Dong Peng hid on the 4th floor alone, with the flag that Lu Yuan had entrusted to him, as well as the weapons and ammunition captured from the Japanese army that had been moved to the 4th floor before. The gunfire downstairs was sometimes strong and sometimes weak, and from time to time there would be a bang, and Dong Peng, who was terrified in his heart, unconsciously loaded almost all the 38 rifles at hand, and he was also ready to fight at any time. It's just that what Dong Peng didn't expect was that the sound of gunshots and explosions kept switching back and forth between the first and second floors, but they never spread to the third floor.

Fighting meant casualties, and Suzuki Sasai, who had already become angry, personally led his troops to attack, and the Japanese attack was far more powerful than before. But Lu Yuan is not ambiguous, although he is just alone, but the arrangements he made in advance are not small, just the various obstacles and * arranged in the hall on the first floor are enough for him to toss the Japanese army. The bullets were intertwined back and forth like flying locusts, and Lu Yuan, who kept changing positions in the hall, blocked the Japanese army from the main entrance of the building for the first minute.

Two magazines in a row were empty, and Lu Yuan began to consciously retreat, because at this moment, Japanese soldiers had already rushed into the corridor on the first floor through the windows of the outer wall. Lu Yuan did not immediately retreat to the second floor along the long ladder behind him, but directly retreated behind a pile of masonry rubble, "Boom... Rumble... Boom...", several explosions sounded continuously, and at the main entrance of the headquarters building, there was already a smoke of gunpowder rising at this moment, and the * that Lu Yuan had arranged in advance was finally triggered by the Japanese army.

Taking advantage of the fact that the dust from the explosion had just dispersed, Lu Yuan, who was hiding behind the pile of masonry and rubble, suddenly rushed out, and in just a few breaths, he had already rushed to the entrance of the corridor blocked by a large pile of masonry. There were about 20 Japanese soldiers who rushed into the room on the first floor through the windows of the building, but to their disappointment, Lu Yuan had already blocked the exit of the corridor with a large pile of masonry and rubble, and when they entered the corridor, they could only see the general situation in the hall through some gaps, but they couldn't get through the whole person at all.

The more than 20 Japanese soldiers who found that this was a dead end did not immediately exit the corridor by the same route, but moved the masonry and rubble, trying to open the blocked corridor exit, and it was at this time that Lu Yuan suddenly appeared behind the masonry and rubble. "It's passed, it's passed, you can go out." The sudden appearance of a gap in the masonry made the Japanese soldiers moving the masonry in the corridor cheer, but in the next moment, outside the gap in the masonry pile, there were continuous smoke* flying in.

Lu Yuan didn't give the other party time to react at all, so he continuously threw Ji * from the gap in the masonry pile into the corridor, and the continuous explosions came as scheduled, and Lu Yuan, who had already turned around, slanted the corners of his mouth to reveal a sneer. When the smoke cleared, Suzuki entered the hall filled with the smell of gunpowder smoke and blood, and all eyes could see were the corpses of Imperial soldiers in khaki uniforms, while the enemy who had been stubbornly resisting here before was long gone.

Lu Yuan actually did not leave the hall on the first floor, but took advantage of the blind spot of the Japanese army's thinking, and was wearing a Japanese military uniform at the moment, mixed in with a group of wounded soldiers. The air in the hall on the first floor was cloudy and his vision was dim, and Lu Yuan's face was full of stains at the moment, and the Japanese soldiers who were in a hurry to go upstairs did not suspect this ordinary soldier with blood stains on his left shoulder. A few Japanese soldiers who were in a hurry to perform, without waiting to search the entire hall, had already begun to climb down the long ladder to the second floor, and Lu Yuan suddenly showed a * at this moment.

The 38 rifle in the hands of the little soldier next to him suddenly turned into a Thomson*, and Shinichi Tachikawa, who had just been a soldier for 2 years, did not react immediately, he just stared blankly at the * in Lu Yuan's hand, until this * was fired by Lu Yuan. "Da Da Da" Thomson*, who was equipped with a drum and a strong tongue of fire, first swept down the Japanese soldiers who had climbed the long ladder, and then turned around and shot at the other Japanese soldiers in the hall.

The hall was full of corpses and fragments of masonry, except for a few places where the masonry was piled up, there was almost no cover to dodge, and Lu Yuan shot a fan-shaped barrage, and soon hit a large area of blood mist in the dimly lit hall. The benefits of putting the enemy in and fighting became apparent at this moment, and although the Japanese quickly launched a counterattack, the bolt-action rifles used by the Japanese were not superior in close combat.

After a few explosions, Suzuki Sashi, who was lucky not to move deeper into the hall, quickly retreated to the outside of the building, escorted by a group of soldiers. Lu Yuan did not start a pursuit, but focused all his attention on the Japanese soldiers who were still in the hall, and Tachikawa Shinichi, who first discovered the appearance of * in Lu Yuan's hands, did not escape the doom of the barrage. "Boom... Boom..."The Japanese troops who withdrew from the building did not retreat there, but scattered on both sides of the main entrance, throwing * into the building in succession.

Lu Yuan, who was also unavoidable in the hall, had to use the storage space to quickly move the masonry on his side to simply build a blocking bunker, and Lu Yuan finally built a temporary position in the hall at the cost of adding two more wounds to his body. The Japanese soldiers who were forced out of the building were now fully convinced that Lu Yuan was the last one to resist, and since they already knew that the opponent was only the last man left, Suzuki Zuoxi also ordered to slow down the pace of the attack, because he wanted to capture this last resistance alive.

The Japanese soldiers outside the building also drove over and climbed directly up to the 2nd or 3rd floor along the long ladder, and then attacked the resistance in the hall from top to bottom, but they didn't expect that Lu Yuan had used the storage space to clear the floors in all the rooms on the 2nd and 3rd floors, in other words, the pile of brick and stone fragments and the long ladder behind Lu Yuan was the only way to go upstairs. Lu Yuan made all the preparations for the destruction of the cauldron and the ship, just to delay it until dawn and give Dong Dongpeng upstairs a chance to raise the Han flag, but the Japanese army did not know this.

After a moment's pause, the sound of gunfire and explosions rang out again, and Lu Yuan no longer spared, took out the heavy sniper rifle and explosive crossbow arrows, and fought with the Japanese army in the dark with the cover of the brick and stone fragments in front of him. Time passed minute by minute, in Dong Peng's almost frantic waiting, the sky finally appeared white, and the gunfire downstairs finally stopped, Dong Peng carried * and quietly moved to the staircase to look down, his eyes were full of Japanese army's khaki uniform.

Lu Yuan finally couldn't stand it, and almost all the ammunition in the storage space was knocked out by him, otherwise he would not be able to hold out for a full three hours in the continuous attack of the Japanese army alone. The Japanese army under Suzuki Sasai also paid a heavy price, and the number of casualties in a whole field infantry brigade was as high as seventy percent in a few days of attack, which is one of the main reasons why Suzuki Sashi wanted to capture Lu Yuan alive.

Lu Yuan, who was leaning against the wall and facing the main entrance of the building, sat on the ground, his eyes were dark, and the blood flowing from the wound had already accumulated a small puddle of blood under him. Feeling the sound of footsteps in front of him, Lu Yuan opened the full-view map for the last time, and saw the red dots densely appearing on the full-view map, and Lu Yuan, who was already powerless to raise his head, tilted the corners of his mouth to reveal a sneer.

Ignoring the obstruction of the soldiers around him, Suzuki Zuoxi insisted on stepping forward and walking in front of Lu Yuan, squatting down and looking at Lu Yuan for a while, and then he let out a long breath, he never thought that in the end, he would be so young after resisting them alone for more than three hours. Lu Yuan's mind had already sounded a ten-second countdown at this moment, which was the prompt sound of the system after he opened the light curtain to confirm his departure, and when the system read out the last one, Lu Yuan's right hand, which had been hanging down, finally pressed the button.

With a loud "boom", when Lu Yuan's body suddenly turned into a little starlight under the frightened gaze of Suzuki Zuoxi and others, a ball of flame burst out from the place where Lu Yuan was sitting paralyzed just now, and the weapons and equipment that Lu Yuan couldn't take away were mixed with the last remaining 20 kilograms*, which instantly became Lu Yuan's last gift to the Japanese army. The loud noise from downstairs made the tears that had been in Dong Peng's eyes finally flow out, and a few minutes later, the black Han flag that had been used by Lu Yuan in the French Concession was raised on the roof of the Japanese headquarters building.

Lu Yuan, who had confirmed that he had left this era, did not know what happened afterward, and Dong Peng, who had fulfilled Lu Yuan's entrustment, did not choose to surrender, but chose to be bombarded by the infantry artillery transferred by the Japanese army together with the Japanese army headquarters building. A week later, four boxes sent by the Shanghai underground party finally arrived in distant Yan'an, containing all the weapons and equipment that Lu Yuan had made himself, as well as a handwritten letter from Lu Yuan to the top of Yan'an.

Through the Shanghai underground party, the high-level leaders in Yan'an were actually no strangers to Lu Yuan, and the weapons and ammunition that Lu Yuan provided to the Eighth Route Army and the guerrillas free of charge were enough for the Eighth Route Army to form three main regiments. In addition, there were also a large amount of funds, radio weapons, and other materials provided by Lu Yuan to the underground party organizations in Shanghai and Tianjin free of charge, all of which were enough for Yan'an to treat Lu Yuan as his own. The weapons and equipment that Lu Yuan handed over to Yan'an were regarded as treasures by the Eighth Route Army Arsenal, and they played a role in making the enemy tremble in the subsequent war against Japan and the war of liberation.

As for the handwritten letter that Lu Yuan handed over to the high-level leaders in Yan'an, except for a few high-level officials who had read the letter, no one knew the content of the letter. In the war memorial built after the founding of the People's Republic of China, Lu Yuan's letter is preserved as a national treasure, but visitors can only see the envelope, as for the contents, no one knows. On the eve of Japan's surrender, Yan'an sent a special envoy to Chongqing to talk secretly with the Nationalist Government, and on the subsequent issue of Japan, Yan'an and the Nationalist Government resolutely disagreed with the proposal of the U.S. military to host the Ryukyus, and put forward a claim against Japan in the name of the country, a month after Japan's full surrender, 100,000 Kuomintang-Communist joint troops landed on the Japanese mainland, and they will be stationed on the four islands of Japan as a supervisory force until Japan completes almost the same compensation as the sky-high price.
