, the fastest update of the protagonist Luo Ran Lanxing, the strongest female academic!

In the field, Luo Ran ignored the comments about her by the people around her and said decisively in a deep voice:

"Dong'er! We can't hesitate any more now, it will be too late!"

Luo Ran's words were so impactful that the hesitation that was still wavering in Xu Donger's heart was instantly shaken away.

Xu Donger suddenly raised his head and looked at Luo Ran, with two strings of tears on his face, and said in a trembling voice:

"Sister, I believe you, please save my grandma!"

After the words fell, everyone onlookers stopped talking. At this moment, only the only granddaughter beside the old man had the right to decide whether to let Luo Ran try.

Luo Ran quickly came to the old man's side, leaned down, suddenly turned his head and said loudly:

"Avoid all men!"

Immediately afterwards, under the watchful eyes of all the ladies present, Luo Ran unbuttoned a row of sweaters on the old man's chest.

"Ah, this! How could this happen? Grandma, when did you..."

Xu Donger, who was squatting next to her, immediately saw that there was indeed an obvious trauma and bruise on grandma's chest.

"Woo...wu wu..." Tears burst out of her eyes and flowed uncontrollably down Xu Dong'er's cheeks.

"Dong'er, don't cry. The trauma on grandma's chest looks scary, but it's actually not serious."

Luo Ran stretched out his slender fingers and quickly moved under the old man's ribs. After about a moment, he let out a long sigh of relief.

"Phew! Fortunately, there is no obvious displacement of the ribs, just a slight bone crack."

After confirming, Luo Ran comforted the girl beside him who was still sobbing:

"Dong'er, it's okay. I'll use a chest strap to fix it temporarily when I get back. Grandma will be able to recover over time."

But reaching this point only explained Luo Ran's previous action of preventing the volunteer from performing cardiopulmonary resuscitation. Facing the old man who was still in a coma, the next step was the top priority.

Luo Ran raised his head and calmly told the girl:

"Dong'er, the dry cigarettes your grandma usually smokes are not refined. They contain many harmful substances to the human body, especially the lungs."

“As grandma gets older and harmful substances accumulate in the lungs, [pulmonary bullae] lesions occur, compressing the blood vessels in the lungs.

In addition, the weather in March has a large difference in temperature and humidity between day and night, which further causes the blood vessel walls to become dry and lack toughness.

Various factors eventually caused the rupture of the blood vessels in the lungs. The blood compressed the grandma's lungs, causing her respiratory failure, and her current situation is very dangerous."

"So next, I'm going to perform a "bleeding" treatment on your grandma!"

"Bleeding?!" Xu Dong'er was frightened. Even the passers-by who were watching changed their expressions after hearing Luo Ran's explanation!

"This sounds too scary!"

"I think we should wait for 120 to handle it!"

"Is bleeding really effective? What if something unexpected happens during the process?"

"Yes, the old man's body and bones are so weak, how can he withstand the torture anymore."

"..."

In the crowd, a variety of discussions surged toward Luo Ran.

"Silence! Dong'er, every minute and every second is precious now. If you hesitate any longer, grandma will probably suffocate to death in a short time!"

Death! Xu Donger's eyes suddenly widened, and her face suddenly turned pale! No matter what, she would never accept this outcome!

"Sister, what should we do now? Drain the blood? How can we drain grandma's blood? The 120 ambulance hasn't come yet..." Xu Dong'er said with a trembling voice and a confused voice.

Luo Ran thought quickly in his mind, why he could tell at a glance that the old man had a hidden illness when he met him today.

Thanks to those books on pathology and first aid that I read in the city library yesterday!

At this moment, the old man's condition was exactly the same as described in the book, which increased Luo Ran's confidence in proposing "draining blood".

After several breaths, Luo Ran finally recalled the simple method in the book about "draining blood" from the lungs.

"Everyone, do any of you have sharp objects on your body?!" Luo Ran turned around and asked everyone urgently.

"Sharp objects? There aren't any. Who would bring sharp objects with them?"

"Yes, girl, even if you carry it with you, you will definitely not be able to pass through the subway security check!"

"..."

Suddenly, a middle-aged woman from the crowd came out, raised her hand and said, "Can I have a plastic hairpin here? It's quite sharp!"

Luo Ran finally issued the hairpin, squeezed it with his hands and returned it, shaking his head and saying: "This hairpin is made of plastic, it is too brittle and will break easily, no way!"

Just as everyone was groping up and down their bodies, a young man who looked like a college student squeezed out and shouted anxiously:

"Girl, see if I can do this!"

Luo Ran took a paint-colored box from the young man's hand. After opening it, there was a pen lying inside!

The pen tip is sharp and the whole body is made of metal.

Luo Ran's eyes suddenly flashed with light, and he said urgently: "Okay, this is okay!"

Immediately afterwards, Luo Ran walked up to the old man. Just when he was about to make a move, he suddenly thought of something and said urgently: "Who has a lighter?"

"Matches, fire sticks, anything that can light a fire is fine!"

Hearing this, the elderly volunteer slapped his forehead, quickly turned around and ran towards the subway security checkpoint. Soon, when he came back again, he was holding a basket of lighters in his hand!

These are lighters that are "collected" at subway stations every day. Many male passengers taking the subway accidentally put them on their bodies and brought them in.

When everything was ready, Luo Ran opened the pen cap and heated the pen tip back and forth on the lighter.

Everyone held their breath at this moment, for fear that their breath would blow out the flames. They didn't know what Luo Ran was going to do next?

The entire subway station was surprisingly quiet at the moment, as if even the wind had forgotten to move.

"Ah! Sister, look, grandma... grandma, she seems to be almost out of breath!"

Suddenly! Xu Donger's exclamation broke the silence, and Luo Ran's fingers quickly reached the tip of the old man's nose.

Feeling the old man's breath as fine as a gossamer, Luo Ran knew that time was running out and could not be delayed any longer!

She bent over and squatted down, and the operation technique of "draining blood" quickly emerged in her mind. It was obviously the first time to practice the operation. But Luo Ran felt that she had done it thousands of times, and she had perfect techniques and skills.

【Read a lot of books】In the process of reading books, you can quickly understand the knowledge and integrate it with reality!

Only when the book is put to use will Hate Shao! At this moment, Luo Ran finally understood the incredible power of this skill!

In just a few seconds, Luo Ran had already made up her mind about the "blood draining" plan. Without looking back, she shouted loudly behind her: [1] [6] [6] [small] [say]

"Come a few people and help stabilize the old man!"

"Quick, why are you still hanging around!"

As soon as he finished speaking, the passers-by who were watching looked at me and then at you, but no one came forward in response.

This matter was related to the old man's life and fortune, so they didn't dare to mess around. If something happened, they couldn't bear the responsibility!

Luo Ran was shocked by the scene in front of her. Her eyes moved slightly and she sighed helplessly. She was disappointed but not much.

Facing the current situation, she can ask herself to stand up. But she is not qualified to ask passers-by to do something.

She cannot do moral kidnapping and cannot ask others to do anything, even if it is to save a life.

The scene suddenly fell into a stalemate, everyone was struggling in their hearts, and no one except Dong'er stepped forward to help Luo Ran.

After all, they still don't believe Luo Ran...

"Oh, whatever..."

Luo Ran sighed in a low voice and no longer expected anyone to come forward. She could only readjust the "blood draining" plan now.

However, at this time, there was a commotion in the crowd, and three beautiful girls suddenly walked out from the back of the crowd.

Their clear, jewel-like eyes were all shining brightly. The three of them ignored the surprise of the onlookers, all looked at Luo Ran, and said without hesitation:
Chapter completed!
