"Congratulations to your master, you and the unicorn bone are perfectly fused, even more perfect than my father and I imagined," Zhang Zhiyan said excitedly.

I looked at my hands with a shudder, and my nails were already growing... Zombie-like nails!

All this is premeditated, as Zhang Zhiyan said, I am a guinea pig, and the experimental effect is even more perfect than imagined.

I don't know if the Sun-Covering Daoist is monitoring Zhang Zhiyan all the time, every word and every action we say is under the control of the Sun-Covering Daoist, and even, every moment, Zhang Zhiyan is communicating with the Sun-Covering Daoist, and I have no privacy at all with Bai Mei, Three-Tailed Jinjia and Liu Ruyun.

Just as I was about to drill into the crypt tunnel that Zhang Zhiyan had opened up for me, Liu Ruyun shouted loudly in the space ring: "Childe, you can't enter." ”

I was stunned, frowned, and stopped.

"Childe, I just got up to the hexagram, it's extremely dangerous down here, you go down, nine deaths," Liu Ruyun said in shock.

I sneered, let out a long breath, and plunged headlong into the crypt and cave, if Liu Ruyun didn't tell me this, I would still hesitate, listening to her say this, I don't have anything to think about anymore, yes! I want to die, and it's better to die than to be someone else's puppet.

On another level, everything is Liu Ruyun's fault, if it weren't for her trust in Zhang Zhiyan, I wouldn't have ended up in today's field! Become a walking corpse.

Seeing that I was determined to throw myself into the pit, Liu Ruyun sighed lightly and hugged her knees sadly, she seemed to understand what I meant, and lowered her head with self-blame.

The vast underground pit, at this time... I feel that the surrounding walls are like foam, as long as I get close, immediately avoid the way, the original so-called retreat is such a situation, before I wondered, a huge coffin, how can it be strictly underground drilling hundreds of thousands of kilometers.

In the vast layer of soil, in addition to the dead branches, rotten leaves, stubborn stones and dry bones, there are pits of animals and insects and ants, nothing unusual, however, drilling and drilling, in the hole in front of me, I actually found... Something strange exists.

A huge black beetle, the size of an iron pot lid, crawled quickly in the hole, because the earth element avoided me, it fell out of the halfway cross-sectional hole, its limbs and legs danced desperately to the sky, and its yellow belly was very disgusting to look at.

I thought it was a turtle or a mutated bug, but when I looked closely, my body jerked violently, and I took two steps back, how could the head of this insect be embedded in the head of a living person!

It is absolutely impossible to be a natural species, that the face is characteristic of the morphology, and obviously has a systematically complete endoskeleton, which... This is not an ordinary bug, it is a bug that has become a sperm!

However, to my surprise, this guy didn't have any demonic spirit at all. It's exactly... Real creatures.

The thing couldn't see me, Zhang Zhiyan had already made me invisible, and after rolling on the ground, it burrowed back into the cross-sectional tunnel, and then continued to crawl forward.

"What is this?" I asked Bai Mei in surprise.

Bai Mei said: "It feels... It's like a combination of humans and bugs, but it's not a demon, it's a real creature, and I've never seen such a strange existence. ”

"Could it be that the underground cracks on the Qinghai-Tibet Plateau extend all the way to Siberia? That's an exaggeration," I exclaimed.

"Hehe," Zhang Zhiyan said with a smile, "I know what's going on, this is the sappers of the Black Mother, the disciples of the Maxian Gang who made mistakes." ”

"What... What? "I'm buzzing in my head, disciples who have made mistakes?

Zhang Zhiyan coughed lightly and explained: "The black mother has great powers, casting spells to degenerate people and turn them into insects, and then move bricks to build the underground Great Wall, let's soon reach the inner city wall." ”

I listened dumbfounded, people degenerate and become bugs? What is the Underground Great Wall?

"The current national boundary is only stipulated by the imperial court, but it does not stipulate the ownership of the rivers and lakes, this land boundary used to belong to China, in the eyes of the black mother, it will always be Huaxia, she built the underground Great Wall to resist the invasion of the demons of the snowfield," Zhang Zhiyan said.

Then she told us some strange things.

As a god who guards the northeast, the black mother can far more than the three eastern provinces, the entire eastern Siberia is the sphere of influence of the black mother, where the territory is vast, there are many animals and plants, and there are many monsters who become monsters, and the black mother guards the east to resist foreign demons.

In addition, there are many believers who worship the Black Mother as a righteous god, including the Northeast Horse Immortal Gang, the Siberian Shamanic Organization, and the Tunguska nomads, and the ones we see in the underground world are just the tip of the iceberg.

Disobedient believers, or people who look unhappy with the black mother, will be cast and degenerated into monsters, without demon magic, but with strong power adaptability, used to complete some special tasks or build fortifications.

Incredibly, the underground world we entered at the beginning of the Tibetan Plateau was far from being only a few hundred thousand square kilometers as imagined, and it stretched comprehensively, with crevices and fissures stretching from Qinghai-Tibet all the way through the Mongolian Plateau to Siberia.

"You now know why you see death worms in the underworld, because the entire Qinghai-Tibet Plateau, the Mongolian Plateau, and the Siberian Mountains are completely connected in the underworld," Zhang said.

I was horrified! The information that Zhang Zhiyan has far exceeded my imagination, these things are unheard of by me, and Liu Ruyun does not know these things.

"The boundaries of this world are not as simple as the borders on the map, and it would be too superficial to understand it that way, in fact... The human world is a big existence, and what we call going to the underworld is just crossing another dimension," Zhang Zhiyan said.

At this time, Liu Ruyun in the space ring also responded: "What Zhi Yan said is right, the entire underground has a depth of thousands of kilometers, in fact, it belongs to the yang world, and the current technology is only less than 10 kilometers deep. ”

Hearing that Liu Ruyun also regarded Zhang Zhiyan as a teammate, I also felt a little disgusted with her in my heart, this guy thought we were in an underground labyrinth, and forgot that Zhang Zhiyan was a poisonous snake!

Zhang Zhiyan coughed lightly and continued: "Mother Hei is building the underground Great Wall, and there are more degraded laborers here, including disobedient disciples, as well as Russian old Maozi, and Japanese. ”

"But......" I clicked, "Shouldn't man degenerate into an orangutan or a monkey?" How did it degenerate into a bug? ”

Zhang Zhiyan smiled: "What's so strange about this, aren't orangutans and monkeys also evolved from bugs in the first place?" If you say the most primitive, it should be a fish, Master, you think, the big insect just now, just now, the body has degenerated, but isn't the facial features still human? The skull is embedded in it, which means... The black mother is only part of the tissues and organs that let the other party degenerate, but it still retains the human mind, in fact... To some extent, it cannot be regarded as degradation, and adaptation to the underground environment can also be understood as evolution. ”

"Why does Daddy want to give you the unicorn bone, it's because I'm afraid that you will fall into the black mother's demon method, and if you become a big insect like Jin Jia, it will be a joke," Zhang Zhiyan said hehehe.

When Jin Jia heard Zhang Zhiyan say this about himself in the space ring, he scolded angrily: "Slut! ”

In the face of Jin Jia's insults, Zhang Zhiyan was unimpressed, and continued to smile and said, "Master, it seems that we have arrived near the construction site of the underground Great Wall. ”

Hate is hate, but Zhang Zhiyan's words are worth my deep thought. The Underground Great Wall? What kind of existence is this?

If you want to keep out evil spirits, there's no need to build the Great Wall underground. And this Baikal, a long strip with a huge area, looks like a shielding belt.

I don't know anything about geography, this long and narrow Baikal Lake, the area equivalent to Gansu Province, is the largest freshwater lake in the world, and the black mother's actions are very intriguing to choose their nest at the bottom of Lake Baikal.

"Zhiyan, what else do you know about Black Mother?" I asked curiously.

Zhang Zhiyan shook her head: "No more... I don't know, anyway, Daddy asked me to remind you to be more careful in everything, and try not to be tough if you can outwit. ”

I laughed bitterly at myself, how could the people of the Sun-Covering Dao still have such kindness to remind me? I'm afraid it's Zhang Zhiyan's own words, this cunning woman.

We continued to walk forward, peeling away the underground worm passages of the cross-section layer by layer, and found more monsters that combined with humans and worms, and the further down we went, it seemed that the worm passages in the leylines became denser.

It feels like entering an ant hole, these monsters that are combined with insects are really like what Zhang Zhiyan said, there are yellow people and white people, there is no distinction between men and women, young and old, just from the facial features can be distinguished. Faintly... I feel that this black mother is the devil in hell, a living person, why did you turn him into such a pitiful appearance, and the number is staggering, we can meet one every ten meters.

Moreover, these victims, in addition to the turtle-like beetles, also worms, crickets, all sorts, if it weren't for the facial features of human contours, I really thought... It's back in the underground world of the Tibetan Plateau.

We continue to dig down, the depth of Lake Baikal is more than 800 meters, we drill down from the top of the mountain, at least 2-3 kilometers to reach the periphery of the Black Mother Underground Palace, anyway, it is not difficult to open the road with the power of controlling the soil, I actually want to see, what is the so-called underground Great Wall like?

PS: It's a little busy today, it's estimated that there is only one shift, if it hasn't been updated at 8 o'clock in the evening, it is estimated that I will work overtime~
