Everyone set up an awning to avoid the scorching sun, and after the sun turned west, they hid in the back of the sand dunes and patiently survived the day.

Soon after the sun went down, a waning moon rose in the sky, and the stars began to appear in the sky.

Luo Luoshan took out his compass and stargazing scope to determine the bearing, and then set off with everyone. Every two or three miles, the mountain of Loro stopped for a rest, and after walking for three hours, the group of nine men finally returned to the place where they had buried their boat.

After only one day, the highest sand dune seemed to have become much shorter, and the wooden sticks planted in Loro Mountain were blown down by the wind and sand, but they were not completely buried, and the sand boats in the yellow sand were still there.

Climbing the small sand dunes, the stone forest two hundred zhang away is vividly visible under the starlight, and even the two stone pillars that collapsed yesterday are faintly recognizable.

"Great!" Bai Xu smiled, "We're finally back here again." ”

"That's right," said Loroshan, "let's camp in the leeward of the sand dunes and wait for dawn!" ”

At dawn, the wind struck again, this time much stronger than yesterday, and it took two hours before it slowly subsided.

Everyone came out of the tent half-buried in the yellow sand, looked up at the sky, and Luo Luoshan said, "The sun has risen two poles high. Let's hurry up and get inside. ”

The group climbed the sand dunes in front of them and looked in the direction of the stone forest, but they all looked at each other dumbfounded.

It turned out that the stone forest two hundred zhang away was gone, and there was now only a piece of reckless yellow sand in that direction.

"Your mother!" Luo Luoshan rubbed his eyes in disbelief and scolded in frustration, "This is too fucking unlucky, isn't it?" In just one night, this stone forest passage was filled in by this sandstorm? ”

Naturally, everyone was as disappointed as Luo Luo Mountain. Duan Wutian and Anan Adong scolded at God at the same time, and Luo Luoshan, Chen Tianye, Bai Sha Heisha and the others seemed to can't believe their eyes, and couldn't help but turn around to look around, lest they had made a mistake.

However, it is the same in all directions, and there is only reckless yellow sand as far as the eye can see.

"Alas!" Bai Sha looked around for a long time, and finally let out a long sigh and said, "It seems that the window period has disappeared, and we have to wait for the next time." Boss Luo, what do you say? ”

"What else can I say?" Luo Luoshan smiled bitterly, "Go back!" I don't know what year or month it will have to be! It's just one day away, and I'm really unwilling to ......"

The people were dejected and about to go back.

"Slow!" Qingshi suddenly said, "Don't rush to conclusions, be a little more patient and careful." ”

"Huh?"

Only then did everyone realize that Qingshi had been observing from all sides, but he had not made a sound.

"Brother Haiya!" "Did you notice something wrong?" ”

"Not yet," said Bluestone, "but don't forget it's daytime, and we'll be careful not to be fooled by the illusion of light and shadow again." ”

"Ugh!"

Everyone was stunned for a moment, and then suddenly came to their senses.

"That's right!" Bai Sha shouted, "What we see now is not necessarily the truth, maybe the stone forest is still there, and it has not been buried, but we can't see it." ”

"Yes, yes!" Luo Luoshan also came to his senses, "It makes sense, the more I think about it, the more I feel it makes sense!" I just said, how can you be so unlucky, it just so happened that today's sandstorm buried the stone forest passage? It's mostly a illusion, or the Haiya brothers are smart. ”

"I'm still the same," Aoshi said unhurriedly, "don't jump to conclusions. We were deceived by the illusion of light and shadow, or the stone forest passage was really buried by the yellow sand, both possibilities. ”

"In that case, that's easy!" Chen Tianye said, "Just give it a try and you'll know!" ”

"How do you try?" Bai Sha asked.

"Simple," Chen Tianye said, "let's divide into four teams, each team chooses a direction to advance two hundred zhang, and there will always be a team that will step into the stone forest, I mean if the stone forest is still there." ”

"There is some truth," Luo Luoshan said in thought, "If the Stone Forest is still there, it is possible to break through the illusion and find the Stone Forest, but this is a blind collision, and it is more likely that none of the teams will be able to hit it." ”

"Yes!" "Since the direction is chaotic, it is impossible for us to find out whether the four teams are all in the right direction in the first place. Secondly, the entrance of this stone forest is only a few dozen zhang wide, even if the stone forest is still there, the direction is correct, but the slightest mistake will miss the pool. ”

"Then try a few more times!" Chen Tianye said, "Anyway, I believe that the stone forest is still 100% still there, and we are definitely fascinated by the illusion." ”

"Why don't you ......," Luo Luoshan said thoughtfully, "Why don't we try, Brother Haiya, what do you say?" ”

"Can't try!" Qingshi was still carefully observing the surroundings, and said as he observed, "The chance of finding the stone forest by stumbling into this kind of chaos is too low, but the possibility of crashing into the quicksand river is very high." ”

"Ugh!"

Everyone woke up again and knew that this method did not work.

"What then?" Luo Luoshan asked, at this point, he had subconsciously given up his status as the backbone to Qingshi.

"Look closely!" Bluestone said, "Look for anomalies!" ”

"What anomaly?" Bai Sha asked.

"I don't know!" Qingshi shook his head and said, "However, I also believe that the Stone Forest Passage is still there, and what we see must be an illusion." Since it is an illusion, then it must be fake, and since it is false, then it must be different from the real thing, and this difference is what I call 'abnormal'. ”

"Hmm......"

Everyone nodded thoughtfully, then looked around again.

"What's different is the anomaly?" Anan suddenly said, "That'...... Is that the same place abnormal? ”

"What's different?" Luo Luoshan scolded, "What kind of strange things are you talking about! ”

"When I didn't say it...... Anan muttered aggrievedly and was about to walk away.

"Wait!" Qingshi stopped Anan, "What do you mean by what you just said?" Does it mean that you see two identical things? ”

"yes," Anan said, "I noticed that there are two dunes that are exactly the same shape, is that an anomaly?" ”

"Grandma's!" Duan Wutian shouted, "There are thousands of sand dunes around me at a glance, and I see all of them as a ball, but when I look at them again, they are all not balls." ”

"Not really!" "Only two of them are identical, and the others are not the same. ”

"Really?" Qingshi happily asked, "Great, it turns out that you still have this talent, tell me quickly, which two sand dunes are exactly the same?" ”

"That's it and that!" Anan stretched out his index finger and poked it in each direction.

Of course, he just pointed twice, and no one could know what he was referring to, including bluestone.

"What's this, that," Luo Luoshan frowned, "Explain it to Lao Tzu!" ”

Anan pointed and gestured and explained, and after a long time, Qingshi and Luoluo Mountain finally understood what Anan meant.

Indeed, there are two small dunes that look exactly the same in two different directions, and the background around them is the same, but the dunes are a little more prominent.

It is said to be conspicuous, but in fact, in the vast desert sand sea, looking at all sides, almost all the sand dunes are similar in shape, color and background, almost the same, to find two identical sand dunes in different directions in the distance, the difficulty can be imagined.

As Duan Wutian said, in the eyes of most people, these sand dunes are almost the same, but in fact, they are their own appearance.

"It's a mirror!" Qingshi nodded and said, "Now it can be determined, one of these two places must be real and one of them fake, and the hidden one behind the fake one is the Stone Forest Passage." ”

"Great!"

Everyone was excited, and they all said that they should immediately organize two teams to go to these two places to check, but, after all, no one is making their own decisions now, including Luo Luoshan, everyone unconsciously looks at Qingshi, waiting for him to decide on the next move.

"Brother Haiya!" Luo Luoshan said, "From now on, it is up to you to arrange and direct how to act." ”

Naturally, everyone agreed.

"Good!" Qingshi didn't give in and said, "There's no need to send two teams to go separately. Which one is true and which one is false, just try it and you'll know. ”

After speaking, Qingshi waved his hand and took out his black bow and Xuanfeng arrow, and then opened his bow and shot an arrow.

I saw that the long black arrow drew a wonderful arc, flew out more than two hundred zhang, and gently inserted into the top of a low, inconspicuous hill, which was naturally one of the two identical sand dunes.

Although the black arrow was far away, everyone could still see it clearly against the brown background. Since it is inserted in the sand dune, then the sand dune must be real.

So, everyone turned their heads to look in the other direction, and sure enough, a small black spot appeared on the other identical small sand dune. Obviously, this latter sand dune is a reflection of the image of the previous one, and behind this image, there must be a hidden lowland stone forest, that is, the entrance to Shenlong City.

After determining the direction, everyone had no doubts, so after making some preparations, they set off towards the goal. In order to prevent confusion after walking down the sand dune, Bluestone shot five black arrows in the right direction, each with a distance of no more than fifty zhang, and would not fall out of sight.

Everyone walked down the sand dunes, aiming for the bluestone arrows, and sure enough, as they traveled, the sun's position inadvertently shifted. Although they did not know what was going on, they only used the arrows on the ground as a reference, and did not pay attention to the sun's mischief.

The distance of more than two hundred zhang was quickly completed, and Qingshi retracted the arrow as he walked, and when he walked to the place where the last arrow was, everyone could see that in the air ten zhang away, there seemed to be a transparent energy force field distorting and shaking slightly.

Qingshi took the lead and stepped forward, and when he got closer, he could see that there was indeed an energy force field here, it seemed to be a huge mirror with water ripples, and it seemed to be a large specular sphere of steaming steam. The figure of bluestone was reflected by it, resulting in a slight distortion and deformation.

Qingshi stretched out his arm and gently touched the boundary of the mirror force field, and as his hand stretched forward, the arm seemed to be swallowed by an invisible mirror, but Qingshi didn't feel anything unusual.

Qingshi was still the first time he had seen such a formation technique, and he couldn't help but be a little curious, and he was carefully observing and experiencing its magic, Luo Luo Mountain Duan Wutian and the others couldn't wait to come over, and without saying anything, they directly crossed the mirror interface and disappeared into it.

The mirror image shook for a while, and the enchantment became unstable, it no longer completely reflected the yellow sand and the human figure, but some large and small irregular hollows appeared on the mirror, through the holes, you could see the figures of Duan Wutian and Luo Luoshan and others behind it.

Qingshi also took a step forward and stepped over the mirror interface, his body didn't feel anything, the scene in front of him changed, and it was the lowland stone forest that appeared.
