These highly sophisticated fighters fly at supersonic speeds and can approach the border waters in almost a matter of seconds.

…

At the same time, inside the cave.

"Woof woof!"

A group of dogs barked one after another in the cave, and seven or eight police dogs roared in.

"Try to be as concealed as possible and shoot them quickly."

Su Tiannan was startled for a moment, then he held the automatic rifle and pulled the trigger at the police dog.

"Da da da!"

The people in the cave immediately opened fire, and bullets continued to shoot out.

"Ouch!"

Blood mist instantly erupted from the bodies of the two police dogs, and they screamed and fell into a pool of blood.

But these police dogs are well-trained. When they hear the sound of gunshots, they immediately start jumping left and right, avoiding bullets, and rush toward the shooter.

"Woof woof!"

A police dog was as fast as a black shadow. It rushed in front of Su Tiannan in the blink of an eye, opened its big mouth and bit him on the calf.

When the tearing pain came, Su Tiannan was not afraid at all. He gritted his teeth, held the gun, and fired three shots at the police dog.

"Da da da!"

The bullet ripped into the police dog's head.

Su Tiannan saw the real-time video transmission equipment worn by the police dog, kicked the body of the police dog away, turned around and shouted to everyone: "Everyone clean up the police dogs quickly and prepare to fight!"

Gunshots continued, and most of the police dogs were shot dead. Only two of them escaped in pee, and the smell of blood filled the cave.

…

Outside the cave, Xiaoke glanced at the combat instrument, turned to his deputy and said: "Judging from the sound of gunfire and the rhythm of their firing, there are no more than ten people inside. Everyone, shoot in!"

"yes!"

The gunmen immediately stepped forward. They lined up in a row and stood near the entrance of the cave. They took out the explosive bombs they had on them and threw them into the cave with a few whizzing sounds.

"Bang bang bang!"

There was a violent explosion in the cave.

"Attack!" The gunmen held their guns and rushed inside quickly.

…

At the same time, Su Tianyu stood on the hillside and saw that the gunman on the opposite side had rushed into the cave. His face sank, and he immediately cocked the bolt of his gun and shouted: "Hit me!"

"boom!"

He raised his hand and fired, directly knocking down a gunman on the opposite side.
