After the salt mine cave, this is the second bottomless hole he found today.

Could it be that this cave leads to the underground world?

Xu Xin looked into the cave. Despite the night vision ability of Red Currant, he still couldn't see it, and it was still pitch black below.

He bent down and grabbed a handful of soil at the entrance of the hole.

[Contaminated soil (ash): soil contaminated by unknown forces, is useless to survivors.]

Sure enough, it’s this kind of soil again!

Is this hole there originally?

Thinking of the newly appeared cave in the salt mine cave, Xu Xin seemed to understand something.

Perhaps, these caves that connect the underground world may be related to their second stage of survival.

In the second stage, they may start to truly contact the underground world!

Xu Xin took a last look at the deep cave in the lake and turned around and swam back to the lakeside.

He didn't dare to jump in like Long Seals. Who knows how deep it is under the cave? Long Seals are stones, and they have no sense of water pressure. They can jump down, but he can't go down.

At the lakeside, the three beasts were still waiting. Coco leaned his head on the rocks by the lake, looking worriedly at the lake surface where there was no movement for more than ten minutes.

After seeing Xu Xin's upstream figure, it finally breathed a sigh of relief, and shouted "screaming", indicating that Xu Xin was here.

Xu Xin looked at the sound and found that the three beasts were no longer in their original position. They were on the other side of the lake at this time, while Silver King and Mimi were digging something on the ground with their claws.

What happened and why did you get there?

Xu Xin swam over and walked up from the lake.

My body was wet, but fortunately, the scales did not absorb water. It was almost noon again, and the sun was just right, the weather was hot, the air was not wet, and the water on my body would be able to dry in a few minutes.

Walking to the side of Silver King and Mimi, Xu Xin found that they were still digging.

"What's wrong? Is there anything below?" he asked.

"Wow!" Coco waved his little claws at him and gestured something.

"A knife?... an altar knife?" Xu Xin's eyes lit up, "Did you find it?"

"Yeah!" Coco nodded.

Xu Xin reached out and rubbed Coco's little head: "It's done well!"

"Yeah!" Keke straightened his chest and then climbed up to his shoulders along Xu Xin's arm.

At this time, Silver King and Mimi had already dug half the altar knife. The knife was inserted downward into the ground with the tip of the knife, and it seemed that it was thrown directly in. It was not impossible to use the strength of the long seal.

Drawing out the altar knife, Xu Xin looked at the bottom of the lake with some concern.

I don’t know what happened to them. Let’s take a look at it in the evening. Maybe what will happen to the altar really happens to the altar.

Riding on the Silver King, Xu Xin first came to the altar and put the altar knife back in place to avoid provoking some monsters.

There was nothing to explore around him, so he began to walk back.

Return the same route.

When passing by the salt mine cave, he subconsciously glanced at the salt mine cave.

It doesn't matter if you don't look at it, but when you see it, you immediately burst into a cold sweat.

"Stop! Silver King, let's go to that mine!"

"Aowu!" The Silver King turned around and arrived at the edge of the mine in a few seconds.

The hole that was originally blocked by Xu Xin with a large piece of rock was opened for some reason!

The rocks that blocked the entrance of the cave were nowhere to be found at this time, and he did not find them near the entrance of the cave.

Looking inside the mine, everything in the mine was still so ordinary, and it looked like an ordinary mine.

But it was this ordinary thing that made Xu Xin discover the clues.

The ground is too clean.

Where did the broken vines that he shot into it, and the stones and salt mines on the ground, go?

This mine can not only repair itself, but also fail to clean it.

Could it be that something came out of it, cleaned up the mine cave, and removed the stones blocking the mine?

Xu Xin thought of something, and suddenly his face changed. While observing the hill where the salt mine was located, he retreated and slowly, the overall appearance of the hill appeared in front of Xu Xin.

"I...she..."

Xu Xin's face changed drastically and her whole body was cold.

He still couldn't see it without thinking in a certain direction. This association suddenly felt a sense of coldness rising from his heart.

If this hill is regarded as a huge head, then this mine will be its open mouth!

And above the cave, there is a ridge-like bulge, like a person's nose bridge.

Gu Qi

Keep looking up, two recessed pits on the hill happened to be in the position of the eyes, just like eye sockets!

Above each pit, there is a tree that grows very crookedly on the slope. From this angle, it is exactly the two raised eyebrows above the eye socket!

The more I look at it, the more I look at it, the more I think about it.

He wanted to persuade him that it was just a coincidence, but combined with the situation that occurred before, the mine would heal automatically, things inside and outside the mine would magically disappear, and the mine would not even be protected by tree houses...

The possibility of coincidence is too small.

Speaking of which, the deep pit inside is not the esophagus of the big monster! Perhaps it ate the stones at its mouth and the things in its mouth, so the inside and outside of the mine are so clean now!

What is this? Mountain Giant? This is too magical...

Xu Xin took a deep breath and stabilized her mood a little.

When he thought that he might have mined a salt mine in the mouth of a giant monster, he still felt his hands trembling a little, so he quickly ate a strawberry (blue), and then calmed down.

After calming down, he not only burst out laughing. He is really like an addict who has become a drug addict.

No, you can't rely too much on the effect of strawberries in the future. You still have to learn to control emotions yourself.

"Yeah?" Coco shouted in confusion on his shoulder, expressing confusion at his behavior.

Xu Xin suddenly wanted to tease Coco.

"Koke, look, does this hill look like a human head?" Xu Xin hugged Coke down and let its face face facing the hills.

Keke was confused by Xu Xin's words and could only look at the hills in confusion.

"Hehe?...Hehe!" Keke was still tilting his little head at first, but after seeing it clearly, he was so scared that he broke free from Xu Xin's hands and hung them on his back again.

Even so, it still couldn't help but poke its little head out and looked towards the hills.

Looking at Coco's cute little appearance, Xu Xin smiled and touched its little head.

Not only Coco, but also the Silver King and Mimi who heard his words also changed their attitude after looking at the overall appearance of Hills.

The Silver King bared his teeth in the direction of the hills, and bursts of crying from his throat. The breasts arched their backs, their whole body was furrowed, and their tail was slightly swaying behind them, making a look that they could attack at any time.

Xu Xin continued to look at this "head", and the more he looked at it, the more he felt amazed.

If this is just a masterpiece of nature, it would not be an exaggeration to be rated as a five-star scenic spot on the earth. But if it was really what Xu Xin guessed, then this mountain giant would be too big.

A hill that is sixty or seventy meters high is just a head. Even if this giant has a seven-headed body, it is a height of 400 to 500 meters in total!

Four or five hundred meters, that is the Pearl of the Demon City. The height of the Yangcheng Tower is much wider than that of the slender buildings.

If it really appears, the visual impact is absolutely unparalleled.

The blood-patterned trolls Xu Xin had seen here before were only thirty or forty meters high.

What a guy, he underestimated the hills in this circle before? How can the blood-patterned troll compete with this giant monster?

After looking at the mine cave in a complicated mood, Xu Xin turned over and sat on the back of the Silver King: "Let's go, let's go to the Black Bear Cave to take a look."

Go and find the giant crocodile and see if it has saved itself during the rainstorm season. Moreover, he can also ask the giant beast about the question here. Although he doesn't understand, Coco can understand it. Then let Coco translate it for him.

And he also wanted to see if there were any changes in the black bear cave. Now he was a little nervous and had to filter all possibilities.

As for this, Xu Xin can’t deal with it, what else can she do? Try not to provoke her.

When you go to the altar at night, let’s take a look at the situation. Maybe something different will happen here at night.

The Silver King was very fast. In a few minutes, one man and three beasts arrived at the stream outside the Black Bear Cave.

Xu Xin was shocked to find that there was only a crocodile-shaped pit at the bottom of the lake. The rest of the stream was less than ten centimeters deep, and only this crocodile-shaped pit was a few meters deep.

It was like digging a reservoir in the middle of a stream.

This is obviously where the giant crocodile once lies.

...Not here anymore?

He can find this giant crocodile who is very good at him and can help him at any time, but it makes him feel very safe. After all, this big guy is not as good as the giant crocodile in the middle of the lake.
