Four days later, at about nine o'clock in the morning, when the streets of Renqiu were at their most lively, suddenly a terrible air defense siren sounded, and then, installed in the loudspeakers of various communities, intersections, and villages, the original news broadcast became an alarm: "Alarm! Air defense alert! Note that this is not a drill, please wait for everyone to enter the bomb shelter immediately to avoid it! All government workers, police, and self-defense personnel are invited to return to their air defense posts and help clear the crowd! Attention, this is not a drill! ……”

The streets immediately fell into chaos, and panicked people cursed, shoved, and ran in the direction of the nearest bomb shelter pointed by the wall.

Some people also looked up and scolded hatefully: "Little devil on dog days! Bully our cadet army without planes? ”

An informed person said: "Who said that we don't have a plane, our plane just hasn't flown back in Guangdong!" ”

"Grandma's, where's the little devil's plane? There is no one in the sky! ”

"Let's go, didn't it say on the radio, it's too late when you find out!"

A few minutes later, government workers and police appeared on the streets, as they had done in previous drills, and began to maintain order and divert the crowd. Under their rule, the chaos was brought under control, and people began to enter the nearby bomb shelters in an orderly manner, as they had done during previous exercises.

After about ten minutes, there was no one to be seen on the street. And in industrial areas, barracks, with the evacuation of workers and ordinary soldiers, the air defense units also moved into the preset combat positions. Among them, in the old camp, with the sound of rumbling motors, 54 carefully camouflaged ground and air tanks quickly entered their respective combat positions, the dust cover of the muzzle was removed, and the gun body was shaken high, pointing diagonally to the sky.

On Liyu Island in Baiyangdian, anti-aircraft guns and anti-aircraft machine guns stretched out from the concrete bunkers -- this will be another key air defense area of the air defense units of the Cadet Army.

After another ten minutes or so, a black cloud came from the northeast with a dull sound similar to thunder.

In a military camp on the western outskirts of Renqiu, Ouyang Yun stood at the lookout of the concealed command post, picked up the binoculars and looked at the sky covered by the black clouds, although he was already prepared in his heart, he couldn't help but gasp.

- The little devil really made a bloody investment this time, I'm afraid there are no less than 200 planes in this batch. The oppressive momentum brought by the cluster of two hundred planes was still concerned even if it was Ouyang Yun, who had seen a big scene in later generations.

Ouyang Yun did not know what to say, the exact number of this group of Japanese planes was 213, which took off from three airfields, of which 54 were fighters mainly serving as escorts and capable of carrying out ground attacks, and each plane had two 50-pound bombs hanging under the belly. The rest are bombers of all types.

What kind of scene when more than 200 planes flew together, if this was in an era of peace, Ouyang Yun might improvise a poem. Of course, as the supreme commander of the Cadet Army and the supreme head of the Jicha Special Administrative Region, she only felt an unprecedented pressure at this time.

"Buzz ......" When the plane flew over the concealed command post, the white tassel said whimsically: "It would be nice if there were giant fireworks, put them on at this time, even if you touch them, you can touch them and come down." ”

The speaker was unintentional, the listener was intentional, Ouyang Yun was stunned for a moment, and a vague concept appeared in his mind in an instant. He grabbed her hand tightly and asked, "What did you say?" Say it again! ”

The relationship between Ouyang Yun and Bai Tassel, Pan Meiren has always had a little taste. It was only because of the scar on her face that she found a sense of security psychologically. Speaking of which, the woman closest to Ouyang Yun is actually not Pan Meiren, nor Gu Lianyun, but Bai Tassel. As the colonel and battalion commander of Ouyang Yun's guard battalion, Bai Tassel naturally stayed by his side longer than anyone else.

The space of this newly established headquarters was not very large, and just behind them, a squad-sized guard stood in two rows with loaded guns close to the cave wall. Although all of them did not squint and looked straight ahead, but in total, there was such a large space, and Bai Tassel, who had a ghost in her heart, still felt the strangeness in their eyes, which made her face blush, and she hurriedly withdrew her hand. Trying to act like a businessman, he whispered, "I said, if only there was a giant firework, if you put it on it, it would definitely be able to knock down the plane." ”

This time, Ouyang Yun listened to all her words word for word, only to feel that there was a burst of clarity in his somewhat cloudy mind, and it had become clear that a wisp of memory on the edge of forgetting had become clear. It was a piece of news: a Japanese fireworks company actually made a firework with a projectile weighing 450 kilograms, which is said to be able to be launched at an altitude of more than 800 meters, and the blasting diameter of the fireworks is an astonishing 800 meters. Just imagine, if the small pill in the fireworks projectile is replaced with a bullet in the submunition projectile, wouldn't it be able to create a dead field within 800 meters? Thinking of this, Ouyang Yun slapped his helmet fiercely and said to himself, "I'm so stupid!" Rockets are hard to make, but fireworks are simple! Thinking of Bai Tassel's identity as a disciple of the Tang Sect, he eagerly looked at his guard battalion commander and asked, "Tassel, will you make fireworks?" ”

His words fell on Bai Tassel's ears, which was a little abrupt. The latter replied, "Yes." ”

"Great!" Ouyang Yun said with a smile, and then immediately ran to the phone, picked up the phone and asked for the phone numbers of the various air defense fronts, and then updated the orders one by one, requiring the various air defense units to save their strength when fighting, and to attack the Japanese aircraft as a supplement. Then, he asked Hou Debang again and told him to prepare some gunpowder to make fireworks as soon as possible, which would be of great use to himself.

As Ouyang Yun had predicted, the first target of the Japanese aircraft was the military camp and factory. More than 200 warplanes were divided into two groups over Renqiu, one rushing straight to the industrial park and the other rushing to the barracks.

Shortly after Ouyang Yun's new combat order was issued, the Jewish Independent Brigade, which took the lead in seizing the opportunity, fired the first shot of the Renqiu air defense battle.

Dietern is worthy of being a professional soldier trained by the German military academy, and he has his own unique views on air defense. He assigned his machine gunners in squads, and all of them were arranged around the barracks. In this way, when the Japanese machine wants to enter the combat position and start diving, the first thing that needs to be broken through is the anti-aircraft fire network composed of many sporadic machine guns.

"Hit!" As Stern's somewhat strange shout spread through the seven or eight horns of the ambush position, hundreds of machine guns spewed flames at the same time, and hundreds of rays of light dragged out of tracer bullets appeared in the sky. Immediately, two fighters were hit, one of them fell straight down like a bird with folded wings, while the other one jerked up and juggled in the air.

"Pay attention to evasion, there is anti-aircraft fire on the ground!" Almost at the same time as the fire appeared on the ground, the commander of the 10th Wing of the Japanese Kwantung Army Flying Group, who was in charge of commanding the bombing, immediately shouted loudly on the walkie-talkie, and at the same time pulled his plane up, turned around in mid-air, and adjusted the combat order: "The 10th Wing will follow me to clear the ground firepower points, and the other opportunities will be used to complete the bombing mission!" ”

“SHIT！” In a bunker on the ground, Stern saw that the dense enemy planes in the air suddenly rose en masse, and only one was shot down just now, he scolded loudly, pinched the walkie-talkie and gave the second order: "Stop shooting, evade!" Then, he took the lead and slipped into the cat's waist of the bomb shelter under the bunker.
