After Wu Tao and Duan Jinyan's men exchanged fire, the scene became extremely chaotic.

Duan Jinyan's men, hiding in the laboratory, began to fight back with the pistols they carried.

"Da da da!"

Immediately afterwards, the sound of submachine guns could be heard from the hall outside.

Under the overwhelming firepower, Duan Jinyan's men couldn't even raise their heads.

"Bang! Bang!"

One of Duan Jinyan's men, holding a pistol, stood at the door and fired several shots outside before being shot in the head and collapsing to the ground, convulsing.

I saw this person fall, picked up the gun from the ground, and pointed it directly at Duan Jinyan.

"Don't move!"

Seeing my movement, someone next to me pressed a gun against my head and said, "You fucking think this through. If anything happens to us, not only will you be killed, but your neighbor's friend will be in the same boat!"

Hearing the other party threaten me with the well, I ultimately did not pull the trigger.

"Ding-dong!"

Just then, a grenade was thrown directly into our room from outside.

"careful!"

When the leopard saw the grenade on the ground, it kicked over the corpse and placed it directly on top of the grenade.

"boom!"

The grenade exploded beneath the body, spraying blood all over the room.

"Who the hell threw that grenade?!"

Wu Tao roared from outside, "Charge in and capture him alive! We can't let Duan Jinyan die so easily!"

The leopard peered outside and saw Wu Tao's men marching forward with shields in hand. It roared, "Wu Tao, let's talk, okay?!"

Wu Tao shouted, "Go to hell! What's there to talk about with a lackey like you?"

Duan Jinyan then turned around, glaring at the leopard: "Wu Tao has gone mad, can't you see? He won't listen to anything you say now, and besides..."

"Bang!"

Before Duan Jinyan could finish speaking, Leopard pulled the trigger and shot him in the head.

Seeing the leopard's movements, my mind went completely blank.

This is insane!

They've all gone fucking crazy!

Today, I was first attacked by zombies, and then Duan Jinyan appeared out of nowhere.

In the end, he died at the hands of the person he trusted most.

Although I hate him so much, I even thought about killing him with my own hands just now.

But I was still shocked to see him die in front of me.

Leopard shot Duan Jinyan dead without hesitation, then threw his body out the door: "To be honest, I noticed something was off about him lately! Only after you told me did I realize he really seemed like one of us! Now that I've killed him, we have no grudges against each other, so let us out, okay?"

"Damn it! Damn it!"

Upon seeing Duan Jinyan's body outside, Wu Tao's voice grew even angrier: "I told you, only I can kill Duan Jinyan! What right do you have to kill him! Damn it! Charge in and kill everyone inside, leave no one alive!"

"This madman!"

Hearing Wu Tao's roar, Leopard picked up a gun and tossed it to me: "Don't just stand there, now only you can save yourselves! Brothers, fight them!"

"Bang! Bang!"

I took the leopard's gun and fired two shots outside, but Wu Tao's men, holding shields, were steadily advancing, and our pistols were completely ineffective.

The enemy closed in and threw a stun grenade in.

I saw something fall at my feet and quickly covered my ears.

"Boom!"

The stun grenade exploded in the confined space, instantly deafening me, and I staggered to the ground.

Although my eyes were not affected by the bright light, I still felt dizzy and my vision kept blurring, making it impossible to see anything clearly.

I don't know how much time passed, but I finally regained some of my hearing and could feel that the gunshots outside had become more muffled and rapid.

At first, I thought it was because my senses were out of balance and I heard some noise.

Later, it was discovered that there were indeed more gunshots outside.

Just when I thought the gunshots were Duan Jinyan's men arriving, I heard Wei Shengnan's familiar voice: "Duan Shenxing, is that you? Are you inside?"

I heard Wei Shengnan's voice and shouted back, "I'm here!"

Soon, figures began to move outside the laboratory door.

When the gunfire subsided, I knew that Wei Shengnan and her group must have successfully launched a sneak attack and won. I tried to get up, supporting myself on the ground.

But I have no feeling in my body at all.

He glanced at his body and saw that he was covered in blood, his clothes stained red with blood.

Just now, while I was feeling dizzy, the other side threw a grenade in.

Countless shards of metal were embedded in my body.

The next second, a sharp pain spread throughout my body, and my vision gradually went black.

Out of the corner of my eye, I saw the blood beneath me flowing like a small river.

First came Qu Ruilin's voice from outside: "Duan Jinyan is dead!"

Immediately afterward, Song Laosan rushed into the laboratory. Seeing my movements, he shouted, "Quick, someone come quick! Something's happened to Xiao Duan!"

"Duan Shenxing!"

Wei Shengnan ran towards the sound, saw my appearance, turned around and shouted, "Doctor! Where is the doctor? Come quickly and save me!"

Soon, a doctor ran into the lab, knelt down to examine my injuries, and shook his head at Wei Shengnan, saying, "The shrapnel has damaged an artery. If he doesn't receive a blood transfusion soon, he won't survive!"

Song Laosan pointed to the corpse at the door and said, "That person outside is his biological father. Can we take his blood?"

"It's theoretically possible, but technically impossible! The blood in the body has stopped flowing, and we only brought IV tubing, not syringes, so we can't draw any blood!"

The doctor explained, "I didn't expect this to happen either. I didn't bring my toolbox when I came, and he only had two more minutes to live. There was no way to save him."

Hearing the doctor's explanation, I felt somewhat desperate.

Due to blood loss, I was both thirsty and cold, and I could no longer speak.

I never imagined that I would see Duan Jinyan die right in front of me.

I never imagined that I would die with him.

Just then, the leopard's voice came from the side: "Use mine."

The doctor looked at the leopard: "We can't find a match. Not just anyone's blood can be used! Even if you have type O blood, it won't work!"

"My blood is acceptable!"

The leopard took a deep breath: "I am his biological father."

"What did you say?"

Everyone was stunned when they heard this.

Qu Ruilin froze for two seconds, then grabbed the leopard by the collar like a madman: "You're Duan Jinyan?"

As Qu Ruilin moved, a stream of blood spurted out from the leopard's back.

Upon seeing this, Song Laosan examined the leopard's wounds and blood, and said in a deep voice, "He's been shot; his lung has been injured!"

"I won't live much longer! Cough cough!"

The leopard coughed a few times and looked at everyone: "While I still have the strength to live, let me give him a blood transfusion first. I will tell you everything you want to know!"
