In the last section of the underground river, the riverbed suddenly narrowed and the water flow became more turbulent.

Li Kuiyong took out the rope and tied Gawa tightly to the canoe. The other end of the rope strung the other four people again to avoid being dispersed by the torrent.

Hu Bayi smiled and said:

"Kuiyong, we are grasshoppers on the same rope again...ah..."

Before he finished speaking, a large vortex suddenly appeared on the river surface. Several people hugged each other tightly, squirted into the center of the vortex...

With the exclamation of several people, they fell into a huge underground river with a "thump". With the help of canoes and ropes, everyone quickly surfaced. The water temperature in the river was very high, and it was even a bit hot.

Looking up, countless tributaries like the river we passed just now spewed out of the mountain walls, like large faucets, converging into the main river below.

There are many raised stone holes on both sides, and white high-temperature gas is constantly emerging, and some dark red flame slurry is also found in the cracks of some rocks.

Li Kuiyong smiled and said:

"Shenxian Luo is right. It seems that this is really an underground volcanic belt!"

Luo Ning's glasses were covered with mist and she could not see anything. She wiped her face and said unhappily:

"I still have the intention to joke, and it's all cooked in a while!"

There was a red lava lighting nearby. The instructor stretched his neck and looked at it, pointed at a huge rock by the river and said:

"Let's go over there!"

Everyone tried hard together, pushing the canoe and struggling desperately in the rapids, but at this time the wood became a burden and was washed away after trying several times.

Li Kuiyong had to loosen his ties for Gawa and swam forward with Hu Bayi. The canoe was swept away while spinning. The five people fluttered for a while and finally climbed onto the rock. They suddenly realized that even the stone was warm.

Hu Bayi spat and said with lingering fear:

"Did you see clearly? What exactly was behind just now? It was so scary when I heard the noise, so big!"

Gawa has been on the boat all the time, and was in a state of energy at this time. She wiped her face and stood up to check the situation in the nearby river:

"Oh, I saw that Ga Xiong, followed behind them and fell into the middle of the river..."

Turning back and laughing:

“Has it been washed away?”

After saying that, he turned around and was about to come back. Suddenly, a big blood-red tongue stretched out from the river, which was more than two meters long. He swept it and wrapped his legs around, put him on the ground, and pulled him into the river!

Li Kuiyong jumped over, pulled out his waist knife, shouted and slashed hard on the scarlet tongue. With a "click", sparks splashed on the rocks, and the tongue broke in response to the sound, and the dirty blood shot out. The monster let out a shocking howl.

Li Kuiyong took advantage of the situation and pulled him back.

The monster retracted half of his tongue, howled, climbed up, staring at two strange eyes that looked like red lights, and spitting blood foam and sewage from his mouth.

It looks exactly the same as the salamander that was shot dead by a big man. It looks like a frog and its body is like a skinless crocodile, but its size is incomparable. It is more than ten meters long and its body is shining with colorful scales.

Hu Bayi turned his head and said:

"Mr. Luo, are you sure it doesn't hurt people? Why is this so big?"

Luo Ning's face was pale, she shrank behind Li Kuiyong and said tremblingly:

"I...I mean the last one...this...this is just...the overlord salamander, very aggressive...it was extinct during the ice age. I didn't expect that there would be some isolation from the world..."

Underground creatures like salamanders are cold-blooded animals. The excessive geothermal heat makes this overlord salamander extremely violent, and loses half of its tongue. The smell of blood in its mouth makes it strongly aggressive.

At this time, his big tail, which was seven or eight meters long, flicked and stared at everyone fiercely.

The instructor raised the gun and turned his eyes. Hu Bayi and Ga Wa understood each other and surrounded the two sides of the Overlord Salamander. The three-person fighting team formed a clamping force.

Li Kuiyong jumped forward and whispered:

"Instructor, this thing is invincible. You three protect Luo Ning and climb to a high place. I'll delay here for a while... By the way, give me the grilled fish!"

The Overlord Salamander screamed, opened his teeth and claws at everyone, swept his huge tail, Li Kui jumped back and dodged away, and threw out the three grilled fish on his back, which was just thrown into its mouth.

The instructor said:

"Hu Bayi, Ga Wa, you take Luo Ning away first!"

The Overlord Salamander had something in her mouth and was stunned for a moment. She opened and closed her mouth and swallowed the grilled fish whole. It seemed that it tasted good. She spit out half of her tongue and swung it, but it pulled it to the wound and howled violently again.

At this time, Hu Bayi and Ga Wa threw the grilled fish to Li Kuiyong and had already pulled Luo Ning to climb the mountain wall, but here was full of volcanic rocks and ash. It was soft and slippery when they stepped on, and it was very difficult to run.

The Overlord Salamander pounced forward, and Li Kuiyong threw out another bundle of grilled fish, but instead threw it into its mouth, it hit its tail.

The Overlord Salamander tasted the sweetness, and left them without hesitation and turned back to eat grilled fish.

Li Kuiyong took the opportunity to climb the cliff with his instructor.

Five people used their hands and feet together, and the more they climbed, the higher they were, the faster they were, and the faster they reacted. The grilled fish that Li Kuiyong threw for the third time and the fourth time was swung into his mouth by his tail, which did not play a role in delaying time at all.

Seeing the Overlord Salamander wandering on the mountain wall like a big lizard and following him, it had sharp claws and it was not difficult to climb. In a blink of an eye, it was less than two meters away from Li Kuiyong who was at the end. Its half of its tongue was almost licking its butt.

Li Kuiyong swung his waist knife into a ball of white light and shouted anxiously:

"Instructor, grenade!"

The rest of the people thought at the same time that there were two grenades that had not been used. At this moment, the instructor had one, and Gawa had one in the armed belt.

The standard wooden handle grenades they used are all waterproof. Some soldiers stationed in Qinghai Lake often use grenades to fry fish in the lake. Although everyone fell into the water just now, the grenades should not be damp.

The instructor took out the grenade:

"Kuiyong, caught it."

Li Kuiyong threw it from the oblique direction. Li Kuiyong quickly inserted his waist knife back to his waist, and used his right hand to catch the grenade, pushed off the safety cover with his thumb, and pulled off the pull ring. The fuse of the grenade was ignited, and white smoke came out.

He looked at the bloody mouth of the Overlord Salamander and threw the grenade in!

The Overlord Salamander saw the black flying over, thinking it was grilled fish again, so he happily swallowed it.

Although the skin on its body is hard, the flesh in its mouth is very soft. As soon as its mouth closes, a loud "boom" sound was heard, and its head exploded from the inside to the outside, and its huge body fell under the stone wall.

After twisting a few times, he died on the rocks by the river with his white belly.

Li Kuiyong let out a long breath, and suddenly the mountain wall swayed violently, and he was so angry that he punched the mountain wall-
Chapter completed!
