It didn't take long for Guan Yun to have five more gray-blue demonic fragments in his hand, these demonic fragments were much more than those bones, and they were the same as the demonic fragments that Guan Yun had obtained before, with gray impurities.

"These demonic fragments are likely to have something to do with cultivation, the higher the cultivation, the purer the demonic fragments. Guan Yun carefully looked at the five spars in his hand and thought for a while.

Guan Yun still remembered that the demonic fragments he had obtained before were collected by Gao Xiang from the Northeast Fortress for him, and there were also a lot of impurities, and the quality was not even as high as these beast bones.

Guan Yun originally thought that only demonic beasts would produce demonic fragments with impurities, but the Northeast Fortress faced the demon army, and the demonic fragments were also obtained by killing the demon army, which made him suspect that the purity of the demonic fragments was probably related to cultivation.

"The leader of this demon clan must have cultivated very high during his lifetime, but why did he die in this place. Guan Yun took a closer look at the bones, the weapons were all broken, and there were obvious fractures on the bones, obviously after a fierce battle.

After listening to Guan Yun's words, Zhou Liang also lowered his head and thought carefully: "Could it be that the strong men of the human race discovered them and killed them?"

"If the strong man of the human race is very likely, it's just that since the strong man of the human race discovered the plan of this demon race, why didn't he report it, but let them continue to be able to sneak over and sneak into the Great Forest of Hoshino?"

"And after the Terran powerhouse killed these demons, why did they move their corpses to this hidden cave, and the demon fragments of such a high quality were not taken away, but left in the corpses. ”

The other three also glanced at each other, a little dazed, if it was really done by the strong man of the human race, there was no need to hide the demon corpse in this cave, and these high-quality demonic fragments were necessary materials for building high-level weapons, there was no reason not to take them.

Zhang Xiaolong glanced at Guan Yun and asked with some confusion: "You mean, it wasn't done by the strong people of the human race?"

"I'm not sure yet, I just don't understand the meaning of the Terran powerhouse doing this, but we can think differently, if these are not done by the Terran powerhouse, who is most likely to do it. Guan Yun's eyes were fixed and he looked at the other people.

Zhang Xiaolong saw Guan Yun's eyes, and instantly understood what he meant, and nodded slightly: "If it wasn't done by the strong man of the human race, then it is most likely the strong man of the sea clan!!

"Sea Clan?!!" Zhou Liang and Guan Lei were a little surprised, and looked at Zhang Xiaolong and Guan Yun.

"That's right, this is far away from the near shore, of course it is normal to have the presence of the Sea Clan, and the Sea Clan does not need demonic fragments, and in the primeval period, the Demon Clan invaded, although it did not infect the territory of the Sea Clan, but the Sea Clan still has a natural hostility towards the Demon Clan, so it is not impossible to make a move. ”

Zhang Xiaolong has followed Zhang Sheng to the deep sea, and has seen many powerful sea clans, even Zhang Sheng is extremely impressed by the powerful strength of the sea clan, and it is normal for the demon clan, as an extraterritorial evil race, to be hostile to the races in this region.

"And the sea clan is extremely sensitive to the breath of the demons, and they will not throw the corpses of the demons into the ocean where they live, so it is not impossible to throw them on this desert island. ”

Guan Yun's eyes flashed slightly after hearing this, and then Zhang Xiaolong's words continued: "If this is the case, then it also explains why the demon clan did not report it after discovering it, but gave other demons a chance to sneak into the Hoshino Great Forest, it is likely that the strong man of the sea clan accidentally found the smuggled demon clan, killed it, and then left, did not continue to stay here and wait for the demon clan." ”

"Could it really be the ?!! done by the Sea Clan" Zhou Liang also understood Liang Rao's explanation, and glanced at the skeletons again, these demons were really unlucky, touching the strong people of the Sea Clan.

Several people continued to search to see if these demons left any valuable clues, but they found nothing, except for the corpses, there was no other useful information.

"These corpses are of no value, let's hurry up and see if there is anything special about this desert island, don't forget that our purpose is to investigate the frenzy of fish. Guan Lei paused, picked up the torch on the side, and reminded the other three.

"Let's go, let's go inside the cave. Hearing Guan Lei's words, Guan Yun also withdrew his gaze from these bones, they still had to solve the frenzy of fish on this trip.

Zhou Liang and Zhang Xiaolong did not continue to stay here, picked up torches and followed the footsteps of Guan Lei and Guan Yun, and stretched out towards the cave.

Although the entrance of this cave is not big, but the cave is indeed very large and deep, Guan Yun suspects that the inside of this mountain is hollow, they walked in it for dozens of feet, and still did not see the bottom of the cave, but the further inward, the narrower the cave became, and the cave actually had a downward angle.

"This cave is so deep, why hasn't it reached the end yet. The further they went, the dimmer the light became, and several people could clearly feel the path beneath their feet, beginning to slowly lead diagonally downward.

"We seem to be going down. Guan Yun frowned, because the angle of this cave was getting steeper and steeper, but the road around it was getting smoother and smoother.

"Oh no, this mountain seems to be hollow, and this cave seems to lead to the bottom of the mountain. Guan Lei, who was walking in the front, stopped, because he found that the road in front of him was almost vertical, and he could not go down at all.

The three Guan Yun who followed behind also saw that there was almost no way ahead, and Zhou Liang also poked his head down to look down, and it was dark and he couldn't see the bottom of the cave.

Guan Lei in front also poked his head and threw down the torch in his hand, only to see a firelight falling in the hole, until it became a point of light and disappeared into a few rays of vision.

"it!!It's so deep!!If you fall, you'll have to be crushed. Zhou Liang, who had been observing the fall of the torches, couldn't help but exclaim.

"Is this mountain so high?" Guan Yun looked at the torch, and it was four or five hundred zhang to fall, and the mountain they had climbed was only less than four hundred zhang, not to mention that they had already walked down some distance before.

"Daddy, is this still going down?" Guan Yun glanced at Guan Lei and asked.

"No, the cave is too deep, there is no such long rope, and we are here to investigate the fish, this cave is to stop by to investigate, and prepare to go back." Guan Lei shook his head, it was a little surprising to find the corpses of the demons in this cave, but the purpose of their trip was not to find these demons, since there was no way, they naturally had to go back the same way.
