Unable to attack for a long time, Chen Yu felt his mental strength was quickly damaged, and shouted: "The main attack on the ice skate above, buried the mud dog alive, and died of freezing."

Seeing that the mud newt seemed to be trapped by the ring-shaped iceberg, Tong Yan was overjoyed and responded loudly. The dragon and phoenix double-edged circling up and chopped the ice-slipper.

This cave is not only large in area, but the top of the cave is also extremely high. The ice skates hanging upside down from the cave are also astonishingly large. The largest can be dozens of tons, or even hundreds of tons.

The two of them deliberately chopped the ice skewers, and the ring-shaped icebergs piled higher and higher, and they piled up tens of meters in an instant.

Barking!

The mud newt roared twice, and the giant tail swept out, sweeping the circular iceberg into a huge gap.

At this moment, a huge mountain of ice fell from the sky, and it happened to hit the mud newt's huge body like a cow just protruding from the gap.

boom!

The huge ice as big as a three-story building smashed down heavily, and the whole cave trembling was shaken.

The mud newt was hit by the huge ice, and the exposed tail trembled like an electric shock. It seemed that the injury was not light.

"Go on, get more ice down!"

Chen Yu was overjoyed, and he controlled the crystal sword to continue hacking the ice skate.

After a long while, a larger iceberg piled up, and the mud newt was deeply pressed under the iceberg.

Withdrawing the crystal sword, Chen Yuqiang tolerated the dizziness of excessive mental energy consumption, and smiled triumphantly: "Animals are animals, no one is ever smart."

"Brother Yu is the smartest person in the world."

Tong Yan retracted the double-edged dragon and phoenix, and slapped Chen Yu's flattery with a smile.

Chen Yu rubbed his temples on both sides, squeezed a smile at Tong Yan, then shook his head fiercely, "This Royal Flying Sword fighting is really tiring and headache."

Tong Yan's face was relaxed, without the slightest feeling of dizziness, which made Chen Yu couldn't help smiling bitterly: "When will you have the strong mental power like you!"

After taking a break, seeing that the mud newt under the iceberg didn't make any more movement, it looked like it was crushed to death or frozen. Chen Yu smiled proudly: "You can't live by yourself, brother didn't want to kill you. Yes, but you want to kill brother, now it's okay, you will lose your life."

After finishing the mud newt, Jiang Manwu and Caixia were not seen. Chen Yu was very worried about their safety. When the dizziness improved a little, he led Tong Yan to continue on the road.

Leaving the huge cave, the two of them got into the tunnel-like ice cave again, where there was still a gurgling stream.

Continuing to wade through the water, the two of them had to relax and save a lot of effort this time, just because they were going down the river.

In the huge cave where the mud newt was, there was a pool the size of a basketball court, from which the stream slipped out.

To put it bluntly, that pool is the source of the creek, and two creeks also flow out, one to the outside of the ice cave and the other to the deeper part of the ice cave.

Chen Yu guessed that the current stream is also very likely to flow outside the ice cave, to another outlet.

After encountering a mud newt, Chen Yu became more worried about the safety of Jiang Manwu and Caixia. God knows what kind of big guy is hiding in this dark and weird ice cave.

"Brother Yu, look at the fish in the water, what a big fish, ah, it's flying!"

While walking, Tong Yan suddenly pointed forward and exclaimed.

Still a little dizzy and listless, Chen Yuwen suddenly raised his head and looked in the direction of Tong Yan's fingers. Sure enough, he saw a white flowery shadow leaping out of the water and flying.

"Damn, Mother Fish is here! Get ashore!"

Chen Yu shot down the flying blood-eating flying fish with a palm, yelling and pulling Tong Yan to escape ashore.

The flying fish that was shot down was about the size of a pigeon, and had a very bulging belly. After a few flutters, it rushed up against the current, quickly drifting away, and did not jump out of the water to attack Chen Yu and Tong Yan.

"Look, there's more!"

The shocked Tong Yan's fingers cleared the bottom of the stream and exclaimed again.

Dozens of blood-eating flying fish marched upstream in a group, swimming quickly under their noses.

Chen Yu stood in front of Tong Yan, leaning back as far as possible, away from the stream.

"It's really strange, they seem to be running for their lives, is there something chasing them down."

Tong Yan was surprised and whispered.

Chen Yu stared at the stream vigilantly, frowning for a while, and then said: "It's not that something is chasing them, they are eager to lay eggs."

"spawning?"

Tong Yanyuan opened her beautiful eyes and stared at Chen Yu in surprise and doubt, "How did Brother Yu know?"

Chen Yu smiled and replied: "Guess, they are most likely to lay eggs in the big water pool. They lay their eggs and they will flow down the river, into the ice lake, and on the way to the ice lake. Little fish will hatch."

"Brother Yu is really smart, Yan'er thinks it is very possible." Tong Yan laughed and slapped Chen Yu flattering, "Brother Yu is the smartest person in the world."

Chen Yu smiled extremely proudly, and soon his expression became solemn, and muttered to himself: "I hope they can get out of this ice cave safely, and don't encounter schools of blood-eating flying fish or other evil things."

Tong Yan smiled optimistically: "Don't worry, Brother Yu, Ji people have their own faces. Yan'er believes that sister Wu and the others will be fine. Maybe they are eating barbecue somewhere in front, waiting for us."

"With your good words, let's go..."

Before Chen Yu finished speaking, Tong Yan's expression changed drastically.

She tremblingly pointed her finger upstream and said, "It's not good, the mud dog is chasing you!"

Barking!

Before her words fell, two dog barks came over.

"Damn, haven't been smashed to death?"

Chen Yu was also shocked, and when he walked along, he encountered a mud newt. Which one would it be if it wasn't the previous one?

Run or fight?

Chen Yu instantly made the decision to flee after hearing the sound, and took Tong Yan to flee quickly.

Although it is not Chen Yu's style to flee without a fight, the mud newt is too powerful and it is really difficult to kill it.

Of course, Chen Yu didn't really run away after hearing the sound, but was trying to buy time to kill the mud newt.

He has a lot of experience in life-and-death battles with ferocious beasts. Whenever he encounters life-threatening situations, he always thinks of a strategy to "defeat the enemy".

The defense is strong, the reaction speed is fast, and it is immune to electric shock. For a while, Chen Yu couldn't think of a way to restrain the mud newt, so he could only drag Tong Yan to flee without his life.

"It's weird. Even if those big ice blocks didn't kill it, they would freeze it. Why did it escape?"

Tong Yan murmured softly while running away.

Chen Yuxin said yes, isn't the one that caught up with that one, but the other one that came out of the big waterhole?

Soon he thought of the reason why the mud newt got out of trouble. The ground temperature was so high that the ice cubes piled on it would be melted by the geothermal heat.

With geothermal heat, not only will the mud newt not be frozen to death or freezing, but it can also easily escape.

There was a rush of water behind him, and Chen Yu looked back in panic, and saw that the mud newt threw a huge splash of water in the stream, rushing in quickly, and the distance was less than 100 meters.
