Xiao Nan harnessed the Heaven Devouring God Gourd and slowly approached the island.

When there were still 5,000 feet, the scene on the island finally appeared clearly in front of the two of them.

I saw that this island was suspended in the lake water, exuding a faint fiery red light, stretching for thousands of miles, and the island was covered with dense aquatic plants, these aquatic plants were extremely soft, and with the flow of the lake, they poured down in rows in the direction of the current.

"The light emanating from the island is very penetrating, and it seems that the reason why there is light in this lake is the reason for this island. ”

Xiao Nan looked at the huge island in front of him, and didn't notice that it had the slightest movement, the faint red light on it scattered out, and the soft light gradually penetrated into the lake, these lights actually flowed into the distance with the current, continuing the function of illuminating the lake, and did not disappear because of leaving the scope of the island, and these lights were gradually transforming into the color of the lake, and it seemed to be integrated with the lake.

This phenomenon broke Xiao Nan's cognition.

"What the hell is going on? we didn't find any signs of life on this island so close, it can't be that we misjudged, right?" Xiao Nan said suspiciously.

"When I look closer, I always feel that the danger is getting closer. The Netherworld Snake Emperor's face was solemn, and Xiao Nan could even clearly see the sweat oozing from his back.

Finally, the Sky Devouring Divine Gourd approached the surface of the island, and the feeling of danger disappeared, Xiao Nan and the Nether Snake Emperor walked out of the Sky Devouring Divine Gourd and landed towards the surface of the island.

"Master, the lake near this island is so strange. ”

The lake here does not seem to have the slightest buoyancy at all, and such a phenomenon should not have happened in the tens of thousands of feet of underground lake.

"Stay safe, this is tens of thousands of feet underground. The temperature of the surrounding lake should be very high, but there is no such scorching breath here, and there must be demons when things go wrong. Immediately retreat at full speed. ”

Xiao Nan looked at the lake around him and felt that something was wrong. But I can't tell what's wrong.

There is no living thing here, only a palpitating death, and even the aquatic plants on the island exude a death smell, as if it had long dried up on the surface of the island.

The water is clean and transparent, and there is no impurity!

Moreover, Xiao Nan is in this lake. I didn't feel the slightest bit of stuffiness. A qiē is like the feeling of being outside in broad daylight!

Xiao Nan absorbed the Creation Divine Qi, and the Creation Divine Qi emitted a shining brilliance, wrapped around Xiao Nan and the Netherworld Snake Emperor, and dived down together, Xiao Nan and the Netherworld Snake Emperor did not deliberately urge the power, and their bodies slowly sank in a free fall.

A qiē is so calm.

I don't know how long it has been sinking, Xiao Nan finally felt that he had stepped on the ground of the island.

The surface of the island is a layer of dark red stone. When you step on it, you have a soft feeling, which is as far as the eye can see. The entire surface of the island is full of such stones!

On the surface of the red stone, there are small dark red holes, and countless hot bubbles emerge from the dark red holes.

The entire lake becomes warm and pleasant.

Xiao Nan stood on this red stone slab with his feet. I felt the warmth of my feet, and there was no burning sensation at all. Looking at it, I can't help but be amazed in my heart.

In the center of each small hole, there is a tall and thick aquatic grass, densely packed. Let Xiao Nan feel like he is in a dense forest.

"What kind of existence is this, I didn't expect that there is such a place in this underground lake, who is it that at the bottom of this lake, there is such a miraculous arrangement! ”

"Yes, this red stone, which I have never seen before, seems to be very tough, this soft feeling, more like standing on the surface of some kind of creature, but there is no sign of life here, it is really strange. There is also this kind of aquatic weed, which can't be pulled out. ”

The Netherworld Snake Emperor grabbed a water plant in front of him with both hands and pulled it upwards with all his might. With his Da Luo Jin Immortal peak realm, he couldn't pull out a single water grass, which made him feel a strong sense of frustration.

Xiao Nan slashed at the aquatic weed with his divine sword, but the aquatic weed fell down in the direction of the chopping, as if it was powerless. The Excalibur, which sharpened iron like mud and made a decisive decision, did not cut off this aquatic weed, but only left a shallow trace on it. A red light suddenly flashed on the aquatic grass, and the trace disappeared in an instant!

Xiao Nan couldn't help but gasp, looking at the cold and shining divine sword in his hand, and even wondered if this was his invincible divine weapon!

"It's really an evil sect, a single aquatic plant has such a hardness!" the Netherworld Snake Emperor also smacked his tongue, his eyes flashing with disbelief.

Xiao Nan was about to vigorously chop this aquatic weed again, when directly in front of him, there was a sudden fluctuation that seemed to be absent, and the aquatic grass in front of him suddenly separated to both sides, revealing a narrow passage.

The Thunder Sword in Xiao Nan's hand suddenly became excited, and with a flash of light, he took the lead in taking Xiao Nan towards the place where the fluctuations were emitted.

Xiao Nan's heart moved, and he followed, and said in his heart, could it be that the Netherworld Snake Emperor and himself had all misestimated? What is the danger here? There should be something needed for the divine sword here.

Although he thought so in his heart, Xiao Nan did not relax his vigilance at all.

Hundreds of feet suddenly came out, and a hole with white light flickered in front of him! It was on the surface of the island, leading straight to the ground.

The entrance of the cave, emitting a soft red light, makes a cordial call. It seems to be saying to Xiao Nan, come on, come on! There are good things waiting for you here!

Xiao Nan clearly felt that there was something in it that he had been demanding all his life. Xiao Nan didn't hesitate and threw himself in!

The Nether Serpent Emperor followed behind and shouted, "Master, be careful, it's too abnormal here!"

And Xiao Nan didn't seem to hear the reminder of the Netherworld Snake Emperor, he had already thrown himself into the cave!

The caves inside this island are unusually wide, hundreds of miles in size. There are many strange rocks inside, and the passages are criss-crossed, and each passage leads to an unknown place.

There was not a drop of lake water in the cave, as if a small world had been carved out of the lake.

The only thing Xiao Nan didn't understand was that outside the cave entrance was obviously an endless lake, and there was no isolation device, but the water seemed to be blocked by an invisible and intangible barrier, and not a drop could penetrate into the cave space.

The cave glows with a faint red glow everywhere, giving the contents a bewitching, mysterious hue.

At this time, the Netherworld Snake Emperor also jumped down quickly, standing beside Xiao Nan, his eyes were round, and his mouth was open enough to stuff a live toad!

"What is this place?"

Xiao Nan would never have imagined that what they came to would be such a place!

If he had known in advance, even if he knew that this was not true, he would rather give up the treasure than come here!

Just when the Netherworld Snake Emperor asked this sentence, Xiao Nan only felt a blur in front of him, and the red light in front of him suddenly disappeared, and the entire cave space turned into darkness.

Xiao Nan was shocked in his heart, and he didn't understand what was going on, but the Thunder Sword in his hand was excitedly pointing to a place, struggling to let Xiao Nan pass, Xiao Nan walked a few steps tentatively, and his vision changed, only to see that there seemed to be a faint light in front of him.

Xiao Nan couldn't help but feel strange, he took a few steps back, and the light in front of him disappeared again, turning from new to dark.

"There seems to be a spatial barrier here, which can isolate the penetration of light, but it does not affect the penetration of the human body, it is really a clever arrangement, just this technique, it proves that the owner of this formation has the ability to build heaven and earth. ”

Xiao Nan felt the changes in the cave and sighed sincerely.

"Yes, if the master here is going to work against us, it seems that we will have to die here. "It's the first time that the Nether Snake Emperor has given birth to such a thought, although he has reached the state of immortality, he still faintly feels that there is a powerful force here, which is enough to make him lose his soul and not enter reincarnation.

Xiao Nan walked forward step by step under the guidance of the Thunder Sword.

The direction that Excalibur was pointing in was where the light was.

The Netherworld Snake Emperor was behind Xiao Nan, and he followed step by step, and the two walked a distance of nearly a hundred zhang, and a hole appeared in front of them, and the light came out of this hole.

The body of the Thunder God Sword suddenly shone brightly, and it actually broke free from Xiao Nan's control and shot towards the hole.

Seeing the scene in the cave, the Netherworld Snake Emperor showed an excited look on his face, and he quickly crossed Xiao Nan's body and rushed towards the cave.

As he ran, he shouted loudly: "Master, there is a soul refining stone here, such a good thing, don't let the Thunder Sword devour it, that would be a waste!"

Xiao Nan took a closer look, and saw that in the center of the cave, there was a stone case, on which was a fist-sized stone, and the stone emitted a faint blue light, which was incompatible with the surrounding environment.

Xiao Nan didn't find anything special from this stone, and seeing the Netherworld Snake Emperor's excited appearance, Xiao Nan was confused. How many years have you said you have lived, and when you see a blue stone, you have such a look.

Even if this stone is a treasure against the sky, if the Thunder Sword devours it, will it increase my combat power?

Seeing that Xiao Nan was actually standing in place, without the slightest reaction, the Netherworld Snake Emperor couldn't help but be anxious: "What are you still doing in a daze, and you still don't control the Thunder Sword! If he devours it, not only will he waste this fast treasure, but it may also bring us a catastrophe!"

"Oh, what you said is a bit arbitrary, how can the Thunder Sword devouring this stone bring us disaster?" (To be continued......)
