Wang Xingguo also heard the echo, was stunned for a moment, instinctively pressed his hand on the survival knife on his waist, opened the scabbard, held his breath, and after a while, the sound disappeared, and the cave was quiet.

Wang Xingguo closed the scabbard: "Xia Ruobing, if you want to live, I will make three chapters with you!" ”

Perhaps frightened by the strange sound just now, Xia Ruobing finally calmed down at this time and looked at Wang Xingguo steadily.

"First, don't run around alone! Second, follow the command! Third, give me the focus to survive! ”

"But......" Xia Ruobing turned his head to look at the wall.

"No, but! From now on, I'll let you go east and you can't go west, and you'll be asked to chase dogs and not chickens, understand? Wang Xingguo interrupted her.

"This is ......," Xia Ruobing still wanted to argue.

"Do you know where we are now, Sherpa and their life and death are still uncertain, we don't know where the way out is, do you want to disappear here like your parents?" Wang Xingguo's voice became louder again, and he couldn't give Xia Ruobing any chance to fantasize at this time.

As soon as the words fell, there were bursts of "click" sounds on the side of the passage, the sound reflected in the cave wall, the feeling became denser and denser, and a trace of fear climbed into Xia Ruobing's heart.

"Okay," Xia Ruobing's heart was furious, and she couldn't help but take two steps towards Wang Xingguo's side.

Wang Xingguo distinguished the voice, felt that it would not pose a threat for the time being, glanced back at Xia Ruobing, and said very seriously: "Xia Ruobing, you must keep your promises!" ”

Darkness, can't find a way out, can't even find a direction, there is a serious shortage of food and water, no rescue, any of these can be regarded as a very serious problem in outdoor sports, so many unfavorable factors are superimposed, Wang Xingguo has to think about how to survive, but Xia Ruobing is not a professional expedition member, when she saw cinnabar, the instinct to pursue the truth made him ignore the most realistic problems.

When Xia Ruobing was pulled back to reality, she could feel the pressure gradually accumulating in her heart, she didn't know when she would collapse, and now her only reliance was Wang Xingguo, seeing Wang Xingguo walking into another passage, Xia Ruobing hurriedly followed.

Wang Xingguo didn't say a word all the way, in the already oppressive and dark underground, Xia Ruobing felt even more depressed, and she didn't bother to explore the few mottled murals in the passage, she followed closely behind Wang Xingguo.

"Wang Xingguo, are you angry?" The depression made Xia Ruobing feel that she should say something.

"I'm angry, I'm angry, but being angry won't solve the problem." Wang Xingguo stopped at the fork in the road, picked up a flashlight and shone it left and right, "Go this way"

Xia Ruobing dared to raise an objection and followed Wang Xingguo into the fork in the road.

"Could it really be that the Loulan wizard clan dug this place as their mausoleum?" Xia Ruobing asked.

"Maybe, why don't we find a dead man and ask?" Wang Xingguo's attention was not on Loulan or the mausoleum at all, he was now trying to survive.

After a little further walking, the passage was blocked by collapsed stones and earth.

"Dead end, turn back." Wang Xingguo didn't delay for a second, turned his head and walked back. This reaction speed surprised Xia Ruobing, and he didn't seem to have to think about it. Turning back to the fork in the road just now, and turning to another passage that he had not walked through, Wang Xingguo was silent again.

"Wang Xingguo, can you say something?" In the monotonous light, only the sound of boring footsteps was heard, and Xia Ruobing felt that the fear in her heart was getting bigger and bigger.

"I wonder how long the battery will last." Wang Xingguo explained.

"How long do our batteries last?" Xia Ruobing asked, in the cave, there is no light source, it is fatal.

"From turning on the flashlight until now, it has been about two hours, and there is half an hour in the middle to look at the murals, theoretically, my flashlight can continue to illuminate for 15 hours in low light, and about 10 hours when playing 6, and there are two spare batteries, and you also have a flashlight, a headlamp, hmm...... At most, our battery lasts 40 hours......"

"A day and a half?!" Xia Ruobing exclaimed, a day and a half is not too long for survival.

"That's right, so I advise you not to waste another second, speed up your actions, and don't do unnecessary consumption." Wang Xingguo said, at this time, the passage was almost to the end, he saw a fork in the left road, Xia Ruobing was confused by Wang Xingguo's calculations, there were so many batteries in her estimate, which could support at least three days, and she didn't notice a fork in the road for a while.

"Left, Xia Ruobing, what do you want......" Wang Xingguo looked at her and walked straight forward and reminded.

"Oh......" Xia Ruobing's heart sank, maybe the situation was worse than he imagined.

"Wang Xingguo, I'm sorry......" Xia Ruobing said in a low voice.

"Hmm." Wang Xingguo's answer was absent-minded, he used a flashlight to shine around, this passage is quite spacious, and there are still some traces left by cinnabar paintings on it.

Wang Xingguo reached out and touched the wall of the cave, and a piece of cinnabar paint fell off and stuck on his hand.

"Don't touch it!" Xia Ruobing saw it and screamed in distress, this is the destruction of cultural relics!

"Who's going to paint these things here?" Wang Xingguo looked at the lump of paint in front of him, which could no longer distinguish the pattern.

"If my parents are right, this is the mausoleum of the Loulan wizard."

"But what about corpses? What about coffins? Wang Xingguo asked again.

"This ......" How could Xia Ruobing answer, this archaeological research should pay attention to the chain of evidence, even if he thinks it is the mausoleum of the Loulan wizard, just with these blurred murals and this artificially excavated underground labyrinth, of course it will not work.

"It's been abandoned for a long time, no one has ever come again, and if it's a cemetery, why hasn't anyone come again?" Wang Xingguo asked again.

"It could be ...... for other reasons"

"It's taken so much effort, so you don't want it?" Wang Xingguo thought for a while, "What about those dead people?" What about the bones? ”

Wang Xingguo spoke, his eyes crossed Xia Ruobing, in order to save electricity, Wang Xingguo only turned on the weak light gear, in the dark, this light is enough, but the darkness is too far away to swallow the light, and the far end of the light looks very dim, Wang Xingguo seems to see a fork at the end of the light, and focuses his attention on the past.

"Wang Xingguo, have you ever seen a dead person?" Xia Ruobing followed his topic and suddenly thought of this.

"Hmm...... Seen ...... Also memorized. Wang Xingguo wanted to wait for the fork in the road, how to go, and his mouth was a little distracted.

"You've carried a dead man?!" Xia Ruobing was shocked, "When?" ”

"When I was a soldier, one of my comrades-in-arms died, and I carried it back." Wang Xingguo said, "Do you see the fork in the road ahead?" ”

"Well, I see...... Wang Xingguo, aren't you afraid? ”

"I'm afraid...... But I can't leave him behind, he deserves a decent funeral. Wang Xingguo said.

"A decent funeral?" Xia Ruobing seemed to think of something, but then he was denied by himself, if this is a wizard's cemetery, it is undoubtedly very decent for a wizard to dig such a grand and complex cemetery underground, but the people in those villages outside the coffin mountain are the descendants of wizards, and they can carry the corpse to the ghost gate and let it go, which cannot be said to be decent in any case.

"Yes, that's what I thought, we don't know if we will come back alive from the next battle, and we don't even know where we will die and how we will die, but at least we can return to our hometown, so we agreed that no matter who died, the one who was alive would bring the dead back, huh...... Left or right? As Wang Xingguo spoke, he had reached a fork in the road, which seemed to be a slightly widened place in the passage, and two more passages were opened here, and he shone a flashlight on the left and then on the right, asking Xia Ruobing's opinion.

"Uh...... I don't know. Xia Ruobing was still thinking about the mausoleum and the ghost gate, and she was a little distracted.

"We're in the northern hemisphere, and the monsoon is counterclockwise, so let's go to the right." Wang Xingguo illuminated the fork on the right with a flashlight, picked up a stone casually, drew an arrow on the edge of the cave wall, and then wrote the number 1 to make a road sign.

After walking a little further, a stone chamber appeared in front of them, but most of this stone chamber had collapsed, and there was no other way out in it, so the two had to retreat back and find another path to try.

The successive failures made Xia Ruobing very discouraged, she felt more and more tired, and her injured knee was also aching.
