Patches of salt lakes were left behind by Harvard H9, and under the clear night sky, there were patches of turquoise sky mirrors.

Every time the road forks, Luoyang will ask Batugar to stop the car, then get out of the car to observe the tire tracks, grab a handful of saline-alkali soil to sniff, confirm the direction and then get in the car and let Batugar drive in the direction he indicated.

Once, Batugar couldn't help but ask: "Brother Luo, is your nose so smart?" ”

"Okay." Luoyang has no superfluous explanations.

"When I was a child, I had a sheepdog with a very smart nose, and if there was a wolf to catch a sheep, it could smell the wolf from a few hundred meters away, but even if it was such a powerful sheepdog, it couldn't smell anything from the mud marks left by the tires," Batugar said. ”

Luoyang didn't know how to answer this.

"Well, I don't mean anything else, it's just ......" Batugar didn't know how to explain it.

"Brother Batu, how far can this car go?" Luoyang changed the subject.

Batugar said: "Don't worry, when I refueled, I used two barrels of oil in a bucket for backup, and I can drive hundreds of kilometers." In addition, I also bought some food at the supermarket at the gas station, including bread, ham and sausage, do you want to eat some? ”

"No thanks." Luoyang is in the mood to eat.

Harvard H9 drove dozens of kilometers forward, and there was no road. In front is a potholed saline land, and in the distance is a series of rolling hills, some a few meters high, some tens or hundreds of meters high, and everywhere you can see the ravines and steep rock walls of the rushing water.

The traces of the two tires extended forward and entered the Yadan landform.

The Harvard H9 cautiously came between the two hills, and drove forward for dozens of meters, and a Toyota off-road vehicle appeared under a cliff, the right rear wheel was deflated, and the body was obviously tilted.

Batugar said excitedly: "Brother Luo is amazing, he really caught up!" ”

"Just stop here, I'll take a look." Luoyang said.

Batugar stopped the car, he actually wanted to stop, this is not like the saline ground, salt crystals will make the ground hard, but the ground here is sandy, if you are not careful, you will get stuck in the car.

Luoyang got out of the car and walked quickly to the side of the Toyota off-road vehicle.

There was no one in the car anymore, and there was a series of footprints stretching forward in front of the front of the car.

The windows of the cab were not closed tightly, leaving a slit. Luoyang leaned in front of the gap and sniffed, and quickly locked on to Ye Zi's scent, her smell brought him a little intimate and familiar. The smell of the other two people is also locked, which matches the smell on the clothes, one is the smell of the driver Deng Cong, and the other is the smell of the assistant Zhong Lin.

Luoyang came to the front of the car and carefully observed the footprints on the sand.

Luoyang took a closer look, it was the footprints of three people mixed together, the larger and darker ones should be the footprints of the driver Deng Cong, and the shallower and smaller ones were the footprints of Ye Zi and her assistant Zhong Lin.

Luoyang lay on the sand, put his nose on the footprints and sniffed. Under the super-sensing state of the ancestral witch spirit, the faint smell of sand became as strong as the fried sauce. Soon, a trace of a familiar smell was "extracted", it was Ye Zi's smell.

confirmed, not only Ye Zi's traces, but also the nature of this matter.

Luoyang stood up, took out his mobile phone and looked at it, but the phone had no signal at all.

Batugar walked over: "Brother Luo, I just looked, there is no signal here, and I can't make a call." ”

Luoyang said: "Brother Batu, I will share a little of the water and food in the car, you stay here and wait for me, and if I haven't come back after 24 hours, you can make this call." ”

He opened the contact and found Hu Bufei's phone number.

"I can't remember, I'll take a picture." Batugar took out his mobile phone to take a picture and said, "I made this call, what should I say?" ”

Luoyang said: "You told him that Luoyang is in the desert of the vast cliffs of Qingdi, Ye Zi is in danger, you ask him to come over and save people quickly." ”

"Then I have to go back and get a signal to call, how long am I waiting for you here?" Batugar asked.

Luoyang thought for a while: "20 hours, if I haven't come back by then, you can leave here to make this call and tell him what I just told you." ”

Batugar stepped forward and patted Luoyang on the shoulder, and admonished: "Brother Luo, you must not go too far, it is fatal to get lost in the desert." Moreover, this is a saline-alkali desert, and there are large and small karst caves underground, and if you fall down, you may not be able to find the corpse. ”

"Caves?" Luoyang suddenly became worried, as far as he was concerned, he would never get lost, wherever he walked, he could return the same way with the smell. But if Ye Zi accidentally fell into some karst cave, he lost Ye Zi's scent, and he couldn't find Ye Zi.

"There is salt under the saline desert, and when the temperature is high, it melts, and the salt turns into salt water and flows away, leaving a karst cave underground, but people can't see it on the ground, so you must be careful." Batugar explained.

Luo Yang nodded: "I know, thank you." ”

A moment later, Luoyang was on his way with a worn-out canvas bag on his back.

The bag was Batugar's military satchel with tools, which contained six bags of bread, four bottles of mineral water, seven or eight ham sausages and a flashlight. I was in a hurry when I came, and I didn't ask Batu Gar to buy more water and food, but I could only make do with it in this place.

The footprint stretches forward.

Luoyang didn't destroy those footprints, he walked beside the footprints all the way, and left a clear line of footprints on the sand. If Hu Bufei or the local police chase after him, they can also get important information from the footprints on the ground.

More than ten kilometers passed, the hill grew bigger and higher, the sedimentary rock from the ancient water flow was exposed to the air, and in some places you could even see shells and fish fossils. There is not a single green plant as far as the eye can see, only yellow sand, brown rocks, and there is not the slightest sound around, giving people the feeling of being in an alien planet.

The ground became harder and harder, and the cyan and black Gobi stones became more and more numerous, and the footprints on the ground became lighter and fainter, and finally disappeared.

Luoyang stopped at the last footprint.

In front of it is a canyon, on both sides of which are hundreds of meters high Yadan Mountain, most of the mountain is buried by yellow sand, only a section of the mountain is exposed. But when I stood at the mouth of the canyon, I saw a 90-degree vertical cliff, the sunlight was blocked out, and the light in the canyon was dim, and there was no end in sight.

However, on the left side of the canyon is a piece of Gobi, and there are no footprints, but it is possible for people to bypass the canyon and go to the left.

Luoyang lay on the ground and sniffed around the rocks with his nose. Fortunately, there was no wind, and the smell remaining on the rocky ground was very faint, but in the super sensing state of the ancestral witch spirit, he could barely catch the smell remaining in the stone crevices.

He almost crawled to the entrance of the canyon, but it was here, and his mood became more and more solemn.
