"Brothers, pack up and get up!"

Lin Yi posted a message in the group, got up by himself, and went to wash first.

Everything was ready, and I went downstairs to the restaurant to pack four breakfasts and take a few seasonal fruits for Goku to snack on.

The morning cold wind in the northwest is like a knife, and a gust of wind can almost blow people through.

What's more, they have now sailed into the thousand-mile Gobi Desert in Tengger.

The car was running against the wind, and it felt like the grit could shatter the front windshield and hit them in the face at any moment.

At the same time, there are many vehicles driving in the opposite direction.

Seeing that they also stuck their heads out to communicate with them:

"Don't go in, it's all banned inside, don't let social vehicles enter, turn around and go."

Wang Qiang greeted them from the driver's seat and continued to drive the car inside.

"What's going on inside?"

"What's the situation? It's blocked, look at these self-media, what are they posting, desert monsters, Yellow River monsters, chainsaw murderers have all come out, if they don't ban it, will they continue to spread rumors? ”

Bai Lu held up her mobile phone and showed the others the popular local videos.

All kinds of bizarre rumors are rampant, and they are not too outrageous.

However, the remarks of one of the vloggers who did not want to show their faces caught Lin Yi's attention.

"Wait, go back and see what the man said."

"Hey, this kind of story that deliberately provokes national sentiment can be listened to for eight paragraphs for a penny at my doorstep, and you might as well listen to me make it up for you."

"Don't squeak! Listen! ”

Wang Qiang twisted his head to the side.

Bai Lu moved her fingers a few times and flipped the video back.

"The location of the Tengger Desert is very special, why do you say that? Because in those days, it was said that there was a small army that crossed through Mongolia, entered from the border of our Ganlong territory, and went around to our rear, trying to give us a front and rear attack.

Just after their troops entered, they caught a huge black sandstorm, and the heavily armed troops lost their way in the desert, and it is said that they did not make it out of Tengger alive. ”

Wang Qiang sneered at the content he made up.

"Little turtle grandson asking for his life? That's it? Borrow a hundred guts for Ya to see if he dares to blow up his hair?

I just said that listening to the eight paragraphs for a penny is considered to be lifting him, and no one wants to listen to this thing, but looking for money. ”

Lin Yi turned around and took Bai Lu's mobile phone and looked through the video content of this so-called "history blogger".

Basically, it's all this kind of groundless rumors, and the words are all ambiguous, and one more sentence will be added at the end, the above content is purely personal collection and sorting, don't take it seriously.

"There are too many people making this kind of pseudo-popular science video now, just watch it lively."

Lin Yi nodded thoughtfully and returned the phone.

Approaching the destination, a cordon was set up around the area early, and the distance from the starting place was expanded by at least three or four hundred meters.

The roads that were blocked by onlookers from all walks of life have been almost cleaned up.

The officers on duty at the checkpoint, under the guidance of Wu Jingshan, checked their identities and let the car go.

All the way into the lake where the crime occurred, a few police cars were parked around, several marching tents were erected, and a temporary headquarters was built.

As soon as a few people got out of the car, a foul smell came to their faces.

The surrounding sand dunes have been covered with pumped sewage, staining the dunes black.

Lao Wei wore a military coat and walked out of the tent.

It looks like I haven't slept all night last night, and I've been staring at the scene.

"There is a major breakthrough Lin consultant, after the pump drained the lake water last night, it detected that there was a channel hidden in the silt, you can take a look."

With that, he took Lin Yi and the others into the tent.

The tent was simply furnished, except for a camp bed and folding tables and chairs, a few maza and two thermoses.

There is a charcoal stove in the middle to keep warm.

"Field operations, the conditions are limited, please forgive me."

After speaking, Lao Wei pulled a maza by himself and asked the technician to bring the laptop.

"This is Technician Liu, we are urgently dispatched from the oil field to help, Xiao Liu, you tell Consultant Lin about the situation."

"Okay, the situation is like this, after our professional equipment probed, in the underground of this lake, found a cavity area, the area is very large, at least about six meters high, the internal space is intricate, there are many passages.

Underneath the area that is now being dredged, we have also found a large metal device, which looks like an exhaust fan judging by its outline, and as for its power source, we have not yet figured out. ”

"Did you get any other information?"

Technician Liu shook his head.

"No, that's all for now."

Lin Yi nodded.

"Old Wei, what do you think here?"

Lao Wei put down the water glass in his hand, stood up and paced in the tent.

"According to Xiao Liu's judgment, this cavity is likely to be artificial, and as for what is going on with this metal device underground, we don't dare to draw conclusions now."

"What do you think?"

Lin Yi set his eyes on Wu Jingshan.

She was like a student whose name was suddenly called by the teacher, and she was a little overwhelmed.

"I think this metal device is probably the mechanism that caused the slashing injuries of those people."

Lin Yi snapped his fingers.

"That's right, the situation at the scene is basically consistent with the information we have before, this was once a hidden soldier cave in the Wei and Jin dynasties, this is a long story, I won't go into too much detail.

As for this metal device, it is actually the ventilation equipment of the underground cave. ”

"The Tibetan Soldier Cave in the Wei and Jin Dynasties? And metal ventilation? ”

It is not difficult to see from the expressions of the other people at the scene that they are full of doubts and curiosity about this result.

"Advisor Lin, take the liberty of interrupting, put aside the matter of this hidden soldier cave for the time being, it is this metal device, if it is really as you said, it is an exhaust fan, then where does its power source come from?"

Lin Yi stretched out his hand and pointed to his feet.

"Natural gas!"

"Natural gas?"

This time, not only Lao Wei and them were confused, but even Technician Liu was stunned.

"Don't be surprised, the wisdom of our ancestors is beyond our imagination. Third, tell me what's going on. ”

'Gotcha. ”

Qian Sheng stood up, quoted from the side, quoted scriptures, and explained the ins and outs to them clearly and clearly.

"As early as the Han Dynasty, it was recorded in the Book of Han that 'the fire well of the Ancestral Heaven Fengyuan was in Hongmen', Hongmen County, set up in the Han Dynasty, belonged to Xihe County, and was in Shenmu City, north of today's Sanqin.

In the Northern Wei Dynasty, Li Daoyuan, the author of "Notes on the Book of Water", also mentioned natural gas in his works.

If you want to use it, at the end of the Eastern Han Dynasty, Sichuan has begun to use the 'fire well' to cook salt. ”

After listening to his explanation, everyone suddenly realized.

The Tengger Desert is rich in natural gas reserves, and the kind of long-burning natural gas wells often occur in the desert.

It's no surprise that a natural gas-powered exhaust fan appears here. (End of chapter)
