The scene was instantly controlled by Zhang Yunfeng. When Su Nanyan rushed in front of Zhang Yunfeng, she was already in tears. Seeing Zhang Yunfeng's left arm spurting blood, her heart felt like it was being stabbed with a knife.

"I'm sorry, it's all because of me, I'm sorry …"

Su Nanyan cried like a teardrop. Zhang Yunfeng quickly comforted her and said, "Don't worry, my injuries are fine. They went through my wounds, but not my arteries."

With the Top Medical Skills Package, Zhang Yunfeng was very clear on the extent of his injuries.

Hearing Zhang Yun Feng casually talking about his injuries, Su Noyan's heart hurt even more. She quickly took off her coat to help Zhang Yun Feng bandage his wounds.

Zhang Yunfeng saw that she was crying and could not take the anger out of his. He could only constantly console her that he was fine, and so he let her bandage him up.

It was at this moment that the security guards of the hotel heard the gunshot and rushed over. Soon, almost all the security guards of the hotel came rushing over along with the staff and manager.

Zhang Yunfeng hurriedly said, "These people are the kidnappers. First, hold them down and then report them to the police!"

"It's already been reported to the police." The hotel manager was scared to the point that his face turned pale. The others also looked frightened. The security guards had never experienced such training, so they couldn't calm down for a while.

Zhang Yunfeng raised his voice and said, "Tie these people up and wait for the police to arrive!"

The hotel manager hastily turned around and told the security guards, "Don't just stand there. Hurry up!"

More than ten security guards rushed over and stopped the three people as well as the one lying on the ground. Zhang Yunfeng pointed to the roadside and said, "There are a few more over there, they probably don't have much combat strength left. Hurry up and don't let them escape."

Seven to eight security guards and five to six service staff members hastily ran over. Only then did Zhang Yunfeng feel relieved. He pushed back the hammer of his pistol and stuck it into his waist.

Due to the sudden appearance of two people blocking her path, she was not taken away by them. However, those two people seemed to have been shot. It had already been a minute and they still didn't know what was happening to them.

Zhang Yunfeng ran over to check and was surprised to find that one of them was Chen Feng, who was in the same room as him, and was greatly surprised in his heart. However, Chen Feng's injuries were not too optimistic, Zhang Yunfeng had ripped open his clothes, and the blood from his wounds instantly gushed out.

The place Chen Feng was hit was in his lungs! Moreover, the amount of his blood loss was enormous. It should be due to his ruptured pulmonary artery!

From Zhang Yunfeng's naked eyes, he could tell that Chen Feng had lost at least 1300 to 1500 milliliters of blood. From the looks of it, he was already in shock, his face pale, and his vital signs were weak.

If he didn't think of a way to give first aid, Chen Feng could die in a matter of minutes!

He did not have any tools to stop the bleeding, nor did he have a tourniquet. The only thing he could do was to use the simplest method to temporarily help him stop the blood loss, and then, Zhang Yunfeng found the location of the blood vessel near his heart, and used his thumb to strongly press it.

Suppressing the blood pressure and blood loss from the source would allow the blood pressure of the entire artery to be controlled. Although it was impossible to stop the bleeding completely, after losing the pressure and being pressed down, the blood flow speed of the wound would be reduced by a lot.

Immediately, Zhang Yunfeng looked at Little Four, who was on the side of his stomach and was currently curled up on the ground, clutching his wound and howling in pain. However, judging from his current state of mind and the speed at which his wound was bleeding, he did not have any injuries to his arteries, furthermore, he did not have any major injuries to his organs, so his life was temporarily in danger.

"Call 120!" Zhang Yunfeng shouted, and the hotel manager quickly took out his phone and made a call.

She did her best to control herself from looking at anything other than Zhang Yunfeng's wound, only by doing so would she be able to maintain a certain level of calm, while Zhang Yunfeng's right hand was constantly pressing down on Chen Feng's heart, not daring to relax in the slightest.

At this time, the unconscious Chen Feng suddenly began to cough violently. His entire body was shaking non-stop as he spat out a large amount of blood and saliva mixed together, causing Zhang Yunfeng's heart to sink!

If he wasn't wrong, there was an 80% chance that Chen Feng had accumulated blood from his chest, which was also commonly known as his blood thorax! If he accumulated blood in his chest, it would cause his lungs to collapse from the immense pressure. That way, even if he stopped the bleeding from the wound, he could die from suffocation in a few minutes!

After that, Zhang Yunfeng took out his left arm from Su Nanyan's hand, bent over while tapping his chest with his left hand, and at the same time listening closely to the sound.

Seeing that Chen Feng's breathing and pulse were getting weaker and weaker, and that he might lose his life in just a few minutes, waiting for an ambulance was absolutely hopeless, but Zhang Yunfeng didn't have any medical equipment on hand. Otherwise, if he helped him with an intercostal cannula drainage, it would be able to relieve the pressure on his lungs.

Zhang Yun Feng did not know much about Chen Feng, nor did he know his true identity, but in Zhang Yun's eyes, Chen Feng had stepped forward at the critical moment, which was why Chen Feng did not bring Su Noyan away, and also gave him some precious time to reverse the situation later on. He owed Chen Feng a huge favor, so no matter what, he had to think of a way to save him!

"Who has a pen?!" Zhang Yun Feng suddenly opened his mouth and asked the people around him.

"I do!" Although the manager didn't know what Zhang Yunfeng wanted to do at a time like this, he still hastily took out a delicate, metallic, neutral pen from his shirt pocket and handed it over to Zhang Yunfeng, "Check if it's suitable."

Zhang Yunfeng hurriedly called out to him, and said: "Come, help me hold down the place where my finger is at!"

"No, no, no." That manager was so scared that he quickly retreated and whispered, "Life is in the sky, I don't dare to act recklessly!"

Zhang Yun Feng cursed angrily: "It's precisely because of him that you came to press down on my life! Otherwise, he might have died at any moment! "

The hotel manager still waved his hands but did not dare to step forward. Su Nuyan, who was beside him, suddenly spoke, "Let me help you!"

Seeing that she had gradually calmed down, Zhang Yun Feng nodded his head. His left hand painfully grabbed Su Nanyan's right hand, and brought her to the most important place, and asked, "Can you feel any slight vibrations?"

At first, Su Nanyan's heart was beating faster when she was held by Zhang Yun Feng, but when she heard Zhang Yun Feng's question, she forced herself to calm down, and then she nodded her head and said, "It seems like there is a force rushing out."

Zhang Yun Feng nodded his head, and said indifferently: "This is the artery near the heart, you must suppress it, the moment you release it, blood will spurt out."

"Alright."

The first thing he did was to take apart the mid-grade metal pen. He took out the pen, twisted the top part of the pen, and twisted the tip of the brush back, feeling it with his hands. Although it was made of metal, the top of the brush was still somewhat dull, far from being sharp enough to be able to pierce through, making it impossible for it to pierce through Chen Feng's ribs.

Zhang Yunfeng steeled his heart, without caring about anything else, he immediately started sharpening the tip of the brush on the concrete floor, until the top was sharpened, only then did Zhang Yunfeng pick up a machete from the ground, carefully finding the most suitable spot between Chen Feng's right ribs, and with a slight push, the tip of the machete pierced into Chen Feng's body, creating a small cut between his ribs.

Zhang Yunfeng used the tip of his saber to insert a bit of energy into Chen Feng's body. He rotated the machete and used the tip to bore a bloody hole through Chen Feng's body! The spectators felt their scalps go numb as something that caused them to crumble even more happened!

Zhang Yunfeng aimed the sharpened tip of the brush at the bloody hole that was drilled out by the blade, but Zhang Yunfeng was not anxious to insert the tip of the brush into it, instead, he used his left hand to calculate the length of the pen, his thumb and forefinger tightly pinching the calculated position, after that, his right hand suddenly pushed, and with a pu sound, the tip of the pen was inserted into Chen Feng's ribs!

This scene caused everyone to unconsciously step back. Gasps could be heard from the crowd, but the scene that followed left them amazed.

At the end of the pen container, a large amount of blood and bodily fluids began to pour out, and Chen Feng, who was originally coughing intensely, seemed to have gotten a relief in an instant, the coughing sound becoming smaller and smaller. After the pen container had put in a large amount of scarlet liquid, Chen Feng's chest was no longer moving up and down intensely, and his entire body finally calmed down. Although his vital signs were still very weak, Zhang Yunfeng was very sure that Chen Feng would not die in a short period of time.
