There were a few pieces of scale armor on the head of the ground crocodile dragon, and a trace of blood flowed out, and the flesh and blood on the tip of the mouth were even more cracked, broken, and the flesh was erosive.

The ground crocodile dragon demon power covers the wound, and the wound repairs extremely quickly.

The Earth Crocodile Dragon frantically rushed towards Yuan Lin again.

Yuan Lin looked at the surging earth crocodile dragon, and then glanced at the dark cave in the deep pit. There was a sudden firmness in his eyes, as if he had made a lot of determination.

With a whoosh, Yuan Lin shot out, the speed was incredible, flying directly past the ground crocodile dragon, plunging into the dark cave, and was instantly swallowed by the darkness.

Yuan Lin's speed is not comparable to the Earth Crocodile Dragon, and if he keeps chasing, the Earth Crocodile Dragon will inevitably catch up with Yuan Lin. When the time comes, Yuan Lin will not be able to escape death. When he saw the deep hole in the ground and the giant rat corpse in the deep pit, Yuan Lin suddenly had a desperate attention.

Looking at the dead giant rat corpse in the deep pit, Yuan Lin was sure that this deep hole was the passage of the giant rat. As for where it leads, Yuan Lin has not yet considered it.

Yuan Lin flew into the deep cave, the deep hole was pitch black, and he couldn't see his five fingers, but this was nothing to the spirit demon in the foundation building period. A pair of golden eyes seemed to emit a fine light, and they could see the cave in front of them clearly.

Bang~

The earth walls around the cave suddenly trembled violently, and Yuan Lin's face was shocked, and he didn't need to think about it to know that the Earth Crocodile Dragon had actually burrowed into this small deep hole.

Then, the whole small cavern, as if it did not affect its speed. Turning into a black drill, he drilled into it frantically.

The originally small cave was enlarged more than ten times.

"This king wants to see how long you can hold on?" Yuan Lin sneered on his face. After saying that, he flew faster towards the depths of the cave.

Fortunately, the rat's burrow was spacious enough, and Yuan Lin was speeding through the burrow, without feeling crowded at all.

And, as Yuan Lin descended deeper and deeper, he found that countless caves extending in all directions appeared underground, as if there was a dense transportation network underground, crisscrossing and crisscrossing.

Yuan Lin was even more sure that this was a rat hole.

In the underground cave, Yuan Lin changed the cave for a while, changed the place for a while, and changed directions at will in the cave.

Shake off the ground crocodile in this way.

However, Yuan Lin seemed to be a luminous body, exuding a light that penetrated all obstacles, no matter how Yuan Lin changed directions, the ground crocodile dragon could accurately find Yuan Lin's location.

"It's another giant rat, and the deeper it descends, the more the giant rat numbers have. These giant rats are very weird, only in the mortal demon realm, the demon beasts are not only huge, but also have rough skin and thick flesh, and their defense is extremely perverted. Yuan Lin slapped a giant rat in the cave with one palm, and galloped rapidly, still reciting words on his lips.

As Yuan Lin went deeper into the cave, giant rats poured out of the cave, these giant rats walked around the cave familiarly, and when they saw Yuan Lin, they frantically blocked Yuan Lin's way and wanted to kill Yuan Lin.

A giant rat with two is nothing to Yuan Lin. But hundreds of thousands, the hands will be sour when they are killed.

As long as a giant rat spotted Yuan Lin, as it screamed, echoes resounded in the countless caves around it.

One by one, huge numbers flocked to Yuan Lin's location.

What's more, there is a big threat behind him.

Yuan Lin had to retreat for the time being, looking for the burrows where giant rats were scarce.

Squeak squeak~

Suddenly, giant rats appeared in front of the cave, roughly estimated to be at least hundreds, blocking the front of the cave.

Squeak squeak~

Hundreds of giant rats poured out of his back.

These giant rats squinted their small eyes, and all the momentum came together, exuding a tyrannical aura. Yuan Lin's face turned cold, his hand slapped the storage bag, and the fire gourd appeared in his hand.

There were not many flames in the fire gourd, and Yuan Lin originally didn't plan to use the fire gourd.

However, in this case, using a fire gourd is the easiest and fastest way to open the cave.

Yuan Lin plugged it, and extremely high flames suddenly erupted out.

The space of the cave is a tube-shaped, such a space, once the flames are sprayed out, the flames will rush forward with the surging cave, and the flames will condense into a ball, ensuring that the flames lose their power because they are scattered.

The giant rat's burrow maximizes the power of the flames.

The cave of the giant rat instead became the murderer who indirectly killed himself.

As soon as the giant rats saw the flames, their faces changed color in fright, and they screamed in panic, and they retreated back in a panic.

However, the cave space was originally only able to allow one giant rat to pass through, and a hundred rats fell into a panic, so it was okay to retreat in order.

One by one, they ran wildly, and the more they did this, the more chaotic they became.

In an instant, flames surged up, like a wave of fire, killing all the giant rats at once, and hundreds of rats in front of them were burned to ashes.

The old trick was repeated, and Yuan Lin was also a flame against the giant rat behind him, burning the giant rat with heavy losses, and Zhang Huang fled.

Squeak ~ squeak ~ squeak ~ squeak ~

Suddenly, a miserable rat cry sounded behind him, accompanied by a loud boom.

The ground crocodile dragon is still chasing after it.

The Ground Crocodile's spinning body tore the giant rats that stood in its way to pieces. It was like there were no taboos, and it was dead in the direction of Yuan Lin.

Squeak ~ squeak ~ squeak ~ squeak ~

At this time, the sound of thousands of giant rats sounded in the depths of the cave, and the huge volume spread throughout the entire underground cave.

"This underground cave is intricate and intricate. It's more complicated than the transportation network. These caves lead to places on the ground. However, both horizontally and vertically, they all have one thing in common, no matter how they go, their direction is downward. All of this suggests that the rat's nest is deeper underground. Yuan Lin said secretly.

"This king still doesn't believe it, a huge giant rat clan can't stop you. Yuan Lin sneered. Recklessly, they galloped deeper.

After speeding for a while, a bright light appeared in front of him, and the light in Yuan Lin's eyes flickered. It's already thousands of meters underground, how can there be a bright light.

Eccentric, eccentric.

However, the rumbling sound behind him was getting closer and closer, and Yuan Lin could clearly see the blood-red and indifferent pupils of the Earth Crocodile Dragon.

No longer hesitating, Yuan Lin's body scurried forward. The momentum on the body is the largest, the martial will is draped over the whole body, the demonic power gathers but does not disperse, and the desolate monument law is also brewing. As long as there is a little danger, Yuan Lin will attack with all his strength regardless of everything.

However, as soon as he stepped into the bright light, Yuan Lin's eyes were filled with an unbelievable look of horror, and his face was even more dumbfounded.

"This, this is incredible. Everything in front of him made Yuan Lin's heart full of horror and unspeakable shock.

It turns out that the ground below the kilometer is not soil.

In front of you, there is a huge underground world. The space is incomparably vast, and it is more than enough to survive 100,000 people.

The underground world seems to be a hollowed-out underground, with caves in all directions, and giant rats in the caves go back and forth.

And the underground is a wide area. Tens of thousands of giant rats are busy. The entire underground world is filled with the sound of giant rats and the smell of rats.

Underground, there are countless corners of buildings that resemble simple minarets, and at the top of the minarets is an egg-sized pearl of the night.

Such minarets can be found everywhere on the underground ground. The list goes on.

Suddenly, several strong momentum attracted Yuan Lin's attention.

Directly in front of the underground world, there was a brilliant golden light. The golden light shone brightly, and Yuan Lin's eyes were dizzy.

It was a 100-meter-long and wide platform made entirely of gold.

On the high platform, a three-meter-high golden throne is placed.

Leaning on the Golden Throne was a large, mouse-eyed fat man.

This fat man has a huge body and very small eyes, but they are shining. He has a few short whiskers on his lips, and he tugs at them whenever his eyes shine.

"The Rat Demon. Yuan Lin's eyes froze and he muttered.
