Knowing that Dapeng wouldn't last long, he didn't shoot at the fixed points above the iron window again, and saw that two fixed points were broken, or he stepped forward and grabbed the iron bar on it and pulled it down......

"Wow"

Most of the sturdy iron windows were torn down, but they didn't fall completely, and it was obviously not so easy to jump out of the small gap, and it was extremely vulnerable to the opponent's attack when jumping.

"Hold on for fifteen seconds."

The impatient and unwise did not hurriedly greet Dapeng, and then his body rushed upward, and the whole person jumped onto the broken window edge at once, nor did he raise his foot to kick the window outside, and at the same time greeted Da Lei outside:

"I'm coming out and telling me where the second floor is accessible."

"Two points above, a window is open."

With Da Lei's prompt, Yifei, who had already arrived outside the building, reached out and grabbed the horizontal edge above his head, stepped on the crumbling broken windows, and through the drainage pipe next to him, he reached the open window in three ways and two verticals, and jumped on the windowsill with one body.

Although this is a single window, the inside is still sealed with iron bars, and it is not a prescription to take medicine, a few shots broke the fixed point of the iron window inside, and the iron seal blocked by the window was kicked to the ground in the house, nor did it fly into the house with a scoop of body immediately behind.

After entering, he realized that the reason why this window was open was because this was the bathroom, and he didn't have time to take care of the smell and environment inside, so he rushed to the corridor with a gun.

The guards left behind in the building may have gathered downstairs, and the sound that occurred on the second floor obviously could not cover the gunfire of the two sides below, and the one who entered the corridor did not quickly move in the direction of the sub-corridor where he and Dapeng were forced to retreat just now, and when approaching the turn of the stairs leading to the first floor, he also looked down from the railing of the building, and saw a Northern Dynasty man hiding at the corner of the stairs, holding an AK47 submachine gun in one hand, and an American-made grenade from his body with the other hand, Hand it to your mouth and use your teeth to pull off the safety pin spring on the grenade.

"Poof, poof, poof."

It was not without the slightest ambiguity, he fired a few shots at the back of the heart of the Northern Dynasty, and before he could throw the grenade out of the insurance, the kid was killed by a sneak attack from behind him, and the grenade also rolled to the ground at the same time as his body pounced, and exploded next to him with a 'boom'.

After removing the threat on this side, he didn't inform the Dapeng who was guarding the house, and then turned around and ran upstairs again, raising his gun and running quickly along the corridor to the main staircase, the explosion behind him gave him a good cover, and before the attackers on the other side could react, he had already moved to the staircase, raised his gun and slowly walked down, and just walked halfway up the stairs, he saw a person holding a gun and shooting into the corridor.

"Poof, poof."

Two more shots, this one was directly shot in the head, the dead body fell to the ground, not moving down quickly, seeing the attacker hiding behind the wall on the other side was looking back and looking up in horror, it was obvious that he was shocked by the sudden death of his companion, but it was not that he didn't have time to care about what the other party was thinking, raised his hand and shot it in the center of the eyebrows, a large covered corpse fell to the ground, and it was prudent not to casually make up two shots for the Northern Dynasty man who had been knocked down at the staircase before, and after a while, the corridor was quiet again.

"Safety!"

Yifei and Dapeng gathered together again, but they didn't dare to be careless, and searched the first floor room by room again, and after making sure that there was no longer a threat, the two walked up the stairs to the top.

The house-to-house search of the second floor twice made Yifei and Dapeng clueless again, they had carefully explored all the rooms in this building, and the people of the Northern Dynasty who were originally guarding here had become corpses and fell everywhere, except for the two of them, there were no other living creatures in this building, Feng Shaolan was even more nowhere to be found, looking at the dark and empty corridor, Yifei and Dapeng lost their claims for a while.

"No, what are we going to do? Let's not always stand here stupidly, the toss just now will inevitably attract some lively people, let's go out and find another way. ”

Dapeng reminded Yifei, and Yifei nodded helplessly, and the two walked downstairs while calling Da Lei outside.

The remoteness of the location of the small building and the sound effect in the building greatly reduced the sound of explosions and gunfights spread outward, and most of the sound leaked out was also diluted by the noise generated by the working machinery and vehicles in the storage and transportation yard, despite this, the anomaly here still attracted the attention of some people, Da Lei reported that someone had already looked at the location of the sound with a probe and asked them to come out quickly.

Seeing that there were not a few steps left from the first floor, and he didn't stop suddenly, he grabbed Dapeng beside him and asked:

"Dapeng, we didn't see the monitoring room when we searched here just now, right?"

He asked, pointing to a surveillance probe in the building.

"I didn't see it, I prove I didn't."

"Keep looking, there must be something we have overlooked, there is something wrong in this building."

"The second floor has been turned over by the two of us, definitely not, and the first floor has not been seen, unless there is a basement here."

"That's right, it should be right under our feet."

With that, the two of them went downstairs at the same time and turned to the back of the stairs.

Sure enough, bypassing the pots of green plants that seemed to be used for decoration next to the stairs, in the corner at the back of the stairs, an iron door more than half a person high appeared in the sight of the two, and instead of stepping forward and gently pushing the iron door open a gap.

As the iron door slowly opened, a slightly steep, dim narrow staircase gradually appeared, Dapeng was about to enter with a gun, and was dragged by the side of Yifei, nor after making a silent gesture to Dapeng, and then quickly returned to the depths of the corridor behind him, and in the blink of an eye, he turned back here, and saw Yifei holding an American-made grenade in his hand, Dapeng couldn't help but give a thumbs up to Yifei.

After gently pulling out the safety pin spring for a few seconds and delaying for a few seconds, he threw the grenade under the stairway, and then quickly closed the iron door, and heard the grenade jumping to the bottom of the stairs below, with a muffled sound of 'boom', and the explosion time was just right.

Before the smoke and dust below turned up, Yi Fei had already rushed to the bottom of the stairs, accompanied by the aftermath of the explosion, there was also a person's forcible moaning sound, which was about to approach the bottom of the stairs, and Yifei's body pounced downward, and the whole person rushed to the bottom of the stairs head-on, and the dust that could not be dispersed as soon as possible made this place chaotic, nor was it lying on the ground with closed eyes and holding his breath, and there was a burst of non-stop rapid fire at the place where he groaned, until all the bullets in the magazine were emptied and the magazine was replaced, Dapeng has followed closer, and the forcible moaning sound that he heard before is also silent at this time.
