Chen Jing observed the underground world with great interest, there are many kinds of plants in the cave, and the forms are different, but no matter which one of them, they all emit a faint blue fluorescence, which is mainly ferns, vines, and mosses.

There are the largest number of insects here, and there are also a variety of lizards, such as lizards that can change colors and emit blue fluorescent light and hide in underground plants, lizards with slender bodies that are good at climbing, and lizards that move on cave walls and cave roofs, and lizards that are spiky and move slowly to eat moss......

The golden-scaled lizard is naturally one of them, according to the jade slip left by Patriarch Han Zhen, although the projective snake looks very similar to a snake, it is actually a lizard with vestigial limbs.

Chen Jing was passing through a dark cave with sparse plants and blue light, when a powerful aura suddenly approached behind him, and a golden light shot out, and in the golden light was a lizard covered with golden scales.

It was a golden-scaled lizard, Chen Jing had seen one before, that golden-scaled lizard was a fourth-order demon beast, one and a half feet long, with three sharp horns on its head.

The body of the golden-scaled lizard in front of him was also a foot and a half long, but a golden sharp horn grew in front of the sharp horn in the middle of the head, and a row of spikes stood upright on its back, this was a fifth-order golden-scaled lizard, which was equivalent to Chen Jing's realm.

The golden lizard flew near Chen Jing and slowed down, it looked at Chen Jing curiously, but Chen Jing ignored it and continued to fly forward unhurriedly.

This is the experience of the ancestors, Chen Jing carries the ancient lizard dragon bone jade plate, and has the breath of the ancient lizard dragon on his body, so he will not be attacked by the creatures of the underground world.

But high-level demon beasts are very smart, and if you have too much contact with them, you may be recognized, so it's better to stay away.

The golden lizard was the overlord of the underworld, and it observed Chen Jing in a big way, and after a long while, it left, turning into a golden light and rushing forward.

Looking at the direction in which the golden lizard left, and the same road as Chen Jing, the destination of the golden lizard is likely to be the same as Chen Jing, which is not surprising, the place where Chen Jing is going happens to be a place where the golden lizard hunts.

Chen Jing continued to fly forward, and after passing through the huge cave, fog began to appear, and the fog became thicker and thicker, and the temperature began to gradually decrease.

Ferns and vines slowly became scarce, and the moss grew very dense and lush, Chen Jing's divine mind suddenly sensed a third-order demon beast, and he looked at it with his Qi Technique, and there was a snake-like shadow swimming in the moss behind the dense fog.

Chen Jing carefully observed with his divine thoughts, this "snake" was like a black shadow, its body was less than two feet long, short and thick compared to the real snake, and there was a pair of small claws under the abdomen in front of the body, this was the projective snake, this kind of foggy cave was their favorite haunt.

The fog in the cave became thicker and thicker, and he couldn't even see his fingers, and there was only a hazy blue light in front of him, but this couldn't stop Chen Jing's divine thoughts.

After flying for a while, the fog in the cavern faded, but the temperature continued to drop, and the moss was no longer lush.

As we moved on, the temperature was getting colder, the fog was almost gone, the cave was clearer, but the moss was less, and the light in the cave was fainter.

There seemed to be a sound of water coming from the front, not the thin sound of water like the creek and mountain spring, but the sound of overlapping waves, and Chen Jing knew that he was about to arrive at the place.

There is less and less moss in the cave, and the blue fluorescent light gradually disappears, but the cave is brighter, and the four walls of the cave here are all blue and turquoise jade, and the blue light emitted by the jade illuminates the cave.

The cave is getting bigger and bigger, and it begins to gradually tilt downward, and the sound of the water is getting clearer and clearer, and it flies out two or three miles away, and suddenly the front is bright, and a huge cave without friends appears, which is hundreds of zhang wide, much bigger than the huge cave where the Xuanfeng Palace is located, and below the cave is a huge pit abyss.

The four walls of the cave are blue and blue jade, the blue light emitted illuminates the whole cave, the huge pit under dozens of zhang is a black and heavy water surface, as if there is a bottomless abyss, there is no wind underground, but there are waves on the water surface, gently lapping the jade walls on the four sides.

According to the jade slips left by the ancestors, this is Yuyuan Lake, and the pool under the giant pit is connected to a huge underground dark river, so there will be no wind and waves.

There are many strange and terrifying underwater creatures in Yuyuan Lake, according to Patriarch Han Zhen, Yuyuan Lake should be a place where ancient lizards and dragons hunt, and golden-scaled lizards and projective snakes also like to hunt and eat aquatic creatures here.

The cold air in the cave is biting, and a lot of turquoise stalactites hang down on the top of the cave, and a little drop of water seeps out from the top of the cave and drips into the deep pool below.

The temperature of these seeping water droplets is extremely low, and the top of the cave is shrouded in a thin layer of cold smoke, these water droplets seem to be more important to the creatures in the underground river below, and will lead them from the underground river to the Yuyuan Pool.

Chen Jing came here to collect some water droplets oozing from the roof of the cave to see if the blue water hyacinth was used well.

However, he didn't rush to make a move, there were a lot of golden-scaled lizards and projective snakes around Yuyuantan, and the creatures in the water were also powerful, so he had to observe them first.

There was only the sound of the waves in the cave, and it seemed to be peaceful, but this was the hunting ground of the golden scale lizard and the projective snake, both of which hid their own breath, and Chen Jing also carried the wood and stone trail and the divine veil early to hide his own breath.

He looked around with the Qi Hope Technique, and there were nearly seven or eight golden scale lizards and projective snakes on the jade wall around the giant pit, among which two golden scale lizards and one projective snake were high-level demon beasts, and two golden scale lizards were fifth-order, one of which was met by Chen Jing on the road, looking at the "qi" on the projective snake's body, it should be a sixth-order demon beast.

Chen Jing was secretly frightened, these three high-level demon beasts should have noticed Chen Jing, but he was carrying the ancient lizard dragon bone jade card, and these three demon beasts ignored Chen Jing.

Chen Jing was dressed in a green shirt, floating on the edge of the blue and blue stone wall, and he was not very conspicuous, he was an irrelevant passer-by to the creatures in the cave and under the water.

The waves on the water surface under the giant cave are bursting, and if you look carefully, there are many shadows under the dark and heavy water surface, and you can watch them with qi magic, many of which have ice-blue "qi" on their bodies, some like fish, some like insects, and the creatures in this underground dark river are very strange.

Whenever there are water droplets falling on the top of the cave, these fish and insects will gather over, and there are many water droplets, and the range of drips is very wide, and the fish and insects under the water surface gather into many groups and swim back and forth with the water droplets.

A few drops of water fell near the edge of the jade bi, and a small group of fish and insects in the water immediately swam over, and Chen Jing knew that there was a golden-scaled lizard and a projective snake on the jade wall near them, so he narrowed his eyes slightly.

Suddenly, a faint snake shadow bounced towards the water, and a snake-shaped black light shot out of her mouth!
