At first, Qiao Hua thought the blue light was the reflection of the stars in the sky, but later he discovered that even on a dark night without stars, a faint light would still appear in the sinkhole, like thousands of fireflies gathering at the bottom. . The blue halo looks very beautiful. But if you add some unknown color to this light, it would actually be more weird and terrifying to Qiao Hua. Although Qiao Hua knew that there must be many secrets hidden in this place, the fear that surged in his heart forced him to consider leaving here. "Roar!" The dwarf tyrannosaurus called out to the little squirrel digging a hole with its claws over there, and then crawled forward and hurried forward. He only hoped to escape from this somewhat magical place before night came and find a suitable habitat. Although Qiao Hua is confident that he can deal with one or two super-large beasts, if the opponent comes in a group, he may not be able to escape unscathed. Thinking of this, the dwarf tyrannosaurus couldn't help but speed up its movements. Although his body was completely covered by the long grass, he still made as little noise as possible just in case. Soon it was ten o'clock in the evening. Guo Ke's eyelids couldn't stop fighting at first, but later he curled up into a ball and fell asleep completely. But the dwarf tyrannosaurus underneath it didn't feel any sleepy at this time. Qiao Hua found that this area was much larger than he thought. Even though he ran all the way, he still couldn't escape from this place with dense grass and tall trees. It's almost sunset now, and it looks like we have to spend the night here. Just when Qiao Hua was about to find a suitable place to spend the night, he suddenly heard a slight noise from ahead. His body couldn't help but pause for a moment, and then slowly leaned over. A few steps later. The originally dense weeds suddenly disappeared. What was displayed in front of this dwarf tyrannosaurus was a huge pit nearly a hundred meters in diameter. The noises Qiao Hua heard just now were caused by the big fish slapping the water. Qiao Hua couldn't help but feel happy secretly. If it weren't for these tiny sounds, at the speed I was going just now, it would probably be because of too much inertia. I couldn't stop the car for a moment and fell into this deep pit. Standing on the edge of the sinkhole and looking down, I saw some big fish swimming slowly inside. Each fish looked bloated. It seemed that there should be a lot of food underwater. From a height perspective, the entrance of the cave was almost twenty meters away from the water surface, but Qiao Hua could not judge the depth below the water surface. The walls of the pothole are very smooth. It was covered with a thin layer of moss-like plants, but there were still two or three small trees growing diagonally from the gaps between the stones. And on those weird branches, there are many skeletons of creatures hanging. Obviously, not every animal is as lucky as Qiao Hua, but there are many who fell into the pit. He starved to death inside because he had no chance to climb out. Of course, there may be more that have been buried in the belly of the fish. Although to Qiao Hua, such a scene does seem a bit shocking. But this also aroused his curiosity, so the dwarf tyrannosaurus decided not to rush and stay here for one night first. The sun sets toward the west, and the sky gradually becomes dark. The core could no longer bear the loneliness and went looking for something to eat. However, what disappointed the little squirrel was that there were only those with red fruits around. The remaining trees only grew leaves but not fruits. After searching for the fruit pits for a long time, I found nothing, so I simply lay on the branch and stopped moving. At this time, Qiao Hua looked into the pit with a face full of surprise. inside. The blue light was becoming brighter and brighter, not only allowing the fish inside to be seen at a glance, but also showing the entire bottom of the pit in front of Qiao Hua. Just as the dwarf tyrannosaurus guessed, there were animal skeletons of large and small piled up under the water. The will-o'-the-wisp blue light shone on those already somewhat decayed skeletons, like a scene in hell, more terrifying than the dinosaur tomb that Qiao Hua saw last time in his hometown. Qiao Hua guessed that the luminous object under the water should be a substance similar to fluorescence. The light will disappear automatically after the UV rays stop irradiating for a period of time. However, it turns out that after a long time. The light emitted from the bottom of the water still appeared to be very sufficient, showing no signs of weakening at all. and. Attracted by this light, many huge flying insects that were originally hiding in the grass gradually gathered towards the water, and then threw their bodies into the water without hesitation. "Crash-" The fish underwater suddenly started to stir. The fat fish began to scramble to eat the large flying insects that landed on the water, and they were extremely crazy. It was only then that Qiao Hua finally understood that the reason why these big fish became so fat did not rely on the cycle pattern of "big fish eat small fish, small fish eat shrimp, and shrimp eat mud", but because of these blue fish under the water. The effect of color light. Qiao Hua became more and more interested in this huge pit and the blue light emitted from it. He could think of only a few possibilities for the formation of this deep pit: explosion of combustible materials underground, collapse of karst materials or loose debris, meteorite impact, etc. But none of these can explain why there is blue light inside. Qiao Hua remembered that he had heard that some rare gems could emit light at night, such as luminous pearls. Could it be that there are some rare minerals stored at the bottom of this big pit, which is why this situation occurs? "It's a pity that no matter how precious the mineral is, it has no meaning in this era. At best, it can only attract some food to the underwater fish. That night, Qiao Hua fell asleep under a big tree not far from the pit. Because he was afraid of being attacked by large animals, Qiao Hua didn't fall asleep until nearly dawn, causing him to still feel hazy after waking up. As soon as the dwarf tyrannosaurus stood up from the ground, it felt something furry on its back, which seemed to be rising and falling rhythmically. It turned out that when he fell asleep, the little squirrel Nuoke jumped down from the tree at some point, lay on his back and continued to sleep. So Qiao Hua did not disturb the little squirrel and quietly started his whole day's journey. From morning to noon, this dwarf tyrannosaurus saw several guys much bigger than itself along the way. However, because he had already heard the movement ahead, he had already crawled away from the grass before encountering the opponent. But what confused him was that after half a day of non-stop advancement, he still couldn't break out of this weird area. Nima, how big is this place where the grass is deep and dense?
