The Bison strategized, and the crosshairs moved as they rushed down the stairs from the fourth floor to attack the third floor.

The people on the third floor sent reinforcements to the second floor while blocking the attack, but the first three people sent down were directly blocked by bullets at the corner of the stairs on the second and third floors.

"There are several people on the corner of the second and third floors, grenades ready." The bullet was reported to their own people as soon as possible.

The front sight at the staircase on the fourth floor was holding two grenades, and the bullet himself took a grenade, and several people with the barrel immediately suppressed the people defending the staircase on the third floor with firepower.

The front sight immediately threw the grenades, one into the corridor on the third floor, and the other on the staircase steps on the third floor, and the grenade automatically rolled down.

The three people at the corner of the stairs were about to find a chance to return to the third floor, and after one saw a grenade rolling down, he opened his mouth and cursed, and several people instinctively rushed downstairs, but found a grenade flying head-on.

This time, there was no chance to scold, and with three explosions one after another, the three people who had nowhere to hide became corpses on the spot.

The man who had been guarding the crosshairs at the corner of the hallway rushed into the nearest room when they saw a grenade rolling towards the hallway.

The downward attack on the third floor was blocked, and the people who were attacking upwards from the first floor did not achieve much for a while, and as soon as they threw the grenade, the bullet immediately hid in the nearest room, and as soon as the grenade exploded, they immediately came out to continue the defense.

Neither attack can break through the defense line of one bullet at once, the opponent's biggest problem is not strength, no matter how unbearable they are, the combined strength of so many people is much stronger than bullets.

Their biggest problem is communication, the people on the first and third floors are fighting on their own, if they have bullets and their companions on the fourth floor have a tacit understanding, not to mention the bullets, they can't even save their lives.

The successful defense of the bullet bought Xia Feifei and Cheng Lan a lot of time, and Xia Feifei was the first to solve the problem.

When the man who got in touch with the bison heard the gunshots next door, he was desperate and roared loudly into the walkie-talkie, "We have been deceived by that bastard of the poisonous wolf, this is not a mission we can get involved in at all, we all have to die, we all have to die......"

After roaring, he seemed to have refreshed himself enough, and before the puff was released, he rushed out of the room with a glaring of eyes.

However, when he rushed out of the room, he didn't even see a ghost, he instinctively wanted to rush to the room where the gunshots had just been heard, and as soon as he took a step, he saw a black whirring thing flying over.

It was like a sharp needle coming at it, and his inflated balloon was deflated at once, leaving only fear, and then trying to find a place to hide.

Xia Feifei's control of the grenade was very accurate, how could he leave time for the enemy to dodge? With an explosion, the matter was over.

Actually, Xia Feifei didn't think of killing this guy directly with a grenade, he knew that he had exposed his position after shooting, and he was going to use a grenade to open the way, and then take the opportunity to rush into the room and kill this guy.

Unexpectedly, this guy rushed out first, and Xia Feifei, who had already held the grenade in his hand, could only throw the grenade out casually.

After solving the matter here, Xia Feifei was about to help the bullet and Cheng Lan, the bullet just came over, and his face changed and he shouted, "...... behind"

Xia Feifei turned around suddenly, and at first glance, he found that the muzzle of a black hole was pointing at him, Xia Feifei did not retreat, his instinctive reaction was to immediately return fire, this decision made at the last moment can be said to have directly saved his life.

People's instinct is generally to avoid evil, and the first reaction when encountering danger is to dodge, Xia Feifei's opponent is like this, he originally took some chances, but when he saw Xia Feifei quickly turn around and point the gun at him, he instinctively dodged first and then shot.

The guns of both sides rang out almost at the same time, and then the two of them were rushed backwards by the powerful impact of the bullets at the same time, Xia Feifei only felt that he was smashed a few hard punches in his chest, and he couldn't catch his breath for a while, and leaned against the wall for a while before relieving himself.

However, Xia Feifei's opponent was not so good, and he couldn't be better either, because he was already dead, and Xia Feifei's bullet pierced directly through his mouth.

Originally, he could not die, at least he could be extraordinarily backed, but he was not decisive enough at the critical moment.

If he had shot decisively and didn't choose to dodge, at such a close distance, he would definitely be able to hit Xia Feifei's vital parts, not on the body armor.

This also corresponds to that truth, the brave wins when they meet on a narrow road.

"Huh......" Xia Feifei exhaled lightly, he didn't look at the dead opponent, he already knew why this person suddenly appeared, he must have slid down from the third floor.

Actually, Xia Feifei had already checked just now and didn't find anyone coming down, so he was ready to go to support the bullets and Cheng Lan, but he didn't expect that just after the inspection, someone came out of the room after the inspection, and this thrilling scene appeared.

There is no way, sometimes death comes so suddenly, it depends on whether you have the ability to escape, obviously Xia Feifei did it.

Since the people on the third floor were going to slide down again, there must be more than one, Xia Feifei dodged and hid directly in a room next to him, avoiding a few bullets that came in.

However, as soon as he entered the room, Xia Feifei's face sank, and the person who had just come down from the upper floor on the opposite side was obviously stunned for a moment.

Obviously, Xia Feifei was superior, and after he finished shooting, the other party had not aimed at him.

Xia Feifei didn't have time to sigh about defeating the opponent, and immediately turned around and prepared to defend the enemy who might rush in, but the enemy didn't rush in, and the first thing that came in was a grenade.

Xia Feifei didn't think about it, he stepped forward and kicked it out quickly, and the grenade smashed into the opposite wall and bounced back into the corridor.

"Leak ......" exploded after a curse in the hallway.

Xia Feifei rushed out as fast as he could, and when he rushed to the door of the room next to him, the guy who threw the grenade just now got up from the ground, and before he could make a sound with his mouth open, Xia Feifei's gun went off.

"Fack, that damn guy is so powerful, we are no match for him when we fight alone, we have to rush out of the room together and kill him, otherwise, we will only be killed by him one by one." Someone said his plan on the intercom, apparently he didn't want to be approached like a chicken to kill him.

"But his marksmanship is excellent, and he is extremely fast, and if we rush out like this, it will be a complete exchange of lives for lives, and we will definitely have to kill several people." Someone voiced his concerns.

"Fack, you want to kill such a guy undead? You idiot, if you drag on like this, we'll all die, or you climb back to the third floor now and live a little longer. ”

People who are not from the same mercenary group, if they have different opinions, it is not so easy for one party to convince the other.

And when they were arguing, Xia Feifei killed another person, they could hear the gunshot, as long as the gun went off, they would instinctively think that it was their own person who was killed again.

"Shut up, I'm a lion, all obey my commands." Finally, a detachment leader who had just come down came forward, and he was the one who had the temporary command authority.

Suddenly, everyone stopped arguing, and another gunshot sounded like a punch in their hearts.
