In the dark cave, Xiaoya gently pushed Yu Jing beside her, and then shouted in a low voice: "Professor Xiao, Professor Wang, Associate Researcher Hao." Before she could finish her words, Professor Xiao's voice rang out in the darkness.
"Oh, the time has come!" He quickly rubbed his eyes, and then reached out to push Professor Wang and Associate Researcher Hao who were still sleeping next to him.
At this time, a weak lightning beam had already lit up. Wan Lin stood up with a flashlight and ordered: "Check the equipment, fill the water bottle, and get ready to go!" Following his words, a group of Leopards had already stood up and put on their backpacks.
, everyone raised the water bottle and rinsed their mouths, and then they all raised their heads and took a few sips.
In the weak flashlight light, each of the Leopard team members quickly completed their preparations. They then squatted on the shore, quickly put their kettles into the puddles and filled them up. Everyone immediately stood up, carried the kettles on their backs, and raised their guns.
Looking at Wan Lin, waiting in the darkness for his order to set off.
At this time, Professor Xiao and the three of them were also busy packing their things. They filled the water bottles and stood up. Then they all looked at the group of Leopards standing upright beside them with some embarrassment. Professor Xiao then sighed: "
You are moving too fast!.”
Wan Lin looked at Professor Xiao and smiled. He raised his flashlight to shine at the small cave opposite the puddle, and then ordered Xiaohua: "Xiaohua, go in and find the exit!"
When Xiaohua heard the sound, a blue light flashed in her eyes, and she sprang out from Wan Lin's shoulder like lightning, directly jumping over the puddle and into the cave under the cave wall. Xiaobai's eyes also flashed with a red light, and she raised her tail and wanted to rush over Xiaoya's shoulder.
out.
Xiaoya quickly raised her hand and held it down and whispered: "Xiaobai, you come with us to chase Xiaohua." Wan Lin followed and looked at Zhang Wa and waved his hand. Zhang Wa immediately turned on the flashlight and ordered in a low voice: "Bao Ya,
Come with me!" After saying that, the two of them jumped directly into the deep puddle with a "plop".
Wan Lin then ordered Chengru and Feng Dao: "You two groups should follow me." After that, he looked at Xiaoya and ordered: "Your group, bring Professor Xiao and three others, come in last." After that, he mentioned
He jumped directly into the puddle with his gun, slid his arm a few times and got into the small dark cave opposite the puddle...
The cave is low, narrow, and extremely humid, giving people a sultry and humid feeling. Wan Lin held up a low-light flashlight and crawled toward the cave in front, followed closely by a group of Chengru people. The dim cave
From time to time, the whispers of Xiaoya and others could be heard: "Professor Xiao, there is a raised rock here, please pay attention", "Sister Yu, pay attention to the top of your head!"
Wan Lin climbed up the rugged cave for two or three kilometers. The cave in front suddenly became spacious, and the low roof of the cave rose upwards. The humid and hot feeling suddenly became more refreshing. Wan Lin raised his hand to take a photo.
He looked forward, then bent down and stood up. At this time, the figures of Zhang Wa and Bao Ya were dozens of meters in front of him, and the dim flashlight beam was swaying left and right with their fast-moving figures.
At this moment, Wan Lin suddenly saw Zhang and Wa in front of them stopping at the corner of the cave in front. The two squatted on the ground and looked down. Wan Lin quickly bent down and ran over with a flashlight.
Zhang Wa turned to look at Wan Lin who was running towards him and whispered: "Leopard head, Xiaohua got into a crack on the wall of the cave in front. The crack is very deep. Can you see what's going on inside?" Wan Lin ran to Zhang Wa.
He knelt down beside him and looked forward.
At this time, Bao Ya was holding a flashlight to shine on the cave wall in front of him. There were indeed twisted cracks on the dark cave wall. The largest crack was about one meter long, and the gap was about twenty or thirty.
Centimeters wide and narrow, a cool breath is pouring out from the dark crack.
Wan Lin sniffed hard, and whispered in surprise: "The air is so cool, there is a vapor in the air." He then lay on the crack and looked into the dark gap, and saw two blue eyes.
The light spots were rising and falling in the cave. Obviously, Xiaohua's sharp eyes had emitted blue light and she was running forward in the dark cave.
At this time, Chengru, Fengdao, Xiaoya and a group of people from behind also rushed over. Professor Xiao followed Yu Jing to Wan Lin. Professor Xiao squatted down and took a closer look at the twisted cracks on the cave wall.
He then turned to look at Associate Researcher Hao, who was bending over and walking towards him, and asked, "Xiao Hao, did we hear the sound of running water here a few days ago?"
Associate Researcher Hao used the flashlight in Bao Ya's hand to carefully examine the cracks on the cave wall. He then took the flashlight from Bao Ya's hand and shined it on the surrounding cave walls, and then said: "Yes, this is it! I was
I wanted to drill into this crack to have a look. It was quite spacious inside, but the rock in front of me was too hard. I hit it hard with a geological hammer a few times to try to enlarge the hole. Who knew that only a few white spots appeared on it, so it was impossible to do so.
Crush this stone wall." As he said that, he shook his head helplessly.
He then raised his flashlight to shine on a few white spots on the edge of the crack and continued: "Look, I used a geological hammer to knock out these white spots at that time." He listened into the hole and was a little surprised.
He said: "Professor Xiao, Professor Wang and I all heard the sound of running water. Why is it so quiet inside now?"
Professor Xiao, who was squatting aside, immediately explained: "This is not unusual. When there is the sound of water, it must be a heavy rain in the mountains outside the entrance of the underground river. The water level in the underground river rises sharply, which in turn causes the flow rate of the underground river to accelerate.
, so we could hear the sound of water at that time. It has been several days now, which means that the flow speed of the underground river has slowed down and the water level has dropped, so we can no longer hear the sound in the distance."
Everyone suddenly understood after hearing this. Wan Lin looked at Professor Xiao with admiration and said, "Why didn't you hear the sound of water? I was worried just now that the crack where Xiaohua entered was not the same place as you mentioned."
At this time, Xiaobai suddenly threw Xiaoya's shoulder directly at the crack in the cave wall. It grabbed the edge of the crack with its sharp claws and looked into the dark crack with red eyes. It then sucked hard for a few more times.
He lowered his little nose, flapped his two erect little ears back and forth twice, and a bright red light emerged from his two round eyes.
Xiaobai turned his head to look at Wan Lin and Xiaoya, and then raised his right paw to point at the crack, looking very excited. Wan Lin saw Xiaobai's excited look, his eyes flashed, and he immediately raised his right hand to gesture.
Said: "Xiao Bai, you also go in and take a look. If you see a river, report it to us immediately!" Xiao Bai wagged his tail and looked at Xiaoya.
