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

Could it be that this hole also leads to the underground world?

Xu Xin looked into the cave. Even though he had the night vision ability of red berries, he still couldn't see to the bottom. It was still pitch black below.

He leaned down and grabbed a handful of soil at the entrance of the cave.

[Contaminated soil (ash): Soil infected by unknown forces, useless to survivors. 】

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

Is this hole originally there?

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

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

In the second stage, they may start to really come into contact with the underground world!

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

He didn't dare to jump in like Changyin and the others. Who knew how deep the cave was. Changyin's family were made of rocks and were insensitive to water pressure. They could jump in, but he couldn't.

By the lake, the three beasts were still waiting. Coco poked her head on the rocks by the lake, looking worriedly at the lake, which had been motionless for more than ten minutes.

After seeing Xu Xin's figure heading upstream, it finally breathed a sigh of relief and called out "嘤" to indicate to Xu Xin that it was here.

Xu Xin followed the sound and looked over, and found that the three beasts were no longer in their original positions. They were now on the other side of the lake, while Silver King and Mimi were scratching something on the ground with their claws.

What happened? Why did you get there?

Xu Xin swam over and walked up from the lake.

My body is wet, but fortunately the scale armor does not absorb water. It is almost noon now, the sun is just right, the weather is hot, and the air is not humid, so the water on my body will dry up in a few minutes.

Walking to Yinwang and Mimi, Xu Xin found that they were still digging.

"What's wrong? Is there anything down there?" he stepped forward and asked.

"Hey!" Coco waved her little paws at him, gesturing something.

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

"Hey!" Coco nodded.

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

"Hey!" Keke puffed up her small chest, then climbed up Xu Xin's arm and onto his shoulder.

At this time, Silver King and Mimi had dug out half of the altar knife. The knife was inserted into the ground with the tip downwards. It seemed that it should have been thrown directly in. It was not impossible with the strength of the long seal.

Pulling out the altar knife, Xu Xin glanced at the bottom of the lake with some concern.

I don't know what's going on with them. Let's wait and see again in the evening. Maybe the altar will really change.

Riding on the Silver King, Xu Xin first came to the altar and put the altar knife back to its original position to avoid provoking more monsters.

There was nothing left to explore around, so he started walking back.

Return the way you came.

When passing near the salt mine, he subconsciously glanced at the salt mine.

It doesn't matter if you don't look at it, as soon as he looked at it, he broke into a cold sweat.

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

"Ouch!" Silver King turned around and arrived at the mine in a few seconds.

The entrance to the cave that was originally blocked by Xu Xin with a large rock was opened for some unknown reason!

The rocks blocking the entrance of the cave had disappeared at this time, and he did not find them near the entrance of the cave.

Looking inside the mine, everything in the mine is still so normal, it looks like a completely ordinary mine.

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

The ground is too clean.

Where have the broken vines just now, the crossbow bolts he shot into them, and the debris of stones and salt mines on the ground gone?

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

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

Xu Xin thought of something, and his expression suddenly changed. While observing the hill where the salt mine cave was located, he backed away. Slowly, the overall appearance of the hill was revealed in front of Xu Xin's eyes.

"I...fuck..."

Xu Xin's complexion changed drastically, and his whole body became cold.

He wouldn't be able to figure it out without thinking in a certain direction. This association suddenly caused a chill to rise from his heart.

If you think of this hill as a huge head, then this mine is just its big mouth!

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

Gu Yan

Continuing to look up, the two concave pits on the hills happen to be at the position of the eyes, just like eye sockets!

And above each pit, there is a tree that grows very crookedly on the slope. From this angle, it happens to be the two raised eyebrows above the eye sockets!

The more I look at them, the more they look like me, and the more I think about them, the more they look like me.

He wanted to convince himself that this was just a coincidence, but combined with the previous situation, the inside of the mine would heal automatically, things inside and outside the mine would magically disappear, and the mine would not even be protected by the tree house...

The possibility of coincidence is really slim.

By the way, the deep pit inside couldn't be the esophagus of the big monster! Maybe it ate the rocks around 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 calmed down her mood a little.

When he thought that he might have mined salt in the mouth of a giant monster, he still felt his hands shaking a little, so he quickly ate a strawberry (blue) before calming down.

After calming down, he not only laughed out loud. He really looked like a drug addict.

No, you can’t rely too much on the effects of strawberries in the future. You still have to learn to control your emotions on your own.

"Huh?" Coco called out confusedly on his shoulder, expressing confusion about his behavior.

Xu Xin suddenly wanted to tease Coco.

"Keke, look, does this hill look like a human head?" Xu Xin took Keke down and made her face face the direction of the hill.

Coco was confused by Xu Xin's words and could only look at Qiuling in confusion.

"Ugh?...Ugh!" Coco tilted her little head and remained motionless at first, but when she saw clearly, she was so frightened that she broke away from Xu Xin's hands and hung them on his back again.

Even so, it couldn't help but stick out its little head and look towards the hills.

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

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

Silver King bared his teeth in the direction of the hills and let out bursts of shouts from his throat. Mimi arched her back, her whole body was full of fur, and her tail was swaying slightly behind her back, as if she might attack at any time.

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

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

A hill sixty to seventy meters high is just a head. Even if this giant has a seven-headed body, the overall height is between four hundred and five hundred meters!

Four to five hundred meters is the height of the Pearl of the Magic City, the Yangcheng Tower, and the overall height is much wider than the slender building.

If it really does appear, the visual impact will be absolutely unparalleled.

The blood-striped troll Xu Xin had seen near here before was only thirty or forty meters tall.

Good guy, co-author, he underestimated the hills in this circle before? How can the blood-striped troll be compared with such a giant monster?

Looking at the mine with mixed emotions, Xu Xin turned over and sat on the back of Silver King: "Let's go, let's go to the black bear cave and have a look."

Go find the giant crocodile to see if it can protect itself during the rainy season. Moreover, he can also ask the giant crocodile about the questions here. Although he can't understand it, Coco can understand it. When the time comes, let him

Just 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 screen all possibilities.

As for this, Xu Xin has no way to deal with it, so what else can he do, just try not to provoke him.

When you go to the altar in the evening, stop by to check on the situation. Maybe some different things will happen here at night.

Silver King was very fast, and within a few minutes, one person and three animals arrived at the creek outside the Black Bear Cave.

Xu Xin was shocked to find that there was only a 20-meter-long crocodile-shaped pit left at the bottom of the lake. The rest of the creek was tens of centimeters and less than a meter deep, and only this crocodile-shaped pit was several meters deep.

It's like digging a reservoir in the middle of a stream.

This is obviously where the giant crocodile once lay.

...not here anymore?
