Wu Zhiyuan's question suddenly made Moon Shadow Fuxian dumbfounded, and both of them made a mistake that was the lowest and most easily overlooked. People generally don't have doubts about what they are accustomed to, just like Wu Zhiyuan can still see more clearly when he enters the passage from outside the passage, he does not investigate the reason, if he finds that it is pitch black when he enters the passage, then he will notice that there is no light shining through the passage.

Now you can see in this passage, although it is slightly dim, but it would never have been possible without the action of light. Wu Zhiyuan looked left and right along the stone wall and made sure that there were no light troughs and other lighting things on the wall.

And where does the dim light in this tunnel come from? The two looked at each other, and suddenly felt weird and abnormal. At this moment, Moon Shadow Fuxian suddenly looked up, and at the same time stretched out his hand to the top of his head: "Look at the top of your head!" ”

Wu Zhiyuan also looked overhead, and almost screamed out of his voice. I saw that the top of the channel was flat, about two people high, and the top was densely lit with countless bright spots the size of soybeans, those bright spots glowed with dim fluorescence, and the brightness of a bright spot was faintly negligible, but hundreds of millions of bright spots were densely connected along the top of the channel, and its brightness should not be underestimated. This is the reason why you can see things not far away in this passage.

"What are those?" Moon Shadow Fuxian looked at the top of his head and asked suspiciously, "Is it a firefly?" ”

Wu Zhiyuan looked back and forth along the passage and found that these bright spots were almost paved together, spreading along the passage until the end of the turn. In this way, the top of this passage is full of these fluorescent bright spots, so you can see everything around you wherever you go.

"It's not fireflies, I played with fireflies when I was a child, this kind of bug only exists in summer, and now it's close to early winter, how can there be this kind of bug, I think, this must be something else." Wu Zhiyuan looked at the bright spots above his head and said thoughtfully.

The bright spots on the top of the head do not move at all, nor do they flicker, and it is spectacular to look at. Could it be that this is the lighting facility deliberately set up by the owner of the tomb, Emperor Xianwu, for his own mausoleum? If so, what are these lightings? Shouldn't they all be soybean-sized night pearls?

Wu Zhiyuan was puzzled, and at this moment, he only heard the Moon Shadow Fuxian say in a consultative tone: "I'll go up and have a look." ”

Wu Zhiyuan looked at the Moon Shadow Fuxian and was stunned, then nodded and said, "Be careful." The height of the top is beyond his reach, but judging from the Moon Shadow Fuxian's Yuan Qi cultivation, I'm afraid it will be difficult to pull up the height of the two of them on the spot.

Just in confusion, I saw the Moon Shadow Fuxian jump to the stone wall on the side, and then borrowed strength from one foot on the stone wall, turned around in the air, and jumped diagonally to the opposite stone wall, and borrowed strength again, and then his head was almost close to the top of the passage.

Moon Shadow Fuxian was in the air, and his sharp gaze instantly glanced at the bright spot at the top, and then he retracted his breath and fell to the ground.

"It's snails that fluoresce on it." Moon Shadow Fuxian said, a look of disbelief on his face.

"What? Snail? Wu Zhiyuan was stunned, thinking to himself, how could a snail shine? Could it be that Moon Shadow Fuxian is wrong?

The Moon Shadow Fuxian seemed to see the doubts in Wu Zhiyuan's heart, and continued: "Those snails may have lived here for a long time, and their backs are covered with a layer of white things, and it is those white things that emit fluorescence. ”

Wu Zhiyuan nodded suspiciously, it was not that he didn't believe what the Moon Shadow Fuxian observed, but he felt that the snail shell would glow, no matter what the reason, it was a little unbelievable.

"Are you sure it's really a snail on it?" Wu Zhiyuan pondered for a moment, but still couldn't help but ask.

Moon Shadow Fuxian nodded: "I'm sure, the moment I saw that it was a snail, I wanted to reach out and take one down, but I remembered that this thing might be poisonous, so I went straight down." ”

Wu Zhiyuan let out a light "um", pondered for a long time, and suddenly grabbed the hand of the Moon Shadow Fuxian and walked in one direction of the passage, saying as he walked: "Follow me." ”

The passage was empty, and there was no obstacle to moving forward, Wu Zhiyuan looked up at the top of the passage while striding forward. Looking at his appearance, it seemed that he had a strong purpose, Moon Shadow Fuxian didn't ask much, she believed that Wu Zhiyuan must be justified in doing things, this is a kind of trust sublimated from feelings.

The two of them walked around the passage, during this period, Wu Zhiyuan's eyes kept looking at the top from time to time, occasionally looking at the road in front of him, and after walking for a short time, Wu Zhiyuan suddenly chuckled, his face could not hide the excited expression, and the strength of holding the hand of the Moon Shadow Fuxian also increased.

"Right ahead!" Wu Zhiyuan looked back at the Moon Shadow Fuxian, with a smile on his face, and then pulled her forward.

Moon Shadow Fuxian didn't know what to do, and he also looked up at the bright spots at the top of the passage, and didn't find anything unusual at the beginning, but as the distance between the two of them became farther and farther away, Moon Shadow Fuxian found that the bright spots on the top were actually getting fewer and fewer, and in the end, they became stars, like morning stars.

"The exit must be behind this stone wall." Wu Zhiyuan stopped in front of a stone wall, and the Moon Shadow Fuxian looked up, only to see that there was not a single snail on the top of their heads where the two of them were standing.

"How do you know that behind this stone wall is the exit?" Moon Shadow Fuxian looked puzzled.

Wu Zhiyuan smiled mysteriously and replied: "I caught snails when I was a child, this kind of thing doesn't like to move in ventilated, light and dry places, the passage is dark and damp, it is an excellent place for them to live, so it will gather one by one, and close to the place outside the passage There is a dark wind invisibly, it is relatively dry here, snails do not like to live in this kind of place, so according to this, it can be concluded that this stone wall must be the exit." ”

Moon Shadow Fuxian also felt that Wu Zhiyuan's inference was reasonable, she turned to look at the stone wall and asked, "Then what should I do now?" ”

Wu Zhiyuan stepped forward and pushed the stone wall hard, and found that the stone wall was extremely strong, and the gaps in the blue bricks were cemented with white plaster, but the stone wall and the surrounding walls were not a whole, so it was estimated that it would not be too difficult to knock it down.

"Push it down." Wu Zhiyuan looked at the stone wall and said.

Moon Shadow Fuxian nodded, walked to the stone wall and stared at the gathering qi, and after a while, he suddenly exerted his strength, and slapped his palm on the stone wall, and suddenly the stone wall shook faintly, and at the same time, a lot of mud fell from above.

Seeing that it was effective, the Moon Shadow Fu Immortal repeated the old trick and continued to wave his palm to impact the stone wall with his vitality, and after three palms, the stone wall was suddenly shattered into a big hole with a bang.

Moon Shadow Fuxian looked forward, suddenly looked back, a look of surprise appeared on his face, and said to Wu Zhiyuan: "There is a cliff below!" ”

Wu Zhiyuan was stunned for a moment when he heard this, and before he could carefully consider the words of the Moon Shadow Fuxian, at this moment, he suddenly saw two inky black things with the thickness of the wrist sticking out from the top of the cave behind the Moon Shadow Fuxian, like snake tails, those two things shook behind the Moon Shadow Fuxian's head, and suddenly, those two things suddenly retracted, and a big black mouth stretched out from the top of the cave and bit straight towards the head of the Moon Shadow Fuxian!
