The fishy wind set off huge waves one after another, bringing up icy splashes, almost as high as two people, and rushed towards Ren Yi at the end of the road one after another!

"What's going on?" Ren Yi was shocked and suspicious, desperate, and half cold.

"How did the Hell Dragon King end up here......

"Could it be that Lao Li and Fax have already been killed?!"

The dragon's one-eyed eyes stared at Ren Yi tightly, and its huge body began to crash towards the small holes in the corridors!

Rumble! Whoa......

The tunnel shook one after another, and under its sharp thorns, layers of lava were extremely brittle, collapsing one after another, devastation.

Its roar continued to release strong radiation ripples, colliding with each other in the narrow and distorted space, like a whirling scimitar, carving out grooves in the stone wall, and the rocks flew wildly.

Ren Yi's mind was blank and he couldn't think. Mechanically lit up the "round sky", and poured his thoughts into the fax and Lao Li's name continuously, but it seemed to be thrown into a bottomless sea, without the slightest response.

"They ......," Ren Yi's lips trembled.

"They're gone!"

The picture in front of Ren Yi's eyes was quickly blurred by the tears that welled up.

Boom......

The vibrations in front of him continued to be heard, and all kinds of stalactites hanging above the caves broke and collapsed, falling like swords hanging in the air. Hanging on the ground, the bell rattled, piercing deep dents, smoke and dust, and debris flew.

The dragon roared weakly, half a life left. The huge head was already covered in wounds, and all the large and small eyeballs were broken, leaving only one, emitting a terrifying red light, and the other was only a black hole in the eye socket, which was bleeding for a long time. The horns on the top of his head were all broken, the scales turned out, and his body was covered with wounds of all sizes, revealing the flesh inside. The magma, which has completely solidified and dried up, hangs on the skin. The cave is small, full of hanging stalactites and jagged rocks that look like blades. The huge "Hell Dragon King" crawled forward with thousands of tiny feet wriggling. But it was so large that wherever it passed, the dried magma on its body was hooked by the stone wall, and the wounds were reopened, and the blood flowed and pooled into the groundwater.

In just a short distance, Ren Yi felt a strong fishy smell from the water surface rushing over, and when he looked down, the color of the water had turned a turbid crimson.

Ren Yi said secretly in his heart, "It seems that Lao Li and Fax have really made it suffer a lot."

Thinking of the two, Ren Yi gritted his teeth tightly, and the anger in his heart rose again. With his backhand, he pulls out the heavy sword "Elephant King" from his back.

The dragon couldn't move underground, and its whole body was trapped in a rocky cavern, stuck and unable to move.

It was ramming hard, trying to use brute force to collapse the stone wall layer by layer, forcing itself to open a path.

Suddenly, there was a bang in the cave in front of Ren Yi's eyes, and the dragon's mouth slammed out, and the stone chips rattled.

It was blocked from view by the cave, and Ren Yi's movements were completely invisible. At the same time, its mouth coincided with the stone cave, and it could not be pulled out for a while.

Ren Yi's eyes widened, "This is an opportunity!"

Swish!

Ren Yi raised the heavy sword in his hand, stepped on the water, splashed a one-person-high splash, and rushed towards the dragon with all his might!

Hearing Ren Yi's footsteps, the dragon began to writhe violently. But it didn't have much strength left, and its mouth opened twice, revealing a slit tightly.

Click, click...... Ren Yi is getting closer and closer!

Grunt......

The "Hell Dragon King" suddenly let out a strange muffled sound in his throat, and the skin under his neck quickly bulged into two huge membrane bubbles.

Rumble!

Ren Yi was running rapidly with all his might, when a burst of high temperature suddenly rushed towards him, and the air in front of him suddenly expanded by heat, like an explosion in the flat ground!

The "Hell Dragon King" spews a burst of fire in his throat!

Ren Yi was immediately swept out by the qi wave, and the high temperature instantly locked his airway, and the skin on his face was extremely painful, without the slightest

Defensively, he spun around in the air a few times, and fell back into the water with a thud.

Bang bang bang!

A loud bang came one after another, the high temperature wave detonated in the narrow cave, the air suddenly expanded, and a piece of the cave roof collapsed, and large and small stalactites fell to the surface of the water one after another, like a series of bombs falling, and the water splashed into the sky!

Ren Yi was immediately pressed to the bottom of the water.

Tiny bubbles flew up everywhere, and he held his breath in pain. After a while, the burning sensation on his body finally subsided, and Ren Yi surfaced again.

"Not good!"

Looking up again, his heart suddenly tightened!

After the dragon spewed flames, the cavern that held its head in place collapsed in the chaos, and it was now half a body that could move!

Whew......

There was a creepy creep sound from all sides of the cavern, the sound of its myriad fine, sharp claws rubbing against the rock walls.

In just a few minutes, it's a long way forward!

As soon as Ren Yi surfaced, he was targeted by the crimson resentful gaze again, the dragon's neck shrank back, the drooping skin under it quickly bulged, and the fire faintly leaked through the gaps between the teeth.

"It's coming again!"

Ren Yi's figure shrank and immediately disappeared from the water.

In the next second, a fireball erupted, the water surface boiled and exploded, and the stalactites on the top of the cave melted under the high temperature and dripped into the water.

Ren Yi's figure flickered, revealing in the darkness above the cave. He clung to a stalactite, motionless.

Below, after the water surface subsided, the dragon did not find Ren Yi, and became even more angry, its nose spurting hot air, blowing the water surface upside down. It spun up and down with its neck high, searching for Ren Yi's figure in every corner.

Ren Yi kept pondering above.

"Jumping from this angle, it has a deep wound in its neck, and if I slash it one after another, I might be able to cut off the neck bone......

With a loud bang, the dragon's body fell from the riverbed, and the earth shook.

Then, its body began to twist around the entire cave up and down, left and right, and the rocks, large and small, were surrounded by its body, as if they were infinitely extended, endless.

The dragon began to climb as if it were up.

Ren Yi was shocked, he himself hid on it, and it was easy to be discovered!

Moreover, once its head is out of the optimal angle, it is not easy to cut off the neck bone!

This...... Ren Yi clenched his heavy sword, considering whether to rush out now.

Squeak ......

Suddenly, something sounded in the dark water. It was deafening in the silence.

Ren Yi was confused.

At the same time, the dragon also heard the voice, and was attracted to all its attention, and immediately turned its head away, staring closely into the depths of darkness.

Rattle...... Whoa......

It is a screeching sound made by the cold contraction of metal after it expands violently. At the same time, there is the constant sound of water slapping.

"It's the door to the lab!!" Ren Yi was shocked.

Obviously, the dragon also found out, gave up the search for Ren Yi, and began to swim towards the depths of the waterway where the sound came.

"No, it can't be allowed to find ......."

"Otherwise, all the efforts made so far will be in vain!"

"This is the only hope for humanity......

"Hey!"

Ren Yi suddenly shouted.

The dragon was engrossed in his advance, and when he heard a loud shout, he instinctively became vigilant, stopped where he was, and raised his head to look at the dark dome.

Swish!

Suddenly, a silver-white sword light slashed, Ren Yi roared, and resolutely jumped down!
