"Dad, Mom, uncle, you go back first. Xiaodan, Pengfei and I will go shopping in the bookstore and go home later."
Liu Fang secretly winked at her and told her not to forget what happened at night.
She made an "ok" gesture to show that she remembered.
"It smells so bad. My God, it seems that living in the city is also troublesome. If you smell this smell every day, can you eat and sleep?"
The three of them pinched their noses and walked forward. On the street ahead, they saw municipal workers clearing sewer pipes.
"Oops! Old Five? Old Five? Tell me, what is going on?"
Because it was too smelly, no one was watching. When the worker found his colleague who had gone down into the well and was soaking his head in dirty water, he immediately screamed, attracting the attention of Su Jian and the others.
"Sister, did something happen?"
"Go and have a look."
The man on the well hurriedly went down to pull his companion, but Su Jian quickly stopped him.
"Block your mouth and nose. There is methane inside. He is poisoned by methane."
Thinking of the textbook they had just read, Su Dan and Zheng Pengfei immediately agreed, "Yes, yes, it is biogas. The main components are methane and carbon monoxide. Inhaling excessive amounts can cause people to coma, which is very dangerous."
When the man in the well heard this, his legs immediately became weak. He asked in panic, "What should we do?"
"Go down and rescue people, hurry up, is there a rope?"
Fortunately, there was a bundle of finger-thick hemp rope on the car. The man didn't hesitate, put it on his body, covered his mouth and nose with a wet towel, and tied the other end of the rope to the wheel of the tricycle that kindly came to help.
"Go down and hold your breath as much as possible, squint your eyes, and pull him out quickly, otherwise you won't be able to save your life."
After a rope was tied around the person's waist, the tricycle drove forward and dragged the person to the wellhead bit by bit. The enthusiastic people worked together to pull them up.
"It's over. Everyone is weak. It's probably hopeless." Someone lamented.
"Yes, last year someone felt dizzy as soon as they went in. At that time, they said there was methane inside."
"Lao Wu, Lao Wu? Please wake up, nothing is going to happen to you. How can I tell your family?" The man who saved him felt uncomfortable himself, his face turned pale, and he couldn't breathe.
"Everyone, please disperse. Who can come over with a basin of water? Hurry up."
A shopkeeper brought two basins of water and poured them on the unconscious Lao Wu. Su Jian ignored the dirt on him and tore open his shirt, "Get more water, hurry up."
He was poisoned by inhaling excessive methane gas halfway down the well.
After performing cardiopulmonary resuscitation, Su Jian took out the needle from her schoolbag and inserted it into Renzhong and Yongquan points.
The lungs began to relax, the heart began to pace slowly, and the blood flowed to the whole body bit by bit. A smile appeared on Su Jian's lips.
"Send him to the hospital."
When she pulled out the silver needle, Lao Wu's complexion improved significantly.
"Ah? He was rescued? Will Lao Wu die?" The companion cried with joy.
"Don't waste time, go to the hospital for a system check, go quickly."
The crowd of onlookers burst into warm applause, "The little girl is so amazing. If it weren't for her, that person would be dead."
"She knows Chinese medicine. The last time I saw someone get acupuncture, it was Dr. Sun. He has been dead for several years."
"Sooner or later, there will be problems with this sewer pipe. A few years ago, a child threw firecrackers into it. Didn't it explode? It almost killed him."
"Oh, it's so scary. The sewer smells so bad. There's no way we can continue like this."
"People from the municipal government came again, and it was not easy for them, but they couldn't find what the problem was. It was useless even if a hundred people came."
Su Jian and the other three didn't leave. The person who came over should be a small leader.
