In the middle of the Boundless Desert, thousands of meters from the surface of the sand, two monks, a man and a woman, were cautiously groping their way forward in a colorful mine.

"I used to think that the spirit stones were not enough, but now that there are so many spirit stones around me, I have no place to spend them, except for cultivating, they are useless! Now I am annoyed when I see these cold spirit stone mines! When can we leave this place?" A woman's complaint came from the mine.

"As long as we don't give up, we will definitely find a way out!" a male voice sounded, as if comforting the female nun beside him, and as if encouraging himself.

The mine cave is like a winding and circling dragon, constantly extending forward, Xia Wang and Mu Shuilan, who are walking in the cave, look at the endless ahead, their hearts are full of powerlessness, after they fell into the quicksand pit, they woke up and found that they were in this mine.

Seeing so many spirit stones at the beginning, Xia Wang and Mu Shuilan were very happy, especially Xia Wang, who had never had any spirit stones, when he first came in, he was almost digging spirit stones, and he didn't stop until his storage ring was filled.

After nearly two years of being in this cave, they have now turned a blind eye to the spirit stones around them, and even if the top-grade spirit stones that even the Avatar Cultivators treasure appear in the mine, it will not make them feel a little flustered in their hearts.

The scenery in the cave is even more strange, there are many five-colored spirit stones of different sizes hanging on the top of the cave, and there are obvious traces of excavation at the bottom of the cave, this spirit vein should have been discovered and mined a long time ago. I just don't know why I am abandoned in this endless desert now.

The structure of the mine itself is very peculiar, there are holes in the hole, Xia Wang and Mu Shuilan walk in the hole, often dizzy, the width and width are constantly changing in front of them with the footsteps of the two of them. The wide place can accommodate dozens of people, and the narrow place can only be passed by one person sideways.

"Hmph, it's all to blame on that damn Yuanying Monk, if it weren't for him, we wouldn't have been trapped here for so long!" Mu Shuilan gritted her teeth and said, "Don't let me see him in the future, otherwise I will make him look good!"

"Okay, when we go out, if we meet that Yuanying Monk, I will deal with him with you!" Xia Wang said approvingly, a Yuanying Monk used Xiu as a shield for a female cultivator lower than him in order to survive for himself, which made him feel ashamed!

"Then we've made up our minds, you can help me deal with him when we get out, if he's not dead!"

"Well, when the time comes, call Senior Sister and them, and we will definitely be able to beat that Yuanying Monk to the ground!"

"Hehe, Tianwang, this time it was for nothing, but I said why are you so stupid, you know that the quicksand pit will kill people, and you still jump with you!"

"Senior Sister Shui Lan, we are companions, how could I watch you being buried by quicksand alone!" Xia Wang replied without thinking.

"Thank you, if I had been here alone for so long, I think I would have gone crazy! Fortunately, I had you with me!" Listening to Xia Wang's words, Mu Shuilan was very moved in her heart, and a deep smile appeared in her eyes.

When she was pulled into the quicksand by the Yuanying monk, Mu Shuilan thought she was dead, but at the moment when the quicksand flooded her head, she saw Xia Wang rushing towards her without hesitation, she still remembered how shaken she was at that time, and an indescribable feeling immediately welled up in her heart, which is still entangled in her heart.

While Xia Wang and Mu Shuilan were constantly looking for a way out of the mine underground, Ning Xin took the little black bear and walked slowly in the desert above them.

After leaving the desert, where thunder and the sound of silk and bamboo orchestras were heard from time to time, Ning Xin took Xiao Hei and Xiao Xiong all the way towards the place where the mirage had appeared.

Although she knew that the mirage was just a natural phenomenon, she still regarded it as a guide from the desert to her, and at this time, Ning Xin obviously forgot that this was a world of cultivating immortals, and all natural phenomena could contain specific chances.

A few days later, a man, a bird, and a bear came to a place that was noticeably different from other deserts. Looking at the area of black and fine gravel everywhere in front of her, Ning Xin stopped.

Circles of gravel cover the surface of this area, the small inner diameter is about one meter, such gravel circles account for the majority, and the large inner diameter is hundreds of meters, in Ning Xin's divine consciousness, there are only a few.

From a distance, surrounded by golden grains of sand, it is like drawing a map of stars in the desert, the big ones like the moon and the small ones like the stars.

Ning Xin didn't venture into those gravel circles, she found that the arrangement of these gravel circles seemed to imply some kind of law, just like the dead trees with white bones buried in the Demon Dead Forest, which seemed to be chaotic, but in fact they were implicated in each other.

"Xiaobai, do you think there is anything wrong with these gravel circles?"

"I can't see it yet, if you want to know what's hidden inside, you guess you'll have to go in and take a look. ”

"Xiao Hei, do you see if there is anything else in front of you besides the gravel circle?" Ning Xin asked Xiao Hei again, she wasn't sure if there was a phantom array or something like that.

"Nothing, it's all a circle of black stones!"

"Since we've met, let's go in and have a look!"

After thinking about it, Ning Xin finally walked into this gravel circle area, but when she stood in it with her feet, she regretted it, and in an instant, she saw that the scene in her eyes immediately changed, and Ning Xin secretly exclaimed in her heart that these gravel circles were a big array.

Originally, she was still in the scorching sun of daylight a moment ago, but now she has transformed into a black night sky surrounded by countless starlight, and countless starlight in the sky are faintly or faintly flickering. It's like an infinite void space, and you can't poke your head out at all.

"Xiao Hei, what do you see now?" Ning Xin asked a little nervously.

"Master, why is it dark this day? There are so many stars!" called out Hei.

"It's not a phantom array!" Ning Xin said after hearing Xiao Hei say this.

"This is a bit like the Tiangang Star Array!" Xiao Bai said uncertainly.

"Tiangang Star Array, have you seen it?" Ning Xin asked.

"No, I've just heard of it, I think those monks who have seen this formation are probably dead! This is a very famous formation in ancient times, which integrates the killing array and trapping the formation, and the ancient Tiangang Sect's great array of protecting the sect! There was once a sect that looked at the spiritual veins of the Tiangang Sect and wanted to seize it, but as a result, the disciples of that sect were all trapped in this Tiangang Star Array, and no one survived!"

"So powerful!, can we still get out of this formation?"

"This star array should be missing, otherwise you should be attacked by the formation as soon as you come in! We may still get out! It depends on you, fortunately, your formation attainments are not bad, if a monk who doesn't understand the formation comes in, it is estimated that he will only be trapped to death!"

This Tiangang Star Array, Ning Xin had never heard of it before, Xiaobai, he knew the name of this formation, and he didn't know anything about how to break the formation, and now he could only rely on Ning Xin to explore it step by step.

Slowly, Ning Xin found that some of the starlight in the sky flickered very regularly, and the position corresponding to the brighter starlight was a bit similar to the direction of the gravel circles with an inner diameter of hundreds of meters that she noticed before, and the starlight distribution in the sky was related to the gravel circles she had seen before!

It's a pity that the area covered by this gravel circle is too wide, and with her current cultivation divine sense, she can only explore within a hundred miles, and she doesn't know the gravel circle branches in other areas at all.

After knowing that the gravel circle was related to the stars in the sky, Ning Xin deduced in this direction and walked into the depths of the gravel circle step by step.

As Ning Xin continued to move forward, suddenly a meteor-like starlight quickly pierced the night sky and attacked Ning Xin.

"Flash!" Xiao Bai shouted loudly in Ning Xin's mind.
