Chapter 125 Underground World
After kicking the strange fish back into the underground river, Bifang hurriedly moved to the riverbank to avoid being attacked by the strange fish again.
The river flows quietly, and the fish swim in circles in the water. The whirlpools of light they form are dazzling. These fish are actually glowing!
The fluorescence can even allow Bifang to see this magnificent place clearly!
What an incredible miracle of life!
Is this intracellular or extracellular luminescence?
Why is it so bright?
The phenomenon of bioluminescence is not uncommon, the most famous of which is the firefly on land.
There are so many luminous fish in an underground river. What kind of species are they?
Gu Qingyuan had fallen into deep thought, but Wu Gang beside him did not have so many complicated thoughts. He was simply immersed in such a vast and unknown underground.
So exciting!
The moment he looked over, Bifang forgot the danger just now, and had an urge to kneel down and worship.
He had never imagined that there could be such a vast underground space in the world, perhaps hundreds of feet, or perhaps thousands of feet.
He was unable to measure the huge cave with his own eyes. When he stood up and looked, the end of the underground river was hidden in the darkness and he could not see clearly where it flowed.
The sound of dripping water echoes monotonously in this huge space. A fairly wide underground river meanders like a river in this world, and the stalactites accumulated over thousands of years are the mountains here.
Suddenly, there was a sound of churning water, and a large shiny fish that Bifang had seen before suddenly jumped out of the river!
It seemed to have been diving for a long time, and now it was shining brightly. As the only source of light in the darkness, it was so bright that it was even a little dazzling.
Bifang squinted his eyes and took a step back, but was tripped by a stone behind his feet and almost fell.
[Oh my god, this place is too big, right? ]
[Is there a cave this big? We just dived down to about 20 meters, right?]
[Brother, have you forgotten that this is a valley? I estimate that this place is probably more than 60 meters above the ground...]
[I will never go to the Jiaofangsi again. I give this to the anchor Dagu*1. —Praise Nature]
[messier64 presents the anchor Langya*1.0000—After sailing across the ocean, we finally see land, it’s so beautiful. ]
Compared to everyone else's sighs, Gu Qingyuan was not so shocked by the vastness of this world, or rather, he had expected it.
"Just as I guessed, whales can only be bred in the ocean. You can't raise big fish in a fish tank! If you want to raise a three-meter-long carnivore, then this underground river can't be small. It must be ridiculously large!"
"But with such a big river, why is Qaidam still a desert?" Wu Gang asked puzzled.
The underground water resources are so abundant, but the ground is so dry that people don’t poop and birds don’t lay eggs. What’s the reason?
Hearing this, Gu Qingyuan glared at Wu Gang and said, "Do you think the desert is a desert just because of the lack of water? You are so ignorant!"
Wu Gang scratched his head. He didn't study geography...
"In the Arabian Desert, there are occasionally heavy downpours that can even flood cities in the desert. But even so, strong rainfall cannot change the nature of the desert, because with the infiltration and evaporation of the desert, the water will disappear without a trace within a month."
"It is impossible to transform the desert simply by relying on plenty of water!"
"And this underground river is at least tens of meters deep..." Gu Qingyuan wanted to explain, but when he saw Bifang moving, he immediately retracted his attention and waved his hand at Wu Gang with some disdain, "Alright, alright, go look up the paper yourself, I don't have time to answer your questions."
Wu Gang: “…”
Bifang staggered a few times, then sat down to rest with his back against a stalactite column.
He combed his wet hair with his hands, shaking off the dripping water stains. Under the bright sunlight, his face looked extremely pale.
Bifang shook his head, saw the barrage, and continued to answer some questions from netizens.
"The basin is surrounded by high mountains. After the meltwater and precipitation from the mountains enter the desert geology of the basin, they will seep into the ground and form groundwater."
"For example, in the Tarim Basin, Chinese geologists even believe that the groundwater resources in the Tarim Basin are much larger than the water storage capacity of Lake Baikal, the world's largest freshwater lake. The situation in Qaidam is similar."
“But after seeing it with my own eyes, I still feel shocked. This is simply an underground world!”
Bifang raised its head and breathed in the air greedily, not afraid of the poison.
"Many people watch some movies in which the protagonists encounter suffocation in the cave or toxic gas. We don't need to worry about the former because we have Tiktaalik here. If there is a lack of oxygen in the cave, they will not reproduce so smoothly."
"As for the poisonous gas, it is usually caused by the accumulation and fermentation of bat droppings, resulting in excessive ammonia in the air, or sulfur dioxide or something like that. However, these gases generally have a strong smell. I didn't smell anything unusual, so there is no need to worry about it."
Bifang took off the backpack in front of him, checked it carefully, and breathed a sigh of relief.
The backpack provided by the system is a double-layer waterproof bag, and it is tough enough. After being bitten by the strange fish, only the first layer was rotten, while the second layer was not broken, and the clothes in the backpack were dry.
Although it was not too cold, Bifang could feel that his wet clothes were taking away his body temperature.
He pretended that the camera was removed again, the drone reappeared, and then he took off his lining and put on a new one.
The beautiful figure revealed during the process aroused crazy envy among the netizens.
[The drone finally appeared. I almost vomited just now]
[Plus one, it’s so uncomfortable, even more uncomfortable than when I play 3D games]
[Isn't Lao Fang's figure too good? ]
[I love this muscle]
【Envy, envy】
[Screenshot as screen saver]
[When can I also develop a body like Fang Shen? ]
[Live outdoors often, fight against bears, wolves and snakes from time to time, and within half a month, you will be able to do this. ]
Bifang ignored the teasing of the netizens and closed his eyes. After a few minutes, when he opened them again, his eyes had initially adapted to the darkness.
The lights on the drone had long been turned off, and in the dark cave, the only light was the flowing underground river.
Bifang did not light the torch.
Before going into the water, he picked a lot of flower sticks, but since there was still light, even if it was very weak, he should not waste resources.
The surrounding terrain was blurry, and Bifang tried hard to picture it in his mind.
"Cave exploration is a very fashionable sport abroad and a popular activity for many extreme adventure sports enthusiasts. However, it is an adventurous sport after all. Most people only focus on the mystery, excitement and fun of cave exploration, and often ignore the many hidden dangers."
"Especially in an unknown cave!"
"Here, we have no road signs or guidance, nor any accurate reference points. Everything is unknown. We may not even know how long, wide, or deep the cave is!"
As soon as he finished speaking, Bifang moved forward into the darkness. Water drops fell, echoing monotonously in the huge cave.
Getting lost, rising groundwater levels, dangerous creatures, suffocation due to lack of oxygen, abnormal temperature and humidity...
Amid the pitch-black environment, a few short words echoed in the cave, constantly resounding, causing the fans' hair to stand on end. The joy of escaping from the monster's mouth disappeared in an instant.
In such a deadly environment, can humans really escape?
