It's a vague connection, and Kasia thinks about it, but in the end he doesn't get anything. Sighing, he withdrew his hand and stood on the stone steps looking at the circular hole where the dark river came out, and there were still traces of the excavation. The network of caves that Grote refers to is not a natural formation, and there are many artificial components in it, like a place for some people to store something, or to hold something. Upon closer inspection, Kasia ruled out that this was the choice that the prospectors had concocted. Very particular, very delicate excavation methods, compared with the group of prospectors, if there is a place to stop them, directional blasting will be their first choice.

It now seemed to Kasia that Grote's choice to place the second-generation Holy Sword here was not a random move. I didn't think much about it before, but all the signs here show that when Grlot chose to place the second-generation holy sword, he had already guessed his future ending. And there is another place that makes Kasia even more confused, that is, when the agreement was reached in the spiritual dream, it can be said that one of the two conditions was not fulfilled.

In exchange for the second generation of the Holy Sword, there are two conditions, one is to protect the safety of Doris, a contemporary saint, who has gone to other continents, and the second is to let Kasia throw his skull into the endless sea. It was done, so to speak, but when he threw the skull into the endless sea, Kasia determined that Grote's spirit had disappeared from the skull.

But none of that mattered, and Kasia wondered something else—why he threw his skull into the endless sea. Grote was not from the coastal region and might have a longing for the sea, but as the first knight king of the empire, he lived for more than a hundred years, and Cassia did not believe that he had never seen the sea.

"Could it be something else?" Cassia was sure of this, but he couldn't think of what it might be.

In the past thousand years, except for some spaces or ruins hidden under the ground, or some special locations in extreme regions, the empire has explored all the post-phase continents that can be explored. However, the Endless Sea is the only special region that has been listed separately, and the other two continents are no exception.

"The Endless Sea has no bounds, and in the hundreds of years since the airships and giant cruise ships on the sea were perfected by Avalon, these steel giants who have conquered the offshore and deep blue skies have still not been able to explore the edge of the Endless Sea. In the course of his voyages, he discovered numerous island groups or small islands the size of a small country, but everyone knew that this was not what the explorers and empires wanted、、、 "In books about the Endless Sea, there is often such a sentence.

As an ocean that surrounds three continents, the area of the Endless Sea that has been explored has already exceeded the area of the three continents combined. As its name suggests, there really is no boundary, only islands exist, and at the same time, it also shows the infinite possibilities of existence and its depths.

It's just that after hundreds of years, even though there is no shortage of enthusiastic young explorers in every era, the expansion of exploration of the endless sea has become weaker and weaker. The farther away from the mainland, the more dangerous it becomes. At the height of the wave, an expedition led by the Empire set sail. At that time, the team had dozens of huge cruise ships, equipped with the same number of airships, plus all kinds of explorers who had been strictly screened, and even the imperial and military departments secretly helped behind the scenes, sending the elite of the army as military protection.

But in the end, it disappeared into the eternal dark blue skyline of the Endless Sea. It was then that the term Endless Sea truly took on meaning.

It represents not only the endless end, but also the mystery and the fear of the unknown that humanity has so far had, or it symbolizes power.

Kasia could only look sideways to find a reason for Grote to throw his skull into the endless sea. It is not possible to guess what Grote thinks, or if there is a serious lack of information. As the first generation of knight kings after the establishment of the empire, with his power and strength, Grote had access to much more secret knowledge than he did at that time.

Instead of spending any more time on it, Kasia looked at the mechanical watch, which was close to two o'clock in the afternoon, and it was still sufficient. He returned to the steps to pick up the firecracker, checked his condition and made sure he was in good shape, and walked to the hole where the dark river came out. As for the piles of diamonds and jewels in the dragon skulls, he thought he had plenty of time to move them away.

The cave is about a meter and a half in diameter, and Kasia can enter it with a slight bow. The dark river water is so fast that it can splash directly in his face.

It is not completely excavated by hand, it is a semi-natural cave, which has been carefully excavated. Less than two or three meters away, in the darkness that had been dispelled a little, Kasia found the bottom of the wedge embedded in the rock wall, which had been corroded by the rock. The group of prospectors prepared to walk in the rushing river.

Soon after, Kasia even found a broken waterproof light fixture. After a long distance, one or two hundred meters, you can still see the line fixed to the stone wall. But there seemed to be no end to the cave, and the river became more and more turbulent, and the only sound of the torrent in the silent and dark cave was constantly echoing in the ears.

After about a few hundred meters of diagonal upward progress, a spacious underground space appeared in front of him, seven or eight meters high, and the length was also about twenty or thirty meters. There are several caves of various sizes connected here, where the dark rivers converge to form a small pool of water with churning water in the lower areas.

Beside the water is a flat area of dry gravel, where there are a few collapsed tents. Luckily, I found unused solid fuel on the side, and the fire lit up the surroundings shortly after. The stone walls have been excavated by hand, and there are not only bizarre text symbols on them, but also several coherent sketches. And there are also obvious fixed-point blasting marks and knock marks from excavation.

The group of prospectors found something on the stone wall, and the creatures in the sketch were missing eyes, it must have been diamonds and jewels, Kasia judged. On his way here, he would occasionally see less obvious explosion craters in the cave walls. Perhaps it was these diamond jewels that drove the group through the long cave to explore here.

I don't understand the words on the stone wall, but Kassia can still understand some of the pictures. There are a total of six sketched stone paintings, the first of which should be a common starry sky, but there are many meteor-like things under the starry sky, as if the stars have fallen. The second one is indiscernible in its significance, it is six circles of different sizes, but by the starry spots on the side, Kasia judged that it should be the moon, but why there were six of them. Or is it something else?

The third is a huge whale breaking through the sea and leaping in mid-air. It's a whale, Kasia thought of it immediately.

The fourth one seemed to be a mountain, and when Kasia looked closely, he realized that it was not a mountain, but a tree that was far more majestic than the peak. Huge trees run through the heavens and the earth, and the mountains are only its foundations.

The fifth painting seems to be interconnected with the fourth. A man stands on the branch of a large tree, with long hair and exaggerated chest indicating that this is a woman. Holding a scepter in his hand, he glowed with dazzling light and looked at the sea of clouds churning in front of him. The woman in the stone painting is not an ordinary human, she has two sets of wings behind her, as light as the wings of an insect. Even though this is a sketch, it still reveals the beauty of the two pairs of wings.

The last one, on the other hand, is the creature that Cassia is most familiar with, a dragon. Although the eyes were missing, the fangs in his mouth and the flames splattered from his body could still feel terrifying. The dragon flew in the sky, its body obscuring the sun, and below, a group of kneeling men worshipped sincerely. In front of this group of people, there are also six shelves on which six women are hanging, all of them women with two pairs of wings, as depicted in the fourth painting!

"It's a sacrificial event!"

Kasia knows from some history books that in ancient times, people used this ritual to please their gods.
