"How so?" asked Xiao Ju. Pen, fun, and www.biquge.info

"A long time ago, when the rain devouring forest was still green and grassy, I would often take the flounder into the mountains to play, so I still know a lot about the terrain around the rain devouring forest.

The reason why we can see it anywhere outside the city is because it is located on the top of the highest and most dangerous mountain in the middle of the mountains.

Therefore, even if there is a hidden passage under the water of the barren lake that can lead to other places, the most likely is the area of the Hot Water River in front of the broken ditch. Plaice replied.

Man Shengsheng said: "That's okay, I just tried it in the morning, it's much more convenient to take the water route than the land route, the water is unimpeded, and there is no ghost." Besides, we have a submarine, and we can easily get there without getting wet. ”

At this time, the Buddha suddenly said:

"Eh, but we can't drive submarines!"

Buddha Ke's words hit the nail on the head, and he got to the point. Man Shengsheng thinks about it, this submarine is not the stuff of these boys and girls, if anyone can start it and reach the guillotine smoothly, then it is really capable.

Ay......

Everything is ready, only the east wind is owed, and Man Shengsheng sighed unwillingly.

Tianxia suddenly had an idea: "We have an oxygen tank in our yacht, there is about half a bottle left, can you use it to dive over, we can all swim." ”

Diving forward, Man Shengsheng scratched his face, feeling a little nostalgic, because she had only swam to the bottom of the sea with her diver uncle a few hours ago, and she was still familiar with the feeling of an oxygen tank. But only half a bottle is a drop in the bucket.

Therefore, if the submarine cannot be started, the method of diving to reach the guillotine ditch, relying only on half a bottle of oxygen is simply a fool's dream. Xiao Ju was also anxious to deny:

"No, we're going to have to keep this half bottle of oxygen for use when we pass through the guillotine. ”

Man Shengsheng had a Ding Ling in his brain, and happily echoed:

"Oh, yes, why didn't I react, I'm not afraid of a guillotine if I have an oxygen tank!"

The boys and girls looked at each other, and then Liao Tianxia asked:

"What kind of place is Guillotine Ditch, it's so terrible to hear the name, why do you still need an oxygen cylinder?"

Man Shengsheng didn't have time to answer, and the jade plaice also asked:

"What is an oxygen cylinder?"

First come, first come, Man Shengsheng answered Liao Tianxia first:

"To reach the lighthouse, we have to pass through a place called Guillotine, which is said to be named because people who step into Guillotine will break their necks because they can't breathe uncomfortably. ”

"Ah, such a horrific thing, isn't this a lack of oxygen!"

Man Shengsheng nodded, thinking that compared with the confused old question of what is hypoxia, it is much easier to talk to a modern person.

She then answered the plaice's question:

"The oxygen cylinder is a huge bottle like a burden on your back, with which humans can breathe normally in any environment. ”

Man Shengsheng thought again, it was really like a popular science quiz. Then, the eyes of the little student began to flicker vigorously and said:

"Wow! There is such a powerful secret weapon, so we are not afraid of the guillotine!"

"No, I can't do it. "The Buddha is very wise.

Xiao Ju agrees with Foke's view:

"Don't be too optimistic, there are nine of us here, and if we all go, let's put aside the question of whether there is enough oxygen or not, exercise alone will increase our oxygen consumption. If one person takes another breath of oxygen in rotation, no one will have the heart and ability to move forward when I see it, and everyone will be concerned about grabbing oxygen cylinders. ”

All the staff were silent, agreeing to rely on such an oxygen cylinder alone, so many people can pass through the guillotine smoothly at the same time, which is indeed a direct explosion of difficulty. However, since there are conditions, no matter how big or small, at least there is hope.

Buddha said, "What if we carry an oxygen cylinder on our backs and use it as a precautionary abandonment?" ”

Xiao Ju looked at him with an appreciative look and asked, "Do you have any good ideas?" ”

Buddha Ke went on to say, "If we can use something airtight and easy to carry to store oxygen in it, then we can use it as oxygen cylinders, right?" ”

Liao Tianxia seemed to understand what he was talking about: "Eh, you can't be thinking of that way!"

Buddha Ke smiled wisely: "That's right, that's the method, when I used to go to a high-altitude place with my father to climb the snowy mountain, there was also a lack of oxygen there, and we did this." ”

Listening to their conversation, Man Shengsheng became more and more anxious, and couldn't help asking:

"Eh, don't be mysterious, let's be clear, what the hell is the method. ”

Buddha said:

"It's very simple, we have a lot of vacuum storage bags in our yacht, and those bags are light and have a good seal. The air is also very light, and everywhere, as long as we carry a large number of storage bags to the ditch, before entering the ditch, fill all the storage bags with air, tie the mouth to save some use, there should be no problem.

The oxygen in the oxygen cylinder is compressed, although it is only half a bottle, and it can still be emergency in case of emergency. ”

…… Once again, the whole staff was silent.

Xiao Ju and Man Shengsheng understand very well what the Buddha is talking about, this method is actually very easy to think of, but its feasibility is really intriguing. And the jade plaice Tuantuan, although they were a little confused, they could roughly guess what Buddha Ke meant.

"Have you really used this method before, won't the air run out of the bag?"

Buddha Ke also affirmed:

"Those storage bags are high-end goods, and the vacuum machine can help us preserve food for a long time as soon as it is pumped, and no air will go in, and no air will come out, as long as they are not broken on the way to the guillotine, there is no problem." ”

Xiao Ju and Man Shengsheng looked at each other, confirming each other's feasibility of the Buddha's proposal.

"What do you think?" asked Man Shengsheng.

Xiao Ju drooped his eyelids, his eyes swirled back and forth in the lower eye socket for a long time, and after thinking for a long time, he asked the jade flounder:

"Plaice, how long does it take to cross the guillotine at a normal speed?"

The plaice shook its head uncertainly and said:

"I have never been in it because I know how powerful it is, but I have heard that it is a circular valley, and if you can avoid following the trend of the valley in a circle and crossing the valley, you will definitely save a lot of time. But in that case, you will definitely have to climb the cliff. ”

If you know exactly how long it will take to pass through the guillotine groove, you can control the amount of oxygen you need. But now it is impossible to estimate the approximate time it will take, which not only increases the uncontrollability of things, but also makes everyone's hearts start to beat drums.
