"That's right." After hearing this, Zimeng immediately reflected on it and asked Zhou Fan, "Where did those monsters go?" ”

Tianyou Fenglong also looked at Zhou Fan when he saw Zimeng's inquiry: "I don't know about this, when I observed before, I found that they didn't seem to dare to stay there for a long time."

The beasts were very fast, they deliberately avoided the ancient building, and they just grabbed a few bronze chains, trying to break them, but did you find a single detail?

They all look up at the sky, consciously or unconsciously, and I suspect they have their own way of telling time, and they are observing time when they pull the chains.

It was already past one o'clock in the middle of the night, and just after a few hours of the morning, I noticed that the foxes had disappeared at some point, and they had not appeared until now.

I suspect they only appear at certain times, and it's likely that they don't go out during the day, only at night, just before midnight.

Otherwise, there is no way to explain their behavior, and today we will have a good night's rest, and tomorrow after noon, we will get up again to see if those beasts appear during the day, and if they do not appear, we will go up. Zhou Fan returned to the fire, picked up a piece of dry firewood, walked to the place where they were resting, three or five meters away, and drew a circle on the ground.

The place where they were at this time was black dirt of unknown composition, except for the huge stone and the flat stone floor within a meter or two around the stone.

It looks like rotten and moldy, or like the swamp in the swamps, and the dirt around it looks so soft that it looks like you'll sink if you step on it.

But in fact, this kind of black soil has a very good hardness and high density, Zhou Fan drew a circle on the ground with dry firewood, and he could only see a faint line that dived down, if he was far away, he couldn't find this shallow line at all.

Zhou Fan couldn't help frowning a little when he looked at everything in front of him, and tried to draw a circle again, but it was almost the same as the one he had drawn before, so he knew that he didn't need to waste any more time, so he turned around and said to the three of Tianyou: "Why can't you stay here, hurry up and pack up, let's find a high position." ”

Regardless of the reaction of the three of them, they picked up the backpack and ancient sword on the side and turned over and walked forward, Tianyou and the three of them saw that Zhou Fan was like this, although they had doubts in their hearts, they didn't want to ask too much, and they each lowered their heads and packed up.

Zhou Fan hadn't taken two steps before he saw a strange green light suddenly appear in front of him, this kind of green light was not like other lights, it was a cold green light in the dark, and the green light shone on the entire mountain stream.

At this time, Zhou Fan and the others had just packed their luggage and walked together in this gloomy mountain road, when the cold green light suddenly shot down from the top of the ancient building, shining on the big stone they had just rested on.

After the stone was irradiated by the strange green light, it suddenly refracted the same light, and the green light refracted by the two rays met together and shot straight into the sky, forming a green giant pillar that soared to the sky.

The four of them were so shocked that Zimeng swallowed his saliva and said in surprise: "My grass, what the fuck is going on?" Is this the rhythm of the ascension? ”。

"Roll" Feng Long looked at Zimeng with disdain: "Don't be nonsense here, this is a physical reaction, also known as the principle of optics, just like if you use a high-energy lens to put it under the sun, shine the light out and then shine on another high-energy lens."

The light from the other lens reflects the light again, but instead of shining back in the same orbit, it goes off the same track, reflecting the light elsewhere again.

If there is a piece of high-energy that can refract the reflection at this time, and the light is poured out again, then there is a chance that the light will go straight to the sky, just like the scene in front of us now, which is also the principle of optics, but to achieve the scene in front of us, there must be the three conditions I just mentioned.

The first light must have a strong luminous object at the starting point, and the second must have a lens or reflective thing that can illuminate strong light, and the refracted light must hit something that can also reflect light somewhere.

Finally, the light should be mapped again to hit the third reflected thing, and the three objects that can reflect the light cannot be placed in the same orbit, otherwise the optical scene in front of you will not be formed. ”

Tianyou was puzzled by Feng Long's words, and couldn't help asking: "But no, where did such a strong light source come from at night?" ”

"I don't know, but..."

Before he finished speaking, Zhou Fan interjected and said: "Don't discuss it here, you want to know what's going on, let's go to the front to see what it is, no matter where this light source comes from."

We just need to find the last refractive point, according to Feng Long's theory, the last refractive point must be on the ground, and this sky-high green light should not be far from us, we have time to discuss here It is better to see and understand. ”

Tianyou and Feng Long glanced at each other, just wanted to act, but saw Zimeng walking in front of them one step ahead, Zhou Fan hurriedly turned around and said hello to them, and also stepped forward with Zimeng's pace.

The four of them walked among the dark mountain roads again, and at this time, Weilou Mountain was getting closer and closer under the itinerary of the four people, and the green light that rushed to the sky was also more intense and dazzling, like a huge green light tube placed in front of them.

It's just that this lamp tube is already too tall, and the closer the four of them get to the green light, the more cautious they become, and soon Zhou Fan and the others came to a deep pool, and the four of them were stunned when they looked at everything in front of them.

At this time, there is no road in front of him, and there is only a bottomless pool, which is the size of several basketball courts in length and width, and the four people don't know the depth.

The soaring green light was shining directly from the bottom of the water, and the green light in front of them was too dazzling, and Zhou Fan had to bring his sunglasses, although it was the middle of the night, the green light had reached an extreme.

The four of them carefully observed the surrounding environment by means of the green light, and the deep pool in front of them was just under the plank road that spiraled up and carved along the mountain, if the four of them wanted to go up the ancient building from the plank road, they had to swim through this deep pool the size of several basketball courts.

But that's not realistic, although the four of them set off lightly, but there are some things on their bodies that can't see the water, although this deep pool is not big or small.

But it just happened to completely block the way on the plank road, and this deep pool is not an ordinary pool of water at first glance, and the four people below don't know, not to mention anything else, if they swim into the water indiscriminately, they suddenly drill out of a water python halfway through, and no one can deal with it.

When encountering a huge anaconda in the water, it can only be slaughtered, not to mention a human being or a big crocodile, and the report has also seen being entangled by a giant python, and Guangxi is a unique karst landform and subtropical monsoon climate.

This landform and climate are somewhat similar to the tropical rainforests of South Africa, and in this kind of deep mountain and wild forest that has not been visited all year round, it is difficult to guarantee that huge anacondas will not be raised.

"Why don't we put a hole into the water and see if there is any living creature down there, it's not a way to go on like this, we have to have someone go into the water if we want to figure it out." Just when everyone was silent, Tianyou spoke first.

"That's not good, if there's some monster down there that makes you blow up and suddenly run out, then aren't we all going to be finished here?" Feng Long somewhat disagreed with Tianyou's approach, and immediately said when he saw Zimeng's fist-rubbing appearance.

Tianyou was a little anxious when he saw that Feng Long didn't agree, so he turned his eyes to Zhou Fan: "Then what should I do?" I don't think this green light will last long, and now while there is still light below, why don't we have eye-protecting sunglasses.

At this time, we can see everything below when we go into the water, otherwise it will be very difficult for us to think about it when the light disappears, and if there are monsters, even if we have a strong flashlight, we can't see the things around us clearly, and the role of one or two flashlights in the water is very limited. ”

"I agree with Tianyou's opinion," Zhou Fan glanced at Feng Long, who was frowning, and Zimeng, who was extremely excited, and said, "I didn't know that the plank road needed to wade through the water before.

Now that this puddle is holding us back, it is very difficult to think about the past, first of all, we must know if there are any monsters down there, and if there are any other things that can threaten our existence.

Secondly, I also thought that this green light would not last long, and the light was very bright when we first arrived, but now it has obviously weakened a lot.

If it was a little later, I don't think we would have to wear sunglasses, the current light just gives us plenty of vision, so we just have to figure out if there is anything that threatens safety underneath, and as for the rest, we are thinking about it in the long run. ”
