Du Yufan is like a soul messenger from hell, sending fresh lives to hell, and he uses the same technique to kill all the mercenaries on the fifth and fourth floors.

By this time, more than ten minutes had passed, and the search on the three floors below had almost been completed, so Du Yufan did not go down, but came to a corpse, searched for a few grenades from its body, and carried his submachine gun and walked to the stairs.

"Boom!"

The flames were so bright that the grenade exploded at the staircase on the fourth floor, and the powerful impact even made the entire building shake slightly.

"On the fourth floor, everyone goes up!"

The leader of the Blood Wolf Mercenary Group saw the dazzling firelight, his spirit was shocked, and he immediately picked up the walkie-talkie and gave orders, the people outside were waiting for him, and the mercenaries in the building were all rushing to the fourth floor, all of them looked excited, as long as they caught Du Yufan, the task would be completed, and the sky-high reward would go into the bag, enough for them to be free for a long time.

When the mercenaries entered the fourth floor, a black object suddenly shot out and landed at their feet, and they wore night vision devices, and they could see clearly that it was a grenade.

"Get down!"

The squad leader roared, however, it was too late, the grenades exploded, these grenades were extremely powerful, the stairs were almost cut off, the rubble flew, eight mercenaries were directly killed by the terrifying impact, and two were more sad, they were shot by the gravel, the impact of the gravel was comparable to a bullet, directly into their heads, and they refused to die without dying.

After the grenade exploded, everything fell silent.

The dust and fog rolled, the smell of smoke and gunpowder was permeated, and after half a sound, another group moved forward slowly, highly concentrated, cautious, shuttling through the smoke, they thought they were strong, they were also extremely nervous at the moment, cold sweat broke out, the hand of the nest gun trembled slightly, they were really afraid.

As the mercenaries walked out of the smoke, a huge black shadow suddenly fell from the sky.

"Da Da Da!"

The mercenaries, who were nervous to the extreme, did not hesitate, the submachine guns were aimed at the black shadow, and they fired wildly, the flames were swallowed, the guns were piercing, and in the blink of an eye, the black shadow was blasted into a ball of flesh.

"Stop!"

The team leader waved his hand to stop everyone from shooting, and then, step by step, slowly walked towards the black shadow, while the other nine mercenaries were observing the surroundings and not letting go of any suspicious places.

"Da Da Da!"

When all these people walked to the side of the lump of flesh, the piercing gunshot rang out again, and Du Yufan appeared out of nowhere, holding a submachine gun, and shooting wildly.

"Puff puff!"

Blood splashed, the mercenaries' bodies did not have the slightest resistance, they were shot through by bullets, these mercenaries were unwilling, with the impact of the bullets, their bodies trembled violently, they wanted to fight back, but the blood flowed, not only brought piercing pain, but also took away their strength, they really couldn't do anything.

In the blink of an eye, nine mercenaries died tragically one after another, from life to death, they didn't even have time to shoot a shot, and they died extremely aggrieved.

Only the squad leader escaped, he was originally in the center of these mercenaries, and his companions used them as his shields, besides, his strength was also stronger than others, his body rolled, and he was extremely embarrassed to avoid Du Yufan's strafing, when he was extremely well hidden, the gunfire just stopped, but Du Yufan's figure also disappeared without a trace.

Actually, Du Yufan didn't want to stop, but the gun ran out of bullets, so he had to stop, and then, he didn't change the gun, and he didn't need to use a gun at all to solve the problem of a team leader.

"Dang!"

A faint collision sound suddenly sounded behind the team leader, the team leader's body shook, and he turned back reflexively, and at the same time as he turned around, the submachine gun was already fired.

"Da Da Da!"

Bullets fired, holes appeared in the walls, cracks appeared, dust flew and rubble splattered, but there was not even half a figure.

"Hey, I'm here."

Without warning, Du Yufan appeared strangely behind the team leader, blowing a breath of cold air on his neck, and his cold voice was like a ghost whisper.

"Ahh

The determined squad leader let out a scream, feeling creepy, but his reaction was not unpleasant, and at the same time as he was frightened, the dagger appeared in his hand and stabbed the rear, and then, the rear was empty, and the dagger pierced directly into the air.

"Whew!"

Just as the team leader was about to turn around, the cold wind struck, Du Yufan appeared in front of him strangely again, his eyes were staring at his eyes, the distance between the two was less than five minutes, the team leader was frightened one after another, and his spirit was about to collapse, he roared, clenched the dagger, and stabbed Du Yufan in the chest.

"Peng!"

However, before his dagger stabbed Du Yufan, Du Yufan had already punched him in the forehead, the night vision device immediately shattered, and a bloody hole appeared in his head, and suddenly his brain was dizzy, his eyes were black, and his body fell backwards uncontrollably, and finally leaned against the wall, and the dagger and submachine gun in his hand fell to the ground.

Du Yufan rushed up with an arrow step, held the dagger in his hand, and then stabbed into the throat of the squad leader, the throat was immediately pierced, the dagger pierced deeply into the wall, the squad leader was nailed to the wall by the dagger, his body twitched, his pupils gradually dilated, and soon he was silent.

In a short time, two more squads were destroyed, before and after, five squads with a total of fifty people, died tragically at the hands of Du Yufan, only the team that searched the first floor survived, however, they would soon be sent by Du Yufan to see Satan.

When the teams on the second and third floors rushed along the stairs to the third floor, the teams on the first floor took out ropes and climbed down the window to the fifth floor, they wanted to fight back and forth, if Du Yufan escaped to the fifth floor, they could just give him a head-on blow.

However, their hearts soon sank.

The gunshots quickly disappeared, and everything fell silent, as if nothing had happened, no news came from his companions, and Du Yufan did not flee to the fifth floor.

The squad leader took out the walkie-talkie and contacted the two squad leaders below, but unfortunately, there was no other sound except for the sound of the current, and the squad leader's heart sank, and he felt bad, so he had to contact the blood wolf leader who was waiting for news outside.

However, just as he was about to speak, he saw a figure flashing in front of him out of the corner of his eye, and the team leader was shocked, gave up the call, and commanded the team members to move in the direction of the black shadow.

Du Yufan went to the sixth floor first, and after not finding the enemy, he returned to the fifth floor, where he wanted to wipe out all these mercenaries.

"Phew!"

Du Yufan suddenly appeared in front of a person, and just as this person was about to scream, the dagger stabbed out like lightning, directly into his mouth, and pierced his head.

This is already the fifth, and there are five more waiting for him.
