The Japanese soldier Cao who was in the front didn't know that he had become Lu Yuan's prey, and jumped up with his feet to escape a corpse on the ground, and before the Japanese soldier Cao landed on his feet, he suddenly seemed to be punched head-on, and the Japanese soldier Cao who was in the air with his feet raised his head, and the whole person fell heavily on his back and fell on the cement floor. The other Japanese soldiers who rushed behind him couldn't help but froze for a moment, and the Japanese soldier closest to him subconsciously turned his head to look, but let out an exclamation, only to see a bloody hole on Jun Cao's head.

The screams that burst out of his throat only lasted for half of the time, and then suddenly disappeared, and the Japanese soldier who let out the screams had already collapsed next to the Japanese soldier Cao. Without hearing the gunshots or seeing the flames of the gunshots, two people had already fallen in succession, and the remaining Japanese soldiers immediately dispersed, and some even looked for cover to stop advancing. The speed of the Japanese army's dodge was not slow, but Lu Yuan shot faster, just in the blink of an eye, Lu Yuan fired two more shots, and in the open space in front of the building, there were two more corpses again.

At the cost of four deaths, the Japanese troops who tried to break through the front of the building retreated, and Wang San and others, who were scattered on the second and third floors and were closely prepared for battle, although they did not quite understand what had happened, they knew that the Japanese army had retreated. The cheers came from several rooms on the second and third floors, and Dong Peng and the others on the second floor felt inexplicably relaxed in their hearts, while Lu Yuan, who was alone on the fourth floor, had already changed into a heavy sniper rifle at this moment.

After nightfall, it was not appropriate for Lu Yuan to switch to a heavy sniper rifle at this moment, but the Japanese troops surrounding the headquarters building felt that they were too far away and exposed themselves to the surrounding lights without any care, which gave Lu Yuan an opportunity. Lu Yuan, who was lying on the desk, slowly moved the muzzle of the gun, and the first one he locked on was a Japanese officer with a command knife on his waist.

With a muffled "bang", a gun flame more than half a foot long suddenly burst out from a window on the fourth floor of the headquarters building, and then looked at the Japanese truck parked opposite the headquarters building. When there was a bang, a large hole appeared in the driver's door of the truck, and the Japanese officer standing in front of the door suddenly broke in two from his waist. The Japanese troops around the truck were all stunned, and a big living person was suddenly broken into two in front of their eyes, such a strange and tragic scene was the first time they had seen it in their lives.

Lu Yuan, who was hidden on the 4th floor, immediately left the window after firing five large-caliber bullets in a row, and sure enough, just a few breaths later, the Japanese troops who reacted launched an intensive counterattack. The rain of bullets continued to hit the window frame and the outer wall, and Lu Yuan had already withdrawn the heavy sniper rifle at this moment and moved to the roof of the building. Squatting on the edge of the roof, Lu Yuan first scanned the number of Japanese troops around him with a full-view map, and then focused on the two groups of Japanese troops advancing from both flanks.

The Japanese troops in front had already retreated, and the Japanese troops who had advanced from both flanks had already moved to the front gate of the headquarters building, and when Lu Yuan fired his heavy sniper rifles, these Japanese soldiers were ready to break into the building. It's just that when they were about to attack, they sadly found that the gate of the headquarters was stubbornly blocked, not to mention, looking through the crack in the door, there were still tables and chairs piled up behind the gate.

Piling up tables and chairs in the lobby on the first floor, this is Lu Yuan's attention, Lu Yuan never thought that he could block the Japanese army outside the gate, since he couldn't do it, then he would create more trouble for the attacking Japanese army. The Japanese troops outside the gate had no choice but to send someone to report back the situation here, and the Japanese officers in command on the spot directly ordered the attack regardless of 3721. With a bang, the closed door was blown open, and the tables, chairs, and sundries piled up behind the door were also pushed open by the airflow.

Dong Peng and others, who were waiting at the corner of the stairs on the second floor, did not expect that the Japanese troops outside the building would use such a direct attack method. "Boom" and "Boom" before rushing into the building, the Japanese army had already thrown * continuously, and the continuous explosion * was regarded as opening a passage for these Japanese soldiers, and those tables, chairs and miscellaneous items did not cause them much trouble.

"Attack!" Seeing that the two groups of soldiers had already rushed into the building, the Japanese soldiers who were waiting in front also shouted, and finally rushed up to the headquarters building with heavy gunfire. The weapons that Lu Yuan prepared for Dong Peng and others were obviously superior to the Japanese army, but their military literacy and battlefield experience were inferior to the Japanese army. In the face of the impact of the Japanese army and the rain of bullets that continuously hit the wall of the corridor, Dong Peng, who was cowering at the corner of the stairs, could not find a chance to counterattack at all.

There was a bang of "boom", and at the moment of crisis, Dong Peng pressed the handle of * according to Lu Yuan's explanation. I only heard a bang, and the staircase connecting the second floor collapsed in the explosion, and the * that Lu Yuan had arranged before finally came in handy. Without the stairs, even if the Japanese army rushed into the headquarters building, they would not be able to really threaten Dong Peng and them on the second floor for a while. Dong Peng detonated*, Wang San and the others came back to their senses and took advantage of the situation to launch a counterattack.

The sound of explosions sounded continuously, and the dust dispersed with the explosions gradually filled the entire lobby, and the Japanese troops, whose visibility had dropped to the lowest point, refused to retreat in such an unfavorable situation. Lu Yuan had already descended from the roof of the building at this time, but he never shot, but quietly watched the reaction of Dong Peng and the others. After all, civilians can't be compared with professional soldiers, although the * sharpest in the hands of Dong Peng and others, but most of the bullets they fired fell in the air, Lu Yuan's brows were tightened, according to their speed of consuming bullets, the little ammunition they brought in, I am afraid that it will not be able to support even two days.

"Boom" "Boom" Lu Yuan, who had already moved to the 3rd floor, began to throw*, with the guidance of a full-view map, and the dust scattered on the 1st floor had almost no effect on Lu Yuan. "Bang... Boom... "There was a loud bang on the first floor, and the Japanese soldiers who were coming head-on began to dismantle the windows on the first floor, trying to rush into the building through the windows. "Upstairs, all up." Lu Yuan, who had stopped throwing*, shouted loudly towards Dong Peng and the others on the second floor, and after a while, the disgraced Dong Peng rushed up the stairs to the third floor.

"Continue up, you go to the fourth floor and wait, don't go to the window to look out, take care of your spirits first." Lu Yuan didn't ask Dong Peng to stay on the third floor, but urged them to continue to move up, and soon, only Lu Yuan himself was left on the third floor. The Japanese troops who burst in through the window soon appeared in the lobby on the first floor, but they immediately found that the stairs had been blown down, and without the stairs, they naturally had no way to go up to the second floor.

Whether it was to build a human tear or set up a wooden ladder, they would inevitably expose themselves to the sight of the enemy upstairs, and the Japanese army, knowing this, had to suspend the offensive. The Japanese army suspended the offensive, but Lu Yuan upstairs didn't want to leave a respite for the opponent, and when Dong Peng and the others moved all the way up, Lu went down the stairs to the second floor. The assault rifle hanging on the belt on his chest had already been held in Lu Yuan's hand, and the barrel slowly stretched out from the broken part of the stairs, and Lu Yuan, who was kneeling at the corner of the stairs, gently put his right index finger on the trigger of the assault rifle.

Lu Yuan pointed at a gun in a room on the first floor, and in the display of the full-view map, there were at least four Japanese soldiers in this room pointed by Lu Yuan with a gun. These Japanese soldiers were bound to enter the room on the first floor through the window, but after a slight pause, they followed the traces left by their previous companions, and moved forward briskly, preparing to leave the room and enter the lobby. With a crisp sound of "dang", the Japanese commander, who had already stepped out of the room with one foot, fell backwards on his back, and the other Japanese soldier who followed him was slightly stunned, and was hit in the neck by the next bullet that followed.

The artery between the neck and neck was opened by a bullet, and a large stream of plasma erupted instantly, staining the door frame and walls with a layer of red. The face of the third Japanese soldier was also splashed with blood, and the warmth on his cheeks made the Japanese soldier subconsciously twist his body. With a whoosh, a bullet grazed the Japanese soldier's body, striking a crater in the wall. Lu Yuan blocked the Japanese soldiers in a room with one gun, and paid several casualties in a row, and the Japanese soldiers in the room finally found helplessly that they couldn't rush out.

The other Japanese soldiers outside the building also noticed something strange at this moment, and the Japanese soldiers who rushed into the other rooms cautiously stuck to the corridor and moved towards the stairs little by little, but they didn't know that their whereabouts had already been shown by the full-view map. Finding that the Japanese soldiers who entered through the window were assembling in the corridor, Lu Yuan, who was kneeling at the corner of the stairs, smiled slightly, then pulled on the mask, took out a *, and threw it to the corridor below.

The Japanese troops gathered in the corridor more and more, and before they could rush out of the corridor, they saw a green smoke* flying into the corridor. "*, there is*." The Japanese soldiers in the hallway shouted, turning around and trying to burrow into the rooms next to them. "Boom" flew into the corridor * exploded, a few Japanese soldiers who couldn't dodge shouted in pain in the explosion, those Japanese soldiers who were lucky enough to avoid the room next to them secretly shouted luck in their hearts, but they didn't want to, and the next second another * appeared in the corridor.

The Japanese light machine gun that moved forward to the main entrance of the building opened fire at the right time, and only then did it throw two * Lu Yuan, who was immediately suppressed by the Japanese machine gun fire and could not raise his head, so he had to retreat back into a room. From the time Lu Yuan shot to the time he was forced to push into the room behind him, the whole process was only about a minute, but Lu Yuan caused more than 20 casualties to the Japanese army, which put great pressure on the Japanese army.
