The next day, as soon as the morning dawned, a group of them set off, Professor Qiu and they drove slowly forward, Haichuan and they followed, and entered the Death Valley, obviously feeling that the temperature had become much lower, only less than two kilometers, the change in air pressure and temperature was difficult to adapt.

"You're alright. Haichuan looked at Fang Jingxuan on the side.

Fang Jingxuan nodded, "um" answered, wearing a cycling face towel and couldn't see her expression, a little girl came here with them, much more resilient than ordinary men.

On both sides are towering peaks, endless, and the white dots on the peaks are supposed to be snow caused by low temperatures, probably not deep inside, and there are still many green vegetation growing on the yellow sand.

If it weren't for those terrifying legends, not to mention that this place is really beautiful, like the rolling mountains and rivers of the Chinese painting, and a group of travelers are leisurely rushing through the canyon.

"Teacher, this is Death Valley, it's a five-star tourist attraction! You said that walking in the desert and you can enjoy the snow-capped mountains, which is much more beautiful than the snow-capped mountains in Switzerland. The fat man sighed, looking like he was late, and took out his camera to take a picture.

"Dead fatty, you make it look like you've been to the snow-capped mountains of Switzerland, how can you not pretend to be dead. ”

Haichuan observed the surroundings, the canyon is very wide, the widest distance between the feet of the two peaks is also about 100 meters, from the foot of the peak to the peak of the temperature should be high to low, it stands to reason that such a temperature difference is easy to produce a pressure difference, the air flow is very easy to form a natural wind, but here is quiet to death, as if the dust will fall vertically.

"Look at your suspicious appearance, like a cheating little daughter-in-law. The fat man teased.

Although Fang Jingxuan was also mentally prepared, if he entered the valley, he would encounter a lot of dangers, but he didn't expect that the sun was shining in front of him, and the road ahead was bright, which made it difficult for people to think that this was Death Valley.

Entering the canyon for about three kilometers, Professor Qiu and their car suddenly stopped.

"Professor Qiu, what's wrong?" Haichuan asked loudly.

They didn't seem to hear because they were some distance away, and Haichuan approached them, and found that the ground was full of animal bones, large and small, and countless.

"These are the flocks of sheep that have broken in by mistake. It was Gu Kun who spoke, and when he spoke, it always made people feel that he was sneering, but it didn't show it on his face, which made people very uncomfortable.

"These are the bones of Tibetan antelopes and large birds. Shang Bin said lightly, his expression did not change at all, as if he was stating something inconsequential.

"How can there be elephants here?"

"This vulture, this skeleton and its talons, but they have been weathered and corroded by more than half of them. Professor Qiu took out a magnifying glass and looked at it carefully, and shook his head in confusion.

"What's wrong, Professor?" asked Haichuan.

"I guess the vulture died in about a week. He said and looked at the crowd.

"Normal bacterial decomposition is never possible in a week, even under the action of external corrosive substances, the complete decomposition can only be muscles, feathers are made of fibers, and they cannot be broken down so easily. Fang Jingxuan looked at the skeleton and analyzed.

"Strong acidic chemicals are needed to clean up rusty artifacts during the restoration process, and if it is that degree of strong acidic chemicals, ......."

Before Professor Qiu finished speaking, the fat man was trembling with fat meat, and his appearance was very funny.

"Go home to find your mother?" Fang Jingxuan pointed to the way he came.

"I love the sourness and the excitement. ”

"If this corrosive substance is splashed on you, you may be even more sour!" Gu Kun joked.

"What do you mean? You're saying there's going to be a sulfuric acid rain here, and then we're going to be walking skeletons in a few seconds?"

"It was wonderful, the sound of the meat being corroded and sizzling must have been wonderful, like roasted meat. ”

"But maybe the thin person may disappear all of a sudden, and it is difficult to appreciate this kind of art. ”

The more the fat man looked at Gu Kun, the more unhappy he became, he looked lean and had a beard, he always looked smarter than others, making everyone else a fool.

"Vomit ......" was not so disgusting that Gu Qiang and Yang Jing couldn't help but vomit.

The fat man handed over the tissue: "Are you okay, look at me, how can you frighten such a beautiful girl." ”

"Don't make a fuss," Professor Qiu walked along the foot of the mountain, and found that the soil was damp, he leaned his nose and rubbed it with his hand, and walked forward on his own, repeating this action several times.

"Teacher. Yang Jing approached him.

He didn't respond, and stretched out the soil in his hand to Fang Jingxuan to see: "You are studying chemistry, you should be able to tell what this is." ”

"Sulfur!" Fang Jingxuan just handed it over and observed the color, and before he got close to his nose, he could tell it.

"How can there be sulfur stones here?" Gu Kun was obviously a little nervous.

Professor Yau pointed to the two peaks: "The ore containing a large amount of sulfur in it is shed and exposed to the sun to form sulfur dioxide in the air, and when there is rainfall, it mixes with rainwater and forms strong acid rain. ”

"Hell yes. Gu Kun scolded, he looked at Shang Bin, as if he was making eye contact with something.

"Professor Qiu, why don't we withdraw first?" Huang Cheng asked tentatively.

"It won't be so unlucky. Professor Qiu looked back at Fang Jingxuan, probably thinking that she would be relieved to agree with her professional knowledge.

"Keep going. Shang Bin shouted loudly, like soldiers carrying out orders, and the group returned to the road.

"Why did I panic when Professor Qiu said he wouldn't be so unlucky?" the fat man looked at Haichuan.

"Let you study a rainy day, it will be covered with dark clouds, and the water vapor will condense to a certain extent to form rain, do you think the dragon king will come when he sneezes?" Haichuan quipped.

"If the sun is shining, there will be no ......" Fang Jingxuan finished speaking, and the expression on his face suddenly froze.

Just now it was still a clear sky, suddenly the sun seemed to be stretched out into the dark clouds, the dark clouds everywhere came and came closer, and in an instant the sky darkened, and the flickering electric light filled the sky, although there was no thunder, but the lightning was already close in front of him like an electric snake.

"Oh no, it's going to rain. Professor Qiu looked at Haichuan behind him and shouted.

The raindrops hit Haichuan's arm, and a burning sensation that tingled the nerves came.

"Don't want the fat bike, run to the car. Haichuan took Fang Jingxuan's shoulder, took her hand, and ran to Professor Qiu's car.

"Wait for me, I can't run. ”

The thunder finally came, the rain fell through the clouds, from small to large, from slow to fast, Hai Chuan and Fang Jingxuan squeezed into the back seat in a hurry, and the fat man ran to the front The co-pilot and Gu Kun squeezed together.

The rainstorm was heavy, and the sound of sizzling on the car was the sound of corroding metal, and the weeds on both sides of the past instantly melted into the air, and the iron part of the bicycle of the three of them went out in the past, as if it was thrown into the molten iron to twist and melt, and a little bit of it was lost in the rain.

"I'll go, what do you mean, what do you mean by hesitating when I asked you to open the door just now?" The fat man stared at Gu Kun, his eyes were full of anger, on weekdays, the fat man was giggling and looking improper, even if he was angry, he wouldn't be very serious, how could the fat man sit still after almost playing the game.

"Could it be that you can't come in and let everyone die with you?" Gu Kun said indifferently, and his tone didn't seem to be discussing the topic of life and death.

"So let Lao Tzu hang first?" the fat man asked, grabbing his shoulder.

"Let it go, or I'll ...... move"

"Gu Kun!" Shang Bin howled, and he stopped talking.

"Huang Cheng, drive forward, this acid rain should only be local rain, and it should be fine if you pass through. Professor Qiu said in a deep voice.

Although Huang Cheng was flustered, he still nodded, looked at Professor Qiu in the rearview mirror, felt much more relieved, and increased the throttle.

"When will this rain stop?" Yang Jing asked in a whisper with her head down, burying her chin in the pillow.

"Should ......"

"Heavy rainfall of this magnitude, combined with canyon terrain, generally lasts for a long time. Huang Cheng thought he was asking him, but before he could finish speaking, he was interrupted by Professor Qiu, his face was a little nervous and seemed embarrassed, pretending to look ahead and concentrate on driving.

There were four people sitting in the back row, Professor Qiu, Yang Jing, Haichuan and Fang Jingxuan, Professor Qiu leaned against the car window, and Yang Jing was next to him.

"Teacher Haida, can you lean a little closer to the side, you pressed my hand. ”

"Hmm...... Hmmm!" Haichuan reacted.

"And, your hands!"

Haichuan listened to Fang Jingxuan's indifferent tone, glanced at her, when did his hand unconsciously wrap around her waist, and immediately showed his white teeth and smiled at her, looking like I didn't mean to.

"What's going on?" Professor Qiu asked.

"It's the sound of tires slipping. Huang Cheng replied.

"Speed up through this acid rain belt, or the tires will corrode over time. Shang Bin said loudly to Huang Cheng with a walkie-talkie.

After saying that, the throttle was increased, the visibility ahead was very low, and the heavy rain slapped the vehicle with a crisp sound of "popping" steel, like the sound of a person's heartbeat, getting louder and louder, like a struggle before death.

Whenever the car passed through some potholes, Yang Jing was afraid to cover her ears and whisper, so she unconsciously hid from Professor Qiu.
