Su Chen felt that this rumbling sound seemed to have an inexplicable sense of familiarity, but he couldn't think of where he had heard it for a while. He hesitated, then looked around for a while, still not finding the source of the sound.

However, this look made him realize that in the direction of the big funnel, there seemed to be something small shining in a pile of gravel.

Su Chen jumped down from the lazy yellow crane, collected the sleeping beast in his arms into the chaotic space, let her return to the grass of the space to sleep peacefully, and ran towards the string of things that shimmered with a beautiful luster in the distance.

The surrounding lungs "saw" Su Chen, and they all began to pretend to be quails motionless in place, and Su Chen was not in the mood to pay attention to them, at the speed of Bolt, the wind swept past them.

Ran to the gravel, and the glittering thing seemed to be gone.

Su Chen simply squatted on the gravel, flipped and stirred in the gravel with his fingers, and searched carefully. He had just seen a bright flash. Even if it's not a treasure or something, it could be an important clue.

Su Chen rummaged for a while, and suddenly found a piece of white shell.

The ground here is covered with gravel, but there is no coast in sight, so where do the shells come from?

Su Chen paused for a moment, and then continued to rummage through the sand.

Immediately afterward, he spotted a small starfish that had been killed, probably the size of the palm of his hand, but judging by its color and shape, it probably hadn't been killed for long......

Su Chen remembered that the starfish seemed to die after dozens of minutes out of the water.

If the tide is low, starfish left on the beach will find damp and shady places to hide, and if they don't succeed, they can easily get dried in the sun......

Is this place very close to the sea?

Su Chen carefully recalled the route of the expedition, and clearly remembered that he first followed the large army that had received the integral task to explore the clues of the mysterious disappearance of the personnel and materials stationed in the eighth district, and came to the Yasugu Mountain Range. Then it entered the sandstone basin of the 8th District station with strong winds. Then, the senior sister opened the magic circle, and she and the senior sister entered the underground. The production line was discovered, and the nest of the Soul Eater was explored, and it was discovered that this ruin may be closely related to the Kututro people.

Subsequently, following in the footsteps of the Soul Eater, he saw a beautiful waterfall on the edge of a cliff, and he parted ways with his senior sister, and he even jumped off the cliff. After passing through a tunnel, the bones of the missing were found, and then he rode the Yellow Crane and flew to the current place, discovering the connection between the bones, the Soul Eater, and the Earth's lungs.

Su Chen summed up for a while, and tragically found that he seemed to be lost.

I don't know where this is, and I don't know if I can get back to the station of the 14th arrondissement.

However, judging by the shells and dried starfish and small crabs on the gravel, this place is probably not suitable for a long stay. Although it is not yet submerged in the sea, and I don't see any seawater myself, it is clearly not too far from the coastline.

Otherwise, there would be no trace of these weak sea creatures on the gravel here.

But what is it that sparkles from afar, but disappears up close? Su Chen couldn't let go of the doubts in his heart, so he simply turned to Huang He for help, climbed on Huang He's back, and let Huang He fly up to find it.

Although the arrogant Yellow Crane was a little impatient, it was rare that at this moment, his attitude was not bad, and he silently carried Su Chen on his back, and was still hovering at a low altitude more than one meter above the ground, so that Su Chen could observe at will.

Su Chen finally saw a few rays of light again.

Su Chen remembered the direction, ran over upside down, dug up all the sand and gravel in that area, and searched carefully almost inch by inch, in the process, his eyes were sour and unbearable, but he still didn't dare to blink, for fear that he would ignore the shining things if he was not careful.

Huang He couldn't help but shake his head and roll his eyes lazily as he watched Su Chen fall on all fours regardless of his image. Although this stinky boy always can't grasp the point, his eyes are very good!

Su Chen didn't have the ability to read minds, and he didn't hear Huang He's secret complaints, but even if he heard it, he could probably only laugh and laugh. There is no way, it is purely self-inflicted humiliation to compete with it in front of Huang He.

What's more, Su Chen's efforts were not in vain, he rummaged through and finally found something that shouldn't be here at all. Su Chen's entire mind was already deeply attracted by this thing.

It was a colorless, transparent crystal ball about the size of a hemp ball.

And, interestingly, inside this crystal ball, there is a very beautiful, breathtaking kernel.

It looks like a city full of people. The city is built on the foundation of a huge divine beast, and the buildings, landscapes, characters, and even their expressions and manners on the city are all lifelike.

Interestingly, the divine beast that supported the entire city was the rhinoceros dragon armor beast that had pulled the car for Su Chen before. It's just that it seems that the varieties are different, and the rhinoceros dragon armor beast in the crystal ball can even be used as a foundation to easily take on an entire city, which is obviously not ordinary.

The meticulousness of this carving reminded Su Chen of the miniature carving technique he had seen a long time ago. For example, there are mountains and rivers carved on the peach pit, there are pavilions and pavilions, and there is a flat boat scenery, and many facial details are carved on a grain of rice, and the folds of clothes are lifelike, and the characters are impeccable......

Speaking of which, this crystal ball, especially the city embedded in it, really doesn't look like a work of art made by a craftsman. On the contrary, it is more like this city used to be real, but at a certain moment, for some reason, a certain power, with this crystal ball, completely took them in, and has been frozen in that vivid moment.

The one that just emitted that kind of glitter is this crystal ball.

If it weren't for the fact that the top of the crystal ball suddenly reflected a few rays of sunlight, making it dazzling in an instant, Su Chen wouldn't even notice it, let alone be able to dig it out of this pile of sand.

It looks brand new and brand new, as if it has never been through the weather.

However, it should have been buried in the sand for a long time. It seems that this crystal ball itself may be a magic weapon. At least, Su Chen could feel the faint spiritual power fluctuations on its body. Well, the fluctuating rhythm is very different from the magic weapons or materials that Su Chen has come into contact with before.

Perhaps, it also has something to do with the civilization of the Kututro people.

The carved image inside this crystal ball may be the scene of the life of the Kututro people back then.

Perhaps, in this city, those bustling and disturbing people, all with vivid expressions, are reproducing the daily life of the Kututro people in those days.

The loud rumbling sound suddenly reverberated again, and Su Chen summoned the yellow crane, ready to fly up to see what was going on. Not long after he climbed onto the back of the yellow crane, Su Chen saw that on the side of the horizon, in the sky, in the distance, there was a high white wall, which seemed to be rapidly approaching his direction.
