The banging sound was endless, and with every impact, the door panel made of special material would bulge inwards.
The tempered glass windows also began to crack due to the knocking of stones.
At this moment, Gu Nian felt that the days were like years.
Because horrible things happen slowly and approach bit by bit, every second spent at this moment becomes torture.
The knocking sound outside didn't know how long it was, and the door was finally slammed open by the monster.
The moment the door was knocked open, a monster at the door immediately let out an excited scream, folded its wings, and squeezed in through the hatch.
"boom!"
"Whoosh!"
The monster was greeted with two bullets.
Mu Yan and Gu Nian both pulled the trigger at the same time.
Mu Yan's shot hit the monster's heart, while Gu Nian's shot hit the monster between its eyebrows.
With the sound of two gunshots, the monster's body suddenly fell into a pool of blood. Its two vital organs were fatally wounded at the same time, making it instantly dead.
Although monsters are powerful and numerous, they are not invincible.
Gu Nian couldn't help but breathe a sigh of relief and aimed his gun at the head of another monster who pushed his companion away and tried to enter the gym.
When she shot and killed the second monster, the glass of a window was finally smashed.
However, due to the special characteristics of strengthened tempered glass, the broken glass was still gathered together and did not scatter. Only a hole of about one centimeter was left in the middle of the glass, which was struck by a sharp stone.
The small hole that comes out.
Seeing that the glass was expected to be broken, the monster who knocked on the glass showed an excited expression on his face.
Just when it was about to raise the stone in its hand and hit it more excitedly, a bullet passed through the small hole on the glass with a whoosh sound, and shot into the monster's chest.
It was Gu Nian who took the opportunity to take advantage of Mu Yan to kill the third monster at the door and fired a shot in this direction, successfully killing a monster that smashed the glass.
There is another monster next to that monster.
The two monsters obviously have a good relationship, and may even be related.
When Gu Nian killed one of them, he immediately ignited the anger of the other monster.
The monster looked stronger and more ferocious than the one that knocked on the glass before.
It glared at Gu Nian with a pair of scorching red eyes. It kept roaring threateningly, panting heavily, and kept baring its teeth and claws. In the end, it even threw the stone in its hand and smashed it into pieces with a bang.
Window glass.
The monster didn't care that its head and face were covered with blood marks and broken glass, and wanted to rush over to fight for Gu Nian.
The monster's ugly face with a sharp mouth and monkey cheeks, combined with the grinning and furious expression, and the effect after being processed by the bright light of pale lightning, is as hideous and terrifying as a devil crawling out of purgatory.
Gu Nian looked at that particularly ferocious and ugly face, and without hesitation shot a bullet through the monster's head, sending it and its little friend to love each other.
Gu Nian quickly eliminated the last monster on the window side.
While she continued to pay attention to the situation at the window, she and Mu Yan used bullets to kill the monsters that tried to rush in from the door.
