Zheng Guo crouched on the back of the bear king, grabbed its hair, buried his face in its fur, and protected the back of his head with his arms.

It stinks so badly that I don't know how long I haven't taken a shower.

There was the sound of ice cracking behind him, and the entire ice cave was shaking, and the scene was chaotic.

Zheng Guo's muscles were tense all over his body, ready to meet the impact at any time.

However, the expected collision did not come, with the bear king opening the way, any obstacles are not worth mentioning.

Click......

With a few crisp sounds, the bear king roared and smashed into an ice pick, and suddenly fell into the air and fell straight down.

Zheng Guo felt weightless, and immediately transferred his internal breath to protect his internal organs.

Bang!

Even with the soft fat of the bear king as a buffer, this blow still made him stumble, his eyes dizzy, and his ears buzzed.

Zheng Guo slid off the bear king's back in a daze, supported its body with one hand, and shook his head to quickly sober himself up.

The senses are gradually returning.

The first is hearing. The bear king roared beside him, the sound of running water was close to his ears, and there seemed to be a loud bird's cry from above.

Slowly, the line of sight gradually became clearer.

The first thing you see is a large area of faint blue light, covering almost the entire area in the field of vision.

The river he had in mind was ten meters away, winding in front of him, and the surface of the water reflected blue light.

The blue light is beautiful, but the full-screen blue light like this is a bit too much, which makes people feel like they are chilling in their bodies, as if they have accidentally broken into the Netherworld.

Zheng Guo blinked vigorously, feeling a little incredible.

The touch under your feet was a little soft, and it was definitely not ice.

Zheng Guo looked down at the soles of his feet.

He was standing on a meadow surrounded by glowing weeds. Zheng Guo picked up one and looked at it carefully for a moment, there was nothing special, it was similar to Dongming grass.

At this time, the camera turned upward, and a little blue light flickered on the top of the pitch-black cave, like a cosmic starry sky.

The audience realizes that it is a huge ice cave overgrown with glowing plants.

Zheng Guo looked at the scenery in front of him, thought for a moment, his eyes lit up, and said: "Sailors, I didn't expect that there would be such a small world under the ancient ice. You may think that this is not logical, but in fact, it is possible, the reason is very simple, as long as I give a little hint, I believe you will suddenly understand. ”

Zheng Guo looked at the screen with a smile, waiting for the sailors to ask questions impatiently.

"Definitely a fairy mansion (☆_☆)"

"It's also the Immortal Mansion, how do I feel a little weird, it looks like it's going to be haunted. (*￣rǒ￣)”

"According to Lao Gao, this should be the legendary underworld (; ￣ェ￣）”

", look, the ghost is up?!"

"Guoguo, what are you laughing at, scared Ben Meng to death⊙Д⊙"

……

Zheng Guo put away his smile and said, "Aren't you curious why there are living water and plants here?" It's a glacier at minus 20 degrees Celsius, so it's strange to see a small ecosphere. ”

"Not curious⊙ ω ⊙"

"Love to say it or not⊙ω ⊙"

"Hahahaha, don't ask, you can't hold back what you'll say anyway. (￣y▽￣)~*”

"We're already immune←_←"

……

Zheng Guo shook his head, thinking that it seemed that he would have to change his routine in the future.

"The surface temperature here is above freezing, so there is living water and plants." Zheng Guo squatted down, pressed his hand to the ground, felt it, and nodded, "Remember what I said before?" Mt. Shirasawa is an extinct volcano. As many of you probably know, volcanic areas are prone to geothermal resources. This small subglacial ecosphere must rely on a steady stream of geothermal energy input to sustain its existence. ”

"I see; ￣ェ￣）”

"There is yin and yang, yin and yang are balanced, but it is a good place to cultivate. Thanks to Xiaoyou for helping me find it, the old man will go to retreat tomorrow. As a sign of respect, I will give you a box of immortal medicine, please send a private message to my address. ”

"Good routine upstairs."

……

Zheng Guo's expression was much more relaxed, and he walked towards the river, saying as he walked: "The flow of this river is not small, and there is ninety percent certainty that you can go out if you go downstream, but you may have to return to below the snow line again." ”

King Xiong followed Zheng Guo's side, like a bear who had nothing to do, as if he didn't feel guilty at all about the disaster just now.

Although Zheng Guo was annoyed with it before, but after thinking about it, it was also trying to survive, and he couldn't blame it for it.

Zheng Guo's philosophy may not be quite the same as that of ordinary people, and he believes that humans and animals should be on an equal footing. He can hunt wild beasts in order to survive, and wild beasts can also eat him in order to survive, everyone is under the absolute rule of the laws of nature according to their own abilities, no one can say who is cruel, survival is the king.

So since he and the bear king have survived, there is no need to be angry anymore.

When I arrived at the river, I found that the river was wider than expected, five or six meters, and the water was very fast, no wonder the sound of the water could be heard so far.

It is not that such a rushing river will disappear, but the most likely scenario is that the flowing water spreads all the way out of this ice cave and flows all the way down the mountain.

Zheng Guo looked at the upper reaches of the river, and a thought couldn't help but pop up in his mind: If you go upstream, what can you see? Will there be an exit?

My heart itched again.

I don't know if it's obsessive-compulsive disorder, every time he goes to a secret place, he always wants to explore it carefully, and he doesn't want to let go of a corner.

Most of the time this behavior is doing useless work, but if you don't do it, you always feel uncomfortable, like you've missed something.

Zheng Guo was entangled for a moment, and quickly made up his mind: "Let's go, go upstream and have a look!" ”

Let's walk upstream along the river.

Although the cave is full of glowing grass, this blue light is not very friendly to the human eye, and it is not very clear to distinguish the scene, and walking in this environment is similar to walking at night.

So Zheng Guo walked very cautiously.

Like a loyal guard, King Bear followed Zheng Guo's side, roaring from time to time, and he didn't know what he had found.

The water is getting faster and faster, the terrain is starting to climb, there are fewer weeds, and a lot of rock is exposed.

At this time, King Xiong suddenly stopped and yelled at Zheng Guo.

Zheng Guo looked back at it, inexplicable.

Could it be that some danger has been discovered?

Zheng Guo immediately pricked up his ears and listened carefully.

Sure enough, there was a movement in front of the left.

Zheng Guo immediately became alert, held the stick horizontally in front of his eyes, and assumed a defensive posture in the direction from which the voice came.

Zheng Guo squinted his eyes to see, but he couldn't see anything, it was too dark.

Could it be that there will be some fierce beasts in this hellish place,

Unlikely, this ecosystem is fragile and unlikely to breed large predators.

But seeing the appearance of the bear king as if he was facing a great enemy, it seems that he should not be underestimated.

Rustling......

There was another strange noise, this time which even the audience could hear clearly.

Zheng Guo is now equivalent to a half-blind man, and can only rely on hearing.

There was a stalemate for a while, but nothing came over.

Zheng Guo was impatient and took a step forward tentatively.

Roar!!

The bear king suddenly let out a loud roar behind him, and the echo was so loud that it almost scared Zheng Guo to his feet.
