It was only when they entered the cave and were temporarily safe that an argument arose, no doubt over the question of the whereabouts of the tool that could record geology.

"That thing conducts electricity, and now the lightning is thundering, and you can't take him out at all, you have to throw it away. Gu Xingshen felt that in this situation, it would be a burden to take this thing with him, so he wanted Jin Jianguo to throw away this tool.

"This tool is very important, with it, the country can save a lot of things, and even a lot of aspects of geological research, the level of the country's geologists will also be raised to a higher level, it is impossible to throw it away. But Jin Jianguo felt that Gu Xingshen must be joking, such an important thing, he had to protect it even if he didn't want to die, how could he be willing to throw it away?

"But now we can't even get out of this place, what's the use of keeping it, if we throw our lives here, and we can't hand it over to the state, he's still useless. And Gu Xingshen felt that Jin Jianguo couldn't drill the horns at this time, and even lost his life, what kind of country did he talk about.

"You don't have to say any more, I can't have thrown it away anyway. When Jin Jianguo heard him talking about himself again, he let himself throw away the tool and hugged the tool in his arms tighter.

Seeing that Gu Xingshen wanted to say something more, he walked directly towards the entrance of the cave with his things.

Although Wu Haolin also felt that the tool was taken by Jin Jianguo, it would only drag Jin Jianguo down, but since it was what Jin Jianguo wanted to do, he didn't have anything to do.

At this time, seeing Jin Jianguo walking towards the outside of the cave, Wu Haolin also hurriedly followed, for fear that he would have some accidents, after all, what he was holding in his arms was equivalent to a time, time, explosion, and bomb.

It's just that before Jin Jianguo walked out of the hole, a bolt of lightning struck down and fell on the ground in front of him, Jin Jianguo was suddenly frightened and took a step back and was stunned in place.

Wu Haolin pulled him back into the cave, but before he could react, he looked at Wu Haolin in a daze, speechless for a long time.

The people in the cave also felt that they had palpitations, if they didn't run in time just now, and they were still outside, the consequences would be unimaginable, and it was impossible to get out at this time, so they could only look inside the cave to see if there was a way to other places.

Jin Jianguo was silent, let Wu Haolin pull him back, and followed the people in the cave forward, but he still didn't let go of the tool that could record geology.

Gu Xingshen could only shake his head like him, Wu Haolin, he didn't worry about what he was worried about, in other words, Jin Jianguo hugged him so tightly, Cheng Qingxue wouldn't think about getting this tool, no matter who the two of them were, one of them had to bring this thing back anyway.

The more you go inside, the darker it becomes, and gradually the naked eye can no longer tell where it is, where the road is the wall, Cheng Qingxue felt out a fire fold from the package, and wanted to light it, but the flame just came out, and there was a "bang" sound not far away.

"What's going on?

Is there something strange in this cave?Or is there something wrong with this cave?" Listening to the sudden sound, and the slight shaking under his feet, Gu Xingshen instantly remembered a mine collapse that he had experienced with Cheng Qingxue before, grabbed Cheng Qingxue's hand, and wanted to pull her out.

Cheng Qingxue hurriedly grabbed him: "This is not a cave collapse, there should be some special minerals in this cave." ”

The moment she heard the slight explosion just now, Cheng Qingxue also reacted in the same way as Gu Xingshen, but she quickly got up with some minerals, which would explode when she encountered an open flame.

If he was not mistaken, the cave must have been mined before, and there was a residue of magnesium in it.

Magnesium is a mineral that will explode when it encounters an open flame, so the situation just now is purely normal, as long as the amount of magnesium in it is not very large, then they don't need to worry about it for the time being.

It's just that Cheng Qingxue understands these things in her heart, but others don't know, so she suddenly remembered that none of them had been exposed to these things.

Looking at the confused eyes of the others, Cheng Qingxue could only answer to them: "This should be a mine before, after being mined, there are some residues of magnesium, a metal substance, and this substance will explode when it encounters an open flame, as long as there is not much left in it, we don't need to worry." ”

It was only after listening to his explanation that I was relieved, but I was just worried about how much of this substance was in it, and according to the current situation, there was no problem, so I temporarily put out the fire and groped forward.

I don't know how long I walked forward, Gu Xingshen only felt that his feet suddenly slipped, and he subconsciously stretched out his hand to grab the thing beside him.

He couldn't see anything in the darkness, but he felt like he had grabbed someone's hand, and he was able to stabilize his body before letting go.

"Stop, don't go any further. Gu Xingshen hurriedly asked them to stop, although they didn't know what the situation was ahead, it was better to wait for a stop to make sure before continuing to walk forward.

"What's wrong, are you okay?" Listening to the voice, Gu Xingshen should be next to him, I don't know what happened to Gu Xingshen just now, Cheng Qingxue only felt that someone suddenly grabbed his hand, judging from that strength, it didn't look like Gu Xingshen's prank.

"I just slipped under my feet and almost fell, I don't know if there is a small pit in front of me or what, who is the fire breaker, light it first and look at the road. "They are not familiar with the situation here, it is better to be cautious, even if he is not responsible for himself, he must be responsible for Cheng Qingxue.

Cheng Qingxue took out the fire fold from her pocket and lit it carefully, and without hearing the explosion, she knew that there was no such mineral in the vicinity.

It's just that when they saw the situation ahead, they couldn't help but gasp and take a step back in unison.

"There's a cliff ahead, but we don't know how high it is, and we're probably going to be stuck here. "The cave can't get out

, even the only way is a cliff, there is no way to continue to go down, and several people suddenly have no countermeasures.

Cheng Qingxue thought for a moment, and said to everyone uncertainly: "Maybe there is a way to measure the height of this cliff." ”

"What's the solution? Come on, we can't be stuck here forever. Jin Jianguo was like he had just reacted that he was trapped, urging Cheng Qingxue to hurry up and say the method.

Only Wu Haolin knew that he was only interested in this knowledge about academics, and had no other meaning.

"Jianguo, you take out the watch, I'll throw the fire fold down here, calculate the height of this cliff by the time he fell, it's very empty here, we all have an echo when we talk, if the fire fold falls to the bottom of the cliff, it will definitely make a sound. ”
