Suzuki Zuoxi, who was forced to be helpless, could only choose to continue the attack in the end, and Lu Yuan in the building had already transferred all the personnel and things that could be used to the 4th floor at this moment, and from the 3rd floor below, it was a battlefield that only belonged to Lu Yuan. Suzuki Zuoxi, who was fighting outside the building, was like an ant on a hot pot at the moment, and the soldiers belonging to the Suzuki Brigade entered the building in waves, and the gunfire and explosions in the building were sometimes fierce. Sometimes sparse, but the Imperial soldiers who entered the building were never seen.

Relying on his full-view map and storage space, Lu Yuan was like a killing god, rushing back and forth between the first and second floors, relying on the cover of the bulletproof shield in front of him, Lu Yuan killed the Japanese soldiers who rushed into the building one after another in the building. The gunfire was dense, it was Lu Yuan exchanging fire with the Japanese soldiers who rushed into the building, the gunfire was sparse, but it was Lu Yuan who was sneaking into the building. But regardless of the exchange of fire or a sneak attack, these Japanese soldiers who entered the building could only have one fate, that is, they turned into corpses. Lu Yuan completely unleashed all his combat effectiveness, but the Japanese army was outnumbered after all, and after repelling two attacks by the Japanese army in a row, Lu Yuan, who was already exhausted, had to be forced back to the 3rd floor.

The layers of corpses in the building shocked the Japanese soldiers who rushed in later, and the strong smell of blood diffused in the air made these Japanese soldiers secretly panic. "Boom" a * that fell from the ceiling of the corridor exploded in the Japanese army, and a few seconds after Lu Yuan pulled the * safety bolt was delayed, so that after this * passed through the hole, it exploded immediately. A scream accompanied by a large mass of blood appeared at the same time, and there were almost no dead ends in the explosion in the air, and seven or eight Japanese soldiers in the corridor on the second floor immediately fell.

"Smack... Syllable... "Smack" The other Japanese soldiers raised their guns to shoot, and the Japanese soldiers who fired the guns were not slow to react, but Lu Yuan in the corridor upstairs reacted faster than them. * Passing through the hole, Lu Yuan in the corridor upstairs had already used a large piece of wall brick taken out of the wall next to him to press the hole under his feet. The Japanese soldiers in the corridor downstairs shot to no avail, so they had to rescue their wounded and undead companions first, and Lu Yuan, who was alone on the 3rd floor, moved quickly to the corner of the stairs.

The staircase connecting the 2nd and 3rd floors is still there, but Lu Yuan has already arranged it on the stairs*, and the wires and detonators are next to Lu Yuan. The reason why he didn't blow up the stairs in advance was because Lu Yuan wanted to use this staircase to attract the Japanese army to throw themselves into the net to send them to death, the trap had been set, and now all Lu Yuan needed to do was to wait quietly for the appearance of the prey. The Japanese army attacked the first and second floors in succession, and although they encountered many interceptions and attacks by Lu Yuan during this period, in their opinion, victory was close at hand.

The headquarters building is only 4 floors, and now they have conquered the lower 2 floors in a row, and some Japanese soldiers who are eager for quick success have already carried away a little in their hearts, they think that as long as they work hard, they can completely conquer the entire headquarters building. Lu Yuan's bulletproof shield was placed horizontally at the corner of the stairs on the third floor at this moment, and through the shooting hole on the shield, Lu Yuan, who was kneeling behind the shield, looked directly at his eyes, paying close attention to the movement at the staircase below.

A Japanese steel helmet suddenly flashed at the staircase diagonally below, but immediately retracted, Lu Yuan behind the shield frowned, and almost in the next second, a * emitting green smoke flew up from the staircase diagonally below. Lu Yuan continued to use various obstacles in the building to shoot the Japanese army, and the Japanese army, which had already paid a large number of casualties and losses, also explored a set of countermeasures. Just like now, throw * first, and test the firepower, which the Japanese soldiers couldn't have thought of before.

Lu Yuan, who had been highly concentrated, suddenly found a * flying from obliquely below, and immediately didn't think about it, and immediately pulled the trigger with his right index finger, which had been hooking the trigger. I could only hear a long point, and the one that was attempted to be thrown up by the Japanese soldiers downstairs was hit by the barrage. *, who was hit by bullets in a row, had to spin back as he came from, and after hitting the wall, he fell back to the staircase below. The Japanese soldiers who had brewed their own bitter fruit downstairs had no time to react, and the Japanese army commander who threw * just now, together with the two Japanese soldiers beside him, was immediately swallowed up by the explosion.

The * who was hit back by the barrage exploded downstairs, but Lu Yuan, who was waiting upstairs, was unforgiving, and while the smoke downstairs had not yet dissipated, Lu Yuan immediately opened his bow left and right, and threw the two * into the corridor downstairs one after the other. There was an explosion downstairs, and gunpowder smoke poured out, but the figure of a Japanese soldier immediately appeared at the entrance of the staircase, and it turned out that the Japanese soldiers who entered the building later had already been killed. The footsteps downstairs were chaotic and dense, and Lu Yuan didn't need to open his full-view map to know that the Japanese troops downstairs must be indispensable.

A smoky* fell into the corridor downstairs again, and the footsteps instantly magnified several times, and then suddenly fell silent. "Boom"* exploded, but nothing was found in the * fragments that flew out, because the Japanese soldiers who had gathered here had already ducked into the room on their sides with oil on the soles of their feet before * exploded. After the explosion, the Japanese soldiers who had been hiding in the room reached out and stole it, but they did not know that the enemy who had been holding the upper floor had already rushed down the stairs while they were dodging the explosion, and now they were standing sideways at the corner of the stairs.

The gunfire rang out suddenly and fiercely, and the Japanese soldiers on the first floor eagerly looked up, but without a ladder, the Japanese soldiers on the first floor could not climb up immediately. Before the Japanese soldiers on the outer wall climbed into the second floor, there were already several rooms on the second floor that were bursting with smoke and fire, and in the continuous explosions, fragments of rifles and military uniforms mixed in the air waves, and flew out of the windows. Seeing this, Suzuki's face became even more ugly, he could never have imagined that this building would be so difficult to attack, especially since his infantry brigade had already paid a lot of casualties and losses.

Suzuki Zuoxi was speechless about the current war situation, and Xu Huanshan also paid close attention to these, and in these days, Xu Huanshan secretly guessed more than once how long Lu Yuan, who was guarding the Japanese army headquarters, could hold out. Whenever he got the news that the Japanese army had increased its troops in Hongkou District, Xu Huanshan's worries would be a little more. However, a whole week has passed, and gunshots and explosions are still heard in the direction of the Japanese headquarters, which shows that Lu Yuan and the others are still continuing to exchange fire with the Japanese army, and they are still holding on.

Once upon a time, when all the blue sky and white sun flags in Shanghai disappeared, a large dark cloud hung over the heads of the people of Shanghai. The bloody Nationalist army was gone, and the arrogant Japanese army came to Shanghai, and as the Japanese army continued to expand the area of engagement and aggression in China, the Japanese army's control in Shanghai was also more and more enlarged. The appearance of Lu Yuan and others made a few rays of sunshine suddenly appear in this city that had been shrouded in clouds, which made many Chinese people who were originally numb see the dawn and hope of victory.

After seven days of perseverance, Xu Huanshan didn't know how Lu Yuan did it, but what Xu Huanshan could be sure of was that these seven days were definitely not good for Lu Yuan and the others. For this reason, Xu Huanshan also specially came forward to contact the people of the military commander in Shanghai, but it is a pity that the joint action of the Shanghai underground party and the military commander failed to attract the attention of the Japanese army.

It was about to get dark, and Xu Huanshan, who was standing in front of the window, looked intently in the direction of Hongkou District, and at this moment he was a little worried, worried that he would not be able to hear the gunshots and explosions that he had long been accustomed to. Lu Yuan, who was shooting continuously at this moment, would not have thought that outside Hongkou District, there would be many people worried about himself and others. At this moment, Lu Yuan only had these helpless Japanese stragglers on the second floor in his eyes, and Lu Yuan, who was alone, had to shoot all these fish that slipped through the net before more Japanese soldiers climbed into the second floor.

"Boom" flew out of the room* and exploded, and the corridor was suddenly filled with flying dust and a thick smell of gunsmoke. The bulletproof shield in front of Lu Yuan seemed to have been suddenly hit by a sledgehammer, and Lu Yuan had to temporarily stop shooting and lean sideways against the back of the shield, using his body to ensure that the shield would not be knocked over by the explosion of air. Lu Yuan stopped shooting here, and immediately those Japanese soldiers found a chance to counterattack, accompanied by a crackling sound on the bulletproof shield, several bullets fired by the Japanese army hit the wall next to Lu Yuan.

The brick and stone debris that was hit by the bullet hit Lu Yuan's face, and immediately brought out a hot pain, but Lu Yuan didn't have time to pay attention to this, and moved forward with his left shoulder against the shield, and the * barrel that protruded from the shield shooting hole once again spat out the gun's flames. * The bullets in the magazine were rapidly consumed, and large balls of blood appeared one after another with the sound of gunshots, and it took about a cigarette before Lu Yuan finally stopped shooting.

Open the full-view map, the Japanese soldiers on the 2nd floor were shot and killed by Lu Yuan, I don't know if the Japanese soldiers were timid, or the Japanese troops outside the building gave the order to retreat, and the Japanese soldiers who climbed the ladder on the outer wall of the building also withdrew. Finally survived again! Lu Yuan, who was sweating profusely, sat directly in the corridor on the second floor, and at this moment, on his side, in addition to the corpses of Japanese soldiers all over the ground, only the weapons scattered around the corpses and the large bloodstains that could be seen everywhere remained.

Lu Yuan, who had exerted too much physical strength, gasped for a while on the second floor, and after his physical strength recovered slightly, he got up and began to check those weapons and ammunition. If you want to continue to hold on, weapons and ammunition are indispensable, otherwise even if Lu Yuan and the others have the physical strength and ideas, I am afraid that there will be no way to continue to face the crazy attack of the Japanese army.
