Due to the reduction in personnel, although Rocky and the others became more cautious than before, they moved much faster, and it didn't take long for them to fall far behind the entrance to the cave.

At this time, they had completely entered the cave**, and the surroundings had already become pitch black, and if it weren't for the lighting provided by the battle armor, they wouldn't even be able to see the road clearly.

"How did this place come to be?"

Caught in the middle, Tussaud couldn't help but ask as she looked at the surrounding caves as she followed Rocky.

In her eyes, the cave didn't seem to have formed naturally, as if something had been drilled out, but she couldn't imagine what could do that.

"My lord, could this place have anything to do with Cassin City?"

"I don't know, but it's possible. ”

Hearing this, Rocky, who was cautiously moving forward in front, did not look back, but clearly heard it: "Since Cassin City has built such a huge place under the city to study the mobile fortress, there may be a similar research institute built elsewhere. ”

"I don't think so. ”

At this time, Lilia also spoke: "The purpose of Cassin City's underground research institute is to build a mobile city, and later the plan was reduced to build a mobile castle instead, there is no reason for them to build a similar research institute under the Red Water Lake, do they want to take the entire lake away?"

"Hmph, who knows, the people of the Land Era have very big brains, God knows what they are thinking. ”

Lilia's words made Rocky laugh and sigh heartily.

The people of the Land Era have suffered a serious blow from the demons, and have reached the level of extinction, under this huge pressure, their wisdom and creativity are completely incomparable to the current sky, such as the great invention of Sky City, for example, the Sky Demon Battle Armor, one of these two inventions was invented nearly a hundred years ago, and the other was invented sixty or seventy years ago, and even the magic runes that also caused a sensation in the world were invented in the Land Era, but after such a long time, did the people in the sky make any great inventions？

Apparently not.

More than a hundred years have passed, and people have been in the sky for so long, and they have not invented a new thing comparable to Sky City and Sky Demon War Armor, which I don't know if this is a kind of progress or a kind of regression.

"Have you noticed, it's been a long time since you've found a body. ”

Just when Rocky and the others were getting more and more off-topic, He Nan brought the topic back on track in time and raised a very critical question.

And as soon as he said this, Rocky and they also noticed that since the previous battle was over, they had gone hundreds of meters deep into the cave, but they didn't see a single skeleton along the way.

Before, as soon as they entered the cave, they saw a strange skeleton and were attacked by beetles, but now that they had walked for so long, they had not seen any skeletons, which was a little too strange.

You must know that before them, the Huoteng tribe had sent people to explore this cave more than once, although it was more than ten years or decades ago, but since none of the orcs who came to explore left the cave, their bones should all be here.

So it shouldn't be that you haven't seen the bones left by the orcs for so long, that's hundreds!

"Chief Honan, you ...... Look!"

Realizing this, Rocky just wanted to ask Honan's opinion, but before he could finish his sentence, he saw a skeleton.

However, after seeing this skeleton, instead of being reassured, Rocky and the others gasped, because this skeleton was embedded in the cave wall!

Looking at the light shot from the shoulder armor of the White Demon Battle Armor, you can clearly see that the bones of the orcs are deep in the dirt of the cave walls, and it feels as if they have become fossils, which is very weird.

"This ......"

Seeing this skeleton, Rocky was stunned, he only had one question to ask now, and that was how did this skeleton get into the cave wall?

If the orc leaned against the wall before he died, then even if his body was rotten, the bones should be leaning against the wall, not directly sinking into it.

This...... What the hell is going on?

I have to say, this cave is really full of weirdness, don't say what secrets are hidden in the cave itself, even the orcs who died here are also confusing, although the orcs found before were only a skeleton but as if they were petrified, and now the bones of the orcs found are deeply trapped in the wall, how did the orcs who came here to explore die before, and what did they encounter before they died?

"Rocky, look......"

While Rocky was staring at the orcs in the wall, Lilia suddenly called out to him, and Rocky, who heard Lilia calling himself, turned his head and saw that Lilia, Hernan, and Tussaud had already walked in front of him.

And when he caught up with the three of them, he was stunned.

He stood behind the three of them and stared blankly at the cave wall in front of him, and what he saw was a row of orc bones stuck in the wall!

"So many ......"

Looking at the cave wall in front of him, no, at the row of orcs sunk deep into the wall, Rocky opened his mouth wide and was dumbfounded.

Before, they were still talking about why they didn't see the bones of the orcs, but now that they have seen it, not only have they seen it, but these orcs have all sunk into the wall without exception, just like the bones just now, and it feels as if they have formed a terrifying fresco with their bones.

And counting carefully, Rocky found that there were a total of eighteen skeletons in front of him deep in the wall, and if you add the one you saw before, it is nineteen, and if you add the one you saw for the first time, it is exactly twenty.

"This is the team that came here twenty years ago to explore. ”

Just as Rocky had just counted the number of orc bones, Honan spoke: "I remember that twenty years ago, the leader sent a team to explore here, and there were exactly twenty people sent at that time, so if nothing else...... These are the people in front of you. ”

Looking at the bones trapped in the wall, He Nan said slowly.

"It's ...... them" Hearing He Nan's words, Rocky looked at the wall again, and then his face changed: "Be careful!"

As he spoke, Rocky directly clenched the Demon Fang Scythe, and when he reminded him like this, the others also reacted, He Nan immediately picked up the war hammer, Lilia and Tussaud also showed their weapons, and the four of them instantly wrapped up back to back, looking around cautiously...... 2k reading web
