I have to say.

The timeline that Gu Changsheng crossed this time seemed to be rather awkward.

If it was before the war broke out, Gu Changsheng might still be able to obtain information by communicating with the giants. And if it coincides with the time period when the conflict is taking place......

He can also get some more intuitive intelligence content.

This could be the intruder's appearance, abilities, or other more specific information.

After all, the invaders who can completely annihilate the giants must also symbolize some kind of power. If it is possible to observe it in its entirety and record it.

Judging from the resources that Gu Changsheng was sitting on, it was only a matter of time before he figured out where the other party came from.

At this point in his thoughts, he had to bring back the thoughts that had been sent out. He looked at the ruins in front of him, and at this moment he could only sigh softly.

Since it was too late, it could only accept fate.

Putting these corpses aside for the time being, Gu Changsheng continued to walk slowly in the direction of the hinterland. And the closer you get to the center, the more tragic the remains of these giants become.

Gu Changsheng even saw some remnants of organs that resembled limbs, torsos, or heads...... These things seemed to have been torn alive, and in the traces of charcoal, there was a subtle and cruel aura.

Gu Changsheng looked at it all in his eyes and secretly remembered it in his heart. He walked for half a pillar of incense again, and finally ......

In front of a high terrain, Gu Changsheng stood still.

He saw something in the shape of an altar, now placed on the highest place—and now it was flat except for this place.

This seems to be the central hinterland of the entire dungeon.

'Everything else has been charred, but only here still retains a certain peculiarity......

If Gu Changsheng didn't guess wrong, the intruder should have come for this thing?

With a little apprehension, Gu Changsheng raised his legs forward and walked straight towards the altar above.

It's closer.

Only then did Gu Changsheng see clearly what was placed on it.

It was a stone platform more than three meters wide and long, and under the solid material, there was now an arc-shaped pit showing in it.

Other than that, I can't find anything else right now.

Gu Changshengzi took a closer look at this stone-built high platform, and found that he could not find any other characteristics except for his unusual sturdiness.

This thing may also have to be made of some kind of special stone......

Gu Changsheng, who was not proficient in materials, did not dwell on it for too long, and seeing that there was no gain for the time being, he had to turn his gaze and then look in the direction of the pit.

It's not hard to see that there should have been something here.

Gu Changsheng tried to make a comparison, and realized that this should be something about one meter long and wide—now that it was empty, it meant that the intruder had succeeded.

But then again...... What has to be such a high bar that it can be placed in the center of a dungeon like this?

Thinking of this, Gu Changsheng also felt a little curious in his heart.

But as he said before.

This place is already the end of the fireworks after the fireworks, even if the residue on the ground is removed, Gu Changsheng still can't get a glimpse of its original appearance.

It seems that this is the only thing that can be found in the dungeon......

Just when Gu Changsheng's mind moved slightly, he was about to leave. The corner of his eye caught something unusual, which forced him to stop and pause slightly.

Wait a minute......

Something isn't quite right.

Gu Changsheng turned around suddenly, and at this moment, he walked straight towards the stone platform.

He lay down on the top of the table, and now he stretched out his hand and groped in the pit for a while. And when Gu Changsheng came back......

At his fingertips, there are now subtle marks.

Gu Changsheng brought it in front of him, and with the light above his head, he carefully looked at it for a moment.

It was like gravel, something extremely delicate and fine.

Now that Gu Changsheng rubbed it in his palm, he brought it under his nose, and looked at it carefully.

It is as fine as sand, but hard as iron. The touch is quite hard when you feel it, but if you rub it gently without using force, you can feel that the thing tends to soften.

Like gold but not gold, like iron but not iron.

Now, under the turquoise glow, these gritty things also radiate like new leaves.

Strange green material......

What has to be this?

Gu Changsheng's brows furrowed slightly, he thought about it for a moment, and then he seemed to remember something, and he couldn't help but shout.

"I remember!"

This thing is the same as the 'gravel' in the round table!

Yes, this thing feels good, hardness, and looks exactly the same as the things that covered me at the beginning.

It's just that......

Something different in color?

At this point, Gu Changsheng was stunned to see the sand in his hand, which was now changing color slightly.

The turquoise silhouette recedes like a tide, and finally reflects a rustic sheen like ore - will this thing change color?

As soon as his thoughts took shape, Gu Changsheng saw that these things began to turn into turquoise again.

Gu Changsheng's reaction was not slow, he immediately adjusted his posture, trying to cover the light source above his head......

I saw that the sand and gravel suddenly returned to its original color.

"You're affected by the light, which in turn reflects a different glow?"

After realizing this, Gu Changsheng's expression began to become richer.

There was a lot of confusion in his mind, not only because of the nature of the sand, but also because of ......

Why is this thing here again?!

You know, what is the Round Table Hall?

The ten benches placed there, as well as the brass door, are now the most mysterious venues in Gu Changsheng's opinion.

And these 'gravel' that appeared in the round table hall, as a reference content at the moment, there is no doubt that this thing is definitely not ordinary!

Gu Changsheng's thoughts were flying now, and his whole body was lying directly on the stone platform. Gu Changsheng looked inside for a while, and finally groped for a small handful of gravel.

Looking at this strange thing in his hand, Gu Changsheng sat cross-legged on the stone platform, and couldn't help but show a thoughtful expression.

Since this thing can appear in such an important place, it must have an extremely unique effect.

Let's say this is the center of the dungeon, and it's also the target of the invaders. That......

What is the connection between the sand and the looted thing?

The thoughts in Gu Changsheng's mind rose and fell, but a sudden thought came to him at the end.

There is no one possibility.

Is this so-called sand and gravel something coming off something?

It's like...... Originally, there was an object embedded in the stone platform.

It is pried, it is carried.

There may also be some wear and tear along the way, which later causes some of it to fall off and eventually become debris scattered in the stone platform.

Gu Changsheng's gaze straightened slightly, and at this moment, he also had a more appropriate conclusion in his heart.

That's right, that's right......

Assuming that the target of the invaders is this stone platform, then all this strangeness can be explained clearly. And for now, the only remaining confusion remains.

That's what the whole of the sand is.

Gu Changsheng raised the small things in his hand flatly, facing the flickering and immortal Milky Way above his head, and the brilliance in his eyes was also swallowed at this moment.

"You...... What exactly is the origin? ”

No one answered, no one responded.

With such a curious thought, Gu Changsheng had no choice but to rearrange his way on the road at this moment. He moved away from the stone platform and briefly compared the direction he had come......

It's about moving in a completely different direction.

After all, it seems that the dungeon has been abandoned for now. If he couldn't take this opportunity to take a closer look, he Gu Changsheng would have come for nothing.

Between the starry sky underground, Gu Changsheng was like a mouse that had broken into a labyrinth. He went in and out, back and forth, and dangled for a while.

Finally I was able to regain my footing.

After reading it all, there should be nothing left - with such thoughts in his heart, Gu Changsheng couldn't help but sigh lightly.

There is no extra gain......

Except for the charred corpses that fell to the ground, Gu Changsheng could no longer see any other signs of 'life'.

It seems that he did come too late.

Whether it is useful information or information that can be referred to, it has been taken away at this moment, or it has been lost in the long river of time.

Thinking of this, Gu Changsheng even regretted it a little...... After all, the two stuffed monsters he had seen in the sewers before were the only living creatures he could meet on this trip.

"Forget it, don't think about it......"

It was useless to regret what had passed, Gu Changsheng regained his spirits, and at this moment he chose to lean towards the edge of the dungeon.

After half a circle, Gu Changsheng found the place where he had marked before. I saw that he came to the mouth of the sewer, and he stopped slightly.

Gu Changsheng took one last look at the uninhabited dungeon behind him, and then jumped into the pit and jumped straight into the hole.

Under this vast 'starry sky', the few remaining vitality dissipated again at this moment.

The remnants of the charcoal fell asleep again, and began to wait for the baptism of time again......

- It was supposed to be so.

In a corner that Gu Changsheng couldn't perceive, the most central area of the entire dungeon.

The rough stone platform, which seemed to be immutable for eternity, began to tremble slightly at this moment. It seems that it is because of the sand and gravel that Gu Changsheng took away, and it seems that it has touched some kind of limit......

But there was an abrupt whisper, and a moment later, cracks as thin as hemp stalks had already climbed to the stone platform.

The cracks were vertical and vertical up and down, and they were connected into strips. If someone were to look at it at the moment, they would see that the crack had almost halved the entire stone platform.

Gurgle, cluck......

A small, yet heart-wrenching echo reverberated at this moment. Like a beast that is about to die, the mournful roar emitted by the stone platform is incessant, and the sound is endless.

The crack began to spread, to bloom. Like a blooming flower, there is a suffocating sense of crisis between the verge of collapse.

If Gu Changsheng was standing beside him, he would clearly feel it at this moment......

Something, is crumbling.

There's also something that's on the move.

There was an explosion on the ground, and the stone platform cracked at this moment, turning into pieces dancing wildly! And as the stone platform splashed, the pedestal under it also collapsed at the same time.

And this tendency to collapse is like a virus that is spreading, and with a visible trend, the surrounding ground, corpses, and even the air began to tremble violently at this moment!

It was as if it were a that had been drilled out of a hole, and out of that insignificant crack was born a surging wave that could break everything.

At this moment, this whole dungeon ......

The process of disillusionment began.

……

There is a way to be cautious when you come and hasty when you go. Because Gu Changsheng had already figured out the way he came from earlier, he was now turning back again, and the speed was different from before.

He walked briskly, hurrying through the hole. On the way, Gu Changsheng also stopped from time to time to rest for a while, so that his state could be adjusted.

After all, no one can guarantee that those two stuffed monsters will not crouch on the road to guard him.

Gu Changsheng has always firmly believed in the view that 'there is no big mistake in being careful', and he will not relax his muscles at such a critical juncture.

And so on all the way stop-and-go, and soon ...... Gu Changsheng saw the 'pit' when he came.

Found the starting point.

This shows that the place where the 'stone wall' was originally placed is now not far away.

Gu Changsheng's heart was slightly cold, and he was also careful at this moment. And just when he wanted to move on, behind him, there was a sudden violent roar.

It was as if something had exploded suddenly, and the sound rolled into a huge wave, turning into a violent wind, and at that moment it poured straight into the sewers.

Gu Changsheng was caught off guard, and even stumbled for a while. Thankfully, he's in a good fit and hasn't been able to fall top-heavy now – he quickly regained his fitness and was able to get back on his feet.

Why did such a violent explosion suddenly occur behind it?

Gu Changsheng couldn't quite understand it for the time being, he had just stood firm for a moment now, and then he was pushed to the ground by the sound that followed.

The continuous roar came like a tide, making Gu Changsheng's face a little ugly.

Something is very wrong.

Such an exaggerated degree makes no sense......

Unless there's a problem with the dungeon!

As if confirming Gu Changsheng's thoughts, the entire sewer began to tremble. The fine stone residue slipped from the top and fell in front of him, making Gu Changsheng also realize the seriousness of the problem.

Don't go again......

I'm afraid I'm going to be buried alive here!
