The little golden beetle seemed to understand Song Anran's words, shook its wings, and flew up!

It first circled over Song Anran's head, suddenly accelerated, and flew quickly in one direction!

After all these years of adaptation, Song Anran has adapted to the darkness here!

He found that it was an even larger cave space, hundreds of meters high, and high on the left cave wall, there was a waterfall that spilled from the mouth of the cave and merged into the river below.

The river meanders and disappears at the cave wall, turning into an underground river.

Song Anran kept jumping on the ground, crossing rivers or rocky obstacles, chasing the little golden beetle flying fast in the air!

He didn't want to lose the little golden beetle, because there was a very thin silk thread that connected each other!

The little golden beetle flew into a cave passage that was fifty or sixty meters high!

There are marks of friction at the entrance of this cave, and it is obvious that there are giant beasts entering and leaving.

Song Anran didn't hesitate much, and chased after him!

The little golden beetle flew this time, and more than two hours have passed!

Calculating the distance, Song Anran felt that he had traveled at least a hundred kilometers away. At this moment, he had long lost his sense of direction and depth, and could only follow the little golden beetle all the way deeper.

The fierce beasts and insect swarms encountered several times along the way, the golden beetles passed without any hindrance, but Song Anran was attacked by them with all their might!

Fortunately, he only wanted to pass quickly, relying on his agile body and the sharp bone knife in his hand, these attacks did not hinder him much!

After walking out of a passage again, a pale red underground world suddenly appeared in front of Song Anran's eyes.

The dome is at least 100 meters away from the ground, and the stone pillars with tens of meters and tens of meters of thickness stand up to the sky, supporting this magical underground world.

There are rivers crisscrossing the grounds, as well as lakes!

Plants such as moss on the ground, cave walls, and stone pillars glow with a faint red glow, and the rivers and lakes on the ground also glow with a pale red glow, illuminating this vast space!

Song Anran saw at a glance that there was a huge figure in the middle of the height!

This is a giant insect magnified by a small golden beetle ten million times, its body length is more than thirty meters, but the color is not golden, but a faint silver-gray, and there are two tentacles on the head that are seven or eight meters long, and the curved horns are as long as three or four meters!

The little golden beetle flew over happily and stopped on the tentacles on the giant beetle's head!

Song Anran knew that this was the so-called female worm!

He had heard Meng Shuiyao's description of this female worm according to Meng Weiwei's memory, and he was shocked by its enormity just by seeing it with his own eyes!

It's really strange on the earth that there are such large bugs!

At this moment, Song Anran, who was emotional, felt the ground shake, and found that the giant insect was supported by eight arthropods and stood up, and two crimson, football-sized compound eyes flashed with bloodthirsty light, staring at him!

Meng Weiwei once said that she can communicate with the mother worm, and obviously this big worm has a certain amount of wisdom!

Song Anran stretched out his hand and pointed at the giant insect and shouted, "Come on!"

The giant insect was immediately enraged, and let out a terrible sharp roar like metal friction, and immediately galloped towards Song Anran.

On the way, it can be described as huge, rumbling like a heavy tank, the ground trembled, and the rocks blocking the way were either knocked into the air or trampled to pieces!

Song Anran also roared, and launched an attack against the giant insect!

Halfway through, he stepped hard, jumped up dozens of meters directly, avoided the attack of the giant worm's long horns, and then under the traction of the silk thread, his body suddenly fell and fell on the head of the giant worm.

Song Anran held the long bone knife upside down with both hands, and with all his strength, he inserted it into the head of the giant insect!

The long bone knife pierced in, and Song Anran only felt that it was like stabbing on an alloy metal ingot, and the hardness was extremely amazing!

With the sharpness of the long bone knife, coupled with Song Anran's strength, after piercing half a meter deep, he couldn't move an inch again.

At the time of emergency, Song Anran immediately attached a gray shadow to the long bone knife, so that the bone knife was not finished!

However, the feedback from the gray shadow turned out to be that the carapace had not yet been pierced!

The carapace of the head of this giant insect was so thick, more than a meter.

At this moment, the giant insect suddenly let out an earth-shattering hiss, and its head trembled at an incredible frequency, instantly bouncing Song Anran away.

Song Anran was still in mid-air, and the giant insect just stretched out its head, and the long horn had already picked under him!

The long horns of the giant worm flashed with a faint cold light at the sharp edge, and Song Anran only glanced at it, and he couldn't help but feel a chill in his heart, knowing that it was best not to be picked by the long horns.

Song Anran, who was in the air, turned over and twisted his waist, and the long bone knife slashed heavily on the long horns!

Boom!

A dull sound like rolling thunder suddenly sounded, and the entire underground world shook, and rubble fell!

The shock wave even stirred up a wall of dust, which spread sharply in all directions, and a stone pillar more than ten meters thick at the nearest distance shattered in an instant.

As for Song Anran, it was as if he had been kicked hard by a giant, flew dozens of meters, crashed into a supporting stone pillar, smashed out a big pit, and embedded it inside.

But the giant worm was not having a good time, and it also took a few steps back, shaking its head vigorously, and letting out a painful hiss.

At the base of its long horn, there are directly fine reticulated fissures, and white liquid slowly oozes out, but the long horn itself is still intact.

Song Anran finally broke free from the stone pillar and fell to the ground, unable to be surprised!

For him, this is the first time he has encountered the real thing that can resist the long bone knife with the gray shadow attached!

He glanced at the long bone knife, and there was a peanut-sized gap on the blade, and the blade also had cracks!

Song Anran was distressed, since he had fought with it, he had never suffered such serious damage.

Fortunately, there is a gray shadow, which can make the long bone knife recover slowly!

Even so, Song Anran still sent the Long Bone Knife into the dimensional space, and if there was another such impact, the Long Bone Knife would have to be shattered!

If it breaks like that, he's not sure, and the Gray Shadow can be repaired!

Now, in Song Anran's hand, there is a long bone knife transformed into a gray shadow!

He waved his hand and pointed at the giant worm again!

The giant worm's eyes became even redder, and it sped up and lowered its head to rush towards him again.

With a wave of Song Anran's hand, the silk thread entangled one of the giant insect's arthropods, and at the same time, it also exerted force under his feet, bounced over like a cannonball, and slashed at one of the giant insect's arthropods with the Gray Shadow Long Bone Knife.

The arthropods of the giant insect also have a thick layer of silver-gray carapace, which is harder than steel, but compared to its antennae, it is very weak.

Song Anran's knife also made a sound of metal colliding, but it was accompanied by a click!

The hard shell of the giant insect's arthropods was shattered, and pieces of it peeled off, and the silver-gray steel pillar-like arthropods were cut off in half by Song Anran!

The giant insect is huge, and its sensitivity can catch up with Song Anran!

He scurried around, and in a few clicks, he cut off all four arthropods on the same side of the giant worm!

The giant insect struggled and writhed, but how could it move effectively with only one side of the arthropod!

At this moment, the carapace on the back of the giant insect suddenly cocked, stretched out its wings, and flapped it at great speed, and the giant insect suddenly flew up!

Song Anran was stunned, "Forked, I forgot that it can fly!"

It's no wonder that Song Anran would forget this stubble, such a huge insect, who would have thought that it could still fly, especially in a small space like an underground cave!

The giant insect was condescending, staring at Song Anran, and let out a low hiss, and the sound wave of the Dao Dao was transmitted far away!

Song Anran's face changed suddenly, and he heard countless buzzing wings coming from all directions, this is a giant insect calling for help!
