Xia Ruobing was a little annoyed, and slapped the flashlight a few times, but it had no effect. Wang Xingguo took out two spare batteries from the first-aid kit and said, "Don't shoot, it's out of power." ”

"How long can we hold out." Xia Ruobing asked worriedly, the consumption of this battery greatly exceeded her expectations.

"We've been almost 20 hours since we started the operation, and the break in between adds up to about eight hours...... It's pretty good that the battery lasts so long. Wang Xingguo replied lightly.

"In other words, we can hold on for two 20 ......hours at most," Xia Ruobing said worriedly, Wang Xingguo only prepared a set of spare batteries, and he didn't prepare at all, even if he saved more, he could only last for two more days at most.

"Almost...... But I think there's plenty of time. Wang Xingguo shrugged his shoulders, this battery is really good, it has been used for almost 12 hours in a row under the alternation of low light and strong light, it seems that I will have to buy this brand next time.

"Is it enough?" Xia Ruobing asked worriedly.

"Enough ......" Wang Xingguo smiled and pointed to the end of the passage, after the flashlight went black, there was a faint light in the distance.

"There is light! There really is light! Xia Ruobing became excited.

"Let's go, where there is light, there is an exit." Wang Xingguo put the bag on his back, and the backpack strap pressed the wound on his shoulder, which made him gasp in pain.

"Are you alright?" Xia Ruobing asked with concern.

"It's okay, let's go." Wang Xingguo adjusted the position of the backpack strap to prevent it from pressing the wound, thought about it, wrapped the teeth in his hand and the cow mandible, and let Xia Ruobing stuff it into the backpack.

"Target, ahead!" Xia Ruobing thought that she would be able to go out soon, and she was in a cheerful mood, so she walked in front of Wang Xingguo first, and climbed up the slope despite stepping on the pile of teeth under her feet.

"Xia Ruobing, be careful of slipping." Wang Xingguo reminded.

"Don't worry, keep up." As Xia Ruobing spoke, he walked ten meters away, and Wang Xingguo hurriedly followed.

……

"Wang Xingguo, what do you want to do when you go out?" Xia Ruobing asked.

"Hmm...... Scout the environment. Wang Xingguo began to lose his mind again, he always felt that something was wrong, but he couldn't say it.

His grasp of the direction is still very good, although he has gone around a lot of circles, but Wang Xingguo is sure that his general direction is to go north, according to the distance, at this time they should be halfway up the coffin mountain, Wang Xingguo faintly felt that he was close to the truth, those unfinished tombs and passages, the stone carvings with eyes carved in the stone room, the well-preserved tomb of the feather, and the cinnabar in the tomb, the corpses that disappeared from the ghost gate, and the countless bones in this cave, all prove that there is a special relationship between them.

From the analysis of the existing situation, only the handling can explain how the corpse left the ghost gate, since it was carried into the coffin mountain, there must be a carrying channel, it can't be a ghost to carry the corpse, right? That must be a creature, but ...... What is it exactly?

In short, Wang Xingguo searched every inch and corner from his profound knowledge, but did not find any information that could correspond.

"Xia Ruobing, the sun burial of the Loulan people, is there really no other form?" Wang Xingguo asked, he seemed to have found a connection in the tombs and passages, as well as in the caves where bones had accumulated.

"According to the available information, the Loulan people did not have a solar burial system in the cave." Xia Ruobing thought about it and said definitely.

"Could it be that because they migrated here, there is no desert, and they have changed?" Wang Xingguo asked, after all, customs will continue to change with the course of history, and it is possible that 2,000 years have passed.

"But we don't have evidence, although I now think that this is the Loulan people, the descendants of the wizard lineage, but to make the academic community admit it, I must come up with effective evidence and form a chain of evidence!"

Xia Ruobing is a little helpless, intuition is sometimes right, but she can't write her intuition into the paper as evidence, everything else that is related to Loulan here is speculation, and Lu Wen was used by many countries in the Western Regions in ancient times, and it slowly disappeared in the long river of history around the Wei and Jin dynasties in 1500.

Wang Xingguo stepped on those deep or shallow teeth and bones, and there was only the sound of them stepping on them in the cave, these bones could not have been formed in a short time, some places were piled up to a meter thick, and the passage was very wide, and in some places it was even as high as ten meters, Wang Xingguo thought about things, what was it, moved these corpses here, and then ate them to almost nothing?

The light is getting stronger and stronger, but it seems that the accumulation of bones is getting thicker and thicker, Wang Xingguo is puzzled, but at least he knows a little now, since there is a transportation channel, then he will definitely be able to get out, which is the best news for Wang Xingguo.

Xia Ruobing walked and walked, feeling that the terrain was changing, the slope was very steep, almost 45 degrees, and the slope was not the main factor that caused trouble, mainly because of the scattered ...... in this big passage Or that there are too many teeth and bones piled up, which has a serious impact on the climb, and it is often difficult to climb up three steps and slide down two steps, but what surprises Xia Ruobing is that the more he climbs, the more spacious the space becomes, as if he is climbing an upside-down gourd, the brisk setting off just now has become difficult, and the two of them have climbed for more than half an hour, and they don't seem to have climbed far.

For so many teeth and bones, Xia Ruobing didn't think much about it at this time, she just wanted to get out quickly, she didn't want to stay longer for a second here, she didn't want to be a part of these bones, the desire to survive made her very focused, and even ignored anything else.

Xia Ruobing finally climbed to the most difficult section with a snort, but looking around, there were more teeth and bones piled up here, Xia Ruobing raised his eyes again and shouted: "Wang Xingguo ......"

"What's wrong?" Wang Xingguo climbed the steps with his hands and feet, and because of the injury on his shoulder, he had to constantly adjust the position of the harness, which caused him to slow down.

Xia Ruobing sat down and hugged her knees, this was a sign of her discouragement, Wang Xingguo climbed up and stood beside him, there was no need for a flashlight at this time, but the exit was not what she imagined.

This is a huge hall, a beam of light obliquely shines in, just reflected at the mouth of the passage, on the other side of the abyss can faintly see the light, but the place where this light enters is located at the top of the hall, dozens of meters above the ground, and the ground is like a huge pot, the "pot" contains white teeth and bones......

The exit was there, and the sunlight was shining through there, but they couldn't go up! Wang Xingguo also felt a breath of qi leaking out of his body, and sat on the ground, and a wave of irritability surged from his heart.

After all the hard work to get here, the exit is within reach but you can't get out, and there's nothing more demoralizing than this.

"Xia Ruobing......" Wang Xingguo sighed and called softly.

"Huh?" Xia Ruobing responded like a mosquito humming.

"Rest, we can figure it out." Wang Xingguo didn't know if this sentence was a consolation.

"Hehe......" Xia Ruobing's reaction made Wang Xingguo a little strange, it seemed that there were already signs of indifference, which was a taboo in survival, once a person entered the stage of indifference, it was tantamount to giving up the last hope of survival.

Wang Xingguo took a few deep breaths, suppressing the irritability in his heart, he had to stay calm now, absolutely calm, he carefully recalled everything that happened, he confirmed that there would definitely be an exit, he had to find the exit, but this exit seemed to be playing hide and seek with himself.

Wang Xingguo took out the route map and sorted out all the processes again, these bones must have been brought in in some form, there are ramps and rugged paths along the way, and a corpse that can't move can actually get here, there is no reason why a big living person will be trapped to death.

Xia Ruobing's mood fell to the lowest point again, all his efforts were in vain, he saw Wang Xingguo take out the route map, and asked faintly: "Wang Xingguo, do you know that we will die?" ”

Wang Xingguo was stunned for a moment, thought about it and said slowly: "My intuition tells me that the probability of survival is very slim. ”

"Alas......" Xia Ruobing sighed in disappointment.

"But we still have a choice!" Wang Xingguo said slowly, his tone firm, "At least we are alive now." ”

"I'm scared." Xia Ruobing said weakly, getting closer to Wang Xingguo.

"I'm scared too." Wang Xingguo smiled and leaned towards her, giving her a support, she would feel better.

"Hug me." Xia Ruobing wrapped her hand around Wang Xingguo's waist, and Wang Xingguo gently hugged her shoulders and let her lean on his broad chest.

"Your heart is beating so powerfully." Xia Ruobing's ears were close to Wang Xingguo's heart, and she heard it beating in her chest.

"You can rest for a while." Wang Xingguo patted her gently.

"Hmm." Xia Ruobing closed her eyes obediently, and said in a low voice, "Wang Xingguo, if I die first, you have to help me wash my face and put it in the sun, and I want to keep it beautiful to go to see my parents." ”

"No, I'll take you out...... That's right! Sunlight! Wang Xingguo suddenly became excited, "Xia Ruobing, we have been saved, there is sunshine!" ”

"You're lying to me again." Xia Ruobing shook her head.

"Where there is sunshine, there is direction! You look at the map, and the route map! ”

Xia Ruobing sat up, Wang Xingguo took out the map and sketched lines on it: "We have ignored a few places, if the coffin mountain and the surrounding villages are a huge sun burial, then this is a small sun burial!" ”

Xia Ruobing smiled bitterly, the sun burial is just a guess, if not, all inferences will be overturned.

"Do all funeral customs have special rules?" Wang Xingguo asked rhetorically.

"The coffin mountain is in the middle, the big funnel is exactly a circle, the south is the Ghost Gate Pass, and the north of it is almost equidistant, is Zhixin Village, the west is Chengzi Village, the east is Liming Village, and then expands to the periphery, there are four villages in the northeast, northwest, southeast and southwest, including Shanguo Village, they are distributed in concentric circles, and the orientation is very positive, this is certainly not a coincidence!" Wang Xingguo drew the lines and handed them to Xia Ruobing.

Xia Ruobing looked at it carefully, it was indeed like what Wang Xingguo said, but how did this help in finding the way?

"Look at the route map again! We came in from the ghost gate, and fell into here in the south of the coffin mountain, these are the routes and tombs, stone chambers, have you found them? They're also around the current boneyard! Wang Xingguo said excitedly, "So the coffin mountain is a huge sun burial, and in the coffin mountain, there is a small sun burial, those tombs are also dug according to the shape of the sun burial, they put death in the center, Xia Ruobing, there will definitely be a way out here!" Let's start by setting the direction! ”

Xia Ruobing looked at the route map drawn by Wang Xingguo, if what Wang Xingguo said was correct, this is the center of death, those tombs and stone chambers are indeed semi-around this death zone, there are indeed radial passages between each stone chamber, which should be connected in theory, the tomb of Yu is in the northeast, a little far away, and the stone chamber with the beetle carved with eyes is not far from here on the map.

"But the damage here is very serious...... Xia Ruobing is still a little worried, even if there is a passage to go out theoretically, what if it is blocked.

"Xia Ruobing! At least we still have a choice! We're alive! Wang Xingguo shook Xia Ruobing's hand vigorously, "I'll take you out!" Believe me. ”

"That'...... Where do we start? Xia Ruobing asked.

This was all at once asked Wang Xingguo, he only had a broken route map in hand, many passages were damaged, and many were not completed at all, even if he mustered up more courage at this time, he could not point out a way out.

"Xia Ruobing, when the people of Loulan are buried with the sun, which way is the head bent to bury?" Wang Xingguo looked up at the sunlight that was slanting in and asked.

"Most of the heads are facing north, what's wrong?"

"Respect the north, let's go north!" Wang Xingguo said with certainty.
