Douyazai said: "Fengzi, you can't spend money randomly, expensive things may not be enough."
I said: "Expensive things may not be good, but expensive things can reduce the probability of us buying bad things! Especially when we go into the water, we are not a joke, so we must buy the best and safest equipment."
Douyazi immediately said: "You know it's not just a joke. You don't know about this. CCR is good, but not everyone can use it! You need to go through strict training. If you have no experience in using it before, don't know how to change the adsorbent, don't know how to distribute the adsorbent, don't know how to use it, don't know how to use it, don't know how to use it, don't look at the sensor, and can't control your breathing frequency. If you don't do it well, you will easily get drunk underwater and get poisoned by oxygen! Once that happens, you will definitely die!"
Douyazai's face rarely showed a bit of seriousness.
He continued: "I'm not afraid of spending more money, I'm considering everyone's safety. I understand your water quality, so the equipment I recommend is the most suitable for everyone."
Douyazai licked his fingers and drew on the table, saying, "The L-shaped pool under the deep water pool is a bit like the sheep tail hole, but it is much deeper than the sheep tail hole. When we get the equipment, I will bring a few more gas cylinders to make the traction rope first, and then you can just grab the traction rope to swim, which can greatly increase safety."
"The most troublesome thing is that we don't know what the horizontal depth of the pool is, and we don't know where it is. If there are independent air pockets on the way, we can use them to place spare gas cylinders. If there are no independent air pockets, we can only change the air cylinders underwater."
"Underwater ventilator, will it do it?"
Brother Yu and I nodded and said we could do it, but Xiaoxuan said we couldn't do it very well.
In fact, Xiaoxuan is better at water than me. Her family has a swimming pool since she was a child, but she rarely uses equipment like gas cylinders and respirators.
Douyazai explained: "It's very simple. Zhao Xuanxuan, listen well. The first step is to keep it stable. Don't panic! When we go into the water, we hang a main gas cylinder, a secondary gas cylinder, and a small spare gas cylinder. When the main gas cylinder is insufficient, bite the spare secondary head first, tighten the main gas cylinder valve, disconnect the regulator, and then remove the main gas cylinder. Be gentle on the way to avoid muddying the water and affecting your vision. Then connect the auxiliary gas cylinder and take a look at the pressure gauge. If there is no problem, there is no air leakage."
Xiaoxuan frowned and said, "I heard from you, why do you feel more troublesome?"
Douyazi shouted: "Is this troublesome?! What I said simply cannot be simple! Are you a pig's brain? Don't go into the water! Let's just watch the things on the top!"
"You are the pig's brain!"
Seeing that the quarrel was about to start again, Brother Yu said, "Stop quarrel, Xiaoxuan, Yazai is also for our own good. It is not difficult to change the ventilator. You will be able to take a look at it."
Xiaoxuan bulged her cheeks and looked angry.
"Put your head, do you have anything to add?" I turned around and asked.
"Ya Zai said it very well. As he said, Yunfeng, you can count the number of equipment and how much it costs, transfer it to the person in the afternoon, and try to let the other party send it tomorrow so that we can enter the mountain next Monday."
"Don't worry! My friend is specializing in buying these equipment in Guangxi! As long as we have the money, we can receive the things soon!"
"So concerned... you guys won't take kickbacks in the middle, right?"
"Damn it! Fengzi, don't swear! What the hell can I take?? We need this kind of equipment now! I just met such a friend before!"
I said, "Don't be excited, I'll be kidding."
Douyazi rolled his eyes and said, "In addition, there are four points about cave diving. I didn't talk about these four points just now. These four points are also very important, so everyone should pay attention."
"First, underwater guidance rope is navigation, it is lifeline. No matter what happens, you cannot let the guidance rope leave your sight."
"Second, always pay attention to the gas cylinder margin. Keep at least one third of it, otherwise you will not be able to go back."
"Third, once you feel your fingers numb or your head is dizzy, you may be signaling to the people around you in time, which may be caused by an intoxication."
"Fourth, you must maintain a mid-swimming posture throughout the whole process and know what a mid-swimming posture is? It means paying attention to the distance from the top of your head and under your feet, trying to keep yourself in the center position, and don't move your hands around, and just paddle slowly with your flippers."
Douyazai talked about many things to pay attention to when diving. He Jiang was very serious, and we listened very seriously. I guess it was the last time when the Sheep Tail Cave made him feel scared.
After the meeting and discussion, they went back to the house to sort out their things. There was a small box under my bed, which contained some of my personal belongings. The box has not been opened for a long time.
There is itchy powder inside, several replaced mobile phones, each with a phone card, and a draft of the Wanbao book that I had previously planned to write by Doctor Fan. Unfortunately, I only wrote 300 words for so long, and there is also a bottle of unsalted aphrodisiac wine. This wine was given to me by Uncle Drunkard before, and I can't use it now, so I keep it.
There is also a dark layer at the bottom of the box.
I unzipped the zipper and took out a flute wrapped in velvet.
I tried to blow it by the way, but it couldn't blow it, and it couldn't blow it.
I have never seen this flute for anyone.
I watched for a long time, then put the yellow coarse fragrance and flute that the old seacock gave me together, wrapped it carefully, covered it with a piece of cardboard to protect it, and finally pushed the box back.
.....
At night, I tossed and turned and couldn't sleep. I always wanted to take out the flute and look at it, but the rational voice told me not to look, and I couldn't sleep even more after watching it. Everything was over and I had to look forward, so in order to divert my attention, I boarded QQ.
Looking at the lively speeches in the wild group of "Brother's Night Walk", I joined them, talking about all kinds of jargon and slander, talking about how to find people to join in, where there are ancient tombs that can make people turn over overnight, talking about various explosive tools, and Luoyang shovel cyclone treasure hunting maker. The mobile phone screen was not big at that time, and so much news in the group looked like scrolling.
A sudden whim.
I typed and posted in the group and said, "Have you heard of the Northern School Shenyan Peak? I am Shenyan Peak."
"Good guy, the Shenyan Peak is here. I am your ancestor Yao Wenzhong."
"You are Shenyan Peak, so who am I?"
An account named Jinyi Yexing-Shenyan Peak sent a message saying.
"Haha! Brother, you are so funny. Can the Divine Eye Peak come to our wild group? If you are Divine Eye Peak, I will be your master, the Northern Sect Silver Fox, call me Master!"
I was about to type, but suddenly it rang.
"Brother Feng, I saw the message you sent, and I was so laughing to death. Didn't you pay attention? There are more than 20 Divine Eye Peaks in the group."
It's Xiaoyang.
I smiled and typed: "You're not doing anything there?"
"It's okay, Brother Feng, have you found out about diarrhea?"
"It may be caused by accident if I didn't find out."
I didn't lie, I really can't find out now.
After two minutes, Xiaoyang sent me a message and asked me: "Where are you now? Brother Feng, I miss you a little."
I speeded up my typing.
"Don't miss me! What do you miss me? If you have nothing to do, you can read more information when you are idle! Look at the information sent by the archaeological team! It will be helpful for you to improve your abilities!"
Xiaoyang sent a smiley emoticon pack.
"I won't chat anymore, you can recover from your injuries! See you later!"
I threw away my cell phone and prepared to turn off the lights and go to bed.
As a result, just as I got out of bed, I suddenly heard a knock on the door.
It's a head.
After I put my head in, I closed the door. I saw that he was wearing long clothes, long trousers, labor protection shoes.
"Take your head, you're..."
"Yunfeng, don't make a sound, lock the door, take things, turn on the lights, and all of us walk through the back door."
“Where to go?”
Chapter completed!
