On the morning of the 29th day of the lunar month, the snow-covered wilderness was swept away by the cold wind. The warm current of spring is moving northward, and its troops begin to fight against the cold corps, and now the land in the north begins to recover weakly, and the footsteps of spring are gradually coming, and no force can resist it. A high wall wrapped in barbed wire, the buildings inside the high wall, revealing a ghostly atmosphere, no one knows what is going on inside this high wall.

The complex located in the Pingfang District has finally revealed its mystery, which is the base for the secret development of bacteriological weapons by Unit 731 of the Japanese Army. The Japanese army did not set up such a secret agency in the mainland, in order to hide people's eyes and ears. After the outbreak of the war of aggression against China, Unit 731 developed many bacteriological weapons and put them on the battlefield, playing a huge role. In particular, the poison gas bombs developed by Unit 731 have excellent results on the battlefield. In 1943, the second year after the outbreak of the Pacific War, the Japanese army lost in the Pacific and China battlefields, so the Japanese army base camp decided to start the chemical weapons development program, and the experimental base was set up in Unit 731.

In order to save the fate of defeat, the Japanese army took great pains to finally develop the R4, which decided the outcome of the battlefield. At this time, in the corridor outside a room with an iron fence, the leader of Unit 731, Captain Ishii, was proud and tall, trying to raise his head as high as possible. Around him gathered several generals in white coats. "General, it's time to get started!" A subordinate bowed his head, and Ishii said with a slight thought of emotion.

"Ladies and gentlemen, you will witness the splendor of the Great Japanese Empire, this is the 185th and last experiment of R4." Ishii waved his hand, and saw the empty room inside the iron fence, the secret doors on both sides opened, and two tall and burly Russians, wearing shorts and red eyes, rushed out head-on. The two are like bulls in heat, scuffling together in an instant. "Guys, they were inhaled with R4 gas in the steam room for 5 minutes each, and it turned out like this. This gas is diluted in the air for half an hour and then becomes ineffective, making it very useful for fighting on the battlefield. Ishii proudly explained that by this time one Russian had fallen to the ground, but the other Russian still did not stop attacking.

"There is a famous saying in the West, I don't go to hell, who goes to hell, for the sake of the Japanese Empire, the contemptible people have no hesitation and die." At this point, a Russian brutally killed his accomplice, and then rushed to the iron fence and roared, startling everyone. The Russians lost their target and began to circle the house. "Guys, do you see, this is our weapon ・・・・・・ victory."

"Report, base camp secret telegram!" A subordinate reported. After reading the telegram, Ishii entered his office and said: "The base camp judges that the Chinese army will continue to attack on the Shanhaiguan line and the Dalian line at the end of February. The base camp ordered us to send the first batch of R4 potions to the secret factory in Changchun to produce artillery shells and aerial bombs and put them into the battlefield as soon as possible. "General, after the first batch of medicines is inspected, it will be loaded tomorrow night at the earliest, and Changchun will be airlifted the morning after tomorrow." Ishii nodded.

But where did he think that a terrible adversary had targeted Ishii and his base with a keen sense of smell, so that Ishii and his subordinates were reduced to ashes in the explosion and fire, and they didn't know what was happening. When Ishii woke up, it was already the lights of ten thousand homes. It's been a long time since Ishii had such a sweet sleep, and Ishii feels comfortable. Soon, he appeared in the workshop and personally supervised every process.

At 4 p.m. on Chinese New Year's Eve, Ouyang Jian and Stilwell appeared on the runway side of Taipei Airport, at this time, B29 bombers were loading aerial bombs. "General Ouyang, according to your request, two B29 bombers are loaded with high-explosive incendiary bombs sent by your department, and two bombers are loaded with 300-pound and 500-pound high-explosive bombs respectively. Stilwell swore an oath, and Ouyang Jian knew that Stilwell was pointing.

This time, Chennault used the most advanced high-explosive aerial bomb with armor-piercing capability produced in the United States. While the two were chatting, four B29 bombers entered the runway one after another, and Ouyang Jian reached out and glanced at his watch, where the hour and minute hands pointed exactly to 5 o'clock. After the four U.S. B29 transport planes flew into the sky, Ouyang Jian and Stilwell hugged goodbye. "General Stilwell, thank you for your support. I want to rush to Tianjin immediately to keep abreast of the air raids. Soon, Ouyang Jian flew into the night sky on a special plane.

An hour after four U.S. B29 long-range bombers took off from Taipei Airport, Ouyang Jian's special plane landed at Tianjin Airport. At this time, the Airborne Forces were boarding the plane. Forty medium-sized transport planes were to transport the strength of one brigade to the skies over Harbin at one time. Ouyang Jian stepped off the plane, and Peng Dehuai, Su Yu, Luo Ronghuan and others stood on the apron to greet him. Ouyang Jian shook hands with everyone separately and said: "Mr. Peng, the US bomber will carry out air strikes on the target on time, the key is to synchronize the time, how is the situation here?" ”

"The times are calculated accurately and there are no large deviations. The key is to look at the first hammer deal. Brigadier Commander Meng Fei commanded the 1st Brigade to take the lead in launching airborne operations, do you want to meet him? "The big war is coming, so don't talk about the personal affairs of your children. Immediately after the departure of the first airborne assault team, I went to Beiping, and tomorrow we must use the Nanyuan airfield. "The materials in Beiping have been prepared, it depends on whether Chen Cheng can buy your face." "I think there's no problem, give him the opportunity to report to Lao Jiang, why not do that!"

As the two spoke, the transport planes began to taxi down the runway in turn, and the loud roar was deafening. "Brother Su, where is your First Army currently located?" "The First Army, under the name of Lalian, is currently on standby in the southeast of Nanyuan Airport, about 15 kilometers away from Nanyuan Airport. Rest assured that the Chief of the General Staff will quickly move to the airfield as soon as the order is received. Ouyang Jian stretched out his hand and glanced at his watch and said, "Mr. Peng, time is pressing, I will rush to Beiping immediately." The two sides shook hands, and Ouyang Jian boarded the jeep.

At 7 o'clock that night, in the wilderness on the west side of Harbin's Majiagou Airport, Shangguan Yun led 500 guerrillas to quietly approach the airport. At this time, Shangguan Yun held a sniper rifle in his hand, summoned several guerrilla leaders, and said: "At 8 o'clock, the plane will fly over the airport, our purpose is to attract the attention of the Japanese garrison, and at the same time contain the Japanese air defense forces and cover the airborne troops. After a while, I was ordered by the sound of my gunshots, and immediately after the shots were fired, I attacked. ”

After Shangguan Yun finished deploying, his eyes were aimed at the Japanese searchlight on the tower, and he was responsible for knocking out the searchlight and the Japanese machine gunner on the tower. I haven't touched a gun for a long time, and yesterday I deliberately trained in the field, but fortunately, the sniper's foundation is still there. Her location is about 400 meters from the tower, which is no problem. The waiting time was very slow and seemed to freeze. Shangguan Yun put his hands into the mink sleeves, lest the shooter be frozen for a while.

On Chinese New Year's Eve, firecrackers continue in the urban area of Harbin, and occasional fireworks rise into the sky. There was a peaceful scene in the city, and the entertainment venues in the city were occupied by Japanese officers.

In the icy night sky, four US B29 bombers were the first to arrive at the battlefield, and the air commander, Colonel Davis, first determined the target range through the latitude and longitude direction finder in the cab, and ordered each aircraft to quickly reduce the altitude.

Unit 731 is located in the vicinity of no civilian houses or other building facilities. Viewed from the air, the lights emitted from the buildings on the ground are clearly visible. Davis ordered bombers with high-explosive incendiary bombs to drop bombs first, which would create an incendiary fire that would allow for a clearer display of the target. There was no anti-aircraft fire on the ground, and the B29 bombers unscrupulously lowered their altitude, about 500 meters above the ground, and a bomber dropped a group of incendiary bombs.

When there was a roar of airplanes in the sky, Ishii rushed out of the workshop and looked into the sky, not knowing what was happening. When he saw the huge black shadow in the sky, he was immediately horrified, and immediately ordered to report to the city defense headquarters. It can already be over, 5 high-explosive incendiary bombs fell from the sky, 2 fell into the yard, and 3 fell outside. With a violent explosion, the flames suddenly filled the sky. After all, Ishii was old, and he was swept down by the air wave when he crawled to the door of the air-raid shelter. When he got up again, the second high-explosive incendiary bomb, 5 meters away from him, exploded.

The blast of air and flames threw Ishii into the air, quickly engulfed in flames. Immediately afterwards, high-explosive bombs were accompanied by incendiary bombs, which poured like dumplings. Under such a violent saturation blow, the complex was torn apart in a tremor, and fragments of houses and even human corpses flew in the air. After 20 minutes of artillery and bombardment, the complex, along with the creatures inside, disappeared. When the four B29 bombers left the airspace, the fire was still burning fiercely.

After the explosion disappeared, a terrible alarm sounded in the urban area of Harbin, and the power supply was cut off immediately, and the urban area was plunged into darkness. The commander of the Harbin city defense and the commander of the 211th Division, Takaji Muranaka, ordered the urban area to immediately implement light control, and the personnel quickly evacuated into the air-raid shelter. He believed that the enemy was going to bomb the city next, so it was necessary to deal with it urgently. However, just 10 minutes after he gave the order, the Majiagou Airport Guard Force reported: A large number of enemy fighters appeared over the airport, and the enemy suddenly launched an airborne operation!

In the face of such a crisis, Muraaka was stunned, and immediately ordered the nearby Japanese troops to rush to Majiagou Airport for reinforcements. The two orders contradicted each other, which exacerbated the confusion of the Japanese army. On the south side of Majiagou Airport, Shangguan Yun was immediately excited when he saw a violent explosion and skyrocketing fire sounding in the west. She quickly took aim and pulled the trigger, and the searchlight on the tower was shattered as the gun rang out. The Japanese machine gunners reacted quickly and quickly judged the target and began to strafe. The sound of gunfire was an order, and the partisans attacked.
