At the end of the road is a spherical stone room, there is a deep hole on the ground of the stone room, a stone step is inclined downward, Ye Ling did not take the liberty to go down, only stood in front of the stone steps and looked down. Wang Weihan and the others also leaned over and shone a flashlight at the bottom of the stone steps, but Han Daring used a flashlight to shine and paced in the stone room to observe.

I saw that the four walls of the stone chamber were smooth and very wide, and although the traces of excavation were slightly rough, they were much finer than the green jade gate. When the flashlight shines on, there is also a hidden blue light in the stone wall.

Han Daring said:

"It seems that from the Qingyu Gate through the Yongdao, until the stone room here, all are green jade veins, as if it is a hollowed-out super large green jade, here the air circulation is smooth, there must be a place for ventilation, if it is an ordinary stone cave, I am afraid that it has long been weathered seriously and even partially collapsed.

I think that only hard green jade can keep this place in its original appearance for thousands of years. ”

His voice was not very loud, but the sound echoed around the circular stone room, and it did not stop echoing for a long time.

Han Daring's flashlight shone on the stone wall, and saw that there seemed to be many patterns carved on the stone wall, but when he got closer, he saw that it was the immortal urns carved on the ancient artifact. These fairy baskets are finely carved, the hook is deep, far more than the Italian on the wall of the Yongdao, carved neatly and clearly, at a glance is carefully carved, not as sloppy as the Yongdao carving.

Han Daring observed in the cave for a while, then walked to the deep cave on the ground and observed the stone steps of the deep cave. He saw that the cave on the ground was deep and dark, and he couldn't help but think that since everyone entered the cave, they had been slowly descending along the way, and although they had climbed up from the narrow old waterway for a while, they could not offset much of the descending depth, and if they went down again, they didn't know where they would eventually lead!

He remembers when he was in school, he read a French book called "Journey to the Center of the Earth", which is written by the French science fiction scientist Verne, which tells the story of a German scientist who receives a coded letter and then takes his nephew to the center of the earth, where he witnesses many strange things and experiences many adventures.

At that time, he read this book just as a pastime, but he never imagined that he would have such a similar experience today.

Everyone hesitated slightly when they looked at the deep cave stone steps, Han Da'er was about to walk down the stone steps with his hands in hand, but Wang Weihan took the first step and walked down the stone steps.

Han Da'er followed, Mei Ruohong, Ye Ling and the others also followed down the stone steps, only the rice bucket twisted and stopped, and slowly rubbed to the edge of the cave, but they were afraid. Chen Feiyang didn't care about 3721, he bumped forward behind him, squeezed him and walked down the stone steps, and in the end, it was still Li Huan who broke off.

The stone steps extend downwards, and the walls of the cave on both sides and overhead are just over a man high, but the air circulation is unobstructed, so there should be more space below.

The crowd kept walking down, and it seemed as if there was no end to the steps. Speaking of which, although going down the stairs is easier than going up the stairs, it takes more knees than going up the stairs, and every time he goes down, his knees are hit by the weight of his body, plus he still has dozens of pounds of equipment on each of them.

After walking for an hour, Han Dada'er, Ye Ling, and Li Huan were not very good at martial arts, even if Chen Feiyang was the youngest and most energetic, his knees began to ache and he was sweating. And Mei Ruohong was panting, putting her hand on Han Da'er's shoulder, and her walking speed slowed down greatly. Wang Weihan moved his legs faster and slower, and sweat beaded down his forehead.

Among them, Fan Tong was the worst, he was sandwiched between Chen Feiyang and Li Huan, his footsteps were staggering and difficult, his whole body was already soaked with sweat, he couldn't advance or retreat, but he was struggling to support, and he was still shouting vigorously in his mouth, "Slow down, rest for a while and then go ......"

Han Daring touched the cave wall with his hand, and saw that the stone walls were uneven, and they were all coarse-grained rock walls. He saw that everyone was walking hard, so he wanted to say a few words to distract everyone's attention, so that he would feel a lot less effort when walking, so he said:

"The cave wall here is rough, it should not be a Qingyu vein for a long time, just an ordinary rock, otherwise if such a deep and long stone step is carved on Qingyu, I am afraid that it will be difficult to do it even with the power of the whole country!"

Mei Ruohong gasped and said:

"I remember Tianjin Wei, which is at the junction of the zonal structure and the Neo-Huaxia tectonic system, is a Cambrian formation, with granite and associated granodiorite in the depths, and the hardness is as high as it stands to reason.

Looking at the stone wall, it may be granodiorite, which contains mainly plagioclase and dark minerals, including amphibole and some black mica, so it is slightly less hard. ”

Han Da'er smiled and said:

"I thought you were only proficient in physical chemistry, but I didn't think you even knew geology, and you were really knowledgeable!"

Mei Ruohong listened to a few words of praise, but the expression on her face was still the same, but she had a tired look.

Everyone walked a short distance, and sure enough, they saw that layers of dark crystalline stones-biotite began to grow on the stone wall.

Wang Weihan touched the biotite on the cave wall with his hand and said:

"This thing looks a lot like crystal!"

Fan Tong, who was out of breath, walked against the wall, but suddenly let out a "Wow!" "A bang.

It turned out that he was holding on to the rock wall, but he was scratched by something on the rock wall, thinking that it was scratched by mica, but Chen Feiyang used a flashlight to shine it, but it turned out to be some sharp shell fossils.

Fan Tongyi pouted his hands and scolded:

"! How can there be broken clam shells under the ground? ”

梅若洪 says:

"The Cambrian is the first paleontological lineage, 570 million years ago, and the Cambrian is rich in fossils in the strata, and it is not new to have shell fossils."

Fan Tong didn't understand what Mei Ruohong meant, but just muttered and scolded his mother.

Han Dada'er used a flashlight to shine on the cave wall and said:

"In ancient times, the Tianjin area should have been the sea! I remember reading books in the past, saying that there seemed to be three or four shell embankments in Tianjin, and in ancient times, this land should have been soaked in the sea, and this place in Tianjin was only available after the sea was returned to the land. ”

The further down they went, the more mica there was on the cave walls, and later clusters of spars grew on the stone steps beneath their feet, but not like the mica on the cave walls. These hedrons are dark in color, and when illuminated with a flashlight, they emit a faint blue glow.

Han Daring said:

"Earlier, in order to solve some evil cases under the guise of ghosts and gods, I read a lot of books that touched on the analogy. I once saw it in an ancient book of monsters, similar to the description of this hedrome.

In the book, this kind of spar is called "stone crystal"!

But this kind of stone crystal is not the same as the "stone essence" mentioned in "Huainanzi" and "Seven Notes of Yunji". That kind of stone spirit refers to iron ore, and the blue stone crystal in front of him is described in the book as a revenant crystal that grows in front of the gate of Hades.

But I don't believe in the underworld or anything like that, it's just the imagination of strange forces! ”

Wang Weihan also shone the stone crystal with a flashlight, and then said:

"In Japan before, I went to explore caves with my friends, and I also saw some spars and mica growing underground, but I have never seen anything like this. It's more in line with what you said about the Hell Crystal! ”

Fan Tong gasped and said:

"Shall we ...... Should...... I don't care if I get some back...... The legends of the underworld are all fake anyway...... Anyway, no one has seen it, and it's enough for us to blow it out...... The price is ...... at that time The price is as you like! ”

As he spoke, he started to chisel the stone crystal with a short shovel, and Han Daring couldn't stop it.

Just listening to the sound of "dangchang", the short shovel in Fan Tong's hand was unexpectedly broken apart, which shocked him to numb, but Shi Jing was only slightly missing, and there was not even a crack.

Fan Tong's palms ached, he couldn't stop trembling, and opened his mouth to scold:

"Dog's day! How is it so hard with pig iron! ”

Li Huan was almost hit by the broken shovel just now, but fortunately he flashed his head sideways and reached out to catch the shovel.

Chen Feiyang sneered:

"I eat so much, I don't have any strength at all, I can't even hold a shovel! Can this thing still have pig iron hard? ”

Fan Tong ignored him, took the short shovel from Li Huan's hand, this time held the short shovel with both hands, and slowly chiseled it down towards the hole in the spar, and only got a small piece the size of his thumb for a long time. He was tired enough to go down the steps, but now he was even more sweaty when he was digging all the way down.

Han Daring looked at the hole in the ground, although it was very deep, but the air circulation was smooth, or he would have been busy with Fan Tong's work, and now he would have fainted from severe hypoxia suffocation, thinking that there must be some vast place connected here.

Fan Tong was tapping on the stone crystal, and Mei Ruohong was also quite curious about this kind of stone crystal, and wanted to take some as a specimen to bring back. I also used a short shovel to slowly knock a spar, but the spar was very hard and it was not easy to chisel.

Ye Ling has always been interested in strange things, and when he was a snitch, he went to thousands of households, and he just took some rare things, and returned them as they were when he got tired of playing. At this time, seeing that this blue stone crystal was strange, he also took out a sharp blade on his body and helped Mei Ruohong to chisel the stone crystal.

Everyone just took the opportunity to take a break, only Wang Weihan didn't care about us going down, and soon he couldn't even hear his limping and intermittent footsteps. Mei Ruohong and Ye Ling were busy for a while before they took out two copper-sized stone crystals and put them in their bags.

Han Da'er wanted to sit down and rest, but when he saw Wang Weihan continuing to go down, he got up and followed him on. Mei Ruohong and Ye Ling had already taken samples of Shi Jing, and they also continued to descend with Han Da'er. Li Huan and Che Feiyang dragged and pulled up the rice tong who had just finished taking the stone crystal and was panting with the dog, and then the few people in front continued to walk down the stone steps.

It didn't take long for Han Daring and several others to catch up with Wang Weihan one after another.

Although Wang Weihan wore a cushion brace on his leg, after all, he had an old disease in his leg, and he was very tired along the way, so he had already walked slower and slower, almost at a turtle speed.

After a few people caught up with Wang Weihan, they walked for another two hours, and finally Fan Tongyi sat on the ground with his buttocks, panting breathlessly, his clothes were soaked with sweat, and he was fished out of the water, and there was a smell of sweat.

He waved his hands together, and said in his mouth:

"No more...... Again...... If you don't stop for a while, I'll ...... first Homecoming! ”

Saying that, from untying the kettle, it was a wild pour. After three sips, he drank a trickle of nothing, and after drinking, he looked at Chen Feiyang's kettle and swallowed his saliva.

Chen Feiyang pretended not to see it, but Li Huan untied his kettle and handed it to Fan Tong, who poured it again and drank most of the pot before stopping. simply lay down on the stone steps to rest, regardless of the discomfort of the stone steps.

"Be careful to lie down and have a stroke, but you will never get up again!"

Chen Feiyang also felt tired and panting, and he didn't forget to mock his demeanor.

Fan Tong took out two baked cakes and stuffed them into his mouth, and said back:

"Tube...... I can't do it, you... For my fleshy ...... Try it, it's already tired! ”

Chen Feiyang said:

"Then you still eat!"

Fan Tong didn't pay attention to him anymore, just crooked to the side to eat the baked cakes, and he didn't know where he got so much to eat, in addition to the dry food supplies given by Wang Weihan, he even brought so many baked cakes, as if he was eating and racing.

Han Daring saw that everyone was tired, he had the best physical strength among these people, but he had suffered internal injuries before and had not yet healed, and at this time, he was also sleepy and weak all the way.

Everyone rested on the spot for a while, Wang Weihan took the lead in getting up, and actually bypassed everyone and walked down the steps first. Among all of them, he was the only one who was most eager to see the true face of the lost ancient city, and he suddenly gave birth to a lot of strength.

The stone steps of this cave are not very dangerous anyway, Wang Weihan's steps are very slow, Han Da'er simply still sits and rests, and continues to walk as if he were himself.

Unexpectedly, it didn't take long for Wang Weihan to shout at them to come down quickly.

Han Daring thought that something was in danger of him, so he quickly got up and ran down. After turning a corner, I saw Wang Weihan standing on the side of the stone steps, flashlight, and shining it towards his feet.

When Wang Weihan saw Han Daring coming, he hurriedly turned around and beckoned:

"Look here!"

Then the flashlight shines forward and downward. The flashlight is limited, and where Wang Weihan's combat power is seen, a few stone steps further along, there is darkness.

Han Daring just walked over, suddenly felt a strong wind blowing on his face, and after a closer look, he realized that the stone steps had come to an end, and in front of him was a huge hemispherical stone chamber, about ten meters wide and narrow, the strangest thing was that there was no ground in this stone chamber, and below it was a straight and deep hole, like a fierce beast with a huge mouth, wanting to devour the people who were walking down......
