As soon as I got down here and stood still, all of a sudden, there was a cool wind blowing from here. The wind was so cold that it was biting to the bone. Like a knife cut on his body, Yue Yi shrinks. He first looks back and sees a pool at the end. The gurgling stream flowing out of there flows into the pool, and then into the underground river.

As for the passage in front, it's very deep, narrow, dark and cold.

Leyi comes to the stream and looks at the fish swimming in it. They are all black. Perhaps this kind of fish living in the underground are very similar, so they look like catfish on the earth.

The other difference between the two points lies in their fiery red beard and a horn on their head.

When Leyi stood at the edge of the stream and observed the fish, suddenly there was another fish in the stream, jumping up and biting him.

The mouth is open, at least the size of a palm, and the tusks in the fish's mouth are one or two centimeters long. If it bites, at least a piece of meat can be torn off.

Leyi immediately turned into gold with his right hand. With one hand, he cut the fish in half.

After the fish fell to the ground, the two halves were still jumping. Then they both jumped back into the water and could swim. The two halves swam to one side.

"It's really strange."

After retreating a few steps, Leyi goes inside. The more he goes inside, the wetter the ground will be.

About 300 meters into the cave, the top of the cave began to drip water, which is from the stalactite dripping water.

It's extremely dark inside. Leyi's night vision eye has played an unimaginable role. No matter what, it's really seen by him.

There was no living creature in it. It seemed that after leaving the stream, he never saw anything moving in it.

Some black plants are the exception!

Those plants, like mushrooms, grow in groups, emitting a strange taste.

With the experience of the ancient world under the lake, Leyi keeps the wolf Amber Alert for himself at any time. In this way, no matter whether the inhalation is toxic or not, it will not cause damage in case.

Sizzling

Until Leyi entered more than 500 meters, a strange sound began to appear in it. It's like a poisonous snake spitting a message, but Leyi can't see it all around.

Sizzling

The sound is still there, as if it's in my ear, but Leyi can't find its place when he looks around.

Even if we release the inductive force, we can't sense where the object is.

Leyi takes a calm attitude and continues to walk inside. When it reaches more than 800 meters. The front suddenly becomes spacious, there is a ring of spacious ground, and this cave seems to end here.

It's only so deep. This is the end of it!

"It's really not an ancient world. It's only 800 meters deep. It seems that it's just an ordinary underground cave." Yue Yi is a little disappointed. Since he has nothing, he can only go back home.

Sizzling

But at this time, he just turned around and suddenly saw a huge voice standing behind him.

The thing opened the blood basin, big mouth toward his head, just a bite came over.

"Evil animal!" Leyi's reaction was very fast, and it fell back immediately.

And that thing's reaction was not slower than him. In the big mouth of the blood basin, he suddenly spat out a tongue with a barb and flew out Hula. As soon as he threw himself on Le Yi, he rolled him up.

When it rolls up Leyi, its tongue will pull Leyi into its mouth!

But le Yi was furious and fought against the monster with the power of ten oxen and two tigers. However, as soon as the power was exerted, he was surprised to find that his legs were sliding on the ground, and his strength could not compete with the monster.

"Here comes the knife!"

The light of Leyi's storage ring flashed, and the empty tooth knife suddenly flew out. Under the control of Leyi's mind, he cut the tongue with a knife.

When the huge monster saw the blade fall, its tongue suddenly released itself, and then retracted into its mouth.

After Yue Yi gets out of the body, he grabs the empty tooth knife, and the cold force rushes into the empty tooth knife. The whole empty tooth knife is suddenly extended by 10 meters, and it's cold.

If the monster does it to him, he will naturally do it to the monster.

By this time, he had seen clearly. This huge thing, dark red all over, looked like a prehistoric lizard.

"Hoo Hoo Yue Yi's long sword dances and cuts to the monster's head with a knife.

The monster's 10 meter long body and huge head are no less than that of an elephant. With Leyi's means, it can be killed every minute.

However, after the first cut, Leyi realized that he was wrong. And it's a big mistake. Although the lizard's body is very huge, its moving speed is very strange and fast.

I saw it all of a sudden around the body, the steps do not know what the track, even a breath, it floated away. Back ten meters away, two huge eyes stare at Leyi with hostility.

Leyi also rushed to the past at once. As soon as the speed of the wind passage was used, the wind stepped on the wind. The speed was as fast as lightning, and a knife struck the lizard again.

However, the lizard suddenly performed that strange footwork again, and it was able to avoid this knife. Then the gecko swam the wall. It really had the ability of gecko and climbed directly towards the steep rock wall.

When climbing more than ten meters, it suddenly jumped down, and its long tail whipped towards Leyi like a whip.

With a sneer, Yue Yi holds on to the empty tooth knife and waits for its active attack.

When its tail is waving, Leyi's empty tooth Dao attribute changes suddenly and turns into a golden long Dao, which is indestructible!

"Break it for me!"

A knife fell, this time, the giant, completely Dodge, long, with barbed tail, with empty teeth knife together. The empty tooth knife turned into gold was extremely sharp. Under the knife, the tail of the giant broke on the spot, fell to the ground and swayed left and right.

The monster's tail was cut off, and no blood ever flowed out. At this time, it was faster, but instead of continuing to attack Leyi, it ran to the depth, ran to the end, pushed away a stone, and then went into a hole the size of a dog hole.

"That's it? What on earth is this, so fast? "

Leyi also follows the "dog hole" and looks inside. It seems that the hole is also very deep. But he didn't plan to go to this "dog hole" to have a look.

Looking around, there was nothing special, so he was ready to go back.

But just as he turned around for the second time, there was a faint voice in the dog hole: "young man, all of you have come, don't you come in and see me?"

If you don't listen carefully, you can't hear it at all.

And even if you hear it, it's also like hearing a child's somniloquy. The voice is very shallow and hazy.

"Who's talking?" Leyi gave a drink.

The words were called out, but no one answered.

"Illusions?" Le Yi frowned.

At this time, the sound of "if you have nothing" came again: "it's not an illusion, young man. If you go inside, I'll be there. If you come here, why don't you see me?"

This time, Leyi is sure that he has never heard wrong and that it is not an illusion.

The sound is really inside, and it seems to come from the "dog hole".

"You're in the dog hole?" Yue Yi asked.

"Ha ha, it's not a dog hole, young man. You'll know when you come in." If there is no voice in reply, the voice is very dull, like across a lot of paper in the mouth, to make this sound.

Yue Yi hesitates for a moment, grabs the empty tooth knife in his hand, then moves his muscles and bones, and folds up his muscles and bones just like the original three links.

All of a sudden, Leyi is more than half short.

This operation is bone reduction! Ordinary people have to work hard all the year round or have individual talents.

But this time, after the mysterious pill washing tendons and cutting marrow, Leyi's muscles and bones are not as good as before. Now it's easy to perform this osteotomy.

At the end of the osteotomy, Leyi is like a three-year-old child. At this height, he can walk in.

After all, this hole is a dog's hole, but it's not a dog's hole. The lizard just now is at least as big as an elephant, and the hole it can pass through is naturally not small.

It's just that Leyi is afraid that the space inside will become smaller. If he is too big, his goal will become bigger. As soon as this bone shrinking technique is performed, his goal will become smaller.

Immediately, holding a knife, he rushed into the hole.

But after only 30 meters, he saw a cliff in front of him, and under the cliff, there was only a dry well.

The well is about 50 meters deep and about 10 meters in diameter.

There are a lot of rocks, dead grass and some huge chains under the well.

Leyi clearly saw that the huge lizard was lying on the withered grass and licking its tail.

When Leyi saw the lizard, the lizard also saw him. Because he had suffered losses in Leyi's hands, he immediately got up and drilled under the rock, and disappeared immediately.

Leyi called out: "where are you?"

"Down here, down here. If you remove these stones and withered grass, you will see me." The voice is clearer here.

Leyi can indeed hear it. The sound really comes from under the withered grass and rocks!

It made him curious. Who would be in such a place? And listen to voice so old, age is not small.

Can it be Xuanyuan Lingyuan, a historical old man?

With a curious mood, Leyi jumps down, but keeps alert at any time. First, he burned the dead grass with a fire, and then moved the stones out one by one

When you move to the end, who's down here?

But I only saw a big chain wrapped around a half meter high jar with a seal written in Rune on it.

"Where are you?" Yue Yi looks at the jar and asks tentatively.

"Hey, hey, hey... I'm right in front of you." A strange voice suddenly came from the jar.
