Chapter 20

Last night, there was a pleasant rainstorm in Beijing, which extinguished the sultry heat in late summer and early autumn overnight, as if the whole world was open to breathe.

The weather was very cool after the rain. The whole squadron trained on the playground to prepare for the annual martial arts competition.

In the previous martial arts contests, Ren Yudu reported several group and individual events, but since he became a squadron captain, he didn't have so much free time to train. Moreover, it was not appropriate for him to compete with a group of teenagers and young people in their early twenties. However, he and Qu Yangbo would participate in some group events to reflect collective honor.

At this time, the alarm bell suddenly rang.

Ren Yu looked at a group of soldiers in combat clothes and carrying empty shouts practicing weight-bearing running. He grinned and said, "let's go. There's no need to change clothes."

A group of people rushed into the garage. The correspondent on duty ran to Ren Yu and reported: "Ren team, underground operation of sewage well is poisoned."

Ren Yu shouted, "change your emergency clothes!"

The soldiers howled and began to change their clothes quickly.

They often wear two sets of clothes for police. One is the dark blue fire fighting suit embedded with fluorescent band, which is insulated and flame retardant, wide and heavy, and the other is the orange rescue suit, which is suitable for non fire rescue, which is light and slim.

"Yes."

Put on his clothes, Ren Yu drove out the rescue car and ladder car and rushed to the community shown on the police list. At the same time, he called the alarm person: "Hello, who are you, the person in charge of the community?"

"I, I, I'm not, I'm a security guard."

"Tell us about the situation."

"Our community was flooded when it rained heavily, so we sent someone down to repair it. Three people didn't come up, and then..." the security guard was nervous. "Three people were sent to save them, but they didn't come up."

"Don't send anyone down!" Ren Yu shouted, "before you sent someone to repair, did you drain water? Did you do air replacement? Did the people who went down have safety protection?"

"I, I don't understand. I don't care."

"Where's the steward? Where's the property?"

"Beside..."

"Wait, don't do anything!" Ren hung up the phone and couldn't help scolding, "accidents happen every year and publicity every year."

Gog reluctantly said: "publicity every year, accidents every year."

The rescue car drove into the community. A group of people had been surrounded in front of the sewage well. The property and security guards were putting down the rope in vain.

Ren Yi ran over with people. The smell in the sewage well could almost make people faint. When he looked down, the shaft wall was narrow and the underground sewage rippled. He couldn't estimate how deep it was. He shouted, "where's the person in charge!"

A middle-aged man came over. He was blue with fear: "I, I'm the manager."

"Did you send someone down?" Ren Yu glared at him fiercely, "don't you drain water before you send someone down?"

The manager trembled and said, "the water is not deep. The master can't say it when he goes down."

"Did you do air replacement? Did they wear masks?"

The manager shook his head: "they brought masks and fire! Fire, fire is not out, there is oxygen!"

Ren Yu took a deep breath. Long term closed sewage wells usually have thin air, but air does not mean safety at all, because there may be a variety of toxic gases, biogas, carbon monoxide and hydrogen sulfide, each of which is fatal.

Many workers go down the well without knowledge, experience and equipment. If the management doesn't understand anything, it is to send someone down to die. There are many accidents every year due to illegal underground operations.

Ren Yi squatted down and motioned about the wellhead, with a diameter of about 70 or 80. He shouted from the sky. His physique was very difficult to go down. He commanded: "Sun Qingming, Liu Hui, ah Wen, Xiao Tao and Koizumi, you five are thin. Get ready for the rope."

"Yes!"

Li Sa took the camera and began shooting. Recording the scene was the work of the special duty class.

The soldiers helped five people string the rope, and sun defined the first row to get ready to go down the well.

Suddenly, Ren Yi stopped sun Qingming. He turned to the manager and looked fiercely: "did you cut off the water from the upstream?"

The manager said in a dumb voice, "I..."

"Fuck you..." Ren Yike made an impulse to hit people, "hurry to turn off the valve!"

The manager hobbled off.

Ren Zhuchong and Li Sa said, "did you call the police? Let Hongwu branch come and catch people."

"OK."

Ren Yi pressed sun's shoulder and gave him a firm look: "pay attention to safety."

Sun Qingming blinked at Ren Yi and said with a smile, "I don't know who can do this dirty and smelly work. Look, if you win at cards, the leader has to pay a price."

Ren Yu smiled and scolded, "bitch, go and go back."

Several people put on masks and climbed down the ladder.

Sun Qingming landed first. The sewage suddenly spilled over his thighs. He shouted, "team Ren, the water is at least 60 deep. Just in case, transfer a drainage truck."

"OK, report at any time."

Ren Yu pressed the intercom: "corps, we need a water pump truck."

"Received."

The security guard who called the police said, "there is a water pump in our underground garage."

"Bring it quickly."

Sun Qingming walked in carefully. The sewage pipe was dark, and the depth of his feet was different. The light on his helmet was like shooting into a black hole, and his role was very limited.

Soon, they found a man in a security uniform who came down to save people. He sat in the well and was unconscious.

Sun and Liu Hui picked him up and handed him to Arvin at the back. Arvin picked up the man, folded him back to the wellhead, tied him with a rescue rope, and the soldiers above pulled him up.

They continued to walk in and found two more. One was still alive, but the other had fallen into the water because of coma and had no pulse. Koizumi and ah Wen, who turned back, carried the man back.

Ren Yu looked at the corpse and asked, "Sun Qingming, how's the situation?"

"I found the fourth one. There's still gas." Sun Qingming said, "Liu Hui and Xiao Tao, it's too far. You carry people back together."

"No, you're not safe down there alone."

"It's all right, Ren team. I'm tied with a safety rope. We've been walking for dozens of meters. It's particularly difficult to walk here. It's too slow to carry it alone."

Ren Yu hesitated: "well, report at any time."

Suddenly, a scream came from the intercom, and everyone's heart sank. It was Xiao Tao's voice.

"What's the matter with Xiao Tao?"

"What, something stuck in my leg!"

Liu Hui squatted down to touch, but he couldn't put the comatose down. He said urgently, "the water is too deep to see clearly."

Sun said, "do you want me to go back?"

Ren Yu said, "no, Koizumi, ah Wen, go back and have a look."

Xiao Tao said, "don't worry about me first. Take someone out first. This person is dying."

They quickly pulled up the people saved by Koizumi and Arvin. They turned back again to help Xiaotao.

Liu Hui said, "you carry this man up first. Xiao Tao, don't be nervous. I'll touch it first."

Koizumi and Arvin took their men and carried them out of the well. The two have carried people back and forth for three times. Their physical strength is overspent. Ren Yu asks them to come up and prepare to go down by themselves.

"Ren team, how can you get down? It's too narrow." Gog frowned at the wellhead.

"Gog, now you command." Ren Yu said, "I'll go down first, hold my breath, and then you put down the empty call for me."

"I'm kidding!" Gog cried, "it's too dangerous, no!"

"I say yes, come on." Ren Yi said, "no one can go down."

Li Sa ran over: "Ren team, let me go down. I'm the thinnest."

The soldiers present were stunned and looked at Li Sa in amazement.

Gog frowned and said, "don't make trouble. You can't go down here."

Li Sa said anxiously, "have I ever been absent or lazy from your usual training? I have no problem with my physical strength. Let me go down."

Ren Yi was struggling, so he heard sun's voice coming from the intercom: "team Ren, I found the last two people, one of them is still alive."

Ren Yu looked at Li Sa and said in a deep voice, "bring equipment."

Li Sa turned and ran back to the rescue vehicle, put an empty call on his back and ran back.

Liu Hui's voice also came: "Ren team, Xiaotao's legs should be the aging lifting pump pipe to the card owner, and need to be sawed."

"I'll take it down." Ren Yi said, "I still have to go down. Li Sa is not enough."

Gog couldn't persuade him, so he had to say, "you go first. I'll send you Kong Hu and chain saw."

Li Sa went down the well first. Ren Yu held his breath and quickly climbed down. He had held his breath, but he still couldn't stop the pervasive stench. He felt bursts of tumbling in his stomach and almost spit it out. Gao Ge tied the mask and air bottle with a rope and put them down. Ren Yu quickly equipped himself before he took a breath.

Carrying a chain saw, they went deep into the sewage well.

The pipeline is not cleaned all year round and is full of sundries, sludge and algae. It is muddy and different in depth when stepping on it, which makes people feel particularly disgusting. Indescribable dirt is also hung on the pipeline wall.

As he walked, Ren asked, "you three report the empty call surplus."

“32％。” Sun defined, "it should be enough for me to bring this alive."

"We are both 39%." Liu Hui said.

Ren Yi said, "Sun Qingming, I'll send Li Sa to support you now. Before she arrives, you stand by and don't waste oxygen."

"But..."

"No, but stand by."

In theory, the air respirator on their back can provide people with 45 minutes of breathing, but this theoretical value will be affected by many factors such as weight, temperature, mood and amount of exercise. Especially when the amount of exercise is large, oxygen consumption is particularly fast. For safety reasons, they generally require soldiers to withdraw from the scene of the accident when the air content is only 15 minutes. This is because most of the environment and terrain at the scene of the accident are complex and easy to get lost and trapped. They reserve 15 minutes to allow time to deal with emergencies.

They find Xiaotao and Liu Hui. Li Sa continues to go forward to support Sun Qingming. Ren Yu holds a chain saw and discusses with Liu Hui how to cut it.

Xiao Tao's leg was stuck underwater and couldn't see anything clearly. Ren Yu wiped it for a long time. He was not sure. He asked, "is the pump coming?"

Gog replied, "here comes the pump truck."

"Smoke quickly." Ren Yu said, "Xiao Tao, can you bear it? I'll touch your bones."

Xiao Tao said, "it hurts a little, but it's okay. I can bear it."

Ren Yu nodded: "I don't dare to cut, for fear of hurting your leg. To be safe, pump water first, Liu Hui. Go back and change the air bottle, and then bring one to Xiao Tao."

"Yes."

As soon as Liu Hui left, they listened to a strange noise from the depths of the sewage well, as if something had been evacuated, and then there was another "roaring" sound of water.

Ren Yu scolded: "there is sewage on it!"

Sewage gushed from the depths of the well.

Li Sa has seen sun defination, but there is still a distance between them. Sun defination does not honestly stay in place. He knows that every second of delay will reduce the hope of survival.

Sun Qingming stood against the wall to resist the impact of sewage. When the water hit them, the maintenance worker who had fallen into a coma suddenly woke up. He shouted in horror and suddenly hugged sun Qingming, just like a drowning man grabbing a driftwood. He used all his life to catch the man he was clinging to.

Sun defination was caught off guard. He pulled him down and dragged him into the water. His face hit something hard and broke his mask. He saw chapped marks in front of him, and then a cloud rushed in.

He and the repairman were fluttering and struggling in the dirty and smelly water. He choked the water and inhaled the poisonous gas, and began to feel dizzy in front of his eyes.

Li Sa shouted, "platoon leader Sun!" She ran to Sun Ming, but the water had gone over her crotch, and she was struggling.

"What happened?" Renyi emergency road.

"Platoon leader sun fell down."

"Sun definition, sun definition! Speak!" Ren Yu cried.

Sun did not answer.

Ren Yi said, "Liu Hui, are you back?"

"I'll be there in a minute. I'll take care of Xiao Tao. Go and see sun."

Ren Yi Ran to the depth of the sewage well.

Li Sa finally ran to sun definition. The repairman fainted again and fell into the water. Li Sa helped sun definition up first. Seeing that his mask was broken and his eyes were muddy, he had fallen into a semi coma: "platoon leader Sun!"

Li Sa held her breath, took off her mask and put it on Sun Qingming's head. Sun Qingming coughed and breathed hard.

Li Sa laboriously fished the repairman out of the water, but he had lost consciousness and couldn't stand. Li Sa asked him to sit in the water, raise his chin and expose his mouth and nose to the water.

After sun defined breathing for a while, Li Sa took off the lower cover and put it back on her head. She looked at the way back again and again, looking forward to the man who could reassure everyone as soon as possible.

Finally, a small light source flickered, and then it was gradually amplified. A figure came running hard.

Li Sa shouted, "Ren team!"

Ren Yi Ran to the front and saw sun Qingming's face pale: "what's going on!"

"Platoon leader Sun's mask is broken." Li Sa said, "the repairman still has a pulse."

Ren Ying took off his mask with bated breath, buckled it on Sun Qingming's head, and pushed him hard: "brother, hold on..."

Sun defied but could no longer insist. He completely fainted.
