In a hospital in southern Qinghai, in the city of Golmud, Yang Jian was sitting on a hospital bed, stroking the broken sword in his arms. The sword is two feet four inches long, the hilt is like finely carved white jade, but the sword body is red like blood, with dark gold dragon patterns hidden in it, and the brilliance is contained, like a fine work of art. It's a pity that the tip of the sword broke for some reason, and only jagged fractures remained.

In front of Yang Jian, there are several dilapidated ancient books and a few old newspapers, the most eye-catching, or a copy of the "Shengjing Times" on August 12, 1934, the most eye-catching is the "Jiaolong dried up" four big characters, and then, it recounts the "Yingkou Falling Dragon" incident that caused a sensation in the country at that time, and there is also a photo of the keel next to it.

"Don't look at that, you can find a lot of news about the falling dragon in Yingkou on the Internet, look at this notebook, it's definitely the only one." Wang Tian, who was in another bed in the ward, casually threw an ancient book to Yang Jian. Wang Tian was born in a wealthy family, and getting these precious documents was just a matter of words to him.

"On the ninth day of September in the ninth year of Jiaqing, Yu lived in Kunlun Yuxu and was sleeping. Hearing the sound of the cow, he set out to inspect it, but he was shocked, it was really a dragon chanting......" Seeing this, Yang Jian fell into deep thought.

It all started a week ago.

With the end of the college entrance examination, Yang Jian's time has also become freer, and he planned to find a temporary job to earn some living expenses. But at this time, Wang Tian found Yang Jian, who was an orphan. Originally, there was a gap between the two. It is impossible to cross paths in this life. But the shared hobbies of exploration and the study of anecdotes make them good brothers.

"I have a relative who is in the survey team, and he heard the dragon's chant when he was inspecting the Death Valley in Kunlun Mountain, and the news is absolutely true and reliable." For such a reason, Yang Jian followed the expedition team formed by Wang Tian to the legendary Kunlun Mountain Death Valley. And, of course, there are hidden conditions – eat and drink for free.

Everyone galloped all the way, and with the support of Wang Tian's strong equipment, it only took five days to rush to the Death Valley of Kunlun Mountain. "Isn't Death Valley generally closed to people?" Yang Jian was a little scared, after all, Death Valley was famous. Wang Tian smiled, "The order is wrong, it's Death Valley that doesn't allow ordinary people to enter, come on, now I'll give you a formal introduction, our team." Wang Tian proudly pointed to the four people behind him and introduced, "Old thief, born in tomb robbery, experienced. The middle-aged old thief frowned slightly when he heard Wang Tian say so loudly.

"Army, you know, my bodyguard, retired soldier. These are the two brothers Zhang Yu and Zhang Bi, both geological surveyors, and my father spent a lot of money to invite them. After listening to Wang Tian's introduction, Yang Jian was a little shocked, how much his parents love him, in order to play with him, even the tomb robbers were invited. Seriously, Yang Jian didn't think that this expedition would make any discoveries, after all, dragons were too ethereal, but his inner curiosity and the young man's playfulness prompted him to come here.

"Let's go, be careful, you guys follow me." Zhang Yu and Zhang Bi, two surveyors, walked in front and explored the way for everyone, although a few people came here with the mentality of playing with Wang Tianda, but they didn't dare to take it lightly, after all, this is Kunlun Mountain Death Valley, one of the world's five major death valleys.

As he continued to advance, Yang Jian saw the bones of many animals, and in the evening, everyone had gone a lot deeper. "Let's set up camp here today." Zhang Yu said, putting down the hiking backpack behind him and starting to build a special tent, which has no metal components such as the bracket. Because of the abnormal magnetic field of Death Valley, it can produce air discharge with the electric charges in the clouds, making Death Valley a mine-rich area, and many people and animals have been killed by thunder.

"We won't just come here for a tour, we haven't found anything in a day, if that's the case, I might as well go to Sanya, I heard that the beauties there are very open." Wang Tian walked to the side as he spoke, preparing to set up a tent. "Oops!" Suddenly, Wang Tian screamed and fell to the ground. Everyone was shocked, and they all stopped their work and ran towards Wang Tian. "It's okay." Yang Jian asked with concern. "It's fine, just a fall." Wang Tian got up, and when he looked back, it was actually a skeleton half-hidden in the yellow sand.

"It's unlucky." Wang Tian scolded secretly, fortunately, there were a lot of bones of the animals he saw today, otherwise he would not be scared to death when he suddenly saw such a skeleton.

"Strange, there is not a single skeleton in this square circle, why is there a skeleton here?" The old thief said with a frown. Yang Jian realized that this place was a little strangely clean, and the bones of animals could be seen more or less along the way before, but now when he looked at it, he couldn't see any of them.

Zhang Bi pondered for a while and said, "The plan has changed, now we have to get out of here, is it forward or backward?" "Stand back, after all, I don't know how long it will take to leave this area, and who remembers the last time they saw animal corpses?" Zhang Yu quickly put away the tent and walked in the direction he came.

"About an hour." The habit of robbing tombs for many years has made the old thief habitually remember the road conditions when he came. "Alright, let's hurry back, we should be able to get out of this place before dark." The two brothers of the Zhang family turned around and left, without hesitation at all.

As for Yang Jian and Wang Tian, they were also scared because of the current situation: "Brother Zhang, what is the situation?" For the wealthy employer, Zhang Yu patiently explained: "The disappearance of the corpse may be related to the permafrost of this generation, and the permafrost turns into a swamp in the summer to hide the corpse, so we can't see the corpse." If we spend the night here, after a night of rain and dew, the soil may become soft, and then it will be troublesome to sink in, and there is also a dark river found under the swamp in the depths of Death Valley, once you step into it, you will be immediately sent into the bottomless abyss by the great suction force of the dark river. ”

Wang Tian couldn't help but shudder when he heard this, only now did he know how dangerous the place he came from was. Although on the way here, he and Yang Jian made up the knowledge of Kunlun Mountain, but with the virtue of the two of them, the knowledge of myths and legends is naturally supplemented.

For some reason, Yang Jian felt a little uneasy in his heart, maybe everyone would feel uneasy in this oppressive environment.

......The weather in Death Valley was also unpredictable, and half an hour later, a thunderstorm suddenly hit without warning. Everyone was a little anxious, so they wanted to run forward. "Don't run, that will provoke thunder and lightning, everyone just lower their bodies and walk normally." Zhang Bi stopped everyone in time, but everyone was even more anxious, and they wanted to leave quickly but could only walk slowly.

After a while, the rain was pouring down on the ground. "No, there's a big rock in front, let's go and hide in the back." After a day's trek, Wang Tian, who was usually pampered, was already physically and mentally exhausted, and although everyone was unwilling, they could only accompany Wang Tian to hide from the rain behind the boulder.

Although the boulder can't completely cover everyone, it can still block some of the rain. Everyone felt that the pressure on their bodies was a lot less, but they didn't dare to stay longer. "When the rain is a little lighter, let's continue on our way." Zhang Yu said with a frown. The only person who can still calm down is the Veterans Army.

"I feel like we're sinking." Yang Jian has been very sensitive to the subtle changes in the environment around him since he was a child, and now he feels that the ground is sinking, and he doesn't know if it's an illusion, so he said it and asked everyone. "I feel that way, too." The old thief looked at Yang Jian in surprise, a little curious about Yang Jian's perception ability, after all, even he couldn't feel what Yang Jian didn't say.

"Run." Zhang Bi heard the conversation between the two, and regardless of the danger of being struck by lightning, he ran away. Before everyone could react, they heard a "boom", followed by the feeling that the sky was spinning. Yang Jian felt as if he had fallen into a tumbling river of mud, not only his body was uncontrollable, but his mouth and nose were also filled with mud, the feeling of suffocation continued to impact his brain, and the fear of death began to spread in Yang Jian's mind, and then, he lost consciousness......
