Leng Xuan, on the other hand, began to wander back and forth on the flat ground, carefully observing every place. After repeated investigations, he couldn't help but move in his heart, as if he had found some pattern, but he couldn't grasp it for a while. After thinking for a moment, he suddenly clapped his hands and said, "Dragon's head, I think I know the truth." ”

Hearing this, the dragon head immediately became interested, and hurriedly asked, "What's the matter?" What did you find? ”

Leng Xuan stood next to those strange stone pillars on the flat ground and said, "Don't you think the location of these stone pillars is a little strange? If I'm not mistaken, their orientation should be arranged in the arrangement of the stars. However, there are a few stone pillars that are placed in the wrong place, which is why they look a little messy. ”

After observing for a while, the dragon head nodded and said, "You are right, there is indeed a kind of arrangement of stars in it." But, according to what you say, then this should be man-made, and it is too far-fetched to say that it is a coincidence alone. After pondering for a moment, he continued: "I remember that in ancient times, those cultivators used to use the stars as objects to arrange formations, which were called Star Arrays. However, later, because this formation was too easy to crack and coincided with the birth of the Bagua Array, it was gradually abandoned by the world. Speaking of which, the Star Array is still the first formation created by the cultivators, and it is also a good luck that we can see this formation now. ”

Leng Xuan hurriedly asked, "Dragon Head, since you know this formation, do you know how to crack the Dao?" ”

The dragon head shook his head and said: "I don't know the way to crack it, but it is not difficult to remove this formation, as long as you have an understanding of the arrangement of the stars, you can easily solve it." To be honest, this kind of star array is not to mention us, even if you find an ordinary person who has studied astronomy, you can do it. With that, he began to carefully observe the arrangement of the stone pillars, and then slowly moved some of the irregularly placed stone pillars to keep them in the correct position.

After more than ten minutes of busyness, the two finally completed the arrangement of the stone pillars. After doing all this, the two stepped aside, expecting in their hearts what would happen. After a while, I saw a sudden loosening on the stone wall that met the ground. A dazzling light spread across the stone wall, and then I saw that the stone wall had become soft and rippled like water.

The dragon head and Leng Xuan immediately rushed over, and when they came to the side of the stone wall, the dragon head stretched out his hand and reached out to the stone wall. However, when his hand touched the stone wall, it was immediately bounced away. Seeing this, the two couldn't help frowning. After pondering for a moment, the dragon head reached out again, and this time, his hand crossed the stone wall smoothly. His face was suddenly filled with excitement, and he said: "Protect your whole body with true qi, this stone wall repels the flesh and only accepts true qi to enter." ”

Leng Xuan hurriedly activated his true qi, protected his body, and then walked towards the stone wall with the dragon's head. After easily entering the stone wall, there was a long passage in front of the two of them, the stone walls on both sides were extremely smooth, and above the passage, a white bead that emitted light was hung every ten meters or so.

Not only that, but in this passage, the two of them felt an incomparably rich aura, which was even purer and more enormous than the heaven and earth aura they usually absorbed when they cultivated.
