Ancient Invasion [End Times]

No. 40 days after the invasion. [First update] The dry Lindu River

Du Nanrong looked at his saxifrage, no matter how he looked at it, he felt delighted and cute.

It's just that the rhizome is covered with a ball of mud, which is really pitiful. Du Nanrong decided that if he saw any flower pots in the future, he would bring one back and make a home for the saxifrage.

After rushing out of the ginkgo forest without any risk, the group of them finally left Rindu.

Looking back, Du Nanrong felt that there was nothing wrong with the ginkgo forest standing in the outskirts, at least the threats from outside couldn't get in.

They are like silent giants watching, guarding Rindu.

Outside Rindu, there is an inland river winding around Rindu, called Rindu River.

The water in the Lindu River has dried up, exposing the bare riverbed, and there are all kinds of fish and shrimps that died of drought.

The trucks drive along the banks of the Rindu River.

Lin Qian glanced out the window while driving, seeing dead fish and shrimps all over the river bed, the scene was startling.

He muttered in a low voice: "Why did the Lindu River dry up?"

Cheng Sheng didn't know when he came to the side of the cab. He looked at the long river passing by outside the window and said, "Actually, the total volume of the Lindu River has been decreasing sharply every year in recent years."

Lin Qian didn't expect Cheng Sheng to come over, he nodded slightly to greet Cheng Sheng: "Doctor, you are here."

Cheng Sheng nodded, and continued: "The Lindu River is an inland river, and the flow of the river is closely related to the climate and environment. Now that the temperature is constantly high and the area is dry, the environmental experts in the compound have predicted that the Lindu River will stop flowing next year. "

He looked out of the window and said softly, "I just didn't expect this to happen so quickly."

Cheng Sheng looked out the window, and his eyes suddenly focused on a river bed not far away.

He half-closed his eyes, and suddenly added: "On the other hand, the infiltration of the riverbed is serious, and the evaporation loss at the bottom of the water is too large, which may also be a major reason for the stagnation of the Lindu River."

"Ah?" Lin Qian heard that the doctor's words meant something else, but he didn't understand, "Infiltration? Bottom evaporation?"

Cheng Sheng didn't explain, but just pointed in the direction, and said to Lin Qian, "Lean towards that section of the river."

"Oh, good." Lin Qian responded, turned the steering wheel, and looked at the place Cheng Sheng was pointing at.

Duan Yi noticed that the direction of the car had changed, he got up and walked to the cab: "What's wrong?"

"I need to check some things." Cheng Sheng looked at Duan Yi, "I need to go to the river bed."

Lin Qian blinked and remained silent.

"Must?" Duan Yi asked.

"It may affect the living environment in the future, but I hope it's just me being too vigilant." Cheng Sheng looked at him.

Duan Yi understood, he asked Lin Qian to stop the car on the spot, keep the engine running, and stay in the car.

He and Cheng Sheng got out of the car and went to the river bed alone.

Xu Ying opened the iron door of the back door of the carriage, held a gun in his hand, and alerted Duan Yi and the doctor to the situation around them.

Luo Xiaonan watched Cheng Sheng go down to the bottom of the river bed alone, and looked up at Du Nanrong blankly: "What is the doctor going to do? Catch fish?"

Du Nanrong glanced at the dead fish in the riverbed, most of them were surrounded by flies and insects, he twitched the corners of his mouth, and instilled common sense in Luo Xiaonan: "Nannan, you can't eat meat with flies and insects flying on it."

"Then what is the doctor going to do?" Luo Xiaonan blinked and asked.

"I don't know." Du Nanrong replied honestly, he didn't just make excuses to prevaricate Luo Xiaonan, he said, "There is a reason for everything Dr. Cheng and Duan Yi do."

He let out a "huh" and said, "After they come back, Nan Nan will ask them again."

Luo Xiaonan nodded obediently, and turned his gaze to the doctor again.

There are no creatures within [-] meters around the entire river section, and it is clearly visible and safe within the visible range.

Because of the circumstances, Duan Yi agreed to Cheng Sheng to get out of the car to check the river situation.

The bottom of the river bed is very uneven, and there are reef bumps. Cheng Sheng's wheelchair is not suitable for traveling in such a place.

Cheng Sheng was bumped by the rocks below for a short distance and felt dizzy. He frowned and said to Duan Yi, "Da Bing, come and hug me."

Duan Yi was stunned for a moment, then bent down and picked Cheng Sheng up from the wheelchair.

The weight in the hand is not light. Although it is not the first time to hold Cheng Sheng, Duan Yi is still slightly shaken by the soft but muscular feel of the hand.

The doctor's waist feels really good.Duan Yi has a serious face, no one knows what he is thinking in his heart.

Xu Ying, who was staying far away on the collection card, holding a sniper rifle and opening the scope to guard: "..."

She rubbed her nose and guessed that there was some special situation. The doctor's wheelchair was not easy to move. Just as she was thinking about it, Du Nanrong curled her lips in wonder, and said, "Why are these two people hugging each other all of a sudden?"

Xu Ying coughed lightly.

"Do you need me to help?" Du Nanrong continued.

Xu Ying said "oh", it turned out that Du Nanrong meant that.

She thought for a while and said, "It shouldn't be necessary. If there are special circumstances, the Duan team will give the signal."

Du Nanrong nodded.

Cheng Sheng was held by Duan Yi, and he directed Duan Yi to stop wherever he went.

Dabing's pace is steady and fast, and his body temperature is just right, which is very easy to use.

The doctor was very satisfied, and then asked Duan Yi to put him down.

He took out the gloves he had prepared in advance and put them on, and took two twigs he picked up along the road, which he used as tweezers, to pick up a dead fish stuck to the crevice at the bottom of the river bed.

"This fish was scalded to death." Cheng Sheng gently separated the gills of the dead fish with two twigs, and tore off the scales and bones. Some rotten dead fish were easy to disassemble, and it didn't take Cheng Sheng much effort.

After he finished speaking, he looked at the gap beside the dead fish. The gap was very wide, about ten centimeters in length. It was this gap that attracted his attention and made him want to investigate.

He scraped off the yellow and black powder on the reef near the gap with a branch, put it under the tip of his nose and sniffed it lightly, his expression was not very good.

"Smell it, what do you think?" Cheng Sheng handed the branch to Duan Yi.

Duan Yi smelled it, paused and asked, "Sulphur?"

"You think it's sulfur too?" Cheng Sheng snorted.

Looking back, he saw that the gap stretched almost the entire length of the river. The widest part was about ten centimeters wide, and the thinnest part was only about the width of a finger.

The black gaps seem to be ordinary.

Cheng Sheng opened his hand to Duan Yi: "Hold me back. Check it out."

Duan Yi responded, he glanced thoughtfully at the long and narrow gap at the bottom of the river bed, carried Cheng Sheng in his arms and walked back.

He asked in a low voice, "What do you think erupted at the bottom of the river?"

Cheng Sheng nodded slightly.

He sat back in the wheelchair, scanned the entire river, and said, "I sent the data to the base and asked Lu Weijing to find an expert to analyze it. After all, I am not an expert in this field."

The two of them quickly returned to the truck, and Duan Yi patted the cab, signaling Lin Qian to continue driving on the road.

Xu Ying closed the iron door again.

Except for Lin Qian, everyone else was sitting in the carriage. Du Nanrong, Xu Ying and Luo Xiaonan looked at Cheng Sheng and Duan Yi: "What did you find?"

Cheng Sheng and Duan Yi looked at each other, and Duan Yi nodded slightly at him.

After Cheng Sheng paused for a few seconds, he still told others what he had observed and assumed.

"Most of the fish and shrimp at the bottom of the river bed died not from drought, but from scalding," Cheng Sheng said.

Xu Ying and Du Nanrong frowned.

Sitting in the cab, Lin Qian actively participated in the discussion group even while driving. He asked, "Is it because of the high temperature a while ago? I remember someone recorded that the temperature of the water surface was more than 40 degrees."

"The continuous high temperature and no rain some time ago did cause the water level of the Lindu River to drop, but the large-scale death of fish caused by this high temperature is because the water temperature is too high, causing the fish to lack oxygen, not what I said. " Cheng Sheng replied.

"Duan Yi and I found a long and narrow gap at the bottom of the riverbed that almost crossed the entire river, and there were traces of sulfur around the gap." Cheng Sheng continued.

He looked at the others, "Perhaps you have heard that in a hot spring town on Mount Dante, two highly burned corpses of tourists appeared in a lake in the town, and sulfur was also found on the reefs near the lake. .”

"I know." Du Nanrong said, "This accident happened in 1987. Mount Dante was a dormant volcano, but during that period it was more in line with a semi-dormant state. The two tourists died because of the underground activities of the dormant volcano. ..."

As Du Nanrong spoke, his voice gradually softened, and then stopped.

"But I don't understand. Are you saying that the condition of the Lindu River is the same as that of Dantefeng Lake?" Du Nanrong looked at Cheng Sheng, "But we don't have a dormant volcano here."

"It doesn't have to be a volcano." Cheng Sheng looked at Du Nanrong and said slowly, "The uplift of mantle magma not only occurs in the ocean, but also in the depths of the continent, causing the continent to rupture and form trenches."

"And when certain conditions and factors are just met, a small amount of extremely high-temperature steam is engulfed in sulfur and erupts from the bottom." Cheng Sheng pointed to the river outside the window, "That's what we saw."

Du Nanrong's face paled: "Then you mean, we may encounter magma...?"

"No, what I'm worried about is not the eruption of high-temperature steam, or the excessive leakage and spread of mantle magma." Cheng Sheng shook his head, "The conditions and factors required for these disasters to occur are too complicated. The example of Lindu River may be Rare of the rare, don't worry about that at the moment."

Du Nanrong heaved a sigh of relief.

Cheng Sheng continued: "What I am worried about is the crustal movement of the continental plates. The junction between the plates is the zone of intense crustal movement. The extrusion, folding and fracture of the rock layer often occur. The rise of the mantle magma should also have this reason. .”

"If, as I assume, the continental plate we live in is not stable now, then small earthquakes will occur frequently in the future, and large catastrophic earthquakes may be brewing." Cheng Sheng said in a deep voice.

Du Nanrong took another breath.

"If that's the case... what can we do?" Du Nanrong asked.

"I'm not an expert in this field." Cheng Sheng looked at Du Nanrong, a little helpless and funny.

Although he is not humble, he is indeed not a know-it-all. He shook his head and said, "I only know superficially. I have sent the specific data back to the base. There are a lot of geologists there who will study and give strategies."

Du Nanrong pursed his lips and nodded uneasily.

The atmosphere in the whole car was a little dull for a while.

Luo Xiaonan also seemed to feel the solemnity of the atmosphere. He sat quietly with his plush bear in his arms, without making a sound, but opened a pair of dark eyes, looking at Cheng Sheng and the other adults in a daze.

Seeing this, Cheng Sheng pursed his lips slightly.

His intention in saying this was not to scare them or make them feel hopeless.

——he hoped that all of them would be ready, both physically and psychologically.

Duan Yi gently pressed Cheng Sheng's shoulder, and took over the dull topic.

He changed the topic: "Although we don't have any definite information and feasible strategies for the time being, since we know the possibility of this situation, we need to make some preventive adjustments in our subsequent actions and paths."

Hearing this, Xu Ying looked at Duan Yi and cheered up.

"For the next route, try to choose an open plain area." Duan Yi said, "Even if you are in a city, you must first find a key triangular life zone where you can take refuge."

"No matter what happens, I hope that my team members will not give up the hope of surviving easily." Duan Yi looked at all of them.

Du Nanrong was stunned for a moment, and then realized—has he been formally included in the team by the captain?

He pursed his lips twice, and nodded in response.
