Xiao Bai shrugged his shoulders and said, "This is obviously impossible, the leylines will keep moving to find a more suitable place for themselves, and if they are not artificially stopped, they will eventually form a natural wonder or treasure land in a short period of ten thousand years or tens of millions of years." ”

"These treasures have a fixed function, and in ancient times, they still had some strategic significance, and several major races would rank each treasure land and constantly fight for it, and even did not hesitate to blow up the entire planet in order to prevent the other party from getting it... But as we unify the entire galaxy and open up more unknowns, the value of these treasures gradually becomes less than the leyline. ”

"After all, the leyline's ability to transform resources in the process of becoming a treasure land is what we value."

"When the level of our entire race is improved, it will be difficult for ordinary people to be promoted in most of the treasure lands, and only a few of them will have higher output value and research significance than the leylines, and most of them will become amusement parks."

"But the leylines are not inexhaustible, I remember that in the time I lived there were very few leylines left, and after that, there was probably some new breakthrough in technology, but what exactly... I don't remember. ”

Hearing this description, Leng Xiyue roughly understood, like the eyes of ice and fire... In other words, the entire valley of Dugu Bo may have evolved from a single leyline.

The grade of the eyes of ice and fire is already considered to be the top in Douluo, and it will be of great help to the soul master of the ice or fire system even if he is titled Douluo, but it is just wasted by Dugu Bo, but if it is for the star spirit group at least above the god level per capita, this can only be used as a hot spring to soak.

"The leylines here have disappeared for tens of thousands of years, otherwise the cold marrow level here can be more refined, I speculate that this is probably just the momentum that the leylines have stayed here for a few months or a few years and leaked out of this cave to swim in this cave, which is the generation of this mine full of ten thousand years of cold marrow." Xiao Bai looked thoughtfully deeper into the cave, "But it can make the leylines stay, there are obviously some places in this place that we don't know, we may be able to explore deeper." ”

"Okay, Tianmeng hasn't woken up yet, let's go?" Leng Xiyue was also eager to try this.

As soon as they said go, the two of them did not stop at all, and walked directly towards the deeper part of the cave.

The cave was so large that the two of them had to fumble for a long time to find another path that led underground.

After walking along the trail for more than ten minutes, the vision in front of me suddenly opened up, and I saw an underground river flowing quietly from nowhere.

Although it was underground in this extreme north, Leng Xiyue did not feel the cold air it should have, but felt a warm and familiar atmosphere from it.

This underground river shimmered with a faint light, and it looked quite extraordinary, but in fact it was not a treasure, it was like a water resource mixed with some soul power, which was of little help to Leng Xiyue.

It seemed to be a tributary of the Yangtze River, flowing out of a large hole, and at the end of this underground river was a narrow passage that could barely allow her little Lori to pass, and behind the passage was a curtain of water, which looked like the cave was behind a waterfall.

Leng Xiyue glanced down through the waterfall, and saw that there were many soul beasts drinking in the lake below, even in groups, which looked very lively, and there were no soul beasts fighting here.

Perhaps the water flowing from here and the waterfall converged and subtly changed the water quality here, which is why the cold and lonely Far North has become such a lively place.

"Something is wrong, why is the road so smooth here?"

After wandering around for a while, Xiaobai soon discovered something strange.

"yes, the ground seems to be a little too flat, as if it was built by man." Leng Xiyue stomped her feet, and felt a little strange, the ground here was flat as if it was going to carry something through, this specification is not an ordinary highway, even the airport runway may not have this level.

It is difficult to attribute this level to a natural phenomenon, and such a smooth road is definitely not something that can be washed away by these rivers for thousands of years, it must have been something that someone did here a long time ago.

Walking up the underground river, the two of them soon reached the end. A stone gate appeared in front of them, and the water of the underground river poured down from the two holes next to the gate, and then Leng Xiyue realized that the underground river had also been dug in advance, and the water fell directly into the dug river channel and flowed towards the waterfall.

Before it fell into the river, the water was just an ordinary water resource, and there was nothing special about it except for the cool spots.

Leng Xiyue and Xiaobai took a closer look at the stone gate, which had many complicated lines, as if it was some kind of formation, there were a total of nine empty seats on it, and eight slightly smaller empty seats corresponded to the eight directions, and from the depression, it could be seen that they corresponded to eight kinds of items, namely a branch, a sword, a hammer, the horn of an unknown creature, a ring, a stone of unknown kind, a spear, and a very small groove that seemed to only hold a certain liquid.

In the middle is a strange sigil that seems to be used to place the key itself.

Leng Xiyue didn't have the slightest clue about these eight things, only the hammer was easy to associate with the Haotian Hammer, but she had seen the appearance of the Haotian Hammer in the book, and it was much different from this.

As for the sword and spear, they all look very ordinary, nothing special, let alone other things, and everything is probably no different from looking for a needle in a haystack.

Leng Xiyue speculated that this was an existence similar to the Doudi Cave Mansion that required many fragments to activate, as an ancient ruin, it was definitely not something that could be opened with brute force casually, even if it was useless to gather a few Titled Douluo.

She tried to attack twice, but the stone door did not move, so she summoned Caldalis out again and tried it, and it turned out to be as she expected, even Caldalys's full force did not leave the slightest trace.

"Xiaobai, do you have a way?" Caldalis couldn't open it, and Leng Xiyue had no idea, so he could only look at Xiaobai on the side.

"Yes." Xiaobai shrugged: "Let's collect all the things we need here, and this door will naturally open~"

This is the same as not saying it, Leng Xiyue simply gave up, and used the photo soul guide to take pictures of the appearance of each vacant seat here, and can only see if he can find some clues in the process of traveling or returning to the Wuhun Hall in the future.

"How did you get here?" Just as the two were about to go back, a voice came from behind them.

"Heavenly Dream? Are you awake? Come on, you've lived here for so long, you must know something about this place, right? Leng Xiyue said expectantly.

"Uh..." Tianmeng looked back at the narrow cave that could only accommodate one person to advance, and thought about his fat body again, and suddenly felt that Leng Xiyue's problem was a little bit wrong.

Looking at Leng Xiyue's expectant eyes, Tianmeng coughed dryly twice, and said with a little weakness: "I have scanned this place with spiritual power before, but this stone also has the effect of isolating spiritual power, and I can't penetrate it at all, but this is probably a seal set by a god-level powerhouse in that ancient era when there were many gods, and there may be some amazing monster sealed inside..."

"It could be some earth-shattering treasure, wouldn't it?" Leng Xiyue smiled slightly, looking at the seal with a little more eagerness.
