There were four people in total, and the three of them walked side by side in the mine, covering the width of about three meters, and the distance between them was just enough to see the shadows of their teammates. The remaining one was in the back, holding a shield with a light machine gun on it.

Only the footsteps are moving, and the upper body is unusually steady, like a gyroscope that can automatically calibrate and maintain the level, slowly approaching this side in a relatively static and smooth state.

Seeing this, Kasia immediately took off his shoes and walked towards the four of them in a gentle and silent manner. The detection of the sound wave quickly calculated the speed of the enemy's advance, and Kasia calculated the distance between himself and the four, and immediately ripped the four steel-hulled bombs from his waist and pulled off the pull ring. According to the current formation of the four people, after a few steps, Kasia placed the steel-hulled bombs in the best position that he had calculated.

Turning around and retreating back nearly thirty meters away, Kasia, who had drawn his revolver, stood in the middle of the mine, "watching" the four people in front of him to keep their current speed and continue to move forward. Mentally counting the seconds, and when the number came to five, Kasia raised his revolver and aimed it at one of the enemies in the center. After doing this, the seconds come to "three" and then "two".

"One" Kasia's mouth softly spat out the number, and four steel-hulled bombs exploded. The calculated speed kept the bomb right under the feet of the four people. The blast lifted all four of their bodies up, and the attacks from outside their attention gave them no time to react.

Kasia then fired, and four bullets captured the four people being lifted by the explosion more than a meter high body, either the head, or the heart of the chest, one by one by the bullets through the holes. After reloading, Kasia had already gone to the dead four. All the good things on his body are carried by him, and the specifications and quality are far from the standard line of the rebel surgeons.

Replacing all the steel-hulled bombs with reinforced ones, Kasia picked up the light machine gun, grabbed the bullet pouch and hung it around his waist, picked up the two bulletproof shields and snapped them together, and rushed to the location of the steam furnace. High-frequency sound waves began to penetrate the walls and rock formations of the common room, revealing the state of the remaining five people.

The movement had already been captured, and the captain of the team was among them, and Kasia could "see" the strange huge size. Instead of immediately returning to the mine due to the explosion, the five men left the steam furnace and set up a defensive line on the edge of the rest room, observing the movement of the intersection through the rock wall.

The team leader picked up the communicator at this time, and Kasia subconsciously turned his head to look behind him, in addition to a few people standing in the mine three or four hundred meters away from the intersection, there were several other teams in the staggered mine network farther away, and they were rushing towards here and sealing the three mines.

"There is a high probability that there are also teams on the surface of the mine that are hurrying here, preparing to besiege and destroy our 、、、 of the steam furnace. Kasia raised his light machine gun, the muzzle of which was pointed at the hole in the mine from the rest room to the intersection, and walked forward step by step. He wanted to wait until the opponent attacked before counterattacking, but he always met these people in the end, and Kasia felt that it would be better for him to take the initiative.

Holding a light machine gun in one hand, by now, in addition to the heavy machine gun that uses blue and silver bullets, Kasia may have forgotten that there is such a thing as recoil on the firearm. Removing the two reinforced steel-hulled bombs, Kasia thought of a plan to force his way in, and then pulled off the pull ring and began to count the seconds. The team that came behind them also narrowed the distance in a matter of seconds, and at this moment they had already met several people standing in the mine waiting in the cave.

Knowing that the encirclement network was about to be formed, Kasia threw two steel-hulled bombs one after the other. The fist-sized ellipsoid perfectly followed the calculated line and fell to the two of them. At the same time as throwing the steel-hulled bomb, Kasia rushed to the lounge at full speed as if he wanted to snatch the time when the steel-hulled bomb fell next to his target.

In the end, it was Kasia who took the first step to press the trigger of the light machine gun, and the rapid-fire light machine gun with a rate of fire of 1,600 rounds per minute made the bullets look like connected streamers. Firmly controlled by one arm, it can ensure that every bullet will land at the same point, but it can ensure that all the beams of bullets will fall in a very small area the size of a matchbox.

The moment they rushed in, two steel-hulled bombs exploded almost simultaneously. The bullets of the rapid-fire machine gun were also in the next second, and the combined power of nearly two dozen bullets made one person's bulletproof shield bulge inwards into a fist-sized convex hull.

The enemy had already begun to attack, and the muzzle flame of the rapid-fire machine gun could indeed be a visible target in the steam. Kasia didn't let her body stay in the same position for even half a second, and when she approached the wall of the lounge sideways, a person hit her with a shield and felt the direction.

"Boom!"

Kasia responded with a very gentle movement, but the moment the person touched Kasia, it almost flew back and hit the wall, making a crunching sound. Kasia then kicked the man's shield with a crackling sound that shattered and shattered, sending a shock to the feet of the remaining four.

The next moment the shield was struck, the impact of the bullet hit. Cassia kept his shield-holding arm at all times, drawing irregular circles with his shield in order to prevent certain parts of the shield from being attacked by too many bullets. The rapid-fire machine gun spews fire again, finds the man's shield from the beginning, and hits the inward convex hull. This time, the shield was directly penetrated, and the bullet stream immediately opened a huge blood hole in its body.

The barrel of the gun had turned dark red, and Kasia decisively threw away the rapid-fire machine gun, relying on speed and agility to crash into the nearest person, and when it bounced it away, he pulled out the wheel to find the gap in the shield defense, allowing the bullet to burrow into the person's body. The sound of the gunfire also died down at this moment, and in the sound wave, the remaining two people had already left the break room and turned to the mine that connected to the location of the steam furnace.

Nearly ten steel-hulled bombs were thrown into the lounge, and Kasia didn't dare to slap them back with his shield, so he immediately retreated to the corner, and on the way, he unfolded the two shields tied together in front of him.

The explosion blasted several small spaces in the flowing steam, and the next moment some were filled in again, and the smoke was immediately carried away. Kasia closed her shield and rushed out of the break room. The remaining two people were separated from each other on both sides of the mine, and immediately approached them when they sensed the movement.

The speed increased a few times again at this moment, and without giving the two of them time to react, Kasia grabbed the shield with both hands and smashed it directly at their unusually large captain.
