Guo Xuan's moth found a tree hole in a huge ancient tree by the lake.

The shade of the trees obscured the moonlight, and in the faint light of the fire fold, the three of them looked at each other for a while, and Guo Yu blew a low whistle and withdrew the glowing moths.

Guo Hua pondered, just in case, he took out a pair of special gloves, the gloves were made of a whole piece of sea shark skin, tough and corrosion-resistant, ordinary sword venom, it could not hurt it.

Guo Hua put on gloves and reached into the tree hole to grope for a while.

With a thud, a metal chain was torn off. Immediately afterward, there was a loud rumbling sound of a winch spinning underground.

The lake in front of him stirred, Xian Yuyan's face turned cold, and he pulled out his double knives. Recently, Xian Yuyan has been carrying two knives on his back, and as far as what needs to be done at the moment, the dagger that dissolves the flesh is really a bit useless.

Guo Yu also discovered this and knew that Xian Yuyan was concerned about the recent events, but what he wondered was that Xian Yuyan seemed to be proficient in many kinds of blades, and the double knife might not be what he was best at.

There was a sound of water coming out of the water, and in the moonlight, a rope bridge clinging to the surface of the lake appeared in front of the three of them.

The rope bridge is very simple, just with two copper chains, connected to a piece of wood, without guardrails, and even, it seems, this rope bridge should have no buoyancy, if you can't do it, you will inevitably fall to the bottom of the lake if you step on it.

The deserted courtyard, the hidden and ingenious mechanism, I am afraid that the bottom of this lake will never be as calm as it seems.

The rope bridge juts out into the middle of the lake, where a platform rises more than two feet above the lake.

The smoke snake, as if spiritual, shook a few times, and then swam along the rope bridge to the platform.

The three of them performed light skills, tapped the wooden plank, followed the smoke snake, and came to the platform where the strange appearance appeared.

Guo Hua looked at it, the whole platform should be made of willow wood, and a piece of leather was wrapped around it for waterproofing, and when he touched it, he couldn't see the material, but it should be some kind of huge animal.

Because on the high platform they are standing on, there is a square circumference of more than ten people, and the wrapping of this platform should be a whole piece of skin, plus the depth in the water, I really can't imagine what kind of creature this is.

In the center of the table is a trap lock, and more than a dozen wooden strips are interspersed and snapped together to form a square wooden block, which is a variant of the Luban lock.

It is not difficult to meet the people, Lu Ban locks all kinds of deformations and different shapes, Guo Hua has played a lot of them, and he lifted the mechanism in a few clicks.

A door opened, revealing a dark cavern in the middle, and the moonlight was not too deep to see below.

"You can't throw the torch down, I'm afraid it's full of wooden beams and columns, what should I do? Xian Yuyan muttered.

Guo Hua looked at Hui Lin, and the smoke snake lingered at Hui Lin's feet, as if it was moving.

"Senior brother, this Hessian cave still has to invite your sun shadow!"

"Within more than thirty zhang of this passage, there is no ambush, it is all because you are not skilled in kung fu, otherwise you can walk in it. As for this Xianyu brother, I'm afraid, you don't need torches for your eyes!" said Hui Lin.

When Xian Yuyan heard this, a trace of shock appeared on his fat round face, which appeared in an instant, and disappeared in an instant, he didn't hear it, didn't answer, didn't speak.

Guo Yu didn't think much about it, he knew that Xian Yuyan's eyesight was outstanding, especially when he walked at night, which was more real than ordinary people, but in this dark cave, there was no light, how could he dare to go? There was no ambush, and he was afraid that there would be a mechanism.

Guo Yu didn't think deeply about Hui Lin's words, and Hui Lin didn't say anything more, and took out a bag from his arms.

Sun Shadow is the name of a jewel, it is the treasure of Shule Kingdom, Hui Lin came to Chang'an, and Sun Ying followed Hui Lin to Chang'an.

The white and soft light of the sun shadow and the bright moonlight are also very special. Hui Lin urged the spell, and the Sun Shadow slowly drifted into the dark hole.

The three followed, along with the smoking snake.

There is an extremely steep wooden ladder, surrounded by keel-like wooden structures supporting the four walls, annular wooden pieces, and copper locks and bracket links in the middle, the structure is exquisite and meticulous. It seems that this paragraph is scalable.

The wooden ladder is steep, but fortunately there is the light of the sun's shadow, which illuminates the passage as bright as day, but it is not dazzling, and the details of the corners can be seen clearly.

Walked about more than ten zhang deep, came to a stone cave, the entrance of the stone cave is two zhang away, the edge has a bronze cast door frame, look at the beast face on it, cloud pattern, it should be something in the Shang and Zhou dynasties.

It is strange that there is such a place under Chang'an City. Walking further in, it can be seen that this stone cave is half natural, half has traces of artificial excavation, and there are some bronze or stone beasts along the way, bears, horses, rhinoceros, phoenixes, dragons, etc., some are half human-high, and some are taller than everyone else. Very graceful and majestic. Shapes and techniques are not objects of this dynasty.

It was a very long road, and because of these strange statues, all three of them walked very slowly. When Hui Lin saw it, she was also surprised by the wisdom of the ancients, and Guo Hua was naturally even more surprised as she walked.

Only Xian Yuyan looked at these statues, and his eyes seemed to think of something, a complex expression that seemed sad, but also a little excited and joyful, intersected in his eyes.

Because she was obsessed with the magnificence of the sculpture, even the careful Hui Lin didn't see Xian Yuyan's complicated expression.

Deep in the crypt, the trio gradually lost their sense of time. It must have been after walking for a long time, and the sound of the wind in the cave gradually rumbled violently.

"It's strange, although the wind is loud, it doesn't feel strong when it blows on the body. Guo Hua asked.

"It's the sound of water! The dark river underground, there should be a thousand steps away. Hui Lin seemed to be more serious than the two, and replied to Guo Yu with a solemn expression.

"No wonder the cave doesn't feel depressed at all, it seems that the flow of the dark river has driven the flow of breath in the cave. ”

There were no people along the way, no forks in the road, no hidden passages, and the smoke snake kept swimming towards the front.

"Could it be that I'm mistaken? Nothing happened along the way. Xian Yuyan muttered.

"Probably not!Let's go first!" Hui Lin looked at the smoke snake, slowly replied, and then quickened her pace.

The two of them followed, the rumbling sound of the water became louder and louder, and the cave gradually expanded outward, the same as the horn.

After walking for a while, the light of the sun seemed to burst out suddenly, and a vast space was revealed.

suddenly opened up, and it also made the three of them feel uplifted. In front of him was an extremely vast space, and in front of him was a wide underground river, with rolling waves, and the sun and shadow shone fifty feet away, and the river and the roof of the cave were not in the darkness.

On the top of the cave, a huge number of pearls and sun shadows reflect each other, forming a beautiful picture of the stars and the Milky Way, seeing this magnificent Milky Way, the three of them can't help but exclaim in unison.

I can't see the other side, so wide underground river.

The three of them looked at it for a while and found that on the right hand side of the cave entrance, there was a hand-dug trail, which could accommodate five or six people to go together. I don't know what era a project of this scale was done, and it should have cost a lot of human and financial resources.

After walking a long way, Xian Yuyan yawned, and the three of them felt a little sleepy, and it was probably late outside.

The flow of the water became more and more gentle, and in one place the river divided into three tributaries, the middle one was wider, and you could see the hands of bronze figures on the walls of the caves along the way, full of torches.

"How did you get there? The situation in this river is unknown!" Guo Hua asked as he turned to Hui Lin.

"You don't need to go over, you see that this smoke snake is not pointing there, and this road is not broken, it should lead all the way to the depths of the dark river on our side!"

Indeed, the smoke snake continued to swim and had no intention of changing direction.

Guo Yu and Xian Yuyan looked at the wide river illuminated by the lights, and hesitated for a while, it stands to reason that there is a better chance to find someone there.

You still have to believe in your brother's technique, and it is important to save people. Guo Yu motioned for Xian Yuyan to follow Hui Lin, and the three of them stepped into the narrow dark river on the right.

Hui Lin walked briskly and was in a good mood, and in the light of the sun's shadow, she looked around at the ancient paintings on the rock wall of the river.

The handwriting of the petroglyphs is ancient and simple, there are huge beasts, and there are ancestors who hunted in animal skins and leaves, and they should have been painted with blood, gum mixed with mineral sand, and toner.

The subject matter of the painting is also relatively simple, most of them are giant beasts, big fish, birds of prey, and some monster-like birds and beasts, which should be imagined by the ancestors.

This narrow river channel is older than the tunnel when entering, and those simple murals are also more bloody and primitive, with simple brushstrokes and color blocks, depicting the grand and bloody hunting scenes of ancient times.

Hui Lin walked happily, and he seemed to like the petroglyphs. Guo Hua was shocked by the bronze relics of Shang and Zhou before, and now he is even more dumbfounded. He had heard about the legends of his ancestors, but it was the first time he had seen such a magnificent scene, and his thoughts seemed to be pulled back to the ancient hunting grounds thousands of years ago.

A corner appeared in the river, and a gap appeared in the brilliance of the sun shadow temporarily, and when Guo Yu turned to look sideways, he was suddenly startled, Xian Yuyan was gone.

Guo Yu sighed softly, Hui Lin understood, knew that there was a situation, and flashed back in an instant.

Xian Yuyan is gone. Hui Lin saw the situation at a glance.

The two hurried back. Unconsciously, this narrow section of the road can only accommodate one person to walk, Hui Lin waved her hand, performed footwork, and went around to the front.

Guo Wei understands that in this narrow trail, it is difficult to perform his kung fu, but Hui Lin, who is good at water scrolls, has undoubtedly become the strongest person here.

The river is narrow, and the brilliance of the sun's shadow is also limited. The two walked back more than 200 steps before they saw Xian Yuyan.

I saw him standing there with his mouth wide open, his wide eyes protruding out, although he didn't look carefully, he could imagine that it was a pair of bloodshot eyes, and a strong killing intent soaked Xian Yuyan's body.

Guo Hua was about to shout, when he saw Hui Lin make a "quiet" gesture.

"He's infected by these petroglyphs!" said Hui Lin softly.

"What's so strange about these petroglyphs, how do you and I ••••••?" asked Guo Xuan.

"Hehe, how much do you know about your friend?" Hui Lin didn't answer, but asked Guo Yu.

Guo Yu was stunned, Xian Yuyan is a descendant of the Eile clan, also known as the Gaoche clan, according to what he confided last time, Xian Yu's ancestor is still a high priest and a great shaman, who can be incarnated into a wolf, is this understanding considered much?

Could it be that Xian Yuyan has a more mysterious past than these?

Guo Yu just wanted to ask something more, but saw Hui Lin suddenly make a warning gesture. There is danger ahead.

At this time, the two were only more than twenty steps away from Xian Yuyan, and Hui Lin stopped. Guo Yu suddenly discovered that in the water under Xian Yuyan's feet, something poked out a huge head.

The Shadow continued to fly forward for a while, and saw clearly.

There are two huge heads more than three feet above the water, each one is the size of a bull's head, like a crocodile but not a crocodile, like a python not a python, and there is a single horn in the middle of the beast's forehead, which is more than a foot long, and is sharp and matchless.

The two giant beasts opened their mouths, and the countless sharp teeth in their mouths were chilling. The two eyes glow a terrifying red light when they are in the dark, but in the light of the sun's shadow, they are miserable, and they can't distinguish between the pupils and the whites of the eyes, which is probably caused by living in this lightless underground for a long time.

The two giant beasts should have been attracted by Xian Yuyan's strong murderous aura, and at this moment, they were looking at the short and fat strange species in front of them, maybe they were also afraid of the strong killing intent on Xian Yuyan's body, and they didn't dare to act rashly.

"This is an ancient god!" on the petroglyphs, I have seen it, it seems to be the patron saint of a certain tribe!" Hui Lin said lightly.

The two giant dragons also noticed the abnormality, their eyes slanted slightly, after a long time, it seems that they are not blind, perhaps, they can already see in the dark environment.

I saw that their originally hideous faces instantly showed a trace of killing intent, and suddenly, the momentum started, and they had the momentum of devouring the swallow alive.

Guo Yu exclaimed in surprise, and saw the two Shenjiao suddenly raise their bodies and retract back, as if they had received a huge suction.

It was water, flowing like glue paint at the moment, tightly wrapping the two ancient beasts, and no matter how much they struggled, they couldn't get out of the water.

Yes, Huilin. It was Hui Lin who urged the powerful secret method to manipulate the river and trap the two giant beasts.

Xian Yuyan also came back to his senses, realized the danger, instinctively rushed towards the two, and turned to look at the two giant Jiao.

Xian Yuyan drew his double knives and leaned against the rock wall. Hui Lin kept chanting spells, manipulating the river and fighting with the two giant dragons.

I only saw the head and neck of the giant jiao, and I didn't know what it looked like under its body, or how huge it was. However, after all, they are born in water, and they are familiar with water, and although Hui Lin's magic is strong, it is difficult to subdue them in a moment.

The two giant dragons shook their bodies frantically, their tails flapping up and down, and subtle beads of sweat gradually appeared on Hui Lin's forehead. The strength of the two giant beasts is really extraordinary.

The rock wall of this dark river looks very hard, and his earth scroll has just been cultivated, so I don't know if I can manipulate it. Guo Yu thought, formed the seal, and recited the mantra.

The rocks on both sides and at the top began to crumble slightly, and the sand and stones of Suosuo continued to fall, and more than a dozen rocky arms stretched out, or clenched fists, or formed palms, constantly attacking the evil Jiao.
