What will be under the boulder?

Luo Chen didn't know why he was thinking about this question, but this question suddenly appeared in his mind.

This thick iron chain, whether it is buried in the boulder or buried under the boulder.

The thought kept echoing in his mind, and he vaguely felt that the question seemed to be critical.

However, he did not act immediately, but continued to watch Zhou Yue and the others dig a pit.

After more than an hour, the bottom of the crater was fifty meters in diameter, but they still couldn't see the edge of the boulder.

It seems that the ground under the Gobi is like a whole boulder.

But if that's the case, how did the chains get into the boulders?

Luo Chen still didn't let Zhou Yue and the others stop, and continued to dig.

Three hours later, the diameter of the bottom of the crater had become 100 meters, but the edge of the boulder was still not visible.

Luo Chen asked Zhou Yue and the others to stop.

How big is the diameter of 100 meters, the playground of the general elementary school may not be so big, but this boulder is far more than this size.

Luo Chen felt that even if he continued to dig, there would be no end to it.

He asked Zhou Yue and the others to clean up all the sand and gravel at the bottom of the pit with palm wind, and then he slowly fell.

Smooth and flat, within a hundred meters, there is not a single crack, there is no unevenness.

This boulder is definitely not a natural formation, but a man-made one.

Luo Chen quickly came to this conclusion.

However, this conclusion feels a bit nonsense, because the chain itself is buried in the ground by man, so it is not unusual for the boulder to be man-made.

But......

According to Luo Chen's estimate, there is more than one such boulder.

If his judgment was correct, all the bound beasts they encountered along the way were boulders like this.

At first, they thought it was the work of some super strong person, but now it seems that such a huge project is definitely not something that can be completed by one person.

So who is it? alien or indigenous?

Luo Chen felt that his brain was about to explode, there were too many mysteries, but he couldn't find any clues.

"Luo Shengzi, what should we do now?Do you continue to dig?" Zhou Yue saw that Luo Chen was silent for a while, and couldn't help but ask.

"Dig, but don't dig a hole. Luo Chen pointed to the iron chain buried deep in the boulder in the center of the big pit and said, "You dig down this iron chain and dig through this boulder, I want to see how deep this boulder is." ”

"Okay!" Zhou Yue and the others responded, immediately took out their weapons and began to dig.

Although the boulder was hard, it could not stop the sharpness of everyone's weapons, and a large pit was soon dug out.

However, the depth of this boulder is far beyond everyone's expectations.

They dug for more than ten meters, but they couldn't see the bottom.

However, Zhou Yue and the others did not pause for a moment, and continued to dig.

What Luo Chen said was to dig up the boulders.

Fifteen meters.

Twenty meters.

Thirty meters.

The pit in the boulder grew bigger and deeper, and the huge iron chain was revealed.

At this time, the length of the entire iron chain was more than sixty meters.

Judging from the material of this chain, the value of this 60-meter length is absolutely amazing.

There is also this boulder, which is more than 100 meters long and wide, and has a depth of more than 30 meters.

Such a boulder and an iron chain of astonishing value, just to tie up a ferocious beast, would be overkill.

"Boom!"

Suddenly, there was a metallic pop from the bottom of the crater.

Luo Chen's figure flashed, and he immediately rushed over.

At a depth of thirty-five meters, the boulder was finally dug through, but at the bottom of the boulder was a black, unknown metal plate.

The sound just now was the sound of Zhou Yue's sword slashing on the metal plate.

And most importantly, the chain passed through the boulder and then sank deep into the metal plate.

In other words, they haven't bottomed out yet.

"Are you still digging?" Zhou Yue looked at Luo Chen.

His sword is a fourth-order rune treasure, and he cut it just now, but there is no trace left on this metal plate, which shows that the hardness of this metal is very unusual, if you want to dig it, it is estimated that it will not be so easy.

"Don't dig the metal plate, keep digging the boulder and see if the iron plate is big. Luo Chen suspected that the metal plate might have been placed underneath to ensure that the iron chain did not loosen, and if that was the case, then the metal plate should not be too big.

"Good. Zhou Yue Dunn immediately took action.

But half an hour later, the group stopped, and then looked at Luo Chen with a wry smile on their faces.

The large pit on the boulder was more than ten meters in diameter, but the metal plate did not see the edge.

Obviously, the size of this metal plate is not smaller than this boulder.

And at this very moment.

"What do you think this is?" asked the purple wind chime, pointing to a small line on the metal plate.

Hearing this, everyone immediately looked over, and then followed, and everyone found that there were many such lines on this metal plate. It's just that they had been digging boulders before, so they didn't find it.

Hearing the movement, Luo Chen's figure flashed and also landed on the metal plate.

"Runes!" The moment he saw those lines, Luo Chen couldn't help but let out an exclamation.

"Is this a rune?" Purple Wind Chime frowned a little puzzled, "It seems to be different from what we usually see!"

"Well, it's different, but it's also a rune, but it's a different rune system, or to put it another way, it's the earliest rune. ”

Luo Chen explained: "The appearance of anything will have a process of evolution, and the same is true for runes, the runes we see now are extremely mature rune systems that have evolved for countless years, and on this metal plate are runes that were not sound in the early days. ”

"If my judgment is correct, these runes have existed for at least more than 10,000 years. ”

Hearing this, Zi Feng Chime and the others all nodded as if they didn't understand, they didn't know much about runes.

In fact, Luo Chen didn't know either, he could know because he happened to have this information in his head.

"And what is the purpose of this rune?" asked the purple wind chime a crucial question.

"It should be used to reinforce this metal plate, you get out of the way first, I'll see if I can crack it. Luo Chen said, walked over to the runes and squatted down, and studied them carefully.

After a few moments, he stood up, his hands fluttering, and he snapped out a series of runes.

When the runes are released, they fall into the runes on the metal plate, which then glows with white light.

The light flickered for a moment and then slowly disappeared, but there was no reaction on the metal plate.

"It's useless, how can it be useless?" Luo Chen's brows furrowed.

"Click!"

At this moment, a soft sound suddenly came out......
