vast majority, they are not fully developed, and these bugs, the offspring and grandchildren that should continue to reproduce by degenerate people, are already the same as real bugs," Bai Mei explained.

Originally, she didn't say that, I was still disgusting, but now I am even more disgusting, and the underground world of the black mother is a cockroach nest, and a few unlucky degenerate people continue to multiply, divide cells, and produce countless slave laborers for the black mother.

"The saints are unkind, and they regard all things as dogs, so let's not jump to conclusions until we know the truth, these insects are very low-level, and we can just dive into the pyramid to find out," Bai Mei said.

"But... We're here to find the Rakshasa bones," I sighed.

Bai Mei smiled: "I feel that the black mother seized the Rakshasa bone blade, and this big pyramid is inextricably linked, we know that the other side can not be defeated, and, how do you know that the Rakshasa bone blade is not in this pyramid?" Didn't you notice that this pyramid is very similar to the one we saw in the corpse world? ”

"You mean? The black mother seized the Rakshasa bone blade to seal it? I was taken aback.

"It's hard to say, let's go in and see," Bai Mei said.

My heart sank, if the black mother really wanted to seal the Rakshasa Bone Sword, then if we took it again, wouldn't it be afraid that the world would not be chaotic? In that case, I would be a real villain.

Now I am held in the palm of my hand by the Covering Sun Daoist, even if he asks me to do something hurtful, I have no way, thinking of this, my heart is hesitant and sad.

With the Silver Fox's stealth and the ability to fly with air, it was not too easy to sneak into the inside of the pyramid, and I landed on the top of the pyramid that had not yet been repaired, and slowly drilled into it along a construction passage.

The walls of this corridor are scattered with masonry, obviously not even half of them have been renovated, and there are large and small insects crawling around everywhere, in this dense situation, it is really difficult to hide. Although Zhang Zhiyan's illusion can be invisible, the insects will still retreat when they touch our real bodies, their IQ is extremely low, and they are not aware of the entry of intruders.

However, the corrosive liquid in the horrible mouthparts still made me feel palpitations, for fear that the one would accidentally spit on me.

"Master, don't worry, you are now a unicorn, and this ordinary insect can't hurt you," Zhang Zhiyan reminded.

I stepped on the edge of the area and walked cautiously inside, looking at this group of dense bugs, I had a dense phobia again, my head was a little dizzy, I really wanted to spew out an electric lightning and fire thunder, and burn all these bugs into powder!

After walking a little further, the road surface began to slope horizontally, seemingly... The road is not for people at all, and this almost 30-degree slope of the pavement is completely out of line with the common sense of architecture.

The construction and intention of this pyramid itself is a mystery, if it is used as a magic circle to seal the Rakshasa Bone Sword, I can't see the doorway inside, it seems to be much more complicated than the Dead Sea pyramid summoned by Hong Jiutian, and the interior is comprehensive, like a labyrinth.

What's even more incredible is that on the sloping walls, it turned out to be... And a mirror!

"I'll go! How can there be mirrors here? I was taken aback.

"Little brother be careful, these mirrors can't keep the demon magic together," Sanwei reminded nervously, and I stepped back sharply, I was thinking, maybe these mirrors can break Zhang Zhiyan's stealth technique?

There are more mirrors in the corridor ahead, one after another, which simply constitutes a mysterious and strange world.

Bai Mei thought and whispered: "These mirrors are very similar to the visitation mirrors in a submarine, and at the innermost point of the pyramid, you can observe the outside world. ”

"It's a bit nonsensical to look at the outside world with a mirror," I sighed.

Zhang Zhiyan also frowned in confusion: "What this sister said is very reasonable, but using this way to spy on the outside world ...... It doesn't seem to make sense, not to mention the limited perspective, and with the mana of the black mother, it's completely unnecessary. ”

Bai Mei said: "Anyway, let's go and take a look first, don't worry if there is no demon magic on these mirrors." ”

Hearing Bai Mei say this, my nervous heart relaxed slightly, and I continued to walk forward, and sure enough, my figure was not reflected in these mirrors.

"It's so weird, we seem to be in a place we shouldn't be in, you see, there's not a single bug in there," I said, swallowing and foaming.

Bai Mei said: "There are many corridors on the spire of this pyramid, and we have only entered one of them, and if we want to know the real use, we can only go to the deepest depths. ”

At this time, Liu Ruyun spoke: "I feel... This... It's kind of like a condenser. ”

"What? Condenser? "My mouth opened in disbelief.

"Yes! Concentrator, this is a magic circle, I deduced the pattern of the distribution of the corridor just after I came in, and then according to the specific situation inside, I can draw a clear conclusion that this is a magic circle of concentrating light," Liu Ruyun said.

Bai Mei frowned and pondered: "Impossible, how can there be light here?" If we all have the ability to see at night, let alone inside the pyramid, even outside the pyramid, we can't see anything. ”

"I don't know about this, but the results of the deduction tell me that this Dao Dao is to receive the sun's rays," Liu Ruyun explained.

She said that we are even more confused, to take on the rays of the sun? Isn't that? This is an underground world 5-6 km deep, not to mention sunlight, there is no visible light!

"Master, let's go on, all the secrets will be known at the end," Zhang Zhiyan said.

I continued to push forward, taking every step carefully, for fear of smashing the mirrors on the "ground" and revealing the horse's feet.

The situation seems to be really as Liu Ruyun said, this mirror, whether it is from the angle of placement or the shape of the mirror itself, is to enhance the refraction of light, and this mirror is extremely transparent, I stepped on it...... Left behind a "shocking" footprint.

At the center of the pyramid, down is a loophole-shaped, mirror-made circular hole, like a crystal palace of scales. I was shocked when I looked down! But in the light and shadow reflected in the mirror, the hall under the pyramid was densely packed with people!

Among them are the people of the Northeast Maxian Gang, and... A bunch of foreigners!
