Shen Yuan and An Jia Ershao and his party cautiously and slowly approached the entrance of the cave where Ava and the others were standing, and after watching for a while, they turned off the flashlight in their hands one after another. As the flashlight beam disappeared, a green faint light shimmered from the hole three or four meters square!

The shimmer is dark green, not intense, and it appears strangely at the entrance of the cave, making people feel a little creepy! Ava looked back at the guide and asked loudly, "You are the only one here who has entered the Heavenly Ghost City, what is the matter with this light?" Is it safe? ”

The guide replied, "As long as those who have drunk the ghost grass soup are safe here, the rest is to pass through the heavenly ghost city." The Heavenly Ghost City has not been controlled by our ghost cave clan for many years、、、 I don't dare to stay, and I will lead the way after entering. Let's hope we'll be lucky enough to make it to the entrance of the Celestial Ghost Cave alive、、、、、、"

Everyone looked at the second young man of the An family, and the second young man of the An family looked at the green and quiet cave with interest, and said: "Of course, this is the territory of your clan, and everything is up to you!" Let me reiterate, the An family only wants the contents of the Heavenly Ghost Cave! Everyone、、、 all of you are not enemies of the An family! As long as you cooperate、、、 you will be grateful to settle down! Now、、、 Ava and my men protect the guide in front and go! ”

Although everyone was mentally prepared, when everyone passed through the ordinary cave door, they still stood collectively on top of a vast stone platform!

In front of me is a huge space that is miles square! Everyone immediately looked around for the source of the strange green light, but what they never expected was that this was a vast underground lake! The top of the cave is dark, I can't see clearly, I don't know how high! And the tranquil mirror-like surface of the lake turned out to be the source of green light!

The guide took a few steps forward, slightly fascinated by the top-secret place that his ancestors had guarded, and gently bent down to pick up an ordinary stone. Several black-clothed men beside the second son immediately raised their weapons and watched his movements deadly! The second son raised his hand and signaled that they didn't need to be too nervous.

In front of everyone, the guide waved his arm and threw the ordinary stone into the tranquil green lake below the platform, which was as green as a peerless jade. Everyone's eyes rolled along with the ordinary stone and smashed into the beautiful but strange lake!

The sound of "、、、、、、" stones entering the water indicates that the depth of this green water is not small, and the splash is not large. A circle of ripples has just spread、、、 and the mutation has suddenly changed!

This stone is like turning on a hidden switch hidden in the water, lighting countless invisible little light bulbs hidden in the water! The entire lake starts from the place where the stones fall into the water, and the originally dark green light instantly becomes stronger!

The green light spreads rapidly from the inside of the lake to the outside until it lights up the entire surface of the lake for miles in radius! Then there is the slightly smooth stone wall around it, and the stone wall also shows mottled green light spots, spreading all the way up!

"It's amazing! Is this a glowing algae? How do they survive in the underground at a depth of tens of meters and hundreds of meters? An Jia's second young man muttered.

The short black-clothed man beside An Jia Ershao carefully looked at a micromonitor on his wrist and said softly: "Unknown algal moss amphibiotes, the radiation dose is slightly exceeded, but it is basically no harm to the human body, and the environment here is quite safe." ”

Just as everyone was looking at the strange dream-like terrain around them, Shen Yuan suddenly noticed that the guide standing at the front was looking up at the top of his head!

Shen Yuan followed his gaze and looked hard, and his eyesight beyond ordinary people immediately made him almost cry out! As the mottled light spots and moss on the cave wall were lit up all the way、、、、、、 the originally black and swarthy cave roof slowly revealed a trace of shape at this time!

"OMG! Is that 、、、、、、 a city? How is it upside down? A man in black noticed the strangeness on the roof of the cave and shouted out!

Everyone raised their heads and looked up at the top of the cave、、、、、、 only to see that the mottled spots of light had now illuminated all the space of this vast underground lake! A city several miles in circumference was inlaid on the roof of the cave as if it had been turned upside down!

The city seems to be all carved with stones, and it is so naturally embedded on the roof of the cave! As the faint green light gradually intensified, several stalagmite-like pillars with a diameter of more than ten meters could be seen hanging down from the interior of the upside-down city, seemingly connected to the bottom of the lake. It should have also played a supporting role、、、、、、

The second young man of the An family walked to the guide who was still looking at the Heavenly Ghost City in a daze, and said softly while looking at the underground city that the ghosts and gods were going to marvel at: "This is the Heavenly Ghost City? It's remarkable! How was it made? Your ancestors are great、、、、、、"

The excitement in the guide's eyes faded, and he replied in a hoarse voice, "You think too much, this city is much older than the history of our ghost cave clan. It wasn't built by us, and no one in the world seems to have such great power to build it! We're just a group of janitors of its choosing、、、、、、"

"Don't you know who built it? Isn't there any record? The second young man of the An family still asked without giving up.

The guide shook his head: "Maybe my ancestors knew! It's been too long, too many weird and tragic things have happened, and this secret has died out with the decline of the Ghost Cave Clan. I'm just as curious as you are! Curious about who built such a magical Heavenly Ghost City outside the Heavenly Ghost Cave in the first place, and curious why they chose us to be the guide and guardian here! Oh、、、、、、 it's a pity, we can't find the answer. Maybe 、、、、、、"

An Jia's second young man frowned: "Maybe what?" ”

The guide turned his head sideways and smiled weirdly: "Maybe you can get all the answers when you enter the depths of the Heavenly Ghost Cave!" ”

The second young man of the An family looked at the last guide of the ghost cave clan with a complicated expression, thought for a long time, and said softly: "I don't believe in any gods and ghosts, I only believe in wisdom and strength!" It's magical, but it's not so weird that it scares me! It's also a ruin built by man, and if you're not mistaken, it should have been carved out of the stalactites and stalagmites hanging down from the top of the cave! It also had to rely on the support of the largest grounded stalagmites to reinforce.

So, don't think too much about it, if the city is floating in the air! Then I don't dare to come back without saying a word, then it's not a realm that humans should touch now! For now、、、、、、 lead the way! I'm curious how you've come to this city over the years! ”

The guide smiled and slowly walked to the front of a raised square stone block in front of the stone platform, and the four camouflage uniforms behind the hall and everyone slowly moved forward with the guide, carefully watching every movement of the guide.

The guide rubbed the smooth stone, and Shen Yuan noticed that the stone was shallowly carved with dense ornamentation, or characters! At least Shen Yuan couldn't see what it was, the whole stone was dull and dark. It is not infested by the algae that seem to be ubiquitous, emitting a mottled green light.

The guide stretched out a left hand, and then used the yellow, sharp nail of his right index finger to cut deeply in the left palm, and he himself cut a wound on the palm of his left hand. I don't know what's going on.、The blood flows out very slowly.,Under the dark green light.、The color of the blood seems to be abnormal.。 The guide slowly pressed his left hand to a palm-sized pit at the top of the stone, and gently pressed it!

Everyone watched the movements of the guide and waited quietly. After a full two minutes, everyone was still motionless looking at the guide standing there. Suddenly, a slight but clear sound of clashing sounded on the Heavenly Ghost City, which was two hundred meters high above the roof of the cave!

Shen Yuan used his spiritual power to look at the top of his head, and slowly, he saw several entangled chains as thick as an arm slowly falling from a dark place in the Heavenly Ghost City. The landing point is exactly where everyone is!

Everyone watched as this strange set of chains slowly fell, until they fell to the position behind the guide, and the second young man of the An family glanced at the black-clothed man beside him! The man in black immediately turned around and got a few flashlights from the others, and then easily assembled them together, adjusted them, and then lit them again, only to see a pillar of light that was several times brighter and thicker than a single flashlight shone out, pointing straight at the position where the chain fell out!

Shen Yuan and Dao Zai saw that it was really interesting to settle down with this family, the equipment on these subordinates was strange and obviously much more advanced than the outside world, not to mention anything else, as soon as they entered this stone cave. The black-clothed man next to An Jia Er Shao is constantly using that equipment to detect the surrounding environment, what air composition, air pressure, depth, location, radiation index are messy, and he will communicate with this An Jia Er Shao every once in a while.

There are also masks they are equipped with, except for the dead Duerji and An Jia Ershao, they are basically a pair of hands. Shen Yuan believed that even if they only turned on a tactical flashlight, with this helmet that looked full of technology, they could still have powerful night vision, as well as the one-piece tactical backpack and weapons that they had never seen before! said that they were future soldiers, and Shen Yuan believed it.

Seeing the man in black vigilantly searching for the place where the chain was falling, the guide sneered, and said, "Don't look for it, no one is up there." The chain is wound around a horizontal copper shaft that sits between two inverted statues, which are fixed directly inside the cave wall. As for why it moves, and how it recognizes the blood of our ghost cave clan, no one knows. Interested in you guys going up in research! Unfortunately, it turned out that it was said that there was a gold hanging basket attached to the bottom of the chain, and I don't know when it was destroyed.

What do you guys think? If you are dragged up by chains, you can only catch four people, and if you are too much, you will get stuck in the hole above! If you go back and forth repeatedly, then you can't bear it, although I look like a normal person, I don't have much blood to toss you, so it's okay to keep it this way, but you have to climb up a little bit by yourself! ”

Shen Yuan looked up at the chain that was more than two hundred meters long, and couldn't help but feel dizzy, the 、、、、、、 is so high, even if you don't scare to death, you have to be tired and half dead, right?" Besides, who knows if this thing will be strong! In case 、、、、、、 is a hard and cold stone floor underneath! Can you survive if you fall?

An Jia's second young man didn't speak, and looked up and down the set of black chains for a long time, and the black-clothed people around him still took the first step to check the safety of the chains. Then nodded、、、 An Jia's second young man tinkered for a while, and then turned around and said, "Don't, you still keep that little blood to raise insects!" It's enough for us to use this chain once, so let's hang it here! It's also a back road、、、、、、 send two clever ones up with slingers! ”

The man in black nodded, immediately went over and ordered two sturdy and slender subordinates in camouflage uniforms, and the two of them checked and sorted out their clothes, unloaded their tactical backpacks and went into battle lightly. They also put on two pairs of strange black gloves、、、 and the two of them briefly discussed next to the chain, connected themselves with a safety rope, and each of them had a safety buckle on their wrists, and there were also two buckles in the middle of the rope.

The skills of the two people look superb! The arm strength is particularly amazing, and it only takes a few strokes to climb to a height of more than 20 meters. The two made a few gestures to communicate, and then alternately fixed the buckle and rested for a while, and then began to use the buckle to rest in turn, alternately climbing slowly to save physical strength. It's like a partner who has worked with countless times, one person rests and one climbs and then fixes the two buckles、、、、、、

Gradually, the figures of the two people blurred, and they climbed vertically for two hundred meters! Although there is an iron chain to assist in the force, Shen Yuan still feels that the root of the tooth is sour when he thinks about it! These guys are horrible、、、、、、
