In the ventilation pipe on the left wall of the first floor, a person was lying in it, quietly watching a heavily armed person pass by through the louver air vent, and his eyes were full of excitement.

This person was Max, who had just returned from the basement floor, and as soon as they returned to the first floor, they all scattered, all hiding in the shadows, ready to hunt down the intruders.

Finally, when the last person walked in front of him, Max climbed out of the return air without hesitation and followed lightly.

The people who were marching didn't pay much attention to their backs, and continued to grope forward, and at this moment, the last person who was walking was suddenly pulled into the darkness, and without even a scream, he lay down on the ground silently.

In the darkness, Max let out a satisfied moan, looked at the people who were marching in front of him with a look of disdain, pressed his left hand on his headset, and spat out two words in his mouth: "Action"

As soon as the words fell, a dense burst of gunfire rang out in front of them, and after shooting and killing a few people, the gunfire stopped abruptly, and several people who attacked them quickly dispersed and fled, leaving behind a group of stunned people.

Looking at the people lying on the ground in front of him, the platoon leader at this time was already extremely angry, they had never been so cowardly since following Qin Ming, and they had already lost a few people on the enemy's own side, which made his anger completely explode.

"Chase, don't let them run" shouted angrily, and the platoon leader took the lead in the direction of the enemy's escape, and it didn't take long for gunshots to ring out in all corners of the first floor.

The second platoon commander on the other side was in a similar situation, and after a series of blows from the enemy, he also began to chase the enemy around.

The result was a shootout in various places on the first floor, or a sneak attack in a room, or a soldier holding another person and pulling a grenade.

Half an hour later, the first platoon leader and the second platoon leader met, and after the two counted the number of people, they almost collapsed, and when they came in, there were nearly 100 people, and at this time there were less than 40 people behind them, and everyone was wounded.

Now the two of them understand even if they are stupid, they have fallen into the trap of the enemy, although in the fierce battle just now, they killed no less than 20 enemies, but until now they have been in a passive state.

Thinking of this, a wry smile appeared in the eyes of the two, even if No. 1 didn't punish them if they were beaten like this, they would have no face to see people.

Biting it, a platoon leader opened his mouth and said to everyone: "We must take the second floor, even if we die, we must clear the way for the attack of the large army" After saying that, the platoon leader stood up and looked at everyone.

At this time, a soldier stood up and said hatefully: "Damn, the platoon commander is right, our two platoons were beaten like this, anyway, I don't have the face to go back to see many brothers, and the battalion commander is with them, even if I die, I will eliminate the firepower point on the second floor for the large army"

Hearing this, the more than 40 people who survived showed a look of shame, and all of them stood up and followed behind a long line.

Seeing that everyone was following behind him, a long line of leaders led the way towards the staircase.

At this time, outside the building, No. 1 and No. 2 were both looking in the direction of the building, and they had heard the fierce gunfire just now, and it was conceivable that the two platoons that went in were exchanging fire with people, and the number would not be small, thinking of this, they were even more nervous.
