Wan Lin lay behind the rocks and slowly swept through the scope to the scene in front of him. Under the cold moonlight. There are a few large trees that are more than one person thick growing scattered around. The roots of the tree are intertwined and raised high. The lonely few large trees contrasted with the dense forest behind them.

The original soft ground in the forest. It has been turned into undulating hard stones. It was covered with slippery moss.

Wan Lin raised the muzzle of his gun and looked forward through the scope. Not far away is an undulating hilly terrain. But there are few trees on it. In the distance, however, there is still a dense forest swaying in the wind. Wan Lin raised his gun and observed behind the stones for a while. Gently patted the little flower next to him.

The little flower then jumped out from behind the rocks and ran forward. Wan Lin also crawled forward. He writhed back and forth like a snake on the slippery stones. It's blazing fast. In the blink of an eye, he crawled forward for four or five hundred meters. Then he stopped behind a protruding rock. The first time it was updated, and Xiaohua was running around slowly. The blue light in the eyes flickered.

Wan Lin quietly felt the movement around him for a moment behind the stones. Then he slowly stretched out the sniper rifle from the side of the rock. Leaning over to the gun, he stared ahead at the sniper scope. His eyes immediately widened. My heart suddenly jumped wildly: in front of me was a big dark pit with no bottom. If you were a little careless just now. will plunge headlong into the bottomless abyss in the night. More and faster chapters are here.

Although he heard Xiao Wan Miao say that there was a deep pit here. But I was still taken aback by this. In front of the rock is a deep pit with a radius of tens of thousands of square meters. It's like a huge flat land. It was as if he had suddenly fallen into a bottomless abyss. Bottomless in the middle of the night.

He took a closer look around. Then he leaned forward in front of him. The muzzle of the gun was aimed at the bottom of the pit. Under the faint moonlight. The pit sinking deep into the ground resembles a giant funnel. The pit thousands of meters deep was covered with lush vegetation for the first time. Countless animal eyes with green and red eyes. Looming in dense vegetation. There was a faint murmur of running water coming from below.

Wan Lin couldn't help but sigh in his heart. Although the night is too dark to see the bottom of the pit. It can be seen in the flashes of light below. It can be seen that this is simply a paradise for animals and plants.

Wan Lin stretched out his hand to feel the temperature inside the pit. More and faster chapters are here. A wave of hot air was slowly rising. The temperature around is significantly warmer than outside the pit.

He stared curiously at the bottom and thought: I guess the pit acts as a natural shield. Below is definitely like a big greenhouse, with spring and lush vegetation. In addition, there is a natural water source at the bottom of the pit. It is very suitable for the growth and reproduction of animals and plants. Seemingly. The terrain here is really the sinkhole that Lingling just said.

He carefully observed the walls of the pit around him...... In the dark, the walls of the pit around me felt very steep. There is no way to see the passage that can be accessed from the outside. But when he aimed his scope at the eyes of the animals that flickered in the sinkhole. I suddenly wondered in my mind: there were so many animals in the pit. Where do they get from to the bottom?

He wondered in his heart. Out of the corner of his eye, he suddenly caught a glimpse of the mountains about a kilometer to the side. Several wobbling, glowing green dots appeared. Xiaohua stood up sharply from his side at this time.

Wan Lin hurriedly reached out to block Xiaohua's eyes. I'm afraid that the blue light coming out of its eyes will scare those animals away. He was trying to see where the animals were coming down.

The few flickering points of light came to an abrupt halt at the edge of the sinkhole. Looked around. Wan Lin quietly pointed the scope in front. As the string of green glowing dots moved. Several flashing red shadows appeared in the scope. It looks like a small wolf pack. There are about five or six of them in the first update.

A few dark shadows looked around vigilantly from the edge of the pit. Then a wolf ran down the edge of the pit and cautiously ran down. The next few followed.

Wan Lin watched them as they ran. from the movement of the point of light. He could see that the dark pit wall was not a cliff that went straight up and down. It's a steep slope with a slope. The wolves circled down below, left and right. A little bit of a downward movement.

Wan Lin then raised his wrist and looked at his watch. from the speed at which the wolves are running downward. The depth from the bottom of the pit to the top is calculated.

More than half an hour later. The wolves finally descended to the bottom of the pit. Then the green spots of light disappeared. Wan Lin Mo calculated. Cut out the time the wolves run sideways on the road. This sinkhole is about two kilometers deep.

Wan Lin calculated the approximate depth of the sinkhole. I couldn't help but be a little surprised. During his training, he listened to instructors explain the formation of sinkholes. Know that this is a special phenomenon in geology.

Sinkholes are generally found on karst landscapes. And there will definitely be a raging underground river underground. Thick limestone layer beneath the ground. Tens of millions of years of long-term erosion by underground rivers. Gradually, huge holes are formed under the rock.

And there will be plenty of precipitation. Abundant rainwater seeps down the rock formations into the ground and gradually collects into the underground river. Forming a turbulent and churning current in the river channel.

The raging water constantly washes away and erodes the surrounding rocks. And the rock formations that continue to erode and collapse are carried away along the raging underground river. The space of the underground cavern is gradually expanding. Finally, under the sudden action of external forces such as changes in the earth's crust. Causes the rock formation above the hole to collapse suddenly. This huge sinkhole was gradually formed.

Although Wanlin has grown up in the mountains and forests since childhood. I've never seen such a huge sinkhole. I secretly marveled at the power of nature. He observed for a while, but found no trace of the enemy. Then he whispered to the team members behind him to come to the edge of the pit.

Xiao Ya and a few people came to Wan Lin's side and lay down. They stretched out their heads to look at the pit in front of them, and they were all stunned. Lingling raised her hand and patted the hard rock beneath her. Whispered, "Oh my mother." It's really a sinkhole. In the past, it was often heard that dripping water pierces stones. I didn't believe it all the time. Now see this sinkhole washed out by the water of the underground river. There is nothing impossible in this world. Nature is amazing. ”

Everyone around them nodded slightly. All lying on the rocks at the edge of the pit. Looking through the scope on the gun's body, he looked at the dark pit below.

At this time. On the edge of the forest in the distance. One after another, some shiny animal eyes appeared. They cautiously ran from different positions towards the sinkhole.

As the night gets darker and darker. The eyes of the animals in the pit appear brighter. One by one, the glowing dots are shaking. Occasionally, a few herbivore whining sounds can be heard.

Several people understood it in their hearts. The huge sinkhole is apparently home to numerous herbivores. And the animals who have just ventured from the outside along the steep stone wall into the pit inside. Apparently some beasts of prey had gone down in search of their prey.
