The next moment, I felt myself hit a rock hard, and the pain was too much for me to think, and at the same time, I heard a gunshot in my ears. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

I slowed down a little, and when I looked closely, I found myself lying in a huge canyon, and in the gap at the mouth of the valley were the corpses of the trees, which were desperately squeezing into it, and the fawn was holding the eight-one bar and sweeping it at their heads.

Because the entrance to the canyon is very narrow, the tree corpses are very easy to fight together, almost no bullets, guns and headshots, Uncle Li is not to be outdone, snatched the box cannon from me, and raised his hand is a shuttle.

Surprisingly, they don't kill their heads like the zombies in the game, but just take a few steps back and pounce on them.

"Uncle, didn't you say they wouldn't come down from the trees?!" I shouted.

"I mean, they're going to die when they come down! Wait a little longer, they shouldn't last long, and they will live two minutes at most if they leave that tree! Uncle Li said, while still busy shooting.

This kind of scene is the same as the game dungeon, a few people crouch in the gap, and shoot wildly at the monsters that are about to enter, although the firepower is very strong when the fire is concentrated, but there is a fatal weakness is reloading! If the timing of several people's bullet changes is accidentally synchronized, there will be a short interval between firepower, during which no one shoots, and the monsters will take advantage of the situation and annihilate us in one fell swoop.

The box cannon was originally a small magazine and a fast rate of fire, and it was shot in less than a few seconds, but unfortunately, the fawn also ran out of the remaining bullets at this time, and before we could react, those tree corpses instantly swarmed over, and the brains were full of holes left by bullets.

"What are you doing? Run! Uncle Li shouted hoarsely.

I immediately struck a nerve and ran after them into the canyon.

As the groundwater gushed out of the crevices and the rivers that merged into the crevices became deeper and deeper, we had to move against the walls, and the speed of the corpses was so fast that we stumbled forward, and there were a lot of colors on our bodies.

"What's going on? Didn't you say that a good one doesn't live for more than two minutes? It's definitely been two minutes now! I asked, gasping for air.

"How do I know, don't worry about it, it's important to escape!" Uncle Li said.

Suddenly, there were several howls behind us, which sounded a little miserable, and we hurriedly turned our heads to look, and saw the corpses stopped, squatting in the water with their heads in their hands, and their expressions were very painful.

"No, this thing has such a long reflection arc? I was shot just now, and now I feel pain? I was surprised.

As soon as the words fell, their heads fell down, their hands lost their strength, and they fell into the water one after another, splashing more than ten meters!

We watched in horror as if we were watching a disaster movie, and the spectacle was no worse than those computer special effects.

"They're dead, aren't they?" I asked.

Uncle Li let out an "um", obviously not yet relieved from the thrilling just now.

After being stunned for dozens of seconds, I came back to my senses, remembered my previous doubts, adjusted my breathing briefly, and asked Xiaolu: "What happened just now, why did you float in the air, and this ...... All of a sudden, it's back to a canyon? ”

Xiaolu raised his eyebrows lightly, pretending to be mysterious: "I have superpowers!" ”

I punched him and said angrily, "Don't make a fuss, seriously, what's going on!" ”

He snapped his fingers and began to explain, "Do you know about polarized light? In fact, light is an electromagnetic wave that can emit signals of different wavelengths in all directions, but if it is transmitted by a special substance, these lights can only vibrate in one plane, then it becomes polarized light. ”

"What?" I was completely stunned, and I thought to myself that this kid must be talking nonsense again, bullying those of us who don't understand physics!

"To put it bluntly, it's like a little trick in magic, there's something in front of you, you can only see it from one range, and when you leave this line of sight and change the angle, you can't see anything, only a cloud of black." He continued, "I was looking at the trunk of the tree just now, and it was pitch black all the time, like an abyss, and when I jumped on the branch, I saw a canyon, and I realized in an instant that I could only see the canyon above the trunk of the tree, and when I came down, I couldn't see anything. ”

I seemed to understand a little, but I still couldn't fully digest it, so I roughly sorted it out and asked him, "Then how do you get the polarized light you are talking about?" ”

"It's similar to the principle of refraction and total reflection, where light passes through a special nicol prism to produce polarized light. I just observed that there are a lot of white grains sticking to the side wall of the gap, which should be formed by the crystallization of impurities in the air, due to the change in the nature of the air flow at the gap, these grains will be enriched here, forming a natural barrier, its structure is similar to that of a nicol prism, which is why we can't see the canyon on the ground! ”

After listening to his tirade, I felt like my head was about to explode, but fortunately I didn't study physics, otherwise ten brains would not be enough.

"Can you say something we understand?" I smiled wryly.

"Hey, these are just my conjectures, I'm not sure if it's right or not, but I trust my instincts can't be wrong."

I said in my heart that this guy will really find himself under the stairs, anyway, Uncle Li and I don't understand, it's not up to you to decide!

Uncle Li sighed and said helplessly: "Hey, whatever!" Now that you've found this place, let's move on, there's no turning back anyway! ”

Come to think of it, it's good to leave the brain-consuming things to the fawn, so why should I bother with these esoteric and complex principles? I won't be able to win the Nobel Prize in the future......

We gathered our mood and set off again along the riverbank.

The whole canyon seems to be naturally formed, with obvious signs of erosion on both sides, which is similar to the reason for the formation of sinkholes before, and this geological structure often takes tens of millions or even hundreds of millions of years of evolution to obtain, I can't help but sigh at the wonder of nature.

Further up, there is the sky covered by vegetation, and the mottled branches and leaves make the whole canyon look gloomy, and I don't know what the situation of the people above is now, I hope that Ah Mo can show mercy, after all, the person he wants to take revenge on is Uncle Li.

The canyon stretched straight forward, but due to the light, we couldn't see too far away, and we didn't know how long we had to walk, and the physical exertion made us not have the strength to talk much, and it was very painful to walk all the way down.

Suddenly, I tripped over something, lost my balance, and almost fell into the water, but fortunately the fawn reacted quickly and pulled me in time, otherwise I would have had to wash my lungs again.

At this moment, I suddenly saw a group of people sitting in front of me, and because of the distance, I could only barely see some figures, and they were sitting in the middle of the canyon, with a strange thing beside them.
